Qualitative study of decisions about infant feeding among women in east end of London

ObjectiveTo improve understanding of how first time mothers who belong to a socioeconomic group with particularly low rates of breast feeding decide whether or not to initiate breast feeding.DesignQualitative semistructured interviews early in pregnancy and 6-10 weeks after birth.SettingWomen’s homes in east end of London.Subjects21 white, low income women expecting their first baby were interviewed mostly at home, often with their partner or a relative. Two focus groups were conducted.ResultsWomen who had regularly seen a relative or friend successfully breast feed and described this experience positively were more confident about and committed to breast feeding. They were also more likely to succeed. Exposure to breast feeding, however, could be either a positive or a negative influence on the decision to breast feed, depending on the context. Women who had seen breast feeding only by a stranger often described this as a negative influence, particularly if other people were present. All women knew that breast feeding has health benefits. Ownership of this knowledge, however, varied according to the woman’s experience of seeing breast feeding.ConclusionsThe decision to initiate breast feeding is influenced more by embodied knowledge gained from seeing breast feeding than by theoretical knowledge about its benefits. Breast feeding involves performing a practical skill, often with others present. The knowledge, confidence, and commitment necessary to breast feed may be more effectively gained through antenatal apprenticeship to a breastfeeding mother than from advice given in consultations or from books.

Key messages

• Women who have seen successful breast feeding as part of their daily lives and perceive this as a positive experience are more likely to initiate breast feeding
• Embodied knowledge gained through seeing breast feeding may be more influential than theoretical knowledge about the health benefits for women of lower social class
• Listening to pregnant women talking about breast feeding could help clinicians assess the relative importance of theoretical and embodied knowledge for each woman
• Women hoping to breast feed but with little exposure to breast feeding may benefit from an antenatal apprenticeship with a breastfeeding mother
• Ideally apprenticeship would be with a breastfeeding mother from her social network to minimise the potential barriers of embarrassment and lack of confidence with strangers

     

Gendered perceptions on infant feeding in Eastern Uganda: continued need for exclusive breastfeeding support

Background

In resource-poor settings, HIV positive mothers are recommended to choose between 'Exclusive breastfeeding' (EBF) or 'Exclusive replacement feeding' (ERF). Acceptability, Feasibility, Affordability, Sustainability and Safety (AFASS) has been the World Health Organization (WHO)'s a priori criteria for ERF the last ten years. 'AFASS' has become a mere acronym among many workers in the field of prevention of mother-to-child transmission of HIV, PMTCT. Thereby, non-breastfeeding has been suggested irrespective of social norms. EBF for the first half of infancy is associated with huge health benefits for children in areas where infant mortality is high. But, even if EBF has been recommended for a decade, few mothers are practicing it. We set out to understand fathers' and mothers' infant feeding perceptions and the degree to which EBF and ERF were 'AFASS.'

Methods

Eight focus groups with 81 informants provided information for inductive content analysis. Four groups were held by men among men and four groups by women among women in Mbale District, Eastern Uganda.

Results

Two study questions emerged: How are the different feeding options understood and accepted? And, what are men's and women's responsibilities related to infant feeding? A mother's commitment to breastfeed and the husband's commitment to provide for the family came out strongly. Not breastfeeding a newborn was seen as dangerous and as unacceptable, except in cases of maternal illness. Men argued that not breastfeeding could entail sanctions by kin or in court. But, in general, both men and women regarded EBF as 'not enough' or even 'harmful.' Among men, not giving supplements to breast milk was associated with poverty and men's failure as providers. Women emphasised lack of time, exhaustion, poverty and hunger as factors for limited breast milk production. Although women had attended antenatal teaching they expressed a need to know more. Most men felt left out from health education.

Conclusion

Breastfeeding was the expected way to feed the baby, but even with existing knowledge among mothers, EBF was generally perceived as impossible. ERF was overall negatively sanctioned. Greater culture-sensitivity in programs promoting safer infant feeding in general and in HIV-contexts in particular is urgently needed, and male involvement is imperative.

The study was part of formative studies for the ongoing study PROMISE EBF registered at http://clinicaltrials.gov (NCT00397150).     

