Abstract Introduction: cystic fibrosis is a disease that causes inflammation, oxidative stress and metabolic changes that lead to nutrient deficiency, such as vitamin D deficiency. On the other hand, it is suggested that vitamin D has anti-inflammatory and antioxidant actions. Objective: to evaluate the prevalence of hypovitaminosis D and the association between serum 25 hydroxyvitamin D levels with markers of oxidative stress and inflammation in patients with cystic fibrosis. Method: a cross-sectional study was carried out with 48 patients with cystic fibrosis including children, adolescents and adults in the northeast region of Brazil. Blood collection was performed for analysis of 25-hydroxyvitamin D, calcium, parathyroid hormone, inflammatory process (C-reactive protein [CRP] and alpha-1-acid glycoprotein-A1 [A1GPA]) and oxidative stress (malondialdehyde (MDA) and total antioxidant capacity [CAOT]). The statistical analysis was performed using the "Statistical Package for the Social Sciences", adopting a significance level of p < 0.05. Results: vitamin D insufficiency/deficiency was found in 64.6 % of patients. After multiple linear regression analysis, MDA showed an inverse association with blood values of 25-hydroxyvitamin D (p < 0.05) conditioned by the presence of inflammatory process markers. When only oxidative stress was evaluated, this association disappeared. Conclusion: in conclusion, there was a high prevalence of hypovitaminosis D, with 25(OH)D levels associated with greater oxidative stress when combined with inflammatory markers. Improved vitamin D levels may be an alternative to reduce the damage caused by excess oxidative stress and inflammation in CF patients.

Resumen Introducción: la fibrosis quística es una enfermedad que cursa con inflamación, estrés oxidativo y cambios metabólicos que conducen a deficiencia de nutrientes como la vitamina D. Por otro lado, se sugiere que la vitamina D tiene acción antiinflamatoria y antioxidante. Objetivo: evaluar la prevalencia de hipovitaminosis D y la asociación entre los niveles séricos de 25 hidroxivitamina D con los marcadores de estrés oxidativo e inflamación en pacientes con fibrosis quística. Método: estudio transversal realizado con 48 pacientes con fibrosis quística, niños, adolescentes y adultos, de la región nordeste de Brasil. Se realizó una extracción de sangre para el análisis de 25-hidroxivitamina D, calcio, hormona paratiroidea, proceso inflamatorio (proteína C-reactiva [PCR] y alfa-1-glucoproteína ácida-A1 [A1GPA]) y estrés oxidativo (malondialdehído [MDA] y capacidad antioxidante total [CAOT]). El análisis estadístico se realizó utilizando el "Paquete Estadístico para las Ciencias Sociales", adoptando un nivel de significancia de p < 0,05. Resultados: se encontró insuficiencia/deficiencia de vitamina D en el 64,6 % de los pacientes. Después de un análisis de regresión lineal múltiple, la MDA mostró una asociación inversa con los valores sanguíneos de 25-hidroxivitamina D (p < 0,05) condicionado a la presencia de marcadores de proceso inflamatorio; cuando solo se evalúa el estrés oxidativo, esta asociación desaparece. Conclusión: en conclusión, hubo una alta prevalencia de hipovitaminosis D, con niveles de 25(OH)D asociados a mayor estrés oxidativo cuando se combina con marcadores inflamatorios. La mejora de los niveles de vitamina D puede ser una alternativa para reducir el daño causado por el exceso de estrés oxidativo y la inflamación en pacientes con FQ.

