Individual, household, and community level risk factors of stunting in children younger than 5 years: Findings from a national surveillance system in Nepal

Measuring Community Urbanicity and Its Influence on Household Food Security Across Nepal's Agroecological Zones

Background

Urbanization influences food systems and food security, but research on these associations in low- and middle-income countries remain limited, partly because of the binary and unstandardized "urban compared with rural" classifications.

Objectives

To develop a community urbanicity scale, to assess its associations with household food security, and to explore whether agricultural occupation modifies this relationship across the 3 agroecological zones (mountain, hill, Tarai) of Nepal.

Methods

Data came from a nationally and agroecologically representative, multistaged 2013 agri-food system survey of 4285 households with children <5 y in 63 communities (wards) in Nepal. A novel community-level urbanicity scale was constructed using factor analysis that included 8 domains. Multilevel mixed effects logistic regression was used to assess associations between urbanicity and household food security (measured using the validated Household Food Insecurity Access Scale), and to investigate modifying effects of agricultural occupation.

Results

Urbanicity scores ranged between 13 and 69, of a possible 80 points. Most agricultural households in the mountains (67%) and hills (54%) were categorized food insecure. Increases in urbanicity were negatively associated with food insecurity, controlling for other factors (odds ratio [OR] per 10-unit urbanicity difference OR: 0.82; confidence interval [CI]: 0.71, 0.94; P ≤ 0.05). Agricultural occupation may have positively influenced this association though was not a statistically significant effect measure modifier (P = 0.07).

Conclusions

The novel scale shows more nuance within Nepal's agroecological zones, which had similar urbanicity-to-food security relationships as well as overlapping urbanicity score distributions. Research and policy efforts should consider using scales providing more precise urbanicity measurement, and thus informative assessments on its role in predicting food insecurity, especially in agriculturally reliant populations.

Analysis of traditional feeding practices and stunting among children aged 6 to 59 months in Karanganyar District, Central Java Province, Indonesia

BACKGROUND

Traditional feeding practices are widespread in Indonesia. Therefore, using traditional feeding practices commonly used among mothers, this study examined the association between these practices and stunting along with other relevant factors (i.e., sociodemographic factors, feeding practices, vaccination status, and place of residence).

METHODS

This cross-sectional study was conducted in Karanganyar District, Central Java Province. Data from a total of 706 children aged 6 to 59 months (352 children with stunting and 354 children without stunting) were obtained from the medical records of 10 primary health care units (PHCUs) in 9 subdistricts. Descriptive analysis and binary logistic regression (BLR) were performed to explore the association between the dependent (stunting) and independent variables.

RESULTS

The BLR results from children 6 to 59 months indicated that children of mothers with food restrictions during pregnancy (AOR = 5.87, 95% CI: 3.03, 11.38), children with prelacteal feeding (AOR = 4.27, 95% CI: 2.16, 8.41) and children with food restrictions (AOR = 7.74, 95% CI: 1.22, 49.16) were more likely to experience stunting. Those from children 6 to 23 months revealed that food restrictions during pregnancy (AOR = 17.55, 95% CI: 2.86, 107.80) and prelacteal feeding (AOR = 10.58, 95% CI: 2.06, 54.41) were related to stunting. The reasons for traditional feeding practices were related to cultural beliefs. For example, mothers believed that red meat could cause high blood pressure; thus, the consumption of red meat could trigger miscarriage or bleeding during delivery. In addition, this study showed that low sociodemographic status, inappropriate feeding practices, incomplete vaccination, and residence in rural areas were related to stunting.

CONCLUSIONS

The findings reflect the importance of education for mothers to correct misconceptions of traditional feeding practices. The government should strengthen counseling services in PHCUs to improve mothers' knowledge of and attitudes toward appropriate feeding practices. Additionally, public relations practices through the mass media should continue for family members, especially senior members, as they influence mothers' autonomy in decision-making regarding feeding practices in Indonesia.

A systematic review of the relationship between household food insecurity and childhood undernutrition

BACKGROUND

This systematic review aims to investigate the association between household food insecurity (HFIS) and undernutrition in children under 5 years old, thereby informing policymakers on the vital factors needed to be considered in tailoring an effective strategy to tackle childhood undernutrition and ultimately HFIS.

METHODS

We performed a systematic review that examined household food insecurity among the undernourished under-five children. PubMed, Cochrane, EBSCO Host, Web of Science and Cumulative Index to Nursing and Allied Health Literature were searched from 1 January 2012 to 1 April 2022, for relevant articles. Outcome measures were stunting, underweight or wasting. Of the 2779 abstracts screened, 36 studies that fulfilled the inclusion and exclusion criteria were included. A range of tools had been used to measure HFIS, the most common being Household Food Insecurity Access Scale. HFIS has been found to be significantly associated with undernutrition, particularly stunting and underweight. This is observed proportionately across all national income levels.

CONCLUSIONS

Sustainable and inclusive economic growth, which aims to reduce income, education and gender inequality, should be a key policy goal in the minimizing food insecurity and childhood undernutrition. Multisectoral interventions are needed to address these issues.

Analyzing determinants from both compositional and contextual level impeding desired linear growth of children in Indian context

Childhood stunting is recognized as significant public health concern in India. It is a form of malnutrition with impaired linear growth and creates a range of adversaries among children, including under-5 mortality, morbidity, and physical and cognitive growth. The purpose of the present study was to recognize the various leading determinants causing childhood stunting from both individual and contextual level in Indian context. Data were obtained from the India's Demography and Health Survey (DHS) conducted in 2019-2021. A total of 1, 46,521 children aged 0-59 months were included in this present study. The study applied a multilevel mixed-effect logistic regression model in which individual factors nested within community based contextual-level factors estimating the likelihood of childhood stunting phenomena among Indian children. The variance explained in full model accounted for about 35.8% of the odds of stunting across the communities. The present study elucidates that the recognized factors from individual level characteristics have really increased the odds of childhood stunting: gender of child, multiple births, low birth weight, low BMI among mothers, less educational attainment by mothers, maternal anemic status, breast feeding duration longer than usual, < 4 antenatal care (ANC) visits during gestation period. Similarly, contextual-level factors like rural places of residence, western Indian children, and communities with high poverty rates, lower literacy rates, improper sanitation, and unsafe drinking water were also found to have a significant positive association with childhood stunting. The study finally concludes that cross level interaction between individual and contextual-level factors are identified as significant determinants of linear growth retardation among child in India. In order to reduce this type of malnutrition among the child one should more concentrate on both individual and contextual-level factors as a notable reasons.