Postpartum depression and infant feeding practices in a low income urban settlement in Nairobi-Kenya

Background

Postpartum depression can compromise caregiving activities, including infant feeding practices, resulting in child malnutrition. The purpose of this study was to examine the effects of postpartum depression on infant feeding practices and malnutrition among women in an urban low income settlement in Nairobi-Kenya. We conducted a cross-sectional study based in Kariobangi North Health Centre in Nairobi County. The study sample included 200 mother-infant pairs visiting the Maternal and Child Health clinics for infant immunization at 6–14 weeks postpartum. We assessed postpartum depression using the Edinburgh Postpartum Depression Scale. Infant feeding practices were assessed based on World Health Organization infant and young child feeding guidelines. Nutritional status (weight for age) was ascertained using infants’ growth monitoring card (percentiles and z-score). We conducted logistic regression analyses to determine the relative odds of non-exclusive breast feeding and infant underweight among mothers with postpartum depression.

Results

The prevalence of PPD was 13.0% (95% CI 8.3–17.7%). Taking into account differences in socioeconomic status of depressed and non-depressed mothers, non-depressed mothers had a 6.14 (95% CI 2.45–13.36) times higher odds of practicing exclusive breastfeeding than mothers who were depressed. Mothers with PPD had a 4.40 (95% CI 1.91–11.93) time higher odds of having an underweight infant than mothers without depression.

Conclusions

This study contributes towards filling the knowledge gap regarding the adverse effects of postpartum depression on infant health in sub-Saharan Africa. We recommend more research on PPD using longitudinal designs to establish temporal ordering of these important public health problems and development of community-based interventions to address post-partum depression.

     

“Can breast feeding help you in later life? Evidence from German military heights in the early 20th century”

Considerable literature exists on the benefits of breast feeding on the health and survival of infants and young children, but there is less on the effects on later life outcomes. One such measure of health and well-being that has received attention in the historical literature is terminal adult stature. Information on height is rather widely available; however, it is much more difficult to obtain data on breast feeding. One country that does have such information is Imperial Germany (1871-1919). A number of physicians and local health officials collected information on the incidence and duration of breast feeding early in the 20th century, particularly because of concern about the unusually high infant mortality rates in parts of Germany. Hallie Kintner has surveyed the published results of these studies. The information on the prevalence of breast feeding for the period 1903/10 has been inputed into a database of demographic and economic variables for the counties (Regierungsbezirke) of Germany (1850-1939). There are also published data on heights of military recruits from the Imperial German military forces in 1906. These can be linked to areas in the database and related to breast feeding practices and infant mortality both contemporaneously and approximately 20 years previous to 1906. Results indicate a significant effect of infant feeding practices on later life outcomes operating through infant health conditions, proxied by the infant mortality rate.     

Infant feeding practices and breastfeeding duration in Japan: A review

The Japanese health system places great emphasis on healthy development. However, the prevalence of Exclusive Breastfeeding at one month postpartum between 1980 and 2005 has remained unchanged, fluctuating between 42% and 49%. At the same time, the Any Breastfeeding prevalence has gradually increased from about 80% to 95%. In 2010, the latest national breastfeeding report showed that ‘exclusive’ and ‘any’ breastfeeding rates have improved. However, as the World Health Organization (WHO) definition of breastfeeding practices was not used in this study or in other national surveys, it is difficult to interpret these latest results. While the Japanese government has launched several promotion projects, there have been few studies and reviews of risk factors that influence breastfeeding duration. The objectives of this review were to summarise the factors that have influenced the duration of breastfeeding in Japan to provide information relevant to breastfeeding promotion programs. A search of electronic databases in Japanese and English was undertaken up to 2011. The inclusion criteria for this review were studies that focused on infant feeding practices and targeted Japanese mothers, fathers, or health professionals, but excluded mothers’ friends and peer groups. In total, 12 articles were selected for the final analysis. Smoking status, low birth weight of infants and maternal perceptions of insufficient breast milk supply were negative influences on breastfeeding duration, while support from husbands/partners is associated with continued breastfeeding. Some factors that have been found to be associated with breastfeeding in other countries, including maternal age, family income, maternal educational levels, and living with grandparents of infants have not been confirmed in Japan. While the national breastfeeding rates were higher than other countries of similar health status, inconsistent knowledge of breastfeeding benefits and inappropriate hospital practices remain in Japan may be associated with increased the use of infant formula and reduced breastfeeding duration. Most of the studies reviewed were cross-sectional in design, with only a limited number of cohort studies. Also many published studies used small sample sizes. Cohort studies of infant feeding practices with larger sample sizes are required to monitor trends in rates and risk factors for breastfeeding outcomes.     

