However, most studies have neglected important dynamic features of the longitudinal design and hierarchical interrelationships among the potential risk factors. Methods: We conducted a longitudinal study of 902 children, age 0 to 36 months at baseline, in a large urban center in northeastern Brazil. Diarrhea data were collected by following children from October 2000 until January 2002 with biweekly home visits. We used a dynamic time-to-event analysis to account for several longitudinal features. We applied an effect-decomposition strategy to quantify direct and indirect effects of risk factors grouped in different blocks. Results: Child's age and an autoregressive effect of past diarrhea episodes explained some of the decline of diarrhea incidence observed throughout the study (from more than 14 episodes to 2 episodes per child-year), a phenomenon already observed but not explained in other longitudinal diarrhea studies. We identified the following major diarrhea determinants: low socioeconomic status, poor sanitation conditions, presence of intestinal parasites, and absence of prenatal examination. The effect of socioeconomic status was mediated mostly by living and sanitation conditions. Conclusion: Our study shows important advantages of applying a dynamic analysis approach to longitudinal observational studies of diarrhea or other acute diseases and highlights the complex interrelationships of diarrhea determinants. Our results confirm the importance of sanitation as a major determinant of child health in urban settings of developing countries.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-07-03T11:35:16Z No. of bitstreams: 1 00001648-200611000-00011.pdf: 730780 bytes, checksum: b31a5ef84cff46174207a9166d2d806c (MD5)Made available in DSpace on 2013-07-03T11:35:17Z (GMT).
