Abstract | OBJECTIVE: to evaluate the relationship between body composition of preschool children suffering from excess weight and birth weight (BW). METHODS: probabilistic sample, by conglomerates, with 17 daycare centers (of a total of 59) composing a final sample of 479 children. We used Z-score of Body Mass Index (zBMI) ≥ +1 and ≥ +2, respectively, to identify preschool children with risk of overweight and excess weight ( overweight or obesity). The arm muscle area (AMA) and the arm fat area (AFA) were estimated from measurements of arm circumference, triceps skin fold thickness. RESULTS: the prevalence of risk of overweight was 22.9% (n=110) and excess weight was 9.3% (n=44). The risk of overweight and excess weight in children did not show correlation between BW and AFA, but it did with adjusted arm muscle area ( AMAa) (rp= 0.21; p= 0.0107). The analysis of the group with excess weight alone also showed a positive correlation between BW and AMAa (rp= 0.42; p= 0.0047). CONCLUSION: among overweight children, lower BW is associated with a lower arm muscle area in early preschool age, regardless of the fat arm area presented by them.
