Which of the following public health actions is an example of primordial prevention?

• A Cardiac rehabilitation and graded exercise programme after acute myocardial infarction
• B Immunising infants with hepatitis B vaccine to prevent chronic liver disease
• C Annual blood pressure measurement of all adults above 30 years in a village
• D National school policy promoting daily physical activity and healthy diets in children to prevent the future emergence of obesity and insulin resistance ✓

Explanation

Primordial prevention prevents the emergence and establishment of risk factors in a population, acting on social and environmental conditions before risk factors even appear. Building physical activity and healthy eating into childhood lifestyles stops obesity and insulin resistance from ever developing. Immunisation removes a causative agent and is primary prevention. Blood pressure screening is secondary prevention, and post-infarction rehabilitation is tertiary prevention aimed at limiting disability.
