Background: To our knowledge, there are no previous data on drinking problems in patients with pneumoconiosis. The aim of this study was to examine drinking patterns and the impact of drinking on lung function and health‐related quality of life (HRQOL) in Chinese patients with pneumoconiosis. Methods: Three hundred patients with pneumoconiosis were recruited from a community‐based case registry. The HRQOL was measured with the St. George's Respiratory Questionnaire (SGRQ). Pulmonary function, comorbidity, and psychosocial variables were also assessed. The alcohol use of the patients was evaluated with the Alcohol Use Disorders Identification questionnaire. Results: Of the 300 patients, 72.3% (217) reported that they had not consumed any alcohol during the past year, whereas 83 patients (27.7%) did report drinking alcohol. In the drinking group, 88.0% (73) consumed <7 standard drinks per week, and none of them exceeded the safety limit of 21 standard drinks per week. The drinking group ( n = 83) was younger, had less concurrent medical diseases, and lower (i.e., better) unadjusted SGRQ symptom, activity, impact, and total scores than the nondrinking group ( n = 217). The SGRQ scores, which were adjusted for age, duration of occupation, concurrent medical diseases, smoking status, and forced expiratory volume in 1 sec predicted tests (FEV 1 %), remained significantly lower for the drinking group. Although the drinking group had a higher unadjusted FEV 1 % predicted, the difference between the FEV 1 % of the two groups, after adjustment for covariates, was of borderline significance only. Conclusions: Most Chinese patients with pneumoconiosis in this study did not consume alcohol, and among those who did, the level of alcohol consumption was low. This low level of alcohol consumption was associated with a better HRQOL and possibly with better lung function.
