Strangely the study says there was no association, but their table shows that those having less than 10 nanograms of vitamin D were twice as likely to have a preterm birth. Perhaps it was because the likelihood of finding that result was not statistically significant (p = 0.06 rather than p< 0.02)

BACKGROUND Preterm birth is an important cause of death and developmental disorder in neonates. Vitamin D deficiency has been shown to regulate body inflammatory factor levels that stimulate elevation of uterine contraction hormones, such as prostaglandin, thus causing preterm birth. However, current observations regarding the relationship between vitamin D and preterm birth are inconsistent. We performed a nested case-control study to investigate the effect of vitamin D on preterm birth.
MATERIAL AND METHODS A prospective cohort study included 200 cases of pregnant women in our hospital from May 2013 to May 2015. Blood samples were collected from early, middle, and late stages of pregnancy. Forty-six patients with preterm delivery were compared with age-matched full-term delivery cases (N=92). High performance liquid chromatography-mass spectrometry (HPLC-MS) was used to detect serum levels of 25(OH)D, 25(OH)D2, and 25(OH)D3. Logistic regression was performed to analyze the correlation between 25(OH)D and risk of preterm birth. R
ESULTS No significant difference in age, smoking/drinking, education level, BMI and vitamin D levels was found between the preterm birth group and full-term delivery group. No significant difference was found for vitamin D levels across different stages of pregnancy; no difference in concentration of 25(OH)D related to preterm birth risk was found. After adjusting for potentially confounding factors, serum vitamin D level did not increase the risk of preterm birth.
CONCLUSIONS This study did not found evidence of an increase in preterm birth risk related to vitamin D level during pregnancy.
