Unveiled connection between vitamin D and contraceptive methods explored
Breaking it Down: Estrogen-Based Birth Control and Vitamin D Levels
Women taking estrogen-based birth control pills are found to have higher quantities of circulating vitamin D, while those who stop using these contraceptives face a significant drop in vitamin D levels. It's crucial to understand the role of vitamin D in maintaining proper calcium and phosphorus levels in the blood and helping the body absorb calcium—an essential component of bones.
Most vitamin D is produced in the skin through a chemical reaction after exposure to sunlight, with foods like fish and eggs being high in this essential nutrient. Unfortunately, around 90% of the population may be vitamin D deficient. Deficiency can lead to rickets and osteomalacia (softening of the bones), and during pregnancy, when increased levels of the active form of vitamin D are crucial for the growth of the fetal skeleton, pregnant women have an increased risk of vitamin D deficiency.
Researchers, led by Dr. Quaker E. Harmon of the National Institutes of Health's National Institute of Environmental Health Sciences, decided to investigate any changes in vitamin D levels associated with taking oral contraceptives. The team conducted a cross-sectional analysis of data from the Study of Environment, Lifestyle, and Fibroids, an investigation of reproductive health, using nearly 1,700 African-American women living in and around Detroit, MI, aged 23-34.
The study asked women about their contraceptive use, including questions about skin exposure to light and any vitamin D supplements they took. In all, 1,662 women provided blood samples to ascertain levels of the most common circulating form of vitamin D, called 25-hydroxy vitamin D.
The researchers discovered that women who used contraception containing estrogen tended to have higher vitamin D levels than other women. This effect remained significant even after controlling for confounding factors, such as seasonal exposure to light. Dr. Harmon and her team could not find any behavioral differences, such as increased time spent outdoors, to explain the increase.
After adjustments for confounding variables, the use of contraceptive pills, patches, or rings containing estrogen was associated with 20 percent higher levels of 25-hydroxy vitamin D. Furthermore, current users of birth control had higher levels of vitamin D, while past users had average vitamin D levels.
With these findings, women who plan to stop using birth control should take steps to ensure adequate vitamin D levels while trying to conceive and during pregnancy. However, the questions remains why estrogen-based contraception might affect vitamin D levels, as further research is needed to understand the biochemical interactions between estrogen, vitamin D, and estrogen-based contraceptives.
It's important to note that the current study looked solely at African-American women, and race may play a role in this effect. Nevertheless, the association between estrogen-based contraceptives and vitamin D levels has been observed in women of different races. In the United States, African-American women are more likely to be vitamin D-deficient, so small increases or decreases in their vitamin D concentrations may be more important.
Dr. Harmon continues to follow this group of women to further investigate the relationship, and she is working on another group of participants to investigate how vitamin D varies across the menstrual cycle.
In summary, estrogen-based birth control may have an impact on vitamin D levels, and women who plan to conceive should be mindful of the potential implications. Further research is needed to uncover the biochemical interactions between estrogen, vitamin D, and estrogen-based contraceptives.As Always, Stay Curious and Healthy! 🎉🎉🩺💊🌞🏥
