Chen SLF, Braaten T, Borch KB, et al. - Women were found to have lower incidence of postmenopausal breast, colorectal, lung, postmenopausal endometrial, pancreatic, and kidney cancer in relation to healthier lifestyle, as evaluated by the healthy lifestyle index (HLI) score, although the magnitude and linearity varied.

• A prospective study with 96,869 women enrolled in the Norwegian Women and Cancer (NOWAC) cohort.

• Five lifestyle factors (physical activity level, BMI, smoking, alcohol intake, and diet) were used to develop HLI.

• For a one-point increment on the HLI score, estimated hazard ratios were 0.97, 0.98, 0.86, 0.93, 0.92, and 0.94 for the above-mentioned malignancies, respectively.

• Nonlinearity was noted for the inverse links between HLI score and the incidence of lung cancer and postmenopausal breast cancer.

• Healthier lifestyle behaviors should essentially be adopted to decrease cancer burden in Norwegian women.
