Shift work induces stress, disturbs family life and interrupts regular meal schedules. Few studies have addressed the association between shift duties and abnormal eating behavior among hospital nurses.
We tested the hypothesis that shift duties were independent predictors of abnormal eating. Self-administered surveys consisting of socio-demographic data, working pattern, Perceived Organizational Support (POS) questionnaire and the patterns of eating style identified by the Dutch Eating Behavior Questionnaires (DEBQ) were used.
One major acute hospital in one Territory of Hong Kong.
All 662 nurses who worked on a full-time basis in this hospital were invited to join the study and among them, 378 completed surveys were collected with a response rate of 57.1%. The average age was 37.2 years, and 91.5% were female. 67.3 were registered nurses, 17.9% enrolled nurses; and 14.5% were ranked nursing officers or above. 39.1% worked in acute settings (medical wards, intensive care units and emergency departments), and 62.1% of respondents had at least 11 years of clinical experience and 76.2% of respondents had shift duties with 81.9% having at least four shift duties per month. Only 66.7% of respondents had normal body mass index (BMI 18.5-22.9 kg/m2).
Three binary logistic regression analyses were conducted with abnormal emotional, external and restraint DEBQ as outcome variables, respectively. We controlled for age, gender, marital status, work setting (acute vs. non-acute), years of clinical experience, the frequency of shift duties, body mass index, perception of body weight changes in the past 6 months, self-perception of recent overeating and POS.
The proportions of participants having abnormal emotional, external and restraint DEBQ scores were 66.4%, 61.4% and 64.0%, respectively. From multiple regression analysis, nurses having 4 or more shift duties per month were more likely to present with abnormal emotional (adjusted odds ratio aOR 2.91, 95% C.I. 1.57-5.42, p=0.001) and restraint (aOR 3.35, 95% C.I. 1.76-6.38, p<0.001) DEBS scores.
Shift duties were positively associated with abnormal eating behavior among nurses working in hospitals. More health promotional initiatives should be targeted towards hospital nurses whose duties require frequent night shifts to enhance healthy eating.
轮班工作会带来压力，扰乱家庭生活，并打乱正常的用餐时间。很少有研究探讨轮班工作与医院护士异常饮食行为之间的关系。
我们检验了轮班工作是异常饮食的独立预测因素这一假设。使用了自我管理调查，其中包括社会人口统计学数据、工作模式、感知组织支持（POS）问卷以及荷兰饮食行为问卷（DEBQ）确定的饮食模式。
香港特别行政区的一家主要急症医院。
该医院所有全职工作的 662 名护士均被邀请参加研究，其中有 378 名完成了调查，应答率为 57.1%。平均年龄为 37.2 岁，91.5%为女性。67.3%为注册护士，17.9%为注册护士；14.5%为护士长或以上级别。39.1%在急症环境中工作（内科病房、重症监护病房和急诊科），62.1%的受访者有至少 11 年的临床经验，76.2%的受访者有轮班工作，其中 81.9%的人每月至少有 4 次轮班。只有 66.7%的受访者的体重指数正常（BMI 18.5-22.9 kg/m2）。
将异常情绪、外部和抑制 DEBQ 作为因变量，分别进行了 3 项二元逻辑回归分析。我们控制了年龄、性别、婚姻状况、工作地点（急症与非急症）、临床经验年限、轮班频率、体重指数、过去 6 个月体重变化的感知、自我感知最近暴饮暴食以及 POS。
有 66.4%、61.4%和 64.0%的参与者出现异常情绪、外部和抑制 DEBQ 评分。多元回归分析显示，每月有 4 次或以上轮班的护士更有可能出现异常情绪（调整后的优势比 aOR 2.91，95%置信区间 1.57-5.42，p=0.001）和抑制（aOR 3.35，95%置信区间 1.76-6.38，p<0.001）DEBS 评分。
轮班工作与医院护士的异常饮食行为呈正相关。应针对需要频繁夜班的医院护士开展更多的健康促进活动，以促进健康饮食。