Analgesic effect of breast feeding in term neonates: randomised controlled trial

ObjectivesTo investigate whether breast feeding is effective for pain relief during venepuncture in term neonates and compare any effect with that of oral glucose combined with a pacifier.DesignRandomised controlled trial.Participants180 term newborn infants undergoing venepuncture; 45 in each group.InterventionsDuring venepuncture infants were either breast fed (group 1), held in their mother''s arms without breast feeding (group 2), given 1 ml of sterile water as placebo (group 3), or given 1 ml of 30% glucose followed by pacifier (group 4). Video recordings of the procedure were assessed by two observers blinded to the purpose of the study.ResultsMedian pain scores (interquartile range) for breast feeding, held in mother''s arms, placebo, and 30% glucose plus pacifier groups were 1 (0-3), 10 (8.5-10), 10 (7.5-10), and 3 (0-5) with the Douleur Aiguë Nouveau-né scale and 4.5 (2.25-8), 13 (10.5-15), 12 (9-13), and 4 (1-6) with the premature infant pain profile scale. Analysis of variance showed significantly different median pain scores (P<0.0001) among the groups. There were significant reductions in both scores for the breast feeding and glucose plus pacifier groups compared with the other two groups (P<0.0001, two tailed Mann-Whitney U tests between groups). The difference in Douleur Aiguë Nouveau-né scores between breast feeding and glucose plus pacifier groups was not significant (P=0.16).ConclusionsBreast feeding effectively reduces response to pain during minor invasive procedure in term neonates.

What is already known on this topic

Current pharmacological treatments are not appropriate for pain relief during minor procedures like venepuncture or heel prick in newborn infantsOral sweet solutions, non-nutritive sucking, and skin to skin contact reduce procedural pain in newborn infants

What this study adds

Breast feeding during a painful procedure effectively reduces the response to pain in newborn infantsThe analgesic properties of breast feeding are at least as potent as the combination of sweet solutions and a pacifier     

Breast feeding and risk of breast cancer in young women. United Kingdom National Case-Control Study Group.

OBJECTIVE--To investigate whether breast feeding is related to subsequent risk of breast cancer. DESIGN--Population based case-control study designed primarily to investigate the relation between oral contraceptives and risk of breast cancer; data obtained from questionnaires administered by interviewers, general practitioner notes, and family planning clinic records. SETTING--11 health regions in Britain. SUBJECTS--Women diagnosed with breast cancer before age 36 living in the defined study areas. One control per case, matched for age, was selected from the list of the case''s general practitioner. 755 case-control pairs were interviewed. MAIN OUTCOME MEASURES--Duration of breast feeding each liveborn infant; timing of return of menses; hormone use; other risk factors for breast cancer. RESULTS--Risk of breast cancer fell with increasing duration of breast feeding (relative risk = 0.94 per three months'' breast feeding; test for trend p = 0.026) and with number of babies breast fed (relative risk = 0.86; test for trend, p = 0.017). Breast feeding each baby for longer than three months conferred no additional benefit. Breast feeding was more strongly negatively associated with risk of breast cancer than duration of postpartum amenorrhoea (chi 2 test for trend, p = 0.69). Hormonal suppression of lactation was unrelated to risk of breast cancer (relative risk = 0.96 per episode of suppressed lactation; test for trend, p = 0.72). CONCLUSIONS--These results suggest that breast feeding protects against the development of breast cancer in young women.     

Maternal Obesity and Breast‐feeding Practices Among White and Black Women

Despite the increase in obesity among women of reproductive ages, few studies have considered maternal obesity as a risk factor for breast‐feeding success. We tested the hypothesis that women who are obese (BMI = 30–34.9) and very obese (BMI ≥35) before pregnancy are less likely to initiate and maintain breast‐feeding than are their normal‐weight counterparts (BMI = 18.5–24.9) among white and black women. Data from 2000 to 2005 South Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) were used. The overall response rate was 71.0%; there were 3,517 white and 2,846 black respondents. Black women were less likely to initiate breast‐feeding and breast‐fed their babies for a shorter duration than white women. Compared to normal‐weight white women, very obese white women were less likely to initiate breast‐feeding (odds ratio: 0.63; 95% confidence interval (CI) = 0.42, 0.94) and more likely to discontinue breast‐feeding within the first 6 months (hazard ratio (HR) = 1.89; 95% CI: 1.39, 2.58). Among black women, prepregnancy BMI was neither associated with breast‐feeding initiation nor with breast‐feeding continuation within the first 6 months. Because very obese white women are less likely to initiate or continue breast‐feeding than other white women, health professionals should be aware that very obese white women need additional breast‐feeding support. Lower rates of breast‐feeding among black women suggest that they should continue to be the focus of the programs and policies aimed at breast‐feeding promotion in the United States.     

