Determinant of factors associated with water requirement measured using the doubly labelled water method among older Japanese adults.

ABSTRACT:

Objective

Water is an essential nutrient for all organisms and is important for maintaining life and health. We aimed to develop a biomarker-calibrated equation for predicting water turnover (WT) and pre-formed water (PW) using the doubly labelled water (DLW) method.

Design

Cross-sectional study.

Setting

General older population from the Kyoto-Kameoka Study, Japan.

Participants

The 141 participants aged ≥ 65 years were divided into a model developing (n 71) and a validation cohort group (n 70) using a random number generation. WT and PW was measured using the DLW method in May-June of 2012. In developing the cohort, equations for predicting WT and PW were developed by multivariate stepwise regression using all data from the questionnaires in the K
