  1. Fulltext. Do elderly women have more physical disability than men do ?

    Article - En anglais


    This study investigated whether the commonly observed higher prevalence of physical disability among women is due to higher incidence rates or to other factors such as selective mortality or poor recovery.

    Methods included observed measures of prevalent lower body physical disability and potential risk factors at baseline (1989-1991) and 4-year follow-up of 2,025 community-dwelling adults aged 55 years and older in Marin County, California.

    Incidence, recovery, and mortality rates were determined at the follow-up examination.

    Results indicated that women had higher age-specific and age-adjusted prevalence rates at both examinations (odds ratios=1.66 and 1.60, p<0.001) but that incidence rates were not significantly different (odds ratio=1.12,95% confidence interval : 0.77,1.64).

    In the classic formulation, prevalence=incidence x duration, the higher prevalence rates in women could not be due to a higher incidence rate, but could be explained by longer duration due to lower recovery and mortality rates in women.

    Incident physical disability was predicted by prevalent chronic illnesses, poor vision, obesity, physical inactivity, poor memory, fewer social activities, and higher depression scores, but not by sex.

    Prevention efforts should concentrate on reducing known risk factors in both men and women and on promoting higher recovery rates among women.
