Physical activity, nutrition, and dyslipidemia in middle-aged women

ABSTRACT

Cardiovascular disease is a major cause of death throughout the world. The aim of this study was to assess the prevalence of overweight/obesity, central obesity, hypertension and dyslipidemia, as well as dietary factors contributing to the development of dyslipidemia among middle-aged women. The research design of the present study was a population-based cross-sectional study; anthropometric measures and blood chemistry were obtained. Physical activity was measured using the original International Physical Activity Questionnaires Long Form while food frequency questionnaire [FFQ] was used in assessing individual's habitual intake. Overall, 809 women, 30-50 years of age from fourteen active urban Primary Healthcare Centers [PHC] in Babol City, northern Iran, were obtained from 1,905 households across operational areas of 14 PHC using systematic random sampling method. The prevalence rates of women classified as overweight/obese, with central obesity, hypertension and dyslipidemia were 82.8%, 75.5%, 14.6% and 63.4%, respectively. Total physical activity did not correlate with cholesterol ratio. Soybean protein was inversely associated with cholesterol ratio [rho=-0.18, P? 0.001]. The adjusted OR for dyslipidemia in women with moderate protein intake was significantly higher than in women with high and low intake [OR=2.31; 95% CI= 1.61, 3.30]. No significant associations were found between dyslipidemia and carbohydrate, fat intake or physical activity. This study showed very high prevalence of cardiovascular disease risk factors among Iranian middle-aged women. A more detailed study is suggested to develop definitively recommendations for the primary and secondary prevention of cardiovascular disease for the Iranian population
