[Prevalence of sleep disorders in the elderly]

This study was performed with senior citizens in Greater Metropolitan Guadalajara, Mexico, who live in private homes, alone, or with family. Of these, 58% of men and 76% of women showed at least one symptom of sleep disorder according to the Goldberg General Health Questionnaire, while 8.5% were positive for all survey items. According to DSM IV criteria, 33.3% could be considered "cases" of sleep disorder, and none were under any type of treatment at the time of the study. These possible cases were apparently associated with gender and educational level, but not with marital status or age. In addition, no strong association was detected with the presence of depression, established according to Brink's Geriatric Depression Scale. Given the large amount of "possible cases" found that had not been previously detected and were not in any type of ad hoc treatment, we recommend promoting updated educational courses on this topic for health professionals (mainly doctors and nurses) in such a way as to facilitate timely case detection and thus increase and improve the accessibility of mental health services for the elderly population, increasing health education activities for this age group, their caregivers, and the general population.
