BACKGROUND: We investigated the effects of marital status and education on the risk of @entity583 ( @entity583 ) in a large-scale case-control study in China. METHODS: This study was part of the INTER-HEART China case-control study. The main outcome measure was first @entity583 . Incident cases of @entity583 and control @entity1 with no past history of @entity299 were recruited. Controls were matching by age (  5 years) and sex. Marital status was combined into 2 categories: single and not single. Education level was classified into 2 categories: 8 years or less and more than 8 years. RESULTS: From 1999 to 2002, we recruited 2909 cases and 2947 controls from 17 cities. After adjustment for age, sex, BMI, psychosocial factors, lifestyle, other factors, and mutually for other risk factors, the odds ratio (OR) for @entity583 associated with being single was 1.51 (95% confidence interval: 1.18-1.93) overall, 1.19 (0.84-1.68; P = 0.072) in @entity1 and 2.00 (1.39-2.86; P < 0.0001) in @entity1 . The interaction of sex and marital status was statistically significant (P = 0.045). Compared with a high education level, a low education level increased the risk of @entity583 (1.45, 1.26-1.67); the odds ratios in @entity1 and @entity1 were 1.29 (1.09-1.52) and 1.55 (1.16-2.08), respectively. Single @entity1 with a low education level had a high risk of @entity583 (2.95, 1.99-4.37). CONCLUSIONS: Being single was consistently associated with an increased risk for @entity583 , particularly in @entity1 . In addition, as compared with high education level, low education level was associated with a higher risk of @entity583 in both @entity1 and @entity1 .
