Abstract Mkid 151

The present study, a questionnaire survey, was undertaken to assess the simultaneous influence of burning mouth syndrome (BMS) and nocturia on the four variables: sleep (poor vs. good) awakenings (often vs. seldom or never), the ability to fall asleep after nocturnal awakenings (easy vs. difficult) and nightmares (often vs. seldom or never) in a large group of elderly persons. The survey comprised 6,103 elderly men and women (39.5% men) of ages (mean±standard deviation) 73.0±6.0 and 72.6±6.7 years, respectively. Poor sleep was reported by 14.4% of the men and 28.1% of the women (p<0.0001). BMS was reported by 5.7% (2.4% of the men and 8.5% of the women; p<0.0001). The occurrence of poor sleep was not related to BMS in men, but was 2.8 (1.8-4.3) times more common in women with BMS than in those without. Nightmares were 3.5 (1.2-11.0) times more common in men and 5.2 (3.0-9.0) times more common in women with BMS than in those without BMS. The occurrence of poor sleep was increased in both men and women who either had ≥3 micturition episodes at night or were often troubled with BMS, and was further increased in those who reported both. It is concluded that BMS and nocturia are both independently involved in deterioration of sleep in the elderly and that BMS has a significant influence on the occurrence of nightmares
