To determine work impact of chronic migraine (CM) versus episodic migraine (EM).
Data were from the 2005 American Migraine Prevalence and Prevention study, a longitudinal population survey of more than 11,000 migraineurs. Lost productive time (LPT) was measured as missed work hours plus reduced productivity hour equivalents.
Those with CM were 19% less likely to be working for pay compared with migraineurs with <or=3 headache-days/month. On average, those with CM lost 4.6 hours/wk from headache compared with 1.1 hours for those with <or=3 headache-days/month. Those with 10 to 14 headache-days/month or with CM accounted for 9.1% of employed migraineurs, 20.8% of work-related LPT, and 35% of the overall lost work time when considering medical leave and unemployment.
The work impact of CM and high frequency EM will be underestimated if employment status is not measured.
确定慢性偏头痛（CM）与阵发性偏头痛（EM）的工作影响。
数据来自于 2005 年美国偏头痛患病率和预防研究，这是一项针对超过 11000 名偏头痛患者的纵向人群调查。损失的生产时间（LPT）被测量为旷工时间加上减少的生产力小时当量。
与每月头痛天数<or=3 的偏头痛患者相比，CM 患者的工作比例低 19%。平均而言，CM 患者每周因头痛而损失 4.6 小时，而每月头痛天数<or=3 的患者则损失 1.1 小时。每月有 10 至 14 天头痛或患有 CM 的患者占偏头痛患者就业人数的 9.1%，占与工作相关的 LPT 的 20.8%，占考虑病假和失业时总损失工作时间的 35%。
如果不测量就业状况，CM 和高频 EM 的工作影响将被低估。