Child-sensitive water, sanitation, and hygiene composite score and its association with child nutritional outcomes in St. Martin's Island, Bangladesh

Objectives

This study aimed to outline water, sanitation, and hygiene (WASH) practices for children under 5 years of age among the households of St. Martin's Island as well as examine the role of water, sanitation, and hygiene on child nutritional outcomes.

Methods

A total of 256 children under 5 years of age were anthropometrically measured, and multiple linear regression was performed to understand the relationship between combined water, sanitation, and hygiene score and child nutritional outcomes: height-for-age, weight-for-age, weight-for-height z-scores.

Results

The majority of the sampled households had improved drinking water facilities. Over one-third of the participants (36.5%) did not have access to better sanitation, and 12.4% reported defecating in open places. Just over one-third of those surveyed reported washing their hands with soap or detergents after defecation, with more than 22% of people not having access to a handwashing station on their premises. Stunting, wasting, and underweight were found to be prevalent in 34.4%, 17.6%, and 18.9% of the sampled children, respectively. Height-for-age (0.08 SDs) and weight-for-age (0.014 SDs) were greater on average in children from households with improved water, sanitation, and hygiene conditions, but weight-for-height did not significantly differ from those from WASH-unimproved households.

Conclusion

Certain aspects of WASH, particularly, sanitation facilities and hygiene practices were not up to the mark in St. Martin's Island, and consistent with findings from other studies, our study findings underlined the potential benefits of improved water, sanitation, and hygiene practices in addressing child undernutrition.

Nutritional health status: association of stunted and wasted children and their mothers

Background

Across the globe, 149 and 49 million children are stunted and wasted, respectively. Prevalence of stunting and wasting is 40.2 and 17.7% in children of Pakistan. Stunting and wasting are accompanied with genetics, dietary factor, lack of information, bottle feeding, illiterate parents, less birth interval, infection such as diarrhoea, low birth weight, mother suffering from malnutrition during pregnancy, breastfeeding, pharmaceutical, and hormonal, psychosocial, and low social-economic status.

Methods

Stunted and wasted children and their mothers were called on and detail discussions related to research plan were carried out. Informed consent was assured from mothers, for participation in the study. The demographics, anthropometrics, vital signs observations, body composition, clinical signs and symptoms, dietary intake and associated biomarkers (CBC, level of urea nitrogen in blood, serum albumin globulin and serum creatinine.) were tools for nutritional health status assessment. SPSS software was implied on data.

Results

The study found that 27.2% mothers were belonged to stunted children, 17.3% belonged to wasted children, and 50.9% belonged to those children who were suffering from both stunting and wasting condition.57.9% mothers who were illiterate belong to stunted and wasted children. CBC and Hb test was prominent, stunted and wasted children had Hb 9.88 mg/dL, whereas, their mothers had 10.8 mg/dL as average Hb. The average height and weight of stunted and wasted children was 68.6 cm and 7.11 kg respectively. Dietary patterns and diet quality of both mothers and children were poor, due to lack of affordability; they were not able to eat healthy food.

Conclusion

Stunting and wasting ultimately resulted in poor growth and development of children. Most of children were anemic, they height and weight less than WHO growth standards. They had less knowledge and poor intake of food diet pattern so children growth was poor.

Socioeconomic and demographic correlates of child nutritional status in Nepal: an investigation of heterogeneous effects using quantile regression

Background

Child undernutrition continues to be a major public health problem in many countries, including Nepal. The repercussions of undernutrition are not only limited to the affected children and families but also transcend to the national and global economy. Earlier studies from Nepal have predominantly used either ordinary least squares (OLS) regression or binary regression to analyse the socioeconomic and demographic correlates of the nutritional outcome. In this study, quantile regression was used to understand a complete and more precise estimate of the effects of the covariates on the child nutritional status.

Methods

This study was based on the most recent nationally representative Nepal Multiple Indicator Cluster Survey (MICS) 2019. Height-for-age z scores (HAZ) were used as an indicator for assessing the nutritional status of under-five children. Quantile regression was used to examine the heterogeneous association of covariates with conditional HAZ distribution across the different quantiles (0.10, 0.30, 0.50, 0.85). As a comparison, the effects of covariates at conditional mean of HAZ using OLS regression was also analysed. The graphs were plotted to visualize the changes in the coefficients for each regressor across the entire conditional HAZ distribution.

Results

Age of children, sex of children, province and wealth had a consistent and statistically significant association with HAZ in both OLS and quantile regression. Improved toilet facility was positively correlated with HAZ at the lower tails (tenth and thirtieth percentiles). Ethnicity (Janajati and Newer) was positively correlated with HAZ at the lower tail (thirtieth percentile) and mean (OLS regression). Maternal education was a significant predictor of improved height-for-age across conditional quantiles, except at the tenth percentile. Maternal age, number of under-five children in household, number of household members, and improved source of drinking water showed heterogeneous effects across different quantiles of conditional HAZ distribution.

Conclusion

Use of quantile regression approach showed that the effect of different factors differed across the conditional distribution of HAZ. Policymakers should consider the heterogeneous effect of different factors on HAZ so that the targeted intervention could be implemented to maximize the nutritional benefits to children.

Reducing childhood stunting in India: Insights from four subnational success cases

Global success case analyses have identified factors supporting reductions in stunting across countries; less is known about successes at the subnational levels. We studied four states in India, assessing contributors to reductions in stunting between 2006 and 2016. Using public datasets, literature review, policy analyses and stakeholder interviews, we interpreted changes in the context of policies, programs and enabling environment. Primary contributors to stunting reduction were improvements in coverage of health and nutrition interventions (ranged between 11 to 23% among different states), household conditions (22–47%), and maternal factors (15–30%). Political and bureaucratic leadership engaged civil society and development partners facilitated change. Policy and program actions to address the multidimensional determinants of stunting reduction occur in sectors addressing poverty, food security, education, health services and nutrition programs. Therefore, for stunting reduction, focus should be on implementing multisectoral actions with equity, quality, and intensity with assured convergence on the same geographies and households.

