To the Editor: Although acute alcohol ingestion is known to aggravate the severity of sleep-disordered breathing (SDB), no population-based epidemiologic study has been conducted to examine the effect of usual alcohol consumption.1 We investigated the association between usual alcohol consumption and nocturnal oxygen desaturation.
Methods
Participants were recruited for a sleep study as a population-based sample from the 2000 to 2002 annual cardiovascular risk surveys of men in 3 Japanese communities. Participants were required to be 40 to 69 years old. Of the 1741 men eligible, 1517 (87%) agreed to participate.
A pulse oximeter (PULSOX-3Si, Minolta Co, Osaka, Japan) was attached to the wrist and index finger during all-night sleep at home. Every second it recorded a 5-second moving average of arterial blood oxygen saturation; thus, sampling time was short enough for accurate estimation of oxygen saturation.2 We used a sleep diary to exclude waking time from the analysis to minimize . . .
