Determinants of delayed initiation of breastfeeding: a community and hospital study from Guinea-Bissau.

A prospective study on the timing of breastfeeding start in Bissau was undertaken in a periurban community (n = 734), and at the Central Hospital (n = 414). Only single, full-term, healthy children born by the vaginal route were included, the purpose being to characterize mothers who delay breastfeeding start for reasons not related to disease. Multivariate failure-time analysis (Cox' regression) was used to relate the child's age at breastfeeding start to a set of independent variables. In the community, those tending to delay breastfeeding start were mothers from the largest ethnic group in the country, mothers who had given birth at times other than the evening hours (6-12 pm) and mothers who had not attended antenatal clinics. At the hospital, delayed initiation was found among young mothers and mothers from one sparsely represented ethnic group. The most important determinant of delayed breastfeeding start was negative cultural ideas about colostrum.
