大学生饮食行为与尿无机盐排出量关系研究

目的探讨大学生的饮食行为与尿无机盐排出量的关系,为开展营养健康教育提供依据。方法采用自编调查问卷,对某医学院802名大学生的每月生活费、每天喝奶情况、饮食种类等进行调查,同时检测尿钙及尿磷排出量,并计算与尿肌酐的比值。结果不同性别大学生尿钙磷水平差异无统计学意义(P>0.05),不同饮用牛奶频次、不同饮食种类及不同生活费用组其差别均有统计学意义(P值均<0.01)。结论不合理的膳食结构是影响尿钙、磷的重要因素之一。必须提高和加强学生的营养意识,纠正不良的饮食行为。

Objective To explore the relationships between dietary behaviors and urinary inorganic salts of college students, and to provide bases for nutritional health education. Methods By using a self-designed questionnaire, 802 medicos were investigated on living expense, milk intakes and dietary categories. The urinary calcium, phosphorous and creatinine contents were detected and the ratios were calculated. Results No statistical significance of urinary calcium and phosphorous were found between students of different genders (P>0.05). There were statistical significance between the students in the groups of milk frequency, dietary categories and living expenses (P<0.01). Conclusion Urinary calcium and phosphorous is influenced by the constitution of diets. The awareness of college students of nutrition should be enhanced and their unhealthy habits of dietary should be correct.
