Validity of self-reported night shift work among women with and without breast cancer

Conclusion This study shows that female breast cancer patients had slightly better recall of previous night shift work than controls. Additionally, both breast cancer patients and controls recalled previous never-night shift work with low specificity. The net effect of this misclassification is a small over-estimation of the relative breast cancer risk due to night shift work. by Vestergaard JM, Haug JND, Dalbøge A, Bonde JPE, Garde AH, Hansen J, Hansen ÅM, Larsen AD, Härmä M, Costello S, Kolstad HA. doi:10.5271/sjweh.4146
