Abstract
Background: Sex differences in the longitudinal relationship between dynapenic abdominal obesity, i.e., impairment in muscle strength and high waist circumference, and activities of daily living disability have not been investigated to date. Therefore, we aimed to examine sex differences in the longitudinal association between dynapenic abdominal obesity at baseline
and new onset activities of daily living disability during a four-year follow-up period among Irish adults aged ≥50 years.
Methods: Data from Wave 1 (2009-2011) and Wave 3 (2014-2015) of the Irish Longitudinal Study on Ageing survey were analyzed. Dynapenia was defined as handgrip strength of circumference of >88 cm for women and >102 cm for men. Dynapenic abdominal obesity was defined as having both dynapenia and abdominal obesity. Disability was defined as having difficulty with at least one of six types of activities of daily living (dressing, walking, bathing, eating, getting in or out of bed, using the toilet). Multivariable logistic regression was conducted to assess associations.
Results: Data on 4,471 individuals aged ≥50 years free of disability at baseline were analyzed [mean (SD) age 62.3 (8.6) years; 48.3% males]. In the overall sample, compared to no dynapenia and no abdominal obesity, dynapenic abdominal obesity was associated with 2.15 (95%CI=1.17-3.93) times higher odds for incident disability at 4-year follow-up. This association was significant among males (OR=3.78; 95%CI=1.70-8.38) but not among females (OR=1.34; 95%CI=0.60-2.98).
Conclusions: Interventions to prevent or address DAO may aid in the prevention of disability especially among men.
