Resumen

Introduction: Excessive gestational weight gain predisposes new mothers to postpartum overweight status or obesity, which is a worldwide public health problem. Objective: To analyze the pattern of gestational weight and body fat gain in adolescents and adults to identify the group with greater weight and body fat gain. Materials and methods: A cohort of 64 adolescents at most 18 years of age and 48 adults was evaluated for weight and body fat percentage at gestational weeks (gw) 20, 24, 28, 32, 36, and 38, with informed consent. Results: In adolescents, weight and pre-gestational body mass index (BMI) were lower (p < 0.001) and gain of gestational body fat was greater than in adults (5.31 vs. 4.12 kg; p < 0.001). Pre-gestational BMI â = 0.459, SEM = 0.089, p = 0.001) and age (â = 1.400, SEM = 0.735, p = 0.060) also contributed to variability in body fat percentage. Underweight adolescents and those with overweight or obesity (BMI > the 85^th percentile) gained more weight than those who were classified as normal weight (18.0, 15.5 and 12.0 kg, respectively; p = 0.018). In addition, 54.7% of adolescents and 64.6% of adults gained more weight than is recommended for their pre-gestational BMI. Conclusions: Pre-gestational BMI and age contribute to body fat changes during gestation. More than half of the participants in this study exceeded the recommended gestational weight gain. Overweight adolescents or those with excessive weight gain may have a higher risk of retaining weight postpartum than adults in the same situation.