Household Water Access, Dietary Diversity and Nutritional Status among Preschoolers in Poor, Rural Areas of Central and Western China

Poor child feeding and childhood malnutrition are major public health problems in rural central and western China, with little evidence about their environmental determinants. This study aimed to investigate whether household water access is associated with dietary diversity and nutritional outcomes. We analyzed the cross-sectional data of 3727 children aged 6 to 59 months in rural central and western China, applying multivariate linear and logistic models to estimate the effect of water access on children’s anthropometric indices, hemoglobin, and dietary diversity. We found that unimproved water access was linked to a lower likelihood of achieving dietary diversity (OR = 0.65, 95% CI 0.44 to 0.98, p = 0.039); lower height-for-age z-score (β = −0.34, 95% CI −0.49 to −0.19, p < 0.001) and hemoglobin concentration (β = −2.78, 95% CI −5.16 to −0.41, p = 0.022); higher odds of stunting (OR = 1.50, 95% CI 1.01 to 2.25, p = 0.047) and anemia (OR = 1.34, 95% CI 1.02 to 1.77, p = 0.037). The associations between water access and nutritional outcomes were not explained by dietary diversity and were stronger in children who did not receive iron supplementation. These findings provide evidence for designing water-based nutritional interventions in China.

Food Insecurity, Nutritional Inequality, and Maternal–Child Health: A Role for Biocultural Scholarship in Filling Knowledge Gaps

Food insecurity, a significant contributor to nutritional inequality, disproportionately affects women and children in low- and middle-income countries. The magnitude of the problem has inspired research on its impacts on health, especially on nutritional status and, more recently, mental well-being. Current research is dominated by surveillance-type studies that emphasize access, one of food security's four dimensions. Findings are inconclusive regarding the association between food insecurity and women and children's nutritional status, but some evidence indicates that it is a key contributor to mental distress in women. To understand these inconsistent findings, we emphasize the need for research on the strategies that people use to cope with inadequate access to food. We contend that biocultural approaches that recognize the importance of local contexts and the role of broader political-economic factors in shaping them are well suited for addressing current knowledge gaps.

Effective nutrition governance is correlated with better nutrition outcomes in Nepal

BACKGROUND

The public health burden of undernutrition remains heavy and widespread, especially in low-income countries like Nepal. While predictors of undernutrition are well documented, few studies have examined the effects of political will and quality of policy or program implementation on child growth.

METHODS

Data were collected from two nationwide studies in Nepal to determine the relationship between a metric of nutrition 'governance' (the Nutrition Governance Index), derived from interviews with 520 government and non-government officials responsible for policy implementation and anthropometry measured for 6815 children in 5556 households. We employed Generalized Estimating Equation (GEE) and multilevel regression models.

RESULTS

A higher NGI (more effective nutrition governance) is positively associated with height-for-age as well as weight-for-height in children over 2 years of age compared to younger children (HAZ; β = 0.02, p < 0.004, WHZ; β = 0.01, p < 0.37). Results from the hierarchical model show that a one-point increase in the NGI is significantly associated with a 12% increase in HAZ and a 4% increase in WHZ in older children (> 24 months old). Mothers' education, child's age, BMI and no fever in the past 30 days were also protective of stunting and wasting. Seven percent and 17% of the overall variance in HAZ and WHZ, respectively, are accounted for by variations across the 21 district locations in which sampled households were located. Mean HAZ differs considerably across districts (intercept = 0.116, p < 0.001).

CONCLUSIONS

These results highlight the importance of effective management of policy-based programming and resource use to bring about nutrition gains on the ground. The NGI explained a non-negligible amount of variation in HAZ and WHZ, which underscores the fundamental role that good governance plays in promoting child nutrition and growth, and the value of seeking to measure it to assist governments in moving policies from paper to practice.

Are children in female-headed households at a disadvantage? An analysis of immunization coverage and stunting prevalence: in 95 low- and middle-income countries

Studies of inequalities in child health have given limited attention to household structure and headship. The few existing reports on child outcomes in male and female-headed households have produced inconsistent results. The aim of our analyses was to provide a global view of the influence of sex of the household head on child health in cross-sectional surveys from up to 95 LMICs. Studied outcomes were full immunization coverage in children aged 12-23 months and stunting prevalence in under-five children. We analyzed the most recent nationally-representative surveys for each country (since 2010) with available data. After initial exploratory analyses, we focused on three types of households: a) male-headed household (MHH) comprised 73.1% of all households in the pooled analyses; b) female Headed Household (FHH) with at least one adult male represented 9.8% of households; and c) FHH without an adult male accounted for 15.0% of households. Our analyses also included the following covariates: wealth index, education of the child's mother and urban/rural residence. Meta-analytic approaches were used to calculate pooled effects across the countries with MHH as the reference category. Regarding full immunization, the pooled prevalence ratio for FHH (any male) was 0.99 (0.97; 1.01) and that for FHH (no male) was 0.99 (0.97; 1.02). For stunting prevalence, the pooled prevalence ratio for FHH (any male) was 1.00 (0.98; 1.02) and for FHH (no male) was 1.00 (0.98; 1.02). Adjustment for covariates did not lead to any noteworthy change in the results. No particular patterns were found among different world regions. A few countries presented significant inequalities with different directions of association, indicating the diversity of FHH and how complex the meaning and measurement of household headship may be. Further research is warranted to understand context, examine mediating factors, and exploring alternative definitions of household headship in countries with some association.

Urban-Rural Disparities in the Magnitude and Determinants of Stunting among Children under Five in Tanzania: Based on Tanzania Demographic and Health Surveys 1991-2016

Our study aims to examine the disparity of under-5 child stunting prevalence between urban and rural areas of Tanzania in the past three decades, and to explore factors affecting the rural–urban disparity. Secondary analyses of Tanzania Demographic and Health Surveys (TDHS) data drawn from 1991–1992, 1996, 1999, 2004–2005, 2009–2010, and 2015–2016 surveys were conducted. Under-5 child stunting prevalence was calculated separately for rural and urban children and its decline trends were examined by chi-square tests. Descriptive analyses were used to present the individual-level, household-level, and societal-level characteristics of children, while multivariable logistic regression analyses were performed to examine determinants of stunting in rural and urban areas, respectively. Additive interaction effects were estimated between residence and other covariates. The results showed that total stunting prevalence was declining in Tanzania, but urban–rural disparity has widened since the decline was slower in the rural area. No interaction effect existed between residence and other determinants, and the urban–rural disparity was mainly caused by the discrepancy of the individual-level and household-level factors between rural and urban households. As various types of determinants exist, multisector nutritional intervention strategies are required to address the child stunting problem. Meanwhile, the intervention should focus on targeting vulnerable children, rather than implementing different policies in rural and urban areas.

