February 16, 2009 — Sleep-seeking behavior to relieve pain may contribute to the development of insomnia in people with tension-type headache, according to the results of a study published in the February 15 issue of the Journal of Clinical Sleep Medicine.
"Insomnia has been identified as a risk factor for tension-type headache, although the pathogenesis of sleep disturbance in this population is unclear," write Jason C. Ong, PhD, from Rush University Medical Center in Chicago, Illinois, and colleagues. "The present study examined pain-related self-management strategies in a nonclinical, young-adult sample for preliminary evidence to support a novel hypothesis for the development of insomnia in this population."
The study sample consisted of 32 women with tension-type headache and 33 women with minimal pain who served as control subjects. The investigators studied self-report data on headache triggers, pain interference with sleep, and self-management strategies for pain.
Compared with the control group, the headache group had a significantly greater proportion of participants who reported sleep problems as a trigger of headaches, stress as a trigger of headache, and going to sleep as a strategy for dealing with pain. Ratings of pain interference with sleep were significantly higher in the headache group. Among the headache group, 81% reported that going to sleep was the most frequently used self-management strategy, and this group also rated going to sleep as the most effective strategy (5.5/7.0).
