PURPOSE
Weight bias internalization (WBI) is associated with disordered eating symptomology and motivation to control weight. The relationship between WBI and specific weight control behaviours and how these behaviours differ between men and women is not well understood. The objectives of this study are to determine (1) the relationship between WBI and weight control behaviours, (2) whether weight perception is independently associated with weight control behaviours, and (3) whether these relationships differ between men and women.
METHODS
Canadian adults (N = 161; 52.8% women; body mass index [BMI] = 26.5 ± 4.99 kg/m) completed questionnaires pertaining to WBI, weight control behaviours (healthy, unhealthy, extreme) and weight perception (accurate, under-, or over-estimation compared with objectively measured BMI). The cross-sectional relationship between (1) WBI or (2) weight perception with the total number of healthy and unhealthy or extreme weight control behaviours, and likelihood of performing specific weight control behaviours were assessed with linear, and logistic regression models, respectively. All analyses were conducted adjusting for age, gender, and race. Subsequent analyses were stratified by sex.
RESULTS
WBI was associated with an increased likelihood of performing exercise for weight loss (OR 2.28, p < 0.05); increased likelihood of skipping meals in women (OR 2.57, p < 0.01), and consuming little amounts of food and food substitutes in men (OR 2.28, p < 0.01 and OR 2.17, p < 0.05, respectively). Weight perception was not associated with weight control behaviours.
CONCLUSIONS
WBI was associated with various weight control behaviours. This study highlights the importance of assessing WBI in clinical practice with patients seeking to manage their weight. Future longitudinal research should be conducted to further understand the behavioural and health effects from WBI.

目的
体重偏见内化（WBI）与饮食失调症状和控制体重的动机有关。WBI 与特定的体重控制行为之间的关系以及这些行为在男性和女性之间的差异尚不清楚。本研究的目的是确定：（1）WBI 与体重控制行为之间的关系；（2）体重感知是否与体重控制行为独立相关；（3）这些关系在男性和女性之间是否存在差异。
方法
加拿大成年人（N=161；52.8%为女性；BMI=26.5±4.99kg/m）完成了与 WBI、体重控制行为（健康、不健康、极端）和体重感知（与客观测量的 BMI 相比，准确、低估或高估）相关的问卷。使用线性和逻辑回归模型分别评估了（1）WBI 或（2）体重感知与健康和不健康或极端体重控制行为总数以及执行特定体重控制行为的可能性之间的横断面关系。所有分析均在调整年龄、性别和种族后进行。随后的分析按性别分层。
结果
WBI 与以下行为的可能性增加有关：（1）为减肥而进行锻炼（OR 2.28，p<0.05）；（2）女性更有可能跳过正餐（OR 2.57，p<0.01），以及男性更有可能少吃食物和食物替代品（OR 2.28，p<0.01 和 OR 2.17，p<0.05）。体重感知与体重控制行为无关。
结论
WBI 与各种体重控制行为有关。本研究强调了在临床实践中对寻求控制体重的患者进行 WBI 评估的重要性。未来应进行纵向研究，以进一步了解 WBI 的行为和健康影响。
