Evidence suggests that childhood physical
activity may play a role in the etiology and prevention of adult chronic
diseases. Because researchers must often depend on self-recalled physical
activity data many years after the exposure, it is important to understand
factors which may influence adult recall of childhood physical activity. This
study evaluated the influence of adult characteristics on reported
childhood physical activity and the association between adult physical
activity and self-recalled childhood physical activity.
48,066
post-menopausal women from the Women’s Health Initiative Observational Study
reported their physical activity level during ages 5-9, 10-14, and 15-19. And childhood physical activity recalled at ages 5 - 9, 10 - 14, and
15 - 19 was categorized into three levels: physically inactive (0 - 1
days/week), low physical activity (2 - 3 days/week), and high physical activity
(≥ 4 days/ week).
In this cohort,
over 65% of the population reported the same category of physical activity over
the three childhood age groups. While higher levels of childhood physical activity
were significantly associated with higher adult physical activity, this
association varied by race/ethnicity, education, smoking, body mass index,
history of diabetes or cardiovascular disease, social support and physical
functional status. Women who were consistently highly active reported
adult physical activity levels that were 2.82 MET-hr/week (95% C.I. = 2.43,
3.20) higher compared to women who were always physically inactive during
childhood.
In conclusion, Lifelong
physical activity patterns, including those during childhood, may play an
important role in the etiology of chronic disease and promotion of childhood
activity should be encouraged. In addition, it is important for researchers to
understand the influence of adult characteristics on reported childhood
physical activity.
