Prevalence of under-nutrition and its correlates among under 3 year-old children in rural areas of Andhra Pradesh, India

Association of breastfeeding with undernutrition among children under 5 years of age in developing countries: A systematic review and meta-analysis

OBJECTIVE

This meta-analysis was conducted to examine the association between breastfeeding and undernutrition among children under 5 years of age in developing countries.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A comprehensive literature search was conducted of datasets from Embase, CINHAL, PubMed, Cochrane Library, and Indonesian databases to include eligible studies. Comprehensive Meta-Analysis 3.0 statistical software was used to perform data entry and data analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were extracted from each study or were calculated based on the reported number of cases and controls in each study. Random-effects models or fixed-effects models were used to demonstrate overall risk estimates. A moderator analysis was conducted to examine possible moderators explaining the heterogeneity across studies.

FINDINGS

In total, 33 studies were included which examined the association of breastfeeding with undernutrition. A random-effects model showed that breastfeeding had inverse correlations with overall undernutrition (OR = 0.82, 95% CI = 0.68, 0.99) and the stunting type of undernutrition (OR = 0.73, 95% CI = 0.55, 0.95). A moderator analysis showed that studies which included exclusive breastfeeding and unclear birth weights had low risks of overall undernutrition (p < 0.05). Moreover, studies which included exclusive breastfeeding and adopted a case-control study design exhibited a low risk of the stunting type of undernutrition (p < 0.05).

CONCLUSIONS

Providing breastfeeding or exclusive breastfeeding can benefit children under 5 years of age in developing countries reduce overall undernutrition and the stunting type of undernutrition.

CLINICAL RELEVANCE

Healthcare professionals should develop and implement suitable strategies to increase awareness regarding the importance of breastfeeding and enhance breastfeeding and exclusive breastfeeding adherence.

Exploring the relationships between wasting and stunting among a cohort of children under two years of age in Niger

BACKGROUND

Wasting and stunting, physical growth manifestations of child undernutrition, have historically been considered separately with distinct interventions at the program, policy, and financing levels despite similar risk factors, overlapping burdens and multiplicative risk of death when the conditions are concurrent. The aim of this study was to elucidate shared risk factors and the temporal relationship between wasting and stunting among children under 2 years of age in rural Niger.

METHODS

From August 2014 to December 2019, anthropometric data were collected every 4 weeks from 6 to 8 weeks to 24 months of age for 6567 children comprising 139,529 visits in Madarounfa, Niger. Children were defined as wasted if they had a weight-for-length Z-score < - 2 and stunted if they had a length-for-age Z-score < - 2 using the 2006 World Health Organization child growth standards. Parental, child, and socioeconomic risk factors for wasting and stunting at 6 and 24 months of age and the relationship between episodes of wasting, stunting and concurrent wasting-stunting were assessed using general estimating equations.

RESULTS

Half of children (50%) were female, and 8.3% were born low birthweight (< 2500 g). Overall, at 24 months of age, 14% of children were wasted, 80% were stunted and 12% were concurrently wasted-stunted. We found that maternal short stature, male sex, and low birthweight were risk factors for wasting and stunting at 6 and 24 months, whereas higher maternal body mass index and household wealth were protective factors. Wasting at 6 and 24 months was predicted by a prior episodes of wasting, stunting, and concurrent wasting-stunting. Stunting at 6 and 24 months was similarly predicted by prior episodes of stunting and concurrent wasting-stunting at any prior age but only by prior episodes of wasting after 6 months of age.

CONCLUSIONS

These data support a complex and dynamic bi-directional relationship between wasting and stunting in young children in rural Niger and an important burden of concurrent wasting-stunting in this setting. Further research to better understand the inter-relationships and mechanisms between these two conditions is needed in order to develop and target interventions to promote child growth.

Risk factors for undernutrition in under-five children living in a migrant populated area of South Delhi

INTRODUCTION

Undernutrition is continuing to be a major public health problem in India. Moreover, India houses more than 30% of the world's stunted children aged under 5 years. There was a paucity of a community-based cross-sectional study on the nutrition of children aged under 5 years in urban Delhi. Therefore, we conducted this study to assess the prevalence of undernutrition and their associated factors in children aged under 5 years in urban South Delhi.

