title: Risk factors for diarrheal disease incidence in early childhood: a community cohort study from Guinea-Bissau.
abstract: To determine risk factors for diarrhea, the authors followed an open cohort of 1,314 children from Guinea-Bissau by weekly diarrhea recall interviews between April 1987 and March 1990. Data on feeding practices and measles infection were available for all children and, for 531 children, comprehensive data on explanatory variables were recorded. Of 57 variables, seven were independently associated with an increased incidence of diarrhea. These were a recent (in the past 14 days) diarrheal episode, male sex, being weaned from breast milk, not being looked after by the mother, head of the household being < 30 years old, eating cold leftovers, and drinking water from an unprotected public water supply. In breastfed children, only three variables were associated with diarrhea, including prior diarrhea, male sex, and not being looked after by the mother. Among weaned children, six variables delineated increased rates of diarrhea, including unprotected public water supply, eating of cold leftovers, and lack of maternal education. Major determinants of persistent diarrhea included weaning, lack of maternal education, and having pigs in the home. It is concluded that, in addition to the promotion of breastfeeding, important interventions against diarrhea include improvements in water supply, hygiene, and food handling. However, because of effect modification by breastfeeding, the largest effects of these interventions will probably be among weaned children.
