Research Impact: Muscular strength predicts cardiometabolic disease risk, physical disabilities, mortality, and mental health across aging populations; however, associations between grip strength and Generalized Anxiety Disorder (GAD) remain unstudied. This study investigated associations between grip strength and prevalent and incident GAD among 3,952 community dwelling adults aged ≥50 years. Grip strength was significantly, inversely associated with prevalent GAD at baseline, and non-significantly, inversely associated with GAD at two-year follow-up. As resistance exercise improves strength and functional limitations, and reduces anxiety symptoms in older adults (Gordon et al., 2017), these findings further support that resistance exercise may both improve strength and protect against GAD among older adults.
