護理師在社區進行衛教，下列哪項是心血管疾病的「可修正」危險因子？

「可修正」危險因子是指那些可以透過行為改變、生活習慣或藥物治療來進行調整的因素。久坐不動（Sedentary lifestyle）是心血管疾病的重要危險因子，個案完全可以透過增加規律的身體活動來修正此狀況。其他選項（年齡、性別、遺傳/基因）皆屬於個體生物學特徵，是無法透過後天行為更改的「不可變更」因素。

A 'modifiable' risk factor is one that can be adjusted through behavior change, lifestyle modification, or pharmacologic treatment. A sedentary lifestyle is a significant risk factor for cardiovascular disease that the client can fully modify by increasing regular physical activity. The other options (age, gender, genetics) are intrinsic biological characteristics and are classified as non-modifiable factors that cannot be changed through acquired behavior.
