Associations between Physical Activity, Sedentary Time, and Locomotive Syndrome Differ by Age and Sex: A...

Area of Science:

• Gerontology
• Public Health
• Exercise Science

Background:

• Locomotive syndrome (LS) is a significant health concern, particularly in aging populations.
• Physical activity is recognized as a key factor in managing LS, but the impact of activity intensity remains unclear.

Purpose of the Study:

• To investigate the relationship between different intensities of physical activity (vigorous, moderate, light) and sedentary time with locomotive syndrome (LS).
• To examine these associations across different age and sex demographics.

Main Methods:

• Cross-sectional analysis of 2890 Japanese community residents.
• LS assessed via stand-up test, two-step test, and Geriatric Locomotive Function Scale.
• Physical activity and sedentary time evaluated using self-administered questionnaires.
• Logistic regression analysis stratified by age (<65 and ≥65 years) and sex.

Main Results:

• Vigorous physical activity was associated with lower LS odds in men aged ≥65 and women aged <65.
• Moderate physical activity was linked to lower LS odds in women aged <65.
• No significant association between light physical activity and LS was found.
• Sedentary time was associated with LS in women aged <65.

Conclusions:

• Physical activity and sedentary time exhibit age- and sex-dependent associations with locomotive syndrome.
• Promoting high-intensity physical activity is crucial for preventing and managing LS.
• Tailored physical activity interventions based on age and sex may be beneficial.
