Socioeconomic position in childhood and adulthood and insulin resistance: cross sectional survey using data from British women's heart and health study

ObjectiveTo assess the associations between childhood and adulthood social class and insulin resistance.DesignCross sectional survey.Setting23 towns across England, Scotland, and Wales.Participants4286 women aged 60-79 years.ResultsBelonging to manual social classes in childhood and in adulthood was independently associated with increased insulin resistance, dyslipidaemia, and general obesity. The association between childhood social class and insulin resistance was stronger than that for adult social class. The effect, on insulin resistance and other risk factors, of belonging to a manual social class at either stage in the life course was cumulative, with no evidence of an interaction between childhood and adult social class. Women who were in manual social classes in childhood remained at increased risk of insulin resistance, dyslipidaemia, and obesity—even if they moved into non-manual social classes in adulthood—compared with women who were in non-manual social classes at both stages.ConclusionsAdverse social circumstances in childhood, as well as adulthood, are strongly and independently associated with increased risk of insulin resistance and other metabolic risk factors.

What is already known on this topic

Poor childhood social circumstances are, independently of adult social circumstances, associated with increased cardiovascular disease riskThey are associated with some components of the insulin resistance syndrome, and adverse childhood environmental factors, possibly poor nutrition, may lead to insulin resistance and to adult cardiovascular diseaseEvidence on the association between childhood social circumstances and insulin resistance in adulthood, and between childhood social circumstances and cardiovascular disease risk factors in women, is scarce

What this study adds

Belonging to manual social classes in childhood and in adulthood is independently associated with increased insulin resistance, dyslipidaemia, and obesity in older womenWomen who were in manual social classes in childhood remained at increased risk of insulin resistance, dyslipidaemia, and obesity, even if they had moved into non-manual social classes in adulthood     

Correlates of Adult Binge Drinking: Evidence from a British Cohort

Objective

To investigate whether parental social class and cognitive ability in childhood, as well as social and psychological factors, particularly personality traits, are independently associated with binge drinking in 50 year old adults assessed in a longitudinal birth cohort study.

Method

17,415 babies born in Great Britain in 1958 and followed up at 11, 33, and 50 years of age. Their binge drinking alcohol abuse at aged 50 was the outcome measure.

Results

6,478 participants with data on parental social class, childhood cognitive ability, educational qualifications at age 33, personality traits, psychological distress, occupational levels, and alcohol consumption (all measured at age 50) were included in the study. Using logistic regression analyses, results showed that parental social class, childhood intelligence, educational qualifications, occupational levels, personality traits (Extraversion and Disagreeableness), as well as psychological distress, were all significantly and independently associated with adult excessive alcohol use. Men tended to binge drink more than women (22% in men and 9.8% in women).

Conclusion

Both social and psychological factors influence adult excessive alcohol consumption. Personality traits play a more important role than previously understood. There appears to be a distinction between the frequency and dose level of alcohol consumption.     

Improving the health behaviours of elderly people: randomised controlled trial of a general practice education programme

ObjectivesTo establish the effect of an educational intervention for general practitioners on the health behaviours and wellbeing of elderly patients.DesignRandomised controlled trial with 1 year follow up.SettingMetropolitan general practices in Melbourne, Australia.Subjects42 general practitioners and 267 of their patients aged over 65 years.InterventionEducational and clinical practice audit programme for general practitioners on health promotion for elderly people.ResultsPatients in the intervention group had increased (a) walking by an average of 88 minutes per fortnight, (b) frequency of pleasurable activities, and (c) self rated health compared with the control group. No change was seen in drug usage, rate of influenza vaccination, functional status, or psychological wellbeing as a result of the intervention. Extrapolations of the known effect of these changes in behaviour suggest mortality could be reduced by 22% if activity was sustained for 5 years.ConclusionsEducation of the general practitioners had a positive effect on health outcomes of their elderly patients. General practitioners may have considerable public health impact in promotion of health for elderly patients.