MATERIALS AND METHODS

A cross-sectional community-based study was conducted in the Mehrauli area of South Delhi with a semi-structured questionnaire. Systematic random sampling without replacement was implemented. Informed written consent was sought from the parents of participants. Questions were asked regarding demography and sociocultural factors of the participants. Anthropometry measurements were obtained. Underweight and stunting were defined using WHO child growth standards 2006.

RESULTS

A total of 520 participants in 695 houses were contacted and interviewed. Prevalence of underweight and stunting were 34.0% and 42.6%, respectively. Sociocultural factors, associated with underweight and stunting, found in current study were fathers' education (with both, P value < 0.05), mothers' education (with both, P value < 0.05), poverty status (with both, P value <0.05), overcrowding (stunting only, P value <0.05), fathers' alcohol abuse (with both, P value < 0.05) and exclusive breastfeeding for 6 months (stunting only, P value <0.05).

RESULTS

A total of 520 participants in 695 houses were contacted and interviewed. Prevalence of underweight and stunting were 34.0% and 42.6%, respectively. Sociocultural factors, associated with underweight and stunting, found in current study were fathers' education (with both, P value < 0.05), mothers' education (with both, P value < 0.05), poverty status (with both, P value <0.05), overcrowding (stunting only, P value <0.05), fathers' alcohol abuse (with both, P value < 0.05) and exclusive breastfeeding for 6 months (stunting only, P value <0.05).

CONCLUSIONS

There was a very high prevalence of underweight (34.0%) and stunting (42.6%) in children under 5 years age in Mehrauli.

Malnutrition in South Asia-A Critical Reappraisal

Malnutrition continues to be a major public health challenge especially in South Asian developing countries. The aim of the present review is to spotlight the magnitude of the prevalence of malnutrition and its dynamics in South Asian region and to suggest potential approaches for the prevention and control of this issue of public health significance. An extensive review of literature, covering malnutrition and its determinants, health and economic consequences and pragmatic preventive strategies was performed on computer based bibliographic databases (PubMed, Google Scholar, Scopus, Medline and Sciencedirect.com ) to retrieve abstracts and full texts for India, Pakistan, Bangladesh, Sri Lanka and Nepal. All relevant titles and abstracts were examined and evaluated for malnutrition and its prevalence in South Asia. The results revealed malnutrition to be a major public health problem and a potential cause of high disease burden and mortality in South Asia. Compelling evidence suggests malnutrition to be the leading cause of stunting, wasting and underweight with drastic economic consequences among vulnerable populations. Reduced cognitive performance and low productivity have also been associated with micronutrients malnutrition. Suboptimal breastfeeding, inadequate food supply, micronutrient deficiencies, low household income, poor health care system, increased healthcare costs, illiteracy, unhygienic and substandard living, inappropriate child's care and the caregiver, food insecurity and on top of that vicious cycle of poverty, have been recognized as principal indicators for growing malnutrition prevalence in South Asia. Global organizations, local governments, program managers, NGOs, academia, industry in particular and the society at large need to take up the challenge to completely confiscate malnutrition from the region for economic prosperity and a healthier future.

Prevalence of malnutrition, diarrhea, and acute respiratory infections among under-five children of Sugali tribe of Chittoor district, Andhra Pradesh, India

Introduction:

Over a period, tribal population has migrated to cities in search of livelihood. Data on various health problems of the tribes are sparse. Sugalis constitute the third largest tribe in Andhra Pradesh and have settlements in urban areas.

Objective:

To estimate the prevalence of malnutrition, diarrhea, and acute respiratory infections (ARI) among under-five children of Sugali tribe living in Chittoor district of Andhra Pradesh state in South India.

Materials and Methods:

A community-based cross-sectional study was conducted in four community blocks/mandals in 2012. A total of 500 Sugali households with under-five were identified. Demographic details, episodes of diarrhea, and ARI among under-five children and treatment/care seeking behavior were collected from mothers/care givers by interview. Nutritional status was assessed using new WHO standards.

Results:

Of the total 669 children in these 500 households, 343 (51.3%) were girls and 326 (48.7%) were boys. In the last 1 month, 21.4% (18.4-24.6) reported diarrhea and 51.6% (47.7-55.3) reported ARI. The prevalence of underweight, wasting, and stunting among under-five children was 32.7% (29.1-36.4), 18.3% (15.3-21.4), and 38.3% (34.2-41.9), respectively. Majority (70%) sought treatment for illness in modern system of medicine and only few continued with the practice of herbs and traditional medicine.