ABSTRACT Objective: To analyze different anatomical sites in the abdominal region, in order to determine the positional parameter that identifies a higher level of visceral adipose tissue (VAT) and confers a greater cardiometabolic risk. Materials and methods: This is a methodological study in which VAT was evaluated by ultrasonography (USG) in three anatomical sites in the abdomen, while the abdominal circumference (AC) was measured using seven different protocols. Additionally, the glycemic and lipid profile, C-reactive protein, and the presence of systemic arterial hypertension were evaluated. Results: One hundred and six individuals with an average age of 42 (36.8-46.2) years were included. The evaluation of the calibration of the ultrasound procedure for the analysis of VAT by intra- and inter-evaluators showed high reproducibility. The pattern of abdominal fat distribution differed between sexes, with higher mean VAT in males (p < 0.05) and higher mean SAT (subcutaneous adipose tissue) in females (p < 0.005). In the abdominal scan applied to women, higher levels of VAT and lower levels of SAT were observed in the narrower waist region, between the iliac crest and the last rib (p < 0.001). In males, the profile of adipose disposition along the abdomen was uniform (p > 0.05). Correlations between VAT measured by USG and cardiometabolic parameters were relatively stronger in the upper abdomen (p < 0.05). Conclusion: Women accumulate more VAT in the narrower waist region, while men accumulate VAT uniformly across the abdomen. There was relative superiority in predicting cardiometabolic risk in the upper abdomen for both sexes.

ABSTRACT Objective: There is no consensus as to the best criterion for the evaluation of metabolic syndrome (MS), impairing the estimation of its prevalence. This study aims to compare MS estimates using three recommended definitions for adolescents based on a cross-sectional study nested in the Consortium of Brazilian Birth Cohorts in São Luís, Maranhão. Subjects and methods: A total of 2,515 adolescents aged between 18 and 19 years were evaluated. The criteria of International Diabetes Federation (IDF) and National Cholesterol Education Program Panel III (NCEP-ATP) modified by Cook and cols. (2003) and De Ferranti and cols. (2004) defined SM. To compare the estimates of MS prevalence, the chi-square, Fisher’s exact and Cohen’s Kappa index tests were used. Results: Among the 2,064 participants evaluated in the final sample. The prevalence of MS ranged from 4.2% (95% CI: 3.3-5.1) to 10.2% (95% CI: 8.8-11.4). When comparing the estimates of MS prevalence in the total sample and by sex, a statistically significant difference was observed. The agreement between the criteria ranged from 0.42 (CI 95%: 0.35-0.49) to 0.55 (CI 95%: 0.48-0.62) in the total sample, 0.33 (CI 95%: 0.24-0.42) to 0.59 (95%CI: 0.47-0.71) among boys and 0.39 (95% CI: 0.26-0.52) to 0.54 (95% CI: 0.44-0.64) among girls. Conclusion: Different criteria provide different estimates for the prevalence of MS in adolescents, reflecting the importance of establishing a consensus.

ABSTRACT Objective To identify the association between dietary patterns and nutritional status in adolescent freshmen at a public university in Northeastern Brazil. Methods In this cross-sectional study anthropometric variables, body composition and food intake were collected and assessed using the food frequency questionnaire. Dietary patterns were evaluated through factor analysis using the principal component extraction method. Results Two dietary patterns were identified: “Western” pattern, consisting of foods with high energy density and low nutritional value, and the “traditional Brazilian” pattern, with foods from Brazilian cuisine such as rice, beans, corn, roots and tubers, fruits, greens and vegetables. The multiple regression analysis revealed a negative association between the “traditional Brazilian” pattern and both excess weight and body fat in females. Conclusion A healthy dietary pattern with typical local cuisine foods can offer protection to health and should be encouraged.

Abstract Objective To analyze the components of Metabolic Syndrome (MetS) and the rationale for adopting the criteria used for its classification in older individuals through an integrative review. Method an integrative review of the literature in Portuguese, English, Spanish and Bulgarian involving older people (age ≥60 years) on the electronic databases MEDLINE - via PubMed, Embase, Web of Science and Scopus, without restriction on publication date or study design, was conducted from August 2022 to January 2023. The Medical Subject Headings (MeSH) and Health Sciences Descriptors (DEcS) controlled descriptors “elderly”, “elderly 80 or older”, “metabolic syndrome”, “prevalence”, “component” and “criterion” were used. Studies that were off-topic, unavailable in full and that failed to answer the guiding question were excluded. Results Application of the eligibility criteria led to the retrieval of 1340 studies, of which 14 were included in the integrative review. Seven sets of criteria were identified for evaluating MetS in the older population were identified and most studies used two of these criteria. The IDF criterion was cited 7 times and the NCEP - ATP III criterion 8 times in the 14 article reviewed. Conclusions Although the searches retrieved different studies on the subject, the results suggest the criteria for MetS should be revised, with cut-off points defined according to the population studied.

