Association of Perceived Environment and Physical Activity in Older Adults After the Great East Japan Earthquake.

The aim of this study was to examine the association between perceived environment and physical activity among older adults in Fukushima Prefecture after the 2011 Great East Japan Earthquake and the impact of evacuation. Questionnaires were distributed to individuals aged 65 years and older from October to November 2018. Perceived environment was assessed using a five-item questionnaire on home fitness equipment, access to facilities, neighborhood safety, enjoyable scenery, and frequency of observing others exercising. Physical activity, assessed via the Physical Activity Questionnaire for Elderly Japanese, was segregated into levels based on the median score. Data from 249 participants (74.2 ± 6.9 years) were analyzed. A logistic regression analysis found that the unenjoyable Scenery × Residing in restoration public housing interaction (odds ratio = 3.87, 95% confidence interval = [1.20, 12.46]) was significant. The association between enjoyable scenery and physical activity varied according to whether the participants had experienced evacuation or not.
