Abstract: | Objectives: To investigate the relationship between habitual physical activity and dietary intake, body composition, metabolic and hormonal variables, and cardiovascular risk factors in postmenopausal women with no evidence of cardiovascular disease. Methods: In this cross-sectional study, 105 women (mean age: 55.2 ± 4.9 years) consulting for climacteric symptoms underwent anthropometric and hormonal assessment. Usual dietary intake was assessed with a food frequency questionnaire and habitual physical activity was assessed with a digital pedometer. Participants were classified as physically inactive (<6000 steps daily) or physically active (≥6000 steps daily). Results: Compared to the inactive group, active women had higher protein, total fat, cholesterol, iron, calcium, and the antioxidant micronutrients zinc and selenium intake as well as differences on food groups: higher meat, egg, and whole-dairy intake and lower intake of chips. Active participants also presented lower diastolic blood pressure (p = 0.012), ultrasensitive C-reactive protein (us-CRP; p = 0.011), fasting glucose (p = 0.003), fasting insulin (p = 0.019), and homeostasis model assessment index (p = 0.017). After adjustment for age and time since menopause, the risk for metabolic syndrome increased with physical inactivity (odds ratio OR] = 3.55, 95% confidence interval CI], 1.08–11.66), us-CRP (OR = 6.57, 95% CI, 2.20–19.56), and percentage body fat (OR = 5.65, 95% CI, 1.19–28.89). Conclusion: Both physical activity and dietary choices may have contributed toward a more favorable cardiovascular profile and lower risk of metabolic syndrome in postmenopausal women. |