Key messages

• Few educational interventions for doctors have shown benefit to the health of patients
• Elderly people were identified in the UK health initiatives as in need of additional attention, and levels of health protective behaviours were low in community surveys
• A multifaceted educational intervention for general practitioners was effective in improving walking behaviour, self rated health status, and the frequency of social contacts in elderly patients
• General practitioners are effective in improving health and health behaviours in their elderly patients

     

DRD4-exonIII-VNTR moderates the effect of childhood adversities on emotional resilience in young-adults

Most individuals successfully maintain psychological well-being even when exposed to trauma or adversity. Emotional resilience or the ability to thrive in the face of adversity is determined by complex interactions between genetic makeup, previous exposure to stress, personality, coping style, availability of social support, etc. Recent studies have demonstrated that childhood trauma diminishes resilience in adults and affects mental health. The Dopamine receptor D4 (DRD4) exon III variable number tandem repeat (VNTR) polymorphism was reported to moderate the impact of adverse childhood environment on behaviour, mood and other health-related outcomes. In this study we investigated whether DRD4-exIII-VNTR genotype moderates the effect of childhood adversities (CA) on resilience. In a representative population sample (n = 1148) aged 30–34 years, we observed an interactive effect of DRD4 genotype and CA (β = 0.132; p = 0.003) on resilience despite no main effect of the genotype when effects of age, gender and education were controlled for. The 7-repeat allele appears to protect against the adverse effect of CA since the decline in resilience associated with increased adversity was evident only in individuals without the 7-repeat allele. Resilience was also significantly associated with approach-/avoidance-related personality measures (behavioural inhibition/activation system; BIS/BAS) measures and an interactive effect of DRD4-exIII-VNTR genotype and CA on BAS was observed. Hence it is possible that approach-related personality traits could be mediating the effect of the DRD4 gene and childhood environment interaction on resilience such that when stressors are present, the 7-repeat allele influences the development of personality in a way that provides protection against adverse outcomes.     

Psychological health and religious coping of Ghanaian women with infertility

Background

Infertility has been shown to have considerable psychological effects on the well-being of couples, especially women. Religion has been found as a resource used by infertile women to cope with their distress. Little research has examined the influence of religious coping on psychological distress among infertile women in Ghana. This study examines the relationship between positive and negative religious coping and psychological health for women with infertility problems in Ghana.

Methods

One hundred and fifty married women who were receiving assisted reproduction care in two specialized clinics were recruited for this study. Participants were administered with the Brief Symptom Inventory and Brief Religious Coping Scale to assess psychological health associated with infertility and religious coping respectively. A hierarchical regression was performed to examine the relative contribution of the domains of psychological health (i.e. somatization, anxiety and depression) in predicting negative religious coping and positive religious.

Results

The results showed that negative religious coping was significant and positively correlated with somatization, depression and anxiety. Furthermore, a positive relationship also existed between positive religious coping and somatization and anxiety but not depression. After controlling for age and duration of infertility, somatization and anxiety predicted positive religious coping whilst all the domains of psychological health (somatization, anxiety and depression) precited negative religious coping.

Conclusions

This study expanded on the existing literature by examining positive and negative religious coping with psychological distress associated with infertility for women. These results underscore the need for health professionals providing therapies for women with infertility to acknowledge and consider their religious beliefs as this influences their mental health.

     

Ecological study of social fragmentation,poverty, and suicide

ObjectivesTo investigate the association between suicide and area based measures of deprivation and social fragmentation.DesignEcological study.Setting633 parliamentary constituencies of Great Britain as defined in 1991.ResultsMortality from suicide and all other causes increased with increasing Townsend deprivation score, social fragmentation score, and abstention from voting in all age and sex groups. Suicide mortality was most strongly related to social fragmentation, whereas deaths from other causes were more closely associated with Townsend score. Constituencies with absolute increases in social fragmentation and Townsend scores between 1981 and 1991 tended to have greater increases in suicide rates over the same period. The relation between change in social fragmentation and suicide was largely independent of Townsend score, whereas the association with Townsend score was generally reduced after adjustment for social fragmentation.ConclusionsSuicide rates are more strongly associated with measures of social fragmentation than with poverty at a constituency level.

