Abstract:
Objective:To research the association between exposure to solid fuels for heating and its duration and the risk of respiratory diseases morbidity.Methods:Data from the China Kadoorie Biobank project sited in Pengzhou City, Sichuan Province. Cox proportional hazard regression model was used to analyze the association between exposure to solid fuels for heating and its duration and the risk of total respiratory diseases and the association between exposure to solid fuels for heating and the risk of chronic obstructive pulmonary disease (COPD) and pneumonia among respiratory diseases.Results:A total of 46 082 participants aged 30-79 years were enrolled, with 11 634 (25.25%) heating during the winter, of whom 8 885 (19.28%) used clean fuels and 2 749 (5.97%) used solid fuels, of whom 34 448 (74.75%) did not heat. After controlling for multiple confounding factors, Cox proportional hazard regression model was used, which revealed that compared with clean fuels, unheating could reduce the risk of total respiratory disease ( HR=0.81,95% CI:0.77-0.86), COPD ( HR=0.86,95% CI:0.78-0.95) and pneumonia ( HR=0.80,95% CI:0.74-0.86), respectively. Exposure to solid fuels increased the risk of total respiratory disease ( HR=1.10, 95% CI:1.01-1.20) and were not associated with COPD and pneumonia. Compared with no solid fuel exposure, the risk of total respiratory disease (1-19 years: HR=1.23, 95% CI:1.10-1.37; 20-39 years: HR=1.25, 95% CI:1.16-1.35; ≥40 years: HR=1.26, 95% CI:1.15-1.39) and COPD (1-19 years: HR=1.21, 95% CI:1.03-1.42; 20-39 years: HR=1.30, 95% CI:1.16-1.46; ≥40 years: HR=1.35, 95% CI:1.18-1.54) increased with the length of exposure of solid fuels (trend test P<0.001). Solid fuels exposure for 1-19 years and 20-39 years increased the risk of COPD by 23% ( HR=1.23,95% CI:1.02-1.49) and 16% ( HR=1.16, 95% CI:1.00-1.35). Conclusion:Heating solid fuels exposure increases the risk of total respiratory disease, COPD, and pneumonia.
