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.
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<or=0.05) lower CRF scores and higher BW (P<or=0.05) than did the NOW pears. Overall, 92.9% of OV/OB girls had one or two parents with OV/OB (P<or=0.05). Boys with low CRF (odds ratio (OR): 3.75; P<or=0.05) and high BW (OR: 1.65; P<or=0.05) were more likely to be classified as OV/OB compared with NOW. Girls with low CRF (OR: 2.66; P<or=0.05), high BW (OR: 2.09; P<or=0.05) and at least one parent (OR: 2.28; P<or=0.05) or two parents with OV/OB (OR: 4.39; P<or=0.05, respectively) were classified as OV/OB.
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.
背景/目的：本研究的目的如下：（1）分析心肺适能（CRF）、父母的体重指数（BMI）和出生体重（BW）在非超重（NOW）和超重/肥胖（OV/OB）青少年之间的差异；（2）探讨这些变量与青少年后代超重/肥胖风险的关系。
受试者/方法：本研究纳入了 788 名 12 至 18 岁的青少年（477 名女孩和 311 名男孩）。CRF 通过最大多阶段 20 米穿梭跑测试来预测，测试程序按照 FITNESSGRAM 中的描述进行。根据国际肥胖工作组的标准，将儿童 BMI 进行分类。青少年的 BW 根据每个孩子出生时的儿科记录进行评估。父母的超重/肥胖状态根据世界卫生组织的标准进行定义和分类。社会经济地位由父母的教育程度定义。
OV/OB 的患病率分别为 21.4%和 5.3%，性别间无差异。OV/OB 青少年（女孩和男孩）的 CRF 评分显著降低（P<0.05），BW 显著升高（P<0.05）。总体而言，92.9%的 OV/OB 女孩有一个或两个超重/肥胖的父母（P<0.05）。与 NOW 相比，低 CRF（比值比（OR）：3.75；P<0.05）和高 BW（OR：1.65；P<0.05）的男孩更有可能被归类为 OV/OB。低 CRF（OR：2.66；P<0.05）、高 BW（OR：2.09；P<0.05）、至少有一位父母超重/肥胖（OR：2.28；P<0.05）或两位父母超重/肥胖（OR：4.39；P<0.05）的女孩更有可能被归类为 OV/OB。
本研究结果强调了青少年肥胖与家庭肥胖的相关性，在女孩中更为明显。此外，我们的数据表明，低 CRF 和高 BW 是青少年超重/肥胖的强有力预测指标。
