Summary
Postmenopausal women spend most of their day sedentary. Identifying distinct physical activity and sedentary behavior patterns can inform public health guidelines for this population.
Area of Science:
- Gerontology
- Public Health
- Kinesiology
Background:
- Physical activity and sedentary behavior patterns in postmenopausal women are not well understood.
- Characterizing these behaviors is crucial for targeted health interventions.
Purpose of the Study:
- To describe the patterns of physical activity and sedentary behavior in postmenopausal women using accelerometer data.
- To identify distinct profiles of habitual physical activity and sedentary behavior.
Main Methods:
- A cross-sectional study involving 6126 women aged 63-97 years.
- Participants wore an accelerometer for one week to assess physical activity and sedentary behavior.
- Latent class analysis was employed to classify women into distinct behavioral patterns.
Main Results:
- On average, women spent 62.3% of their day in sedentary behavior.
- Light physical activity comprised 21.1% and 11.0% of the day, while moderate-to-vigorous activity was 5.6%.
- Five classes emerged for single behaviors, and six classes for a multi-component model integrating all behaviors.
Conclusions:
- Unique profiles of physical activity and sedentary behavior were identified in postmenopausal women.
- These findings offer new insights into habitual patterns for this demographic.
- A multi-component approach can refine public health guidelines for physical activity and sedentary behavior.
