Trading-Off Transit and Non-Transit Physical Activity among Older People: Evidence from Longitudinal Accelerometer Data of a Natural Experiment Study

This article reports on a study that used a new metro line in Hong Kong (with eight new stations) as a natural before-after study to look at transit-related and non-transit-related physical activity in older people (n = 104; age greater than 65 years). The study used longitudinal accelerometer data and difference-in-difference analysis. The authors found that new metro stations have trade-off effects between transit and non-transit PA. Specifically, after the opening of new metro stations, transit-related PA increased by 12 min per day on average, but non-transit-related PA decreased by 18 min per day. There was also a significant increase of 4.22% in the proportion of time spent on transit-related PA in the treatment group after the opening of new metro stations. The study included built environment characteristics, such as population density, the number of bus stops, and points of interest. Participant-level individual variables included age, gender, monthly income, education level, and chronic disease (yes or no). The authors conclude with a discussion of the potential trade-off effects of public transit interventions and related implications for health aging.
