A total of 374 postmenopausal women were randomly selected from 13 geographical clusters in Bushehr port. Serum visfatin and adiponectin were determined with an enzyme-linked immunosorbant assay technique and current dietary intake was recorded with a food frequency questionnaire and a 3-day recall. Each food and beverage was analyzed for macro- and micronutrient content.
Bivariate correlation analysis showed a correlation between serum visfatin level and dietary SFA, n-6 PUFA and cholesterol intake. In multiple regression analyses, serum visfatin levels showed a significant positive correlation with dietary SFA (β=0.06, p=0.01), PUFA (β=0.02, p=0.02) and cholesterol (β=0.005, p=0.002) after controlling for age, diabetes, total energy intake and BMI. There was no significant relationship between dietary MUFA intake and serum visfatin level. No significant correlations were found between age- and BMI-adjusted adiponectin and dietary SFA, MUFA or n-6 PUFA intake (p>0.05).
We found a positive relationship between dietary SFA, PUFA and cholesterol with serum visfatin level in postmenopausal women, and conclude that the postmenopause-induced inflammatory responses may be modulated at least in part by dietary modification.