Child feeding and human rights

Background

Despite high levels of breastfeeding initiation in Australia, only 47 percent of women are breastfeeding (exclusively or partially) six months later, with marked differences between social groups. It is important to identify women who are at increased risk of early cessation of breastfeeding.

Methods

Data from the three arms of a randomised controlled trial were pooled and analysed as a cohort using logistic regression to identify which factors predicted women continuing to feed any breast milk at six months postpartum. The original trial included 981 primiparous women attending a public, tertiary, women's hospital in Melbourne, Australia in 1999–2001. The trial evaluated the effect of two mid-pregnancy educational interventions on breastfeeding initiation and duration. In the 889 women with six month outcomes available, neither intervention increased breastfeeding initiation nor duration compared to standard care. Independent variables were included in the predictive model based on the literature and discussion with peers and were each tested individually against the dependent variable (any breastfeeding at six months).

Results

Thirty-three independent variables of interest were identified, of which 25 qualified for inclusion in the preliminary regression model; 764 observations had complete data available. Factors remaining in the final model that were positively associated with breastfeeding any breast milk at six months were: a very strong desire to breastfeed; having been breastfed oneself as a baby; being born in an Asian country; and older maternal age. There was an increasing association with increasing age. Factors negatively associated with feeding any breast milk at six months were: a woman having no intention to breastfeed six months or more; smoking 20 or more cigarettes per day pre-pregnancy; not attending childbirth education; maternal obesity; having self-reported depression in the six months after birth; and the baby receiving infant formula while in hospital.

Conclusion

In addition to the factors commonly reported as being associated with breastfeeding in previous work, this study found a negative association between breastfeeding outcomes and giving babies infant formula in hospital, a high maternal body mass index, and self-reported maternal depression or anxiety in the six months after the baby was born. Interventions that seek to increase breastfeeding should consider focusing on women who wish to breastfeed but are at high risk of early discontinuation.     

Qualitative evidence syntheses of attitudes and preferences to inform guidelines on infant feeding in the context of Ebola Virus Disease (EVD) transmission risk

BackgroundBreast-feeding holds considerable potential to reduce infant mortality. Feeding choices, already complex, take on additional complexity against a backdrop of the risk of transmissible Ebola Virus. This review describes the factors that influence infant feeding and attitudes of pregnant women, mothers, family members and health practitioners, policy makers and providers (midwives) concerning infant feeding when there is a risk of Mother-to-Child (MTC) transmission of Ebola Virus Disease (EVD).MethodologyA systematic review of qualitative studies identified through rigorous searches of thirteen online databases and additional citation searches of included studies was undertaken. Search terms included breast-feeding, breast-feeding, infant feeding; Ebola; and qualitative, interview(s) and findings. Independent extraction of data by two reviewers using predefined extraction forms. Studies were assessed using the CASP Qualitative checklist.Principal findings5219 references were screened. 38 references related specifically to Ebola, and five papers met the inclusion criteria with data gathered from two settings: Guinea and Sierra Leone. The EVD outbreak had a significant impact on beliefs, attitudes, and resources to support infant feeding practices negatively affecting the nutritional status of children. The evidence from these studies highlight the need for guidance and appropriate psychosocial support need to be available to mothers who display symptoms and become infected and to front-line staff who are giving advice. Communities need to be engaged because stigma and fear may hinder uptake of appropriate interventions. The EVD outbreak caused multi-level system disruption akin to that seen following a natural disaster, meaning that logistics and coordination are critical and need adequate resourcing. Food production and distribution, and malnutrition screening are also disrupted and thereby compounding compromised nutritional status. The limited number of relevant studies highlights the need for further primary research, particularly in translation of messages to local settings.ConclusionsAn EVD outbreak causes multi-level disruption that negatively impacts infant feeding and child care practices. Negative impacts have multiple causes and successful planning for Ebola outbreaks requires that nutrition of infants and young children is a priority. Lessons from the Ebola pandemic have wider applicability to other pandemic contexts including Covid-19.     

