The object of this study is to determine the prevalence of potential delays in neuropsychomotor development and their possible association with, on one hand, environmental and biological factors, and maternal competence on the other, in a sample of children up to six years old living in Canoas, in Rio Grande do Sul state. A questionnaire was submitted to mothers including questions on social, economic and reproduction factors; child's conditions at birth; child's pathologies; family structure; child care and elements on maternal competence. The potential for neuropsychomotor development delay was assessed by the Denver II Test. Forty clusters were visited in Canoas, a city in Rio Grande do Sul state, in accordance with the cluster probabilistic sampling process. From 197 children assessed by this analytical cross-section study, there was a 27% (n=53) prevalence of potential delay in neuropsychomotor development. The multivariate analysis showed that factors associated with potential development delays were: low income (or = 9,3); mothers with less than 18-month intervals between pregnancies (or=3,9) ; and lack of support from child's father (or=7,0). These results support the importance of implementing income generating programs, health education, and family planning in order to prevent child development delays.
