Background: The determination of glycemia is an essential element for the diagnosis of diabetes or possible glycemic alterations. The body composition and fat distribution are related to this parameter. The neck circumference (NC) is an anthropometric measure that has been used to evaluate the overweight and accumulation of subcutaneous fat in the upper body, regardless of age. It is also a useful tool to predict insulin resistance and other risk factors. This research aimed to study the relationship between the NC and glycemia in adolescents and, thus, to analyze the applicability of this anthropometric measure in the screening of glycemic alterations in this group. Methods: The study population consisted of 600 adolescents aged 10 to 19 years. Data on sex, birth date, NC, fasting blood glucose and stage of sexual maturation was collected. Results: The evolution of sexual maturation generated a significant difference in the NC in both sexes, but not affected glycemia. Thus, the association between NC and glycemia was investigated according to this parameter. Among the pre-pubertal adolescents, the NC was significantly higher among those who had glycemia within borderline values, and the opposite occurred among pubertal adolescents. Among post-pubertal adolescents, NC was similar between the two groups. A negative correlation was found in all adolescents, as well as among those who were in the pubertal and post-pubertal stages of sexual maturation. Differently, adolescents in the pre-pubertal stage showed a positive correlation between the NC and the biochemical parameters. Conclusion: This study showed that the relationship between the NC and glycemia varies according to the stage of sexual maturation. As this maturation factor is rarely considered in the glycemic alteration screening, the use of the NC in this age group is not safe and requires further investigations.

The deficiency of Vitamin D (VD) is widely prevalent worldwide in adults, but many studies show that this deficiency also affects adolescents and may be considered a global public health problem. The VD levels are particularly significant in adolescents since it influences several aspects of growth, development, and puberty. During this phase of life, both girls and boys develop reproductive aspects, and secondary sexual characteristics and the adequate nutritional status appear to be the prerequisite for normal pubertal development. Due to the importance of VD in adolescents, the objective of this study was to investigate the association of the levels of this vitamin with glycemic, lipid, and anthropometric profile and sexual maturation stages of adolescents. Anthropometric (weight and height) and biochemical (fasting glycemia, total cholesterol, HDL-c, LDL-c, and triglycerides) data and VD levels were collected in 67 adolescents. 66% of the adolescents showed VD sufficiency, 28% insufficiency, and 6% showed the deficiency. There was a significant difference in VD levels between the stages of sexual maturation for boys and girls. Overweight patients had lower serum VD levels. The correlation analysis indicated a positive correlation between VD and fasting glycemia and HDL-c, but with no significant difference. A negative correlation was observed between VD and cholesterol, LDL-c and triglycerides, but also with no significant difference. Once VD is crucial for bone health, and as it seems it is necessary to the homeostasis of glycemia, lipids, and body weight, we suggest that more studies should be conducted to confirm the precise role of this vitamin in the promotion and maintenance of health in this population.

The Lipid Accumulation Product (LAP) is a clinical marker of visceral obesity and has been proposed as a simple, inexpensive, and accurate tool to estimate cardiovascular risk and mortality. The aim of this study was to verify the association of LAP with anthropometric, biochemical, visceral adiposity index and IR in adults and the elderly. This single cross-section center clinical study, with experimental, analytical, primary, and observational design, included 210 participants. Anthropometric (Body Mass Index (BMI), Waist Circumference (WC), and Neck Circumference (NC)), LAP, Visceral Adipose Index (VAI), and biochemical parameters (fasting glycemia, insulinemia (to calculate the Homa-IR index), total cholesterol, LDL-c, HDL-c, and triglycerides) were evaluated. The results showed that by separating the sample into three groups (adequate BMI and WC, adequate BMI and elevated WC, and elevated BMI and WC), the group with high BMI and WC showed a high value of LAP and VAI compared to the other groups, with a significant difference. Still, the data show a positive and significant correlation when relating the LAP with VAI, HOMA-IR, BMI, WC, NC, total cholesterol, triglycerides, and Diastolic Blood Pressure. It also showed an inversely proportional relationship when associating LAP with HDL-c (p
