The role of obesity in the relation between total water intake and urine osmolality in US adults, 2009-2012.

ABSTRACT:

Background

Adequate water intake is critical to physiologic and cognitive functioning. Although water requirements increase with body size, it remains unclear whether weight status modifies the relation between water intake and hydration status.

Objective

We examined how the association between water intake and urine osmolality, which is a hydration biomarker, varied by weight status.

Design

NHANES cross-sectional data (2009-2012) were analyzed in 9601 nonpregnant adults aged ≥20 y who did not have kidney failure. Weight status was categorized with the use of body mass index on the basis of measured height and weight (underweight or normal weight, overweight, and obesity). Urine osmolality was determined with the use of freezing-point depression osmometry. Hypohydrati
