目的了解深圳市罗湖区中学生饮食相关行为对超重肥胖的影响,为制定干预措施提供科学依据。方法使用《中国青少年健康相关行为调查问卷》,采用分层整群抽样方法,对罗湖区2 639名中学生进行饮食相关行为问卷调查。结果学生超重肥胖的总检出率为12.1%,男生(14.5%)高于女生(10.2%)差异有统计学意义(χ2=11.11,P<0.05)。校正年龄和性别之后,随着早餐摄入次数减少(OR=1.63,95%CI=1.21~2.19)和西式快餐摄入次数增加(OR=1.41,95%CI=1.07~1.85),与超重肥胖的发生风险增加存在统计学意义的关联。结论深圳市罗湖区中学生不良饮食行为增加超重肥胖的患病风险,应该根据年龄特点实时开展合理膳食教育,从而预防超重肥胖的发生。
