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 provided at least one valid response to questions on participation in leisure time exercise or physical activities. Participants reported the frequency of walking, jogging or running, bicycling or using an exercise bike, swimming, aerobics or aerobic dancing, other dancing, calisthenics or exercises, garden or yard work, and lifting weights in the past month. Four open-ended questions regarding other exercises, sports or physically active hobbies (not mentioned above) were asked. 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. Frequency of activity per week was calculated from frequency of activity reported per month; the frequency reflects the sum of the frequencies calculated for each reported activity.

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