Key result
Bantu ethnicity and urban residency were significantly associated with higher hypertension prevalence, which was 18.0% in urban Bantus compared to 4.1% in traditional Pygmies.
Why the study?
The impact of urbanization and living conditions on the prevalence of hypertension in the Cameroonian population is poorly known.
Are Bantu ethnicity and urban residency associated with a higher prevalence of hypertension compared to Pygmy ethnicity and rural residency in Southern Cameroon?
Cross-Sectional (n=406)
Are Bantu ethnicity and urban residency associated with a higher prevalence of hypertension compared to Pygmy ethnicity and rural residency in Southern Cameroon?
Absolute Event Rate: 18% vs 4.1%
Urbanization and Bantu ethnicity are significantly associated with higher blood pressure and hypertension prevalence in Southern Cameroon.
INTRODUCTION: The impact of urbanization and living conditions on the prevalence of hypertension in the Cameroonian population is poorly known. AIM: To evaluate the prevalence and determinants of blood pressure (BP) in adult Pygmies and Bantus living in urban and rural areas of Southern Cameroon. PARTICIPANTS AND METHODS: This was a cross-sectional comparative study of 406 adults (96 urban Bantus, 100 urban Pygmies, 111 rural Bantus and 99 tropical rainforest Pygmies with a traditional Pygmies way of life), recruited in Southern Cameroon (mean age 42 ± 17 years; 56.7% women). Sociodemographic, anthropometric and BP parameters were collected. Hypertension was defined as BP at least 140/90 mmHg and/or use of BP-lowering drug(s). RESULTS: The age-standardized prevalence of hypertension in urban Bantus, rural Bantus, urban Pygmies and traditional Pygmies was 18.0, 13.5, 9.3 and 4.1%, respectively. Mean SBP and DBP differed significantly according to Bantu vs. Pygmy ethnicity, and urban vs. rural residency. After multiple adjustments, mean arterial pressure was significantly associated with age, BMI, Bantu ancestry and urban residency. CONCLUSION: Bantu ethnicity and urban residency are significantly associated with high-BP among people from Southern Cameroon.

Lele et al. (2020) conducted a cross-sectional in Hypertension (n=406). Urban residency and Bantu ethnicity vs. Rural residency and Pygmy ethnicity was evaluated on Prevalence of hypertension. Bantu ethnicity and urban residency were significantly associated with higher hypertension prevalence, which was 18.0% in urban Bantus compared to 4.1% in traditional Pygmies.
