Key result
Age 20 to 40 linked to ~2.5-fold higher risk of hypertension among healthy blood donors.
Why the study?
Hypertension is a major public health concern, especially in resource-limited countries, prompting investigation into characteristics and risk factors related to high blood pressure among healthy blood donors in Luanda, Angola.
Cohort (n=343)
Yes
High blood pressure is present in 7.3% of healthy blood donors in Luanda, Angola, highlighting the need for cardiovascular disease screening and control strategies in this population.
Answers are grounded in this paper and cite their sources.
May support local hypertension screening in young Angolan adults; leaves open generalizability beyond this donor cohort.
Background and Aims Hypertension is a public health concern, mainly in resource‐limited countries. We investigated the characteristics and risk factors related to high blood pressure in healthy blood donors from, Luanda, the capital city of Angola. Methods This was a retrospective study that included 343 healthy donors from December 2019 to September 2020. Results The mean age was 32 ± 9 years. Men represented 93% of the population. Mean systolic blood pressure (SBP) was 131 ± 12.3 mmHg (ranging from 100 to 160 mmHg) and diastolic blood pressure (DBP) was 80.1 ± 9.72 mmHg (from 56.0 to 100 mmHg). DBP was related to age and gender ( p < 0.05). About 7.3% of the donors had high‐pressure (>140/90 mmHg). Age between 20 and 40 years (odds ratio [OR]: 2.52, p = 0.043), women (OR: 1.87, p = 0.548), nonurbanized areas (OR: 0.39, p = 0.067), high educational level (OR: 0.76, p = 0.637), employed (OR: 0.49, p = 0.491), voluntary donors (OR: 0.87, p = 0.799), blood group B (OR: 2.06, p = 0.346), and Rh‐ (OR: 0.26, p = 0.104), were potentially related with high‐pressure. The high‐pressure cases increased from December 2019 (4%) to September 2020 (28%) ( p = 0.019). Conclusion We showed high pressure among the healthy blood donors population. Demographic characteristics, ABO/Rh blood group, and year period are features that should be considered in cardiovascular disease control strategies. Biological and nonbiological features related to blood pressure changes should be considered for further studies in the Angolan population.

Sebastião et al. (2023) conducted a cohort in High blood pressure (n=343). Age 20-40 years vs. Other age groups was evaluated on High blood pressure (>140/90 mmHg) (OR 2.52, 95% CI 1.03-6.15, p=0.043). Among healthy blood donors in Luanda, Angola, 7.3% had high blood pressure, with individuals aged 20 to 40 years having a higher risk of presenting with high blood pressure.
