一位 20 歲大學生進行常規健檢。下列哪項健康促進主題最適合此年齡層？
A 20-year-old college student presents for a routine check-up. Which health promotion topic is most age-appropriate?
- APreparation for retirement planning退休規劃準備
- BScreening for prostate cancer攝護腺癌篩檢
- CManagement of menopausal symptoms更年期症狀管理
- DSexual health and safe sex practices✓ 正解性健康與安全性行為實踐
健康促進應根據個案的發展階段（Developmental Stage）進行。20 歲屬於成年早期（Young Adulthood），此階段的主要發展任務包括建立親密關係與性健康維護。安全性行為、性傳染病（STI）預防及避孕諮詢是此年齡層最切身且必要的健康促進議題。其他選項均屬於中老年後的篩檢或規劃議題，不符合此年齡層的生理與心理需求。
Health promotion should be tailored to the client's developmental stage. A 20-year-old is in young adulthood, during which the primary developmental tasks include establishing intimate relationships and maintaining sexual health. Safe sexual practices, prevention of sexually transmitted infections (STIs), and contraceptive counseling are the most immediate and essential health-promotion topics for this age group. The other options pertain to screening or planning issues relevant only to middle or older adulthood and do not match the physiological and psychological needs of this population.
