Hocaoglu E, et al. - Researchers examined if and how serum 25‐hydroxyvitamin D (25(OH)D) levels are associated with the presence and severity of striae gravidarum (SG) in primigravid women. The numerical scoring system of Atwal et al. was used to score striae. Among 91 included primigravid women at the gestational age of 36‐41 weeks, 55 patients (60.5%) had SG and 36 (39.5%) did not. Women with SG had mean serum 25(OH)D level of 17.69 ± 9.81 ng/mL vs 21.18 ± 11.71 ng/mL in women without SG. This study is identified to be the first study demonstrating the link of having normal values of serum 25(OH)D (≥ 30 ng/mL) with a lower risk of having SG than scarce levels (< 20 ng/mL). Therefore, SG could be prevented in primigravid women via managing vitamin D deficiency.
