Objective The objective of this study was to examine plain water intake of Korean adults according to anthropometric, dietary, and food consumption characteristics. Methods This study was conducted using data from the 2008– 2010 Korean National Health and Nutrition Examination Survey. The subjects were 5,917 men and 8,511 women aged 20–64 years. Water intake was estimated by asking the question “How much water do you usually consume per day?” in the questionnaire. Dietary intake was estimated by 24‐hour dietary recall. A food frequency questionnaire including 63 food items was also administered. Lean body mass and percentage of body fat were measured by dual‐energy X‐ray absorptiometry. Results The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively (1 cup = 200ml). Water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, water intake increased. However, as energy‐adjusted fat and carbohydrate consumption increased, water intake decreased in men. Water intake increased as energy‐adjusted protein and energy‐adjusted fiber consumption increased in women. As total weight of food intake and total volume of food intake increased, water intake increased. Water intake according to consumption of vegetables was increased in men and women. In the male subjects, water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased. In the female subject, water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda. Conclusions Our results suggest that people who had a higher BMI and ingested more food consumed more water. Plain water intake was influenced by the particular types of food ingested such as grains, meat, vegetables, fruits, and beverages.
