Psychosocial risk factors for the metabolic syndrome: A prospective cohort study

Abstract Background/Objectives Metabolic deregulations and development of metabolic syndrome may be an important pathway underlying the relationship between stress and cardiovascular disease. We aim to estimate the effect of a comprehensive range of psychosocial factors on the risk of developing metabolic syndrome in men and women. Methods The study population consisted of 3621 men and women from the Copenhagen City Heart Study who were free of metabolic syndrome at baseline and reexamined after 10 years. The data was analyzed by multivariable logistic regression models adjusted for age, education, income, menopausal status and life style factors. Results We found major life events in adult life (OR 1.48, 95% CI 0.93 to 2.36) and major life events at work (OR 2.75, 95% CI 1.38 to 5.50), lacking a confidant (OR 1.94, 95% CI 1.07 to 3.53) and dissatisfaction with social network (OR 1.53, 95% CI 1.11 to 2.11) to be risk factors for developing the metabolic syndrome in women, while vital exhaustion (OR 2.09, 95% CI 0.95 to 4.59) and intake of sleep medications (OR 2.54, 95% CI 0.92 to 5.96) may play a more important role in men. Conclusions Experiencing major life events in work and adult life and/or dysfunctional social networks is a risk factor for metabolic syndrome in women, and stress reactions such as vital exhaustion and intake of sleep medications may play a more important role in the development of metabolic syndrome men.
