This study aimed to examine the onset of workplace bullying as a risk factor for BMI increase.
Repeated biennial survey data from three Nordic cohort studies were used, totaling 46,148 participants (67,337 participant observations) aged between 18 and 65 who did not have obesity and who were not bullied at the baseline. Multinomial logistic regression was applied for the analysis under the framework of generalized estimating equations.
Five percent reported onset of workplace bullying within 2 years from the baseline. In confounder-adjusted models, onset of workplace bullying was associated with a higher risk of weight gain of ≥ 1 BMI unit (odds ratio = 1.09; 95% CI: 1.01-1.19) and of ≥ 2.5 BMI units (odds ratio = 1.24; 95% CI: 1.06-1.45). A dose-response pattern was observed, and those exposed to workplace bullying more frequently showed a higher risk (P = 0.04). The association was robust to adjustments, restrictions, stratifications, and use of relative/absolute scales for BMI change.
Participants with exposure to the onset of workplace bullying were more likely to gain weight, a possible pathway linking workplace bullying to increased long-term risk of type 2 diabetes.
本研究旨在探讨职场欺凌的发生作为 BMI 增加的风险因素。
使用来自三个北欧队列研究的重复两年一次的调查数据，共纳入 46148 名年龄在 18 至 65 岁之间、基线时无肥胖且未受欺凌的参与者（67337 名参与者观察）。采用广义估计方程框架下的多变量逻辑回归进行分析。
5%的参与者报告在基线后 2 年内出现职场欺凌。在调整混杂因素后，职场欺凌的发生与体重增加≥1 BMI 单位（比值比=1.09；95%可信区间：1.01-1.19）和增加≥2.5 BMI 单位（比值比=1.24；95%可信区间：1.06-1.45）的风险增加相关。存在剂量反应模式，且频繁遭受职场欺凌的参与者风险更高（P=0.04）。该关联在调整、限制、分层以及 BMI 变化的相对/绝对量表的使用中均具有稳健性。
暴露于职场欺凌发生的参与者更有可能体重增加，这可能是将职场欺凌与 2 型糖尿病长期风险增加联系起来的途径之一。
