OBJECTIVES: to study breastfeeding during the first year of life and the kind of complementary food provided at one year of life to children of adolescent mothers. To compare these data with breastfeeding and complementary food received by children of adult mothers. METHOD: a dual cohort was performed. Children were selected from the files of CAISM/UNICAMP and assessed when they were one year old. This study consisted of 122 children born from adolescent mothers and 123 children born from adult mothers - full-term births, birthweight was 2,500 g or higher. When the children were one year old, the mothers were interviewed at home or at CIPED/UNICAMP. The results were compared using the chi-square test and the Fisher's test; a= 5%; the Kaplan-Meier method was used to analyze the duration of breastfeeding and the Wilcoxon test (Breslow) to compare the exclusive, predominant, full and total breastfeeding curves. RESULTS: 94.3% of children of adolescent mothers and 95.9% of children of adult mothers left the maternity hospital being breastfed (p = 0,544). The median exclusive breastfeeding duration for both groups was 90 days. After completing one year, 35.3% and 28.5% of children of adolescent and adult mothers, respectively, continued breastfeeding (p = 0.254): only breastfeeding 11.5% x 8.9% and mixed feeding 23.8% x 19.5% (p = 0.519). Meat intake by children of adolescent mothers was lower than that of children of adult mothers (13.9% x 26.0%; Fisher's test: p = 0.031). With regard to egg intake, 11.5% x 19.5% of children of adolescent mothers and adult mothers did not eat egg but the results suggested that the egg intake of children of adolescent mothers was higher (p = 0.082). CONCLUSIONS: duration and pattern of breastfeeding were similar between children of adolescent mothers and of adult mothers. The complementary nutrition was similar, except for a lower intake of meat and a higher intake of eggs among the children of adolescent mothers.
