| Outline of Final Research Achievements |
We confirmed the effectiveness of the multi-frequency impedance method in determining body water content as a dehydration index during exercise in young adults under high-temperature environments. However, errors were observed in measurements during daily life, necessitating comprehensive estimation considering pre-measurement behaviour. It was found that homebound elderly with low body water content tended to spend time in high-temperature and high-humidity rooms and tended to wear multiple layers of clothing. Therefore, by focusing on changes in body water content, indoor environmental conditions, and clothing behaviour, it may be possible to assess the risk of dehydration comprehensively. Implementing measures, such as body water content, room temperature and humidity, and observation of the care recipient's drinking and clothing behaviour can improve the awareness of caregivers and elderly care recipients and their families regarding heatstroke prevention.

| Academic Significance and Societal Importance of the Research Achievements |
これまでの熱中症予防に関する指針やガイドラインは健康な自立高齢者を対象に策定されているが、要支援・要介護高齢者に対する脱水の指標は十分検討されていない。また、支援家族や介護員の熱中症防止に関する認識はあるが、サポートを必要とする高齢者への具体的な働きかけは示されていない。要介護在宅高齢者の脱水の危険性を推測するためには、体水分量や室内環境の変化と着衣行動に着目して総合的に判断することが重要である。被介護者の体水分率や居室温湿度の習慣的測定、飲水行動や着衣行動の観察など確認事項を設定して脱水に陥る機序を理解させることが、介護員や被介護高齢者とその家族の熱中症予防への関心や意識を向上させる。
