RESUMO

El propósito fue identificar los factores asociados a retraso en el crecimiento en niños de una región semi-rural en Arandas, Jalisco, México. En estudio transversal analítico se incluyeron 432 niños de 12 a 120 meses. Se analizaron variables sociales, demográficas, económicas, dietéticas y patológicas. Se utilizó la puntuación Z del índice talla/edad (< -1 DE y < - 2 DE) para evaluar el déficit de crecimiento. Con la prueba de chi cuadrada y la razón de momios (IC 95 por ciento) se estimaron los factores de riesgo y protección. Los factores de riesgo fueron: > tres niños en la familia [RM 1.71 (1.01, 2.87)], consumo de sodas azucaradas > 4 veces por semana [RM 2.36 (1.19-4.73), ingreso familiar mensual < 200 USA dólares [RM 3.5 (1.28, 9.76)] y gasto per cápita en alimentación < 10 por ciento de un salario mínimo (100 USA dólares al mes) [RM 1.81 (1.06, 3.09)]; edad < 24 meses [RM 2.02 (1.09, 3.75)], adición de azúcar al biberón [RM 8.56 (1.84, 54.9)], modificación de la dieta durante la diarrea [RM 2.40 (1.02, 5.77)] ingestión de leche < 4 veces a la semana [RM 2.71 (1.55, 4.73)] y casi significativo: consumo de frijoles [RM 1.75 (0.98, 3.13)]. Factores de protección: familia nuclear [RM 0.28 (0.09, 0.85)] y dilución adecuada de la fórmula de alimentación [RM 0.71 (0.60, 0.85)]. En el modelo de regresión los factores de riesgo fueron: consumo de sodas, frijoles y adición de azúcar u otros edulcorantes al biberón.

The purpose was to identify risk factors associated to deficit on linear growth in children from a semi-rural population in Arandas, Jalisco, Mexico. In a cross sectional study 432 children, 12 to 120 months old were included. Social, demographic, economical, dietetic and pathological characteristics and deficit in the height /age index (< - 1 and - 2 z score) were considered. A chi square test and Odds Ratio (CI 95 percent) to identify the risk and protection factors were also obtained. Risk factors for height/age deficit were: > 3 children in the family [OR 1.71 (1.01, 2.87)], soft drinks consumption > 4 times a week [OR 2.36 (1.19-4.73)], family’s monthly income < 200 USA dollars [OR 3.5 (1.28, 9.76)] and per capita food expenses < 10 percent of a minimum salary (100 USA dollars a month) [OR 1.81 (1.06, 3.09)]; age < 24 months [OR 2.02 (1.09, 3.75)], adding sweeteners to the bottle [OR 8.56 (1.84, 54.9)], diet modification during diarrhea [OR 2.40 (1.02, 5.77)], milk intake < 4 times a week [OR 2.71 (1.55, 4.73)] and nearly significant, bean consumption [1.75 (0.98, 3.13). Protection factors: nuclear family [OR 0.28 (0.09, 0.85)] and an adequate infant formula dilution [OR 0.71 (0.60, 0.85)]. In multivariate models associated factors to deficit of height were higher consumption of soft drinks, beans and the addition of sweeteners to the bottle. In addition to socioeconomic variables, lower consumption of high quality food and proteins and higher intake of legumes were important risk factors for mild and moderate deficit height/age.

RESUMO

It is not known whether nutritional supplementation in early childhood has long-term benefits on stunted children's mental development. We followed up 127 7-8-y old children who had been stunted in early childhood and received supplementation, stimulation, or both. At 9-24 mo of age, the children had been randomly assigned to four treatment groups: nutritional supplementation, stimulation, both treatments, and control. After 2 y, supplementation and stimulation had independent benefits on the children's development and the effects were additive. The group receiving both treatments caught up to a matched group of 32 nonstunted children. Four years after the end of the 2-y intervention 97% of the children were given a battery of cognitive function, school achievement, and fine motor tests. An additional 52 nonstunted children were included. Factor analyses of the test scores produced three factors: general cognitive, perceptual-motor, and memory. One, the perceptual-motor factor, showed a significant benefit from stimulation, and supplementation benefited only those children whose mothers had higher verbal intelligence quotients. However, each intervention group had higher scores than the control subjects on more tests than would be expected by chance (supplemented and both groups on 14 of 15 tests, P = 0.002; stimulated group in 13 of 15 tests, P = 0.01), suggesting a very small global benefit. There was no longer an additive effect of combined treatments at the end of the intervention. The stunted control group had significantly lower scores than the nonstunted children on most tests. Stunted children's heights and head circumferences on enrollment significantly predicted intelligence quotient at follow-up.

