Abstract

Objectives: To investigate the relationships between neck circumference (NC) and components of metabolic syndrome (MS) in subjects with newly detected type 2 diabetes at the National Hospital of Endocrinology. Subjects and methods: A cross-sectional descriptive study on 200 subjects with newly diagnosed type 2 diabetes from February 2022 to July 2022. Measure the anthropometric indices (NC, waist circumference, BMI), evaluate the components of MS (waist circumference, blood pressure, triglycerides, HDL-cholesterol, fasting glucose), and analyze the association. Results: The men/women ratio in the study group was 1.22, and the mean age was 51.1 ± 12.0. The largest age group was from 40 to 59 years old, accounting for 48.5%. The mean NC was 35.5 ± 2.1 cm and 33.9 ± 1.7 cm in the men and the women, respectively, the difference was statistically significant with p-value < 0.05. The mean waist circumference was 81.2 ± 8.0cm and 76.2 ± 6.1 cm in the men and in the women, respectively, the difference was statistically significant with p-value < 0.05. In the men: There was statistically significantly positive correlation between the NC and the waist circumference, systolic blood pressure, fasting plasma glucose and significantly negative correlation between the NC and plasma HDL-Cholesterol with p-value < 0.05, and there no significant correlation between the NC and with diastolic blood pressure and plasma triglyceride. In the women: There was a statistically significantly positive correlation between the NC and waist circumference, plasma triglyceride, fasting plasma glucose and significantly negative correlation between the NC and plasma HDL-Cholesterol with p- value < 0.05, and there was no significant correlation between the NC and systolic blood pressure and diastolic blood pressure. Conclusions: In the patients with newly diagnosed type 2 diabetes there was statistically significant correlation between the NC and most components of MS in both men and women, except for plasma triglyceride and diastolic blood pressure in the former, and systolic blood pressure and diastolic blood pressure in the latter.
