Abstract：Objective To explore the prevalence rate and influencing factors of chronic diseases among rural residents in Heilongjiang Province so as to provide suggestions for conducting chronic disease prevention and control in rural areas. Methods We collected the data from the Fifth National Health Service Survey. A stratified cluster random sampling method was used to select 13,498 rural residents from 4,801 households in Heilongjiang Province. All the family members of each household were interviewed face-to-face by the trained qualified investigators, and the contents of the questionnaire mainly included the family members’ social economic characteristics, medical insurance and the prevalence of chronic diseases in the residents. All the questionnaires were retrieved, and SAS9.2 software was employed for statistically analyzing the prevalence and influencing factors of chronic diseases. Results The prevalence rates of chronic diseases based on calculating the number of persons and the number of cases were 252.4‰ and 349.4‰ respectively, of which the prevalence rates of males and females were 312.9‰ and 386.8‰ respectively. Multi-factor analysis showed that compared with the age of less than 35 years, the age of 35-<65 years (OR=7.604, 95%CI:6.077-9.516, P=0.000) and the age of 65 years and above (OR=17.254, 95%CI:13.195-22.563, P=0.000) were the risk factorsfor suffering from chronic diseases. The older the age, the higher the prevalence rate of chronic diseases. Compared with the single, the married (OR=1.884, 95%CI:1.312-2.704, P=0.001) and the divorced or widowed (OR=2.246, 95%CI:1.504-3.353, P=0.000) had higher prevalence rates of chronic diseases. Compared with the illiteracies, the higher the residents’ educational level, the lower the prevalence rate of chronic diseases (all OR<1, all P<0.05). The residents with medical insurance had a higher prevalence rate of chronic diseases (OR=1.587, 95%CI:1.060-2.376, P=0.025). Compared with the residents living less than 1 kilometer away from the nearest medical instituion, those living more than 5 kilometersshowed a higher prevalence rate awall (OR=1.567, 95%CI:1.103-2.227, P=0.012). Compared the residents with the per capita housing area less than 20 square meters, those with more than 36 square meters had a higher prevalence rate (OR=1.500, 95%CI:1.295-1.737, P=0.000). The higher the per capita annual income, the lower the prevalence rate of chronic diseases (all OR<1, all P<0.05). Drinking induced a higher prevalence rate of chronic diseases (OR=1.160, 95%CI:1.042-1.986, P=0.030). Conclusions The prevalence rate of chronic diseases in the rural residents in Heilongjiang Province is high. The females, the elderly, the divorced or widowed, residents with poor educational background, the uninsured and low-income residents are the key groups in great demand for health services.