Inappropriate infant feeding practices of HIV-positive mothers attending PMTCT services in Oromia regional state,Ethiopia: a cross-sectional study

Background

Inappropriate infant feeding affects the probability of mother-to-child transmission of HIV and HIV-free survival of infants. However, in Ethiopia limited evidence exists regarding the infant feeding practice of mothers who are HIV-positive. The aim of this study was to determine the prevalence and predictors of inappropriate infant feeding among HIV-positive mothers attending the prevention of mother-to-child transmission (PMTCT) service in Adama and Bushoftu towns, Oromia, central Ethiopia.

Methods

A cross-sectional study was conducted in ten PMTCT service providing health facilities in the towns; 283 mother-infant pairs were enrolled. Appropriate infant feeding practice was defined as exclusive breastfeeding in the first six months of age. Logistic regression was employed to analyze the data and the outputs are presented using adjusted odds ratio (AOR) with 95% confidence intervals (CI).

Results

One hundred thirty of the infants were aged below six months, 103 between 6 and 11 months and 50 were older than 12 months. The prevalence of inappropriate infant feeding was 14.5% (95% CI 10.6, 18.7). About 6.3% and 8.3% practiced exclusive replacement feeding and mixed feeding respectively, in the first six months. Only 1.8% ever expressed their breast milk to feed their baby and none practiced wet nursing. Among 38 mothers who already discontinued breastfeeding 52.6% did so before 12 months of age. Mothers who were HIV-positive and had received antenatal (AOR?=?0.05: 0.01, 0.30) and postnatal visits (AOR?=?0.18: 0.04, 0.81); received infant feeding counseling (AOR?=?0.18: 0.06, 0.55); and disclosed their HIV status to their partners (AOR?=?0.28: 0.12, 0.63), showed a reduction of practicing inappropriate infant feeding. Mothers having breast problems (AOR?=?4.89: 1.54, 15.60) and infants with mouth ulcers (AOR?=?6.41: 2.07, 19.85) were more likely to practice inappropriate feeding.

Conclusion

Prompt management of breast complaints in mothers and mouth ulcer in infants; and provision of nutrition counseling to HIV-positive mothers, especially during antenatal and postnatal care, may help to improve the infant feeding practices for HIV exposed infants.

     

Qualitative study of evidence based leaflets in maternity care

ObjectiveTo examine the use of evidence based leaflets on informed choice in maternity services.DesignNon-participant observation of 886 antenatal consultations. 383 in depth interviews with women using maternity services and health professionals providing antenatal care.SettingWomen''s homes; antenatal and ultrasound clinics in 13 maternity units in Wales.ParticipantsChildbearing women and health professionals who provide antenatal care.InterventionProvision of 10 pairs of Informed Choice leaflets for service users and staff and a training session in their use.ResultsHealth professionals were positive about the leaflets and their potential to assist women in making informed choices, but competing demands within the clinical environment undermined their effective use. Time pressures limited discussion, and choice was often not available in practice. A widespread belief that technological intervention would be viewed positively in the event of litigation reinforced notions of “right” and “wrong” choices rather than “informed” choices. Hierarchical power structures resulted in obstetricians defining the norms of clinical practice and hence which choices were possible. Women''s trust in health professionals ensured their compliance with professionally defined choices, and only rarely were they observed asking questions or making alternative requests. Midwives rarely discussed the contents of the leaflets or distinguished them from other literature related to pregnancy. The visibility and potential of the leaflets as evidence based decision aids was thus greatly reduced.ConclusionsThe way in which the leaflets were disseminated affected promotion of informed choice in maternity care. The culture into which the leaflets were introduced supported existing normative patterns of care and this ensured informed compliance rather than informed choice.

