1A higher MHI score indicates better mental health; thus, a negative beta indicates a negative association between sitting time and mental health; 2Adjusted for gender, age, education, household composition, perceived health, physical activity, smoking, and alcohol consumption; 3additionally adjusted for BMI; 4when added to this model: 𝑃 ≤ 0 . 0 5 for a positive interaction term; 5when added to this model: 𝑃 ≤ 0 . 0 5 for a negative interaction term.
