Coverage and educational actions related to the national vitamin A supplementation program: a study in children from the state of Alagoas / Cobertura e ações educativas no âmbito do programa nacional de suplementação de vitamina A: estudo em crianças do estado de Alagoas

Abstract Objectives: To estimate the coverage of the National Vitamin A Supplementation Program (Programa Nacional de Suplementação de Vitamina A) in children from Alagoas, to identify factors associated with this coverage, and to analyze the adequacy of nutrition education actions. Methods: Household survey involving a representative probabilistic sample of children aged 6 to 59 months from Alagoas and their mothers (n = 509). Coverage was defined by the percentage of children with supplementation records in the last semester. The association between the independent variables (socioeconomic, demographic, and health) and the National Vitamin A Supplementation Program coverage was analyzed based on the prevalence ratio and its 95% CI. The mothers' knowledge of questions related to vitamin A was considered as an indicator of the adequacy of nutrition education actions. Results: Program coverage was 91.9% in children aged 6-11.9 months and 38.6% in children aged 12-59 months. In the adjusted analysis, the factors that were associated with greater coverage were: age between 6-11.9 months (PR = 2.50, 95% CI: 2.10-2.96), living in rural areas (PR = 1.45, 95% CI: 1.20-1.76) and living in a house with ≤ 4 rooms (PR = 1.33, 95% CI: 1.09-1.63). Only 26.1% of the mothers were able to mention some food source of vitamin A and only 19.2% were aware of the consequences of vitamin deficiency for health. Conclusions: The National Vitamin A Supplementation Program coverage is below the targets set by the Ministry of Health (except for children < 12 months). The factors associated with greater coverage indicate an adequate focus of the program. The nutrition education activities have not demonstrated satisfactory results. This information should guide actions to improve the program.

Resumo Objetivos Estimar a cobertura do Programa Nacional de Suplementação de Vitamina A em crianças de Alagoas, identificar fatores associados a essa cobertura e analisar a adequação das ações de educação nutricional. Métodos Inquérito domiciliar que envolveu amostra probabilística representativa das crianças de 6 a 59 meses de Alagoas e suas mães (n = 509). A cobertura foi definida pelo percentual de crianças com registro de suplementação no último semestre. A associação entre as variáveis independentes (socioeconômicas, demográficas e de saúde) e a cobertura do Programa Nacional de Suplementação de Vitamina A foi analisada com base na razão de prevalência e seu IC95%. O conhecimento das mães sobre questões relacionadas à vitamina A foi assumido como indicador da adequação das ações de educação nutricional. Resultados A cobertura do programa foi de 91,9% entre crianças de 6-11,9 meses e de 38,6% entre as de 12-59 meses. Na análise ajustada, os fatores que se associaram à maior cobertura foram ter idade entre 6-11,9 meses (RP = 2,50; IC95%: 2,10-2,96), residir em zona rural (RP = 1,45; IC95%: 1,20-1,76) e morar em domicílio com ≤ 4 cômodos (RP = 1,33; IC95%: 1,09-1,63). Somente 26,1% das mães souberam citar algum alimento fonte de vitamina A e apenas 19,2% conheciam as consequências da deficiência dessa vitamina para a saúde. Conclusões A cobertura do Programa Nacional de Suplementação de Vitamina A encontra-se aquém das metas estabelecidas pelo Ministério da Saúde (exceto para crianças < 12 meses). Os fatores associados à maior cobertura evidenciam adequada focalização do programa. As atividades de educação nutricional não ocorrem de forma satisfatória. Essas informações devem nortear ações de aperfeiçoamento do programa.

Protective Effect of Breastfeeding against Overweight Can Be Detected as Early as the Second Year of Life: A Study of Children from One of the Most Socially-deprived Areas of Brazil.

Millions of children live in Brazil’s semi-arid region, one of the most socially-deprived areas of the country, where undernutrition co-exists with obesity as a consequence of the nutrition transition. There is evidence that childhood obesity predisposes adult obesity and, thus, that obesity should be prevented as early as possible. Some studies have shown that breastfeeding is a protective factor against overweight and obesity while other studies have not found this association. There have been few studies on this association in developing countries and of children below two years of age. The present study aimed to investigate whether children exposed to exclusive breastfeeding for ≥6 months showed a lower prevalence of overweight in the second year of life, based on a probability sample of 2,209 children (aged 12 to 24 months). The dependent variable was overweight, defined as weight-for-length z-scores of >2, based on the WHO 2006 standard while the independent variable was exclusive breastfeeding (≥6 months). The prevalence ratio (PR) and its 95% CI were estimated using Poisson regression with robust adjustment of variance. After adjusting for potential confounding factors (socioeconomic, demographic and health-related variables), children on exclusive breastfeeding for ≥6 months showed a lower prevalence of overweight (5.7% vs 9.1%, PR 0.62, 95% CI 0.45-0.89). It was found that exclusive breastfeeding for six months or more is a protective factor against overweight in children in the second year of life living in the Brazilian semi-arid region.

