Description
Summary:OBJECTIVETo assess the modifying effect of marital status on social and gender inequalities in mortality from diabetes mellitus (DM) in Andalusia. MATERIAL AND METHODSA cross-sectional study was conducted using the Andalusian Longitudinal Population Database. DM deaths between 2002 and 2013 were analyzed by educational level and marital status. Age-adjusted rates (AARs) and mortality rate ratios (MRRs) were calculated using Poisson regression models, controlling for several social and demographic variables. The modifying effect of marital status on the association between educational level and DM mortality was evaluated by introducing an interaction term into the models. All analyses were performed separately for men and women. RESULTSThere were 18,158 DM deaths (10,635 women and 7,523 men) among the 4,229,791 people included in the study. The risk of death increased as the educational level decreased. Marital status modified social inequality in DM mortality in a different way in each sex. Widowed and separated/divorced women with the lowest educational level had the highest MRRs, 5,1 (95%CI: 3,6-7,3) and 5,6 (95% CI:3,6-8,5) respectively, while single men had the highest MRR, 3,1 (95%CI: 2,7-3,6). CONCLUSIONSEducational level is a key determinant of DM mortality in both sexes, and is more relevant in women, while marital status also plays an outstanding role in men. Our results suggest that in order to address inequalities in DM mortality, the current focus on individual factors and self-care should be extended to interventions on the family, the community, and the social contexts closest to patients.
