南宁市大中学生减肥行为现状

Weight loss behaviors among college and high school students in Nanning

目的了解在校大中学生对肥胖的认知情况及减肥行为现状,为采用相应健康教育措施提供参考依据。方法采用分层随机整群抽样的方法,对南宁市8所大中学校共3 571名学生,使用中国城市青少年健康危险行为调查问卷进行调查。结果 35.20%的大中学生认为自己体重超重,且中学生的报告率明显高于大学生。锻炼减肥为大中学生的首选方法(55.08%),其余依次为限食(26.6%)、不吃肉(8.26%)、长时间禁食(3.08%)、私自服用减肥药(1.62%)。结论大中学生对自身体型满意度偏低,大多数会选择以锻炼为主的减肥方式,但也存在盲目减肥和减肥方法不合理现象。应对大中学生开展肥胖与科学减肥相关知识的健康教育。
