To determine the relation between body mass index (BMI) and absenteeism.
Data were collected in a prospective cohort study (n = 1284). Multilevel analyses (linear mixed model with random intercept) with two levels (employee and company) were used to test whether BMI was related to duration and frequency of absenteeism and whether this relation was influenced by sports participation.
Obese employees were absent 14 days a year more than normal-weight employees. Also the frequency of absenteeism of more than 7 days was significantly higher. The differences in absenteeism between obese and normal-weight employees were larger for employees who did not practice sport regularly.
Obese employees are more often absent and are absent longer, especially when they do not practice sport regularly. An active company policy to prevent obesity is needed, both from a health and a business efficiency perspective.
确定体重指数（BMI）与旷工之间的关系。
在一项前瞻性队列研究（n = 1284）中收集数据。采用具有两个层次（员工和公司）的多水平分析（带随机截距的线性混合模型）来检验BMI是否与旷工的时长和频率相关，以及这种关系是否受体育活动参与情况的影响。
肥胖员工每年旷工天数比正常体重员工多14天。旷工超过7天的频率也显著更高。对于不经常进行体育活动的员工，肥胖员工与正常体重员工在旷工方面的差异更大。
肥胖员工更常旷工且旷工时间更长，尤其是当他们不经常进行体育活动时。从健康和企业效率的角度来看，都需要制定积极的公司政策来预防肥胖。