Evolution of the biochemical profile of children treated or undergoing treatment for moderate or severe stunting: consequences of metabolic programming? / Evolução do perfil bioquímico de crianças tratadas ou em tratamento para déficit estatural moderado ou grave: consequências da programação metabólica?

OBJECTIVE: to evaluate changes in the biochemical profile of children treated or being treated for moderate or severe stunting in a nutrition recovery and education center. METHODS: this was a retrospective longitudinal study of 263 children treated at this center between August of 2008 to August of 2011, aged 1 to 6 years, diagnosed with moderate (z-score of height-for-age [HAZ] < -2) or severe stunting (HAZ < -3). Data were collected on socioeconomic conditions, dietary habits, and biochemical changes, as well as height according to age. RESULTS: the nutritional intervention showed an increase in HAZ of children with moderate (0.51 ± 0.4, p = 0.001) and severe (0.91 ± 0.7, p = 0.001) stunting during the monitoring. Increased levels of insulin-like growth factor 1 (IGF-1) (initial: 71.7 ng/dL; final: 90.4 ng/dL; p = 0.01) were also observed, as well as a reduction in triglycerides (TG) in both severely (initial: 91.8 mg/dL; final: 79.1 mg/dL; p = 0.01) and in moderately malnourished children (initial: 109.2 mg/dL; final 88.7 mg/dL; p = 0.01), and a significant increase in high-density lipoprotein cholesterol HDL-C only in the third year of intervention (initial: 31.4 mg/dL; final: 42.2 mg/dL). The values of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels remained high throughout the treatment (initial: 165.1 mg/dL; final: 163.5 mg/dL and initial: 109.0 mg/dL; final: 107.3 mg/dL, respectively). CONCLUSION: the nutritional treatment for children with short stature was effective in reducing stunting and improving TG and HDL-C after three years of intervention. However, the levels of LDL-C and TC remained high even in treated children. It is therefore speculated that these changes may result from metabolic programming due to malnutrition. .

OBJETIVO: avaliar as mudanças no perfil bioquímico de crianças tratadas ou em tratamento para déficit estatural moderado ou grave em um centro de recuperação e educação nutricional. MÉTODOS: estudo longitudinal retrospectivo com 263 crianças semi-internas no Centro no período de agosto/2008 a agosto/2011, com idade entre 1 e 6 anos e diagnóstico de déficit estatural moderado, escore-Z da altura-para-idade (AIZ) < -2 e grave (AIZ < -3). Foram coletados dados socioeconômicos, dietéticos e bioquímicos e a evolução estatural segundo a idade. RESULTADOS: com a intervenção nutricional observou-se incremento no escore-z das crianças com déficit estatural moderado (0,51 ± 0,4; p = 0,001) e grave (0,91 ± 0,7; p = 0,001) durante o período de acompanhamento. Observou-se, ainda, aumento nos níveis de fator de crescimento insulina-símile (IGF-1) (inicial: 71,7 ng/dL; final: 90,4 ng/dL; p = 0,01), redução nos triglicérides (TG) tanto nas crianças graves (inicial: 91,8 mg/dL; final: 79,1 mg/dL; p = 0,01) como nas moderadamente desnutridas (109,2 mg/dL para 88,7 mg/dL; p = 0,01) e aumento significativo do lipoproteína de alta densidade (HDL-C) apenas no terceiro ano de intervenção (inicial: 31,4 mg/dL; final: 42,2 mg/dL). Os valores de colesterol total (CT) e lipoproteína de baixa densidade (LDL-C) continuaram elevados durante todo o tratamento (inicial: 165,1 mg/dL; final: 163,5 mg/dL e inicial: 109,0 mg/dL; final: 107,3 mg/dL, respectivamente). CONCLUSÃO: o tratamento nutricional para as crianças de baixa estatura mostrou-se eficaz na redução do déficit estatural e dos TG e melhora dos níveis de HDL-C após três anos de intervenção. Porém, os níveis de LDL-C e CT mostraram-se sempre elevados mesmo nas ...

