This figure shows median sitting time in minutes per day. Botswana and Ghana recorded higher median sitting time than Nigeria and Tanzania.

NRF_PA_MH_Figure_S3.png (Sitting time and depression risk)

This figure shows the simple slope of the relationship between COVID-19-like symptom burden and depressive symptoms across low, moderate, and high sitting-time groups. The slope is strongest at high sitting time, especially in Ghana, indicating that prolonged sitting may intensify the mental health burden associated with COVID-19-like symptoms.
