在校大学生对超重肥胖的认知情况及减肥行为调查

目的了解在校大学生对超重肥胖的认知情况及减肥行为现状,为今后健康教育提供科学依据。方法采用随机整群抽样的方法,在全国10个省市15所大学中随机选取2599名在校大学生作为调查对象,采用问卷调查的方法收集大学生对超重肥胖的认知及减肥行为等信息。结果男生的超重肥胖率（12.8%）明显高于女生（2.9%）;女生中体重过低的占34.6%,明显高于男生（12.1%）。33.2%的大学生采取过减肥措施,女生（43.5%）明显高于男生（23.6%）。51.5%减过肥的大学生采取的是＂适量运动＋控制饮食＂的减肥方式,但仍有29.1%主要靠＂节食＂来减肥,尤其是女生（33.0%）。有54.1%＂超重肥胖＂的大学生未采取过任何减肥措施,男生比例（57.5%）明显高于女生（37.1%）。有27.1%＂体重过低＂的大学生曾经减过肥,女生（31.4%）高于男生（15.9%）。在曾经减过肥的大学生中,只有11.2%的大学生处于超重肥胖,18.6%的大学生处于体重过低的情况,女生中这种情况更加严重。结论在校大学生对自身的超重肥胖有不正确认识,因关注程度不足而未采取任何减肥措施的现象在＂超重肥胖＂男生中非常突出;因过分追求体型消瘦而盲目减肥的现象在＂体重过轻＂女生中尤为突出。建议引导在校大学生进行科学健康的减肥,养成健康的生活方式。