Key messages

• Place of residence may affect health, and mortality from most common diseases tends to be higher in areas characterised by low socioeconomic position
• Research dating back over 100 years suggests that social fragmentation may influencesuicide
• In the 1980s and 1990s, parliamentary constituencies with high levels of social fragmentation had high rates of suicide, independent of deprivation
• Constituencies with the greatest increases in social fragmentation between 1981 and 1991 also had the greatest increases in suicide rates over the same period
• Any targeting of suicide prevention may be more effective if aimed at socially fragmented rather than deprived areas

Bullying behaviour and psychosocial health among school students in New South Wales,Australia: cross sectional survey

ObjectivesTo examine the prevalence of bullying behaviours in schoolchildren and the association of bullying with psychological and psychosomatic health.DesignCross sectional survey.SettingGovernment and non-government schools in New South Wales, Australia.Participants3918 schoolchildren attending year 6 (mean age 11.88 years), year 8 (13.96), and year 10 (15.97) classes from 115 schools.ResultsAlmost a quarter of students (23.7%) bullied other students, 12.7% were bullied, 21.5% were both bullied and bullied others on one or more occasions in the last term of school, and 42.4% were neither bullied nor bullied others. More boys than girls reported bullying others and being victims of bullying. Bullying behaviour was associated with increased psychosomatic symptoms. Bullies tended to be unhappy with school; students who were bullied tended to like school and to feel alone. Students who both bullied and were bullied had the greatest number of psychological and psychosomatic symptoms.ConclusionsBeing bullied seems to be widespread in schools in New South Wales and is associated with increased psychosomatic symptoms and poor mental health. Health practitioners evaluating students with common psychological and psychosomatic symptoms should consider bullying and the student’s school environment as potential causes.

Key messages

• Bullying behaviour occurs in schools worldwide and is likely to be associated with poor health in schoolchildren
• Research into bullying has been mainly focused on victims but there are other categories of bullying that deserve attention
• At least three out of five students experienced or participated in bullying in schools in New South Wales, Australia
• The psychosocial and psychosomatic health of the students varied according to their bullying status

ObjectivesTo identify whether psychiatric disturbance in parentally bereaved children and surviving parents is related to service provision.DesignProspective case-control study.SettingTwo adjacent outer London health authorities. Participants45 bereaved families with children aged 2 to 16 years.ResultsParentally bereaved children and surviving parents showed higher than expected levels of psychiatric difficulties. Boys were more affected than girls, and bereaved mothers had more mental health difficulties than bereaved fathers. Levels of psychiatric disturbance in children were higher when parents showed probable psychiatric disorder. Service provision related to the age of the children and the manner of parental death. Children under 5 years of age were less likely to be offered services than older children even though their parents desired it. Children were significantly more likely to be offered services when the parent had committed suicide or when the death was expected. Children least likely to receive service support were those who were not in touch with services before parental death.ConclusionsService provision was not significantly related to parental wishes or to level of psychiatric disturbance in parents or children. There is a role for general practitioners and primary care workers in identifying psychologically distressed surviving parents whose children may be psychiatrically disturbed, and referring them to appropriate services.

Key messages

• Parentally bereaved children show high levels of psychological disturbance, with boys being more vulnerable than girls
• Surviving mothers show more psychiatric morbidity than surviving fathers
• Psychological distress in bereaved parents is associated with psychological difficulties in their children
• Service provision for bereaved children is not determined by mental health difficulties in either parents or children, or by parental wishes; it is influenced only by the manner of parental death and the age of the child
• The mismatch between need and service provision indicates a role for general practitioners and primary care workers in identifying distressed or disturbed families in need of public or voluntary service help

     

The influence of early conditions on health status among elderly Puerto Ricans

Abstract

The demographic origins of aging in Puerto Rican and other Latin American and Caribbean (LAC) countries may have important implications for the profile of health status and mortality of elderly people. For this article we tested a general conjecture about the relation between early childhood conditions and adult health status among Puerto Rican elderly using a rich data set recently collected through an island‐wide survey (N=4,293). We examined the association between markers of early nutritional status, self‐reports of health and on socioeconomic conditions during early childhood, and the prevalence of 3 conditions during adult ages: obesity, diabetes, and cardiovascular diseases. Although we found that obesity and diabetes are associated with markers of early malnutrition, that heart disease is associated with early deprivations and selected early childhood conditions, the evidence we were able to tease out from the data provides only fragile support for the conjecture.     

The Association between Maltreatment in Childhood and Pre-Pregnancy Obesity in Women Attending an Antenatal Clinic in Australia

Introduction

Obesity in pregnancy is associated with increased risk of complications and adverse outcomes in mother and child. Childhood adverse experiences are known to have numerous negative physical and emotional sequelae. We aimed to examine if exposure to abuse and/or neglect in childhood increased the likelihood of pre-pregnancy obesity.

