a M = male, F = female.

b Total water intake reflects the sum of drinking water and the water content of foods and beverages.

NOTE: Data are limited to individuals who provided a valid response to a question on usual plain drinking water intake, provided a complete and reliable 24-hour dietary recall, and had a serum osmolality measurement. Females who were pregnant, lactating, or had “blank but applicable” pregnancy or lactating status data or who responded “I don’t know” to questions on pregnancy or lactating status were excluded from the analysis.
