The researchers reported that many of the young women had vitamin D levels that were below what is considered sufficient for good health.
All told, 61 percent of the women of color participating had low levels of D, compared to 35 percent of the white women in the study. All the women’s vitamin D levels varied with the time of the year and, as expected, were lowest in winter, rose in the spring and declined in the fall. More than a third of the participants reported clinically significant symptoms of depression each week for the duration of the study.
The lower the women’s levels of vitamin D, the more likely they were to have clinically significant symptoms of depression over the course of the five-week study, even after the investigators accounted for other possible contributing factors, such as time of year, the amount of exercise the women performed and the amount of time they spent outdoors.
Even so, the researchers said that their findings don’t conclusively show that low vitamin D levels were the cause of depression in their subjects. The next step would be a clinical trial to see whether vitamin D supplements can help prevent or relieve depression.
