ABSTRACT

Objective: the objective of this work is to investigate the distribution of underweight, overweight, the general and central obesity in 8-15-year-old Bulgarian children and adolescents, through the use of the anthropometric indices BMI and WHtR.
Materials and Methods: subject of this study are 878 children and adolescents (437 boys and 441 girls) of Smolyan region, Bulgaria, at the age of 8 to 15 years. The study is cross-sectional and was conducted in the period 2012-2014. The body height, weight and waist circumference were measured. In addition, the body mass index (BMI) and waist to height ratio (WHtR) were calculated. Overweight and obesity were defined according to the cut-off points of BMI, recommended of IOTF and developed by Cole e t al. (2000; 2007). The central obesity was defined according to the discriminatory values of 0.500 of WHtR. The collected data were analysed by statistical software packages STATISTICA 10.0 and SPSS 16.
Results: overweight occurs among 18.8 % of the boys and 17.0 % of the girls, and obesity occurs among 7.6 % of boys and 3.7 % of the girls. The underweight are 8.0 % of the boys and 10.4 % of the girls. Central obesity (WHtR . 0.500) occur among average 12.75 % of all investigated children independently of their nutritional status (16.2 % of boys and 9.3 % of girls). With central obesity (WHtR . 0.500) are on average 2.7% of all boys and girls with normal weight (n = 96) and an average 46.82% of all participants with overweight and with obesity (n = 205). With increased health risk (WHtR . 0.500) are total of 2.01% (n=16) of all surveyed children (n = 793) from categories normal weight.
Conclusion: there has been an increase in prevalence of overweight and obesity among Bulgarian children and adolescents from Smolyan region during the over one last decade. The relatively high percentage of underweight children, especially among in group of the girls after puberty. The central obesity, as well as its combination with overweight or general obesity is more frequent in boys than in girls.

RESUMEN

Objetivo: el objetivo de este trabajo es investigar la distribucion de peso insuficiente, demasiado pesado, la obesidad general y central en 8 ninos bulgaros de 15 anos y adolescentes, a traves del uso de los indices antropometricos BMI y WHtR.
Materiales y metodos: el objeto de este estudio son 878 ninos y adolescentes (437 ninos y 441 ninas) de la region de Smolyan, Bulgaria, con edades de 8 a 15 anos. El estudio es transversal y se llevo a cabo en el periodo 2012- 2014. Se miden la altura, el peso y la circunferencia de la cintura, asi como el indice de masa corporal. El sobrepeso y la obesidad se definen de acuerdo con los puntos de corte de BMI, recomendado por la IOTF y desarrollado por Cole et al. (2000:2007). La obesidad central fue definida de acuerdo con los valores discriminatorios de 0,500 de WHtR. Los datos obtenidos fueron analizados por los paquetes de software estadistico STATISTICA 10.0 y SPSS 16.
Resultados: el sobrepeso se produce entre el 18,8% de los chicos y el 17,0% de las ninas, y la obesidad entre el 7,6% de los varones y el 3,7% de las chicas. Presentan bajo peso el 8,0% de los chicos y el 10,4% de las chicas. La obesidad central (RCEst . 0.500) se produce en promedio, en el 12,75% de todos los ninos investigados, independientemente de su estado nutricional (16,2% de los varones y el 9,3% de las chicas). Presentan obesidad central (RCEst . 0.500), en promedio, el 2,7% de todos los ninos y ninas con peso normal (n = 96) y un promedio 46,82% de todos los participantes con sobrepeso y con obesidad (n = 205). Con el aumento de riesgo para la salud (RCEst . 0.500) son total de 2,01% (n = 16) de todos los ninos encuestados (n = 793) de las categorias de peso normal.
Conclusion: se ha producido un aumento de la prevalencia de sobrepeso y obesidad en ninos y adolescentes bulgaros de la region de Smolyan durante mas de una decada. El porcentaje de insuficiencia ponderal entre los ninos, es relativamente alto especialmente entre el grupo de las ninas despues de la pubertad. La obesidad central,así como su combinación con el sobrepeso o la obesidad, es más frecuente en niños que en niñas.
