Infant and young child feeding practices and child linear growth in Nepal : regression-decomposition analysis of national survey data, 1996–2016

Suboptimal infant and young child feeding (IYCF) practices have profound implications on child survival, health, growth, and development. First, our study analysed trends in 18 IYCF indicators and height-for-age z-score (HAZ) and stunting prevalence across Nepal's Family Health Survey 1996 and four rounds of Nepal Demographic and Health Surveys from 2001-2016. Second, we constructed multivariable regression models and decomposed the contribution of optimal IYCF practices on HAZ and stunting prevalence over the 1996-2016 period. Our findings indicate that most age-appropriate IYCF practices and child linear growth outcomes improved over the past two decades. At present, according to the World Health Organization's tool for national assessment of IYCF practices, duration of breastfeeding is rated very good, early initiation of breastfeeding and exclusive breastfeeding (EBF) are rated good, whereas minimal bottle-feeding and introduction of solid, semi-solid or soft foods are rated fair. Our study also reports that a paucity of age-appropriate IYCF practices-in particular complementary feeding-are significantly associated with increased HAZ and decreased probability of stunting (p < .05). Moreover, age-appropriate IYCF practices-in isolation-made modest statistical contributions to the rapid and sustained reduction in age-specific child linear growth faltering from 1996-2016. Nevertheless, our findings indicate that comprehensive multisectoral nutrition strategies-integrating and advocating optimal IYCF-are critical to further accelerate the progress against child linear growth faltering. Furthermore, specific focus is needed to improve IYCF practices that have shown no significant development over the past two decades in Nepal: EBF, minimum acceptable diet, and minimal bottle-feeding

Elucidating the sustained decline in under‐three child linear growth faltering in Nepal, 1996-2016

Childhood linear growth faltering remains a major public health concern in Nepal. Nevertheless, over the past 20 years, Nepal sustained one of the most rapid reductions in the prevalence of stunting worldwide. First, our study analysed the trends in height-for-age z-score (HAZ), stunting prevalence, and available nutrition-sensitive and nutrition-specific determinants of linear growth faltering in under-three children across Nepal's Family Health Survey 1996 and Nepal's Demographic and Health Surveys 2001, 2006, 2001, and 2016. Second, we constructed pooled multivariable linear regression models and decomposed the contributions of our time-variant determinants on the predicted changes in HAZ and stunting over the past two decades. Our findings indicate substantial improvements in HAZ (38.5%) and reductions in stunting (-42.6%) and severe stunting prevalence (-63.9%) in Nepalese children aged 0-35 months. We also report that the increment in HAZ, across the 1996-2016 period, was significantly associated (confounder-adjustedp< .05) with household asset index, maternal and paternal years of education, maternal body mass index and height, basic child vaccinations, preceding birth interval, childbirth in a medical facility, and prenatal doctor visits. Furthermore, our quantitative decomposition of HAZ identified advances in utilisation of health care and related services (31.7% of predicted change), household wealth accumulation (25%), parental education (21.7%), and maternal nutrition (8.3%) as key drivers of the long-term and sustained progress against child linear growth deficits. Our research reiterates the multifactorial nature of chronic child undernutrition and the need for coherent multisectoral nutrition-sensitive and nutrition-specific strategies at national scale to further improve linear growth in Nepal

Obesity and Risk Knowledge

Obesity is an epidemic health problem in many developed countries, and it is an emerging public health concern in developing, transitional, and newly-developed countries. The purpose of this research is to investigate the relationship between individuals' knowledge concerning the health risks of obesity and their tendency to be obese (as measured by the \body mass index"). Instead of assuming that obesity is a pure physiological problem as in previous studies, we allow an individual's cost/bene¯t evaluation to play a role. Based on survey data from Taiwan, we investigate the relationship with the quantile regression technique. The results suggest that such a relationship does exist and it is di®erent for males and females.Obesity, Overweight, Risk Knowledge, Quantile Regression

Levels and Determinants of DDT and DDE Exposure in the VHEMBE Cohort.

