Abstract
La obesidad es una enfermedad que puede ser evidenciada mediante el cálculo
del IMC; además, se sugiere determinar el estado nutricional utilizando otras variables
como el porcentaje de grasa ya que este puede diferenciar la masa grasa de la muscular.
Sin embargo, algunos estudios han evidenciado que la relación de estos indicadores puede
diferir según la edad, la etnia y otras características poblacionales. Objetivo: Conocer la
relación entre el Índice de Masa Corporal y el porcentaje de grasa corporal en trabajadores
de una empresa de Lima, durante el periodo 2016 - 2018. Metodología: Se recolectó el
peso y la talla de 109 trabajadores de una empresa peruana del rubro de la minería y
construcción de entre 20 a 70 años y a partir de esta información se determinó su estado
nutricional de acuerdo con la clasificación de la OMS. Además, a través de la
bioimpedancia eléctrica se calculó el porcentaje de grasa corporal, el cual se clasificó de
acuerdo con el criterio de Gallagher. La relación entre estas dos variables se analizó
mediante el coeficiente de correlación Rho de Spearman. Resultados: De la muestra en
estudio se encontró que el 77.1% eran trabajadores del sexo masculino y un 73.4% tenían
edades entre 20 a 39 años. En cuanto al IMC, el 48.6% de los empleados presentan
sobrepeso, el 27.5% normo peso y el 21.1% obesidad 1. Mientras que el 44% contaba con
un porcentaje de grasa corporal normal, el 35.8% elevado y 20.2% muy elevado. La prueba
de correlación Rho de Spearman demostró un coeficiente de 0,599, lo que sugiere una
correlación positiva moderada entre el porcentaje de grasa y el Índice de Masa Corporal.
Conclusión: Existe una relación lineal positiva entre el Índice de Masa Corporal y el
porcentaje de grasa corporal (rs= 0,599; p=0.000).
Obesity is a disease that can be calculated by the BMI; in addition, it is suggested to find the nutritional status using other variables such as the percentage of fat, since this can differentiate fat mass from muscle mass. However, some studies have shown that the relationship of these indicators may differ according to age, ethnicity, and other population characteristics. Objective: To know the relationship between the Body Mass Index and the percentage of body fat in workers of a company in Lima, during the period 2016 - 2018. Methodology: The weight and height of 109 workers of a Peruvian company in the mining and construction sector between 20 and 70 years old were collected and from this information their nutritional status was calculated according to the WHO classification. Likewise, by electrical bioimpedance, the percentage of body fat was calculated, which was classified according to Gallagher's criteria. The relationship between these two variables was analyzed using Spearman's Rho correlation coefficient. Results: Of the study sample, it was found that 77.1% were male workers and 73.4% were between 20 and 39 years old. Considering the BMI, 48.6% of the employees were overweight, 27.5% normal weight and 21.1% obese 1. While 44% had a normal body fat percentage, 35.8% high and 20.2% extremely high. Spearman's Rho confirmation test shows a coefficient of 0.599, suggesting moderate positive confirmation between percentage fat and body mass index. Conclusion: There is a positive linear relationship between the body weight index and the percentage of body fat (Rs= 0.599; p=0.000).
