Provision of low‐aflatoxin local complementary porridge flour reduced urinary aflatoxin biomarker in children aged 6–18 months in rural Tanzania
Aflatoxins are toxic secondary metabolites of fungi that colonize staple food crops, such as maize and groundnut, frequently used in complementary feeding. In preparation for a large trial, this pilot study examined if provision of a low-aflatoxin infant porridge flour made from local maize and groundnuts reduced the prevalence of a urinary aflatoxin biomarker in infants. Thirty-six infants aged 6-18 months were included from four villages in Kon…
The quality of maternal nutrition and infant feeding counselling during antenatal care in South Asia
Antenatal care (ANC) provides a platform to counsel pregnant women on maternal nutrition and to prepare the mother to breastfeed. Recent reviews suggest that gaps in the coverage and quality of counselling during pregnancy may partly explain why services do not consistently translate to improved behavioural outcomes in South Asia. This scoping literature review collates evidence on the coverage and quality of counselling on maternal nutrition and…
Complementary feeding in Kongwa, Tanzania
Complementary feeding of 6- to 24-month-old infants and young children with adequate, safe and developmentally appropriate food is essential to child health. Inappropriate complementary foods and feeding practices are linked to the high incidences of undernutrition among infant and young children in most developing countries, including Tanzania. Mycotoxin risk is an additional concern, given the documented presence of aflatoxin and fumonisin in f…
Maternal caregiving capabilities are associated with child linear growth in rural Zimbabwe
Between birth and 2 years, children's well-being depends on the quality of care they receive from caregivers, primarily their mothers. We developed a quantitative survey instrument to assess seven psychosocial characteristics of women that determine their caregiving ability ('maternal capabilities': physical health, mental health, decision-making autonomy, social support, mothering self-efficacy, workload and time stress, and gender norm attitude…
Protocol for the trial to establish a causal linkage between mycotoxin exposure and child stunting
NCT03940547, (April 24, 2019)
Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe
BACKGROUND: Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. METHODS: We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four villag…
An emergency cash transfer program promotes weight gain and reduces acute malnutrition risk among children 6-24 months old during a food crisis in Niger
BACKGROUND: Assessment of the impact of emergency cash transfer programs on child nutritional status has been difficult to achieve due to the considerable logistic and ethical constraints that characterize humanitarian settings. METHODS: We present the findings from a quasi-experimental longitudinal study of a conditional emergency cash transfer program implemented by Concern Worldwide in 2012 during a food crisis in Tahoua, Niger, in which the u…
Trends and predictors of optimal breastfeeding among children 0–23 months, South Asia
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,…
Feasibility of integrating calcium and iron–folate supplementation to prevent preeclampsia and anemia in pregnancy in primary healthcare facilities in Kenya
Calcium (Ca) supplementation to prevent preeclampsia can save maternal and newborn lives, but there are no program models for integration into existing antenatal care platforms. We used a program impact pathway model to guide the design of integrated Ca and iron-folate (IFA) supplementation in Kenya. We provided healthcare providers with job aids (posters and counseling cards), trained them on counseling techniques and supplementation guidelines,…
Using a cultural-ecological framework to explore dietary beliefs and practices during pregnancy and lactation among women in Adivasi communities in the Nilgiris Biosphere Reserve, India
This article explores maternal dietary beliefs and practices gathered through interviews with mothers of infants and young children in Adivasi communities in the Nilgiris Biosphere Reserve, India. Guided by focused ethnographic study methods, interviews were conducted with 33 key informants. We used a cultural-ecological framework to analyze and interpret the texts that were elicited from women about dietary beliefs and eating patterns during pre…
“I Can’t Answer What You’re Asking Me. Let Me Go, Please.”