Discussion:

Despite living in urban area, the tribal children had high prevalence of malnutrition, diarrhea, and ARI, though lower compared to other tribes in India possibly due to improved access to health care services. Efforts need to be strengthened for social inclusion of tribes into mainstream.

Handwashing, sanitation and family planning practices are the strongest underlying determinants of child stunting in rural indigenous communities of Jharkhand and Odisha, Eastern India: a cross-sectional study

The World Health Organisation has called for global action to reduce child stunting by 40% by 2025. One third of the world's stunted children live in India, and children belonging to rural indigenous communities are the worst affected. We sought to identify the strongest determinants of stunting among indigenous children in rural Jharkhand and Odisha, India, to highlight key areas for intervention.

We analysed data from 1227 children aged 6–23.99 months and their mothers, collected in 2010 from 18 clusters of villages with a high proportion of people from indigenous groups in three districts. We measured height and weight of mothers and children, and captured data on various basic, underlying and immediate determinants of undernutrition. We used Generalised Estimating Equations to identify individual determinants associated with children's height‐for‐age z‐score (HAZ; p < 0.10); we included these in a multivariable model to identify the strongest HAZ determinants using backwards stepwise methods.

In the adjusted model, the strongest protective factors for linear growth included cooking outdoors rather than indoors (HAZ +0.66), birth spacing ≥24 months (HAZ +0.40), and handwashing with a cleansing agent (HAZ +0.32). The strongest risk factors were later birth order (HAZ −0.38) and repeated diarrhoeal infection (HAZ −0.23).

Our results suggest multiple risk factors for linear growth faltering in indigenous communities in Jharkhand and Odisha. Interventions that could improve children's growth include reducing exposure to indoor air pollution, increasing access to family planning, reducing diarrhoeal infections, improving handwashing practices, increasing access to income and strengthening health and sanitation infrastructure.

Gender perceptions predict sex differences in growth patterns of indigenous Guatemalan infants and young children

BACKGROUND

Nearly one-half of Guatemalan children experience growth faltering, more so in indigenous than in nonindigenous children.

OBJECTIVES

On the basis of ethnographic interviews in Totonicapán, Guatemala, which revealed differences in maternal perceptions about food needs in infant girls and boys, we predicted a cumulative sex difference in favor of girls that occurred at ∼6 mo of age and diminished markedly thereafter. We examined whether the predicted differences in age-sex patterns were observed in the village, replicated the examination nationally for indigenous children, and examined whether the pattern in nonindigenous children was different.

DESIGN

Ethnographic interviews (n = 24) in an indigenous village were conducted. Anthropometric measurements of the village children aged 0-35 mo (n = 119) were obtained. National-level growth patterns were analyzed for indigenous (n = 969) and nonindigenous (n = 1374) children aged 0-35 mo with the use of Demographic and Health Survey (DHS) data.

RESULTS

Mothers reported that, compared with female infants, male infants were hungrier, were not as satisfied with breastfeeding alone, and required earlier complementary feeding. An anthropometric analysis confirmed the prediction of healthier growth in indigenous girls than in indigenous boys throughout the first year of life, which resulted in a 2.98-cm height-for-age difference (HAD) between sexes in the village and a 1.61-cm HAD (P < 0.001) in the DHS data between 6 and 17 mo of age in favor of girls. In both data sets, the growth sex differences diminished in the second year of life (P < 0.05). No such pattern was seen in nonindigenous children.

CONCLUSIONS

We propose that the differences in the HAD that first favor girls and then favor boys in the indigenous growth patterns are due to feeding patterns on the basis of gendered cultural perceptions. Circumstances that result in differential sex growth patterns need to be elucidated, in particular the favorable growth in girls in the first year of life.

Prevalence and risk factors of undernutrition among antiretroviral-therapy-naïve subjects aged under 5 years old in Makurdi, Nigeria: a retrospective study

Background

Undernutrition is common in human immunodeficiency virus (HIV) infection and it contributes significantly to its morbidity and mortality. However, as far as we are aware, few studies have described the risk factors of undernutrition among HIV-infected Nigerian children. The study reported here aimed to determine the prevalence and risk factors of undernutrition among HIV-infected, antiretroviral therapy (ART)-naïve children aged under 5 years old in Makurdi, Nigeria.

