Socioeconomic differentials in nutritional status of children in the states of West Bengal and Assam, India

Malnutrition among children is prevalent in almost all the states in India. This study assesses the extent and causes of malnutrition in two eastern Indian states with similar climates, namely West Bengal and Assam, using data from the National Family Health Survey 1998-99 (NFHS-2). The three indices of malnutrition taken for analysis are weight-for-height (WHZ), height-for-age (HAZ) and weight-for-age (WAZ). These are assumed to depend on birth order, preceding birth interval, parent's educational status, working status of the mother, mother's age at delivery of the children, source of drinking water, toilet facilities and standard of living of the household. Logistic regression was carried out separately for each of the three indices on the explanatory variables for both the states. It was found that not all variables are equally important in determining whether a baby is underweight, or suffering from acute or chronic malnutrition. Also, the importance of variables is not the same in the two states. It was observed that the coefficients associated with the variables in determining weight-for-height are not significant compared with those for weight-for-age and height-for-age.     

An analysis of childhood malnutrition in Kerala and Goa

Improved child health and survival are considered universal humanitarian goals. In this respect, understanding the nutritional status of children has far-reaching implications for the better development of future generations. The present study assessed, first, the nutritional status of children below 5 years using the three anthropometric measures weight-for-age, height-for-age and weight-for-height in two states of India, Kerala and Goa. Secondly, it examined the confounding factors that influence the nutritional status of children in these states. The NFHS-I data for Kerala and Goa were used. The results showed that the relative prevalence of underweight and wasting was high in Kerala, but the prevalence of stunting was medium. In Goa, on the other hand, the relative prevalence of wasting and underweight was very high, and that of stunting was high. Both socioeconomic and family planning variables were significantly associated with malnutrition in these states, but at varied levels. The study recommends more area-specific policies for the development of nutritional intervention programmes.     

Effect of undernutrition on deciduous tooth emergence among Rajput children of Shimla District of Himachal Pradesh, India

This article examines the influence of nutritional status on the emergence of deciduous dentition in a cross-sectional sample of 510 rural Rajput children from the Jubbal and Kotkhai Tehsils, Shimla District, Himachal Pradesh, India. The nutritional status of each child was evaluated using Z-scores of height/supine length-for-age (HAZ), weight-for-age (WAZ), and weight-for-height (WHZ). The effects of sex and side on deciduous dental emergence were not statistically significant. Partial correlation indicates that the number of emerged teeth (T) was more strongly correlated with height than with other anthropometric variables. In most age groups, the stunted boys and girls (HAZ <-2) had fewer emerged teeth than nonstunted age peers (HAZ >-2). The mean T in underweight children was also less than that of the normal children, with a few exceptions. The stunted children have a significantly greater likelihood of delayed emergence of deciduous dentition. Measures of linear growth status are more closely related to dental development than measures of growth in mass. The findings indicate that even moderate undernutrition can delay deciduous tooth emergence.     

Childhood malnutrition and growth in a rural area of Western Kenya

An anthropometric survey was carried out on 1,383 school students aged 5-17 years in Suba district (a rural area of western Kenya). Body size and proportion were computed from height, weight, sitting height, arm circumference, and skinfolds. The aim of the study was to evaluate patterns of growth and nutritional status of the Luo population by assessment of the prevalence and trends of malnutrition among children and adolescents. Very few age-groups show significant sex differences for height, body weight, and arm muscle area. However, there are several differences in skinfold thicknesses and arm circumference, always with higher mean values in girls. Analysis of the nutritional status (weight-for-age, height-for-age, and BMI-for-age) shows significant differences among the age-groups in both sexes. Boys present lower Z-scores than girls and there are higher percentages of malnourished subjects (stunted and underweight) among the males. The Luo data were compared with those of other African populations. Their body dimensions, nutritional status, and growth are similar to those of the other sub-Saharan samples. In conclusion, the Luo children are generally undernourished at the older ages: adolescents (11-16 years of age) show the most severe undernutrition and the highest percentages of undernourished subjects. In addition to the higher risk of undernutrition in teenagers, an emerging problem of over-nutrition is evident among the younger age-groups, with a higher prevalence in females. These findings are discussed in light of sexual dimorphism in sensitivity to adverse environmental conditions.     

