Associations Between Time Spent in Green Areas and Physical Activity Among Late Middle-Aged Adults

Associations Between Time Spent in Green Areas and Physical Activity Among Late Middle-Aged Adults

Initiatives -
The main goal of this study is to reach an understanding where late middle-aged adults are mostly physically active in terms of location and in relation to greenness. Secondly, the influence of several individual characteristics, such as gender, working status, body mass index (BMI) and diploma as well as neighbourhood greenness has been studied with respect to PA and its association with greenness and location. Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

Data Collection Event
They were all visited at home and asked to wear a GPS device (Qstarz BT-Q1000X; Qstarz International, Taipei, Taiwan) and an accelerometer (Actigraph GT3X, GT3X+, or GT1M; ActiGraph, Fort Walton Beach, FL, USA), a valid and reliable tool for objectively measuring PA levels. The instruments were worn at waist height for a week.
