Mysterious relationship between vitamin D and contraceptive methods exposed
In a fascinating study led by Dr. Quaker E. Harmon from the National Institutes of Health, it's been discovered that women using estrogen-based contraceptive methods, such as pills, patches, or rings, tend to have significantly higher levels of vitamin D. This unexpected find is important, particularly for women planning a pregnancy.
The study, based on data from the Study of Environment, Lifestyle, and Fibroids, analyzed 1,662 African-American women aged 23-34 living near Detroit, MI. The research revealed that current users of estrogen-based contraception had about 20% higher levels of 25-hydroxy vitamin D compared to non-users, even after considering potential confounding factors.
Generally, vitamin D, nicknamed the 'sunshine vitamin,' plays a vital role in maintaining correct calcium and phosphorous levels in the blood and aids the body's absorption of calcium, a crucial component of bones. Most of our vitamin D comes from exposure to sunlight, while foods like fish and eggs also contain decent amounts of the nutrient.
Yet, vitamin D deficiency can lead to health issues such as rickets and osteomalacia (softening of the bones), making it essential, especially during pregnancy. This is because vitamin D is crucial for the formation of bones and maintaining overall health.
However, the specific relationship between estrogen-based contraception and vitamin D is not yet fully understood. Dr. Harmon stated that there may be alterations in the metabolism of vitamin D when women use estrogen-containing contraception. More research is needed to uncover the underlying mechanisms.
While race might not be a determining factor in this association, African-American women are more likely to be at risk of vitamin D deficiency in the United States. Therefore, it's essential for women planning to stop using birth control to ensure adequate vitamin D levels while trying to conceive and during pregnancy.
In the future, Dr. Harmon plans to investigate the relationship further and examine how vitamin D varies across the menstrual cycle in another group of participants. So stay tuned for more on this intriguing study!