Anthropometric indicators of nutritional status, socioeconomic factors and mortality in hospitalized children in Addis Ababa

The influence of some household and maternal variables on three anthropometric nutritional status indices of hospitalized children in Addis Ababa, Ethiopia, are examined. On admission, only 30% of these children can be classified as being of a normal overall nutritional status. There are no significant differences in weight-for-age of hospitalized children between those residing in Addis Ababa and those residing in the rural areas. Income and father's occupation appear to be the major household factors influencing the level of two of the three indices (weight-for-age and weight-for-height). Length of last closed birth interval and, to a lesser degree, maternal age appear to have significant effects on all three nutritional status indices. Upon admission to hospital, children who will in the end survive their hospital stay are on average nutritionally normal or in a mild state of malnutrition, whereas children who will die during their stay arrive in a moderate or severe state of malnutrition. The degree of malnutrition is positively related to the risk of mortality in respiratory disease patients.     

Female autonomy as a contributing factor to women's HIV-related knowledge and behaviour in three culturally contrasting States in India

Factors contributing to India's vulnerability to the AIDS epidemic include pervasive poverty, low levels of education and high gender stratification. This study uses data collected in the 1998-99 National Family Health Survey-2 (NFHS-2) to investigate the relationship between aspects of women's autonomy and four measures of HIV-related knowledge and behaviour--awareness and knowledge of HIV/AIDS, condom awareness and condom use--in three culturally contrasting states in India: Kerala (n=2884), Karnataka (n=4357) and Uttar Pradesh (n=8981). The NFHS-2 is a nationally representative survey of India, with a sampling scheme that was designed such that each state sample can be generalized back to represent ever-married women aged 15-49 living in the state. Kerala scores highest in the four health outcome measures, followed by Karnataka and then Uttar Pradesh, but condom use is lowest in Karnataka. Kerala also leads in the four dimensions of autonomy examined and in socio-demographic status, followed again by Karnataka and Uttar Pradesh. Despite these observed differences, in all three states, women with greater autonomy as measured by this study were more likely to be knowledgeable about AIDS and condoms and to use condoms, after controlling for socio-demographic factors. These results concur with other studies focusing on women's autonomy and health outcomes around the world, and point to the importance of incorporating a gender-based approach to AIDS prevention programmes in India.     

Growth and development of adolescent girls from the Segou Region of Mali (West Africa)

In Mali, adolescent girls face many physical stresses which, with a history of poor nutrition, can result in delayed growth and development. Despite the fact that adolescent girls encounter nutritional demands, most research in Mali has focused only on young children. This study examines anthropometric and reproductive data on 1,056 adolescent girls (aged 10-17 years) from the Segou Region of Mali. When compared to the reference population, the Malian girls exhibited poorer indicators of growth and development. Z-scores for height-for-age and weight-for-age were below 0 at all ages. Urban girls had better indicators of growth than rural girls. The body composition data show that the Malian girls have lower body fat than reference girls. Menarche was delayed by about 1.5 years compared to girls from the United States and Europe. Delayed growth and development may be due to many factors, including a history of undernutrition, poor socioeconomic status, and increased energy demands.     

A case-control study of maternal knowledge of malnutrition and health-care-seeking attitudes in rural South India.

INTRODUCTION: In India, approximately 20 percent of children under the age of four suffer from severe malnutrition, while half of all the children suffer from undernutrition. The contributions of knowledge and attitudes of nutrition-conscious behaviors of the mothers to childhood malnutrition has been unclear. The purpose of this study was to explore maternal knowledge of the causes of malnutrition, health-care-seeking attitudes and socioeconomic risk factors in relation to children''s nutritional status in rural south India. METHODS: A case-controlled study was conducted in a rural area in Tamil Nadu, India. Thirty-four cases and 34 controls were selected from the population of approximately 97,000 by using the local hospital''s list of young children. A case was defined as a mother of a severely malnourished child under four years of age. Severe malnutrition was defined as having less than 60 percent of expected median weight-for-age. A control had a well-nourished child and was matched by the location and the age of the child. Interviews obtained: (1) socioeconomic information on the family, (2) knowledge of the cause of malnutrition and (3) health-care-seeking attitudes for common childhood illnesses, including malnutrition. RESULTS: Poor nutritional status was associated with socioeconomic variables such as sex of the child and father''s occupation. Female gender (OR = 3.44, p = .02) and father''s occupation as a laborer (OR = 2.98, p = .05) were significant risk factors for severe malnutrition. The two groups showed a significant difference in nutrition-related knowledge of mild mixed malnutrition (OR = 2.62, p = .05). No significant difference was apparent in health-care-seeking attitudes. Based on their traditional beliefs, the mothers did not believe that medical care was an appropriate intervention for childhood illnesses such as malnutrition or measles. DISCUSSION: The results suggested that the gender of the child and socioeconomic factors were stronger risk factors for malnutrition than health-care availability and health-care-seeking attitudes. The father''s occupation was a more accurate indicator for malnutrition than household income. These results suggest a need for intensive nutritional programs targeted toward poor female children and their mothers.     