Methods

Demographic and clinical data including weight, height, mental health as measured by the General Health Questionnaire and exposure to childhood trauma as measured by the childhood trauma questionnaire was collected from 239 women attending antenatal care at an Australian tertiary hospital.

Results

More than one quarter of women were obese prior to pregnancy and approximately 20% of women self reported experiencing moderate to severe physical, sexual or emotional abuse. Almost 60% of women scored in the clinical range on the GHQ. Pre-pregnancy obesity in women attending antenatal care was associated with a self-reported history of emotional or physical abuse with those exposed to moderate or severe emotional or physical abuse having increased odds of being obese prior to pregnancy (O.R. and 95% CI: 2.40; 1.19–4.84 and 2.38; 1.18–4.79 respectively). There was no significant association between other forms of childhood maltreatment, demographic or current mental health status and pre-pregnancy obesity.

Conclusions

The high rates of obesity, mental health problems and self reported childhood maltreatment in the Australian antenatal population are serious public health concerns due to the extra health risks conferred on mother and offspring. Exposure to physical or emotional abuse during childhood increases the likelihood of obesity in women attending antenatal care. Further research is required to determine reasons for this association.     

Depression,Social Support,and Coping Styles among Pregnant Women after the Lushan Earthquake in Ya’an,China

Aim

The aim of this study is to assess the depression of pregnant women in the aftermath of an earthquake, and to identify the social support that they obtained, their coping styles and socio-demographic factors associated with depression.

Methods

A total of 128 pregnant women from three hospitals in the epicenter area were recruited immediately after the Ya’an earthquake. Their depression was investigated using the Edinburgh Postnatal Depression Scale (EPDS) with a cutoff score of 14; the social support that they obtained was measured using the Social Support Questionnaire; and their coping styles were assessed using the Coping Styles Questionnaire.

Results

Immediately after the earthquake, the incidence rate of depression in pregnant women was 35.2%, higher than that of the general pregnant population (7%-14%). The EPDS scores were significantly correlated with gestation age at the time of the earthquake, objective support, subjective support, use of support, negative coping style, and positive coping style. The regression analysis indicated that risk factors of prenatal depression include the number of children, relatives wounded, subjective support, and coping styles. A further analysis of the interaction between social support and two types of coping styles with depression showed that there was interaction effect between subjective social support and positive coping styles in relation to EPDS scores. There was an inverse relationship between low EPDS scores and positive coping styles and high social support, and vice versa.

Conclusion

The timing of the occurrence of the earthquake may not necessarily affect the progress of the illness and recovery from depression, and psychological intervention could be conducted in the immediate aftermath after the earthquake. The impact of coping styles on prenatal depression appeared to be linked with social support. Helping pregnant women to adopt positive coping styles with good social support after a recent major earthquake, which is a stressor, may reduce their chances of developing prenatal depression.     

Population based study of social and productive activities as predictors of survival among elderly Americans

ObjectivesTo examine any association between social, productive, and physical activity and 13 year survival in older people. DesignProspective cohort study with annual mortality follow up. Activity and other measures were assessed by structured interviews at baseline in the participants’ homes. Proportional hazards models were used to model survival from time of initial interview.SettingCity of New Haven, Connecticut, United States.Participants2761 men and women from a random population sample of 2812 people aged 65 and older.ResultsAll three types of activity were independently associated with survival after age, sex, race/ethnicity, marital status, income, body mass index, smoking, functional disability, and history of cancer, diabetes, stroke, and myocardial infarction were controlled for.ConclusionsSocial and productive activities that involve little or no enhancement of fitness lower the risk of all cause mortality as much as fitness activities do. This suggests that in addition to increased cardiopulmonary fitness, activity may confer survival benefits through psychosocial pathways. Social and productive activities that require less physical exertion may complement exercise programmes and may constitute alternative interventions for frail elderly people.

Key messages

• Little is known about predictors of survival among elderly people
• Physical activity is clearly good for health, but the potential benefits of social activities have not been studied
• Social and productive activities are as effective as fitness activities in lowering the risk of death
• Enhanced social activities may help to increase the quality and length of life

     

What Are Lay Theories of Social Class?

