Area of Science:

• Public Health
• Epidemiology
• Sociomedical Sciences

Background:

• Chronic illnesses represent a significant public health concern globally.
• Understanding the prevalence and epidemiology of chronic diseases is crucial for effective health planning.
• Previous data on chronic illness distribution across different communities in Cape Town was limited.
