Association between household unavailability of iodized salt and child growth: evidence from 89 demographic and health surveys

Abstract Background Peru has historically experienced high rural-to-urban migration. Despite large reductions in undernutrition, overweight is increasing. Elsewhere, internal migration has been associated with differences in children’s growth and nutritional health. We investigated how child growth and nutritional status in Peru varied over time and in association with maternal internal migration. Methods Using data from Demographic & Health Surveys from 1991 to 2017, we assessed trends in child growth (height-for-age [HAZ], weight-for-age [WAZ], weight-for-height [WHZ] z scores) and nutritional health (stunting, underweight, overweight) by maternal adult internal migration (urban [UNM] or rural non-migrant [RNM], or urban-urban [UUM], rural-urban [RUM], rural-rural [RRM], or urban-rural migrant [URM]). Using 2017 data, we ran regression analyses, adjusting for confounders, to investigate associations of maternal migration with child outcomes and the maternal and child double burden of malnutrition. We further stratified by timing of migration, child timing of birth and, for urban residents, type of area of residence. Results are given as adjusted predictive margins (mean z score or %) and associated regression p-values [p]. Results In 1991–2017, child growth improved, and undernutrition decreased, but large differences by maternal migration persisted. In 2017, within urban areas, being the child of a migrant woman was associated with lower WHZ (UUM = 0.6/RUM = 0.5 vs UNM = 0.7; p = 0.009 and p < 0.001 respectively) and overweight prevalence ((RUM 7% vs UNM = 11% [p = 0.002]). Results however varied both by child timing of birth (birth after migration meant greater overweight prevalence) and type of area of residence (better linear growth in children of migrants [vs non-migrants] in capital/large cities and towns but not small cities). In rural areas, compared to RNM, children of URM had higher HAZ (− 1.0 vs − 1.2; p < 0.001) and WAZ (− 0.3 vs − 0.4; p = 0.001) and lower stunting (14% vs 21%; [p < 0.001]). There were no differences by timing of birth in rural children, nor by time since migration across all children. The mother and child double burden of malnutrition was higher in rural than urban areas but no differences were found by maternal internal migration. Conclusions Migration creates a unique profile of child nutritional health that is not explained by maternal ethnic and early life factors, but which varies depending on the pathway of migration, the child timing of birth in relation to migration and, for urban dwellers, the size of the place of destination. Interventions to improve child nutritional health should take into consideration maternal health and migration history.

ObjectiveSocioeconomic inequalities in child growth failure (CGF) remain one of the main challenges in Ethiopia. This study examined socioeconomic inequalities in CGF and determinants that contributed to these inequalities in Ethiopia.MethodsThe Ethiopia Demographic and Health Surveys 2000 and 2016 data were used in this study. A pooled unweighted sample of the two surveys yielded 21514 mother–child pairs (10873 in 2000 and 10641 in 2016). We assessed socioeconomic inequalities in CGF indicators using the concentration curve and concentration index (CI). We then decomposed the CI to identify percentage contribution of each determinant to inequalities.ResultsSocioeconomic inequalities in CGF have increased in Ethiopia between 2000 and 2016. The CI increased from −0.072 and −0.139 for stunting, −0.088 and −0.131 for underweight and −0.015 and −0.050 for wasting between 2000 and 2016, respectively. Factors that mainly contributed to inequalities in stunting included geographical region (49.43%), number of antenatal care visits (31.40%) and child age in months (22.20%) in 2000. While in 2016, inequality in stunting was contributed mainly by wealth quintile (46.16%) and geographical region (−13.70%). The main contributors to inequality in underweight were geographical regions (82.21%) and wealth quintile (27.21%) in 2000, while in 2016, wealth quintile (29.18%), handwashing (18.59%) and access to improved water facilities (−17.55%) were the main contributors. Inequality in wasting was mainly contributed to by maternal body mass index (−66.07%), wealth quintile (−45.68%), geographical region (36.88%) and paternal education (33.55%) in 2000, while in 2016, wealth quintile (52.87%) and urban areas of residence (-17.81%) were the main driving factors.ConclusionsThis study identified substantial socioeconomic inequalities in CGF, and factors that relatively contributed to the disparities. A plausible approach to tackling rising disparities may involve developing interventions on the identified predictors and prioritising actions for the most socioeconomically disadvantaged groups.

