Calcium intake and lung cancer risk among female nonsmokers: a report from the Shanghai Women's Health Study.

ABSTRACT:

Background

Calcium has been implicated in carcinogenesis and linked to the risk of several cancers in epidemiologic studies; however, few studies have investigated the association of calcium intake with lung cancer risk, particularly among nonsmokers.

Methods

We evaluated the association of intakes of calcium and related minerals, assessed through a food frequency questionnaire, with lung cancer risk among 71,267 female nonsmokers who were cancer free at baseline in the Shanghai Women's Health Study, a population-based, prospective cohort study. Multivariate Cox regression was used to calculate hazard ratios (HR) and 95% confidence intervals (CI).

Results

During follow-up through December 2009 (median follow-up time: 11.2 years), 428 incident lung cancer cases accrued
