Outline
Postmenopausal osteoporosis (PMOP) is highly prevalent among elderly women. Current research on the effects of physical activity types and region-specific dietary patterns is insufficient. Large-scale cross-sectional studies are needed to analyze these multidimensional factors.
To investigate the impact of physical activity and dietary patterns on PMOP and their interaction effects.
In May 2022, a baseline survey was conducted among postmenopausal women aged 60 and above in Hongguang Town, Pidu District, Chengdu. Physical activity levels were assessed using the International Physical Activity Questionnaire (IPAQ), and dietary information was collected via a food frequency questionnaire. Dietary patterns were identified using factor analysis, and bone density was measured by dual-energy X-ray absorptiometry (DXA). Multivariate logistic regression was used to analyze the independent and interaction effects.
A total of 1 136 postmenopausal women (mean age 67.2±5.1 years) were included, with a PMOP prevalence of 32.8%. After adjustment, recreational physical activity was negatively associated with PMOP (OR=0.64, 95% CI: 0.45-0.92). The Sichuan-style high-sodium red meat pattern and freshwater fish–poultry pattern showed no significant association after adjustment. Interaction analysis revealed that walking had a significant synergistic effect with dietary patterns (Pinteraction=0.008), while other physical activities did not.
Physical activity and dietary patterns have independent and synergistic effects on PMOP. This study provides region-specific clues for exercise and dietary interventions for PMOP in Southwest China. Future research should validate these findings through multicenter studies.
