Increased breast cancer risk among women who work predominantly at night
Authors not listed · 2001
Women who worked at night for at least half a year had an odds ratio of 1.5 (95% confidence interval, 1.2 to 1.7) for breast cancer.
Plain English Summary
Researchers conducted a nationwide population-based case-control study of breast cancer risk among 30- to 54-year-old Danish women who worked predominantly at night. Employment histories were reconstructed back to 1964 for 7035 women with breast cancer and their individually matched controls from a nationwide pension scheme. The odds ratio for breast cancer among women who worked at night for at least half a year was 1.5 (95% confidence interval, 1.2 to 1.7), with a tendency toward higher odds with longer duration of nighttime employment.
Why This Matters
Odds ratios were estimated using conditional logistic regression with a five-year induction period. The analysis adjusted for socio-economic status, age at first and last childbirth, and number of children.