RESUMO Objetivo Avaliar o crescimento linear e o ganho de peso de lactentes com suspeita de alergia à proteína do leite de vaca, com manifestações gastrointestinais, atendidos em um ambulatório de gastropediatria. Métodos Estudo de coorte retrospectivo, com informações demográficas, clínicas, antropométricas e dietéticas de 84 lactentes que iniciaram atendimento entre 2015 e 2018 e foram acompanhados durante seis meses. Foram avaliados os índices estatura/idade, peso/idade e índice de massa corporal/idade em escore-z, segundo os pontos de corte da Organização Mundial de Saúde de 2006. Considerou-se crescimento acelerado (ou catch-up growth) um ganho ?0,67 escore-z nos referidos índices, avaliados em três e seis meses. Resultados No baseline, a mediana de idade foi 4,0 meses e 88,1% dos lactentes já estavam em dieta de exclusão. A frequência de baixa estatura foi de 15,5% e a de baixo peso foi de 8,3% e de 3,6% segundo os índices peso/idade e índice de massa corporal/idade, respectivamente. Houve elevado crescimento de recuperação durante o período de acompanhamento, mas que não configurou catch up. Nos meninos, ganhos no peso/idade e índice de massa corporal/idade foram significantes (p=0,02 e p=0,01) e próximos do limiar que caracteriza catch up: 0,58 e 0,59, respectivamente. Nas meninas, foram observados ganhos significantes na estatura/idade e peso/idade, de 0,38 e 0,37 (p=0,02 para ambos). Conclusão Demonstrou-se que lactentes com suspeita de alergia à proteína do leite de vaca, com manifestações gastrointestinais, deveriam ter acesso precoce ao aconselhamento nutricional para evitar exposição ao alimento alergênico, controlar sintomas e, assim, evitar a desnutrição ou garantir recuperação nutricional adequada.

ABSTRACT Objective To assess linear growth and weight gain in infants with suspected cow’s milk protein allergy with gastrointestinal manifestations, seen at a gastropediatrics clinic. Methods A retrospective cohort study conducted with demographic, clinical, anthropometric and dietary information on 84 infants first seen between 2015 and 2018 and followed-up for six months. Stature-for-age, weight-for-age, and body mass index-for-age in z-scores were evaluated according to the cut off points established by the World Health Organization in 2006. Accelerated growth or catch-up was considered a gain ?0.67 in the z-score of the referred indices, evaluated at 3 and 6 months. Results Median age at baseline was 4.0 months and 88.1% of the infants were already in diet exclusion. Regarding the anthropometric evaluation short stature frequency was 15.5% and the underweight frequency was 8.3% and 3.6% respectively based on the weight-for-age and body mass index-for-age indices. High recovery growth was observed during the follow-up period but was not considered catch up. In boys, the gains in weight-for-age and body mass index-for-age were significant (p=0.02 and p=0.01 respectively) and close to the threshold that characterizes the catch up, 0.58 and 0.59, respectively. In girls, significant gains in stature-for-age and weight-for-age (0.38 and 0.37 respectively, p=0.02 for both) were observed. Conclusion Infants with suspected cow’s milk protein allergy with gastrointestinal manifestations should have early access to specialized nutritional counseling to avoid exposure to allergenic food and control allergy symptoms, thereby avoiding malnutrition and ensuring adequate nutritional recovery.

