Univariate analysis showed that there was a significant difference on the total knowledge scores among community residents with different ages, education level, marital status, occupation and monthly family income (P<0.05);Women and participants with the prevention of chronic diseases in daily life had more positive attitudes towards AF (P<0.05);There was a significant differenceon the total score of health behaviorsamong community residents with different educational level, monthly family income and prevention of chronic diseases(P<0.05);Pearson correlation analysis showed that there was a significant positive correlation between knowledge and health behaviorsof AF (r=0.337, P=0.000).
