Darling, the doctor says I slept well but I still have headache in the morning: an actigraphic study in couples

摘要

Morning headache (MH) affects about 5 % of the general population [1] and have been related to insomnia symptoms. Snoring and obstructive sleep apnea syndrome (OSAS) are frequent sleep disturbances and may cause also impaired sleep quality in bed partners. To date, prospective data on subjective and objective sleep quality in individuals with MH are lacking. Hence, the objective of this prospective actigraphic study was to compare sleep data of nights preceding days with and without MH in habitual snorers and their bed partners. We recruited habitual snorers and their non-snoring bed partners via newspaper articles. The participants completed a semistructured interview, filled in questionnaires about sleep quality, daytime sleepiness, depression and anxiety. Simultaneous actigraphy and sleep diaries were recorded during a 14-day period in these couples. Forty five (11 female) snorers and 45 (34 female) bed partners with a mean age of 47卤13 and 43卤12 years were included in this study. Apnea screening yielded snoring without OSAS, mild OSAS, moderate OSAS and severe OSAS in 27 (60%), 8 (18%), 3 (7%) and 6 (15%) snorers. MH occurred on 6.3% and 4.9% of the recorded days in snorers and bed partners, respectively. In snorers, sleep efficiency (85卤9 vs. 84卤9, p=0.5) and fragmentation indices (34卤16 vs. 36卤14, p=0.5) did not differ significantly between nights followed by MH and nights not followed by MH. Bed partners showed a significantly higher sleep efficiency (86卤8% vs. 89卤6%, p=0.04) and lower fragmentation index (33卤16 vs. 26卤12, p=0.01) during nights, which were followed by MH compared to nights not followed by MH. In contrast to previous reports our prospective data do not confirm the relationship between insomnia and MH. In fact, bed partners of habitual snorers had even slept more efficiently if they reported MH the following day.