Resumo Em razão de a obesidade ter alcançado proporções epidêmicas e dado ao atual reconhecimento da adiposidade central como um importante fator de risco cardiometabólico, diversos pesquisadores têm se dedicado em desenvolver e validar índices e equações preditivas para avaliar o Tecido Adiposo Visceral (TAV). Este estudo avaliou a aplicabilidade do Índice de Adiposidade Visceral (IAV) como preditor de risco cardiometabólico em indivíduos atendidos em um hospital no nordeste brasileiro. O TAV foi avaliado por tomografia computadorizada (TC) e o IAV foi calculado através de equações específicas para cada sexo. A amostra envolveu pacientes adultos e idosos de ambos os sexos acompanhados no ambulatório de cardiologia. Os seguintes parâmetros cardiometabólicos foram coletados: glicemia de jejum, hemoglobina glicada, perfil lipídico, proteína C-reativa e ácido úrico. Regressão linear simples foi empregada para avaliar o poder explicativo do IAV em relação ao volume de TAV determinado por TC. A capacidade preditiva do IAV em relação ao volume de TAV determinado pela TC foi de 25,8% (p=0,004) para o sexo masculino e 19,9% (p<0,001) para o sexo feminino. O IAV se correlacionou fortemente com as variáveis TG (r=0,916, p< 0,001) e TG/HDL (r=0,952, p<0,001) e inversamente com o HDL (r=-0,441, p<0,001), além disso, apresentou baixa correlação com as variáveis: circunferência abdominal, colesterol total, lipoproteína de baixa densidade, glicemia de jejum e hemoglobina glicada (p<0,05). O IAV associou-se com variáveis consideradas fatores de risco cardiometabólico, porém exibiu baixa capacidade preditiva em relação ao volume de TAV determinado pela TC, sendo recomendada cautela em sua utilização em indivíduos brasileiros.

Abstract As obesity has reached epidemic proportions and given the current recognition of central adiposity as an important cardiometabolic risk factor, several researchers have focused on developing and validating predictive indexes and equations to evaluate Visceral Adipose Tissue (VAT). This study evaluates the applicability of the Visceral Adiposity Index (VAI) for predicting cardiometabolic risk in individuals treated in a hospital In the northeast region of Brazil. The VAT was evaluated by computed tomography (CT) and the VAI was calculated through specific equations for each gender. The sample involved adult and elderly patients of both genders followed up in a cardiology outpatient clinic. The following cardiometabolic parameters were collected: fasting glycemia, glycated hemoglobin, lipid profile, C-reactive protein (CRP) and uric acid. The simple linear regression was used to evaluate the explanatory power of the VAI in relation to the volume of VAT determined by CT. The predictive capacity of VAI in relation to the volume of VAT determined by CT was 25.8% (p=0.004) for males and 19.9% (p<0.001) for females. VAI correlated strongly with the triglyceride (TG) (p<0.001) and TG/high-density lipoprotein (HDL) ratio (p<0.001) and inversely correlated with HDL (p<0.001). Moreover, VAI showed low correlation with the following variables: abdominal circumference, total cholesterol, low density lipoprotein, fasting glycemia, and glycated hemoglobin (p<0.05). VAI was associated with variables considered as cardiometabolic risk factors, but exhibited a low predictive capacity regarding the volume of VAT determined by CT. Thus, caution is recommended in its use in Brazilian individuals.

ABSTRACT Objective: Cardiovascular diseases represent the main cause of death in chronic kidney disease (CKD). We aimed to evaluate the prevalence and association of the hypertriglyceridemia-waist phenotype (HWP) and visceral adiposity index (VAI) with cardiometabolic risk factors (CR) in patients with CKD on hemodialysis (HD). Materials and methods: The study is based on a cross-sectional design with 265 HD patients in two cities in northeastern Brazil. The VAI was calculated considering the variables body mass index (BMI), waist circumference (WC), triglycerides (TG) and high density lipoprotein cholesterol (HDL-c). HWP was defined as the concomitant elevation of WC and TG. The Poisson Regression Model with robust variance estimation was adjusted considering a hierarchical approach for explanatory variables. Prevalence ratios (PR) were also estimated. The level of significance adopted was 5%. Results: In our study HWP and VAI prevalence’s were 29.82% and 58.49%, respectively. In the final model, there was an association between VAI and female gender (PR = 1.46; p < 0.0001) and high body fat (% BF) (PR = 1.33; p < 0.0019). HWP was associated with females (PR = 1.80; p = 0.002), alcohol consumption (PR = 1.58; p = 0.033), obesity (PR = 1.89; p = 0.0001), high %BF (PR = 1.76; p = 0.012) and reduced HDL-c (PR = 1.48; p = 0.035). Conclusion: The HWP stood out as the association with more CR factors, representing a promising method for tracking cardiometabolic risk in HD patients, mainly female.

