Summary

The study investigates self-reported hypertension prevalence, risk factors, and knowledge among South Africans aged 24 to 40 years. It highlights the alarming issue of hypertension in young adults. The study reveals a high prevalence of hypertension, with significant differences between women and men. It also emphasises a lack of awareness about hypertension among the youth. The study stresses the importance of early preventative strategies and the role of community health workers in managing hypertension effectively.

Key Insights

• High Prevalence of Hypertension: The study found a high self-reported prevalence of hypertension among young adults. It was 27.5% among women and 20.4% among men.
• Lack of Knowledge: Despite the high prevalence, there is a lack of knowledge about hypertension among this age group. Most individuals reported only intermediate knowledge.
• Protective Factors: Factors such as full-time employment, higher socioeconomic status, regular physical activity, and avoiding alcohol consumption were identified as protective against hypertension.
• Preferred Interventions: Young adults expressed a preference for interventions involving community health workers for education and regular blood pressure checks.

Background Context

Hypertension is a significant health issue in South Africa, with a high prevalence among adults. The age-standardised prevalence of hypertension in the country is approximately 35.1%. Sub-Saharan Africa, including South Africa, faces challenges such as low awareness, treatment, and control of hypertension. The World Health Organization identifies modifiable risk factors like physical inactivity and excessive alcohol consumption as key contributors to hypertension.

Implications

The study’s findings have significant implications for health economics and outcomes research:

• Early Intervention: Implementing early preventative strategies during young adulthood could help reduce the burden of hypertension and related cardiovascular diseases in later life.
• Community-Based Interventions: Utilizing community health workers for education and regular blood pressure checks could enhance awareness and management of hypertension among young adults.
• Healthcare Access: The study highlights the importance of access to healthcare services, particularly for individuals with higher socioeconomic status, in effectively managing hypertension.
• Economic Impact: Reducing the prevalence of hypertension through effective management could lead to substantial economic benefits by lowering healthcare costs associated with cardiovascular diseases.
