Third,130 household were chosen. A total of 3912 subjects were selected as survey sample. Information on demographics, the health status and other factors were collected through face-to-face questionnaire interview. Logistic regression was used to estimate the odds ratios (ORs) and 95% CIs of chronic diseases in relation to corresponding factors.Results:1 Among 3912 participants,470 participants were patients with chronic diseases, including 199 males and 271 females. The prevalences of chronic diseases in total population, males and females were 12.01%,10.21% and 13.08%, respectively.

Comparing with persons aged 15-34 years, the ORs (95% CIs) of chronic diseases for persons aged 35-44 years,45-54 years and 55-59 years were 4.807(3.276-7.053),10.327 (7.203-14.806),19.556(13.217-28.936), respectively. Females (OR=1.410,95%CI: 1.161-1.713) was related to a higher risk of chronic diseases than males. In the urban citizens, the prevalent of chronic diseases increased with the rising economic levels, the OR (95% CI) of chronic diseases in the groups with average monthly incomes of 5000-9999 RMB and=10000 RMB were 1.795(1.369-2.353) and 1.789(1.279-2.503) respectively comparing with the group of<5000 RMB/month income. 3 88% of patients with chronic diseases received medical treatment.
