title: [Quality of life and related influencing factors in Chinese adults].
abstract: OBJECTIVE
  To evaluate the quality of life (QOL) and influencing factors on Chinese adults.
  
  
  METHODS
  83 666 subjects from 2010 Chronic Non-communicable Disease and Risk Factor Surveillance Project in China were included in this study. Questionnaire was used to collect information on general condition and health status. WHOQOL-BREF was adopted as an instrument to measure the QOL on all the subjects.t test was used to compare QOL from different groups. Multiple linear regression analysis was used to assess the association of QOL with BMI, by gender.
  
  
  RESULTS
  Among all the 83 666 subjects, mean scores of physical,psychological, social relationship and environment domains appeared as (73.97 ± 13.84), (66.65 ± 14.21), (65.76 ± 14.08) and (56.59 ± 15.15), respectively. Age, residential areas (urban/rural), education levels and marital status all showed significant impact on scores of the four domains (P<0.05). Scores decreased with age and increased with education level (P<0.05). Scores of rural adults were greater than those from the urban and the scores of married or cohabiting adults were greater than the other groups (P<0.05). Physical and psychological scores were lower in women than that of in men (P<0.05). Except for environment domain, scores of patients with chronic diseases were much lower than those without.
  
  
  CONCLUSIONS
  Factors as age, residence (urban/rural), education levels, marital status and chronic diseases could significantly influence the QOL of Chinese adults.
