Two studies: Seniors’ bone health may not improve with increased calcium intake

.

Research conducted in New Zealand and published in The BMJ suggests that increasing calcium intake through supplements or dietary sources is unlikely to lead to better bone health or a lower incidence of fractures in older patients. In the first study—a systematic review and meta-analysis that assessed calcium intake and bone mineral density (BMD)—investigators identified 59 eligible randomized controlled trials, 51 of which studied calcium supplements and 15 of which evaluated dietary sources of calcium (7 included trials studied both calcium supplements and dietary calcium). They concluded that taking calcium supplements or increasing calcium intake from dietary sources is associated with small, non-progressive increases in BMD (1 percent to 2 percent) that are unlikely to result in a clinically significant reduction in fracture risk. The other systematic review, which involved 2 randomized, controlled trials and 44 cohort studies, found that dietary calcium intake is not linked to risk of fracture. Furthermore, the researchers did not find any clinical trial evidence that increasing calcium intake from dietary sources can prevent fractures. An accompanying editorial comments on the research and poses questions regarding current recommendations for calcium intake in seniors.
