SEATTLE, January 21, 2010 (LifeSiteNews.com) - A new study showing a link between long-term use of oral contraceptives and a decrease in bone density in women under the age of 30 has found that the modern low-dose forms of estrogen pills have the greatest risk of harming a woman's bone density.
The study, published in the January issue of Contraception Journal, measured bone mineral density (BMD) of the hip, spine, and whole body to analyze how both the duration of taking the contraceptive pill and the estrogen dose affected bone density in young women.
Researchers studied 606 women, aged 14 to 30, and found a 5.9 percent decrease in bone mineral density of the spine in young women taking birth control pills for longer than one year, as compared with those not taking oral contraceptives. BMD of the whole body was shown to be decreased by 2.3 percent in those taking the pill.
