Drinking plain water instead of sugar-sweetened beverages is one approach for reducing energy intake. Only a few studies have examined characteristics associated with plain water intake among US youth. The purpose of our cross-sectional study was to examine associations of demographic characteristics, weight status, dietary habits, and other behavior-related factors with plain water intake among a nationally representative sample of US high school students. The 2010 National Youth Physical Activity and Nutrition Study data for 11,049 students in grades 9 through 12 were used. Multivariable logistic regression analysis was used to calculate adjusted odds ratios (ORs) and 95% CIs for variables associated with low water intake (<3 times/day). Nationwide, 54% of high school students reported drinking water <3 times/day.

Being obese was significantly associated with reduced odds for low water intake (OR 0.7). The findings of these significant associations of low water intake with poor diet quality, frequent fast-food restaurant use, and physical inactivity may be used to tailor intervention efforts to increase plain water intake as a substitute for sugar-sweetened beverages and to promote healthy lifestyles.
KeywordsDrinking water; Dietary intake; Adolescents; Sugar-sweetened beverages; Television Sugar-Sweetened Beverages (Ssbs) are the largest source of added sugar and an important contributor of energy in the diet of US youth. 1 Consumption of SSBs has been associated with obesity, 2-5 dental caries, 6 type 2 diabetes, 7 poor mental health, 8,9 poor academic grades, 10 and displacement of nutrient-rich foods. 11,12 In contrast, drinking plain water instead of SSBs is one approach for individuals trying to reduce dietary energy intake and thereby possibly benefit obesity prevention and control. [13][14][15] Hence, consuming water as part of a healthy diet (eg, one that contains fruits, vegetables, whole grains, low-fat/reduced fat dairy, and lean meats) can aid weight management [13][14][15][16] and, if substituted for SSB consumption, also possibly aver...
