'age-management' originates from Modern English as a compound of 'age' and 'management', where 'age' referred to a period of life and 'management' referred to the act of handling or controlling. 「age-management」は現代英語の合成語で、『age』は『人生の期間』を、『management』は『扱うこと・管理すること』を意味する語から成る。

'age' comes from Old French 'aage' (also spelled 'aage' or 'age') ultimately from Latin 'aetatem' (nominative 'aetas'), meaning 'age' or 'period of life'; it entered Middle English as 'age'. 'Management' derives from Old French and Italian roots such as Italian 'maneggiare' (to handle, from Latin 'manus' meaning 'hand') with the noun-forming suffix '-ment', passing into Middle French and then into English as 'management'. 「age」は古フランス語の'aage'（ラテン語の'aetatem'に由来し『年齢・人生の期間』を意味）から中英語に入った語である。『management』はイタリア語の'maneggiare'（ラテン語'manus'（手）に由来）や古フランス語形を経て英語に入った名詞形である。

As a compound, 'age-management' initially simply denoted the handling or management of matters related to age; over time it has developed specialized senses in medicine and organizational policy — referring both to anti-aging interventions and to workplace/organizational age policies. 当初は『年齢に関する事柄の扱い』という一般的な意味だったが、時間とともに医療的なアンチエイジング対策や職場の年齢政策など専門的な意味合いを帯びるようになった。
