Introduction: Obesity is considered one of the most serious public health problems of the 21st century and one of the main causes of morbidity and mortality. The number of children affected by excess body weight is increasing globally. Objective: To estimate the incidence and analyze the effect of initial feeding practices and weight at birth in overweight/obesity at 6/7 years of age. Methods: We conducted a retrospective cohort study, involving 473 children registered in the first year of elementary school to public and private schools, and their families, residing in the municipality of Palhoça/SC. Demographic data and for the initial feeding practices were obtained through interviews with the mothers of school children in households. The birth weight and gestational age were obtained by querying the health portfolio. Anthropometric data of were collected in visits to schools. Were calculated the body mass indexes subsequently classified according to z scores curves proposed by the World Health Organization. Descriptive analyses were undertaken of the variables of the study. Bivariate analyses were performed to test the homogeneity of proportions, through the Chi-square. Multivariate analysis was carried out through the Cox Regression to estimate the effects of any of confusion variables. Risk Ratios (RR) and their respective confidence intervals were estimated. Results: we observed an incidence of 33.2% (IC 95% 28.9; 37.5) of overweight/obesity in the population studied. Non-breastfed children presented a risk of 1.66 (95% CI 1.06; 2.61) (p = 0.027) to develop overweight/obesity at 6/7 years of age, regardless of the other variables studied. Socio-demographic characteristics, relating to birth weight and feeding until two years of age were not statistically associated. Conclusion: the incidence of Overweight/obesity was 33.2% among schoolchildren of the age group studied in the municipality of Palhoça. Among these, children are not breastfed presented a statistically greater risk of developing overweight/obesity at 6/7 years when compared with those who had breastfeeding.
