  1. Incidence and remission of Insomnia among elderly adults in a biracial cohort.

    Article - En anglais

    Objectives 

    To determine the incidence and remission rates of insomnia in older adults according to race and associated risk factors in a three-year longitudinal study.

    Methods 

    2,971 men and women, aged 65 years and older, completed questionnaires administered by trained interviewers at baseline and three years later.

    Data conceming difficulty falling asleep or early moming arousal (insomnia), along with self-reports of physical disability, respiratory symptoms, depressive symptomatology, perceived health status, and use of prescribed sedative medication, were collected and analyzed.

    Results 

    Overall, 15% of the participants without symptoms of insomnia at baseline reported chronic difficulty falling asleep or early morning arousal three years later in follow-up interviews.

    African-American women had a significantly (p<0.01) higher incidence of insomnia (19%) compared with African-American men (12%) or with white men and women (both 14%). Men were more likely than women to no longer report symptoms at follow-up (64% vs 42% ; p<0.01).

    For both races, the presence of depressed mood was a risk factor for the incidence of insomnia, and the absence of depressed mood was a predictor of remission.

    Conclusions 

    Insomnia occurs more frequently in African-American women than in African-American men or than in white men or women.

    Regardless of race, women are less likely than men to resolve their insomnia. (...)
