Waist to height rario narrowest point measure

Subjects and Methods Subjects and MeasurementsДata from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were used in the analysis. The objective of this current study was to compare the fixed 0.5 cut-off and the age- and sex-specific 90th percentile (P90) for WHtR in a representative sample of adolescents from Germany with respect to the prevalence of abdominal obesity and to compare the screening ability of WHtR and BMI to identify hypertensive blood pressure (BP) values. Moreover, there are only a few studies which investigated the sensitivity of this cut-off point to identify obesity or risk of cardiovascular disease (CVD) in children and adolescents. Some studies indicate that the cut-point of WHtR of 0.5 is not ideal for all ages, suggesting the need for age-related references. Although a growing number of studies have supported the use of this cut-off in children and adolescents, a systematic review on WHtR with a cut-off of 0.5 highlighted the need for further studies in children. The WHtR cut-off of 0.5 was established based on studies in adults that investigated the associations between WHtR and metabolic syndrome and cardiovascular comorbidities. The advantage is that population-specific reference tables as well as age- and sex-specific cut-off values are not required, in contrast to obesity definitions based on BMI which are highly age-dependent. Because WHtR is only weakly associated with age, it has been suggested that the same cut-off value of 0.5 could be used across all age groups in children and adolescents. WHtR is receiving increasing attention as a measure of abdominal obesity in children and adolescents that is linked to obesity-related cardiovascular risk in adulthood. In a recent meta-analysis, the waist-to-height ratio (WHtR) has been shown to have higher screening potential for adult cardiometabolic risk than waist circumference. In times of high obesity prevalences, efficient diagnostic tools to identify children and adolescents with unfavorable health risks become more important. However, WHtR is not suitable as a screening tool for hypertensive BP in adolescents. Conclusion: The fixed 0.5 WHtR cut-off can be used in German adolescents to characterize abdominal obesity. WHtR and BMI-for-age had equivalent ability to discriminate hypertensive BP (ROC-AUC < 0.7 sensitivity of the 0.5 cut-off for detecting hypertensive BP < 30%). Results: Agreement between the WHtR cut-offs was very good (Kappa 0.89 for boys 0.81 for girls), and the prevalence of abdominal obesity was slightly higher using P90 (boys 12.0% girls 11.3%) compared to 0.5 (boys 10.7% girls 8.0%). Hypertensive BP was defined as BP exceeding age-, sex- and height-specific 95th percentiles or the adult threshold for hypertension (140/90 mm Hg).

Abdominal obesity was assessed by two WHtR cut-points (P90 0.5). Methods: Between 20, the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) was carried out including 3,492 boys and 3,321 girls aged 11-17 years. Objective: The aim of this study was to compare the fixed 0.5 cut-off and the age- and sex-specific 90th percentile (P90) for waist-to-height ratio (WHtR) in German adolescents with respect to the prevalence of abdominal obesity and to compare the screening ability of WHtR and BMI to identify hypertensive blood pressure (BP) values.
