Methods The data from family health questionnaire of health service survey in Western China in 2008 were descriptively analyzed. Results The two-week prevalence rate was 216.9‰ and the two-week hospital visit rate was 211.5‰. The sick people who did not seek medical care accounted for 56.2% among the sick population. The chronic disease prevalence rate was 226.4‰. The annual hospitalization rate was 77.1‰. Conclusion During the past five-year from 2003 to 2008, the needs of health services in Chongqing have had no big change, but the chronic disease prevalence rate has been in uptrend, and the utilization has obviously increased.
