Physical activity may attenuate psychological distress associated with different types of sedentary behaviors: a cross-sectional study of 10972 Chinese students.

Abstract

The aim of the study was to investigate independent and joint associations of physical activity and sedentary behavior with psychological distress. In this cross-sectional study, all participants underwent a physical examination and questionnaire survey, including physical activity, sedentary behavior, and psychological distress. The rank-sum test was used to compare the distribution of psychological distress status among students with different characteristics, physical activity levels, and sedentary time. Logistic regression models were used to analyze the independent and joint association between physical activity, sedentary behavior, and psychological distress, stratified by age. The results of the rank sum test and logistic regression showed that students with more sedentary behavior and less physical activity were associated with higher psychological distress generally, but physical activity may attenuate the psychological distress relevant to non-screen-based sedentary behavior on weekdays in middle and high school students and screen-based sedentary behavior on weekends in all participants.
