The present study investigates into some socio-economic, demographic, and nutritional features that can predispose Bangladeshi children to malnutrition and Shigella flexneri infection. Significant prognostic indicators associated with malnutrition were mother's illiteracy (unadjusted odds ratio, OR = 2.580; 95% confidence interval, CI = 1.134-5.867 and adjusted odds ratio, ORa, 3.814; 95% CI = 1.124-12.943), low birth weight (OR = 3.143; 95% CI = 1.2-8.232 and ORa = 2.404; 95% CI = 0.870-6.644) and poor socioeconomic status (OR = 2.549; 95% CI = 1.382-4.701 and ORa = 1.808; 95% CI = 0.852-3.838). Age was the strongest predictor for the acquisition of S. flexneri infection in the studied population (OR = 5.472; 95% CI = 2.583-11.592 and ORa = 5.808; 95% CI = 2.420-13.942). The severity of malnutrition was significantly (P = 0.033) related to seroprevalence of S. flexneri infection. To reduce malnutrition emphasis should be given on controlling the incidence of low birth weight, improving the literacy status especially of mothers and narrowing the gap between different socio-economic levels. Malnourished children should be examined for severity and direct intervention therapy should be given when necessary.
