下列哪項行動是針對心血管疾病的初級預防形式？
Which of the following actions is a form of primary prevention for cardiovascular disease?
- AMonitoring blood glucose levels daily每日監測血糖水平
- BGetting an annual stress test接受年度壓力測試
- CStarting a daily low-dose aspirin regimen開始每日低劑量阿斯匹靈療程
- DParticipating in a regular aerobic exercise program✓ 正解參與規律的有氧運動計畫
初級預防（Primary prevention）的核心目標是在疾病發生前，透過健康促進與健康保護手段降低發病機率。有氧運動能改善心肺功能、調節血壓與血脂代謝，從生理層面預防心血管疾病的發生。其餘選項皆涉及針對既有風險因素的藥物干預或疾病篩檢，屬於次級預防（Secondary prevention），即在疾病早期階段進行偵測與阻斷。
The core goal of primary prevention is to reduce the incidence of disease before it develops, through health promotion and health protection. Aerobic exercise improves cardiopulmonary function and modulates blood pressure and lipid metabolism, physiologically preventing the development of cardiovascular disease. The other options involve pharmacologic intervention or disease screening targeting existing risk factors and represent secondary prevention—detection and interruption of disease in its early stages.
