ABSTRACT

Introduction: The postprandial stage is associated with the increase of markers related to cardiovascular risk, and its intensity depends on the metabolic state. Objective: To determine the impact of a high-fat meal intake on the metabolic and inflammatory profile, and its relationship to abdominal obesity. Materials and methods: This clinical trial included 42 individuals (21 with abdominal obesity). We measured glucose, insulin, lipid profile, reactive C protein, lipopolysaccharides, and interleukin 6 in fasting blood, and four hours after eating. Results: Besides obesity, we found insulin resistance and higher levels of fasting triacylglycerides and C-reactive protein. There were higher postprandial responses to glucose, insulin, and triacylglycerides. Interleukin 6 decreased in the non-obese group, and lipopolysaccharides increased in both groups. Conclusions: A saturated high-fat food intake produced a greater impact on the glycemic variables in the group with obesity, while it affected the lipids in both groups. However, the increase of triacylglycerides was higher in the presence of a high basal concentration, and it promoted the increase of lipopolysaccharides. The basal and postprandial inflammatory state affected the group with obesity more. The postprandial moment reflected the most frequent state of the individuals on a normal day and evidenced the capacity of the metabolic response to food intake, as well as early metabolic risk states.

ABSTRACT

Resumen Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico. Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal. Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión. Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos. Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

ABSTRACT

Introducción: Los cambios en el estilo de vida y en las demandas en los tipos de trabajo han llevado una mayor tasa de sedentarismo y de tiempo de estar sentado durante el día. Se ha observado que el tiempo que un individuo pasa sentado durante el día está asociado a un incremento en el riesgo de padecer una enfermedad cardiovascular independientemente de la actividad física realizada por el individuo. El objetivo del estudio fue determinar si existe evidencia estadísticamente significativa entre los valores de presión arterial media y de índice de masa corporal entre un grupo de trabajadores de oficina y uno de trabajadores de bodega. Métodos: Estudio prospectivo longitudinal de 200 personas, 100 trabajadores de bodega, 100 de oficina, de diferentes empresas de la Ciudad de Guatemala de 20 a 40 años de edad. Resultados: Se evidenció diferencia estadísticamente significativa entre los valores de presión arterial media (PAM) de los grupos de bodega y oficina (88.03mmHg vs. 89.63mmHg). Los individuos que trabajan en bodega presentaron un mayor índice de masa corporal, el 46% de estos presentaron sobrepeso y el 24% obesidad. Los trabajadores de oficina presentaron un 27% y 12% respectivamente Conclusiones: Existe diferencia entre los valores de IMC y de PAM entre ambos grupos. Respecto al peso, se encontraron mayores valores en el grupo de bodega, el cual pasa menos tiempo sentado, lo cual se considera puede ser resultado de menor nivel de educación y status socioeconómico, lo que lleva a una menor conciencia de la salud y peores elecciones alimentarias entre otros. Palabras Clave: Riesgo cardiovascular, sobrepeso, obesidad, presión arterial, Índice de masa corporal


Introduction: Daily life changes and work demands have lead to a major sedentary life being seating for long periods of time during the day. It has been observed that the time an individual spend seated during the day is associated to an increased risk in cardiovascular disease independent of physical activity. The purpose of this study was to determine if there is statistically significant evidence between mean arterial blood pressure (MABP) and BMI (body mass index) in a group of white and blue collar workers. Methods: This is a prospective longitudinal study with 200 subjects, 100 blue collar workers and 100 white collar workers 20-40 years of age from different businesses in Guatemala City. Results: There was significant difference between BP (88.03mmHg vs. 89.63mmHg) and BMI 46% vs. 27% were overweight and 24% vs.12% were obese between both groups, in which the blue collar workers showed higher values. Conclusion: There is a difference between BMI and mean BP between both groups. We found higher values in the blue collar group, which spend less time seated, and this could be attributed to a lower education level and social status which leads to a lower health awareness and poor food choices among other things. Keywords: cardiovascular risk, overweight, obesity, blood pressure, body mass index
