This study aimed to explore factors associated with Physical Activity (PA) in Jordanian older people. Global Physical Activity Questionnaire was used to measure PA in 120 adults aged ≥ 60 years. Physical and psychosocial factors related to PA were measured including gait and balance, cognition, health-related quality of life, self-reported health, fear of falling and sociodemographic factors. Multiple linear regression analysis showed that longer sedentary time (Beta = −0.23, p = .009) and female gender (Beta = −0.36, p < .001) predicted lower PA. Use of walking aids (Beta = 0.21, p = .02) and poorer perceived general health (Beta = −0.25, p = .01) predicted longer sedentary time. Only small variance (adjusted R2 = 0.25 for PA and 0.22 for sedentary time, p < .001) was explained by the variables. Larger scale studies should explore cultural and environmental factors that could explain PA in this population.
