Do patients with the sleep apnea/hypopnea syndrome drink more alcohol?

As alcohol ingestion may worsen the sleep apnea/hypopnea syndrome, we have investigated the alcohol consumption of patients with the sleep apnea/hypopnea syndrome in comparison to control subjects to determine whether patients with the sleep apnea/hypopnea syndrome drink excessively. A lifetime alcohol history was taken from each. There was no significant difference between the 50 patients with the sleep apnea/hypopnea syndrome and 95 age-matched controls in either the lifetime (patients 27, SEM 5 x 10(3); controls 26, SEM 4 x 10(3) units) or current (12, SEM 2; 12, SEM 2 units per week) alcohol consumption. There was no evidence that alcohol consumption was related to the development of arterial carbon dioxide retention or peripheral edema in such individuals.
