Key result
Among 110 young adults referred to a tertiary hypertension clinic, 78.2% had essential hypertension, 14.5% had secondary causes, and 65.5% exhibited hypertensive organ damage.
Why the study?
To audit young patients referred to the Hypertension Clinic at Groote Schuur Hospital, which predominately serves underprivileged communities of Cape Town.
Observational (n=110)

In young adults referred to a tertiary hypertension clinic in South Africa, the majority had essential hypertension with significant rates of target organ damage and modifiable risk factors.
May inform local hypertension screening in young South Africans; leaves open etiology and organ-damage prevalence.
To audit the young patients referred to the Hypertension Clinic at Groote Schuur Hospital that predominately serves the underprivileged communities of Cape Town.Folders of patients between the ages of 15 and 30 years over a 2 year period were reviewed. The data collected included demographic, clinical and laboratory data, investigations, causes of hypertension, and presence of hypertensive organ damage.Of the 110 patients reviewed, 61 (55.5%) were females, 22 (20%) Black African, and 88 (80%) of Mixed Ancestry. Eight (7.3%) were found to be normotensive, 16 (14.5%) had a secondary cause and 86 (78.2%) had essential hypertension. Thirty five (31.8%) were current or previous smokers, and 11 (10%) admitted to current or prior use of metamphetamines. A family history of hypertension in a first degree relative was present in 80 (72.7%) patients. Comorbidities present were diabetes in 7 (6.4%) patients, metabolic syndrome in 13 (11.8%), and obesity in 26 (23.6%), but 42.6% had a body mass index (BMI) <25 kg/m. Chronic kidney disease (CKD) was present in 29 (26.4%) patients and ECG left ventricular hypertrophy in 56 (50.9%). Overall organ damage was present in 72 (65.5%) patients.In this cohort of young hypertensives most patients had essential hypertension with a strong family history. Significant organ damage was identified. High risk behavior, including smoking and illicit drug use, and obesity were identified as contributing factors. Secondary causes were identified in 14.2%. These results suggest a targeted approach to the investigation of young hypertensives for secondary causes, and significant opportunities for lifestyle intervention.

Jones et al. (2020) conducted an observational in Hypertension (n=110). Young-onset hypertension was evaluated on Causes of hypertension and presence of hypertensive organ damage. Among 110 young adults referred to a tertiary hypertension clinic, 78.2% had essential hypertension, 14.5% had secondary causes, and 65.5% exhibited hypertensive organ damage.
