Purpose
The increase in cardiovascular risk after the menopausal transition remains partly explained until today. Further research is needed to identify risk factors potentially modifiable by primary prevention practices. This cross-sectional study, part of a larger prospective project, aims to investigate possible associations between dietary patterns and indices of vascular structure and function among healthy postmenopausal women.
Methods
Postmenopausal women (n = 310) without clinically overt cardiovascular disease were recruited consecutively from a University Menopause Clinic over three years. Dietary intake was assessed by a validated food frequency questionnaire and the MedDietScore. In addition, we assessed anthropometric/biochemical parameters, including the Triglyceride-glucose index (TyG-Index), body fat distribution [triceps skinfold (TSF), mid-upper arm circumference (MUAC)] and physical activity. The vascular assessment included carotid-femoral pulse wave velocity (PWV), carotid and femoral-artery intima-media thickness (IMT) and atheromatous plaques presence.
Results
Consumption of non-refined cereals was associated with carotid-bulb IMT (R2 = 5.5% b-coefficient = −0.142; p = 0.011), adjusting for age, physical activity, lipids, systolic blood pressure, smoking, body mass index, insulin resistance, and daily energy intake. PWV was associated with the intake of total dairy products (R2 = 27.3%, b-coefficient = −0.117; p = 0.017). Higher red meat consumption was related to a greater TyG-index (Model 1, R2 = 14.3%, b-coefficient=0.121; p = 0.048), an association mediated by total daily energy intake. Higher consumption of alcohol, as well as the MedDietScore, were inversely associated with TSF measurements, significant after Bonferroni correction.
Conclusion
Dietary patterns are associated with metabolic indices and subclinical atherosclerosis in postmenopausal women independently of traditional cardiovascular risk factors, total energy intake or physical activity.
