RESUMO

INTRODUCTION: In developing countries, protein-energy malnutrition causes 60% of deaths in children < 5 years of age. OBJECTIVE: To evaluate the effect of a ready-to-use supplementary food (RUSF) on moderate acute malnutrition (MAM) in preschool children. METHOD: Clinical trial that included 155 children with MAM (weight/height Z-score > -3 and ≤ -2). Each child received RUSF in the form of biscuits, four per day (250 kcal), for 12 months. The tutor received education on nutrition, health and hygiene. Recovery (weight/height Z-score > -2) at four, six, and 12 months was assessed using intent-to-treat (ITT) and per protocol (PP) analyses. Changes in chronic malnutrition were also analyzed. RESULTS: In the first semester, adequate RUSF consumption was observed in 61% of the children, and in 42% in the second semester. In the ITT analysis, 78% were identified to have recovered, with 38% reaching normal nutritional values; in the PP analysis, > 90% recovered and > 40% reached normal values. Recovery from chronic malnutrition was also observed. CONCLUSIONS: The consumption of RUSF and an educational program reduced MAM.

INTRODUCCIÓN: En países en desarrollo, la desnutrición proteico-energética causa 60 % de las muertes en los niños menores de cinco años. OBJETIVO: Evaluar el efecto de un suplemento alimenticio listo para consumir (SALC) en la desnutrición aguda moderada (DAM) en niños preescolares. MÉTODO: Ensayo clínico que incluyó 155 niños con DAM (puntuación Z de peso/talla [pZ] mayor de −3 y menor o igual a −2). Cada niño recibió SALC en forma de galletas, cuatro por día (250 kcal), durante 12 meses. El tutor recibió educación sobre nutrición, salud e higiene. La recuperación (pZ peso/talla mayor de −2) a los cuatro, seis y 12 meses se evaluó con un análisis por intención a tratar (AIT) y por protocolo (APP). También se analizaron cambios en la desnutrición crónica. RESULTADOS: En el primer semestre se observó consumo adecuado del SALC en 61 % de los niños y en 42 % en el segundo semestre. Con el AIT se identificó que 78 % se recuperó y 38 % alcanzó valores normales de nutrición; con el APP, > 90 % se recuperó y > 40 % alcanzó valores normales. Se observó recuperación de la desnutrición crónica. CONCLUSIONES: El consumo de SALC y un programa educativo redujeron la DAM.

RESUMO

Resumen Introducción: La desnutrición infantil en México alcanza prevalencias de 27.5 % en zonas rurales. Objetivo: Evaluar la efectividad de un suplemento alimenticio listo para consumir (SALC) para corregir desnutrición aguda leve y prevenir desnutrición aguda moderada en preescolares de comunidades rurales. Método: Ensayo clínico aleatorizado por grupos: con y sin SALC (g-SALC y g-S/SALC); se incluyeron niños de dos a cinco años, con puntuaciones-Z de peso para la talla (pZ-P/T) mayor de −2 y menor de −1 y nivel socioeconómico bajo. Todos recibieron educación sobre nutrición, salud e higiene dos veces al mes; los niños del g-SALC debieron consumir diariamente una porción del suplemento. Se evaluó pZ-P/T al inicio y a los cuatro, seis y 12 meses. La comparación entre grupos se realizó con el modelo de riesgos proporcionales de Cox. Resultados: Respecto a la recuperación de desnutrición aguda leve, en g-SALC se observó 68.7 versus 52.1% en el grupo control en el análisis de intención para tratar, con una razón de riesgo (HR) = 1.25; en el análisis por protocolo del primer semestre se observó una HR = 1.48 y en el segundo semestre, HR = 1.56. Un paciente progresó a desnutrición aguda moderada. Conclusiones: El g-SALC mostró resolución significativamente mayor de desnutrición aguda leve.

