Key clinical point: Shift work was associated with significantly increased risks for headache and migraine, whereas night shifts only increased the risk for headaches.
Major finding: Shift work was significantly associated with an increased risk for headaches (hazard ratio [HR] 1.32; P < .001) and migraine (HR 1.63; P < .001), with the risk for headaches being further elevated in individuals who worked night shifts (HR 1.44; P = .011).
Study details: Findings are from a meta-analysis of seven cross-sectional studies that included 422,869 participants .
