Abstract

Abstract

Objective To explore the influence of transportation mode, working status, and leisure time activity on overweight and obesity among young adults aged 20 to 39 in Guangxi, so as to provide a reference for improving the physical fitness level of the whole population. Methods A randomized whole-group sample of young adults aged 20-39 years from institutions in cities of Guangxi was conducted, with a total of 7 534 cases. The data were divided into 20- < 30 and 30-39 ages groups, and a random forest classification model were constructed after over-sampling a random forest classification model. Results According to the decline of the Gini index, we ranked the importance of the variables. The main influencing factors of overweight and obesity for young people aged 20- < 30 were the time spent riding motorcycles, electric bicycles, reading and using computers, the time spent watching TV and listening to the radio, mainly sitting at a desk, and light housework. As for 30-39 age group, the influencing factors of overweight and obesity were, in order, the length of time riding a motorcycle or electric vehicle; the length of watching TV and listening to the radio; the length of reading and using the computer; the length of light housework; the length of sitting mainly at the desk. Conclusions People should try to shorten the duration of sedentary behavior. In a short distance, try to choose cycling and walking, avoid sedentary work style and leisure activities, and increase scientific and regular physical exercise will be good choices.
