ABSTRACT
Objective To explore the relationship between socioeconomic status and the risk factors of cardiovascular diseases in retirees from a community in Shanghai. Methods Observational study involved 9 943 retirees aged 50 and over in Shanghai. Both single factor and multi-factor analyses methods were used to describe the correlation between factors as:educational level,marital status,annual household income and risk of hypertension,coronary heart disease,stroke etc. A new defined compound index was used to assess the relevance of socioeconomic status on the risk of cardiovascular diseases,based on logistic regression model. Results After adjusted for age,the risk of cardiovascular diseases in these retirees was influenced by socioeconomic status. In general, opponent correlations in education levels and prevalence of hypertension were found between female and male. Compared with those having received college or higher education,the risk of hypertension increased in females when the education level declined,with OR as 1.08(95%CI:0.89-1.30). For those having had senior high school junior high school or elementary education,the risks of hypertension were 1.26(95%CI:1.05-1.51),1.34(95%CI:1.08-1.65),0.72(95%CI:0.59-0.87),0.78 (95%CI:0.64-0.94),and 0.70(95%CI:0.52-0.92)for males,respectively. The risk of cardiovascular diseases increased with annual household income. Compared with high level of socioeconomic status, lower socioeconomic status might decline the risk of cardiovascular diseases in males by approximately 30%,with OR for medium being 0.72(95%CI:0.61-0.84)and for lower ones it was 0.70(95%CI:0.57-0.87). However,similar correlations were not found in females. No significant relationship was found between marital status and the prevalence of cardiovascular diseases in this study. Conclusion The risks of cardiovascular diseases varied with different socioeconomic status, indicating that tailored interventions should be conducted in different socioeconomic groups.