Associação entre desnutrição em crianças moradoras de favelas, estado nutricional materno e fatores socioambientais / Association between malnutrition in children living in favelas, maternal nutritional status, and environmental factors

OBJETIVO: Investigar a associação da desnutrição em crianças residentes em assentamentos subnormais (favelas) de Maceió (AL) com o estado nutricional materno e as condições socioambientais. MÉTODOS: Estudo transversal, envolvendo amostra probabilística de 2.075 mães (18 a 45 anos) e respectivos filhos (4 meses a 6 anos), moradoras nas favelas da cidade de Maceió (AL). Para escolha dos assentamentos, procedeu-se primeiramente a uma análise de clusters para eleger a região administrativa da cidade de Maceió com menor índice de desenvolvimento humano. Após essa análise, a 7ª Região Administrativa foi a designada para o estudo, com seus 23 assentamentos subnormais. Os dados socioeconômicos, demográficos, antropométricos e de saúde materno-infantil foram coletados através de inquérito domiciliar. A estatística analisou a razão de chances de uma criança ser desnutrida, e a regressão univariada foi usada para verificar quais variáveis maternas estariam associadas a essa desnutrição. RESULTADOS: A desnutrição crônica (-2 desvios padrão/altura por idade) esteve presente em 8,6 por cento das crianças e associou-se com idade e escolaridade materna, tipo de residência, número de cômodos, revestimento de piso, origem da água e baixo peso ao nascer (< 2.500 g) em crianças com idade < 24 meses. Encontrou-se também associação entre desnutrição infantil e baixa estatura materna, que não foi observada para índice de massa corporal. CONCLUSÕES: A alta prevalência de desnutrição infantil observada nesses assentamentos esteve relacionada às condições socioambientais e à baixa estatura das mães, que apresentaram déficit ou excesso de peso.

OBJECTIVE: To investigate the association of malnutrition in children living in substandard settlements (slums) of Maceió, AL, Brazil, with maternal nutritional status and environmental conditions. METHODS: Cross-sectional study involving a probability sample of 2,075 mothers (18 to 45 years) and their children (4 months to 6 years), living in the slums of the city of Maceió. First, we conducted a cluster analysis with the purpose of choosing the settlements and the administrative region of the city of Maceió with the lowest human development index. After this analysis, the 7th Administrative Region was designated for the study, including its 23 substandard settlements. Socioeconomic, demographic, anthropometric, and maternal and child health data were collected by means of household survey. The statistical analysis included the odds ratio of a child to be malnourished, and the univariate regression was used to check which maternal variables were associated with this malnutrition. RESULTS: Chronic malnutrition (-2 standard deviations/height for age) was found in 8.6 percent of children and was associated with mother's age and educational level, type of residence, number of rooms, flooring, water supply, and low birth weight (< 2,500 g) in children aged < 24 months. We also found an association between child malnutrition and maternal height. Such association was not observed regarding body mass index. CONCLUSIONS: The high prevalence of malnutrition observed in these settlements was related to social and environmental conditions and short maternal height, who had weight deficit or weight excess.

Short stature and food habits as determining factors for the low productivity of sugarcane labourers in the State of Alagoas, north-eastern Brazil

Undernutrition, especially in the prenatal period and/or until 5 years of age, can cause stunting. Adults with short stature resultant from this process show a series of functional deficits. amongst which is a reduced capacity to do physical work. The aim of this investigationwas to evaluare the dietary pattern, nutritional status and stature of sugarcane cutters, and to determine possible associations with worker productivity. Sixty-two male sugarcane cutters (18-50 y) were selected randomly from a population of 600 workers from a plantation in Alagoas (Brazil), and classified as underweight, normal weight or overweight according to BMI (BMI =21.5, 21.5 to = 25 and >25 kg/m², respectively). Body fat composition (percent) was estimated by electrical biompedance and dietary intake by the direct weighing of food consumed. Whilist the average productivity was 8.13 ton/day,m labourers with normal BMI values were more productive (9.12 ton/day) and ingested significantly (p<0.05) greater amounts of energy (16506.4 kJ/dia) than their underweight (7.48 ± 1.5; 12380.7 ± 4184.1) or overweight (9.12 ± 1.5; 16506.4 ± 6360.0) counterparts, respectively. There were associations (p<0.05) between productivity, stature, energy intake and age. The tallest individuals (= 170 cm) had higher productivity and tended to have a higher energy intake, whilst those with the shortest stature (= 160 cm), had a significantly lower productivity, however ingested a similar quantity of energy, nd tented to have a large accumulation of body fat. Multiple regression analysis indetified stature as the parameter most associated with productivity, independent of age and body fat percentage. Productivity of the tallest individuals. The results emphasise the importance of good nutritional status throughghout life for full development of working productivity

