Vitamin D's surprising ties to contraception have been revealed
Let's Dive into Vitamin D and Contraception 💊🧪
Vitamin D plays a crucial role in maintaining the right balance of calcium and phosphorus in our bodies, and it aids in absorbing calcium—a vital component for our bones. Interestingly, many foods like fish and eggs are rich in vitamin D, but about 90 percent of it is produced in our skin when we soak up sunlight.
Deficiency in vitamin D can result in conditions such as rickets and osteomalacia (softening of the bones). Given vitamin D's importance in bone formation, it's particularly crucial during pregnancy.
Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences in Research Triangle Park, NC, set out to investigate whether there's any correlation between vitamin D levels and the use of oral contraceptives.
Vitamin D and Contraception: The Study 🔬
Dr. Harmon and her team carried out a cross-sectional analysis of data from the Study of Environment, Lifestyle, and Fibroids (SELF), a project investigating reproductive health among African-American women aged 23-34 living in and around Detroit, MI. The study questioned women about their contraceptive use, including how much time they spent outside and any vitamin D supplements they took. In total, 1,662 participants provided blood samples to measure the most common circulating form of vitamin D, called 25-hydroxy vitamin D.
The Results: Extremely enlightening! 💡
The study found that women using contraception containing estrogen tended to have higher vitamin D levels compared to others. After accounting for confounding factors such as seasonal exposure to light, the effect remained significant. "We couldn't find any behavioral differences to explain the increase," explained Dr. Harmon. "Our findings suggest that contraceptives containing estrogen tend to boost vitamin D levels, and those levels are likely to drop when women stop using contraception."
After adjusting 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. Current users of birth control had higher vitamin D levels, while past users had average vitamin D levels.
Vitamin D Deficiency in Early Pregnancy: A Concern 🤰
The findings published in the Journal of Clinical Endocrinology & Metabolism imply a risk that women, as they try to become pregnant, might become vitamin D deficient. Dr. Harmon advises caution: "For women planning to stop using birth control, ensuring adequate vitamin D levels before and during pregnancy would be wise."
But...Why the Connection Between Estrogen and Vitamin D? 🤔
Dr. Harmon indicated that further research is necessary to determine why vitamin D levels are increased with the use of estrogen-containing contraceptives. However, other work suggests that the metabolism of vitamin D might be altered when women use estrogen-containing contraception, which could provide some insights.
Lastly, Dr. Harmon noted that the study looked solely at African-American women. While racially specific differences in this association are not explored, she remarked that African-American women in the United States are more likely to be vitamin D deficient, making even small increases or decreases in vitamin D concentrations more significant.
Dr. Harmon will continue tracking the same group of women to delve deeper into the relationship and is working on another group to examine how vitamin D varies across the menstrual cycle.
