In order to minimize recall bias in burden estimation, questions about headache yesterday were included in a population-based survey initiated by LIFTING THE BURDEN : The Global Campaign against Headache.
Throughout China, nonrelated respondents aged 18-65 years were randomly sampled from the general population by a door-to-door survey. A validated structured questionnaire included inquiry into occurrence and burden of headache on the preceding day ("headache yesterday").
The participation rate was 94.1%. Of 5041 participants, 286 (5.7%) (male 3.6%, female 7.9%) reported headache yesterday. Age-weighted prevalence of headache yesterday was 4.8% (male 3.0%, female 6.6%). Headache yesterday lasted all day in 36.8%, <1 hour in 14.3% and for a mean of 3.7 ± 3.3 hours in 48.9%. Headache yesterday was moderate to severe in 79.9%; disability such that they could do less than half of what they had expected was reported by 19.9% and such that they could do nothing by a further 7.5% (total 27.4%). Almost three-quarters (71.5%) with headache yesterday took medication to treat it.
Of the adult Chinese population, 1.8% have headache at any one time that is of moderate to severe intensity in 1.4%, and 1.3% lose the equivalent of a whole day to headache-attributed disability every day. In China this means 12.3 million people.
为了最大程度地减少负担评估中的回忆偏倚，LIFTING THE BURDEN：The Global Campaign against Headache 发起的一项基于人群的调查中纳入了有关昨日头痛的问题。
在中国各地，通过挨家挨户的调查，从一般人群中随机抽取年龄在 18-65 岁之间的非亲属受访者。一份经过验证的结构化问卷包括对前一天头痛发作情况和负担的询问（“昨日头痛”）。
参与率为 94.1%。在 5041 名参与者中，286 人（5.7%）（男性 3.6%，女性 7.9%）报告了昨日头痛。昨日头痛的年龄加权患病率为 4.8%（男性 3.0%，女性 6.6%）。昨日头痛持续一整天的占 36.8%，<1 小时的占 14.3%，平均持续 3.7±3.3 小时的占 48.9%。昨日头痛中重度疼痛的占 79.9%；19.9%的人报告因头痛导致残疾，以致只能完成预期工作量的一半以下，另有 7.5%的人完全无法工作（总计 27.4%）。近四分之三（71.5%）有昨日头痛的人服用药物来治疗头痛。
在中国成年人中，有 1.8%的人在任何时候都会出现中度至重度头痛，其中 1.4%的人因头痛导致每天丧失一整天的工作能力。这意味着中国有 1230 万人。
