Researchers conducted a cross-cultural study of long-term care facilities and found several predictors of insomnia, according to an HCPLive report.
The researchers found that the prevalence of insomnia was 24%, with significant differences seen between countries. Older versus younger residents reported more insomnia complaints. In all countries, higher rates of insomnia were associated with hypnosedatives and depression, and in most countries higher rates correlated with stressful life events, fatigue, and pain. Activities of daily living, physical activity, and cognitive status were not associated with insomnia. After controlling for variables and country, age, depression, stressful life events, fatigue, pain, and hypnosedatives were independent significant predictors of insomnia.
