Study on How Climate and Air Pollution Affect Physical Activity in Adults Aged 18 to 55 in Shenzhen and Shenyang, China

What this Trial Is About

Researchers are studying how climate and air pollution affect physical activity levels in adults living in two Chinese cities, Shenyang and Shenzhen. Physical inactivity is a major global health concern and can be influenced by environmental factors such as temperature and air quality. This study aims to compare how differences in climate and pollution in these cities impact physical activity and related health measures. The study will include 62 participants from each city who will wear devices to measure their physical activity and ambient temperature every two months over one year, totaling six assessment rounds. Alongside, local weather and air pollution data, including PM2.5 levels, will be collected over about two years. The two cities differ in climate, with Shenzhen having warmer, longer summers and Shenyang having colder winters and industrial pollution. Participants will be monitored for body composition and physical activity using accelerometers and temperature sensors. Researchers will assess physical activity levels every two months and track exposure to environmental temperature, humidity, and pollution. The primary outcome is physical activity level over one year. Secondary measures include temperature, humidity, sunshine duration, PM2.5, and detailed body composition metrics. This data will help understand how environmental factors influence physical activity behavior.
