Introduction
People with
HIV
(
PWH
) are at increased risk for atherosclerotic cardiovascular disease (
CVD
). Screening for
CVD
risk factors is recommended but not routine in South African
HIV
clinics. We sought to describe the prevalence of
CVD
risk factors among antiretroviral treatment (
ART
)‐experienced patients in South Africa.
Methods
We performed a prospective, observational cross‐sectional study of
PWH
(>21 years, excluding pregnant women) on
ART
in South Africa. We interviewed patients regarding
CVD
risk factors, and obtained two blood pressure (
BP
) measurements and random/fasting glucose via a point‐of‐care glucometer. Standardized chart reviews provided individuals'
HIV
‐specific data. We defined hypertension as: self‐reported use of antihypertensives or mean systolic
BP
(
SBP
) ≥140 mmHg or diastolic
BP
(
DBP
) ≥90 mmHg (Stage 1) or
SBP
≥160 mmHg or
DBP
≥100 mmHg (Stage 2). We defined diabetes as self‐reported use of insulin/oral hypoglycaemics or fasting (random) glucose ≥7.0 (≥11.1) mmol. We obtained risk ratios (
RR
) for hypertension from a multivariable log‐binomial regression model, adjusting for age, sex and diabetes.
Results
From March 2015 to February 2016, 458 participants enrolled with median age 38 years (interquartile range (
IQR
) 33 to 44 years) and median
CD
4 466/μL (
IQR
317 to 638/μL); 78% were women. Participants were on
ART
for a median of four years, with 33% on
ART
≥6 years. Almost a quarter (106/458) met the study definition for hypertension, of whom 45/106 (42%) were previously diagnosed, 23/45 (51%) were on medication and 4/23 (17%) were controlled. Eight participants had asymptomatic hypertensive urgency (
BP
≥180/110 mmHg). Of the 458 participants, 26 (6%) met the study definition for diabetes, half of whom (13/26) were already diagnosed; 11/13 (85%) were on treatment, of whom 4/11 (36%) had normal glucose. Age was the only significant predictor of hypertension (
RR
, 1.04; 95%
CI
, 1.03 to 1.06,
p
< 0.0001) in the multivariable model.
Conclusions
Hypertension and diabetes were prevalent among
PWH

ART
in South Africa with less than half diagn...
