ABSTRACT
INTRODUCTION:: Validation of food frequency questionnaires (FFQs) is recommended for accurate measurement of habitual food consumption. We assessed the relative validity of a FFQ in patients coinfected with hepatitis C virus and human immunodeficiency virus. METHODS:: Each patient responded to a FFQ and three 24-hour food recalls. Pearson's correlation and weighted Kappa index analyses were performed to identify the FFQ relative validity and concordance. RESULTS:: De-attenuated correlation coefficients ranged from 0.35 (vitamin B1) to 0.81 (selenium). The concordance index ranged from 0.07 (vitamin C) to 0.51 (calcium). CONCLUSIONS:: The FFQ showed satisfactory relative validity for most nutrients.

INTRODUCTION: Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) coinfection may cause nutrient deficiency and affect the nutritional status.Objetive: To assess nutritional status, and energy and macronutrient intake in HCV/HIV coinfected patients. METHODS: Cross-sectional study on HIV/HCV-coinfected patients treated in a public hospital. Nutritional status was assessed by measurements of weight, height, waist circumference (WC), arm circumference (AC), triceps skinfold thickness (TST), non-dominant hand gripltrength (NDHGS), body mass index (BMI) and mid-upper arm circumference (MUAC). Dietary intake was assessed by 24-hour recall. RESULTS: Fifty-seven patients (59.6% women) with mean age of 46 ± 11.2 years were studied. According to BMI, more than half of patients were overweight or obese, and 41% of men and 68% of women had increased or substantially increased WC. The prevalence of malnutrition varied between the methods -10.5% (BMI), 29.8% (AC), 56.2% (TST), 17.6% (MUAC), and 12.3% (NDHGS). We found a high percentage of patients with inadequate intake of protein, fat and energy. The percentage of total energy intake (%TEI) from carbohydrates inversely correlated with WC and AC. A positive correlation was observed between %TEI from protein and NDHGS, and between %TEI from fat and BMI, WC and AC. CONCLUSION: We found a high prevalence of increased body weight and WC, and inadequate dietary intake in HCV/HIV coinfected patients. We observed a positive association between protein intake and muscle function, and between fat intake and obesity.

Introducción: la coinfección con el virus de la hepatitis C (HCV) y el virus de la inmunodeficiencia humana (HIV) puede comprometer el estado nutricional y causar deficiencia de nutrientes. Objetivo: evaluar el estado nutricional y la ingesta de energía y macronutrientes en pacientes coinfectados por el HCV/HIV (human immunodeficiency virus). Métodos: estudio transversal con pacientes coinfectados por el HCV/HIV de un hospital público. El estado nutricional se evaluó por mediciones de peso, altura, circunferencia de la cintura (CC), circunferencia del brazo (CB), pliegue cutáneo del tríceps (DCT), fuerza de prensión mano no dominante (FAM), índice de masa corporal (IMC) y circunferencia muscular del brazo (CMB). La evaluación del consumo de alimentos se realizó mediante encuesta de recordatorio de 24 horas. Resultados: se evaluaron 57 pacientes (59,6% mujeres) con una edad media de 46 ± 11,2. De acuerdo con el IMC, más de la mitad de los participantes eran obesos o con sobrepeso. Además, el 40,9% de los hombres y el 67,6% de las mujeres tenían CC aumentada. La prevalencia de desnutrición varió entre los métodos: IMC (10,5%), CB (29,8%), DCT (56,2%), CMB (17,6%), FAM (12,3%). Hubo un alto porcentaje de consumo insuficiente de proteínas, lípidos y energía. El porcentaje del valor energético total (%VET) de carbohidratos se asoció inversamente con las medidas de CC y CB. El %VET de proteínas se correlacionó positivamente con las medidas de FAM. El %VET de lípidos mostró una asociación positiva con el IMC, CC y CB. Conclusión: se encontró una alta prevalencia del aumento de peso corporal y CC, y una ingesta dietética inadecuada. Se observó una asociación positiva entre la ingesta de proteínas y la función muscular, y entre la ingesta de grasa y la obesidad (AU)
