The majority of Canadian adults are not meeting the recommended physical activity and sedentary behaviour guidelines. Previous studies have highlighted experiences of weight bias as a potential barrier to physical activity and an enabler of sedentary behaviours. Few studies have examined whether endorsing or internalizing weight bias is associated with these health behaviours. A secondary analysis was conducted on a sample of Canadian adults (N = 891, 52% female, mean age group = 45-54 years; mean body mass index [BMI] = 27.04 ± 6 kg/m). Participants completed the International Physical Activity Questionnaire, the Sedentary Behaviour Questionnaire, the Modified Weight Bias Internalization Scale, and the Anti-Fat Attitudes Questionnaire (explicit weight bias). Linear regressions were conducted to determine the relationships between weight bias internalization (WBI), explicit weight bias, physical activity and sedentary behaviours. WBI predicted more weekly hours spent engaging in sedentary behaviours (F(6,897) = 14.73, p <.001, R = 0.09) and anti-fat attitudes (AFA) predicted more weekly minutes of vigorous physical activity (F(6,891) = 5.42, p <.001, adj. R = 0.03). WBI was not significantly associated with physical activity at any intensity. AFA was not significantly associated with sedentary behaviour, or moderate and mild physical activity. Findings suggest that some elements of weight bias may be related to certain health behaviours like sedentary behaviours and physical activity. Our results warrant further study on other factors that may play a role in the relationships between weight bias and health behaviours. Future research should include longitudinal studies and interventions that investigate the impact of weight bias on health behaviours.
大多数加拿大成年人未达到建议的身体活动和久坐行为指南要求。以往研究强调体重偏见经历是身体活动的潜在障碍和久坐行为的促成因素。很少有研究考察认同或内化体重偏见是否与这些健康行为相关。对一组加拿大成年人样本（N = 891，52%为女性，平均年龄组为45 - 54岁；平均体重指数[BMI]=27.04±6 kg/m²）进行了二次分析。参与者完成了国际身体活动问卷、久坐行为问卷、改良的体重偏见内化量表和反胖态度问卷（明确的体重偏见）。进行线性回归以确定体重偏见内化（WBI）、明确的体重偏见、身体活动和久坐行为之间的关系。WBI预测每周花在久坐行为上的时间更多（F(6,897)=14.73，p <.001，R = 0.09），反胖态度（AFA）预测每周剧烈身体活动的分钟数更多（F(6,891)=5.42，p <.001，调整后R = 0.03）。WBI与任何强度的身体活动均无显著关联。AFA与久坐行为、中度和轻度身体活动均无显著关联。研究结果表明，体重偏见的某些因素可能与久坐行为和身体活动等特定健康行为有关。我们的结果值得进一步研究可能在体重偏见与健康行为之间的关系中起作用的其他因素。未来的研究应包括纵向研究和干预措施，以调查体重偏见对健康行为的影响。
