Abstract Suboptimal complementary feeding practices contribute to a rapid increase in the prevalence of stunting young children from age 6 months. The design effective programmes improve infant and child requires sound understanding local situation systematic process for prioritizing interventions, integrating them into existing delivery platforms monitoring their implementation impact. identification adequate food‐based recommendations that respect locally available foods address gaps...

In Bangladesh, many programs and projects have been promoting breastfeeding since the late 1980 s. Breastfeeding practices, however, not improved accordingly. For identifying program-relevant issues to improve in infancy, quantitative data were collected through visits households (n = 356) rural Chittagong urban slums Dhaka, qualitative from sub-samples by applying semi-structured in-depth interviews 42), focus group discussions 28), opportunistic observations 21). Trials of Improved...

Background Spina bifida and anencephaly are two major neural tube defects. They contribute substantially to perinatal, neonatal, infant, under‐five mortality life‐long disability. To monitor the progress toward total prevention of folic acid‐preventable spina (FAP SBA), we examined their global status in 2015. Methods Based on existing data, modeled proportion FAP SBA that prevented year 2015 through mandatory acid fortification globally. We included only those countries with added at least...

Abstract To reduce micronutrient deficiencies, Senegal mandates the fortification of refined oil with vitamin A and wheat flour iron folic acid. Expanding Senegal's large‐scale food programs to include fortified bouillon could help fill remaining gaps in dietary requirements. Using 7‐day household consumption data collected between 2018 2019, we assessed potential contributions (40–250 μg/g bouillon), acid (20–120 μg/g), B12 (0.2–2 (0.6–5 mg/g), zinc mg/g) for meeting requirements women...

Overweight and underweight increase the risk of metabolic impairments chronic disease. Interventions at household level require diagnosis nutritional status among family members. The aim this study was to describe prevalence patterns various anthropometric typologies over a decade in Colombia using novel approach that considers all children as well mother. This also allows identifying dual burden malnutrition within household, where one child may be overweight another undernourished.

Abstract Background Mandatory folic acid fortification of staples is a proven intervention to prevent spina bifida and anencephaly, two life‐threatening disabling neural tube defects. We estimated the global proportion acid‐preventable anencephaly (FAP SBA) prevented through mandatory wheat and/or maize flour in 2019. Methods Using data from Global Fortification Data Exchange, we identified countries with policies that required at least 1.0 ppm be added had information on percentage...

Spina bifida and anencephaly are major neural tube defects largely preventable through maternal periconceptional intake of folic acid. We estimated the global proportion acid-preventable spina (FAP SBA) prevented mandatory acid fortification cereal grains, including wheat flour, maize rice, at end year 2020, a time point marking 30th anniversary publication landmark British Medical Research Council (MRC) study providing unequivocal knowledge on acid's FAP SBA prevention potential.The Food...

We anemia using following 2 main categories: 1) those nutrients alone, and, 2)...

Background Child undernutrition remains high in South Asian and sub-Saharan African countries. Rapid declines nutritional status occur before the age of 2 years, particularly during period complementary feeding. Improving feeding practices is a neglected area nutrition programs. Objective To understand community perspectives on order to inform design future interventions for improved Methods From May through August 2009, data were collected two rural locations one urban location Bangladesh...

This study assessed barriers to exclusive breastfeeding in rural Viet Nam and identified how a few mothers were able exclusively breastfeed despite barriers. A cross-sectional quantitative qualitative assessment was carried out among 120 of infants less than six months old northern Nam. Only 24% the breastfed. Adjusting for infant's age who attended delivery, risk not 14.0 times greater women had returned work not. Exclusively (n = 4) worked differed from other important ways. They all felt...

Context-specific evidence evaluation is advocated in modern epidemiology to support public health policy decisions, avoiding excessive reliance on experimental study designs. Here we present the rationale for a paradigm shift of derived from independent studies, as well systematic reviews and meta-analyses observational applying Hill's criteria (including coherence, plausibility, temporality, consistency, magnitude effect, dose-response) evaluate food fortification an effective intervention...
