Abstract
Although studies show that the intake of ultra-processed products (UPP) has a negative impact on health, diet quality and dietary vitamin D, its influence on serum concentrations of this vitamin remains unknown; therefore, it is essential to verify the association between the UPP consumption and vitamin D deficiency. This is a cross-sectional, household, population-based study, carried out with 229 individuals aged 20 years or older, residents of the city of Teresina, Piauí, Brazil. Socio-demographic, lifestyle, food consumption and anthropometric data were collected. Food consumption was obtained using a 24-h food recall, and foods were grouped according to the NOVA classification. Plasma concentrations of calcidiol-25 (OH) D3 were determined by HPLC. Crude and adjusted binary logistic regression was applied to estimate the association between UPP consumption and vitamin D deficiency. Most individuals aged 20-39 years were vitamin D deficient (52·1 %). UPP contributed 19·9 % to the energetic intake of the participant's diet. This contribution was higher for individuals with vitamin D deficiency (22·5 %, P = 0·04). In addition, a high intake of UPP was associated with twice the risk of vitamin D deficiency in comparison with low consumption of UPP (OR: 2·05; CI 1·06, 4·50; P: 0·04). Our results suggest that the consumption of UPP may have a negative impact on serum concentrations of vitamin D; more studies are needed.

Abstract
Introduction Introduction: recent studies have suggested the use of neck circumference as a parameter capable of identifying risks of cardiometabolic complications and the accumulation of truncal fat caused by both antiretroviral therapy and the lifestyle of people with the human immunodeficiency virus (HIV). Objective: to investigate the relationship between neck circumference and anthropometric indicators and to assess cardiometabolic risk and truncal obesity through proposed cut-off points. Methods: cross-sectional study including 233 people with HIV. Demographic, socioeconomic, lifestyle and clinical data were collected using a structured questionnaire. The anthropometric evaluation included: weight, height, body mass index (BMI) measurements; waist (WC), neck (NC), arm and arm muscle circumferences; triceps and subscapular skinfolds and their sum. ROC curves were constructed to determine the accuracy of NC in predicting cardiometabolic risk in people living with HIV. Results: the sample was 57.5 % male, with a mean age of 38.4 years (95 %CI: 37.2-39.7 years). NC showed a positive and significant correlation with all anthropometric variables analyzed (p < 0.05), and a higher correlation strength with WC and BMI. The NC cut-off point selected as a predictor of risk of cardiac metabolic complications and truncal obesity in women was ≥ 32.4 cm, considering both WC and BMI. For men, the NC cut-off points were different when considering WC (≥ 39.6 cm) and BMI (≥ 38.1 cm) as a reference. It is worth noting that NC performed well in ROC curve analysis for men, while in women it was a poor performance. Conclusion: NC proved to be a promising indicator in the assessment of nutrition and health of people living with HIV, especially in men.

Abstract
BACKGROUND Robust evidence have shown diet or dietary components in playing a direct role on cancer chemoprevention such as breast cancer (BC), and also prevention against cancer therapy side effects. In this context, vitamin E isoforms have been associated with tumor suppression pathways, mainly related to proliferation, invasion, metastasis, tumor metabolism and chemoresistance. OBJECTIVE Therefore, we performed a systematic review with meta-analysis to assess the effects of vitamin E consumption and/or supplementation on breast cancer risk, treatment, and outcomes. METHODS The studies were selected in the electronic databases PubMed, Science Direct, Scopus and Web of Science. RESULTS A total of 22 articles were selected, which nine manuscripts we perform the meta-analysis. The summary effect estimate did not indicate any significant association between consumption versus non-consumption of total vitamin E and breast cancer risk. After assessing the effects of vitamin E supplementation on breast cancer risk, only two had data for comparison and vitamin E supplementation presented no impact on breast cancer risk. However, the summary effect estimate from the included studies indicated that vitamin E consumption was inversely associated with breast cancer recurrence in the control group. There are no significant results regarding dietary or supplemental vitamin E intake and BC risk reduction. CONCLUSION Finally, regarding recurrence, survival, and mortality, the results indicated that vitamin E consumption was inversely associated with breast cancer recurrence, although no association was found for breast cancer mortality.

