尽管体力活动不足(PA)和高屏幕时间(ST)都是肥胖的独立危险因素，但充足/不足的PA和高/低ST的组合如何会增加日本成年人的肥胖风险尚不清楚。这项研究调查了PA和ST与日本成年人超重的联合关系。一项基于互联网的调查收集了2832名成年人的身高、体重、自我报告的在PA和ST度过的时间以及社会人口统计变量的数据。根据公共PA指南和ST的中位数，受访者被分为PA充足/低ST段、PA充足/高ST段、PA不足/低ST段、PA不足/高ST段。Logistic回归分析超重(体重指数，≥25 kg/m2)与PA、ST的比值比(OR)。与PA/低ST充分类别相比，PA不足/ST高类别的参与者在调整社会人口学变量后更有可能超重(OR，1.48；95%可信区间[95%CI]，1.14，1.93)。在PA/高ST类型不足的人群中，男性超重(包括肥胖)的OR也显著更高，但在女性中没有发现显著的关联。PA不足和ST段延长都会导致日本成年人超重和肥胖。在日本，应对肥胖的公共卫生倡议需要同时考虑促进PA和减少ST，特别是在男性中。
Although both insufficient physical activity (PA) and high screen time (ST) are independent risk factors for obesity, how the combination of sufficient/insufficient PA and high/low ST could increase obesity risk among the adult population of Japan is not known. This study examined joint associations of PA and ST with overweight among Japanese adults. An Internet-based survey collected data on height, weight, self-reported time spent in PA and ST, and sociodemographic variables from 2832 adults. Respondents were categorized into sufficient PA/low ST, sufficient PA/high ST, insufficient PA/low ST, or insufficient PA/high ST categories as per public PA guidelines and the median of ST. Logistic regression analysis examined the odds ratios (OR) of being overweight (body mass index, ≥ 25 kg/m2) according to the categories of PA and ST. In comparison with the sufficient PA/low ST category, participants in the insufficient PA/high ST category were significantly more likely overweight (OR, 1.48; 95% confidence interval [95%CI), 1.14, 1.93) after adjusting for sociodemographic variables. A significantly higher OR for overweight (including obesity) among insufficient PA/high ST category was also observed in men, but no significant association was found in women. Both insufficient PA and prolonged ST contribute to overweight and obesity among Japanese adults. Public health initiatives addressing obesity in Japan need to consider both promoting PA and reducing ST, especially in men.
