Abstract:
Objective:To investigate the food source of water of college students from Hebei Province in spring.
Methods:In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. All foods were collected for 3 consecutive days using duplicate portion study combined with weighing method to test the water content of various foods. To analyze the water content of the food and calculate the proportion to the total amount of food water intake, the edible parts of each meal were divided into staple food, dishes, porridge, soup and snacks. Body mass index (BMI) was grouped according to quartiles, and the differences in food intake and food water sources among subjects of different genders and BMI were compared.
Results:The age of subjects was (19.8±1.1) years old, including 80 male students. The median intake of staple food, dishes, porridge, soup and snacks per day was 562 g, 743 g, 111 g, 102 g and 0 g, respectively. The median intake of water from staple food, dishes, porridge, soup and snacks per day was 301 ml/d, 620 ml/d, 97 ml/d, 93 ml/d and 0 ml/d, respectively. The median ratio of water intake to total food water intake of staple food, dishes, porridge, soup and snacks was 27%, 53%, 8%, 8% and 0%, respectively. The median intake of water from staple food and dishes in male students was significantly higher than that of female students (P<0.05). The amount of water intake from porridge of female students was significantly higher than that of male students (P<0.05). There was no significant difference in the water intake from soup and snacks between different genders. There was no significant difference in food intake and food water sources among college students with different BMI (P>0.05).
Conclusion:The food source of water of college students from Hebei Province in spring is mainly based on dishes and staple foods. The food source of water for boys and girls is different.