Abstract
Objetivo: avaliar o perfil nutricional e as características da alimentação servida aos adolescentes em cumprimento de medida socioeducativa. Método: pesquisa quantitativa, transversal e descritiva. Foram pesquisados adolescentes com idades entre 13 a 19 anos e 11 meses. Resultados: observou-se que 48,3% dos adolescentes estavam na faixa dos 16 a 17 anos e eram procedentes de Teresina, Piauí. A maioria foi classificada como eutrófica, de acordo com índice de massa corpórea (74,6%), circunferência do braço (83%) e estatura/idade (91,5%). A avaliação da qualidade da dieta mostrou que energia (107,5%) e lipídios (101,9%) estavam dentro do preconizado, mas a dieta estava inadequada em relação a todos os micronutrientes. A densidade energética (1,7 kcal/g) e o NDpCal% (8,11%) estavam adequados. Conclusão: a avaliação da dieta dos adolescentes em cumprimento de medida socioeducativa mostrou inadequações em relação aos micronutrientes. Assim, maiores cuidados devem ser tomados no planejamento da alimentação servida aos adolescentes.

Abstract
Background:
Cardiovascular diseases (CVDs) are a group of pathologies that involve heart and blood vessel disorders and are considered the main cause of death in the world. Epidemiological studies have shown the association between low vitamin D (VD) levels and CVD. This vitamin, in addition to acting on bone metabolism, plays a role in modulating the cardiovascular system.
Objective:
The present study assesses the effects of VD levels on CVD through a systematic literature review.
Method:
For this purpose, the PICO strategy was used to prepare the guiding question, and articles were searched in the PubMed, Scopus, Science Direct, and Web of Science databases by two authors independently. To guarantee the quality of the evidence of the articles included in the review, the Newcastle-Ottawa scale was used. The literature review followed the PRISMA recommendations.
Results:
In this review, 22,757 articles were identified, but only 10 were considered eligible, of which 70% are prospective cohorts and 30% are retrospective cohorts. The study showed that low 25(OH)D levels correlate with an increased risk of cardiovascular events and death from CVD, including in patients who had preexisting CVD. However, one article did not demonstrate this association.
Conclusion:
As a result, VD correlates with cardiovascular events and the risk of death.

Abstract
OBJECTIVE To describe the methodological aspects of the Piauí home healthcare survey (ISAD-PI) and assess the relation between sampling plan, precision, and design effects, assuming that population health surveys are relevant instruments for health monitoring. METHODS ISAD-PI was a population-based cross-sectional study that analyzed the living conditions and health status of the population residing in urban areas in the municipalities of Teresina and Picos, in Piauí. Sampling was carried out by conglomerates in two stages: Primary Sampling Units and households. To calculate the sample size, we considered the stratification of the population in both cities, according to the age of the individuals. We evaluated the “non-response” rate (NRR) and estimated the proportions according to sex and age, as well as the prevalence of social determinants of health in order to assess the compliance of the sampling plan. Analyses related to the precision according to the coefficient of proportion variation of the standard error (Cv-pˆ) and the design effect (deff). Cv-pˆ less than 20% and deff less than 1.5 were considered adequate. The total NRR of households was 38.2% in Teresina and 38.3% in Picos. We carried out twenty-four proportion estimates in relation to age and sex and 48 prevalence of social and health determinants estimates, totaling 72 estimates. Among them, 71 had Cv-pˆ less than 20% and 61 had deff less than or equal to 1.5. CONCLUSION Data generated from the ISAD-PI may contribute to the assessment of health and morbidity conditions in the population. Furthermore, methodological aspects employed in this research may serve as a basis for studies carried out in other cities in Brazil.

