Background/Objectives: The aims of this study were as follows: (1) to analyze differences in cardiorespiratory fitness (CRF), parents' body mass index (BMI) and birth weight (BW) between non-overweight (NOW) and overweight/obese (OV/OB) adolescents, and (2) to investigate the association of those variables with the risk of their biological offspring being OV/OB. Subjects/Methods: This study comprised 788 adolescents (477 girls and 311 boys), aged between 12 and 18 years. CRF was predicted by maximal multistage 20-m shuttle-run test according to the procedures described in FITNESSGRAM. Children's BMI was classified according to the International Obesity Task Force. Adolescents' BW was assessed from each child's pediatric record at birth. Parents' OV/OB status was defined and classified according to the World Health Organization. Socioeconomic status was defined by parental education. Results: The prevalence OV/OB was 21.4 and 5.3%, respectively, and there were no gender differences. The OV/OB adolescents (girls and boys) had significantly (P [less than or equal to] 0.05) lower CRF scores and higher BW (P [less than or equal to] 0.05) than did the NOW pears. Overall, 92.9% of OV/OB girls had one or two parents with OV/OB (P [less than or equal to] 0.05). Boys with low CRF (odds ratio (OR): 3.75; P [less than or equal to] 0.05) and high BW (OR: 1.65; P [less than or equal to] 0.05) were more likely to be classified as OV/OB compared with NOW. Girls with low CRF (OR: 2.66; P [less than or equal to] 0.05), high BW (OR: 2.09; P [less than or equal to] 0.05) and at least one parent (OR: 2.28; P [less than or equal to] 0.05) or two parents with OV/OB (OR: 4.39; P [less than or equal to] 0.05, respectively) were classified as OV/OB. Conclusions: Results from this study highlight the association between the family adolescents' obesity, in girls. Furthermore, our data suggested that low CRF and high BW were strong predictors of OV/OB in adolescence.
