[Socioeconomic inequalities and age and gender differences in cardiovascular risk factors].

Objective: To describe the cardiovascular risk factors in a working population in the Balearic Islands and to examine whether differences by social class vary according to age and gender.

Methods: A cross-sectional study was carried out in a sample of active workers aged 20-65 years in the Balearic Islands. The participants were included in the study during their annual work health assessment in 2011. The following variables were collected: occupation, social class, age, gender, height, weight, smoking, blood pressure, lipid profile, and glucose levels. Cardiovascular risk was calculated using two different equations (Framingham and REGICOR).

Results: Differences by social class were observed for most cardiovascular risk factors. The pattern of these differences differed depending on age group and gender. Differences in obesity by social class increased with age in women but decreased in men. More differences in hypertension by social class were found among women than among men, with differences increasing with age in both genders. Significant differences by social class were found among women in lipid profile, and these differences increased with age, mainly for low levels of high-density lipoprotein-cholesterol.

Conclusions: Inequalities in cardiovascular risk factors by social class were higher among women than among men. Some cardiovascular risk factors such as smoking and obesity showed significant inequalities from a very early age.
