Zusammenfassung
Hintergrund: Abdominelles Übergewicht ist für das Herzkreislaufsystem gefährlicher als ein erhöhter Gesamtkörperfettanteil bei normalem Taillenumfang. Der Body-Mass-Index (BMI) lässt die abdominelle Fettverteilung unberücksichtigt, im Gegensatz zu Taillenumfang (waist circumference, WC) und TailleGröße-Index (Waist-to-Heigh-Ratio, WHtR).
Ziel der Arbeit: WC- und WHtR-Normwerte für Kinder- und Jugendliche (7–18 Jahre) zu erstellen und die Übereinstimmung zwischen der 90. Perzentile für WHtR mit dem, im Erwachsenenalter gültigen Grenzwert von 0,5 zu prüfen.
Material und Methoden: Daten von 1 015 Kindern (534 Mädchen) gingen in die Berechnung der Normwerte ein (1).
Ergebnis: Der Kappa-Koeffizient belegt eine hohe Übereinstimmung zwischen P90 und 0,5 (0,91 für Jungen/ 0,88 für Mädchen).
Diskussion: Die Studie stellt WCund WHtR-Normwerte für Mädchen und Jungen zwischen 7–18 Jahren bereit und belegt eine hohe Übereinstimmung der 90. Perzentile mit dem Grenzwert von 0,5. Im Vergleich mit existierenden Normwerten zeigen unsere Ergebnisse eine Zunahme des abdominellen Übergewichtes, die jedoch nicht in erhöhten Blutdruckwerten resultiert.
Summary
Background: Overweight and obesity are defined by body mass index (BMI) – a measure in question for not discriminating between fat and fat-free mass without focus on central obesity. However, persons with abdominal obesity are at higher risk for cardiovascular disease than overweight persons with a normal waist circumference.
Objective: Provide WC and WHtR reference values for boys and girls aged 7–18. For WHtR, it was further tested, if the 90th percentile, that defines abdominal obesity, corresponds well with the fix cut-off value of 0.5.
Material and methods: Reference values were calculated on 1 015 children (534 girls) according to the LMS method (1).
Results: There was strong agreement between the 90th percentile and 0.5 (Cohen’s Kappa: 0.91 for boys/ 0.88 for girls). No significant correlation was found between BMI, WC, WHtR, and BP.
Conclusions: This study provides WC and WHtR reference values for children and adolescents aged 7–18. For WHtR, there’s good agreement between the 90th percentile and 0.5. Compared to existing reference values, our results indicate an increase of abdominal obesity. So far, this increase does not result in elevated BP levels.
