Energy balance

The association of sitting time with the composite outcome is stronger in low-income and lower-middle-income countries (HR, 1.29; 95% CI, 1.16-1.44) compared to high-income and upper-middle-income countries (HR, 1.08; 95% CI, 0.98-1.19).

Public health strategies should focus on reducing sitting time, especially in low-income countries.

When stratified by country income levels, the association of sitting time with the composite outcome was stronger in low-income and lower-middle-income countries (≥8 hours per day: HR, 1.29; 95% CI, 1.16-1.44) compared with high-income and upper-middle-income countries (HR, 1.08; 95% CI, 0.98-1.19; P for interaction = .02).
