Introduction The study of the effects of breastfeeding over growth or in protection against infant obesity still have many controversy or inconclusive results. In Brazil there are feel data and analysis about this subject. Objective To analyze the breastfeeding influence on nutritional status of children under 3 years old of São Paulo City. Methods The longitudinal sub-sample with 760 children aged less than 36 months of a population-based study called The Health of São Paulo Children II was used. The outcome variables were the anthropometric indexes height-for-age index (ZAI), BMI-for-age index (ZBI) and triceps-skinfold-thickness-for-age index (ZDI), expressed in standard deviations (Z scores) of the World Health Organization reference standard (2006). The association between predominant breastfeeding (PBF) and the nutritional indexes was adjusted for: family income, years of maternal education, birth weight, birth order, maternal age and maternal work status. The fixed and random effects of the determinants of child growth, in 3 home visits, were estimated using panel analysis. Results The duration of PBF was negatively associated with all the anthropometric indexes. The mean effect of PBF on the indexes was of -0,068 Z on ZAI, -0,044 Z on ZBI and -0,065 Z on ZDI (p<0,05, all cases). The means of each index had decreasing dose-response effects according to the raise of the PBF duration. The PBF effect over children nutritional status was modified by controlling its interaction with maternal education: children of women with 8 or more years of study had mean height 0,075 Z higher than children of women with 3 or less years of study (p<0,05); for BMI, this interaction was not statistically significant. Conclusion Predominant breastfeeding was negatively associated to the children nutritional indexes, with a protection effect against high mean of BMI and body fat in children aged less then 3 years old in São Paulo City.
