This study aimed to assess the prevalence, awareness, treatment, and control of hypertension in patients attending an outpatient clinic at a general hospital in Huambo, South Angola.A total of 265 subjects aged 18 years and older were included. Evaluation included complete interview and blood pressure measurement using a validated automatic device.The prevalence rates of hypertension and prehypertension were 38.5% (95% confidence interval [CI]: 32.83%-44.90%) and 30.20% (95% CI: 24.52%-36.22%), respectively. Hypertension was associated with age (>35 years; odds ratio [OR] = 10.09, 95% CI: 5.46-18.66, P < 0.01) and female gender (OR = 1.81, 95% CI: 1.08-3.05, P = 0.02). Among total hypertensive patients, 54.9% were aware of their diagnosis, 28.43% were in treatment, and 7.84% had controlled blood pressure. Lack of awareness was significantly higher in younger (age 37 years; OR = 3.28, 95% CI: 1.13-9.49, P = 0.02).This study revealed a high prevalence of hypertension, with low awareness, treatment, and control rates. Greater efforts are necessary to overcome these challenges.

Background. Peripheral arterial disease (PAD) is a common manifestation of atherosclerosis, whose prevalence is increasing worldwide, and is associated with all-cause mortality. However, no study has assessed this disease in Huambo. The aim of this study was to evaluate the prevalence of PAD in patients attending an outpatient clinic at a general hospital in Huambo, South Angola. Methods. A cross-sectional study, including 115 patients aged 40 years and older attending an outpatient service. The evaluation included a basic questionnaire for lifestyle and medical history and ankle-brachial index (ABI) measurement using hand-held Doppler. PAD was defined as an ABI 0.9 in either lower limb. Results. Of 115 patients, 62.60% were women with a median age of 52.5 (range of 40 to 91) years. The prevalence of PAD was 42.6% (95% confidence intervals [CI]: 95%: 33.91-52.17%). Among patients with PAD, 95.92% had mild disease and 4.08% moderate to severe disease. The main risk factor for PAD was age (60 years) ( (2) = 3.917, P 0.05). The prevalence was slightly higher in men and hypertensive subjects, but without statistical significance with ORs of 1.5 (95% CI: 0.69-3.21) and 1.42 (95% CI: 0.64-3.17), respectively. Hypertension was also high in the group (66.95%). Conclusion. The prevalence of PAD was 42.6%, higher in those aged 60 years and older. More studies, with representative samples, are necessary to clarify PAD prevalence and associated risk factors.