Evolução do estado nutricional de crianças submetidas à internação hospitalar / Evolution of nutritional status in hospitalized children

Objetivo: analisar a evolução do estado nutricional de crianças internadas no Hospital Universitário da UFAL. Metodologia: estudo retrospectivo de 52 crianças (O a 10 anos), que estiveram internadas no Hospital Universitário por mais de 10 dias (fevereiro ajulho de 2002). Comparou-se o estado nutricional, expresso em escore z, do Indice peso para idade (P/I) no momento da admissão (T I) e da alta hospitalar (T 2). Resultados: a faixa etária predominante (44,2por cento) foi a de menor de um ano (mediana= 16,4 meses). O tempo de internação variou de 10 a 77 dias (mediana= 20). A prevalência de desnutrição (DEP) em TI e T2 foi, respectivamente, 71,2por cento e 69,2por cento, mas apenas 15,4por cento tinham esse diagnóstico no prontuário. Neste caso, as crianças sedestacavam das demais pelo extremo grau de magreza e maior T (DEP, n=8: -4,38±2,1, T=30±4,5; DEP não diagnosticado, n=13:-3,13±tO,9,T=23±t18; demais condições,n=31:-0,63±1,1, T=21±13). Das 52 crianças, 29 apresentaram variação de peso positiva, e 23 negativa. No entanto, a magnitude da média dos valores z negativos foi superior à dos valores positivos: -0,56 e 0,50. As crianças com maiores déficits ponderais foram as que permaneceram internadas por maior período de tempo, sem que isso tenha contribuido paramelhorar sua condição nutricional inicial. Conclusão: a prevalência de déficit de peso para idade entre as crianças, no momento da admissão, foi bastante elevada, condição que não se alterou por ocasião da alta hospitalar

The use of protein hydrolysate improves the protein intestinal absorption in undernourished mice infected with Schistosoma mansoni

Patients residing in endemic areas for schistosomiasis in Brazil are usually undernourished and when they develop the hepatosplenic clinical form of the disease should usually receive hospital care, many of them being in need of nutritional rehabilitation before specific treatment can be undertaken. In the mouse model, investigations carried out in our laboratory detected a reduced aminoacid uptake in undernourished animals which is aggravated by a superimposed infection with Schistosoma mansoni. However, in well-nourished infected mice no dysfunction occurs. In this study, we tried to improve the absorptive intestinal performance of undernourished mice infected with S. mansoni by feeding them with hydrolysed casein instead of whole casein. The values obtained for the coefficient of protein intestinal absorption (cpia) among well-nourished mice were above 90 percent (either hydrolysed or whole protein). In undernourished infected mice, however, the cpia improved significantly after feeding them with hydrolysed casein, animals reaching values close to those obtained in well-nourished infected mice

Intestinal protein absorption in malnourished mice with acute schistosomiasis mansoni

Intestinal protein absorption was studied in undernourished albino Swiss mice with acute schistosomiasis mansoni. Undernutrition was induced by feeding mice with the Regional Basic Diet (RBD) ingested by human populations in Northeast Brazil, an experimental model previously developed in our laboratory. Weaning mice were infected with 40 cercariae and compared to undernourished non-infected mice and/or to infected mice fed a balanced control diet. Apparent and True Protein Absorption Coefficients were determined by nitrogen balance during five consecutive days ending at the 63rd day of the trial (acute phase of murine schistosomiasis). Fecal metabolic nitrogen (FMN) was determined after administration of a non-protein diet and was also calculated through linear regression. Our results showed a reduced protein absorption in non-infected RBD-fed mice as compared to mice fed a casein control diet. Infection with Schistosoma mansoni had apparently no effect on intestinal protein absorption in well-nourished mice. However, infection seemed to interfere with protein absorption in under-nourished animals, since the lowest absorption ratios have been detected among RBD-fed infected mice. A brief discussion is made on the advantages of using the method of linear regression for the determination of FMN

Nutrition and acute schistosomiasis

In northeast Brazil, nutritional deficiency diseases and schistosomiasis mansoni overlap. An experimental model, wich reproduces the marasmatic clinical form of protein-energy malnutrition, was developed in this laboratory to study these interactions. Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD) has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis). Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable
