中高年労働者における余暇身体活動と歩数の組み合わせと高血圧有病率の関係

The purpose of this study was to evaluate the relationship between workers’ overall physical activity level, combining leisure-time physical activity and daily step counts, and the prevalence of hypertension, through a large-scale survey of middle-aged and older workers across Japan.

Physical activity, which could potentially prevent hypertension, is in short supply and is a public health problem that should be addressed on a global scale. However, limited research has investigated the association between overall physical activity, which combines leisure-time physical activity and daily step count, and hypertension prevalence. The study participants were middle-aged and older workers at workplaces throughout Japan. The study participants were 5,812 individuals who agreed to use anonymized data and responded to a comprehensive version of the Health Advice Service Check Sheet.

When comparing the group with low leisure-time physical activity and low daily step counts, the multivariable-adjusted odds ratio (95% CI) for the high leisure-time physical activity and low daily step count group was 0.77 (0.61–0.98), the low leisure-time physical activity and high daily step count group was 0.95 (0.78–1.16), and the high leisure-time physical activity and high daily step count group was 0.72 (0.57–0.90). When leisure-time physical activity and daily step counts were analyzed together, the lowest prevalence of hypertension was observed in those with high leisure-time physical activity and high daily step counts. These results suggest the importance of increasing physical activity to prevent hypertension among Japanese workers.
