To estimate work impact of headache among migraineurs.
Data were from a U.S. nationwide mailed questionnaire of 193,477 participants in the American Migraine Prevalence and Prevention study. Lost Productive Time (LPT) was the sum of missed hours plus reduced productivity hour equivalents. The cause of LPT was self-reported.
The mean LPT per week was 1.8 hours for headache and 2.8 for all health related causes; 76.5% of the headache-related LPT was explained by reduced performance (ie, presenteeism). The 29% of migraine cases with 11+ headaches-d/mo accounted for 49% of overall LPT; the 19% of those with pain score of 9 to 10 on a 0 to 10 scale accounted for 33% of the overall LPT.
Individuals with frequent and severe headaches account for a disproportionate share of the headache-related LPT.
评估偏头痛患者中头痛对工作的影响。
数据来自美国偏头痛患病率与预防研究中对193,477名参与者进行的全国性邮寄问卷调查。损失的生产时间（LPT）为错过的小时数加上生产力下降小时数的等效值。LPT的原因由参与者自行报告。
头痛导致的每周平均LPT为1.8小时，所有与健康相关原因导致的为2.8小时；76.5%的与头痛相关的LPT是由工作效率降低（即出勤主义）造成的。每月头痛11次及以上的偏头痛病例占29%，却占总体LPT的49%；疼痛评分为9至10分（0至10分制）的患者占19%，占总体LPT的33%。
频繁且严重头痛的个体在与头痛相关的LPT中所占比例过高。
