Socio-economic position and cardiovascular risk factors in an Italian rural population

Abstract

Cardiovascular disease (CVD) is the leading industrial world cause of mortality. Lower social class groups have higher incidence of CVD and also display less favourable risk factor profiles. To investigate the association and gradient between major cardiovascular risk factors (smoking habit, serum lipid profile, blood pressure, relative body weight) and socio-economic position (proxy measures selected: education and occupation) data on 2592 men and 2866 women were analysed. The effect of potential confounding factors and effect modifiers was estimated. Linear and logistic regression modelling was performed for continuous and dichotomous outcomes respectively. The lower the grade of employment or the level of education, the higher was the prevalence of obesity in the study population. The association was stronger in women than in men. Higher education was associated with a lower prevalence of smoking among men and a higher prevalence among women. Systolic blood pressure was negatively related to socio-economic position in both men and women in the age-adjusted models. Attention should be concentrated on socio-economic differences in obesity and blood pressure in this population.
