title: Sleep patterns in female adolescents with chronic musculoskeletal pain.
abstract: This study examined sleep patterns in female adolescents with chronic musculoskeletal pain. Twenty-six participants with chronic musculoskeletal pain completed questionnaires during their clinic visit, and three 24-Hour Sleep Patterns Interviews during the following 2 weeks. Compared to normative data (Acebo & Carskadon, 2002), adolescents with chronic pain reported similar total sleep time (TST) and bedtimes. However, study participants reported significantly longer sleep onset latency, more night wakings, a later morning wake time, and more symptoms of daytime sleepiness. Pain improved after sleep for 27% of the study sample, and was associated with longer TST. Finally, depression and anxiety were related to daytime sleepiness, but not total sleep time or sleep onset latency. Female adolescents with chronic pain either may be more sensitive to the chronic sleep debt that is common in this age group, or they may experience underlying physiological sleep disrupters (e.g., periodic limb movement disorder) or sleep abnormalities (e.g., alpha-delta intrusions) not measured in this study. Additional research is needed to examine the complex relation between sleep and chronic musculoskeletal pain.
