了解上海市护理专业女大学生对自身体重感知的准确程度,探讨产生体重感知偏差的影响因素,以期为纠正女大学生体重感知偏差、开展学校健康教育提供实证依据.方法 采用方便抽样方法,选取上海市4所医学院校的600名护理专业女大学生,进行体重感知及其影响因素的线上问卷调查.结果 护理专业女大学生能准确感知自身体重水平的仅占44.50%(267名),对自身体重高估的比例高达53.83%(323名),感知体重水平与实际体重水平的一致性较差(Kappa=0.20).护理专业女大学生对自身体重高估的影响因素有自身实际体重水平(OR=0.09~15.02)、自认在同伴中的体重水平(OR=17.85 ~ 202.67)、媒体所展示的女性形象对减肥想法的影响(OR=3.21~6.14)、生活地区(OR=1.12~2.55)和肥胖刻板印象(OR=0.98)(P值均<0.05).结论 护理专业女大学生对自身体重感知的准确率不高,有高估体重的倾向.

Body weight misperception and associated factors among female nursing students in Shanghai

Objective To explore the prevalence of body weight misperception and its influencing factors among female nursing students in Shanghai. Methods A total of 600 female nursing students from 4 medical colleges in Shanghai were recruited by a convenient sampling method and investigated weight perception and associated factors through online questionnaires. Results Only 44. 50%( 267) participants accurately described their body weight,and the proportion of body weight overestimation was53.83%( 323). The consistency between perceived weight status and actual weight status was poor( Kappa = 0.20). Factors affecting weight overestimation among female nursing students were personal actual weight levels( OR = 0.09-15.02),self-recognized weight level among peers( OR = 17.85-202.67),the influence of female image in the media on weight loss ideas( OR = 3.21-6.14),living area( OR = 1.12-2.55) and stereotypes of obesity( OR = 0.98)( P<0.05). Conclusion Female nursing students have low rate of accurate estimation of body weight and tend to overestimate.
