of 57 Consecutively Diagnosed Cases
Sleep 2005; 28(8): 945-952

•        The onset of non–24-hour sleep-wake syndrome had occurred
during the teenage years in 63%
•        The mean sleep length of the patients was 9.3 ± 1.3 hours, and
44% of them had a sleep length of between 9 and 10 hours.
•        Psychiatric disorders had preceded the onset of non–24-hour

the Community
Sleep 2005; 28(8): 981-989

•        A total of 7010 randomly selected households were contacted
in  metropolitan area of Paris, France.
•        The median nighttime sleep duration was 7 hours without
significant difference between the age groups.
•        Factors positively associated with less sleep (4 hours 30
minutes or less) of nighttime sleep duration were obesity, poor health,
insomnia, and insomnia accompanied by daytime sleepiness and
cognitive impairment.
•        Long sleep (9 hours 30 minutes or more) was associated with
organic disease, lack of physical exercise, and lower education.
•        A daytime sleep duration of 1 hour or more was associated with
being a man, cognitive impairment, high blood pressure, obesity, and
insomnia.
•        Long sleep latency (80 minutes) was associated with anxiety,
lower education, poor health, insomnia without excessive daytime
sleepiness, and obstructive sleep apnea syndrome.
•        Obesity and loss of autonomy in activities of daily living was
associated with both early (9 PM or earlier) and late bedtime (1 AM or

Menopause Related Sleep Disorders
Journal of Clinical Sleep Medicine 1(3); 291-300; 2005

This is good review of Sleep Disorders associated with menopause.  
Common disorders include insomnia/depression, sleep disordered
breathing, and fibromyalgia.  Menopause may exacerbate other pre-
existing sleep disorders including RLS and circadian disorders.
Insomnia may be seen in women with vasomotor symptoms.  This
may require hormonal therapy.  SDB increases markedly at
menopause due to weight gain and hormonal changes.
