[BDSP. Notice produite par INIST-CNRS 99Dr7R0x. Diffusion soumise à autorisation]. Chronic obstructive pulmonary disease mortality and risk factors were studied in a nationally representative sample of 169,871 Chinese men and women aged 40 years or older. Baseline data were collected in 1991 by using a standard protocol, and a follow-up evaluation was conducted in 1999-2000, with a response rate of 93.4%. Age-standardized mortality (per 100,000 person-years) was 179.9 for men and 141.3 for women. After adjustment for important covariables, the respective relative risks of chronic obstructive pulmonary disease-related mortality for baseline risk factors in men and women were 2.80 (95% confidence interval (Cl) : 2.64,2.98) and 2.71 (95% Cl : 2.53,2.89) for each 10-year increase in age, 0.84 (95% Cl : 0.74,0.95) and 1.44 (95% Cl : 1.07,1.95) for alcohol consumption, 1.18 (95% Cl : 1.04,1.35) and 1.77 (95% Cl : 1.45,2.15) for>20 pack-years of smoking, 2.37 (95% Cl : 1.91,2.94) and 2.47 (95% Cl : 1.66,3.67) for non-high-school graduation, 1.57 (95% Cl : 1.38,1.79) and 1.35 (95% Cl : 1.17,1.56) for physical inactivity, 2.66 (95% Cl : 2.34,3.02) and 2.60 (95% Cl : 2.25,3.00) for underweight, 1.39 (95% Cl : 1.23,1.57) and 1.73 (95% Cl : 1.50,2.00) for living in northern China, and 2.14 (95% Cl : 1.86,2.46) and 1.79 (95% Cl : 1.55,2.07) for living in rural China. This study indicated that cigarette smoking, low educational level, physical inactivity, and underweight are important modifiable risk factors for chronic obstructive pulmonary disease-related mortality in China.
