Key result
Urbanization is linked to significantly higher cardiometabolic risk factors compared to rural residence.
Why the study?
Unplanned urbanization plays a key role in chronic disease growth, motivating an assessment of cardiometabolic risk factors and their association with urbanization conditions in Bobo-Dioulasso, Burkina Faso.
Does residence in more urbanized sub-spaces increase the occurrence of cardiometabolic risk factors compared to a rural-like sub-space in adults aged 35–59 years in Bobo-Dioulasso?

Unplanned urbanization and socioeconomic disparities in a secondary West African city are associated with high rates of hypertension (40.5%) and overweight/obesity (43.2%), affecting both affluent and low-income urban sub-spaces.
Background: Unplanned urbanization plays a key role in chronic disease growth. This population-based cross-sectional study assessed the occurrence of cardiometabolic risk factors in Bobo-Dioulasso and their association with urbanization conditions. Methods: Through spatial sampling, four Bobo-Dioulasso sub-spaces were selected for a population survey to measure the adult health status. Yéguéré, Dogona, Tounouma and Secteur 25 had very different urbanization conditions (position within the city; time of creation and healthcare structure access). The sample size was estimated at 1000 households (250 for each sub-space) in which one adult (35 to 59-year-old) was randomly selected. Finally, 860 adults were surveyed. Anthropometric, socioeconomic and clinical data were collected. Arterial blood pressure was measured and blood samples were collected to assess glycemia. Results: Weight, body mass index and waist circumference (mean values) and serum glycemia (83.4 mg/dL ± 4.62 mmol/L) were significantly higher in Tounouma, Dogona, and Secteur 25 than in Yéguéré; the poorest and most rural-like sub-space (p = 0.001). Overall, 43.2%, 40.5%, 5.3% and 60.9% of participants had overweight, hypertension, hyperglycemia and one or more cardiometabolic risk markers, respectively. Conclusions: Bobo-Dioulasso is unprepared to face this public health issue and urgent responses are needed to reduce the health risks associated with unplanned urbanization.

Zeba et al. (2017) conducted a cross-sectional in Cardiometabolic risk factors (overweight/obesity, abdominal obesity, hypertension, hyperglycemia) (n=860). More urbanized sub-spaces (Tounouma, Dogona, and Secteur 25) vs. Poorest and most rural-like sub-space (Yéguéré) was evaluated on Occurrence of cardiometabolic risk factors (overweight/obesity, abdominal obesity, hypertension, hyperglycemia, and ≥1 cardiometabolic risk marker) (p=0.001). Urbanization in Tounouma, Dogona, and Secteur 25 was associated with significantly higher BMI, waist circumference, and glycemia than rural-like Yéguéré (p=0.001), with 40.5% overall hypertension.
