Association between sedentary behaviour, sleep duration, physical activity and mental health among teachers in China during COVID-19: a cross- sectional study

Integrated behavioural interventions (sedentary behaviour, sleep duration and physical activity) are potential targets for the prevention and intervention of negative emotions in teachers.