Resumo Introdução A síndrome metabólica (SM) é o agrupamento de fatores de risco associados à adiposidade central e à resistência à insulina. Objetivo O objetivo desta pesquisa foi analisar a prevalência da SM e os fatores associados em idosos de uma comunidade do município de Recife, Pernambuco. Método Estudo transversal com 166 idosos de ambos os sexos com idade igual ou superior a 60 anos, residentes na Comunidade dos Coelhos, no município de Recife. Para o diagnóstico da SM, foi utilizado o critério do NCEP-ATPIII. A análise dos dados foi efetuada com a utilização do programa estatístico SPSS para Windows, versão 13.1. Na comparação entre proporções, foram utilizados o teste de qui-quadrado de Pearson e o teste exato de Fischer. A razão de prevalência foi utilizada como medida de efeito considerando a SM como variável dependente. Resultados A prevalência de SM encontrada foi de 38,3%. Os fatores associados à SM após ajustes foram: a idade, na faixa etária 60-69 anos (44,4%, p = 0,047), o sexo feminino (43,1%, p = 0,056) e o excesso de peso (57,3%, p < 0,001). Conclusão A SM apresentou uma alta prevalência na população idosa avaliada, sendo associada às características demográficas e ao estado nutricional.

Abstract Background Metabolic syndrome (MS) is a clustering of risk factors associated with central adiposity and insulin resistance. Objective This study aimed to analyze the prevalence of MS and associated factors in older adults living in a subnormal urban cluster located in the city of Recife, state of Pernambuco, Brazil. Method A cross-sectional study was carried out with 166 older adults of both sexes aged ≥60 years residing in the Coelhos Community in Recife. MS was diagnosed through the NCEP/ATP III criteria. Data analysis was performed using the SPSS 13.1 statistical software. The Pearson's chi-squared test and the Fisher's exact test were used to compare the proportions. Prevalence ratio was used as an effect measure considering MS as dependent variable. Results Prevalence of MS was 38.3%. The factors associated with MS after adjustments were being 60-69 years old (44.4%, p=0.047), female (43.1%, p=0.056), and overweight (57.3%, p<0.001). Conclusion High prevalence of MS was observed in the older population evaluated, being associated with demographic characteristics and nutritional status. The group of older adults assessed should be provided with nutritional education and motivation to the practice of physical activities.

ABSTRACT Objective: evaluate the relationship between visceral/subcutaneous adipose tissue (VAT/SAT) and glomerular filtration rate (GFR). Methods: A case series study was conducted with 146 male and female adult outpatients at a hospital in Northeast Brazil. VAT and SAT were quantified using computed tomography and GFR was estimated using the formula proposed by the CKD Epidemiology Collaboration. The conceptual model also considered socio-demographic, clinical, anthropometric and lifestyle variables. Results: Females accounted for 71.9% of the sample and mean age was 52.5±13.2 years. Mean body mass index indicated obesity in both sexes (men:30.4±5.9 kg/m2; women: 31.6±6.1 kg/m2). For the same mean age and BMI, men had more VAT and a higher VAT/SAT ratio. Mean GFR was similar between sexes and within the normal range. Simple linear regression analysis revealed that 21.8% of the reduction in GFR in males could be explained by the VAT/SAT ratio (p=0.002). Among females, both VAT alone and the VAT/SAT ratio were predictors of GFR reduction (r2=4.8%, p=0.025 and r2=5.3%, p=0.019, respectively). Conclusion: Mean VAT and VAT/SAT ratio were compatible with abdominal obesity in both sexes and were related to a reduction in GFR.

