Summary
Regular physical activity significantly lowers hip fracture risk in postmenopausal women. This protective effect is amplified in women who have lost weight since age 18.
Area of Science:
- Gerontology
- Epidemiology
- Public Health
Background:
- Growing evidence suggests physical activity is a key factor in preventing hip fractures.
- Hip fractures pose a significant health risk, particularly for postmenopausal women.
Purpose of the Study:
- To investigate the association between hip fracture risk and recreational physical activity across different life stages.
- To examine the influence of changes in physical activity and body weight on hip fracture risk.
Main Methods:
- Population-based case-control study involving 1327 postmenopausal women with hip fractures and 3262 controls.
- Assessed leisure physical activity at various ages (pre-18, 18-30, recent) via questionnaire.
- Evaluated occupational physical activity using job title classification linked to census data.
Main Results:
- Recent leisure physical activity demonstrated a protective effect against hip fracture.
- Increased hours of weekly physical activity correlated with reduced hip fracture odds ratios.
- The protective effect was more pronounced in women who experienced weight loss after age 18.
Conclusions:
- Recent physical activity is a significant protective factor for preventing hip fractures.
- Weight loss after age 18 enhances the protective benefits of physical activity against hip fracture.
