Background: Although the relationship between self-rated health (SRH) and physical and mental health is well
documented in developed countries, very few studies have analyzed this association in the developing world,
particularly in Africa. In this study, we examine the associations of SRH with measures of physical and mental health
(chronic diseases, functional limitations, and depression) among adults in Ouagadougou, Burkina Faso, and how
these associations vary by sex, age, and education level.
Methods: This study was based on 2195 individuals aged 15 years or older who participated in a cross-sectional
interviewer-administered health survey conducted in 2010 in areas of the Ouagadougou Health and Demographic
Surveillance System. Logistic regression models were used to analyze the associations of poor SRH with chronic diseases,
functional limitations, and depression, first in the whole sample and then stratified by sex, age, and education level.
Results: Poor SRH was strongly correlated with chronic diseases and functional limitations, but not with depression,
suggesting that in this context, physical health probably makes up most of people’s perceptions of their health status.
The effect of functional limitations on poor SRH increased with age, probably because the ability to circumvent or
compensate for a disability diminishes with age. The effect of functional limitations was also stronger among the least
educated, probably because physical integrity is more important for people who depend on it for their livelihood. In
contrast, the effect of chronic diseases appeared to decrease with age. No variation by sex was observed in the
associations of SRH with chronic diseases, functional limitations, or depression.
Conclusions: Our findings suggest that different subpopulations delineated by age and education level weight the
components of health differently in their self-rated health in Ouagadougou, Burkina Faso. In-depth studies are needed to
understand why and how these groups do so.