Changes in socio-economic inequality in nutritional status among children in EAG states, India

OBJECTIVE

The primary purpose of this study is to examine changes in socio-economic inequality in nutritional status (stunting and underweight) among children in Empowered Action Group (EAG) states.

DESIGN

The study is based on the most recent two wave's cross-sectional data from the National Family Health Survey (NFHS) conducted in 2005-2006 (NFHS-3) and 2015-2016 (NFHS-4). The study used height-for-age (stunting) and weight-for-age (underweight) of children as anthropometric indicators.

SETTING

EAG states including Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, Uttarakhand and Uttar Pradesh in India.

PARTICIPANTS

The study includes a total of 11 858 (NFHS-3) and 92 630 (NFHS-4) children under 5 years of age.

RESULT

The socio-economic inequality in stunting remained unchanged in all EAG states. At the same time, the inequality in underweight decreased during 2005-2016. On decomposing, the factors contributing to socio-economic inequality revealed that household wealth index, mother's education and mother's nutritional status were the largest contributors to stunting (47 %, 24 % and 8 %) and underweight (51 %, 21 % and 16 %), respectively, in 2015-2016.

CONCLUSION

The study concluded the socio-economic inequality in underweight among children under 5 years of age increased over the years in EAG states in India. Altogether, household wealth index, mother's education and mother's nutritional status contributed to nearly 80 % to inequality in stunting and 90 % to inequality in underweight in 2015-2016. Hence, efforts should be made to minimise the socio-economic inequality in the nutritional status of children, particularly in EAG states in India.

Drivers of stunting reduction in Nepal: a country case study

BACKGROUND

Chronic child malnutrition represents a serious global health concern. Over the last several decades, Nepal has seen a significant decline in linear growth stunting - a physical manifestation of chronic malnutrition - despite only modest economic growth and significant political instability.

OBJECTIVE

This study aimed to conduct an in-depth assessment of the determinants of stunting reduction in Nepal from 1996 to 2016, with specific attention paid to national-, community-, household-, and individual-level factors, as well as relevant nutrition-specific and -sensitive initiatives rolled out within the country.

METHODS

Using a mixed-methods approach, 4 types of inquiry were employed: 1) a systematic review of published peer-reviewed and gray literature; 2) retrospective quantitative data analyses using Demographic and Health Surveys from 1996 to 2016; 3) a review of key nutrition-specific and -sensitive policies and programs; and 4) retrospective qualitative data collection and analyses.

RESULTS

Mean height-for-age z-scores (HAZ) improved by 0.94 SDs from 1996 to 2016. Subnational variation and socioeconomic inequalities in stunting outcomes persisted, with the latter widening over time. Decomposition analysis for children aged under 5 y explained 90.9% of the predicted change in HAZ, with key factors including parental education (24.7%), maternal nutrition (19.3%), reduced open defecation (12.3%), maternal and newborn health care (11.5%), and economic improvement (9.0%). Key initiatives focused on decentralizing the health system and mobilizing community health workers to increase accessibility; long-standing nationwide provision of basic health interventions; targeted efforts to improve maternal and child health; and the prioritization of nutrition-sensitive initiatives by both government and donors. National and community stakeholders and mothers at village level highlighted a mixture of poverty reduction, access to health services, improved education, and increased access to water, sanitation, and hygiene as drivers of stunting reduction.

CONCLUSIONS

Improvements in both nutrition-specific and nutrition-sensitive sectors have been critical to Nepal's stunting decline, particularly in the areas of poverty reduction, health, education, and sanitation.

Why under five children are stunted in Pakistan? A multilevel analysis of Punjab Multiple indicator Cluster Survey (MICS-2014)

BACKGROUND

Pakistan is facing a serious problem of child under-nutrition as about 38% of children in Pakistan are stunted. Punjab, the largest province by population and contributes high gross domestic product (GDP) share in economy has reported 27% moderately and 10% severely stunted children of less than 5 years. Thus, this study aims at examining the determinants of stunting (moderate and severe) at different level of hierarchy empirically in Punjab province of Pakistan.

METHODOLOGY

Data for this study is coming from Punjab Multiple Indicators Cluster Survey (MICS-2014), used two-stage, stratified cluster sampling approach. Sub-national level data covering urban and rural areas were used for this study consists of 25,067 children less than 5 year's ages, from nine administrative divisions and 36 districts of Punjab province of Pakistan. Descriptive statistics and multilevel hierarchical models were estimated. Multilevel data analyses have an advantage because it provides robust standard error estimates and helps in finding variation in the data at various levels.

RESULTS

Punjab has a stunting prevalence of about 27% moderately and 10% severely stunted children of less than 5 years. The results depict that increasing the age of the child, increasing birth order, illiterate mothers and fathers, lack of sanitation facilities and being poor are associated significantly with the likelihood of moderate and severe stunting. Surprisingly, there is a gender bias in stunting in Punjab, Pakistan and being a girl child is more likely associated with moderate and severe stunting, which shows the patriarchal nature of the society and a substantial prevalence of gender bias in household resource allocations.

CONCLUSION

This outcome of our analysis points towards targeting not only households (focus on girls) but also their families and communities.

Preschool Child Nutritional Status in Nepal in 2016: A National Profile and 40-Year Comparative Trend

BACKGROUND

Preschool child anthropometric status has been assessed nationally in Nepal since 1975, with semi-decadal surveys since 1996, plus several recent, short-interval surveys to track progress toward achieving a World Health Assembly (WHA) goal to reduce stunting to 24% by 2025.

OBJECTIVE

We report prevalence of preschool child stunting and wasting from a national survey in 2016 and place findings into the context of national trends and alignment for Nepal to attain its WHA 2025 goal.

