Physical Impairments Disrupt the Association Between Physical Activity and Loneliness: A Longitudinal Study

Introduction:This study explores the association between physical activity (PA), loneliness and the presence of physical chronic impairments among single older adults.Methods:A longitudinal study (N = 575; mean age 76 ± 8 years) was conducted. The association between self-reported weekly minutes of moderate to vigorous PA (MVPA), loneliness and presence of physical impairments was assessed with multilevel analyses at baseline, 3 months and 6 months.Results:Improvements in MVPA were associated with decreases in loneliness (B = - 0.09; SE = 0.04; p = 0.020): this association became non-significant when including the presence of physical impairments in the analyses (p = 0.824), which in itself was positively associated with loneliness (B = 0.51; SE = 0.10; p <0.001).Discussion:Findings indicate that physical impairments have a larger influence on loneliness than the level of PA. Interventions targeting PA and loneliness should tailor specifically to physical impairments.