Abstract
INTRODUCTION Malnutrition and kala-azar (or visceral leishmaniasis) are significant public health problems in different parts of the world. Immunity and susceptibility to infectious and parasitic diseases are directly linked to the host's nutritional state, but little is known about the interaction between nutrition and kala-azar. This study aimed to evaluate nutritional status with kala-azar and correlate these findings with the clinical and laboratory manifestations of the disease, and zinc and retinol levels. METHODS This was a cross-sectional study of 139 patients with kala-azar. Nutritional status classification was performed according to international recommendations. Parametric or nonparametric tests were applied whenever indicated in a two-sided test with a 5% significance level. RESULTS Weight loss and malnutrition were more frequent in adults. Body mass index-for-age, fat area of the arm, and upper arm muscle area were significantly associated with probability of death. The presence of human immunodeficiency virus, hepatomegaly, and splenomegaly was correlated with nutritional assessment. Blood leukocyte and lymphocyte, serum creatine, and vitamin A levels were significantly higher in adult men. Vitamin A levels were highly associated with the level of hemoglobin and C-reactive protein (CRP) in multivariate analysis. All patients had reduced plasma zinc levels, but this finding had no association with the outcome variables. CONCLUSIONS Malnutrition was correlated with severe disease and was more prevalent in older people with kala-azar. Vitamin A deficiency was associated with hemoglobin and CRP. Zinc levels were reduced in patients with kala-azar.

Abstract
Breast cancer has a multifactorial etiology and, among the main causal factors, the dietary
profile stands out, mainly the components of the pro-inflammatory diet and their interaction with genetic
characteristics. In this sense, deciphering the molecular networks involved in the proliferation
of cancer cells in breast tissue can determine ways of action of organic compounds that modulate the
pathogenesis of cancer, such as vitamin A and analogs, as well as their possible mechanisms of modulation
of breast tumorigenesis. This is a review study conducted according to the guidelines of the
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and by consulting
the PubMed and Web of Science databases including articles, published in Portuguese, English and
Spanish, in the last five years. 126 articles were obtained, of which 13 were selected for full analysis
and only 6 were included in the study for meeting the eligibility criteria. The results of the compiled
studies demonstrate the role of some retinol-binding proteins in metabolism, as well as in differentiation,
cell proliferation and inflammation. Although controversial, the results point to the use of these
proteins as possible prognostic markers. The need for further studies in humans is also emphasized in
order to assess the main effects of vitamin isoforms on tumor activity.

Abstract
Background:
Regarding the multifactorial etiology of breast cancer, food choices, as well
as dietary intake, are the main modified factors in cancer prevention. In this sense, understanding
molecular pathways involved in breast cancer proliferation can help determine the mechanisms of
action of organic compounds such as antioxidant vitamins that are known to protect against cancer.
Objective:
Assess the mechanism of action of vitamin E in breast cancer modulation, with emphasis
on important markers of tumor development.
Methods:
It is a systematic review carried out in PubMed and Web of Science databases, from the
last 5 years, in Portuguese, English and Spanish. The following terms were selected according to The
Medical Subject Headings (MeSH): “breast cancer” OR “breast neoplasms”, “tocopherol” OR
“tocotrienols” OR “vitamin E”, as equated terms.
Results:
A total of 595 articles were found and 25 were selected according to inclusion criteria.
Vitamin E has been related to suppression/overexpression of important tumorigenic pathways,
mainly associated with proliferation, energy metabolism, chemosensitivity and invasion/metastasis.
Clinical studies of vitamin E supplementation are needed to assess the dose/response effect on breast
cancer patients.
Conclusion:
The safety of vitamin E supplementation is still controversial due to current studies design
available. However, when vitamin E is supplemented, the dose and therapeutic regimen must be
carefully decided, including the route of administration and breast cancer subtypes to enhance
desired effects and minimize unwanted side effects.

Abstract
Introduction: Food is closely linked with emotions in a complex relationship. The imaginary and symbolic meaning attributed to food has been little studied and the act of eating needs to be better understood. Objective: To analyze the association of adolescents´ feelings to selected foods. Methods: Cross-sectional study with 995 adolescents from public and private schools in Teresina, PI, Brazil. It was a Supplementary Project to the Brazilian national survey ERICA (Estudo de Riscos Cardiovasculares em Adolescentes). Adolescents had to choose one of the following feelings to selected food: well-being/satisfaction, malaise, no feeling, aversion. For the option aversion, the participant had to indicate if it was related to smell, color, appearance, or taste. Adolescents´ feelings to foods were analyzed by type of school, sex, and age range, using Pearson's chi-square (c²) or Fisher's exact tests. Results: There was significant differences regarding the type of school for the feeling to chocolate (p=0.015); vegetables (p=0.003); leafy greens (p=0.005); healthy sandwich/natural fruit juice (p≤0.001); high fat red meat (p=0.046); fruit/natural fruit juice (p≤0.001). For sex, there was significant difrerences for healthy sandwich/natural fruit juice (p=0.001); beans and rice (p=0.021) and high fat red meat (p=0.005). There was significant differences between age groups for sandwich, chips, soda and ice cream (p=0.018); pasta (p=0.047) and high fat red meat (p=0.021). Well-being predominated in almost all foods and aversion was poorly reported. Conclusion: The results suggest that adolescents' feelings are not directed to specific foods.

