The effect of hormone replacement on physical performance in community-dwelling elderly women.

PURPOSE: Our aim was to determine the effect of hormone replacement on physical performance measures, functional ability, physical activity, falls, and cognitive function in elderly women. SUBJECTS AND METHODS: Following a 3-month, open-label, run-in phase, we randomized 373 community-dwelling women aged 65 years and older to receive conjugated equine estrogen 0.625 mg/day plus or minus medroxyprogesterone 2.5 mg/day vs placebo for 3 years in a double-blind fashion. We assessed time to rise from a chair, timed walking, balance, Instrumental Activities of Daily Living, Physical Activity Scale of the Elderly, Folstein Mini-Mental State Examination, and falls.
RESULTS: Over 3 years, except for balance scores, performance measures declined significantly (all P<.05). There were no significant mean differences between women on hormone replacement versus placebo for rising time (0.1, -0.5 to 0.7 seconds [mean, 95% confidence interval]), walking normal (0.0, -0.4 to 0.4 seconds), and walking fast (0.2, -0.1 to 0.6 seconds). There were no significant mean differences between the two groups for the Instrumental Activities of Daily Living (0.1, -0.1 to 0.3 points), Physical Activity Scale of the Elderly (-3, -15 to 8 points), Folstein Mini-Mental State Examination (-0.1, -0.3 to 0.3 points), or the proportion of participants reporting falls (-1, -11 to 9%).
CONCLUSION: In elderly women, hormone replacement had no statistically significant effect on cognition or balance, nor did it prevent the age-related decline in physical measures of mobility, ability to rise from a chair, self-reported activities of daily living, physical activity scores, or falls.
