Up to 10 percent of adults in the developed world suffer from chronic insomnia, and cancer patients are particularly prone to it, researchers note in Sleep Medicine.

在已開發世界，多達10％的成人飽受慢性失眠之苦，癌症患者特別有這種傾向，研究人員在「睡眠醫學期刊」中指出。

For the study, researchers examined data on 405 cancer patients in Germany who were 59 years old on average and completed two assessments of insomnia severity：once when they joined the study and again twelve months later.

針對這項研究，研究人員檢視405名德國癌症患者的資料，其平均年齡為59歲，並完成兩份失眠嚴重程度評估：一次是他們加入該研究時，接著是12個月之後。

At the start of the study, 49 percent of the patients had insomnia symptoms, and 13 percent had severe enough sleep problems to meet the clinical definition of insomnia, the study found. After a year, 64 percent of the patients who started out with insomnia were still suffering from symptoms.