Cognitive interviewing is a method to develop culturally appropriate survey questions and scale items. We conducted two rounds of cognitive interviews with 24 pregnant women in Ethiopia and Kenya to assess the appropriateness, acceptability, and comprehension of general and micronutrient supplement adherence-specific social support scales. We stopped the first round of cognitive interviews after receiving negative feedback from interviewers and p…
Adherence partners are an acceptable behaviour change strategy to support calcium and iron‐folic acid supplementation among pregnant women in Ethiopia and Kenya
Antenatal calcium and iron-folic acid (IFA) supplementation can reduce maternal mortality and morbidity. Yet, even when pregnant women have a stable supply of supplements, forgetting is often a barrier to adherence. We assessed the acceptability of adherence partners to support calcium and IFA supplementation among pregnant women in Kenya and Ethiopia. Adherence partners are a behaviour change strategy to improve adherence, where pregnant women a…
The association between food insecurity and depressive symptoms severity among pregnant women differs by social support category
Common mental disorders, such as depression and anxiety, affect approximately 16% of pregnant women in low- and middle-income countries. Food insecurity (FI) has been shown to be associated with depressive symptoms. It has also been suggested that the association between FI and depressive symptoms is moderated by social support (SS); however, there is limited evidence of these associations among pregnant women living in low-income and middle-inco…
Stigma as a barrier to treatment for child acute malnutrition in M arsabit C ounty, K enya
Acute malnutrition affects millions of children each year, yet global coverage of life-saving treatment through the community-based management of acute malnutrition (CMAM) is estimated to be below 15%. We investigated the potential role of stigma as a barrier to accessing CMAM. We surveyed caregivers bringing children to rural health facilities in Marsabit County, Kenya, divided into three strata based on the mid-upper arm circumference of the ch…
W orld H ealth O rganization infant and young child feeding indicators and their associations with child anthropometry
As the W orld H ealth O rganization ( WHO ) infant and young child feeding ( IYCF ) indicators are increasingly adopted, a comparison of country‐specific analyses of the indicators' associations with child growth is needed to examine the consistency of these relationships across contexts and to assess the strengths and potential limitations of the indicators. This study aims to determine cross‐country patterns of associations of each of these ind…
Water, sanitation, and hygiene (Wash), environmental enteropathy, nutrition, and early child development
There is scarce research and programmatic evidence on the effect of poor water, sanitation, and hygiene (WASH) conditions of the physical environment on early child cognitive, sensorimotor, and socioemotional development. Furthermore, many common WASH interventions are not specifically designed to protect babies in the first 3 years of life, when gut health and linear growth are established. We review evidence linking WASH, anemia, and child grow…
Breastfeeding practices and child growth outcomes in Haiti
Haiti's national nutrition policy prioritises breastfeeding, but limited data are available to inform strategy. We examined national trends in early initiation of breastfeeding (ErIBF) and exclusive breastfeeding (EBF) over a 10-year period using data from three Haitian Demographic and Health Surveys (1994-1995, 2000 and 2005-2006). We used multivariate regression methods to identify determinants of ErIBF and EBF in the 2005-2006 data set and to …
Complementary feeding practices and child growth outcomes in Haiti
The Haitian National Nutrition Policy identifies the promotion of optimal complementary feeding (CF) practices as a priority action to prevent childhood malnutrition. We analysed data from the nationally representative 2005-2006 Haiti Demographic Health Survey using the World Health Organization 2008 infant and young child feeding indicators to describe feeding practices among children aged 6-23 months and thus inform policy and programme plannin…
Nutrition agenda setting, policy formulation and implementation
Undernutrition is the single largest contributor to the global burden of disease and can be addressed through a number of highly efficacious interventions. Undernutrition generally has not received commensurate attention in policy agendas at global and national levels, however, and implementing these efficacious interventions at a national scale has proven difficult. This paper reports on the findings from studies in Bangladesh, Bolivia, Guatemal…
Complementary feeding messages that target cultural barriers enhance both the use of lipid‐based nutrient supplements and underlying feeding practices to improve infant diets in rural Zimbabwe
Supplementation with lipid-based nutrient supplements (LiNS) is promoted as an approach to prevent child undernutrition and growth faltering. Previous LiNS studies have not tested the effects of improving the underlying diet prior to providing LiNS. Formative research was conducted in rural Zimbabwe to develop feeding messages to improve complementary feeding with and without LiNS. Two rounds of Trials of Improved Practices were conducted with mo…
