Al-Mohaissen MA, et al. - Among 345 young Saudi women with normoglycemia and prediabetes, researchers explored the correlation of vitamin D with prediabetes risk and hemoglobin A1c levels. Data of individuals without diabetes (without diabetes history and hemoglobin A1c < 6.4%) from the Princess Nourah bint Abdulrahman University’s non-communicable diseases student registry were analyzed. According to findings, the levels of vitamin D did not predict the prediabetes status and showed no association in this population with levels of hemoglobin A1c. Compared with other well-established risk factors, such as obesity, the impact of vitamin D levels on prediabetes risk may be small.
