摘要:
了解哈尔滨城乡地区中小学生生活习惯对其营养状况的影响,为指导中小学生养成健康的生活方式提供基础数据.方法 于2014年9月随机抽取哈尔滨市城乡的小学(四、五年级)、初中、高中各1所学校,采用2014年全国学生体质与健康调研学生问卷对5 016名学生进行问卷调查以及身高、体重现场测量.结果 城市学生中睡眠时间<8h/d的占62.0%,乡村地区睡眠<8 h/d的占55.1%;城、乡地区不吃早餐的学生占1.2%和3.1%;城乡地区分别有27.5%和28.4%的学生认为课业负担过重应付不来;城乡地区学生每天体育锻炼时间不足30 min的比例分别为27.7%,24.9%.城乡学生的睡眠时间、吃早餐情况、喝牛奶、吃鸡蛋、课业负担感受、每天做作业时间、看电视玩游戏时间、每天体育锻炼时间、上体育课的感受差异均有统计学意义(x2值分别为30.80,46.50,110.86,18.41,56.48,186.83,117.40,147.87,119.58,P值均<0.01).学生的体质量指数(body mass index,BMI)整体上随着年龄的增长而增大,9,13,14,17岁城乡男女生之间BMI差异均有统计学意义(P值均<0.05).哈尔滨地区学生仍存在营养不良和超重肥胖的现象,尤以超重、肥胖情况严重,并且男生检出率高于女生,但营养不良状况男女生之间的比较与之相反.多元线性回归分析结果显示,愿意参加长跑锻炼、每天平均睡眠时间、上体育课时的感觉、平均每天作家庭作业的时间、每周吃鸡蛋情况、平均每天看电视、玩游戏的时间、父母在业余时间里是否喜欢参加体育活动、每周吃早餐情况是中小学生营养状况的重要影响因素.结论 哈尔滨城、乡中小学生中依然存在着不良生活习惯现象,对学生的生长发育会产生不良的影响.
