Four hundred ninety-fi ve children between 0 and 17 years old provided information about their dietary intake in 966 24-hour dietary recall.Their nutritional status was established based on anthropometry using the growth patterns of WHO.Energy and macronutrients in 27 categories of dietary intake of snacks was determined.The aim was to establish the relationship between excess weight, snacking and consumption of energy derived from them.Based on models of linear regression and binomial where excess weight was the dependent variable and the explanatory power consumption, prevalence ratios (RP) and adjusted differences were calculated.Although energy from snack consumption increases with socioeconomic status, 751 (717, 786) kcal more in quintile 5 versus quintile 1, p <0.0001, the risk of excess in those taking snack is not statistically signifi cant compared to those who did not consume, RP 1. 05 (0.40 to 2.76).In conclusion, we established that consumption of snacks is not a determinant of overweight in Colombian children and that the main determinant of overweight and consumption of snacks is urban planning, social development, economic and level of wealth.
