    Dear editor
    The recent study published by Runqi et al (1) on the prevalence and influencing factors of physical activity and sedentary behavior in the rural population in China: the Henan Rural Cohort Study found that lack of physical activity and sedentary in rural China contribute to increasing the incidence of disease, especially among the elderly and those who drink alcohol. (1) I commend the authors for their study but also wish to point out the importance of socioecological determinants of physical activity, particularly climate change.

    A study in the United States found that cold and hot weather, strong winds, and days of rain all forces people to spend more time indoors, all of which can reduce physical activities. (2, 3) A study in New York showed that people’s cycling time and distance decreased with increasing temperature at temperatures above 26 to 28 degrees Celsius. (4) Climate change significantly affects physical activity in older people. (5) In addition, climate change has increased the incidence of heat-related diseases, infectious diseases, food security, and mental health problems among people in rural areas and disadvantaged social-economic groups. (6) Climate change is leading to more frequent, persistent and intense extreme weather, age, obesity, diabetes, and cardiovascular diseases are risk factors for fever-related disease. (7) Therefore, these high-risk populations may reduce physical activity and increase sedentary during summer....
