[ABSTRAKStatus hidrasi dipengaruhi oleh banyak faktor termasuk usia. Perubahan fisiologisyang terjadi pada lansia yaitu penurunan sensasi rasa haus, penurunan sekresialdosteron, dan penurunan fungsi luhur dapat menyebabkan peningkatan risikodehidrasi pada lansia. Penelitian analitik observasional dengan metode potonglintang telah dilakukan di rumah binaan lansia Atmabrata, Cilincing Jakarta Utara,dengan tujuan untuk menilai status hidrasi pada lansia dan faktor-faktor yangberhubungan yaitu asupan cairan dan aktivitas fisik. Lima puluh sembilan subjekberhasil menyelesaikan protokol penelitian. Hasil penelitian menunjukkan bahwa27,1% lansia mengalami dehidrasi dengan menggunakan indikator berat jenis urindan 49,2% lansia tidak terhidrasi dengan baik dengan menggunakan indikatorwarna urin. Rerata asupan cairan subjek adalah 1327,97 ± 407,75 mL, danterdapat 72,9% subjek dengan aktivitas fisik rendah. Tidak terdapat hubunganantara status hidrasi dengan asupan cairan (p>0,05), dan sebaliknya terdapathubungan yang bermakna antara berat jenis urin dengan tingkat aktivitas fisik (p<0,001).

ABSTRACTHydration status can be affected among others by age. Dehydration risk is higherin the elderly. Physiological changes such as decreasing sensation of thirst,decreasing secretion of aldosterone and impaired cognitive fuction could be thecauses of dehydration among elderly. Analytic observational by using crosssectional study design conducted in Atmabrata nursing home, Cilincing NorthJakarta has been done to asses hydration status in the elderly and its relatedfactors, i.e fluid intake and physical activity. Fifty nine subjects accomplished thestudy protocol. Based on the urine specific gravity measure, it shows that 27.1%elderly was dehydrated and by using urine color chart, it shows that 49.2% elderlywas not hydrated properly. The fluid intake average of the subject was 1327.97 ±407.75 mL, and there was 72.9% subject with low physical activity. There was nosignificant association between hydration status and fluid intake (p>0.05). Therewas significant association between urine specific gravity status and level physicalactivity (p<0.001)., Hydration status can be affected among others by age.
