Body mass index (BMI) can affect an individual's health. The night shift is a characteristic of the nursing profession, which is associated with an abnormal BMI. However, few studies have investigated the association between BMI and burnout in Chinese nurses. This study examined the association between BMI and burnout among Chinese nurses.
A total of 1863 nurses from 12 tertiary hospitals in Shandong Province of China were selected. BMI was calculated as body weight divided by height squared. The Maslach Burnout Service Inventory General Survey (MBI-GS) was used to measure the level of burnout among nurses. Ordinal logistic regression was used to analyse the association between BMI and burnout.
In this study, the prevalence of normal BMI, underweight, overweight, and obesity was 69.2%, 7.5%, 18.2%, and 5.2%, respectively. The prevalence of high emotional exhaustion, high cynicism, and low personal accomplishment among nurses was 26.1%, 38.7%, and 35.6%, respectively. Nurses who were obese were more likely to have high levels of emotional exhaustion (OR=1.493, 95% CI: 1.011 to 2.206) and cynicism (OR=1.511, 95% CI: 1.014 to 2.253), and nurses who were underweight were more likely to have high levels of cynicism (OR=1.593, 95% CI: 1.137 to 2.232) compared with those who were normal weight.
Obesity was positively associated with emotional exhaustion and cynicism, and being underweight was only positively associated with cynicism among Chinese nurses. Hospital administrators should consider BMI when taking effective measures to reduce burnout among nurses.
体重指数（BMI）会影响个人健康。夜班是护理行业的一个特点，与BMI异常有关。然而，很少有研究调查中国护士的BMI与职业倦怠之间的关联。本研究探讨了中国护士的BMI与职业倦怠之间的关联。
选取了中国山东省12家三级医院的1863名护士。BMI的计算方法为体重除以身高的平方。采用马氏职业倦怠量表通用版（MBI-GS）来测量护士的职业倦怠水平。采用有序逻辑回归分析BMI与职业倦怠之间的关联。
在本研究中，正常BMI、体重过轻、超重和肥胖的患病率分别为69.2%、7.5%、18.2%和5.2%。护士中高情绪耗竭、高玩世不恭和低个人成就感的患病率分别为26.1%、38.7%和35.6%。与体重正常的护士相比，肥胖护士更有可能出现高情绪耗竭（OR=1.493，95%CI：1.011至2.206）和玩世不恭（OR=1.511，95%CI：1.014至2.253），体重过轻的护士更有可能出现高玩世不恭（OR=1.593，95%CI：1.137至2.232）。
在中国护士中，肥胖与情绪耗竭和玩世不恭呈正相关，体重过轻仅与玩世不恭呈正相关。医院管理人员在采取有效措施减少护士职业倦怠时应考虑BMI。