RESUMEN Objetivo: Evaluar la relación entre el tejido adiposo visceral (TAV) y subcutáneo (TAS) con la tasa de filtración glomerular. Métodos: Estudio tipo serie de casos, en 146 pacientes adultos de ambos sexos, atendidos en un ambulatorio de un hospital de referencia en el Nordeste brasileño. El TAV y el TAS se cuantificaron por tomografía computadorizada y la tasa de filtración glomerular (TFG) estimada por la fórmula del grupo Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI). El modelo conceptual también consideró variables sociodemográficas, clínicas, antropométricas y de estilo de vida. Resultados: Pacientes con edad promedio de 52,5 ± 13,2 años y el 71,9% de sexo femenino. El promedio del IMC en ambos sexos se encuentra en el rango de obesidad (hombres= 30,4 ± 5,9 kg/m2 vs mujeres= 31,6 ± 6,1 kg/m2). Para un mismo promedio de edad e IMC, los hombres presentaron mayor TAV y mayor razón TAV/TAS que las mujeres. El promedio de la TFG fue similar entre los sexos y se encuentra en el rango normal. A través de regresión lineal simple, se evidenció que, en el sexo masculino, la disminución de la TFG puede explicarse en el 21,8% por la razón TAV/TAS (p=0,002). En el sexo femenino, tanto el TAV aislado como la razón TAV/TAS fueron predictores de disminución de la TFG (r2= 4,8%; p=0,025 e r2= 5,3%; p=0,019), respectivamente. Conclusión: Se evidenciaron valores muy elevados de los parámetros antropométricos de obesidad abdominal y promedio de TAV y de la razón TAV/TAS compatible con obesidad visceral en ambos sexos, siendo que estos dos últimos parámetros estuvieron relacionados al descenso de la TFG.

Abstract Objective: to verify the association of serum concentrations of 25-hydroxyvitamin D and glycemic levels with the genetic variants rs1544410 and rs2228570 of the VDR gene in adolescents from the Northeast region of Brazil. Materials and methods: a cross-sectional epidemiological study with 208 adolescents from public schools in the city of João Pessoa (Paraíba, Brazil) between 15 and 19 years of age. Blood samples were collected for DNA extraction and analysis of polymorphisms rs1544410 and rs2228570, as well as biochemical analyses (25-hydroxyvitamin D, parathyroid hormone, calcium and glycemia). Results: the mean age was 17.7 (± 1.14) years. Half of adolescents had sufficient serum levels of 25-hydroxyvitamin D and the other half had insufficient/deficient vitamin. The most frequent genotypic distribution was bb and Ff and of lesser frequency BB and ff. There was a significant relationship between the genotypes of rs1544410 and glycemia values (p = 0.049) in the relationships between the genotypes BBxbb (p = 0.012) and Bbxbb (p = 0.037); (p = 0.036, OR = 2.15, 95 % CI = 1.05-4.41), and in the BB+Bb group analysis when compared to the bb (p = 0.025, OR = 1.89, 95 % CI = 1.08-3.29) presented higher risk of glycemia above the median. On the other hand, when Bb+bb was analyzed in relation to BB, adolescents had a greater chance of blood glucose below the median (p = 0.025, OR = 0.66, CI = 0.47-0.95). Conclusion: this study showed a significant relation of glycemia with the distribution of rs1544410 polymorphism genotypes.

