ABSTRACT

A 90 mujeres con sobrepeso y obesidad del área de atracción del Programa de Atención Integral en Salud, PAIS, se les midió la tasa metabólica basal por calorimetría indirecta y se les evaluó tanto el nivel de actividad física como la ingesta de energía y macronutrientes. Se observó una correlación positiva entre el Indice de Masas Corporal y la tasa metabólica basal de estas mujeres. Aunque se encontró diferencia significativa entre el gasto metabólico basal estimado por la ecuación de Harris-Benedict y el gasto metabólico basal medido por calorimetría indirecta, no se encontró diferencia significativa en el total de energía expedida obtenida por ambos métodos. En estas pacientes con sobrepeso no se encontró diferencia significativa entre el gasto energético total y la ingesta energética diaria obtenida, lo que sugiere un estado de equilibrio energético adaptado a la nueva condición de fisiológica. Según la distribución de macronutrientes fue la grasa la que excedió la recomendación dietética diaria.


A group of 90 women with overweight and obesity, residing in the area covered by the Program for Integral Attention in Health (PAIS) participated in this study. The following measurements were made: basal metabolic rate by indirect calorimetry, level of physical activity and intake of energy and macronutrients. There was a positive correlation between Body Mass Index and the basal metabolic rate for these women. Although a significant difference was found between the average basal metabolic expenditure of the group, as estimated by the Harris-Benedict equation and average basal metabolic expenditure as measured by indirect calorimetry, there was no significant difference between total energy expenditure as estimated by both methods. No significant difference was found between average energy expenditure and average energy intake for these women, suggesting a state of energy balance which is an adaption to the new physiological condition. According to the distribution of macronutrients, fat intake exceeded nutritional recommendations.
