Socio-spatial disparities of obesity among adults in the urban setting of Ouagadougou, Burkina Faso

Abstract

Objectives: 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. Design: Population-based cross-sectional survey. We selected 1570 households from four strata characterised as unstructured and low building-density (ULBD), unstructured and high building-density (UHBD), structured and low buildingdensity (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. Setting: Ouagadougou, the capital city of Burkina Faso. Subjects: BMI was calculated in 2022 adults aged 35 years and above who were classified as obese when their BMI was $30 kg/m 2 . 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 5 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.

The double burden of malnutrition and cardiometabolic risk widens the gender and socio-economic health gap: a study among adults in Burkina Faso (West Africa)

“…Women were at least four times more affected by overall obesity than men, which is in line with previous reports in Ouagadougou (52) and other African cities (8,42,(53)(54)(55) . Abdominal obesity, which is known to be more deleterious to health (56) than overall obesity, also prevails in women.…”

Gender differences in sociodemographic and behavioural factors associated with BMI in an adult population in rural Burkina Faso – an AWI-Gen sub-study

“…It is important to note that women with secondary school education had a BMI level that was higher than those with no formal education (7.42 95% CI: 5.42; 9.42). This trend has been reported in previous studies [23,25]. Furthermore, the SEM results demonstrate that education is the most important driver of BMI for women (Figure 1) with small indirect effects via SES [23,25].…”

Obesity and Metabolic Syndrome in a Burkina Faso Urban Area: Prevalence,Associated Factors and Comorbidities

“…Women were more often overweight or obese (p=0.000). This prevalence is higher than the previous 2004 rate (14.7% for obesity and 33% for both overweight and obesity), using a population-based cross-sectional survey reported in Ouagadougou [7,8] with also female predominance. Age, gender, household equipment index (residents from structured and high building-density areas are more likely to be obese than those from unstructured and low building-density areas), usual transport with motor vehicles and micronutrient-rich food consumption are the factors associated with obesity in Ouagadougou [7].…”

“…According to the last census of the National Institute of Statistics and Demographics of Burkina Faso (Institut National de la Statistique et de la Démographie du Burkina Faso) in 2009, a total of 1 029 584 individuals with at least 20 years old were living in the urban municipality of Ouagadougou [6]. One previous study performed in Ouagadougou in 2004, focused only on obesity, shown that this prevalence was about 14% [7]. According to forecasts, the urban municipality of Ouagadougou has an annual growth rate of 7.6%, and the population doubled at each decade [6].…”
