In this large prospective cohort study, researchers in Norway found that high concentrations of magnesium in drinking water correlated with a lower percentage of hip fractures.
“[In this study] covering two thirds of the Norwegian population and comprising of 19,000 hip fractures, we observed a consistent and significantly reduced risk of hip fractures in both men and women with a relatively high compared to low magnesium concentration in drinking water,” Cecilie Dahl, MPH, and colleagues wrote in the study.
Data consisted of the NORHip database of all hip fractures in Norwegian hospitals from 1994 to 2008 and a survey of trace metals in municipal water from 1986 to 1991. Researchers studied men and women who were 50 years to 85 years old during 1994 to 2000. Parameters, such as urbanization, variations between geographical region, if the water source was ground or surface and the pH of the water, were considered.
Cecilie and colleagues found an increase in urbanization correlated with an increase in hip fractures; however, pH had little effect. The researchers found the association between calcium and hip fracture was less consistent. However, they said calcium may need to be present for magnesium to retain its protective properties.
“Magnesium in drinking water may have a protective role against hip fractures; however, this association should be further investigated,” the researchers state.
