RESUMO
Objetivo: Conocer la asociación entre síntomas depresivos, índice de masa corporal (IMC) y autopercepción del peso corporal en adolescentes escolares de Bogotá, D.C. (Colombia). Materiales y métodos: Se realizó un estudio analítico transversal en el que participaron estudiantes de colegios públicos. Los síntomas depresivos se cuantificaron con la versión de 10 ítems de la escala de Zung para depresión; el IMC a partir de la toma de peso y talla; y la autopercepción de peso corporal mediante una pregunta con tres opciones de respuesta (0=bajo, normal=1 y alto=2). Se calculó el coeficiente de correlación de Spearman (rs) para estimar las asociaciones. Se aceptaron como significativos valores de rs mayores de 0,300. Resultados: Participaron 321 estudiantes, con edades entre 12 y 18 años, media=14.6 años (DE=1,6); el 64,2 % fueron mujeres. Las puntuaciones para síntomas depresivos se encontraron entre 10 y 36, media=20,6 (DE=4,7), moda=21, mediana=21; los IMC se observaron entre 14,5 y 29,8, media=20,5 (DE=3,0); y la autopercepción del peso fue baja en 15,0 %, normal en 71,0 % y alta en 14,0 %. La correlación entre síntomas depresivos y autopercepción del peso fue rs=-0,019 (p=0,740); entre síntomas depresivos e IMC, rs=0,098 (p=0,079); y entre IMC y autopercepción de peso, rs=0,446 (p<0,001). Conclusiones: El IMC guarda una relación estadísticamente significativa con la autopercepción del peso corporal; sin embargo, los síntomas depresivos son independientes de la autopercepción del peso corporal. Se necesitan más investigaciones con adolescentes escolares colombianos.
Objective: The aim of this study was to know the association among depressive symptoms, Body Mass Index (BMI) and self-perception of body weight in adolescent students at Bogotá, Colombia. Method: A cross-sectional study was designed. A voluntary participation was asked to adolescents of State schools. Depressive symptoms were quantified with a ten-item version of Zung Self-Rating Depression Scale; the BMI was calculated employing weight and height; and the self-perception of weight was evaluated using a question with three option answer (0=low body weight; 1=adequate; 2=high). Spearman's correlation coefficient (rs) was used to estimate the association. Values of rs higher than 0.30 were accepted as significant associations. Results: A group of 321 students participated in the research, with ages between 12 and 18 years old, age mean was 14.6 years old (SD=1.6), 64.2% were girls. Depressive symptom scores were between 10 and 36, mean=20.6 (SD=4.7). BMI were between 14.5 and 29.8, mean=20.5 (SD=3.0). Self-perception of weight scores were: 15% low, 71% adequate and 14% high. Correlation between depressive symptoms and self-perception of the body weight was rs=-0.019 (p=0.740); between depressive symptoms and BMI, rs=-0.098 (p=0.079); and between BMI and self-perception of weight was rs=0.446 (p<0.001). Conclusions: BMI is related to self-perception of body weight, but depressive symptoms do not affect self-perception of body weight. More investigations are needed in Colombian students.
RESUMO
El objetivo fue conocer la confiablidad y la dimensionalidad del AUDIT (Cuestionario de Identificación de los Trastornos debidos al Consumo de Alcohol) (Saunders, Aasland, Babor, De la Fuente & Grant, 1993) en estudiantes de medicina de Bogotá, Colombia. Se diseñó un estudio cuantitativo con una muestra no probabilística de 256 estudiantes mayores de 18 años (media=21,8; DE=2,8) y 60,5% mujeres. Se calculó el coeficiente alfa, el coeficiente omega y la dimensionalidad (análisis factorial confirmatorio). Se observó que el alfa fue 0,792 y la omega, 0,878. Se observaron dos dimensiones que explicaron el 49,4% de la varianza. Se concluye que el cuestionario AUDIT muestra alta confiabilidad, con dos dimensiones y es válido para la identificación de trastornos relacionados con el consumo de alcohol. Se necesitan investigaciones que exploren el desempeño frente a un criterio de referencia.
The aim of the research was to know the reliability and validity of the AUDIT (Alcohol Use Disorders Identification Test) (Saunders, Aasland, Babor, de la Fuente & Grant, 1993) in students of medicine at Bogota, Colombia. A quantitative study was designed which participated a non probabilistic sample of 256 students over 18 years old (mean=21.8; SD=2.8), and 60.5% were female. The coefficient alpha, coefficient omega and dimensionality (confirmatory factor analysis) were estimated. The authors found that Cronbach alpha was 0.792, and McDonald omega, 0.878. It was retained two dimensions that explicated 49.4% of the total variance. It is concluded that in this group of university students, the AUDIT shows high reliability, and is valid for identifying alcohol use disorders. There are needed researches which explore AUDIT performance compares with the gold standard.
RESUMO
INTRODUCTION: An important number of medical students are at Risk of suffering an Eating Behavior Disorder (REBD). However, research has been limited regarding associated variables in Colombian students. OBJECTIVE: To estimate the prevalence and related demographic and psychosocial variables associated to the REBD among medicine students in a university of Bogota, Colombia. METHODOLOGY: Transversal study. Demographic variables, academic performance, level of physical activity, daily cigarette smoking, and abuse of alcohol, personal health and observed stress were quantified. The SCOFF questionnaire was used to quantify REBD. Logistic regression was applied to adjust the associations. RESULTS: 289 students participated with an average age of 21.7 years (SD = 2.8), 63.7% were female students. It was observed that 82 students (28.4%) reported unsuccessful academic performance; 35 of them (12.1%), showed high level of physical activity; 39 (13.5%), reported daily cigarette smoking; 86 (29.8%), abused alcohol; 47 (16.3%), showed poor personal health; 23 (8.0%) high stress level observed; and 59 (20.4% 95% CI 15.8-25.0), REBD. High stress level observed (OR = 5.58; 95% CI 2.08-14.95), female (OR = 2.83; 95% CI 1.35-5.95) and alcohol abuse (OR = 2.18; 95% CI 1.10-4.11) were associated to REBD, after adjusting concerning personal health. CONCLUSIONS: Approximately one out of five medical students reports REBD in a private university of Bogota, Colombia reported REBD. High levels of stress observed, female gender and alcohol abuse are associated to REBD. Further research is necessary.
