导论.本研究的目的是检查代谢健康肥胖（MHO）和代谢不健康肥胖（MUO）青少年和成人的身体活动（PA）和屏幕时间（ST）水平。方法.汇总了2003-2005年周期的肥胖青少年（12-18岁，BMI z评分≥第95百分位数）和成人（19-85岁，BMI ≥ 30 kg/m2）的NHANES数据。代谢表型分类为MHO（0或1个心脏代谢风险因素;甘油三酯、HDL-C、血压或葡萄糖）或MUO（≥2个心脏代谢风险因素）。Logistic回归模型估计了表型与PA/ST之间的相关性，校正了年龄、性别、BMI、种族/民族、绝经状态和NHANES周期。结果在青少年中，PA与MHO无关。相比之下，19-44岁的MHO成年人参与主动交通的可能性高出85%，参与轻度日常活动的可能性是坐着的2.7倍。对于每天每分钟，45-85岁的成年人有36%的可能性具有较高水平的中度PA的MHO表型。ST与青少年或成人的代谢表型无关。结论目前的研究提供的证据表明，PA，而不是ST，MHO和MUO之间的成人，但不是在青少年不同。需要进一步的研究来证实结果。
Introduction. The purpose of this study was to examine levels of physical activity (PA) and screen time (ST) in metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO) adolescents and adults. Methods. NHANES data from obese adolescents (12–18 years, BMI z-score ≥ 95th percentile) and adults (19–85 years, BMI ≥ 30 kg/m2) were pooled from 2003–2005 cycles. Metabolic phenotypes were categorized as MHO (0 or 1 cardiometabolic risk factor; triglycerides, HDL-C, blood pressure, or glucose) or MUO (≥2 cardiometabolic risk factors). Logistic regression models estimated associations between phenotype and PA/ST adjusted for age, gender, BMI, race/ethnicity, menopausal status, and NHANES cycle. Results. Among adolescents, PA was not associated with MHO. In contrast, MHO adults 19–44 years were 85% more likely to engage in active transportation and 2.7 times more likely to be involved in light intensity usual daily activity versus sitting. For each minute per day, adults 45–85 years were 36% more likely to have the MHO phenotype with higher levels of moderate PA. ST was not associated with metabolic phenotypes in adolescents or adults. Conclusion. The current study provides evidence that PA, but not ST, differs between MHO and MUO in adults, but not in adolescents. Future studies are needed to confirm results.
