Abstract
Background: The neck circumference (NC) has been shown to be an accurate index for screening overweight and obesity in children and adolescents.
Aim: To perform a meta-analysis to assess the performance of NC for the assessment of overweight and obesity.
Subjects and methods: Data sources were PubMed and EMBASE up to March 2016. Studies providing measures of diagnostic performance of NC and using body mass index as reference standard were included.
Results: Six eligible studies that evaluated 11 214 children and adolescents aged 6–18 years were included in the meta-analysis. NC showed pooled sensitivity to detect high body mass index of 0.780 (95% confidence interval [CI] = 0.765–0.794), specificity of 0.746 (95% CI = 0.736–0.756) and a diagnostic odds ratio of 17.343 (95% CI = 8.743–34.405).
Conclusions: The NC had moderate diagnostic accuracy for identifying overweight and obesity in children and adolescents.
