Introduction: Neck Circumference (NC) has been pointed out as an important indicator in the evaluation of overweight and may be useful to determine the level of obesity and metabolic alterations.
Objective: To verify the relationship between the NC and the lipid profile in adolescents with overweight or obesity.
Methods: A cross-sectional study with adolescents between 10 and 19 years old, of both sexes attended at the Endocrinology pediatric Unit in the Northeastern region of Brazil. The anthropometric nutritional status was classified according to World Health Organization reference curves (WHO). For evaluation of NC, it was used as cutoff point adapted for adolescents values >32 cm for females and >35.5 cm for males. Total cholesterol, LDL-c, HDL-c, and triglycerides, were evaluated and classified according to the V Brazilian Guidelines on Dyslipidemias and Prevention of atherosclerosis (2017). Data were analyzed by the Software R x64 3.4.2. Statistical descriptive analysis and Pearson correlation were performed with adopted significance level of P<0.05.
Results: A total of 67 adolescents were evaluated, 52.2% of whom were male. From this sample, 20.9% individuals had overweight, 61.2% with obesity and 17.9% with severe obesity. It was observed that, of the total, 74.6% of the adolescents had elevated total cholesterol and 59.7% of the LDL-c, as well as 70.1% of the adolescents presented HDL-c below the recommendations. Girls presented higher mean values for total cholesterol 172 mg/dl (±28.32), LDL-c 106.81 mg/dl (±21.62), HDL-c 40.16 mg/dl (±7.74) and triglycerides 131.97 mg/dl (±67.79), with no significant difference between genders. 59.3% of the adolescents presented values above the cutoff point for NC. There was a negative correlation between NC and HDL-c (P≤0.01) in males.
Conclusion: Adolescents presented high frequency of changes in total cholesterol, LDL-c and HDL-c, and there was a negative correlation between neck circumference and HDL-c in male adolescents.
