  • Gender & Racial effect on elderly slowing

    Dear netters:

    Let me put some points to stir the discussion on the slower
    walking pace
    of the elderly.

    In a cross-sectional pilot study, we found that Caucasian
    healthy women
    did not significantly slow down their walking pace until very old
    (almost up to
    age 70 years, n=40); Caucasian men, 65 years (n=49); Asian men, 55
    years
    (n=47); Asian women, 45 years (n=80). The results might not be perfect
    owing to insufficient number of Caucasian women subjects. If this trend
    is
    true, will the explanations of elderly slowing become different?

    Provided that "joint stiffness" mentioned earlier in this list
    accounted for
    slower walking pace of the elderly, why do the Asian, often reported
    with less
    incidence of gonarthrosis or coxarthrosis than the Caucasian, slow down
    the
    walking path ealier in their lives than the Caucasian? On the other
    hand,
    Asian people often have significantly lower bone density.

    Slowing down, from my point of view, is advantageous to
    gonarthrosis
    prevention. I will be very grateful if anyone of you are interested in
    replying
    to me about following questions:

    1. Are you Caucasian or Asian ?
    2. Do you walk faster than your wife/husband/partner? What is your age
    and
    her/his age?
    3. If you are younger than 45 years, does your father walk slower than
    your
    mother? How old are they?

    It is perhaps the first large survey in this list. I will be
    very happy to
    summarize all the replies and post it as soon as possible. Please do
    take some
    time to answer it, because it may be very helpful for disease
    prevention.

    Thank you very much in advance!
