Abstract
Objective

We aim to determine the anthropometric indicator that is most strongly associated with the percentage of body fat and self-regulation of eating behaviour and physical activity among young university students.

Methods

A cross-sectional study was conducted on 3869 Mexican university students, of which 53.9% were women. Standard procedures for anthropometry were followed, including weight, height and waist circumference (WC). This data was used for calculating Body Mass Index (BMI), A Body Shape Index (ABSI), waist-to-height ratio (W/Hr), Body Roundness Index (BRI) and Conicity index (CI). The self-regulation of eating habits scale and the self-regulation of physical activity scale were used. Mean with standard deviation, percentages and Pearson correlation coefficient were estimated.

Results

The group of men shown a higher prevalence of excess weight compared to the women. Inverse correlations between most anthropometric indices and self-regulation of eating behaviour and physical activity were found. However, in all cases the correlations were weak. The percentage of fat had a medium frequency of association with CI and high with BMI, WC, W/Hr and BRI, where the BMI showed the highest correlation coefficient

Conclusions

The BMI shows the highest magnitude of association with percentage of body fat in university students among the indicators analysed. Therefore it is suggested that nurses use BMI to determine obesity because it is easy to calculate.

Resumen
Objetivo

Determinar el indicador antropométrico que presenta mayor fuerza de asociación con el porcentaje de grasa corporal y la autorregulación de alimentación y actividad física en jóvenes estudiantes universitarios, para su uso por personal de enfermería en atención primaria.

Método

Se realizó un estudio transversal en 3869 estudiantes universitarios mexicanos, de los cuales 53.9% fueron mujeres. Se siguieron procedimientos estándar para la antropometría incluyendo peso, talla y circunferencia de cintura (CC). Con estos datos se calcularon índice de masa corporal (IMC), A Body Shape Index (ABSI), índice cintura-talla (ICT), Body roundness index (BRI) y Conicity index (CI). Se aplicaron la Escala de autorregulación de hábitos alimentarios y la Escala de autorregulación de actividad física. Se estimaron medias con desviación estándar, porcentajes y coeficientes de correlación de Pearson.

Resultados

El grupo de hombres presentó prevalencia superior de exceso de peso en comparación con las mujeres. Se encontraron correlaciones inversas entre la mayoría de los índices antropométricos y la autorregulación de hábitos alimentarios y de actividad física, sin embargo, en todos los casos las correlaciones fueron bajas. El porcentaje de grasa corporal tuvo fuerza de asociación media con CI y fuerte con IMC, CC, ICT y BRI, siendo el IMC quien presentó el coeficiente de correlación más fuerte.

Conclusiones

De los indicadores analizados, el IMC muestra la fuerza de asociación más fuerte con el porcentaje de grasa corporal en estudiantes universitarios, por lo que se sugiere mantener su uso en enfermería para la determinación de obesidad por su simplicidad de estimación.
