Are sleep disorders hereditary? A questionnaire survey of elderly persons about themselves and their parents.
The aim of the present study was to investigate the occurrence of sleep complaints in an elderly population in relation to the sleep pattern in their parents. The study is based on a postal questionnaire, which was sent to 10,216 elderly persons in northern Sweden. The mean (s.d.) ages of the participating men and women were 73.0 (6.0) and 72.6 (6.7) years, respectively. Among the men whose parents had no sleep problems, a good night's sleep was reported by 11.1%, and among those whose parents both had such problems, this proportion was 18.9%. The corresponding figures for women were 20.6% and 60.0%, respectively. Restless sleep, frequent awakening, difficulty in getting to sleep again after waking up in the night as well as tiredness at night but with inability to get to sleep was more common in both sexes if either of the parents had difficulty in sleeping, and even more common if such problems had occurred in both parents. Also visits to doctors because of sleep problems and treatment with sleeping pills were more common in both men and women whose parents had had sleep problems, compared with those whose parents had been good sleepers. Thus, a poor sleep was more common in elderly persons if their parents had sleep problems, compared with those whose parents had been good sleepers. The results suggest that hereditary factors could be an underestimated cause of sleep disorders in the elderly.

Sleep and sleepiness 1 and 9 months after cataract surgery.
This study was undertaken to analyze sleep development in a group of patients during the first 9 months after cataract extraction. Men and women (n=407) undergoing cataract surgery at the Department of Ophthalmology, Sundsvall Hospital during two periods in 2000-2002 were asked to complete a questionnaire on the state and change of sleep and sleepiness 1 and 9 months after the operation. The response rate was 90.8%. The mean ages of the participating men and women were 74.5 and 75.6 years, respectively. One week after cataract extraction the visual acuity in the treated eye was 0.67 (+/-0.31) in men and 0.69 (+/-0.28) in women (NS), and showed an inverse relationship to age in both men (P<0.01) and women (P<0.0001). One month after cataract extraction 28.3% of the men and 37.5% of the women experienced poor sleep, and after 9 months the figures were 15.8 and 31.4%, respectively. Frequent awakenings and difficulty in falling asleep after nocturnal awakenings improved correspondingly. Being well rested in the morning increased and daytime sleepiness decreased. The results indicate that in elderly persons with cataract sleep is improved 1 month after cataract extraction and further improvement during the first 9 months may be experienced.

Visual impairment, sleep and nocturia in the elderly.
The aim of this study was to determine whether there was a relationship between visual impairment and nocturia in a group of elderly men and women. A questionnaire survey was undertaken among 10,216 elderly subjects. The mean (+/-S.D.) ages of the men and women were 73.0+/-6.0 and 72.6+/-6.7 years, respectively. Visual impairment was reported by 20.9% of the men and 32.9% of the women and was twice as common in men and 1.8 times more common in women of ages > or =80 as in those of ages <70 years. Occurrence of three or more nocturnal micturition episodes was 1.7 (1.2-2.3) times higher in men and 1.9 (1.5-2.4) times in women with visual impairment. In a multiple logistic regression analysis, significant independent correlates of three or more nocturnal micturition episodes versus two or fewer such episodes in men were: age, 70-79 years versus <70 years (odds ratio [OR] 1.6; confidence interval [CI] 1.1-2.6), age > or =80 years versus <70 years (1.7; 1.0-3.0), sleep, poor versus good (2.1; 1.4-3.2), and poor vision (1.8; 1.2-2.7). The corresponding odds ratios in women were: age 70-79 years versus <70 years (1.9; 1.3-2.7), age > or =80 years versus <70 years (2.1; 1.3-3.2), sleep, poor versus good (2.8; 2.1-3.7), and vision, poor versus good (1.6; 1.2-2.1).

The development of sleep in persons undergoing cataract surgery.
This study was undertaken in order to analyse sleep in a group of patients who were operated on for cataract. All patients (n=328) undergoing cataract surgery at the Department of Ophthalmology, Sundsvall Hospital during a 4-month period were asked to complete a questionnaire on the state and change of sleep and sleepiness 1 month after the operation. Twelve persons were unable or declined to participate. The response rate was 97.2%. The mean ages of the participating men and women were 74.5 and 76.3 years, respectively. Pre-operative visual acuity in the operated eye was 0.16 in men and 0.18 in women. After cataract extraction sleep was improved in 12.0% of the men and in 26.3% of the women. Nevertheless poor sleep 1 month post-operatively was reported by 29.3% of the men and 42.6% of the women (P<0.05). There was no age-related increase in sleep complaints. The results indicate that in elderly persons with cataract sleep is impaired, and that 1 month after cataract extraction improved sleep may be experienced.