RESUMO

A analise de performance psicomotora dde crianças institucionalizadas é de fundamental importância no planejamento de atividades educativas. Estudos anteriores têm mostrado prejuízos desta funçao em crianças de creches. Objetivo. Comparar o desempenho no teste de triagem de Denver em crianças de 2 a 6 anos de idade, de creches conveniadas com a Prefeitura de Sao Paulo, antes e após seis meses de intervençao nutricional com suplemento alimentar enriquecido com ferro. Método. Foram analisadas 130 crianças de 2 a 6 anos de idade, em três creches municipais de Sao Paulo, aplicando-se o teste de Denver, por psicólogas treinadas, comparando-se os resultados de acordo com o sexo, faixa etaria e estado nutricional, antes e após período de suplementaçao alimentar. Resultados. A maior parte das crianças teve desempenho normal, tanto na primeira aplicaçao (70,80 por cento), como na segunda (80,80 por cento), sem modificaçao do estado nutricional. Na comparaçao dos resultados, 76,92 por cento nao modificaram o desempenho e 18,46 por cento melhoraram significativamente. Em relaçao ao sexo, nao foram encontradas diferenças significantes, enquanto que, para a faixa etaria, houve melhora significante entre as crianças de 4 a 6 anos. Conclusoes. Além do aspecto nutricional, fatores como prontidao para aprendizagem, organizaçao familiar e orientaçao psicopedagógica das creches devem estar favorecendo o desenvolvimento, mesmo considerando-se o baixo nível socioeconomico da populaçao estudada.

RESUMO

UNLABELLED: Psychomotor and development analysis must be emphasized when studying institutionalized children. Many previous investigations have been showing deleterious effects of day care centers over developmental performance in children. OBJECTIVE: This study is aimed at comparing the performance in the Development Screening Test (Denver) in children attending day care centers, before and after nutritional intervention with an energetic supplement enriched with iron. METHOD: 130 children from 2 to 6 years old, attending three municipal day care centers, were evaluated by means of the application of the Denver test; by trained psychologists, comparing the collected data according to sex and age group, before and after six months intervention with iron enriched protein energetic supplement. RESULTS: Most of the children had normal performance, both in first application (70.80%), and in the second one (80.80%). When comparing these results, 76.92% of the children had not altered their performance and 18.46% improved it substantially. As to sex, no significant differences were found and as to age group, there was significant improvement among children aged 4 to 6 years of age. CONCLUSIONS: Besides the nutritional aspects, factors such as learning readiness, family organization, and psychopedagogic orientation to the day care centers, must have fostered development, even if the low socioeconomic level of the studied population is considered.

RESUMO

Con el fin de establecer una curva de crecimiento postnatal para los RNMBP se estudiaron 126 niños alimentados con leche humana. Para el análisis de los resultados se dividieron en tres grupos según el peso de nacimiento. Grupo A (650 a 1000 g), Grupo B (1001 a 1200 g), Grupo C (1201 a 1500 g). Los RN del grupo A perdieron peso hasta el noveno día de vida, los de los grupos B y C hasta el séptimo día. El porcentaje de pérdida de peso alcanzó a 15,7;13,3 y 12,3 respectivamente. Se recuperó el peso de nacimiento a los 25;21 y 20 días; se duplicó cerca de los 70 días y se triplicó después de los 100 días. La talla aumentó 0,66;0,65 y 0,63 cm por semana y el perímetro cefálico 0,81;0,64 y 0,60 por semana en los grupos A, B y C respectivamente, en las primeras 8 semanas. Los resultados parecen indicar que aunque los aumentos de peso, de talla y del perímetro cefálico inicial pueden compararse con lo observado por otros autores, el incremento ponderal después de las dos primeras semanas sería insuficiente, sugiriendo la necesidad de evaluar el uso de leche humana fortificada o fórmulas hipercalóricas en estos pacientes

RESUMO

It has been well established that children suffering from severe or moderate protein energy malnutrition in early childhood show delayed development, but the mechanisms linking undernutrition to poor development are not well understood. One holds that undernutrition causes irreversible central nervous system changes that affect function... The authors have recently reviewed, in detail, studies on activity and undernutrition n children. This work will briefly review the literature on activity levels and behavior in undernourished children and then describe two Jamaican studies that addresses aspects of the functional isolation hypothesis. Activity levels will be discussed first, then, other behaviors (AU)