What is already known on this topic

Informed Choice leaflets are widely used in maternity care but little is known about their ability to influence informed choice and decision makingHigh quality information is essential for promoting informed choice but is insufficient by itself

What this study adds

Time constraints and other pressures on health professionals resulted in a lack of discussion of the content of the leafletsFear of litigation, power hierarchies, and the technological imperative in maternity care limited the choices availableHealth professionals promoted normative practices rather than choice, and as women valued their opinions this led to the promotion of informed compliance rather than informed choice     

Low-Income US Women Under-informed of the Specific Health Benefits of Consuming Beans

Background

Bean consumption can reduce chronic disease risk and improve nutrition status. Consumer knowledge of bean health benefits could lead to increased intakes. Low-income women have poorer health and nutrition, but their level of knowledge about bean health benefits is unknown. Beans are a familiar food of reasonable cost in most settings and are cultural staples for Hispanics and other ethnicities. Study objectives were to assess awareness of bean health benefits among low-income women, and to evaluate any differences by acculturation status for Hispanic women in the Southwestern United States.

Methods

A convenience sample of 406 primarily Mexican-origin (70%) low-income women completed a survey on knowledge of bean health benefits and general food behaviors. Principal components analysis of responses identified two summary scale constructs representing “bean health benefits” and “food behaviors.” Acculturation level was the main independent variable in chi-square or ANOVA.

Results

The survey completion rate was 86% (406/471). Most women agreed or strongly agreed that beans improved nutrition (65%) and were satiating (62%). Over 50% answered ‘neutral’ to statements that beans could lower LDL cholesterol (52%), control blood glucose (56%) or reduce cancer risk (56%), indicating indifference or possible lack of knowledge about bean health benefits. There were significant differences by acculturation for beliefs that beans aid weight loss and intestinal health. Scores on the bean health benefits scale, but not the food behavior scale, also differed by acculturation.

Conclusions

Limited resource women have a favorable view of the nutrition value of beans, but the majority did not agree or disagreed with statements about bean health benefits. Greater efforts to educate low-income women about bean health benefits may increase consumption and improve nutrition.     

Prelacteal feeding and associated factors in Ethiopia: systematic review and meta-analysis

Background

Prelacteal feeding can be defined as giving any solid or liquid foods other than breast milk during the first three days after birth. It affects timely initiation of breastfeeding and exclusive breastfeeding practices. Even though the issue was investigated in Ethiopia, fragmented and inconsistent findings were reported. Therefore, the main objective of this meta-analysis was to estimate the pooled prevalence of prelacteal feeding and associated factors in Ethiopia.

Methods

The preferred reporting items for systematic reviews and meta-analyses guideline was followed. Articles were systematically searched through different searching mechanisms. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument adapted for cross-sectional study design was used for quality assessment of each individual study. The total of 28 studies were included and analyzed. The random effect model was used to estimate the pooled prevalence; subgroup analysis and meta-regression were performed to identify the probable source of heterogeneity. Both Egger’s, and Begg’s test were used to check publication bias. The effects between associated factor variables, and prelacteal feeding practices were tested.

Results

A total of 492 studies were retrieved and 28 studies were included in the meta-analysis. The pooled prevalence of prelacteal feeding practice in Ethiopia was 25.29% (95% Confidence Interval [CI] 17.43, 33.15) with severe heterogeneity (I² =?99.7, p <?0.001) and no publication bias. Antenatal care (Odds Ratio [OR] 0.25, 95% CI 0.09, 0.69), counselling on infant feeding (OR 0.37, 95% CI 0.22, 0.63), timely initiation of breastfeeding (OR 0.28, 95% CI 0.21, 0.38) and an urban residence (OR 0.47, 95% CI 0.26, 0.86) had lower odds, while home birth had higher odds (OR 3.93, 95% CI 2.17, 7.10) of prelacteal feeding in Ethiopia.

Conclusions

In Ethiopia, one in four children were given prelacteal foods. Mothers who gave birth at home are more prone to give prelacteal foods. Whereas, antenatal care, timely initiation of breastfeeding, counseling on infant feeding and an urban residence decreases prelacteal feeding practices in Ethiopia. Therefore, the government and health institutions should focus to increase maternal health service utilization and promote infant and young child feeding practices according to the guideline.

     

Impact of breast feeding on admission for pneumonia during postneonatal period in Brazil: nested case-control study

ObjectiveTo determine whether breast feeding protects infants against pneumonia and whether the protection varies with age.DesignNested case-control study.SettingPelotas, southern Brazil.SubjectsCases were 152 infants aged 28-364 days who had been admitted to hospital for pneumonia. Controls were 2391 cases in a population based case-control study.ResultsInfants who were not being breast fed were 17 times more likely than those being breast fed without formula milk to be admitted to hospital for pneumonia (95% confidence interval 7.7 to 36.0). This relative risk was 61 (19.0 to 195.5) for children under 3 months old, decreasing to 10 (2.8 to 36.2) thereafter. Supplementation with solids was associated with a relative risk of 13.4 (7.6 to 23.5) for all infants and 175 (21.8 to 1405.1) for those under 3 months old.ConclusionBreast feeding protects young children against pneumonia, especially in the first months of life. These results may be used for targeting intervention campaigns at the most vulnerable age groups.

