BackgroundStunting in early life has considerable human and economic costs. The purpose of the study was to identify factors associated with stunting among children aged 0-23 months in Indonesia to inform the design of appropriate policy and programme responses.MethodsDeterminants of child stunting, including severe stunting, were examined in three districts in Indonesia using data from a cross-sectional survey conducted in 2011. A total of 1366 children were included. The analysis used multiple logistic regression to determine unadjusted and adjusted odds ratios.ResultsThe prevalence of stunting and severe stunting was 28.4 % and 6.7 %, respectively. The multivariate analysis on determinants of stunting identified a significant interaction between household sanitary facility and household water treatment (P for interaction = 0.007) after controlling for potential covariates: in households that drank untreated water, the adjusted odds on child stunting was over three times higher if the household used a unimproved latrine (adjusted odds ratio 3.47, 95 % confidence interval 1.73-7.28, P <0.001); however, in households that drank treated water, the adjusted odds on child stunting was not significantly higher if the household used an unimproved latrine (adjusted odds ratio 1.27, 95 % confidence interval 0.99-1.63, P = 0.06). Other significant risk factors included male sex, older child age and lower wealth quintile. The risk factors for severe stunting included male sex, older child age, lower wealth quintile, no antenatal care in a health facility, and mother’s participation in decisions on what food was cooked in the household.ConclusionsThe combination of unimproved latrines and untreated drinking water was associated with an increased odds on stunting in Indonesia compared with improved conditions. Policies and programmes to address child stunting in Indonesia must consider water, sanitation and hygiene interventions. Operational research is needed to determine how best to converge and integrate water, sanitation and hygiene interventions into a broader multisectoral approach to reduce stunting in Indonesia.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3339-8) contains supplementary material, which is available to authorized users.
Macroeconomic food policies have the potential to reduce malnutrition by improving access to food, a determinant of nutritional status. However, very little is understood about the mechanisms and the magnitude of the effects of macroeconomic food policies such as food price policies on nutritional status. Data collected by the Nutritional Surveillance Project on a total of 81,337 children aged 6-59 mo in rural Bangladesh between 1992 and 2000 were used to examine how changes in rice price affect child underweight. Rice consumption per capita declined only slightly during the period but rice expenditure per capita varied widely due to fluctuations in rice price. Rice expenditure was positively correlated with the percentage of underweight children (r = 0.91, P = 0.001). Households were found to spend more on nonrice foods as their rice expenditure declined, and nonrice expenditure per capita was negatively correlated with the percentage of underweight children (r = -0.91, P = 0.001). Expenditure on nonrice foods per capita increased with the frequency with which nonrice foods were consumed (P < 0.05) and with the diversity of the diet (P < 0.001). The findings suggest that the percentage of underweight children declined when rice expenditure fell because households were able to spend more on nonrice foods and thereby increase the quantity and quality of their diet. We hypothesize that macroeconomic food policies that keep the price of food staples low can contribute toward reducing child underweight.
WHO recommends that anthelmintic treatment be included in strategies to improve maternal nutrition in areas where hookworms are endemic and anaemia is prevalent. At present, few countries have adopted this recommendation, partly owing to the lack of data to support the adverse effects of hookworms on maternal health. A longitudinal study was conducted on 125 women in Sierra Leone (in 1995/96) to measure the impact of single-dose albendazole (400 mg) and daily iron-folate supplements (36 mg iron and 5 mg folate) on haemoglobin and serum ferritin concentration during pregnancy. Women who received both albendazole and iron-folate supplements experienced no significant change (P > 0.05) in the prevalence of anaemia and iron-deficiency anaemia between the first and third trimesters. These prevalence levels significantly increased (P < 0.05) in women who received either albendazole or iron-folate supplements or neither. After controlling for baseline haemoglobin concentration and season, the mean decline in haemoglobin concentration between the first and third trimester in women who received albendazole was 6.6 g/L less than in women who received the control (P = 0.0034). The corresponding value for iron-folate supplements was 13.7 g/L haemoglobin (P < 0.001). The effects of albendazole and iron-folate supplements were additive. These findings lend support to WHO's recommendation for anthelmintic treatment during pregnancy.
Optimal breastfeeding practices, including early initiation of breastfeeding (EIBF) within 1 hr of birth, exclusive breastfeeding (EBF) for the first 6 months of age, and continued breastfeeding (CBF) for 2 years of age or beyond with appropriate complementary foods, are essential for child survival, growth, and development. Breastfeeding norms differ within and between countries in South Asia, and evidence is needed to inform actions to protect, promote, and support optimal practices. This study examines time trends and predictors of EIBF, avoidance of prelacteal feeding (APF), EBF, and CBF to 2 years using survey data from Afghanistan, Bangladesh, India, Nepal, and Pakistan since 1990. EIBF, APF, and EBF increased in Bangladesh, India, and Nepal from 1990 to 2016. EIBF and EBF increased in Pakistan from 1990 to 2013, but both EIBF and APF decreased in recent years. In Afghanistan, EIBF, APF, and EBF decreased from 2010 to 2015. CBF remained fairly constant across the region although prevalence varied by country. Significant ( p < 0.05) predictors of suboptimal practices included caesarian delivery (4–25%), home delivery, small size at birth, and low women's empowerment. Wealth, ethnic group, and caste had varied associations with breastfeeding. Progress towards optimal breastfeeding practices is uneven across the region and is of particular concern in Afghanistan and Pakistan. There are some common predictors of breastfeeding practices across the region, however country‐specific predictors also exist. Policies, programs, and research should focus on improving breastfeeding in the context of women's low empowerment and strategies to support breastfeeding of infants born small or by caesarian section, in addition to country‐specific actions.
Micronutrient malnutrition is a key driver of morbidity and mortality for millions of children in South Asia. Understanding the specific micronutrients lacking in the diet during the complementary feeding period is essential for addressing undernutrition caused by inadequate diets. A Comprehensive Nutrient Gap Assessment was used to synthesize diverse evidence and estimate the public health significance of complementary-feeding micronutrient gaps and identify evidence gaps in 8 countries in South Asia. There were important gaps across the region in iron, zinc, vitamin A, folate, vitamin B12, and, to a lesser extent, calcium and vitamin C. The most nutrient-dense, whole-food sources of these micronutrients include liver, small fish, eggs, ruminant meat, and dark leafy greens. Investment is needed in some countries to collect data on micronutrient biomarkers and dietary intakes. A food systems approach is essential for improving child diets and reducing malnutrition, which affects millions of children, their futures, and society at large across South Asia and beyond.
