Pulmonary symptoms associated with heavy alcohol consumption among people living with HIV: an analysis of the NHANES 1999–2010

Aim This matched case–control study aimed to provide epidemiologic evidence of increased burden of respiratory symptoms and pulmonary function decline among people living with human immunodeficiency virus (HIV) and a history of heavy alcohol consumption. Methods Cases were participants with HIV (PWH; n = 75, 33%), and controls were participants without HIV (PWoH; n = 150, 67%). PWH were matched to PWoH by age and sex in the ratio of 1:2. Eligible participants responded to the respiratory health National Health and Nutrition Examination Survey questionnaire [prolonged coughs (≥3 months), bringing up of phlegm (≥3 months), and a history of wheezing or whistling in the chest (past year)]. The effects of both alcohol and HIV on participants’ pulmonary function were determined using linear regression analysis. Results History of heavy alcohol consumption was more prevalent among PWH (40%) compared to PWoH (27%). PWH who had a history of heavy alcohol consumption had a higher prevalence of coughing most days (45% vs. 4%, P = .0010), bringing up phlegm most days (31% vs. 0%, P = .0012), and wheezing or whistling in the chest (40% vs. 20%, P = .058) compared to participants who did not heavily consume alcohol. Furthermore, a history of heavy alcohol consumption was associated with decreased forced expiratory volume (ml) in 1 s/forced vital capacity among PWH (β = − 0.098 95% C.I. −0.16, −0.04, P = .03) after adjusting for having smoked at least 100 cigarettes in life. Conclusion A history of heavy alcohol use increased respiratory symptoms and suppressed pulmonary function among people living with HIV. This study provides epidemiological evidence of the respiratory symptom burden of people living with HIV who have a history of heavy alcohol consumption.
