Abstract
BACKGROUND: The aim of the present study was to assess the relationship between neck circumference and gestational diabetes. METHODS: This prospective study was conducted on 372 Iranian pregnant women. The criteria set by the American Diabetes Association through 2 h was used to classify subjects with regard to their gestational diabetes. At the 14-16th weeks of pregnancy, the neck circumference was measured. The maternal and fetal outcomes were measured as well. RESULTS: The adjusted logistic regression revealed that neck circumference was a predictor for gestational diabetes mellitus (OR = 1.20; 95% CI = 1.06, 1.34; P = 0.002). The ROC analysis depicted that the cut-off for neck circumference in indicating gestational diabetes was 34.3 cm, with the sensitivity of 53% and the specificity of 66%. CONCLUSION: The findings of the present study revealed that the neck circumference of ≥34.3 cm can be deemed as a predictor of gestational diabetes in the case of Iranian pregnant women.
