Abstract

OBJECTIVE:

We aimed to find how self-reported sleep (measured by the St. Mary's Hospital Sleep Questionnaire) in postmenopausal women having hot flash activity was related to objective sleep (actigraphy), psychological and somatic symptoms [Women's Health Questionnaire (WHQ)], and cognitive test performance (computerized tests). A secondary aim was to find if self-reported sleep showed expected correlations with hyperarousal (Hyperarousal Scale).

DESIGN:

Drug trial baseline data from 88 healthy, postmenopausal women were retrospectively analyzed. Multivariate regression was used to adjust for confounder variables and test whether differences in self-reported sleep measures were systematically associated with differences in objective sleep, WHQ symptom measures, or cognitive test performance scores.

RESULTS:

Increased self-report scores for low sleep quality were associated with an increased risk of WHQ symptoms and reduced cognitive test performance. Self-reported sleep measures showed little correlation with their analogous objective measures. Self-reported low sleep quality proved most closely associated with the WHQ symptoms of tiredness, clumsiness, and difficulty concentrating. Women whose self-reported sleep-onset latency times were longer than the median overestimated their objective sleep onset time by 30 min, whereas the other women underestimated theirs by 15 min (P < 0.0001). Women whose self-reported total sleep was longer or shorter than the median, respectively, underestimated objective sleep times by 9 and 71 min (P < 0.0001). High hyperarousal scores were associated with underestimations of objective sleep.

CONCLUSION:

Self-reports of lower sleep quality were associated with increased WHQ psychological and somatic symptom measures and decreased cognitive test performance more than with differences in objective sleep. Self-reported trouble sleeping may signal problems independent from objectively low sleep quality, such as subjective distress or diminished cognitive function.
