Clase social, desigualdades en salud y conductas relacionadas con la salud de la población trabajadora en Chile

Objective. To analyze links between social class and health-related indicators and behaviors in Chilean workers, from a neo-Marxian perspective. Methods. A cross-sectional study based on the First National Survey on Employment, Work, Health, and Quality of Life of Workers in Chile, done in 2009-2010 (n = 9 503). Dependent variables were self-perceived health status and mental health, examined using the General Health Questionnaire (GHQ-12). Health-related behavior variables included tobacco use and physical activity. The independent variable was neo- Marxian social class. Descriptive analyses of prevalence were performed and odds ratio (OR) models and 95% confidence intervals (95%CI) were estimated. Results. Medium employers (between 2 and 10 employees) reported a lower prevalence of poor health (21.6% [OR 0.68; 95%CI 0.46-0.99]). Unskilled managers had the lowest mental health risk (OR 0.43; 95%CI 0.21-0.88), with differences between men and women. Large employers (more than 10 employees) reported smoking the least, while large employers, expert supervisors, and semi-skilled workers engaged in significantly more physical activity. Conclusions. Large employers and expert managers have the best health-related indicators and behaviors. Formal proletarians, informal proletarians, and unskilled supervisors, however, have the worst general health indicators, confirming that social class is a key determinant in the generation of population health inequalities.
