Abstract
Although the main source of dietary calcium is dairy products, the calcium contained in mineral water, which is as available as that of milk, could pr ovide a valuable source of calcium. We analyzed the data from the EPIDOS mu lticenter study to evaluate the relationship between both dietary calcium a nd that supplied by drinking water and bone density measured at the femoral neck by dual-energy X-ray absorptiometry, The study included 4434 women ov er 75 years of age who had not received any treatment likely to interfere w ith calcium metabolism. A significant correlation was found between total c alcium intake and bone density at the femoral neck (r = 0.10, p < 0.001), A fter adjustment for the main variables influencing bone density, an increas e of 100 mg/day in calcium from drinking water was associated to a 0.5% inc rease in femoral bone density, while a similar increase in dietary calcium from other sources only led to a 0.2% increase; however, this difference wa s not significant. The consumption of calcium-rich mineral water may be of interest, especially in older women who consume little calcium from dairy p roducts.
