Impact of multimorbidity on the use of sleep medications among women: a population-based study in Southern Brazil.

The presence of multimorbidity increased the probability of using sleep medications by approximately 80%, regardless of the observed cutoff point, inclusion of obesity in multimorbidity, and adjustment for CMD. Specific aspects of some chronic conditions may interfere with sleep quality, predisposing women to begin use of these medications at early ages and, consequently, to continue their use throughout later life.
