Research: Calcium Intake & Mortality

Research Paper Title:

Long Term Calcium Intake and Rates of All Cause and Cardiovascular Mortality: Community Based Prospective Longitudinal Cohort Study.

Study Question:

What is the association of long term intake of dietary and supplemental calcium with mortality from all causes and cardiovascualr disease?

Summary Answer:

High intakes of calcium (>1400 mg/day) are associated with higher mortality from all causes and cardiovascular disease.

What is Known and What this Paper Adds:

A low calcium intake is associated with a higher risk of fracture, stroke, and fatal ischaemic heart disease. Meta-analyses of randomised studies have, however, shown a higher risk of ischaemic heart disease and stroke with use of calcium supplements.

In the swedish cohort  study of women, high intakes of calcium were associated with higher mortality from all causes, cardiovascular disease, and ischaemic heart disease but not from stroke.
