目标:权重偏差内化(WBI)是一个稳健的,负面健康结果的正相关;然而,这个证据基础主要反映了来自西方文化背景的顺性个体。来自非西方文化背景的性别多样化个体(例如,中国)面临WBI的潜在高风险。然而,在这个历史上代表性不足的人群中,没有研究对WBI和相关的负面健康后果进行过调查.
方法:横截面,在线调查对中国不同性别的个体(N=410,Mage=22.33岁)进行了抽样。变量是自我报告的,包括人口统计,WBI,身体羞耻,身体不满,饮食紊乱,身心健康状况,和性别少数群体压力(例如,内化顺势主义)。分析包括相关性和多重分层回归。
结果:Pearson双变量相关性表明,较高的WBI与较多的饮食和身体形象障碍以及不良的身心健康之间存在关联。在调整了年龄之后,BMI,性别认同,和性别少数群体的压力,较高的WBI与较高的身体羞耻具有独特的正相关,更高的身体不满,更多的无序饮食,和不良的身心健康。值得注意的是,WBI在饮食和身体形象障碍方面的差异更大(WBI解释的13%-25%),而不是身体和心理健康(WBI解释的1%-4%)。
结论:虽然需要纵向和实验设计的复制来说明时间动态和因果关系,我们的研究发现WBI是独一无二的,中国不同性别的成年人饮食和身体形象障碍的有意义的关联。
OBJECTIVE: Weight bias internalization (WBI) is a robust, positive correlate of negative health outcomes; however, this evidence base primarily reflects cisgender individuals from Western cultural contexts. Gender-diverse individuals from non-Western cultural contexts (e.g., China) are at potentially high risk for WBI. Yet, no research has examined WBI and associated negative health consequences in this historically underrepresented population.
METHODS: A cross-sectional, online survey sampled Chinese gender-diverse individuals (N = 410, Mage = 22.33 years). Variables were self-reported, including demographics, WBI, body shame, body dissatisfaction, disordered eating, physical and mental health status, and gender minority stress (e.g., internalized cisgenderism). Analyses included correlations and multiple hierarchical regressions.
RESULTS: Pearson bivariate correlations demonstrated associations between higher WBI and more eating and body image disturbances and poor physical and mental health. After adjusting for age, BMI, gender identity, and gender minority stress, higher WBI was uniquely and positively associated with higher body shame, higher body dissatisfaction, higher disordered eating, and poor physical and mental health. Notably, WBI accounted for more unique variance in eating and body image disturbances (13%-25% explained by WBI) than physical and mental health (1%-4% explained by WBI).
CONCLUSIONS: While replication with longitudinal and experimental designs is needed to speak to the temporal dynamics and causality, our findings identify WBI as a unique, meaningful correlate of eating and body image disturbances in Chinese gender-diverse adults.