Sleepiness and sleep in elderly subjects with hearing complaints.
The aim of this study was to evaluate the relation of hearing complaints to daytime sleepiness and sleep in a group of elderly men and women. A questionnaire survey was undertaken among 10,216 elderly subjects in northern Sweden. The mean (+/- S.D.) ages of the men and women were 73.0 +/- 6.0 and 72.6 +/- 6.7 years, respectively. Poor hearing was reported by 43.1% of the men and 22.8% of the women. The relative numbers with hearing complaints increased with age. Daytime sleepiness (DS) was reported by 32.9% of the men and 23.2% of the women. In a multiple logistic regression analysis significant independent correlates of daytime sleepiness in men were: hearing, good versus poor (odds ratio [OR] 1.5; confidence interval [CI] 1.2-1.8), health, good versus poor (3.3; 2.6-4.4), sleep, good versus poor (2.1; 1.6-2.8) and age, > or =80 years versus < 70 years (1.5; 1.1-2.1). The corresponding correlates in women were: hearing (1.4; 1.1-1.8), health (4.3; 3.4-5.4), sleep (2.2; 1.6-2.8) and age (1.6; 1.3-2.2). Thus, poor hearing was associated with increased daytime sleepiness independently of health, sleep status and age. Also subjects with hearing complaints more often slept poorly, woke up more often and had more difficulty in falling asleep after waking.

Sleepiness and sleep in elderly persons with tinnitus.
The aim of this study was to evaluate the relation of tinnitus to sleep and daytime sleepiness (DS) in a group of elderly men and women. A questionnaire survey was undertaken among 10,216 elderly subjects in northern Sweden. The mean (+/-s.d.) ages of the men and women were 73.0+/-6.0 and 72.6+/-6.7 years, respectively. Tinnitus was reported by 14.9% of the men and 12.0% of the women. The relative number with tinnitus was not related to age in men, but increased with age in women. Poor sleep was reported by 14.4% of the men and 27.9% of the women. Among subjects with tinnitus poor sleep and frequent waking were more common in both sexes, while difficulties in falling asleep after awakening at night were reported more often by women. DS was more common in subjects with tinnitus and the frequency was even more increased in those with both tinnitus and poor sleep. There was no further increase in DS in men and women on sleep medication. Thus, DS in elderly persons with tinnitus may due both to tiring effect of the annoying sound itself but also the negative effect by tinnitus on sleep.

Sleep, health and visual impairment in the elderly.
This study was undertaken in order to analyse the relationship between visual impairment and sleep in an elderly population. All 10?216 members of the pensioners' association in two Swedish counties were asked to participate in a questionnaire survey. The questionnaire included questions on civil status, the general state of health, the occurrence of somatic diseases and symptoms, sleep, medication and vision. 6143 evaluable questionnaires were received, of which 39.5% were from men. The mean (s.d.) ages of the male and female participants were 73.0 (6.0) and 72.6 (6.7) years, respectively. Visual impairment was reported by 20.9% of the men and 32.9% of the women. The proportion of visual impairment increased with age and was more common in women in each age group. Poor sleep occurred in 14.4% of the men and 27.9% of the women. Among subjects with visual impairment, poor sleep, frequent awakenings and difficulties to fall asleep after awakening at night were all more common in both men and women. In a multiple logistic regression analysis, significant independent correlates of poor night's sleep among the men were: visual impairment (odds ratio (OR) 1.3 95%, confidence interval (CI) 1.0-1.8) and poor health (OR 2.2, CI 1.6-3.0). Age, circulatory organ disease and diabetes were deleted by the logistic model. The significant independent correlates in women were: visual impairment (OR 1.6, CI 1.3-2.0) poor health (OR 2.6, CI 2.1-3.3) and circulatory organ diseases (OR 1.5 CI, 1.2-1.8). Age and diabetes were deleted by the logistic model. The results suggest that visual impairment could be an underestimated cause of sleep deterioration in the elderly.
