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, ) 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.

Background: The World Health Organization (WHO) recommends balanced energy and protein (BEP) supplementation be provided to all pregnant women living in undernourished populations, usually defined as having a prevalence > 20% of underweight women, to reduce the risk of stillbirths and small-for-gestational-age neonates. Few geographies meet this threshold, however, and a large proportion of undernourished women and those with inadequate gestational weight gain could miss benefiting from BEP. This study compares the effectiveness of individual targeting approaches for supplementation with micronutrient-fortified BEP vs.

Background: Early and exclusive breastfeeding may reduce neonatal and post-neonatal mortality in low-resource settings. However, prelacteal feeding (PLF), the practice of giving food or liquid before breastfeeding is established, is still a barrier to optimal breastfeeding practices in many South Asian countries. We used a prospective cohort study to assess the association between feeding non-breastmilk food or liquid in the first three days of life and infant size at 3-5 months of age.

Balanced energy protein (BEP) supplementation is an efficacious intervention in pregnancy for improving birthweight and is recommended by World Health Organization (WHO) in countries with high maternal undernutrition. Few countries have implemented BEP programmes due in part to high cost, lack of data on acceptability and feasibility, and complexity of delivery. We sought to address implementation gaps in BEP interventions through a formative study designed to understand implementation outcomes.

Balanced energy protein (BEP) supplementation in pregnancy is recommended in the context of undernutrition for the reduction of small-for-gestational age neonates and stillbirths. To inform an effectiveness trial, we evaluated the acceptability of a packaged, ready-to-eat fortified BEP product among women of reproductive age and their health care providers (HCPs) in rural Bangladesh and explored the feasibility of adhering to daily supplementation. We implemented a formative study using focus groups discussions with women (n = 29) and HCPs (n = 17) to introduce the product and investigate components of acceptability.

Objective: An annualised linear growth velocity (LGV) reference can identify groups of children at risk of growing poorly. As a single velocity reference for all preschool ages does not exist, we present an interim tool, derived from published, normative growth studies, for detecting growth faltering, illustrating its use in Nepali preschoolers.

Design: The WHO Child Growth Velocity Standard was adapted to derive 12-month increments and conjoined to the Tanner-Whitehouse Height Velocity Reference data yielding contiguous preschool linear growth annualised velocities.

Article Synopsis
  • The study examines how social desirability bias affects the accuracy of pregnant women's recall of antenatal care services in rural Southern Nepal.
  • A longitudinal study involving 401 pregnant women compared recalled antenatal care against direct observations, finding that social desirability scores had limited influence on most care types but did improve recall accuracy for nausea counseling.
  • The presence of family members during interviews led to significant overestimations of ANC visits, suggesting that interviews should ideally be conducted in private to enhance accuracy.

This study explores common factors associated with not meeting minimum dietary diversity (MDD) among 27,072 children aged 6-23 months in Eastern and Southern Africa using data from nine Demographic and Health Surveys from 2013 to 2016. MDD was defined as consumption of more than or equals to five of eight food groups including breast milk in the past 24 h. Equity gaps were calculated as the difference in MDD prevalence between the top and bottom wealth quintiles.

Infant and young child feeding (IYCF) practices are influenced by many context-specific factors related to local food systems as well as social and cultural practices. Understanding these local contextual perspectives is essential for designing effective programs and policies. This paper uses focused ethnographic study methods to examine challenges experienced by mothers related to IYCF in two counties in Kenya, a country with considerable heterogeneity in agriculture, food systems, and cultures.

Inadequate diet among children has both immediate and long-term negative health impacts, but little is known about dietary diversity and dietary patterns of school-aged children in rural Kenya. We assessed dietary diversity and identified dietary patterns in school-aged children in Western Kenya using a latent class approach. We collected dietary intake using a 24 h dietary recall among students in elementary schools in two rural villages (hereafter village A and B) in Western Kenya in 2013.

Article Synopsis
  • Fish are crucial for providing essential nutrients and fatty acids, helping to reduce dietary deficiencies globally.
  • Research indicates that foreign fishing activities contribute more nutrients to nutrient-secure countries compared to international fish trade, with both practices benefiting these nations disproportionately.
  • To effectively tackle nutrient deficiencies, it's essential to prioritize nutritional goals in fisheries licensing and trade discussions, especially considering the vulnerabilities of certain nations due to climate change impacts.

Antenatal multiple micronutrient supplements (MMS) are more effective than iron and folic acid (IFA) supplements in reducing adverse pregnancy outcomes. Questions remain, however, about the ability of MMS to prevent anemia as effectively as IFA, especially at a lower dose of daily iron and in areas of high anemia prevalence. Analyzing data from 11 trials from a recent Cochrane review, we compared MMS to IFA, delivering either 30 or 60 mg of iron, in sustaining hemoglobin and preventing third trimester anemia and iron deficiency anemia (IDA), accounting for daily iron dose, total supplemental iron intake, and baseline prevalence of anemia.

The "second 1000 days" is a period of rapid brain growth which consolidates developmental foundations and establishes school readiness. Understanding the relation between household characteristics, child diet, and child development remains incomplete, especially in resource-poor settings where >250 million children risk not achieving their full developmental potential. Child developmental performance was assessed (Ages & Stages Questionnaire [ASQ]) at ages 2 and 5 years in a cohort of Nepali children (n = 207) whose families participated in a nutrition/livestock management+community development intervention trial.
