The main aim of this study was to investigate the influence of the route of delivery, birth weight and overweight onset on overweight severity in a sample of overweight adolescents followed at a Pediatric Obesity Clinic.

Methods. Clinical data from 412 adolescents with overweight (BMI ≥ p85), aged 10-18 were retrospectively collected and analyzed.

Results. Adolescents born by cesarean section (CS) showed a lower age of overweight onset, compared to other methods of delivery (d= 0.33, p= .009). Birth weight was positively associated with BMI z-score (r=.164, p= 002) and waist circumference (WC) (r=.191, p=.001). The overweight onset was negatively associated with BMI z-score (r= -.277, p <.001), WC (r= -.270, p <.001) and body fat mass (r= -.199, p=.001). Overweight duration was the best predictor of BMI z-score, explaining in 75% its variation (F=1,317)=26.94, p <.001), which increased to 99% when birth weight was included in the model (F(2,316)=18.47, p <.001).

Conclusions. This study suggests that lifestyle may interrupt the burden of CS on BMI z-score throughout growth. Moreover, increased birth weight may anticipate overweight onset, and consequently overweight duration in the presence of inadequate lifestyle behaviors.
