目的探讨蚌埠市青少年青春发动时相与进食问题的关系,为青少年身心健康成长打好基础。方法按照分层整群抽样的方法,抽取蚌埠市2所九年一贯制学校的五至八年级的学生共831名,采用青春发动问卷(Puberty Development Scale, PDS)和进食障碍问卷(Eating Disorder Inventory-1, EDI-1)进行调查。结果男生青春发动提前组20名,适时组316名,延迟组102名;女生提前组102名,适时组264名,延迟组27名。女生瘦身倾向、不满体型维度得分均高于男生;不同年级学生瘦身倾向、贪食、完美主义、成熟恐惧、无效能感5个维度得分差异均有统计学意义(F值分别为2.68,4.87,6.46,3.07,5.49,P值均<0.05)。男生仅人际不信任维度表现为青春发动延迟组得分高于发动提前组和适时组;而女生瘦身倾向、不满体型和进食障碍总分均为青春发动提前组最高,差异均有统计学意义(P值均<0.05)。结论青春发动时相与青少年进食问题密切相关。青春发动时相的提前和延迟均会影响青少年的进食行为。
