Etiology, Risk factors and Interactions of Enteric Infections and Malnutrition and the Consequences of Child Health and Development (MAL-ED) Cohort Study
In the MAL-ED cohort study, the researchers assessed child development in a harmonious manner across 8 sites in 8 low- and middle-income countries. From birth to 24 months, development and language acquisition were assessed. They also measured infant temperament, the child's environment, maternal psychological adjustment and maternal reasoning abilities. The study aims to identify the periods during the first 2 years of life when specific infections are associated with the greatest effect on growth and development. Factors evaluated for their effects include enteric and other infections, micronutrient levels, dietary intake, socioeconomic status, maternal depressive symptoms, and the home environment. Data are also being collected in anthropometry, gut function, microbiology, nutrition, vaccine response, and cognitive development. Data collection took place in 8 field sites: Dhaka, Bangladesh; Fortaleza, Brazil; Vellore, India; Bhaktapur, Nepal; Loreto, Peru; Naushero Feroze, Pakistan; Venda, South Africa; and Haydom, Tanzania. Information is collected at individual, household and community level.