METHODS

A representative, midyear Policy and Science for Health, Agriculture and Nutrition (PoSHAN) survey was conducted in 2016 on 5479 children <60 months in 4051 households in 21 village development committees. Child weight and height were measured, and sociodemographic factors were assessed. Data from previous surveys (Nepal Demographic Health Surveys, PoSHAN) were also acquired, and rates of stunting (<-2 height-for-age z score) and wasting (<-2 weight-for-height z score) were compared to current World Health Organization standards. Trends were expressed as average annual rates of reduction (AARR).

RESULTS

Nationally, in 2016, 34.1% of preschoolers were stunted and 13.7% wasted. Stunting was highest in the Mountains (40.6%) and wasting highest in the Tarai (18.9%). Trend analysis revealed a steady decline (3.8% AARR) in stunting from 2001 to 2013, with virtually no decline from 2013 to 2016. Wasting has been continually high and variable, at ≥8%, since 1975.

CONCLUSIONS

Following a steady decline in prevalence, preschool child stunting has plateaued at ∼35% in Nepal, while wasting has changed little over time, offering the opportunity to inform, reassess, and adjust, as needed, efforts to reach WHA 2025 goals.

Water, sanitation and hygiene practices associated with improved height-for-age, weight-for-height and weight-for-age z-scores among under-five children in Nepal

BACKGROUND

Evidence of the influence of water, sanitation and hygiene (WASH) behaviors on childhood nutritional status is inconsistent. Few studies have examined their interactive effects. This study aimed to examine associations and interactions between WASH variables and preschool child undernutrition.

METHODS

Data from a nationally representative sample of 2352 children assessed during the 2016 Nepal Demographic and Health Survey were analyzed by multi-variable linear regression to understand the association between height-for-age (HAZ), weight-for-height (WHZ) and weight-for-age (WAZ) z-scores and WASH variables. Interactions between WASH variables, sex and area of residence on childhood nutritional status were also examined.

RESULTS

The mean z-score [standard deviation] for children's WAZ, HAZ and WHZ scores were - 1.33 [1.1], - 1.52 [1.3] and - 0.65 [1.1], respectively. A unit increase in cluster sanitation coverage was associated with an increase of 0.30 (95%CI: 0.12 to 0.48) for WAZ and 0.28 (95%CI: 0.001 to 0.56) for HAZ scores. Household water purification practice was associated with an increase of 0.24 (95%CI: 0.07 to 0.41) in WHZ score. Handwashing practice with water and soap was associated with an increase of 0.15 (95%CI: 0.04 to 0.25) in WAZ and 0.13 (95%CI: 0.01 to 0.24) in WHZ scores. The effect of water purification practice was higher for rural areas compared to urban settings for HAZ scores (p-value for interaction = 0.02).

CONCLUSIONS

Consistent with findings from other countries in the South Asian region, findings of this study highlight the potential importance of good WASH practices, and therefore the potential of WASH interventions, to contribute to improved nutritional status in rural Nepal.

To see, hear, and live: 25 years of the vitamin A programme in Nepal

Nepal has a rich history of vitamin A research and a national, biannual preschool vitamin A supplementation (VAS) programme that has sustained high coverage for 25 years despite many challenges, including conflict. Key elements of programme success have included (a) evidence of a 26–30% reduction in child mortality from two, in‐country randomized trials; (b) strong political and donor support; (c) positioning local female community health volunteers as key operatives; (d) nationwide community mobilization and demand creation for the programme; and (e) gradual expansion of the programme over a period of several years, conducting and integrating delivery research, and monitoring to allow new approaches to be tested and adapted to available resources. The VAS network has served as a platform for delivering other services, including anthelmintic treatment and screening for acute malnutrition. We estimate that VAS has saved over 45,000 young lives over the past 15 years of attained national coverage. Consumption of vitamin A‐ and carotenoid‐rich foods by children and women nationally remains low, indicating that supplementation is still needed. Current challenges and opportunities to improving vitamin A status include lower VAS coverage among younger children (infants 6–11 months of age), finding ways to increase availability and access to dietary vitamin A sources, and ensuring local programme investments given the recent decentralization of the government.

Small-Scale Livestock Production in Nepal Is Directly Associated with Children's Increased Intakes of Eggs and Dairy, But Not Meat

Animal source foods (ASF) provide nutrients essential to child growth and development yet remain infrequently consumed in rural Nepal. Agriculture and nutrition programs aim to increase ASF intake among children through small-scale animal husbandry projects. The relationship between livestock ownership and children's consumption of ASF, however, is not well established. This study examined associations between livestock ownership and the frequency with which Nepali children consume eggs, dairy, and meat. We analyzed longitudinal 7-day food frequency data from sentinel surveillance sites of the Policy and Science of Health, Agriculture and Nutrition (PoSHAN) study. Data consisted of surveys from 485 Nepali farming households conducted twice per year for two years (a total of 1449 surveys). We used negative binomial regression analysis to examine the association between the number of cattle, poultry, and meat animals (small livestock) owned and children's weekly dairy, egg, and meat intakes, respectively, adjusting for household expenditure on each food type, mother's education level, caste/ethnicity, agroecological region, season, and child age and sex. We calculated predicted marginal values based on model estimates. Children consumed dairy 1.4 (95% CI 1.1-2.0), 2.3 (1.7-3.0) and 3.0 (2.1-4.2) more times per week in households owning 1, 2-4 and >4 cattle, respectively, compared to children in households without cattle. Children consumed eggs 2.8 (2.1-3.7) more times per week in households owning 1 or 2 chickens compared to children in households without chickens. Child intake of meat was higher only in households owning more than seven meat animals. Children's intakes of dairy, eggs, and meat rose with household expenditure on these foods. Small-scale animal production may be an effective strategy for increasing children's consumption of eggs and dairy, but not meat. Increasing household ability to access ASF via purchasing appears to be an important approach for raising children's intakes of all three food types.

Prevalence of damaged and missing teeth among women in the southern plains of Nepal: Findings of a simplified assessment tool

Objective

To assess the prevalence of missing and damaged teeth among women in the rural southern plains of Nepal using an interviewer-administered tooth assessment module.

Setting

21wards in seven Village Development Committees across the Tarai of Nepal in 2015.

Participants

Resident, married women of children less than 5 years of age or those married in the 2 years prior to the survey, 14 to 49 years of age participating in a mid-year nutrition and health survey in the Tarai region of Nepal.

Outcome measures

Prevalence of missing and damaged teeth, history of dental problems, oral hygiene practices, access to dental treatment and risk factors for missing and damaged teeth.

