Description
Objetivo: obtener medidas de tendencia central y de dispersión de hemoglobina sanguínea y hematocrito en estudiantesclínicamente sanos de 16 a 35 años, de nuevo ingreso de la Universidad Juárez Autónoma de Tabasco (UJAT), México. Materialesy Métodos: se realizó un estudio descriptivo de corte transversal, en donde a partir de un universo de 3058 sujetos, seexcluyeron 632 por presentar edad fuera del intervalo de estudio, enfermedad clínicamente manifestada, embarazo y/o lugarde origen distinto al Estado de Tabasco, México. Estudiándose una muestra no probabilística de 2426 sujetos clínicamentesanos, a quienes se les registró edad y sexo, y se les realizó biometría hemática. Se determinaron los parámetros normalesde hemoglobina y hematocrito obteniendo la distribución percentilar estratificada por grupos de edad quinquenales y sexo,con 90% de confianza (p=0,1). Resultados: el 50,2% de los sujetos incluidos fueron femeninos y 49,8% masculinos. El grupo deedad predominante fue el de 16-20 años (83,5%) seguido por el de 21-25 años (12,7%), el resto de los grupos no alcanzaronun número suficiente de sujetos para formular conclusiones respecto a los datos obtenidos. Los parámetros normales (P10-P90)para femeninos fueron: 12,10-14,50 g/dL (16-20 años) y 12,30-14,55 g/dL (21-25 años); y para masculinos: 14,20-16,90 g/dL (16-20 años) y 14,30-16,90 g/dL (21-25 años). Conclusiones: los parámetros normales de hemoglobina sanguínea en lossujetos de 16-25 años de esta serie fueron mayores a los parámetros normales conocidos, especialmente en el sexo masculino,demostrándose que existe variabilidad de los parámetros normales de ésta de una región a otra.

Normal parameters of hemoglobin and hematocrit in university students of 16 to 35 years-old from Tabasco, Mexico,2006Objective: To obtain central tendency and dispersion measures of blood hemoglobin and hematocrit in healthy clinicallystudents of 16 to 35 years-old, of new admission to Universidad Juárez Autónoma de Tabasco (UJAT), Mexico. Material andmethods: We achieved a cross-sectional descriptive study, where starting with a universe of 3058 persons was excluded632 for age out study interval, declared clinically disease, pregnancy and/or native State different to Tabasco, Mexico. Westudied a no randomized sample of 2426 healthy clinically persons to who we did register age and gender, and we achievedhematic biometry. We determined hemoglobin and hematocrit normal parameters obtaining percentilar distribution stratifiedby five-years groups and gender with 90% of confidence (p=0,1). Results: 50.2% of persons was females and 49,8% was males.The predominant age group was 16-20 years (83.5%) follow by 21-25 years (12.7%), the remaining groups no obtained a sufficientnumber of persons for we to emit conclusions concerning to obtained information. The normal parameters (P10-P90)for females was: 12,10-14,50 g/dL (16-20 years) and 12,30-14,55 g/dL (21-25 years); and for males: 14,20-16,90 g/dL (16-20years) and 14,30-16,90 g/dL (21-25 years). Conclusions: The hemoglobin normal parameters in 16-25 years-old persons of thisseries was higher to known normal parameters, specially in males, demonstrating the variability of normal parameters of thisvariable of a region to another.
