摘要
目的了解深圳市宝安区二年级小学生的饮食行为现状及其影响因素,为有针对性地开展学生饮食行为干预提供依据。方法采用随机整群抽样方法,抽取宝安区10所学校二年级共918名学生及家长进行饮食相关行为调查,用多元线性回归方法分析小学生饮食行为的影响因素。结果二年级小学生每周食用6 d及以上牛奶、蔬菜、水果的报告率分别为60.24%、69.28%、60.02%;经常看生产日期、阅读营养标签、参与买菜和做饭的报告率分别为66.45%、59.04%、25.05%,仅有11.22%的学生从不偏食、挑食。多因素分析显示,女生的饮食行为好于男生(β的95%CI=0~0.67,P=0.048),学生营养知识(β的95%CI=0.17~0.33,P<0.001)、家长饮食行为(β的95%CI=0.16~0.34,P<0.001)、学生运动时间(β的95%CI=0.29~0.63,P<0.001)和学生认为营养知识的重要性(β的95%CI=1.14~2.23,P<0.001)等可促进学生养成良好饮食行为习惯。结论本区二年级小学生不良饮食行为普遍存在,其饮食行为主要受性别、学生营养知识态度和家长行为的影响。