Numerous studies have documented the effects of social class on psychological and behavioral variables. However, lay beliefs about how social class affects these dimensions have not been systematically tested. Studies 1 and 2 assessed lay beliefs about the association between social class and 8 variables (including psychological and behavioral tendencies and cognitive ability). Study 3 assessed lay beliefs about the Big five personality traits and social class, and study 4 reframed the 8 variables from study 1 in opposite terms and yielded similar results. Study 5 contained the variables framed as in both studies 1 and 4, and replicated those results suggesting that framing effects were not responsible for the effects observed. Interestingly, for the most part lay beliefs about social class did not differ as a function of participants’ own social class. In general people held relatively accurate and consistent stereotypes about the relationship between social class and well-being, health, intelligence, and neuroticism. In contrast lay beliefs regarding social class and reasoning styles, as well as relational, social, and emotional tendencies were less consistent and coherent. This work suggests that on the whole people’s beliefs about social class are not particularly accurate, and further that in some domains there are contradictory stereotypes about the consequences of social class.     

Factors associated with caregiving burden and mental health conditions in caregivers of patients with anorexia nervosa in Japan

Background

There are no studies about the caregiving burdens in families of patients with eating disorders in Japan, and only limited studies on the role of caregivers’ stress coping, social support, and mental health. This study examines caregiving burdens, mental health conditions, and associated factors in caregivers of anorexia nervosa (AN) patients in Japan.

Methods

Seventy-nine principal caregivers (70 mothers, 5 fathers, 3 spouses and 1 grandmother; mean age 56.0?±?8.0 years) for outpatients with AN (all female; mean age 26.6?±?7.9 years; BMI 14.6?±?3.2 kg/m²) were evaluated using self-report questionnaires in a cross-sectional study. The questionnaires included caregiving burden (J-ZBI_8), mental health conditions (GHQ28), stress coping styles (CISS), social support (SNQ), severity of the patient’s symptoms from the family’s perspective (ABOS), and family functioning (GF-FAD). Clinical information about the patients was also obtained.

Results

Mean caregiving burden assessed by J-ZBI_8 score was 12.4?±?7.0 (SD). The total GHQ score was 31.6?±?13.7 (Likert scoring) and 9.2?±?7.0 (GHQ scoring). Of the respondents, 48 (60.7 %) indicated a high risk for mental health problems that exceeded the cutoff point of the GHQ. Significantly higher caregiving burden and poor mental health conditions were shown in the group who had contact with patients?>?6 h a day compared to the group with daily patient contact?<?3 h (F (2, 76)?=?3.19, p?=?0.047 and F (2, 76)?=?9.39, p?<?0.001, respectively). Stepwise multiple regression analysis indicated that the factors that significantly predicted the caregiving burden were severity of the patient’s symptoms from the family’s perspective (β?=?0.47, p?<?0.001) and Emotion-Oriented Coping (β?=?0.38, p?=?0.002) (R²?=?0.401), while predictors of mental health conditions were Emotion-Oriented Coping (β?=?0.522, p?<?0.001), Affective Support (β?=??0.419, p?<?0.001), and contact time with patient (β?=?0.201, p?=?0.042) (R²?=?0.602).

Conclusion

Caregivers of AN patients experienced heavy burdens and manifested poor mental health conditions. The severity of the patient’s symptoms from the family’s perspective and the greater use of emotion-oriented coping were associated with higher burdens. Greater use of emotion-oriented coping, less affective support and longer contact with patients were related to worse mental health conditions. Interventions to promote caregivers’ adaptive coping styles may help reduce their caregiving burden and improve their mental health.

     

Socioeconomic inequalities in prevalence and development of multimorbidity across adulthood: A longitudinal analysis of the MRC 1946 National Survey of Health and Development in the UK