Methods

A retrospective, cross-sectional study was undertaken at the Federal Medical Centre, Makurdi, between June 2010 and June 2011. Logistic regression modelling was used to determine the risk factors of undernutrition.

Results

Data on 182 HIV-infected children (88 males and 94 females), aged between 6 weeks and 59 months were studied. The prevalence of undernutrition was 12.1%, 33.5%, and 54.4% for underweight, wasting, and stunting, respectively. In multivariate regression analyses, being female (adjusted odds ratio [AOR] 0.292, 95% [confidence interval] CI 0.104–0.820, P=0.019), the child’s caregiver being on ART (AOR 0.190, 95% CI 0.039–0.925, P=0.04), and the absence of tuberculosis in the child (AOR 0.034, 95% CI 0.003–0.357, P=0.005) were independently protective against underweight. Subjects who were exclusively breastfed in the first 6 months of life were protected from stunting (AOR 0.136, 95% CI 0.032–0.585, P=0.007). No factor impacted significantly on wasting in multivariate analyses.

Conclusion

Undernutrition among HIV-infected, ART-naïve children aged under 5 years old may be reduced if programmatic interventions are guided toward early initiation of ART among eligible HIV-infected caregivers and the promotion of HIV/tuberculosis coinfection control efforts. Also, the importance of exclusive breastfeeding in reducing undernutrition cannot be overemphasized.

Malnutrition among under-five children in India and strategies for control

Malnutrition among under-five children is an important concern for the health authorities in India. The aim of the present review was to assess the burden of under-nutrition and over-nutrition, its determinants and strategies required to tackle malnutrition among under-five children in India. Recent data were collected from Google search, Medline, and others. The information retrieved was reviewed and analyzed for discrepancies. Existing evidence shows that the prevalence of under-nutrition among under-five children was high and varied widely (under-weight: 39-75%, stunting: 15.4-74%, wasting: 10.6-42.3%) depending on the assessment methodology adopted. Studies on assessment of over-nutrition status among under-five children were limited. Distribution of various types of risk factors and its influence on nutrition status of children in a given set up should be analyzed for planning the control measures. Strengthening public health interventions for mild malnutrition cases and vulnerable groups, effective implementation and evaluation of the strategies at regional level, research on overweight, obesity and its etiological factors and steps for improving socioeconomic development are the prerequisites for tackling malnutrition among under-five children in India.

Association between farming and chronic energy deficiency in rural South India

Objective

To examine factors associated with chronic energy deficiency (CED) and anaemia in disadvantaged Indian adults who are mostly involved in subsistence farming.

Design

A cross-sectional study in which we collected information on socio-demographic factors, physical activity, anthropometry, blood haemoglobin concentration, and daily household food intake. These data were used to calculate body mass index (BMI), basal metabolic rate (BMR), daily energy expenditure, and energy and nutrient intake. Multivariable backward stepwise logistic regression was used to assess socioeconomic and lifestyle factors associated with CED (defined as BMI<18 kg/m²) and anaemia.

Setting

The study was conducted in 12 villages, in the Rishi Valley, Andhra Pradesh, India.

Subjects

Individuals aged 18 years and above, residing in the 12 villages, were eligible to participate.

Results

Data were available for 1178 individuals (45% male, median age 36 years (inter quartile range (IQR 27–50)). The prevalence of CED (38%) and anaemia (25%) was high. Farming was associated with CED in women (2.20, 95% CI: 1.39–3.49) and men (1.71, 95% CI: (1.06–2.74). Low income was also significantly associated with CED, while not completing high school was positively associated with anaemia. Median iron intake was high: 35.7 mg/day (IQR 26–46) in women and 43.4 mg/day (IQR 34–55) in men.

Conclusions

Farming is an important risk factor associated with CED in this rural Indian population and low dietary iron is not the main cause of anaemia. Better farming practice may help to reduce CED in this population.

