目的：探讨对外表的社会文化态度、身体欣赏、直觉进食和不健康体重控制行为之间的关系及这种关系是否存在性别差异。方法：采用对外表的社会文化态度量表、身体欣赏量表、直觉进食量表和不健康体重控制行为量表分别对662名女中学生和482名男中学生进行调查。结果：(1)在中学生中社会文化态度、身体欣赏、直觉进食和不健康体重控制行为两两之间均显著相关；(2)在女中学生中，身体欣赏、直觉进食在社会文化态度和不健康体重控制行为之间起链式中介作用；而在男中学生中，身体欣赏、直觉进食在社会文化态度和不健康体重控制行为之间起平行中介作用。结论：青少年对外表的社会文化态度与不健康体重控制行为的关系受身体欣赏、直觉进食单独中介作用影响；在女生中，该关系也受到身体欣赏和直觉进食的链式中介作用影响。