BackgroundWe aimed to estimate multimorbidity trajectories and quantify socioeconomic inequalities based on childhood and adulthood socioeconomic position (SEP) in the risks and rates of multimorbidity accumulation across adulthood.Methods and findingsParticipants from the UK 1946 National Survey of Health and Development (NSHD) birth cohort study who attended the age 36 years assessment in 1982 and any one of the follow-up assessments at ages 43, 53, 63, and 69 years (N = 3,723, 51% males). Information on 18 health conditions was based on a combination of self-report, biomarkers, health records, and prescribed medications. We estimated multimorbidity trajectories and delineated socioeconomic inequalities (based on childhood and adulthood social class and highest education) in multimorbidity at each age and in longitudinal trajectories.Multimorbidity increased with age (0.7 conditions at 36 years to 3.7 at 69 years). Multimorbidity accumulation was nonlinear, accelerating with age at the rate of 0.08 conditions/year (95% CI 0.07 to 0.09, p < 0.001) at 36 to 43 years to 0.19 conditions/year (95% CI 0.18 to 0.20, p < 0.001) at 63 to 69 years. At all ages, the most socioeconomically disadvantaged had 1.2 to 1.4 times greater number of conditions on average compared to the most advantaged. The most disadvantaged by each socioeconomic indicator experienced an additional 0.39 conditions (childhood social class), 0.83 (adult social class), and 1.08 conditions (adult education) at age 69 years, independent of all other socioeconomic indicators. Adverse adulthood SEP was associated with more rapid accumulation of multimorbidity, resulting in 0.49 excess conditions in partly/unskilled compared to professional/intermediate individuals between 63 and 69 years. Disadvantaged childhood social class, independently of adulthood SEP, was associated with accelerated multimorbidity trajectories from age 53 years onwards.Study limitations include that the NSHD cohort is composed of individuals of white European heritage only, and findings may not be generalizable to the non-white British population of the same generation and did not account for other important dimensions of SEP such as income and wealth.ConclusionsIn this study, we found that socioeconomically disadvantaged individuals have earlier onset and more rapid accumulation of multimorbidity resulting in widening inequalities into old age, with independent contributions from both childhood and adulthood SEP.

Factors Influencing Adult Physical Health after Controlling for Current Health Conditions: Evidence from a British Cohort

This study explored a longitudinal data set of 6875 British adults examining the effects of parental social status (measured at birth), cognitive ability (at age 11 yrs), personality traits, education and occupational attainment on physical health and functioning (all measured at age 50 yrs), after taking account of current health conditions (number of illness). Correlation analysis showed that parental social class, childhood cognitive ability, education and occupation, and two personality traits (Emotional Stability/Neuroticism, and Conscientiousness) were all significantly associated with adult physical health variables. Structural equation modelling showed that health conditions and personality traits were significantly, and inversely, associated with physical health (indicated by good daily physical functioning, relative absence of pain, perceived health, and low level of limitations at work due to physical health). Parental social status, childhood intelligence, educational and occupational attainment were all modestly, but significantly and directly, associated with adult physical health. The effect of childhood intelligence on adult physical health was, in part, mediated through Emotional Stability and Conscientiousness. After controlling for health conditions Emotional Stability was the strongest predictor of physical health. Implications and limitations are discussed.     

Pertussis vaccination and wheezing illnesses in young children: prospective cohort study. The Longitudinal Study of Pregnancy and Childhood Team

ObjectivesTo examine the relation between pertussis vaccination and the prevalence of wheezing illnesses in young children. DesignProspective cohort study.SettingThree former health districts comprising Avon Health Authority.Subjects9444 of 14 138 children enrolled in the Avon longitudinal study of pregnancy and childhood and for whom data on wheezing symptoms, vaccination status, and 15 environmental and biological variables were available.ResultsUnadjusted comparisons of the defined wheezing illnesses in vaccinated and non-vaccinated children showed no significant association between pertussis vaccination and any of the wheezing outcomes regardless of stratification for parental asthma or allergy. Wheeze was more common in non-vaccinated children at 18 months, and there was a tendency for late onset wheezing to be associated with non-vaccination in children whose parents did not have asthma, but this was not significant. After adjustment for environmental and biological variables, logistic regression analyses showed no significant increased relative risk for any of the wheezing outcomes in vaccinated children: early wheezing (0.99, 95% confidence interval 0.80 to 1.23), late onset wheezing (0.85, 0.69 to 1.05), persistent wheezing (0.91, 0.47 to 1.79), recurrent wheezing (0.96, 0.72 to 1.26), and intermittent wheezing (1.06, 0.81 to 1.37).ConclusionsNo evidence was found that pertussis vaccination increases the risk of wheezing illnesses in young children. Further follow up of this population with objective measurement of allergy and bronchial responsiveness is planned to confirm these observations.

Key messages

• Pertussis vaccination has been proposed as a risk factor for the development of asthma and atopy
• There was no evidence for increased wheezing illnesses in young children who were vaccinated against pertussis compared with non-vaccinated children
• Follow up studies of this population will help to further clarify the relation between early infections and vaccination and the development of atopic diseases, including asthma
• Large scale longitudinal studies beginning in pregnancy offer the opportunity to examine complex interactions between genetics and the environment in the cause of common childhood diseases

     

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
