Prevención de desnutrición aguda moderada con un suplemento alimenticio listo para consumir en niños preescolares de comunidades rurales / Moderate acute malnutrition prevention with a ready-to-use therapeutic food in pre-school children from rural communities

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.

Study causes of chronic energy deficiency of pregnant in the rural areas

Background: Chronic energy deficiency (CED) is one of the malnutrition problems that often occurs in pregnant, caused by lack of energy in a long period of time. One of the effects of pregnant suffering from CED is to increase the risk of maternal and short baby mortality.Method: The study was conducted in 8 villages of Kemranjen Subdistrict, Banyumas, Central Java, Indonesia in 2019. A cross sectional research design with population is that has pregnant. A sample of 130 pregnant was taken incidentally, with inclusion criteria that be able to do interviews and anthropometric measurements, while as the exclusion criterion was that pregnant were suffering from illness that could not be measured.Results: Most of the age was over 30 years and 9.2% suffered from CED. Nutrient intake is mostly less than 80.0% of the nutrition adequacy rate (RDA). The average intake of macro nutrients is 28.05%, the average micronutrient intake is 27.70%. Most graduated were from high school, worked as housewives, consumed supplements, additional food, and added blood tablets and drank milk, suffered from upper respiratory infections (ARI), high blood pressure, and diabetes mellitus, did not get complete immunizations.Conclusion: There were no significant differences in CED based on energy intake (p=1.00), protein intake (p=1.00), fat intake (p=0.179) and carbohydrate intake (p=0.460), work status (p=0.216) and education (p=0.553) and consuming additional food (p=0.225).

Study on the Establishment of Nutrient Requirements for Commercial Supplementary Foods for Infants and Young Children / 대한지역사회영양학회지

This study was conducted to evaluated the nutrition quality of the commercial supplementary foods for infants and young children and to seek a solution to the establishment of standards of nutrient requirements for supplementary foods in Korea. Information on food ingredients, nutrient contents, claims about usefulness of food components and instructions for feeding preparation were obtained from the labels of 33 commercial supplementary foods manufactured by 4 different domestic companies. According to the standard of supplementary foods for infants and young children described in the Korean Food Code, the commercial supplementary foods were categorized into two different types, weaning food and baby food. All the commercial weaning foods were in powder form and mainly composed of cereals, whereas all the baby foods were mainly composed of fruits in the form of canned juice. The weaning foods contained more nutrients than the baby foods did, and the nutrient levels of the weaning foods expressed as nutrient density on energy basis were higher than the RDA for infants aged 5 to 11 months, suggesting that the commercial weaning foods provide adequate amounts of nutrients. If one followed the instructions for feeding preparation appearing on the label, however, recommended amounts of intake of the weaning foods would provide too much energy as well as nutrients. There were many differences in nutrient standards of weaning foods between the Korean Food Code and Codex international food standard. In conclusion, the establishment of standards for nutrient requirements for the supplementary foods requires significant scientific studies on what nutrients are the most inadequate in Korean infants and young children feeds and what levels of nutrients should be added to the foods in order to supplement their nutrition. In addition, it is very important to have a strong scientific basis to support our standard when discrepancies exist between our standard and the international standard.

THE EFFECT OF AN ADDITIONAL MEAL SUPPLEMENTED WITH LYSINE DURING THE BREAK ON THE PHYSICAL DEVELOPMENT OF PRIMARY SCHOOL PUPILS / 营养学报

The physigues of eighty pupils in a primary school in Shanyang were investigated after taking additional L-lysine hydrochloride with meals between classes for 12 weeks. They were derided into 3 groups: 1) ordinary diet plus 0.5g lysine; 2) ordinary diet plus 0.5g lysine and 5 mg iron (lysine and lysine-iron group were referred to as fortified group) and 3) ordinary diet only as control. After 12 weeks of experiment the results showed that the average increase in height, weight and chest measurement of the fortified group was higher than that of the control group, particularly the increase of weight was more remarkable. The increase in subcutaneous fat, however, showed no difference among the three groups, suggesting that weight gain was probably not due to the increase in the subcutaneous fat of the trunks and limbs but to the muscular and other tissues development promoted by the supplementary substances in diet.From a raise in the Hb value and the number of red blood cells in the experimental group, it was proposed that lysine may be good enough for the prevention or treatment of iron dificiency anemia.So that, to supply meals with lysine between classes was considered to be a simple and convenient means for promoting the health of pupils.
