Purpose: The aim of this study was to compare the predictors of physical activity between urban and rural dwelling Korean older adults. Methods: This study was a cross-sectional descriptive survey. A self-report questionnaire or face to face interviews were used to collect data from 336 older adults (urban: 129, rural: 207) who visited public health centers or welfare centers in 2008. Results: About half of the participants (urban: 50.4%, rural: 47.3%) were classified as the minimally active group. Cognitive function (odds ratio [OR]=1.106, p=.004) and loneliness (OR=0.965, p=.044) were predicting factors for physical activity in rural elderly. Age (OR=0.326, p=.037), gender (OR=2.841, p=.021) and depression (OR= 0.799, p<.001) were significant factors predicting physical activity in urban elders. Conclusion: These findings provide information that is relevant in designing interventions to enhance physical activity in older adults. There is a need to develop effective mutifaceted physical activity interventions that include reducing psychological barriers such as depression, loneliness.
