ABSTRACT

Objective To learn the current situation of Quality of Life (QoL)among patients with various Chronic Diseases (CDs)and the effects of CDs on QoL.Methods Data was from the fifth health service survey in Ningbo City with self -reported CDs cases and QoL was measured by EQ -5D scale.Semi -parameter Additive Models and Semi -parameter Generalized Additive Models (GAMs)were used to analyze influencing factor of QoL.Results Different CDs had different effects on EQ -5D index,with the most severe impairments for stroke which was followed by tumor,COPD,diabetes and hypertension successively.Stroke,tumor and diabetes could improve the probability of self -reporting "problems"in all five dimensions (including mobility,self -care,usual activities,pain/discomfort and anxiety/depression dimension)and COPD could only increase the probability of self -reporting "problems"in dimension of usual activities.Hypertension could affect the other four dimensions except for the dimension of anxiety/depression.The relationship between Body Mass Index (BMI)and EQ -5D index was appeared inversed U -shaped with the maximum EQ -5D index located around the BMI of 20.90.Conclusion Different CDs had different effects on QoL and reaching optimal BMI was beneficial to improve the QoL.