Abstract Introduction: Child malnutrition in Mexico reaches a prevalence as high as 27.5 % in rural areas. Objective: To assess the effectiveness of a ready-to-use supplementary food (RUSF) to correct mild acute malnutrition and prevent moderate acute malnutrition in preschool children from rural communities. Method: Randomized clinical trial, with assignment to two groups: group with RUSF (RUSF-g) or group without it (non-RUSF-g); children aged from two to five years, with weight-for-height Z-scores (WHZ) between -2 and -1 and low socioeconomic status were included. All received education on nutrition, health and hygiene twice monthly; the RUSF-g children had to consume four biscuits of the supplement every day. WHZ was assessed at baseline and at four, six, and 12 months. The comparison between groups was carried out with Cox proportional hazards model. Results: With regard to mild acute malnutrition correction in the RUSF-g, 68.7 versus 52.1 % in the control group was observed in the intent-to-treat analysis, with a hazard ratio (HR) = 1.25; in the per-protocol analysis of first semester, a HR = 1.48 was observed, and in the second semester, HR = 1.56. One patient progressed to moderate acute malnutrition. Conclusions: The RUSF-g showed a significantly higher resolution of mild acute malnutrition.

RESUMO

BACKGROUND: Ready-to-use supplementary food (RUSF) is increasingly used as a component of food rations for adults with HIV. METHODS: We undertook a qualitative study to evaluate the acceptability and use of peanut-based RUSF compared to corn-soy blend (CSB) among adults living with HIV in rural Haiti who had been enrolled in a prospective, randomized trial comparing the impact of those rations. A total of 13 focus groups were conducted with 84 participants-42 selected from the RUSF arm of the study, and 42 from the CSB arm-using a guide with pre-designated core topics and open-ended questions. RESULTS: We found that RUSF was highly acceptable in terms of taste, preparation, and packaging. Both types of food ration were widely shared inside and outside households, especially with children. However, while CSB was without exception stored with the communal household food supply, RUSF was frequently separated from the household food supply and was more often reserved for consumption by individuals with HIV. CONCLUSIONS: RUSF was a highly acceptable food ration that, compared to CSB, was more often reserved for use by the individual with HIV. Qualitative examination of the perceptions, use, and sharing of food rations is critical to understanding and improving the efficacy of food assistance for food-insecure people living with HIV.

RESUMO

The present study evaluated 20 samples of multimixtures for determining the centesimal and mineral composition. Taking into account the ANVISA Resolution No. 53 that was in force at the time these samples were collected, 55% of samples presented volatile matter content higher than the maximum of 6.0 g%, and only 15% of samples reached the minimum level of 5.5 g% of ashes. All of the analyzed sample showed the maximum level of 15% moisture and volatile matter. These findings are in accordance to the Resolution No 263, in force at present time, in which the unique established parameter has been the limit level of 15% for moisture and volatile substances. The statistic group averages in g% of dry matter varied from 11.42 to 16.10 for protein; from 3.53 to 8.54 for lipids; from 36.41 to 56.65 for carbohydrates, and from 14.66 to 29.76 for dietary fiber. All of analyzed multimixtures might be considered as containing a significant concentration of analyzed minerals, since they reached 30% of recommended daily ingestion (RDI) for children up to 10 years of age as prescribed by ANVISA Decree No 33. However, as multimixture format is equivalent to about 5% of the food intake, the manganese only would be provided at significant concentrations. Nearly 65% of samples were characterized as a source of manganese, as they reached 65% of RDI, while 10% of samples were characterized as having

O presente estudo avaliou 20 amostras de multimisturas quanto à composição centesimal e mineral. Considerando-se a resolução nº 53 da ANVISA, em vigor na época da coleta e análise das amostras, 55% das amostras apresentaram teor de umidade e substâncias voláteis superior ao máximo de 6,0g% e apenas 15% atingiram o teor mínimo de 5,5g% de cinzas. Atualmente, vigora a Resolução n 263 da ANVISA, na qual o único parâmetro estipulado é o limite de 15% para umidade e substâncias voláteis; portanto, as amostras estão de acordo com a nova legislação. As médias dos grupos estatísticos, em g% de massa seca, variaram de 11,42 a 16,10 para proteína; de 3,53 a 8,54 para extrato etéreo; de 36,41 a 56,65 para carboidratos e de 14,66 a 29,76 para fibra alimentar. Foram encontrados altos teores de minerais nas amostras, atingindo 30% das Ingestões Diárias Recomendadas (IDRs) para crianças de até 10 anos, conforme a Portaria n 33 da ANVISA. No entanto, como o acréscimo de multimistura é de cerca de 5% da dieta, apenas o mineral manganês fica caracterizado como fonte por ter atingido 15% da IDR em 65% das amostras e, ainda como alto teor em 10% das amostras por ter apresentado 30% da IDR.
