Methods: Data from two consecutive waves of the Irish Longitudinal Study on Ageing (TILDA) survey were analyzed. Dynapenia was defined as handgrip strength of 88 cm for women and >102 cm for men. DAO was assessed at Wave 1 (2009-2011) and was defined as having both dynapenia and abdominal obesity. Falls occurring between Wave 1 and Wave 2 (2012-2013) were self-reported. Multivariable logistic regression analysis was conducted.
Results: Data on 5275 individuals aged ≥50 years were analyzed [mean (SD) age 63.2 (8.9) years; 48.8% males]. After adjustment for potential confounders, compared to no dynapenia and no abdominal obesity at baseline, DAO was significantly associated with 1.47 (95%CI=1.14-1.89) times higher odds for falls at 2-year follow-up. Dynapenia alone (OR=1.08; 95%CI=0.84-1.40) and abdominal obesity alone (OR=1.09; 95%CI=0.91-1.29) were not significantly associated with falls at follow-up.
Conclusions: DAO increased risk for falls among middle-aged and older adults in Ireland. Interventions to prevent or reverse DAO may be beneficial for fall reduction.
