Abstract

Purpose

The aim of the study is to examine the health-related quality-of-life (HRQOL) impact of the nocturnal awakenings and the duration of the sleep in the Finnish middle-aged and older population.

Methods

Cross-sectional sample consisted of 823 community-dwelling persons aged 55–75 living in a single municipality in a rural area of Eastern Finland. Frequency of the nocturnal awakenings was dichotomized as reporting “frequent,” if the participant reported subjectively awakening “often” or “very often,” and “infrequent” if the participant reported awakening “sometimes” or less frequently. HRQOL was measured with a preference-based HRQOL-index instrument, 15D. Analyses were adjusted for gender, BMI, morbidities, depression, employment and marital status, current smoking and drinking, exercise, recommendation to exercise from a health care professional, and subjective opinion about own exercise habits.

Results

Frequent nocturnal awakenings had statistically and clinically significant negative impact on HRQOL, the mean (SE) adjusted marginal HRQOL impact being −0.0416 (0.006). More than 10 and less than 6.5 h of daily sleep were associated with higher probability of having low HRQOL, adjusted odd ratios (95 % CI) being 2.65 (1.11–6.33) and 2.65 (1.55–4.52), respectively. However, the changes in daily sleep duration did not have noticeable influence on the significance or magnitude of the negative HRQOL impact of the frequent nocturnal awakenings.

Conclusions

Nocturnal awakenings displayed a strong independent association with decreased HRQOL. The findings suggest that both clinicians and researchers should pay closer attention to nocturnal awakenings and other sleep problems in order to find ways to improve the quality of life in individuals with such conditions.