The height-for-age of Indian children

The height for age of children is used as an indicator of the prevalence of undernutrition, i.e., 'stunting'. This study uses unit-record data on over 20,000 rural children, from 16 states of India, to explain variations in their height-for-age. Previous studies of children's heights have focused exclusively on the mean of the distribution of heights-for-age using ordinary least squares (OLS) regression. Instead, this paper uses quantile regression--which analyses different parts of the height for age distribution--and permits a richer set of conclusions to be drawn. The analysis shows the importance of locating malnourished children in terms of their place in the distribution of nutritional outcomes and, then, studying the differential impact of the determining variables on outcomes for children in different locations of the distribution.     

Nutritional Status of Orphaned and Separated Children and Adolescents Living in Community and Institutional Environments in Uasin Gishu County,Kenya

Objective

To describe the nutritional status of orphaned and separated children and adolescents (OSCA) living in households in the community (HH), on the street, and those in institutional environments in western Kenya.

Methods

The study enrolled OSCA from 300 randomly selected households (HH), 19 Charitable Children’s Institutions (CCIs), and 100 street-involved children. Measures of malnutrition were standardized with Z-scores using World Health Organization criteria; Z-scores ≤-2 standard deviations (sd) were moderate-severe malnutrition. Data were analyzed using multivariable logistic regression adjusting for child age, sex, HIV status, whether the child had been hospitalized in the previous year, time living with current guardian, and intra-household clustering for adequacy of diet and moderate-severe malnutrition.

Results

Included are data from 2862 participants (1337 in CCI’s, 1425 in HH’s, and 100 street youth). The population was 46% female with median age at enrolment of 11.1 years. Only 4.4% of households and institutions reported household food security; 93% of children in HH reported an adequate diet vs. 95% in CCI’s and 99% among street youth. After adjustment, OSCA in HH were less likely to have an adequate diet compared to those in CCI’s (AOR 0.4, 95% CI 0.2–1.0). After adjustment, there were no differences between the categories of children on weight-for-age, weight-for-height, or BMI-for-age. Children living in HH (AOR 2.6, 95% CI: 2.0–3.4) and street youth (AOR: 5.9, 95% CI: 3.6–9.5) were more likely than children in CCI’s to be low height-for-age.

Conclusion

OSCA in HH are less likely to have an adequate diet compared to children in CCI’s. They and street children are more likely to be moderately-severely low height-for-age compared to children in CCI’s, suggesting chronic malnutrition among them.     

Physical growth and nutritional status of Tsimane' Amerindian children of lowland Bolivia

This study examines patterns of growth and nutritional status of indigenous Tsimane' children under 9 years of age (n = 199 boys and 210 girls), based on a cross-sectional sample from 58 villages from the Beni Deparment of lowland Bolivia. Compared with US children, Tsimane' children are quite short, with linear growth tracking at or below the US 5th centile in both sexes.

Catching up from early nutritional deficits? Evidence from rural Ethiopia

We examine the nutritional status of a cohort of poor Ethiopian children and their patterns of catch-up growth in height-for-age between three key development stages: age one, five and eight. We use ordinary least squares (within community) and instrumental variables analysis. During the earliest period, we find that nutritional catch-up patterns vary substantially across socioeconomic groups: average catch-up growth in height-for-age is almost perfect among children in relatively better-off households, while among the poorer children, relative height is more persistent. Between five and eight years of age, however, we find near-perfect persistence and no evidence of heterogeneity in catch-up growth. Our findings suggest that household wealth, and in particular access to services, can lead to substantial catch-up growth early on in life. However, for our sample, the window of opportunity to catch up appears to close as early as the age of five.     

