Socio-spatial disparities of obesity among adults in the urban setting of Ouagadougou, Burkina Faso.
OBJECTIVE
To document the prevalence and the socio-spatial variations of obesity and to identify individual and household characteristics, lifestyles and dietary practices contributing to obesity and its socio-spatial distribution.


METHODS
Population-based cross-sectional survey. We selected 1,570 households from four strata characterised as unstructured and low building-density (ULBD), unstructured and high building-density (UHBD), structured and low building-density (SLBD) and structured and high building-density (SHBD) areas. Structured areas are those that were allotted by the township authority (cadastral services), with public services; unstructured areas refer to those developed with no cadastral organisation.


METHODS
Ouagadougou, the capital city of Burkina Faso.


METHODS
BMI was calculated in 2022 adults aged 35 years and above who were classified as obese when their BMI was >or=30 kg/m2. Obesity was investigated in relation to household and individual characteristics, lifestyles and dietary practices; adjusted odds ratios with 95 % confidence intervals were derived from a logistic regression model.


RESULTS
The overall prevalence of obesity was 14.7 % (males 5.5 % and females 21.9 %). Age, gender, household equipment index, usual transport with motor vehicles and micronutrient-rich food consumption were associated with obesity. After adjustment for these factors, obesity remained associated with the area of residence: residents from SHBD areas were more likely to be obese than those from ULBD areas (OR = 1.41; 95 % CI 2.59,4.76).


CONCLUSIONS
Obesity in Ouagadougou is a preoccupant problem that calls for more consideration. Thorough investigation is needed to assess the environmental factors that contribute to the socio-spatial disparity of obesity.
