Sleep-disordered breathing and caffeine consumption: results of a community-based study

R Nisha Aurora et al, Sleep-disordered breathing and caffeine consumption: results of a community-based study, Chest, 2012, published online ahead of print.

Sleepiness is one of the most burdensome symptoms of sleep-disordered breathing (SDB). While caffeine is frequently used to avert sleepiness, the association between SDB and caffeine use has not been thoroughly explored. The current study examined whether SDB is associated with caffeine consumption and if factors such as sex, age, and daytime sleepiness explain or modify the association. Data was used from the Sleep Hearth Health Study, a community based study on the consequences of SDB. Caffeinated soda, but not tea or coffee intake, was independently associated with SDB severity. Compared to participants without SDB, the relative ratios for caffeinated soda consumption in women with mild, moderate, and severe SDB were: 1.20 (CI: 1.03-1.41), 1.46 (CI: 1.14-1.87), and 1.73 (CI: 1.23-2.42) respectively. For men, an association was only noted with severe SDB and caffeinated soda use. Age did not modify the SDB-caffeine association and sleepiness could not explain the observed associations. These authors concluded that, ‘SDB is independently associated with caffeinated soda use in the general community. Identifying excessive caffeine used in SDB has potential significance given the cardiovascular effects of caffeine and untreated SDB’.
