Abstract


Background: To examine the association of combined dietary patterns with physical activity on sarcopenia in menopausal women.

Methods: In this cross-sectional study, 250 menopausal women aged 45–75 were studied. Dietary intakes were assessed with a validated 147-item food frequency questionnaire, and dietary patterns were identified by a principal component factor analysis method. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). Sarcopenia was defined, according to the European Working Group on Sarcopenia in Older People (EWGSOP) criteria, as the presence of low muscle mass, plus low muscle performance, or low physical strength.

Results: two major dietary patterns were found: a prudent pattern (high in vegetable, vegetable oil, fish, dairy, legume, nut, animal protein and fruit), and a western pattern (high in commercial beverage, hydrogenated fat, sugar, sweet-snack, potato, tea-coffee and refined grain). After adjusting for age, we found a significant interaction between the western pattern and physical activity status with the odds of sarcopenia (P-interaction = 0.01) which was higher in active women than those who were inactive, but there was no significant difference between inactive and active participants in the prudent pattern (P-interaction = 0.90).

Conclusion: increasing physical activity was associated with higher odds of sarcopenia in the western pattern among menopausal women.
