Researchers from Sichuan University (Chengdu, China) have conducted analyses which imply that long-term night shift work among women may be a risk factor for developing certain cancers.
A meta-analysis was performed using data from 61 articles, comprised 114,628 cancer cases and 3,909,152 participants from around the world. The articles consisted of a mixture of study types, including 26 cohort studies, 24 case-controlled studies and 11 nested case-control studies.
The trials were analysed for an association between long-term night shift work and 11 cancer types. Further analysis was conducted to specifically examine the risk of six types of cancer in female nurses who worked night shifts.