Influence of feeding practices and associated factors on the nutritional status of infants in rural areas of Madhya Pradesh state, India

A community based cross-sectional study was undertaken in rural Madhya Pradesh (MP). The nutritional status of infants was assessed using WHO Child Growth Standards. Only 26% of infants received breast-feeding within 1 hour of birth. About 57% of children 6 to 11 months old received complementary feeding (CF). The prevalence of underweight, stunting, and wasting was 41%, 29%, and 33%, respectively. Multivariate analysis showed that the risk of underweight and stunting was 1.4 times higher among children belonging to scheduled castes and scheduled tribes compared with others, 1.4 to 1.6 times among children from households with the lowest wealth index, and 1.5 times among children of illiterate mothers. Hygienic practices, birth weight, home delivery, and CF practices were also significantly (P < .01) associated with undernutrition in multivariate analysis. Undernutrition is an important health problem in MP, and urgent steps are required to formulate policies and strategies to improve infant and young child feeding practices, socioeconomic conditions, and literacy and encouraging institutional delivery and personal hygiene.

Predictors of stunting, wasting and underweight among Tanzanian children born to HIV-infected women

Background

Children born to HIV-infected women are susceptible to undernutrition, but modifiable risk factors and the time course of the development of undernutrition have not been well characterized.

Objective

To identify maternal, socioeconomic, and child characteristics that are associated with stunting, wasting, and underweight among Tanzanian children born to HIV-infected mothers, followed from 6 weeks for 24 months.

Methods

Maternal and socioeconomic characteristics were recorded during pregnancy, data pertaining to the infant’s birth were collected immediately after delivery, morbidity histories and anthropometric measurements were performed monthly. Multivariate Cox proportional hazards methods were used to assess the association between potential predictors and the time to first episode of stunting, wasting, and underweight.

Results

2387 infants (54.0% male) were enrolled and followed for a median duration of 21.2 months. The respective prevalence of prematurity (<37 weeks) and low birthweight (<2500g) was 15.2% and 7.0%; 11.3% of infants were HIV-positive at 6 weeks. Median time to first episode of stunting, wasting, and underweight was 8.7, 7.2, and 7.0 months, respectively. Low maternal education, few household possessions, low infant birthweight, child HIV infection and male sex were all independent predictors of stunting, wasting, and underweight. In addition, preterm infants were more likely to become wasted and underweight, whereas those with a low Apgar score at birth were more likely to become stunted.

Conclusion

Interventions to improve maternal education and nutritional status, reduce mother-to-child transmission of HIV, and increase birth weight may lower the risk of undernutrition among children born to HIV-infected women.

Prevalence of undernutrition, its determinants, and seasonal variation among tribal preschool children of Odisha state, India

A community-based cross-sectional study was undertaken in the tribal areas of Odisha state, India, covering 1951 preschool children to assess their nutritional status in terms of underweight, stunting, and wasting; its correlates; and seasonal variation in nutritional status. χ(2) Test, one-way analysis of variance, and unadjusted and adjusted odds ratios were used for data analysis. The prevalence of underweight, stunting, and wasting was 58%, 65%, and 20%, respectively. The risk of underweight and stunting was, respectively, 1.9 and 2.4 times higher among children of illiterate mothers, whereas underweight and wasting was 1.4 times higher among children who had morbidities during the preceding fortnight. The prevalence of undernutrition was significantly (P < .01) higher during monsoon as compared with winter season. Undernutrition is an important public health problem and is associated with literacy of mother, morbidity, and season. Thus, improving socioeconomic condition, literacy, and sanitation along with insuring food security during monsoon season might improve nutritional status.

Prevalence and determinants of undernutrition and its trends among pre-school tribal children of Maharashtra State, India

A community-based cross-sectional study carried out in tribal areas of Maharashtra covering 1751 pre-school children to assess nutritional status. Nutritional status was assessed using new WHO Growth Standards. Household wealth index was constructed using principle component analysis. The prevalence of underweight, stunting and wasting was 64, 61 and 29%, respectively. There was a significant (p < 0.05) reduction in the prevalence of underweight and stunting over two time periods (1999 and 2008). Logistic regression showed that the risk of underweight was 1.7 times higher among children of illiterate mothers and those suffering from morbidities, while stunting was 1.4 times higher among children belonging to lowest and middle household's wealth indexes. Undernutrition is a public health problem and is associated with literacy of mother, household wealth index and morbidities. Therefore, improving socio-economic condition along with literacy of mothers and preventing infections through personal hygiene might help in improving the nutritional status of children.