Growth and nutritional status of male adolescent laborers in Ankara, Turkey

Undernutrition, pathogenic agents, and poor living conditions are of primary importance in the evaluation of adverse environmental conditions' effects on human growth; but child labor (an equally significant factor, especially in underdeveloped countries) is generally overlooked or ignored. The aim of this study is to focus on this subject and clarify the effects of labor on the physical growth and nutritional status of child and adolescent laborers. In this study, the height and weight of 532 male adolescent laborers aged 13.5-18.5 years and their non-laboring peers (n = 451) (the control group) were measured by standard anthropometric techniques and equipment. The individuals of both groups come from lower socioeconomic strata and share similar living conditions. Data were transformed to z-scores, using the US Center for Disease Control and Prevention's 2000 growth charts. The analyses show that the z-scores for height-for-age, weight-for-age, and body mass index (BMI)-for-age were negative in both groups. The z-scores of laborers' height-for-age and weight-for-age values lie below the controls', but there is no significant difference between the two groups' BMI-for-age scores. In the laboring group, the percentages of stunting (-2 SD of height-for-age), underweight (-2 SD of weight-for-age), and wasting (-2 SD of BMI-for-age) were 14.3, 2.6, and 0.2, respectively. These values suggest that malnutrition is not a common problem among adolescent laborers living in Ankara; but laboring is an important cause of faltering in growth, particularly in linear growth, in less or underdeveloped economic environments.     

Heterogeneity in predictive power of early childhood nutritional indicators for mid-childhood outcomes: Evidence from Vietnam

We utilize longitudinal data on nearly 1800 children in Vietnam to study the predictive power of alternative measures of early childhood undernutrition for outcomes at age eight years: weight-for-age (WAZ8), height-for-age (HAZ8), and education (reading, math and receptive vocabulary). We apply two-stage procedures to derive unpredicted weight gain and height growth in the first year of life. Our estimates show that a standard deviation (SD) increase in birth weight is associated with an increase of 0.14 (standard error [SE]: 0.03) in WAZ8 and 0.12 (SE: 0.02) in HAZ8. These are significantly lower than the corresponding figures for a SD increase in unpredicted weight gain: 0.51 (SE: 0.02) and 0.33 (SE: 0.02).The heterogeneity of the predictive power of early childhood nutrition indicators for mid-childhood outcomes reflects both life-cycle considerations (prenatal versus postnatal) and the choice of anthropometric measure (height versus weight). Even though all the nutritional indicators that involve postnatal nutritional status are important predictors for all the mid-childhood outcomes, there are some important differences between the indicators on weight and height. The magnitude of associations with the outcomes is one aspect of the heterogeneity. More importantly there is a component of height-for-age z-score (at age 12 months) that adds predictive power for all the mid-childhood outcomes beyond that of birth weight and weight gain in the first year of life.     

Prevalence and causes of chronic energy deficiency and obesity in Indian women

We investigate the nutritional status of women in India and its relation to the prevalence of chronic energy deficiency (CED) and obesity. To do this, we have used the data from the Indian National Family Health Survey, 1998-1999, on body mass index (BMI) of ever-married women, ages 15-49 years, along with several socioeconomic factors, such as level of education, religion or caste, occupational status, and standard of living index. The study was based on 81,712 women from 26 states and 6 zones, which were grouped according to geographic proximity of the states of India. A multiple linear regression analysis was done to see the relation between nutritional status of women and different socioeconomic factors. The data reveal that the prevalences of CED, overweight, and obesity in India are 31.2%, 9.4%, and 2.6%, respectively. The incidences of CED and obesity are negatively related. The prevalence of CED is the lowest in Arunachal Pradesh and highest in Orissa. Punjab has the highest prevalence of obesity, and Bihar has the lowest. For the zonewise distribution the Northeast zone has the lowest degree of prevalence of CED and the East zone is at the bottom of the list with the highest degree of malnutrition. We also found that the nutritional status of women goes together with the enhancement of their educational status, standard of living, and so on. There are also significant differences between rural and urban sectors and among castes, religions, and occupations. Furthermore, regression analysis shows that all the socioeconomic variables considered here significantly affect BMI in Indian women.     

Tall claims: Mortality selection and the height of children in India

Data from three rounds of nationally representative health surveys in India (1992/93, 1998/99 and 2005/06) are used to assess the impact of selective mortality on children's anthropometrics. The nutritional status of the child population was simulated under the counterfactual scenario that all children who died in the first three years of life were alive at the time of measurement. The simulations demonstrate that the difference in anthropometrics due to selective mortality would be large only if there were very large differences in anthropometrics between the children who died and those who survived. Differences of this size are not substantiated by the research on the degree of association between mortality and malnutrition. The study shows that although mortality risk is higher among malnourished children, selective mortality has only a minor impact on the measured nutritional status of children stratified by gender.     

