La obesidad es un problema de la salud pública que disminuye la esperanza de vida y genera altos costos sociales y económicos. La tendencia ha sido creciente a nivel mundial con un aumento superior al 75% en los últimos años. El objetivo fue relacionar el metabolismo basal con niveles séricos de proteína C reactiva ultrasensible y variables antropométricas en adolescentes. Se trata de un estudio correlacional, con un diseño no experimental. La muestra fue no probabilística, participaron 33 adolescentes, 13 mujeres y 20 hombres entre 12 a 16 años, entre mayo y diciembre de 2018. Se midió el metabolismo basal, actividad física, variables antropométricas y niveles de proteína C reactiva ultrasensible. Los datos fueron analizados con estadística descriptiva e inferencial y se utilizó el coeficiente de correlación lineal de Pearson, con un nivel de significancia <0,05. Se encontró 66,7% de sobrepeso y obesidad, calculado con el índice de masa corporal, (según puntaje Z ≥ 1). El 78,8% de la muestra presentó un porcentaje de grasa corporal elevado, la proteína C reactiva se encontró elevada en el 18,2% de la muestra, con un promedio de 2,0 mg/dl y, la correlación entre el metabolismo basal y la proteína C reactiva ultrasensible obtuvo un valor r=0,18 y un valor p=0,63. Se concluye que en este grupo de adolescentes la correlación entre el metabolismo basal y la proteína C reactiva ultrasensible fue débil, sin embargo, existe una moderada asociación entre el metabolismo basal y el porcentaje de masa magra, reafirmando la importancia de este tejido como un órgano metabólico activo.
Obesity is a public health problem that decreases life expectancy and generates high social and economic costs. The trend has been increasing worldwide with an increase of over 75% in recent years. The objective was to relate the basal metabolism with serum levels of ultrasensitive C-reactive protein and anthropometric variables in adolescent subjects. It is a correlational study, with a non-experimental design. A non-probabilistic sample of 33 adolescents, 13 women and 20 men, between 12 and 16 years old, were evaluated between the months of May to December 2018. Basal metabolism, physical activity, anthropometric variables and levels of ultrasensitive C-reactive protein were measured. The data were analyzed with descriptive and inferential statistics; Pearson's linear correlation coefficient was used, with a level of significance <0.05. A 66.7% of overweight and obesity was found, calculated with the body mass index, (according to Z score ≥ 1). 78.8% of the sample presented a high percentage of body fat, C-reactive protein was found high in 18.2% of the sample, with an average of 2.0 mg/dl and, the correlation between metabolism baseline and the ultrasensitive C-reactive protein obtained a value r = 0.18 and a value p = 0.63. It is concluded that in this group of adolescents the correlation between basal metabolism and ultrasensitive C-reactive protein was weak; however, there is a moderate association between basal metabolism and lean mass percentage, reaffirming the importance of this tissue as an organ active metabolic.
