What type of prevention is a government health campaign that encourages consumption of low-fat products and low salt intake to decrease risk factors of hypertension and diabetes?

Primordial Prevention

This government health campaign represents primordial prevention (Option A), as it targets the entire population to prevent the development of risk factors (hypertension and diabetes) before they even emerge, rather than treating existing risk factors or disease.

Understanding the Prevention Hierarchy

Primordial Prevention

• Primordial prevention seeks to prevent the development of risk factors themselves in the first place by targeting underlying social, economic, and environmental conditions that lead to disease 1
• This approach focuses on maintaining normal physiological parameters (like blood pressure and glucose levels) and preventing the emergence of risk factors such as hypertension, diabetes, and dyslipidemia 2
• Population-wide campaigns promoting low-fat and low-salt diets exemplify primordial prevention because they aim to prevent risk factors from developing in healthy individuals 1, 2

How This Differs from Primary Prevention

• Primary prevention targets individuals who already have elevated risk factors (like prehypertension or prediabetes) to prevent progression to actual disease 3
• The American Heart Association distinguishes that in primary prevention, dietary changes are used to lower blood pressure in individuals with prehypertension (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) 3
• Primary prevention interventions are directed at specific at-risk individuals, not the general population 4

Why This Campaign is Primordial, Not Primary

• The question describes a population-wide government campaign targeting the general public, not individuals with identified risk factors 3
• The goal is to prevent risk factors (hypertension and diabetes) from developing, not to treat existing elevated blood pressure or glucose levels 1, 2
• Sodium reduction has been identified by the WHO as a "best-buy intervention" for preventing hypertension at the population level through campaigns that include consumer education 3
• This represents primordial prevention because it addresses the entire population before risk factors emerge, maintaining cardiovascular health as the default state 1

Key Distinction in the Evidence

Population-Level vs. Individual-Level Interventions

• The American Heart Association emphasizes that efforts to reduce blood pressure "in both nonhypertensive and hypertensive individuals are warranted," but distinguishes between population strategies (primordial) and individual treatment (primary/secondary) 3
• Government campaigns promoting dietary modifications across entire populations represent structural interventions that "make healthy lifestyles the default option" - the hallmark of primordial prevention 1

The Specific Interventions Mentioned

• Low-salt intake: Reducing sodium consumption prevents the development of hypertension in normotensive individuals 3
• Low-fat products: Preventing dyslipidemia and obesity, which are risk factors for both hypertension and diabetes 3
• These interventions target the general population before risk factors develop, not individuals with established prehypertension or prediabetes 2

Common Pitfall to Avoid

• Do not confuse primordial prevention with primary prevention simply because both involve lifestyle modifications 1, 2
• The critical distinction is the target population: primordial prevention addresses the general population to prevent risk factors, while primary prevention addresses individuals with risk factors to prevent disease 4, 2