Key messages

• Pneumonia is the leading cause of death in children under 5 years old across the world
• In Brazil infants who were not breast fed were 17 times more likely than those receiving breast milk alone to be admitted for pneumonia
• The relative risk of admission was 61 for children under 3 months of age, decreasing to 10 thereafter
• Supplementation with solids was associated with a relative risk of 13.4 for all infants
• Mothers must be encouraged to breast feed very young infants and be advised of the right time to introduce supplementary foods

     

Changes in maternal postpartum adiposity and infant feeding patterns

The relationship between maternal fatness and infant feeding practices was studied in 46 healthy Caucasian women from parturition to 6 months postpartum. Mothers reported infant feeding practices in diary form throughout the study. Weight, triceps and subscapular skinfolds, and midarm circumference were measured on seven occasions. Upper arm fat area was computed. All women breast fed their infants for at least 5 months, with no nonbreast milk food introduced for at least 2 months. All women had declining or stable postpartum weights. Linear regressions of upper arm fat area on days since parturition were used to ascertain overall direction of change in adiposity for each woman. Declining fat area occurred in 17 cases and was associated with a breast-feeding pattern of short frequent feeds. In the remaining 29 cases, increasing fat area was associated with significantly longer and less frequent feeds. It is hypothesized that these different fat change patterns result from differential activity of adipose tissue lipoprotein lipase, which is itself mediated by serum prolactin concentration. Relevance of these findings for resolution of the controversy surrounding the critical body composition hypothesis and lactation amenorrhea is discussed.     

Pressuring and restrictive feeding styles influence infant feeding and size among a low‐income African‐American sample

Objective:

The prevalence of overweight among infants and toddlers has increased dramatically in the past three decades, highlighting the importance of identifying factors contributing to early excess weight gain, particularly in high‐risk groups. Parental feeding styles and the attitudes and behaviors that characterize parental approaches to maintaining or modifying children's eating behavior are an important behavioral component shaping early obesity risk.

Design and Methods:

Using longitudinal data from the Infant Care and Risk of Obesity Study, a cohort study of 217 African‐American mother‐infant pairs with feeding styles, dietary recalls, and anthropometry collected from 3 to 18 months of infant age, we examined the relationship between feeding styles, infant diet, and weight‐for‐age and sum of skinfolds.

Results:

Longitudinal mixed models indicated that higher pressuring and indulgent feeding style scores were positively associated with greater infant energy intake, reduced odds of breastfeeding, and higher levels of age‐inappropriate feeding of liquids and solids, whereas restrictive feeding styles were associated with lower energy intake, higher odds of breastfeeding, and reduced odds of inappropriate feeding. Pressuring and restriction were also oppositely related to infant size with pressuring associated with lower infant weight‐for‐age and restriction with higher weight‐for‐age and sum of skinfolds. Infant size also predicted maternal feeding styles in subsequent visits indicating that the relationship between size and feeding styles is likely bidirectional.

Conclusion:

Our results suggest that the degree to which parents are pressuring or restrictive during feeding shapes the early feeding environment and, consequently, may be an important environmental factor in the development of obesity.     

Early enteral feeding versus "nil by mouth" after gastrointestinal surgery: systematic review and meta-analysis of controlled trials

