Introduction: Population aged >60 years compose the age group that grows the most disproportionately. Despite several positive individual and social aspects an increase in the prevalence of chronic non-communicable diseases, including OA is observed. Hypothesis: Whether physical activity (PA) levels and number of chronic diseases are associated with handgrip strength (HGS), chair stand test (CST) results, and difficulties to dressing among older adults presenting with hip pain and diagnosed with hip osteoarthritis (OA). Methods: We analyzed Wave 5 of the Survey of Health, Ageing and Retirement in Europe. We analyzed two age groups of individuals diagnosed with hip OA: 60-79 and 80-100 year groups. Univariate and multivariate logistic models were constructed considering the poor performance cut-offs in the strength, functioning, and mobility tests as the dependent variables, and physical inactivity, number of chronic diseases, body mass index (BMI), gender and education as the exposure variables. Results: We included 2.088 participants (mean age 73.1±8.5 years). The majority (89.3%) reportedly had two or more chronic diseases, the most prevalent being hypertension. The participants were mostly overweight or obese (69.8%); however, two of three (75%) participants reported moderate-to-vigorous daily activity. Low levels of moderate-to-vigorous PA were significantly and independently associated with muscle weakness, dysfunctioning, and poor mobility in both age groups (p<0.05). Having five or more chronic diseases was significantly associated with disability in individuals with hip OA aged ≥60 years (p<0.05). Conclusions: Low PA levels and chronic conditions are significantly associated with reduced functioning in individuals aged ≥60 years with symptomatic hip OA, especially in the 80-100 year subgroup. These findings are important for stakeholders to maintain adequate PA levels in older individuals despite their hip OA diagnoses.
