一級預防（Primary Prevention）致力於「健康促進」與「疾病預防」，目標是讓健康的人群不罹患疾病。提供學校健康午餐能從根本改善兒童營養攝取，預防肥胖與營養不良，屬於此範疇。皮膚癌篩檢屬於二級預防（早期偵測），胰島素治療與物理治療則屬於三級預防（疾病治療與復健），旨在減少已發生疾病的影響並防止失能。
Primary prevention focuses on health promotion and disease prevention, with the goal of keeping healthy populations free of disease. Providing healthy school lunches fundamentally improves children's nutritional intake and helps prevent obesity and malnutrition, placing it in this category. Skin cancer screening is secondary prevention (early detection), while insulin therapy and physical therapy are tertiary prevention (treatment and rehabilitation of existing disease) aimed at reducing the impact of disease and preventing disability.
