title: [Determinants of insomnia in relatively healthy elderly. A literature review].
abstract: A review is presented based on the findings resulting from interview and questionnaire research concerning factors that determine insomnia in relatively healthy elderly. The investigated factors include modes of living, sleep wishes and personality aspects. During the period 1988-1997 18 published reports were found. Based on the findings it is difficult to claim that elderly persons with insomnia are characterized by inappropriate modes of living. There were, however, some (inconsistent) indications that tea consumption, smoking and lack of exercise predicted insomnia. There were also scarce indications for less realistic sleep expectations in bad than in good sleepers. More bad sleepers perceived their sleep as uncontrollable and unpredictable than than good sleepers. Bad sleepers had significantly higher scores for anxiety, neuroticism and depression than good sleepers. Anxiety as well as depression correlated positively with insomnia and negatively with sleep duration. Depression, anxiety or neuroticism often were better predictors of insomnia than health indicators such as perceived health and number of prescribed drugs. The findings suggest that insomnia in relatively healthy elderly is more tightly associated with psychological factors than with modes of living or health indicators. This has some consequences for therapy. In addition to advice concerning modes of living and sleep hygiene, one has to be alert for the possible presence of depression or anxiety. In that case depression or anxiety has to be treated, pharmacologically or nonpharmacologically.
