目的探讨广东省正常体重中学生体重认知偏移对自杀意念的影响。方法利用广东省2004年与2007年青少年健康危险行为监测资料，从中选择12～18岁体重正常的12729名中学生为研究对象。在调整了年龄、经济状况、母亲文化程度、精神状态、抑郁症状等的影响后，采用非条件logistic回归分析体重正常中学生体重认知偏移与自杀意念的关系。结果在调查的12729名中学生中，男性6096名，女性6633名。过去12个月内，广东省正常体重中学生自杀意念的发生率为13.58％(1729/12729)，女性(16.15％，1071/6633)高于男性(10.79％,658/6096)(x2=77.71，P=0.00)。调查对象中只有44.93％(5719/12729)能正确认知自己的体重，体重认知偏移在中学生中普遍存在，其中43.52％ (5540/12729)高估了自己的体重，11.43％( 1455/12729)低估了自己的体重。女生体重认知偏移率(65.58％,4350/6633)明显高于男生(43.39％,2645/6096)( x2= 993.91，P=0.00)。在调整了年龄、城乡分布、母亲文化程度、精神状况、抑郁症状等的影响后，高估自己体重者发生自杀意念的危险性是体重正确认知者的1.43倍（OR=1.43,95％CI：1.27～1.61）。结论广东省中学生体重认知偏移发生率高，体重认知偏移与自杀意念有关，高估体重者更容易发生自杀意念。

Objective To explore the relationship between distorted weight perception and suicide ideation among normal weight adolescents in Guangdong province. Methods This study used the data of Guangdong Provincial Youth Health Risk Behavior Survey in 2004 and 2007. To identify the association between distorted weight perception and suicide ideation, a logistic regression analysis was performed. The effects of age, economic status, mother's education, mental health, and depression were also adjusted.Results A total of 12729 people participated in this study,6096 males and 6633 females. The prevalence of suicide ideation among normal weight adolescents was 13.58％ ( 1729/12729) in the past 12 months,with higher prevalence in girls ( 16.15％ ,1071/6633) than that in boys ( 10.79％ ,658/6096) ( x2 =77.71 ,P =0.00). It was common that the adolescents misperceived their weight. Only 44.93％ (5719/12729) of normal weight students correctly perceived their body weight while 43.52％ (5540/12729 ) of them overestimated their weight and 11.43％ (1455/12729 )underestimated their weight. The distorted weight perception in girls ( 65.58％, 4350/6633 ) was higher than that in boys ( 43.39％, 2645/6096 ) ( x2 =993.91 ,P= 0.00 ). Distorted weight perception was significantly associated with suicide ideation after controlling for factors age,economic status, mother's education, mental health, and depression. The students who overestimte their body weight were more likely to have suicide ideation than that who correctly perceived their weight ( OR = 1.43,95％ CI: 1.27 - 1.61 ) . ConclusionThe prevalence of distorted weight perception was high and it significantly associated with suicide ideation.