The Status

Background: Iodine deficiency causes various health problems such as mental defects, goiter, reproductive damage, hypo and hyperthyroidism, stillbirth, abortion, congenital abnormalities, cretinism, mental retardation, muscle anomalies, and reduced work output. Although the adverse effects on health and socio-economic development are well known, they persisted as a public health problem worldwide. Salt iodization is recommended as a simple cost-effective method to prevent iodine deficiency disorders. This study aimed to determine the magnitude, trends, and determinants of iodized salt availability in the household in Ethiopia. Methods: The current study used the Ethiopian Demographic and Health Surveys conducted from 2000 to 2016 with a total of 57 939 households. Descriptive statistics were performed on selected background characteristics to provide an overall picture of the sample after considering sample weights. To ensure the representativeness of the sample we applied a complex sample design considering household weights, primary sampling units, and the strata associated with it. The Cochran–Armitage test was performed to assess the trend of iodized salt availability in the household. Multivariate logistic regression was used to determine the association between the dependent variable and independent variables. A significance level of .05 was chosen for all analyses. Results: The magnitude of iodized salt availability in the household was 28.45% in 2000, 54.34% in 2005, 15.42% in 2011, and 89.28% in 2016. Iodized salt availability increased from 28.45% [95% CI: 27.69-29.21] in 2000 to 89.28% [95% CI: 88.79-89.75] in 2016. Despite the decline from 2005 to 2011 in the percentage of households with iodized salt, overall, there was a significant increment from 2000 to 2016 in Ethiopia ( P-value <.001). There were differences in the status of salt iodization in the administrative region, wealth, family size, and ownership of radio or television. Conclusion: Remarkable progress has been made in Ethiopia regarding iodized salt availability in recent years. Besides the current efforts to achieve universal salt iodization, future interventions should prioritize specific groups like those with lower socioeconomic status and geographic areas with lower availability of iodized salt in the household.

Demand For Children

Abstract Nigeria has one of the highest fertility rates in Africa. Data from 2013 Demographic and Health Surveys indicate a virtual stagnation of fertility rate since 2003. Low contraceptive use and pronatalist attitudes are among the factors contributing to the high fertility rate in Nigeria. In this manuscript, we pooled data from three most recent waves of Demographic and Health Surveys to examine trends in demand for children over time and identify the factors associated with change in demand for children. The data show that demand for children has declined since 2003 although not monotonically so. Variables that were positively associated with increased likelihood of desiring no additional children were residence in the South-West (as opposed to residence in the North-Central), exposure to family planning (FP) messages on the mass media, number of children ever born, educational level, and urban residence. In contrast, uncertainty about fertility desire was more widespread in 2008 compared to 2013 although less widespread in 2003 than in 2013. The likelihood of being undecided about fertility desire was positively associated with discrepancies in family size desires between husband and wife, parity and Islamic religious affiliation. Programs should aim to increase access to effective contraceptive methods and promote demand for contraceptives as a way of fostering a sustainable reduction in demand for children. Furthermore, strategies that address uncertainty by fostering women’s understanding of the social and health implications of large family sizes are relevant.

Sampling Weights

Child wasting continues to be a major public health concern in South Asia, having a prevalence above the emergency threshold. This paper aimed to identify factors associated with wasting among children aged 0–23 months, 24–59 months, and 0–59 months in South Asia. A weighted sample of 564,518 children aged 0–59 months from the most recent demographic and health surveys (2014–2018) of five countries in South Asia was combined. Multiple logistic regression analyses that adjusted for clustering and sampling weights were used to examine associated factors. Wasting prevalence was higher for children aged 0–23 months (25%) as compared to 24–59 months (18%), with variations in prevalence across the South Asian countries. The most common factor associated with child wasting was maternal BMI [adjusted odds ratio (AOR) for 0–23 months = 2.02; 95% CI: (1.52, 2.68); AOR for 24–59 months = 2.54; 95% CI: (1.83, 3.54); AOR for 0–59 months = 2.18; 95% CI: (1.72, 2.77)]. Other factors included maternal height and age, household wealth index, birth interval and order, children born at home, and access to antenatal visits. Study findings suggest need for nutrition specific and sensitive interventions focused on women, as well as adolescents and children under 2 years of age.
