Active travel, like walking or biking to school, can boost physical activity in children. But how well is it studied in China? A recent review looked at 16 studies on this topic. Most of the research is new, with 75% published between 2017 and 2023. This shows growing interest in the field.
However, the quality of the studies is a concern. Nearly all (93.8%) were cross-sectional, meaning they only looked at one point in time. This makes it hard to know if active travel causes better health or if healthier kids just walk more. Also, 87.5% of studies relied on self-reported data, which can be inaccurate. None used devices to track actual travel modes.
The studies mostly took place in cities (81.3%), leaving rural areas understudied. About half (56.3%) looked at what factors are linked to active travel, while 43.8% examined health outcomes. Only a quarter reported how common active travel is.
Because of these weaknesses, we can't be sure about the benefits of active travel for Chinese youth. The review calls for better studies that follow kids over time and use devices to measure travel. It also suggests policies to make walking and biking safer and more appealing.
In short, while active travel is a promising way to improve youth health, more rigorous research is needed to guide effective policies in China.
