下列何者描述了健康博覽會中膽固醇篩檢的目的？

健康博覽會（Health fair）提供的膽固醇篩檢，其目的在於「早期偵測」。因為高膽固醇血症在初期通常無症狀，透過篩檢找出高危險群，進而給予衛教或轉介治療，這屬於二級預防（Secondary prevention）。一級預防則是針對尚無風險的健康族群進行健康促進，三級則是針對已患病者進行復健與防止惡化。

Cholesterol screening offered at a health fair is aimed at early detection. Because hypercholesterolemia is typically asymptomatic in its early stages, screening identifies high-risk individuals so that health education or referral for treatment can be provided; this constitutes secondary prevention. Primary prevention targets healthy populations who are not yet at risk through health promotion, whereas tertiary prevention focuses on rehabilitation and prevention of further deterioration in individuals who already have the disease.