Results

Of 3007 assessed women, aged 14 to 49 years of age, 22.8% (95% CI: 21.4–24.4) reported ≥ 1 missing or damaged teeth; 81.5% (95% CI 80.1–82.9) reported regularly practicing oral hygiene, typically with standard local dentifrices. Pain or discomfort in the oral cavity in the previous 6 months affected 17.6% of women. Among these, 43.8% had sought treatment from a dental facility, pharmacy or village doctor. Home remedies were commonly applied to relieve pain.

Conclusion

Broken and missing teeth are common, affecting nearly one-quarter of adult women of reproductive age in rural Southern Nepal, as assessed by an interviewer-administered questionnaire.

Individual-, Household-, and Community-Level Determinants of Childhood Undernutrition in Bangladesh

Introduction:

Childhood undernutrition is a crucial public health problem globally. The objective of this study is to measure the prevalence of childhood undernutrition and assess the distinct role of various factors on childhood undernutrition in Bangladesh.

Methods:

This study utilized the latest cross-sectional data from Bangladesh Demographic and Health Survey 2014. A total of 7256 data on children younger than 5 years old were analyzed. The undernutrition status of children was assessed by stunting (height-for-age), wasting (weight-for-height), and underweight (weight-for-age), while bivariate and multivariate analyses were performed to identify various individual-, household-, and community-level factors of childhood undernutrition.

Results:

The prevalence of stunting, wasting, and underweight were 36.5%, 14.6%, and 32.5%, respectively. Along with various individual- and household-level factors (eg, age, recent diarrheal disease, fever, number of under-5 children in the household, mother’s education and nutritional status, and wealth status), community index, particularly regional and geographic variation of community, had significant role for childhood undernutrition in Bangladesh.

Conclusion:

Childhood undernutrition is an overwhelming public health issue in Bangladesh. In order to improve the nutritional status of under-5 children, interventions should take into account the various predictors discussed in this study. Indeed, a joint effort by the government, nongovernmental organizations, and the community is necessary to improve the childhood nutritional status in Bangladesh.

Predictors of stunting among children 6-59 months of age in Sodo Zuria District, South Ethiopia: a community based cross-sectional study

Background

Despite the decline in the rate of stunting in Ethiopia, the prevalence is still high and needs immense efforts to achieve the target set to reduce the prevalence. It varies between localities due to individual level factors and dominant livelihood practice in the community.

Thus, the aim of this study was to determine the prevalence of stunting and identify factors associated with it in Sodo Zuria district in South Ethiopia.

Methods

A community based cross sectional study was conducted among 342 children aged 6–59 months paired with mothers/caretakers. Households were selected using systematic sampling. Structured questionnaire was used and mothers/caregivers were interviewed face to face. Standardized anthropometric measurements were used to measure length, and weight and height of a child. Data were entered into Epi Info software version 3.5.1 and exported to SPSS version 20 for analysis. Height for age Z score data were analyzed using WHO Anthro software. Multivariate logistic regression analysis was conducted to identify predictor variables. Statistical significance was considered at p < 0.05.

Results

The prevalence of stunting in this study was 24.9% with 7.9% being severely stunted. Being female (AOR = 2.8; 95% CI: 1.5, 5.3), children aged 12–23 months (AOR = 7.1; 95% CI: 2.3, 21.9), mother’s who do not use family planning (AOR = 2.5; 95% CI: 1.1,5.7), children with diarrheal morbidity (AOR = 2.5; 95% CI: 1.2,5.3), income of 750–1500 ETB and > 1500, and children who received pre-lacteal feeding (AOR = 3.8; 95% CI: 1.2–12.2) became predictors for stunting.

Conclusion

Significant proportion of stunting was found where one third of them were severely stunted. Being female, children aged 12–23 months, using family planning, children with diarrheal morbidity, income and pre-lacteal feeding became predictors for stunting. So Gender-based policies should be enacted in child feeding practice, interventions should focus on the utilization of family planning and appropriate child caring and feeding practices. Water, sanitation and hygiene interventions need to be strengthened.

Food insecurity and the risk of undernutrition complications among children and adolescents: A systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis was performed to examine the association between household food insecurity and the risk of being underweight, stunting, and wasting in children and adolescents.

METHODS

Pertinent studies were identified by searching PubMed, Web of Science, and Scopus databases up to June 2018. A total of 21 studies met the inclusion criteria to be included in the pooled analysis. The risk ratio of 55 173 individuals from 12 different countries were pooled in these studies for our meta-analysis.

RESULTS

It was found that food insecurity increased the risk of stunting (odds ratio [OR] = 1.17; 95% confidence interval [CI]: 1.09-1.25) and underweight (OR = 1.17; 95% CI: 1.01-1.36) but not of wasting (OR = 1.04; 95% CI: 0.96-1.12). Subgroup analysis by age indicated that food insecurity increased the risk of stunting (OR = 1.20; 95% CI: 1.02-1.39) and underweight (OR = 1.34; 95% CI: 1.02-1.77) in children older than 5 y. This association was significant just for stunting risk (OR = 1.14; 95% CI: 1.05-1.23) in children younger than 5 y. Furthermore, among children and adolescents, risk of stunting or being underweight increased by the intensification of the level of food insecurity in food-insecure households. Furthermore, subgroup analysis by country development levels showed that children and adolescents living in developing countries had higher risk of stunting (OR = 1.16; 95% CI: 1.05-1.27).

CONCLUSIONS

Household food insecurity appears to be associated with higher risk of stunting and being underweight among children and adolescents. In addition, the intensification of the level of food insecurity and the increased age of children may increase the risk of stunting or being underweight in food-insecure households. Also, the level of economic development is an important factor in the effects of food insecurity on risk of stunting.

