提高儿童青少年饮水素养 加强水合状态与健康研究

Improve the drinking water literacy of children and adolescents and to strengthen the study of hydration state and health

摄入充足水分、维持身体适宜水合状态,对于促进身体健康至关重要。儿童青少年进行身体活动时,由于运动强度、能量消耗和环境温湿度的不同,对水的需要量也不同,出现饮水不足和脱水状态的风险更高。但水的重要性未得到足够重视,儿童青少年饮水健康素养有待提高。儿童青少年普遍存在饮水不足和处于脱水状态的现象,一定程度的脱水会降低其认知能力和身体活动能力,给予饮水健康宣教或饮水干预后有所改善。有必要开展更多儿童青少年饮水行为调查、水合状态与健康影响的研究和饮水健康宣教,提高儿童青少年饮水健康素养,以促进足量饮水、合理选择饮水类型和维持适宜水合状态,进而促进身体健康。

Water has many physiological functions and is one of the essential substances for human survival and development.It is very important to take enough water and keep adequate hydration state.When children and adolescent are in physical activity,due to the different intensity of physical activity,energy consumption and environmental temperature and humidity,the water demand is also different.The risk of insufficient water intake and dehydration is higher among people in physical activity.However,the importance of water has not been paid enough attention,and the literacy on hydration state and health among children and adolescent needs to be improved.Children and adolescents generally had insufficient water intake and were dehydrated.Existing research showed that dehydration could reduce the cognitive ability of children and adolescents,and the cognitive ability could be improved after health education or water intake intervention.Scientific water supplement or electrolyte supplement and energy drink could help to improve the ability of physical activity.It is necessary to carry out more investigation on behavior of water intake and more researches on hydration state and health impacts among children and adolescent.It is also necessary to carry out water intake related health education children’s and adolescents’,so as to improve their the literacy on hydration state and health,and to promote sufficient water intake and reasonably choose on water type,to maintain appropriate hydration state,and then to promote their health.