The effects of prenatal exposure to Ramadan on stature during childhood and adolescence: Evidence from the Indonesian Family Life Survey

Many pregnant Muslim women fast during the Muslim holy month of Ramadan. A number of studies have reported negative life outcomes in adulthood for children who were prenatally exposed to Ramadan. However, other studies document minimal to no impact on neonatal indicators. Using data from the Indonesian Family Life Survey consisting of 45,246 observations of 21,723 children born to 9771 mothers, we contribute to the current discussion on prenatal exposure to Ramadan by examining the effects on stature (height-for-age Z-scores, weight-for-age Z-scores, and body-mass-index-for-age Z-scores: HAZ, WAZ, and BAZ, respectively) from early childhood to late adolescence (0–19 years of age). We introduce an objective mother’s religiosity indicator to improve the intention-to-treat estimations. Children were classified into three groups based on their mother’s religion-religiosity: religious Muslims, less-religious Muslims, and non-Muslims. Using cluster-robust mother fixed-effects, we found negative effects on stature for children born to religious Muslim mothers. The effects were age-dependent and timing-sensitive. For example, children born to religious Muslim mothers were shorter in late adolescence (15–19 years of age) compared to their unexposed siblings if they were prenatally exposed in the first trimester of pregnancy (HAZ difference = −0.105 SD; p-val. <0.05). Interestingly, we found positive effects on stature for exposed less-religious Muslim children that peak in early adolescence (10–14 years of age) and negative effects on stature for exposed non-Muslim children that occur only in early childhood (0–4 years of age). We nuance our discussion of health and socioeconomic factors to explain these surprising results.     

Significant effects of birth-related biological factors on pre-adolescent nutritional status among rural Sundanese in West Java, Indonesia

The Sundanese inhabiting West Java, the second largest ethnic group in Indonesia, are characterized by a high prevalence of child malnutrition, together with high fertility. Based on an anthropometric measurement and interview survey of 310 children aged 5-12 years in a rural Sundanese village, this study examined the relative significance of the effects of eight biological, eight socioeconomic status (SES) and four health behavioural factors on their Z scores for height-for-age (HAZ) and weight-for-age (WAZ) in particular. Three biological factors, i.e. birth interval, birth weight and mother's body weight, and one SES factor, i.e. mother's occupation, were selected as the predictors of the two Z scores by regression analysis, indicating more significant effects of the biological factors than the other factors. This pattern is judged to occur in less-developed and high-fertility populations. Since these two Z scores were worse in the subject children than in the under-5-year-old children from the same village, more attention should be paid to the long-lasting effects of birth-related biological factors up to pre-adolescent ages, as an insufficient nutritional status tends to damage growth and health in adolescence and adulthood.     

Population policy,family size and child malnutrition in Vietnam – Testing the trade-off between child quantity and quality from a child nutrition perspective

This paper estimates the quantity-quality (QQ) trade-off of children from a child nutrition perspective, using data on 2000 children born in 2001–2002 from the Young Lives project in Vietnam. Using the sex of the first-born in the family as an instrumental variable for family size, we found that having an additional sibling lowers a 5-year-old Vietnamese child’s height-for-age and weight-for-age Z scores by 0.3 and 0.26 standard deviations (SDs), respectively. This finding is robust to a series of checks, providing strong evidence of the quantity-quality trade-off of children. In more policy-relevant terms, our estimates suggest that the violation of Vietnam’s Two-Child policy (i.e., having more than two children) may have caused reductions in 5-year-old Vietnamese children’s height-for-age and weight-for-age by, respectively, 0.49 and 0.57 SDs.     

The effect of the health care supply environment on children's nutritional status in rural Nepal

This article examines the effect of access to health infrastructure, personnel and services on children's nutritional status in rural Nepal. Data for the study come from the 1996 Nepal Living Standards Survey, which includes individual- and household-level information on children's nutritional status and its environmental and socioeconomic determinants, and community-level information on the availability of health care infrastructure, personnel and services. The study uses a structural modelling approach to assess the relative contributions of the health care supply environment on children's anthropometric status via the pathway of maternal and child health (MCH) service use. The findings suggest that improvements in the availability of outreach clinics and the structural quality of the closest public facility would be expected to have statistically significant and large effects on the use of MCH services, and that increases in MCH service use would have a statistically significant impact on weight-for-age, but not weight-for-height or height-for-age. The overall impact of the heath care supply environment on nutritional status is assessed through a series of policy simulations.
