abstract = {Objective: To assess five years trends in total and abdominal fat in Spanish adolescents. 
Design: Two cross-sectional studies: adolescents from the city of Zaragoza (Spain) assessed during 2001-2002 and 2006-2007. 
Subjects: 399 adolescents in 2001-02 and 392 adolescents in 2006-07. 
Main outcome measurements: Socio-economic status was assessed using the education level of both parents. A complete anthropometric assessment was performed in both surveys using the same methodology: weight, height, skinfold thickness (biceps, triceps, subscapular, suprailiac, thigh and calf) and circumferences (waist and hip). The body mass index (BMI) and the sum of 6 skinfold thicknesses were calculated. Body fat percentage (BF%) was also calculated by the formulas described by Slaughter et al. 
Results: After adjusting for age and pubertal status, only females showed a significantly decrease in weight, BMI and waist circumference, and a significant increase in the sum of 6 skinfolds (all P < 0.05 and Cohen's d ≥ 0.25) in 2006-2007, when compared to values obtained in 2001-2002. Males did not show any significant change between the two surveys. Concerning centile values, a slight general reduction was observed in weight, BMI and waist circumference for both males and females. On the contrary, the sum of 6 skinfolds and the BF% were higher in 2006-2007 than in 2001-2002. 
Conclusion: According to these results, there might be a levelling-off in the trends of BMI, BF% and waist circumference in male adolescents from Zaragoza. In females, despite a trend towards higher body fat mass, there was a trend towards lower BMI and waist circumference values.},
abstract = {Objetivo: Evaluar las tendencias de cinco años de la grasa total y abdominal de adolescentes españoles. 
Diseño: Dos estudios transversales: adolescentes de la ciudad de Zaragoza (España) evaluados durante 2001-2002 y 2006-2007. 
Sujetos: 399 adolescentes en 2001-02 y 392 adolescentes en 2006-07. 
Principales variables estudiadas: El estado socioeconómico se evaluó usando el nivel educativo de ambos progenitores. Se realizó una evaluación antropométrica completa en ambos estudios con la misma metodología: peso, talla, grosor del pliegue (bíceps, tríceps, subescapular, suprailíaco, muslo y pantorrilla) y circunferencias (cintura y cadera). Se calcularon el índice de masa corporal (IMC) y la suma del grosor de 6 pliegues. También se calculó el porcentaje de grasa corporal (%GC) con las fórmulas descritas por Slaughter et al. 
Resultados: tras ajustar por edad y estado puberal, sólo las chicas mostraron un descenso significativo del peso, IMC y la circunferencia de la cintura, y un aumento significativo en la suma de los 6 pliegues cutáneos (todos ellos P < 0,05 y d de Cohen ≥ 0,25) en 2006-2007, en comparación con los valores obtenidos en 2001-2002. Los chicos no mostraron cambios significativos entre ambos estudios. Con respecto a los percentiles, se observó una reducción leve del peso, IMC y circunferencia de la cintura en chicos y chicas. Por el contrario, la suma de los 6 pliegues cutáneos y el %GC fueron mayores en 2006-2007 que en 2001-2002. 
Conclusión: de acuerdo con estos resultados, podría haber un resultado neutro en las tendencias del IMC, %GC y circunferencia de la cintura en los adolescentes varones de Zaragoza. En las chicas, a pesar de una mayor tendencia a una mayor grasa corporal, hubo una tendencia a unos menores valores de IMC y de circunferencia de la cintura.},
