Insights
This study provides neck circumference (NC) percentiles for Turkish children, revealing its significance in obesity evaluation. Neck circumference is a valuable clinical and epidemiological tool for assessing body fat distribution and identifying obesity in pediatric populations.
Area of Science:
- Pediatric endocrinology
- Anthropometry
- Public health
Background:
- Accurate anthropometric data is crucial for monitoring child growth and health.
- Neck circumference (NC) is an emerging indicator of body fat distribution and metabolic health.
- Establishing normative data for NC in diverse populations is essential for clinical application.
Purpose of the Study:
- To establish normative neck circumference (NC) percentiles and mean values for Turkish children.
- To evaluate the clinical and epidemiological utility of NC in assessing obesity.
- To provide reference data for pediatricians and researchers.
Main Methods:
- Cross-sectional screening study involving 5481 Turkish children and adolescents (DAMTCA II).
- Utilized the LMS method to construct smoothed NC percentile curves by age and gender.
- Compared NC with other body fat distribution parameters and analyzed its association with obesity status.
Main Results:
- Smoothed NC percentile curves (3rd-97th) were generated for Turkish children and adolescents.
- NC was significantly higher in boys than girls after age 12.
- NC proved to be an important parameter for defining obesity in children across different age groups (6-18 years).
Conclusions:
- The study successfully provides comprehensive NC percentile and mean values for Turkish children.
- NC is a valuable and significant parameter for obesity evaluation in clinical practice and epidemiological studies.
- These findings contribute to the better understanding and management of childhood obesity in Turkey.
Aim:
To provide neck circumference (NC) percentiles and mean values for Turkish children and to investigate their significance in clinical and epidemiological use.
Methods:
Data were obtained from a cross-sectional screening study; DAMTCA II (Determination of Anthropometric Measurements in Turkish Children and Adolescents) in which 5481 subjects from 17 primary, secondary and high schools were included. NC percentiles were produced using the LMS method, and NC was compared with other parameters which define body fat distribution.
Results:
The smoothed NC curves of 3rd, 5th, 15th, 25th, 50th, 75th, 85th, 90th, 95th and 97th percentiles were constructed by age and gender. The descriptive characteristics of collected data were presented as mean (SD: standard deviation) and median (Min-Max: minimum-maximum) to provide detailed information other than smoothed values. The most prominent finding of this study was that the NC of boys was greater, but not significantly higher, than that of girls until the age of 12 but later a prominent increase in the NC of boys is observed compared with girls. We compared obese and non-obese children in the 6-10, 11-13, 14-18 age groups, NC was found to be an important parameter to define obesity.
Conclusions:
This study provides NC percentiles, means and medians values and analyses their significance in obesity evaluation in clinical practice.