Resumen Objetivo: verificar la asociación de las concentraciones séricas de 25-hidroxivitamina D y los niveles de glucemia con las variantes genéticas rs1544410 y rs2228570 del gen VDR en adolescentes de la región noreste de Brasil. Materiales y métodos: se realizó un estudio epidemiológico transversal con 208 adolescentes de escuelas públicas en la ciudad de João Pessoa (Paraíba, Brasil) de entre 15 y 19 años de edad. Se recogieron muestras de sangre para la extracción de ADN y el análisis de los polimorfismos rs1544410 y rs2228570, así como para análisis bioquímicos (25-hidroxivitamina D, hormona paratiroidea, calcio y glucemia). Resultados: la edad media fue de 17,7 (± 1,14) años. La mitad de los adolescentes tenía niveles séricos suficientes de 25-hidroxivitamina D y la otra mitad, vitamina insuficiente/deficiente. La distribución genotípica más frecuente fue bb y Ff y la de menor frecuencia, BB y ff. Hubo una relación significativa entre los genotipos de rs1544410 y los valores de glucemia (p = 0,049) en las relaciones entre los genotipos BBxbb (p = 0,012) y Bbxbb (p = 0,037); (p = 0,036, OR = 2,15, IC 95 % = 1,05-4.41), y el análisis del grupo BB + Bb en comparación con el bb (p = 0,025, OR = 1,89, IC 95 % = 1,08-3,29) mostró un mayor el riesgo de glucemia, por encima de la mediana. Por otro lado, cuando se analizó Bb+bb en relación con la BB, los adolescentes tuvieron una mayor probabilidad de que la glucosa en sangre estuviera por debajo de la mediana (p = 0,025, OR = 0,66, IC = 0,47-0,95). Conclusión: este estudio mostró una relación significativa entre la glucemia y la distribución de genotipos de polimorfismo rs1544410.

RESUMO A Pesquisa Translacional é interdisciplinar e está apoiada em três pilares: pesquisa de bancada (básica), leito (aplicações clínicas) e comunidade (aplicações nos sistemas de saúde). O estudo, baseado nos cinco estágios da Pesquisa Translacional, resgatou o histórico da deficiência de vitamina A e da cegueira nutricional no Brasil (T0); o caminho da descoberta científica à escolha da intervenção – suplementação vitamínica (T1); a avaliação da eficácia da intervenção candidata por ensaio randomizado e controlado (T2); a avaliação da implementação e da cobertura na prática (T3); e a avaliação do impacto da intervenção (T4). Para verificar o impacto, aplicou-se a estatística superior de Wald, visando identificar quebras estruturais ao longo da série histórica da mortalidade geral de crianças entre 6 e 59 meses de idade. Para a região Nordeste, que apresentou a maior cobertura programática, o modelo sinalizou três quebras – agosto/1984, junho/1994 e maio/2006 –, nas quais foram estimadas reduções de 10%, 17% e 23%, respectivamente, na ocorrência mensal de óbitos infantis. O processo para a construção do conhecimento sobre a deficiência desta vitamina, a escolha da intervenção, a aplicação deste conhecimento no estabelecimento do Programa Nacional de Suplementação de Vitamina A e a avaliação do seu impacto configuram um exemplo de Pesquisa Translacional em saúde coletiva.

ABSTRACT Translational Research is interdisciplinary and supported by three pillars: bench (basic investigation), bedside (clinical applications) and community (applications in healthcare systems). The study, based on the five stages of translational research, reviewed the history of vitamin A deficiency and nutritional blindness in Brazil (T0); the pathway from scientific discovery to intervention choice – vitamin supplementation (T1); an assessment of the candidate intervention efficacy via randomized controlled trial (T2); the assessment of implementation and coverage in practice (T3) and the intervention impact assessment (T4). To estimate the impact, we applied Wald superior statistics to identify structural breaks along the time series of general mortality of children between 6 and 59 months of age. In the Northeast, region that presents the largest program coverage, the model pointed to three breaks: August/1984, June/1994 and May/2006, in which we estimated reductions of 10%, 17% and 23%, respectively, in the monthly incidence of children´s death. The process to construct knowledge about vitamin A deficiency, the choice of the intervention, the knowledge translation to establish the National Vitamin A Supplementation Program and the evaluation of its impact, constitute an example of translational research in collective health.
