Summary

Stroke risk factors are common in South Africa, with hypertension being the most prevalent. Early screening and treatment by general practitioners (GPs) can help reduce the stroke burden.

Area of Science:

  • Public Health
  • Epidemiology
  • Cardiovascular Medicine

Background:

  • Stroke incidence is rising in sub-Saharan Africa, necessitating effective prevention strategies.
  • General practitioners (GPs) play a crucial role in managing stroke risk factors.
  • Understanding risk factor prevalence in diverse populations is key to targeted interventions.

Purpose of the Study:

  • To determine the prevalence of stroke risk factors within the South African general practice population.
  • To identify variations in risk factor distribution across different demographic groups.

Main Methods:

  • A multicentre, observational study involving 200 general practices across South Africa.
  • Data collected from 9,731 patients aged 30 years and older attending general practice.

Related Experiment Videos

  • Risk factors documented by GPs based on patient information sheets.

    • Main Results:

    • 76% of participants had at least one stroke risk factor; 40% had two or more.
    • Hypertension was the most common risk factor (55%), highest in black patients (59%).
    • Dyslipidaemia prevalence varied by ethnicity (highest in whites, 37%), as did diabetes (highest in Asians, 24%).

    Conclusions:

    • Stroke risk factors are highly prevalent across all South African population groups, with distinct distributions.
    • Significant opportunities exist for stroke burden reduction through GP-led screening and management.
    • Targeted interventions based on demographic-specific risk factor prevalence are recommended.
