To understand the impact and pathways of lifestyle behaviors on physiological sub-health of medical students, and to provide a basis for health management and health education in universities.
Under the use of stratified whole cluster random sampling method, 3 100 medical students from a medical university were selected as the study subjects, general situation questionnaire, lifestyle factor questionnaire and Sub-Health Measurement Scale Version 1.0 (SHMS V1.0) were used for questionnaire survey. Chi-square test, exploratory factor analysis and structural equation model were used for statistical analysis and path construction.
The total detection rate of medical students’ sub-health status was 62.2%. There were significant differences in the distribution of drinking (χ2=12.245,P<0.001), activity(Frequency of exercise(χ2=46.115, P<0.001);Frequency of activities between classes(χ2=7.179,P=0.028);Leisure promotes health(χ2=60.789,P<0.001)), dietary habits (Frequency of takeout orders(χ2=8.912, P=0.012);Frequency of consumption of sugar-sweetened beverages(χ2=23.437,P<0.001);Bad eating habits(χ2=82.863,P<0.001))and mobile phone and computer usage(Time spent on mobile phones and computers(χ2=12.350, P=0.002); Short video viewing time(χ2=9.291,P=0.026)) among medical students with different physiological health states. The direct effect of activity on physiological sub-health of medical students was 0.26(95% CI:0.137-0.366). The direct effect of dietary habits on physiological sub-health of medical students was -0.171 (95% CI:-0.233--0.035), and the indirect effect was -0.04(95% CI:-0.085--0.015). The indirect effect of mobile phone and computer usage on physiological sub-health of medical students was -0.043 (95% CI: -0.087--0.017).
The overall detection rate of sub-health status among medical students is relatively high. Physical activity is a significant influencing factor in the physiological sub-health status of medical students and serves as a mediator between dietary habits and mobile phone and computer usage with respect to the physiological sub-health status of medical students.
