Valores hematológicos y bioquímicos y su asociación con el estado nutricional en escolares urbanos de Cuenca, 2012

Abstract

Objective: determine hematological and biochemical values, its relationship to the nutritional status, by age and sex, in schoolchildren in urban of Cuenca city, academic year 2012. Methodology: Analytical Cross-sectional study, 585 students from 5-12 years of age, urban schools Cuenca - Ecuador, academic year 2012-2013. Sample obtained by conglomerates, stratified and randomized using student lists. Responsible students, signed, prior to their inclusion, informed consent and validated instrument respondents. Hematological analyzes were performed and biochemical. Nutritional status was determined using the World Health Organization parameters adjusted by age and sex. Also we compared the laboratory values with the nutritional status. Results: Mean age was 8.87 (SD 1.9), hematological mean values in the students was: RBC= 4.82 x 106/ml (DS 0.31) WBC=7.15 x 103/ml (DS 1.86) Hb= 13.66 g/dL (SD 1.34), Ht= 40.59% (SD 3.92), MCV= 83.64fl (DS 4.03) MCH= 38.31pg (SD 1.27). Mean biochemical values: total serum protein = 6.92g/dL (SD 1.04), serum albumin= 4.37g/dL (DS 0.7), serum iron= 87.40μg/dL (SD 35.31) 19.3% of students showed malnutrition (undernourishment 1.2%, 12.8% overweight and 5.3% obese). There was statistical significant association with the red blood cell and the albumin. Also there was statistical significant differences’ using the t-student with the red blood cell, white blood cell, MCV and hematocrit and iron. Conclusions: there is a high prevalence of overweight and obesity in the scholarship population comparable to the other studies and there was found association between the nutritional status and the hematological and biochemical values.