Nutritional status and risk factors for stunting in preschool children in Bhutan

Childhood malnutrition remains endemic in South Asia, although the burden varies by country. We examined the anthropometric status and risk factors for malnutrition among children aged 0–59 months through the 2015 National Nutrition Survey in Bhutan. We assessed in 1,506 children nutritional status (by z‐scores of height‐for‐age [HAZ], weight‐for‐height [WHZ], and weight‐for‐age [WAZ]), estimating prevalence, adjusted for survey design, of stunting, wasting, underweight, and overweight (<−2 for HAZ, WHZ, and WAZ and >2 for WHZ). Children were also assessed for pedal oedema. We conducted multivariable linear/logistic regression analysis to identify child, maternal, and household risk factors for childhood undernutrition and overweight, excluding children with oedema (1.7%). Mean (SE) HAZ, WHZ, and WAZ were −0.82 (0.13), 0.10 (0.04), and −0.42 (0.05), respectively. Prevalence of stunting, wasting, underweight, and overweight were 21.2%, 2.6%, 7.4%, and 2.6%, respectively. In multivariable regressions, risk of stunting significantly increased by age: 5.3% at <6 months (reference), 16.8% at 6–23 months (OR = 3.06, 95% CI [0.63, 14.8]), and 25.0% at 24–59 months (OR = 5.07, [1.16, 22.2]). Risk of stunting also decreased in a dose–response manner with improved maternal education. None of the examined variables were significantly associated with wasting or overweight. Despite a WHZ distribution comparable with the World Health Organization reference (with ~2.6% vs. an expected 2.5% of children beyond 2 z in each tail), stunting persists in one fifth of preschool Bhutanese children, suggesting that other nutrient deficits or nonnutritional factors may be constraining linear growth for a substantial proportion of children.

C. A, Manohar S, Shrestha B, Nonyane BAS, Neupane S, Bhandari S, Klemm RD, Webb P, West KP. Nutritional resilience in Nepal following the earthquake of 2015

Background

The 2015 earthquake in Nepal caused massive damages and triggered relief activities to minimize human suffering. The post-earthquake nutrition and food security situation in the hardest hit areas remains uncertain.

Methods

Two national cross-sectional surveys were conducted in 2014 and 2016 among households (HH) with pre-school aged children or newly married women. Of the 21 village development committees (VDCs) included in this sample, 7 fell within “earthquake-affected” areas. This paper presents data from 982 HH, 1015 women, and 883 children from 2014 and 1056 HH, 1083 women, and 998 children from 2016 living in these areas, with longitudinal overlap of about 55%. Prevalence estimates and 95% confidence intervals were calculated, and logistic regression was used to calculate p-values, both using robust estimates of standard errors to account for clustering.

Results

From 2014 to 2016, child wasting (weight-for-height z score <-2) fell from 4.5% (95% CI 3.3%– 6.1%) to 2.1% (1.4%– 3.1%) and food insecurity (assessed using the household food insecurity access scale) dropped from 17.6% (11.7%– 25.6%) to 12.4% (6.9%– 21.2%). Child stunting prevalence remained similar at both time-points. Improvements were also evident in dietary diversity and breastfeeding indicators.

Conclusions

Nutrition and food security conditions remained comparable or improved one year after the earthquake despite evidence of structural and other damage. Livelihood resilience to shocks and/or effective nutrition, food or health interventions may have helped buffer the impact on nutrition, although this hypothesis requires further exploration.

Seasonality of Consumption of Nonstaple Nutritious Foods among Young Children from Nepal's 3 Agroecological Zones

BACKGROUND

Children's dietary patterns vary seasonally, particularly in subsistence agriculture settings like Nepal, but the seasonality of nutritious nonstaple food consumption is not well explored in the literature.

OBJECTIVE

This study aimed to examine seasonal differences in children's consumption of provitamin A-rich fruit and vegetables, dairy, eggs, meat, and fish in Nepal's 3 agroecological zones, and to assess whether seasonal patterns vary by wealth and caste/ethnicity.

METHODS

Multivariable negative binomial regression models were used to analyze dietary data from 7-d food-frequency questionnaires, producing coefficient estimates in the form of incidence rate ratios (IRRs). Data were collected 3 times per year for 2 y from children aged 6-72 mo in Nepal's mountains (n = 226), hills (n = 168), and plains (n = 225).

RESULTS

There were significant seasonal differences in children's consumption of provitamin A-rich fruit and vegetables, dairy, meat, and fish that varied by agroecological zone. Adopting monsoon season as the referent for all comparisons, children in the mountains ate provitamin A-rich fruit and vegetables less frequently during the postmonsoon and winter seasons (IRRs: 0.5 and 0.7, respectively; both P < 0.004), whereas in the plains, children's consumption of these foods was lower only during the postmonsoon season (IRR: 0.2; P < 0.001). Children's dairy intake frequency increased during the winter in the mountains (IRR: 0.7; P < 0.004) and decreased during the winter in the hills (IRR: 1.5; P < 0.001). Only in the plains did children's meat and fish intakes vary seasonally, increasing during the postmonsoon season (IRR: 1.6; P < 0.004). Wealth and caste/ethnicity variability influenced children's consumption of each of these nutritious groups of foods, and moderated seasonal effects in some instances.

CONCLUSIONS

Children's diets varied differently by season within each agroecological zone of Nepal and in some cases across socioeconomic groups, revealing the importance of taking a season- and location-specific approach to assessing diets and tailoring dietary strategies.

The co-occurrence of anaemia and stunting in young children

Anaemia and stunting are prevalent nutritional problems among children of low-income countries that have profound effects on development, morbidity, and mortality. Many use a single conceptual framework to identify the basic determinants of these and other forms of malnutrition. One would expect that problems with matching underlying determinants should co-occur in affected individuals to a greater degree than by chance. In 2 populations of children-ages 6-18 months in Bihar, India, (n = 5,664) and 6-36 months in Lambayeque, Peru (n = 688)-we measured the frequency of the co-occurrence of anaemia and stunting. We compared this value with the value expected by chance, the product of the prevalence of anaemia and stunting, using a chi-square test. We also built logistic regression models for each condition. The frequency of co-occurrence in the Indian population was 21.5%, and in the Peruvian population, it was 30.4%, which are similar to frequencies expected by chance, 21.3% (p = .97) and 31.5% (p = .85). In Peru, anaemia was associated with age and consumption of treated water. Stunting was associated with age, sex, dietary diversity, hand washing, language spoken, and wealth. In India, anaemia was associated with age, sex, caste, dietary diversity, and household hunger. Stunting was associated with age, sex, caste, wealth, and maternal illiteracy. Despite some basic shared factors, anaemia and stunting are more independent than commonly assumed. Interventions that target children based on 1 condition may miss children with the other form of malnutrition.