ObjectiveTo determine whether a period of starvation (nil by mouth) after gastrointestinal surgery is beneficial in terms of specific outcomes.DesignSystematic review and meta-analysis of randomised controlled trials comparing any type of enteral feeding started within 24 hours after surgery with nil by mouth management in elective gastrointestinal surgery. Three electronic databases (PubMed, Embase, and the Cochrane controlled trials register) were searched, reference lists checked, and letters requesting details of unpublished trials and data sent to pharmaceutical companies and authors of previous trials.ResultsEleven studies with 837 patients met the inclusion criteria. In six studies patients in the intervention group were fed directly into the small bowel and in five studies patients were fed orally. Early feeding reduced the risk of any type of infection (relative risk 0.72, 95% confidence interval 0.54 to 0.98, P=0.036) and the mean length of stay in hospital (number of days reduced by 0.84, 0.36 to 1.33, P=0.001). Risk reductions were also seen for anastomotic dehiscence (0.53, 0.26 to 1.08, P=0.080), wound infection, pneumonia, intra-abdominal abscess, and mortality, but these failed to reach significance (P>0.10). The risk of vomiting was increased among patients fed early (1.27, 1.01 to 1.61, P=0.046).ConclusionsThere seems to be no clear advantage to keeping patients nil by mouth after elective gastrointestinal resection. Early feeding may be of benefit. An adequately powered trial is required to confirm or refute the benefits seen in small trials.

There is no benefit in keeping patients “nil by mouth” after gastrointestinal surgerySeptic complications and length of hospital stay were reduced in those patients who received early enteral feedingIn patients who received early enteral feeding there were no significant reductions in incidence of anastomotic dehiscence, wound infection, pneumonia, intra-abdominal abscess, and mortality     

Additive Interactions of Maternal Prepregnancy BMI and Breast‐feeding on Childhood Overweight

Objective: To examine the interactions of maternal prepregnancy BMI and breast‐feeding on the risk of overweight among children 2 to 14 years of age. Research Methods and Procedures: The 1996 National Longitudinal Survey of Youth, Child and Young Adult data in the United States were analyzed (n = 2636). The weighted sample represented 51.3% boys, 78.0% whites, 15.0% blacks, and 7.0% Hispanics. Childhood overweight was defined as BMI ≥95th percentile for age and sex. Maternal prepregnancy obesity was determined as BMI ≥30 kg/m². The duration of breast‐feeding was measured as the weeks of age from birth when breast‐feeding ended. Results: After adjusting for potential confounders, children whose mothers were obese before pregnancy were at a greater risk of becoming overweight [adjusted odds ratio (OR), 4.1; 95% confidence interval (CI), 2.6, 6.4] than children whose mothers had normal BMI (<25 kg/m²; p < 0.001 for linear trend). Breast‐feeding for ≥4 months was associated with a lower risk of childhood overweight (OR, 0.6; 95% CI, 0.4, 1.0; p = 0.06 for linear trend). The additive interaction between maternal prepregnancy obesity and lack of breast‐feeding was detected (p < 0.05), such that children whose mothers were obese and who were never breast‐fed had the greatest risk of becoming overweight (OR, 6.1; 95% CI, 2.9, 13.1). Discussion: The combination of maternal prepregnancy obesity and lack of breast‐feeding may be associated with a greater risk of childhood overweight. Special attention may be needed for children with obese mothers and lack of breast‐feeding in developing childhood obesity intervention programs.     

The Role of Physical Activity in Harm Reduction among Betel Quid Chewers from a Prospective Cohort of 419,378 Individuals

ObjectiveTo assess the benefits of regular exercise in reducing harms associated with betel quid (BQ) chewing.MethodsThe study cohort, 419,378 individuals, participated in a medical screening program between 1994 and 2008, with 38,324 male and 1,495 female chewers, who consumed 5–15 quids of BQ a day. Physical activity of each individual, based on “MET-hour/week”, was classified as “inactive” or “active”, where activity started from a daily 15 minutes/day or more of brisk walking (≥3.75 MET-hour/week). Hazard ratios for mortality and remaining years in life expectancy were calculated.ResultsNearly one fifth (18.7%) of men, but only 0.7% of women were chewers. Chewers had a 10-fold increase in oral cancer risk; and a 2-3-fold increase in mortality from lung, esophagus and liver cancer, cardiovascular disease, and diabetes, with doubling of all-cause mortality. More than half of chewers were physically inactive (59%). Physical activity was beneficial for chewers, with a reduction of all-cause mortality by 19%. Inactive chewers had their lifespan shortened by 6.3 years, compared to non-chewers, but being active, chewers improved their health by gaining 2.5 years. The improvement, however, fell short of offsetting the harms from chewing.ConclusionsChewers had serious health consequences, but being physically active, chewers could mitigate some of these adverse effects, and extend life expectancy by 2.5 years and reduce mortality by one fifth. Encouraging exercise, in addition to quitting chewing, remains the best advice for 1.5 million chewers in Taiwan.