BackgroundAlthough indoor residual spraying (IRS) is an effective tool for malaria control, its use contributes to high insecticide exposure in sprayed communities and raises concerns about possible unintended health effects.ObjectiveThe Venda Health Examination of Mothers, Babies and their Environment (VHEMBE) is a birth cohort study initiated in 2012 to characterize prenatal exposure to IRS insecticides and exposures' impacts on child health and development in rural South Africa.MethodsIn this report, we describe the VHEMBE cohort and dichlorodiphenyltrichloroethane (DDT) and dichlorodiphenyldichloroethylene (DDE) serum concentrations measured in VHEMBE mothers when they presented for delivery. In addition, we applied a causal inference framework to estimate the potential reduction in population-level p,p'-DDT and p,p'-DDE serum concentrations under five hypothetical interventions. A total of 751 mothers were enrolled.ResultsSerum concentrations of p,p' isomers of DDT and DDE were above the limit of detection (LOD) in ≥98% of the samples, whereas the o,p' isomers were above the LOD in at least 80% of the samples. Median (interquartile range) p,p'-DDT and p,p'-DDE serum concentrations for VHEMBE cohort participants were 55.3 (19.0-259.3) and 242.2 (91.8-878.7) ng/g-lipid, respectively. Mothers reporting to have lived in a home sprayed with DDT for malaria control had ~5-7 times higher p,p'-DDT and p,p'-DDE serum concentrations than those who never lived in a home sprayed with DDT. Of the five potential interventions tested, we found increasing access to water significantly reduced p,p'-DDT exposure and increasing the frequency of household wet mopping significantly reduced p,p'-DDT and p,p'-DDE exposure.ConclusionOur findings suggest that several intervention approaches may reduce DDT/DDE exposure in pregnant women living in IRS communities. https://doi.org/10.1289/EHP353

Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective

This Report has a number of inter-related general purposes. One is to explore the extent to which food, nutrition, physical activity, and body composition modify the risk of cancer, and to specify which factors are most important. To the extent that environmental factors such as food, nutrition, and physical activity influence the risk of cancer, it is a preventable disease. The Report specifies recommendations based on solid evidence which, when followed, will be expected to reduce the incidence of cancer

No. 07: Rapid Urbanization and the Nutrition Transition in Southern Africa

The nutrition transition, including the presence of malnutrition and obesity in poor urban populations (the so-called ‘double burden’ of disease), is occurring in Southern Africa in the context of massive rural-urban migration and rapid urbanization. This seemingly contradictory situation poses one of the major threats to public health in the developing world, and impacts the poor – and therefore the most food insecure – to the greatest extent. This paper reviews the state of knowledge about food insecurity and the nutrition transition in the urban areas of Southern Africa drawing on existing studies and new research conducted by AFSUN. The paper lays out an agenda for future research on nutrition environments and discusses the implications of undernutrition and overnutrition for urban policy making on health and food security in the region

Determinants of Mammography Usage across Rural and Urban Regions of Canada

Breast cancer is a leading source of mortality among Canadian women; however early detection via mammography considerably improves survival rates. Accordingly, national guidelines advocate biennial screening for asymptomatic women aged 50 to 69 years. Unfortunately many women do not abide by such recommendations, and there is some evidence that compliance rates are lower in rural areas. This report explores the extent of regional variation within and between Canadian provinces using a new and more detailed set of rural indicators based on economic zones of influence. We find the incidence of ever having a mammogram and screening within the last two years are significantly lower for women most removed from large urban centers. This result is obtained after controlling for demographic and socio-economic characteristics, concentration of physicians and specialists in the local area and whether the woman has a regular family doctor. An important reason for the observed differences across rural and urban areas is found to be awareness of the need for regular screening. We also observe that differences in mammography usage between rural and urban areas vary significantly across Canadian provinces.mammography, cancer screening, rural health, women's health

An energy-saving development initiative increases birth rate and childhood malnutrition in rural Ethiopia

Background: Evolutionary life history theory predicts that, in the absence of contraception, any enhancement of maternal condition can increase human fertility. Energetic trade-offs are likely to be resolved in favour of maximizing reproductive success rather than health or longevity. Here we find support for the hypothesis that development initiatives designed to improve maternal and child welfare may also incur costs associated with increased family sizes if they do not include a family planning component. Methods and Findings: Demographic and anthropometric data were collected in a rural Ethiopian community benefiting from a recent labour-saving development technology that reduces women's energetic expenditure (n = 1,976 households). Using logistic hazards models and general linear modelling techniques, we found that whilst infant mortality has declined, the birth rate has increased, causing greater scarcity of resources within households. Conclusions: This study is, to our knowledge, the first to demonstrate a link between a technological development intervention and an increase in both birth rate and childhood malnutrition. Women's nutritional status was not improved by the energy-saving technology, because energy was diverted into higher birth rates. We argue that the contribution of biological processes to increased birth rates in areas of the developing world without access to modern contraception has been overlooked. This highlights the continued need for development programmes to be multisectoral, including access to and promotion of contraception
