Unsafe Drinking Water Is Associated with Environmental Enteric Dysfunction and Poor Growth Outcomes in Young Children in Rural Southwestern Uganda

Publication Type

Environmental enteric dysfunction (EED), a subclinical disorder of the small intestine, and poor growth are associated with living in poor water, sanitation, and hygiene (WASH) conditions, but specific risk factors remain unclear. Nested within a birth cohort study, this study investigates relationships among water quality, EED, and growth in 385 children living in southwestern Uganda. Water quality was assessed using a portable water quality test when children were 6 months, and safe water was defined as lacking Escherichia coli contamination.

Association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes in Uganda

Publication Type

Aflatoxins are toxic metabolites of Aspergillus molds and are widespread in the food supply, particularly in low‐ and middle‐income countries (LMICs). Both in utero and infant exposure to aflatoxin B1 (AFB1) have been linked to poor child growth and development. The objective of this prospective cohort study was to investigate the association between maternal aflatoxin exposure during pregnancy and adverse birth outcomes, primarily lower birth weight, in a sample of 220 mother‐infant pairs in Mukono district, Uganda.

Risk factors associated with Environmental Enteric Dysfunction (EED) in rural southwestern Uganda

Publication Type

This poster draws links between water quality sanitation, among other factors and EED with data from a cross-sectional, observational birth cohort study in southwestern Uganda. Presented at Friedman Fellows in 2017.

Infant Nutritional Status and Markers of Environmental Enteric Dysfunction are Associated with Midchildhood Anthropometry and Blood Pressure in Tanzania

Publication Type

Children who participated in 2 randomized trials micronutrient supplements in infancy were followed up in midchildhood (4.6-9.8 years of age). Anthropometry was measured at age 6 and 52 weeks in both trials, and blood samples were available from children at 6 weeks and 6 months from 1 trial. Linear regression was used for height-for-age z-score, body mass index-for-age z-score, and weight for age z-score, and blood pressure analyses; log-binomial models were used to estimate risk of overweight, obesity, and stunting in midchildhood.
