It is still not known whether overweight men have different patterns and socio-demographic correlates of self-reported physical activity (PA) compared with normal-weight men. Thus, this study examined the perceived PA patterns and associated socio-demographic factors among normal-weight and overweight Japanese men.
Data were analyzed for 1,420 men (aged 44.4 ± 8.3 years) who responded to an Internet-based cross-sectional survey relating to socio-demographic variables, BMI status, and a short version of the International Physical Activity Questionnaire. Mann-Whitney, chi-square, and binary logistic regression analyses were employed.
Normal-weight men were significantly more likely to attain 150 minutes per week of moderate-to-vigorous PA than overweight men (26.6% vs. 21.3%; p=0.035), whereas there were no significant proportional differences in total PA and walking between the two BMI subgroups. With PA, a significant interaction was observed between BMI status and household income (p=0.004 for total PA; p=0.02 for walking). In the subgroup analyses, having a lower household income (odds ratio, 0.63; 95% confidence interval, 0.41-0.96) was negatively associated with attaining 150 minutes of walking per week among normal-weight men. No significant associations between household income and attaining 150 minutes per week of total PA and walking were found among overweight men.
The results revealed that patterns and socio-demographic correlates of self-reported PA in overweight men are different from those in normal-weight men. This finding suggests the necessity of developing specific strategies for PA intervention among overweight men. Socio-demographic correlates of PA may be more important for normal-weight than overweight men.
目前尚不清楚超重男性与正常体重男性相比，其自我报告的体力活动（PA）模式是否存在差异，以及与社会人口学因素的相关性是否存在差异。因此，本研究旨在探讨日本正常体重和超重男性的感知 PA 模式及其相关社会人口学因素。
本研究对 1420 名男性（年龄 44.4±8.3 岁）进行了分析，这些男性通过互联网完成了一项关于社会人口学变量、BMI 状态和国际体力活动问卷短版的横断面调查。采用 Mann-Whitney、卡方和二元逻辑回归分析。
与超重男性相比（26.6%比 21.3%；p=0.035），正常体重男性更有可能达到每周 150 分钟的中等至剧烈强度的 PA，而两组之间的总 PA 和步行 PA 没有显著的比例差异。在 PA 方面，BMI 状态和家庭收入之间存在显著的交互作用（总 PA 为 p=0.004；步行 PA 为 p=0.02）。在亚组分析中，家庭收入较低（比值比，0.63；95%置信区间，0.41-0.96）与正常体重男性每周达到 150 分钟的步行量呈负相关。在超重男性中，家庭收入与达到每周 150 分钟的总 PA 和步行 PA 之间没有显著关联。
研究结果表明，超重男性自我报告的 PA 模式和社会人口学相关性与正常体重男性不同。这一发现表明，需要为超重男性制定特定的 PA 干预策略。PA 的社会人口学相关性对正常体重男性可能比对超重男性更为重要。
