ABSTRACT
OBJECTIVE:
To explore the relationship between long-term physical activity (PA) participation and falls.METHODS:
Participants in the Australian Longitudinal Study of Women's Health born 1946-1951 self-reported amounts of PA every 3 years since 1998 (mean age 54 years, n=11 796). Latent class analysis described profiles of self-reported PA participation over 18 years. Associations between patterns of PA participation and self-reported falls measured in 2019 were examined using multinomial logistic regression adjusted for directed-acyclic graph-informed potential confounders, with the highly active group as the reference category.RESULTS:
Women were grouped into five PA participation profiles. Compared with consistently highly active patterns (maintaining ≥300 min/week, 22%), consistently lower levels of PA<100 min/week (18%), consistently some PA<150 min/week (18%) and decreasing PA but maintaining≥150 min/week (n=3540, 30%) had higher odds of non-injurious falls (odds Ratiolower level (OR) 1.59, 95% CI 1.29 to 1.97; ORsome PA 1.27, 95% CI 1.04 to 1.55; ORdecreasing activity1.29, 95% CI 1.02 to 1.63) and injurious falls (ORlow level 1.32, 95% CI 1.06 to 1.64; ORsome PA 1.27, 95% CI 1.04 to 1.54; ORdecreasing activity 1.47, 95% CI 1.18 to 1.83). No association was found between increasing PA (≥150 min/week, 11%) for non-injurious (OR 1.07, 95% CI 0.89 to 1.29) and injurious falls (OR 1.07, 95% CI 0.90 to 1.29). After adjusting for potential confounders, consistently lower levels of PA remained associated with increased non-injurious falls odds (OR1998 survey 1.40, 95% CI 1.11 to 1.77; OR2016 survey 1.35, 95% CI 1.07 to 1.71).CONCLUSION:
The increased odds of falls among women with consistently lower levels of PA over 18 years supports ongoing participation of 150+ min/week of PA.Key words
