Epidemic characteristics in population with high risk of chronic disease in China
Objective To understand the epidemic characteristics in population with high risk of chronic disease in China,and provide the theoretical basis for health management and lifestyle intervention for people with high risk of chronic diseases in the community.Methods The data were from China Chronic Diseases and Risk Factors Surveillance(CCDRFS).Multi-stage stratified cluster random sampling method was used to select 184 876 residents(≥18 years old)from 298 monitoring sites of 31 provinces(autonomous region,municipality)as the subjects.The investigation was performed with questionnaire,physical examination and laboratory test.Rao-Scott x2 test and trend x2 test with weighted adjustment for complex sampling were used to analyze the data.The used software was SAS 9.4.Results Finally included subjects were 178 043 cases(78 641 males,44.2％;99 402 females,55.8％),the mean age was(43.6±16.1)years old.The detected rate of residents with high risk of non-communicable chronic disease was 68.4％(95％CI:67.6％-69.2％),the detected rate(82.2％,95％CI:81.3％-83.2％)in males was significantly higher than that(54.6％,95％CI:53.4％-55.7％)in females(P＜0.01).The detected rates of subjects with 55-74 years old,educational level primary school,retire and living in rural area were higher(P＜0.05).Among five high risk factors,the detected rate of high waistline was 35.2％(95％CI:34.3％-36.2％),the detected rate of current smoking was 26.3％(95％CI;25.7％-27.1％),the detected rate of high total cholesterol was 23.0％(95％CI:22.4％-23.7％),the detected rate of high blood pressure was 16.6％(95％CI:16.0％-17.2％),and the detected rate of high fasting blood glucose was 10.0％(95％CI:9.2％-10.8％).Among all groups with high risk of non-communicable chronic diseases,53.6％(95％CI:52.7％-54.6％)of subjects had only one risk factor,32.8％(95％CI:32.2％-33.5％)of subjects had two risk factors,13.6％(95％CI:13.0％-14.1％)of subjects had three or more risk factors.There were significant differences in distribution of the number of high risk factors among subjects with different age,different gender,different educational levels,different areas and different jobs(P＜0.05).Conclusion The detection rate of high risk individuals with chronic diseases in China is high.Prevention and control strategies should be developed based on the epidemic characteristics of different populations to prevent or slow down the incidence of chronic diseases.