Does physiological distribution of blood parameters in children depend on socioeconomic status? Results of a German cross-sectional study

OBJECTIVES

In the present study, we examined the relation between socioeconomic status (SES) and the physiological distribution of iron-related blood parameters.

DESIGN

This is a cross-sectional analysis of longitudinal population-based cohort study.

SETTING

Based on a sample of healthy participants from a German research centre, various blood parameters and values of clinical examinations and questionnaires were collected.

PARTICIPANTS

A total of 1206 healthy volunteers aged 2.5 to 19 years, one child per family randomly selected, were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Associations between the SES of children by Winkler-Stolzenberg Index (WSI) and its dimensions (income, education, occupation) and iron-related blood parameters (haemoglobin, ferritin and transferrin) were analysed by linear regression analyses. Gender and pubertal stage were included as covariables. Additionally, associations between SES of children by WSI and physical activity (side-to-side jumps, push-ups) as well as body mass index (BMI) were analysed by linear regression analyses.

RESULTS

Children with high WSI or family income showed significantly increased z-scores for haemoglobin (P=0.046; P<0.001). Children with increased WSI or family income showed significantly lower z-scores for transferrin (P<0.001). There was a significant correlation between haemoglobin and gender (P<0.001) and between transferrin and pubertal stage (P=0.024). Furthermore, physical activity was positively correlated and BMI was negatively correlated with WSI (P<0.001).

DISCUSSION

Our data show an association between SES and the distribution of iron-dependent parameters. Lower SES is correlated with lower values for haemoglobin and higher values for transferrin. Furthermore, we demonstrate that physical activity and BMI are associated with SES. Whereas higher SES is correlated with higher values for physical activity and lower BMI. Our parameters are standardised as z-scores with the advantages that the results are comparable across different age groups and present physiological courses.

Individual, household, and community level risk factors of stunting in children younger than 5 years: Findings from a national surveillance system in Nepal

Despite substantial reductions in recent years in Nepal, stunting prevalence in children younger than 5 years remains high and represents a leading public health concern. To identify factors contributing to the stunting burden, we report multilevel risk factors associated with stunting in 4,853 children aged 6-59 months in a nationally and agroecologically representative random sample from the first year of the Policy and Science for Health, Agriculture, and Nutrition Community Studies, a community-based observational, mixed-panel study. Mixed effects logistic regressions controlling for multilevel clustering in the study design were used to examine the association of individual-, household-, and community-level factors associated with stunting. Stunting prevalence was 38% in our sample. After adjustment for potential confounding variables, maternal factors, including maternal height and education, were generally the strongest individual-level risk factors for stunting, adjusted odds ratio (AOR) = 2.52, 95% CI [1.96, 3.25], short (<145 cm) versus not short mothers; AOR = 2.09, 95% CI [1.48, 2.96], uneducated mothers versus secondary school graduates. Among the household- and community-level factors, household expenditure and community infrastructure (presence of paved roads, markets, or hospitals) were strongly, inversely associated with increased stunting risk, AOR = 1.68, 95% CI [1.27, 2.24], lowest versus highest household expenditure quintile; AOR = 2.38, 95% CI [1.36, 4.14], less developed (lacking paved roads, markets, or hospitals) versus more developed communities. Although most factors associated with stunting are not rapidly modifiable, areas for future research and possible interventions emerged.

Household food production is positively associated with dietary diversity and intake of nutrient-dense foods for older preschool children in poorer families: Results from a nationally-representative survey in Nepal

BACKGROUND

Nutrition-sensitive interventions supporting enhanced household food production have potential to improve child dietary quality. However, heterogeneity in market access may cause systematic differences in program effectiveness depending on household wealth and child age. Identifying these effect modifiers can help development agencies specify and target their interventions.

OBJECTIVE

This study investigates mediating effects of household wealth and child age on links between farm production and child diets, as measured by production and intake of nutrient-dense food groups.

METHODS

Two rounds (2013 and 2014) of nationally representative survey data (n = 5,978 observations) were used to measure production and children's dietary intake, as well as a household wealth index and control variables, including breastfeeding. Novel steps used include measuring production diversity in terms of both species grown and food groups grown, as well as testing for mediating effects of family wealth and age of child.

RESULTS

We find significant associations between child dietary diversity and agricultural diversity in terms of diversity of food groups and of species grown, especially for older children in poorer households, and particularly for fruits and vegetables, dairy and eggs. With each additional food group produced, log-odds of meeting minimum dietary diversity score (≥4) increase by 0.25 (p = 0.01) for children aged 24-59 months. For younger children aged 18-23 months there is a similar effect size but only in the poorest two quintiles of household wealth, and for infants 6-18 months we find no correlation between production and intake in most models.

CONCLUSIONS

Child dietary intake is associated with the composition of farm production, most evident among older preschool children and in poorer households. To improve the nutrition of infants, other interventions are needed; and for relatively wealthier households, own farm production may displace market purchases, which could attenuate the impact of household production on child diets.

Household cereal crop harvest and children's nutritional status in rural Burkina Faso

BACKGROUND

Reduction of child undernutrition is one of the Sustainable Development Goals for 2030. Achievement of this goal may be made more difficult in some settings by climate change through adverse impact on agricultural productivity. However, there is only limited quantitative evidence on the link between household crop harvests and child nutrition. We examined this link in a largely subsistence farming population in rural Burkina Faso.

METHODS

Data on the middle-upper arm circumference (MUAC) of 975 children ≤5 years of age, household crop yields, and other parameters were obtained from the Nouna Health and Demographic Surveillance System. Multilevel modelling was used to assess the relationship between MUAC and the household crop harvest in the year 2009 estimated in terms of kilocalories per adult equivalent per day (kcal/ae/d).

RESULTS

Fourteen percent of children had a MUAC <125 mm (a value indicative of acute undernutrition). The relationship between MUAC and annual household food energy production adjusted for age, sex, month of MUAC measurement, household wealth, whether a household member had a non-agricultural occupation, garden produce, village infrastructure and market presence, suggested a decline in MUAC below around 3000 kcal/ae/d. The mean MUAC was 2.49 (95% CI 0.45, 4.52) mm less at 1000 than at 3000 kcal/ae/d.

CONCLUSIONS

Low per capita household crop production is associated with poorer nutritional status of children in a rural farming population in Burkina Faso. This and similar populations may thus be vulnerable to the adverse effects of weather on agricultural harvest, especially in the context of climate change.
