Preliminary data suggest that low water intake is associated with the risk of developing diabetes, while most of U.S. adults do not meet the requirements for daily water intake. PURPOSE: To study the effect of high water intake on glucose regulation in healthy adults. METHODS: 2,233 participants from 2009-10 & 2011-12 National Health and Nutrition Examination Survey were selected to examine the association between water intake and hydration state with insulin resistance in healthy individuals (females: 48.3%, age: 44±1 y, BMI: 27.5±0.2 kg∙m-2) in the US. RESULTS: Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR) and data were divided into tertiles (≤1.77, 1.78-3.45, and >3.45). Hydration status was assessed by urine osmolality (621±7 mmol∙kg-1) and urine flow rate (0.96±0.03 ml∙min-1). Plain water (1,203±35 mL) and total water intake (TWI; 3,190±43 mL) was assessed from a 24 h dietary recall. Urine osmolality was highest in the upper HOMA tertile (679±9 mmol∙kg-1) compared to lowest tertile (583±1 mmol∙kg-1, P<0.001), while urine flow rate was highest in the lowest HOMA-IR tertile (1.03±0.04 ml∙min-1) compared to upper tertile (0.92±0.03 ml∙min-1, P=0.001). Multinomial logistic regression showed healthy adults who consumed more plain water (≥859 mL) were half as likely to be in the upper HOMA-IR tertile, compared with their peers who consumed less (≤207 mL, OR=0.50; 0.34-0.73), after adjusting for age, gender, BMI, waist circumference, race/ethnicity, education, and physical activity. Similarly, adults with higher levels of daily TWI (≥2,657 mL) had significantly lesser odds (42%) of being in the upper HOMA tertile, compared to adults with a lower level of TFI (1,598 mL, OR=0.58; 0.38-0.90). CONCLUSION: Higher plain water (≥859 mL) and total water intake (≥2,657 mL), as well as better hydration state were associated with lower insulin resistance.
