Sleep quality and hypertension in an indigenous African population: a cross-sectional investigation from the COMBAT-CVDs study.

Hypertension is a major risk factor for cardiovascular events worldwide, and little is known about its association with sleep quality (SQ) among Africans. We evaluated the association of SQ with hypertension among adults in Ibadan, Nigeria. In Ibadan and its suburbs, we identified 3635 participants in the door-to-door Community-based Investigation of the Risk Factors for Cardiovascular Diseases (COMBAT-CVDs) study.
