Education and micronutrient deficiencies: an ecological study exploring interactions between women's schooling and children's micronutrient status.

Publication Type

Formal education can be a nutrition-sensitive intervention that supports the scale-up and impact of nutrition-specific actions. Maternal education has long been linked to child survival, growth, and development while adult earnings and nutrition are tied to years in school as a child. However, less is known about the relationship between maternal education and the micronutrient status of children, women and the general population.

Misreporting Month of Birth: Implications for Nutrition Research

Publication Type

Height-for-age z-scores (HAZs) and stunting status (HAZ<−2) are widely used to measure child nutrition and population health. However, accurate measurement of age is nontrivial in populations with low levels of literacy and numeracy, limited use of formal birth records, and weak cultural norms surrounding birthdays and calendar use. In this paper we use Demographic and Health Surveys data from 62 countries over the period 1990–2014 to describe two statistical artifacts indicative of misreporting of age.

Household food production is positively associated with dietary diversity and intake of nutrient-dense foods for older preschool children in poorer families: Results from a nationally-representative survey in Nepal

Publication Type

Nutrition-sensitive interventions supporting enhanced household food production have potential to improve child dietary quality. However, heterogeneity in market access may cause systematic differences in program effectiveness depending on household wealth and child age. Identifying these effect modifiers can help development agencies specify and target their interventions.

Behavior Change for Early Childhood Nutrition: Effectiveness of Health Worker Training Depends on Maternal Information in a Randomized Control Trial

Publication Type

We carry out a randomized control trial to test for interaction effects between training state-employed caregivers and providing mothers information to improve nutrition of preschool children aged 2-6 in rural India. Salaried caregivers are supposed to provide a mid-day meal and also advise mothers on health and nutrition for their child. Our one-day caregiver training covered basic health and nutrition facts with advice on how to communicate with mothers for behavior change at home.

Nutrient composition of premixed and packaged complementary foods for sale in low- and middle-income countries: Lack of standards threatens infant growth

Publication Type

Premixed flours for infant porridge are increasingly produced and sold in developing countries to complement continued breastfeeding. Such complementary food (CF) products have known efficacy against malnutrition in children from 6 to 24 months of age, but ingredient ratios and production processes may vary. This study provides the first systematic measurement of their actual nutrient composition. We purchased samples of 108 premixed CF products in 22 low- and middle-income countries, and commissioned blind laboratory measurement of each product's macronutrients and micronutrients.

The Nutrition Transition and Agricultural Transformation: a Preston curve approach

The nutrition transition in diets and health is closely tied to other aspects of economic development, including agricultural transformation and urbanization as well as demographic change and epidemiological transition from infectious to noncommunicable disease. Over time, dietary patterns typically shift from widespread inadequacy of many foods and nutrients, especially for children and mothers, into surplus energy intake and rising obesity with continued inadequacy of healthier foods. Diet-related diseases remain the largest single cause of premature death and disability in all regions.
