| Annotation | The present study hypothesised that simple everyday physical activity (EPA) would decline with advancing age, that women would have a more favourable EPA profile than would men, and that EPA would have a survival benefit. This Study of Everyday Physical Activity was part of the Aging in Manitoba (AIM) Longitudinal Project. 198 community-dwelling participants aged 80-98 wore mechanical actigraphs in order for EPA to be assessed. Individuals were classified as active, inactive or sedentary based on their level of EPA exhibited over a substantial part of the day. Mean EPA scores decreased with advancing age and, in contrast to men, women in their early 80s appeared to be protected from declining EPA. This partially supported the hypothesis that women would have a more favourable EPA profile. Most important is that EPA scores predicted mortality. Moreover, when compared with their less sedentary counterparts, sedentary adults were more than three times as likely to be deceased 2 years later. Researchers need to conduct new trials to determine whether or how physical activity is associated with mortality. (RH). |