Abstract
SUMMARY OBJECTIVE To estimate the prevalence of hypertension in adults and analyze its association with socioeconomic, demographic, and lifestyle risk factors. METHODS Home-based cross-sectional epidemiological study conducted with adults of both sexes living in the cities of Teresina and Picos (PI). The prevalence of hypertension was estimated by self-reported diagnosis. The associations between hypertension and the following variables were tested: age, gender, skin color, education, family income, marital status, alcohol and cigarette consumption, physical activity, and nutritional status. RESULTS A total of 1,057 adult individuals with a mean age of 38.6 ± 11.5 years participated in the study, of which 62.3% were female. The prevalence of hypertension in the population was 16.4%. In the crude analysis, a significant association was observed between the prevalence of hypertension and factors such as older age, lower education, single marital status, brown skin color, smoking, and overweight (p < 0.05). However, after adjustments, only the associations with older age, brown skin color, sedentary lifestyle and overweight remained significant. CONCLUSION Older age, brown skin color, sedentary lifestyle, and the presence of overweight or obesity were significantly associated with hypertension. Among the modifiable risk factors, a sedentary lifestyle and overweight stand out as important for the genesis of hypertension, subject to intervention measures.

Abstract
The scope of this study was to determine the prevalence of anemia and the correlation between the concentration of hemoglobin and cognitive factors in an elderly population group resident in Campina Grande, Paraiba, Brazil. It was a cross-sectional study with individuals aged 60 or older. Men with hemoglobin levels <13 g / dL and women with levels <12 g / dL were considered anemic. Sociodemographic, cognitive condition and nutritional status variables were analyzed. Statistical analysis was performed by means of simple and multiple linear regression. Among the 360 elderly patients evaluated (67.2% women), the prevalence of anemia was 12.5%. The average concentration of hemoglobin found was 13.5 g / dL and was correlated to sex variables (β = -0.44, 95% CI: -1.35, -0.85), age (β = -0.14 ; 95% CI: -0.03, -0.01), nutritional status (β = 0.16; 95% CI: 0.01, 0.06), memory impairment (β = 0.12; 95% CI: - 0.06, -0.01), and dementia (β = -0.13, 95% CI: -0.06, -0.01). Routine blood testing among the elderly makes it possible to detect and treat anemia at an early stage. Actions geared towards the elderly who show a cognitive decline should be developed in the Basic Family Health Units in order to improve the quality of life of this population.

Abstract
O objetivo deste estudo foi avaliar a prevalência de desmame precoce e fatores associados em crianças atendidas na Estratégia Saúde da Família. Trata-se depesquisa quantitativa, descritiva e exploratória realizada com 241 crianças atendidas pela equipe de saúde. Para coleta dos dados foram usados um formulário e um questionário. Nas análises, para variáveis em que foram encontradas associações estatisticamente significativas foi realizado teste de regressão logística binária. A prevalência de desmame precoce foi de 58,51%. Maiores proporções de desmame precoce ocorreram em crianças com idade entre um e três meses. Pertencer a classe econômica B/C e ter recebido orientação sobre amamentação no pré-natal apresentaram-se significativamente associados com o desmame precoce. A prevalência do desmame precoce foi elevada, e considerada semelhante à prevalência nacional e descrita para o estado do Piauí. Houve associação entre o desmame precoce, classe econômica B/C e ter recebido orientação sobre amamentação no pré-natal.

Abstract
Globally, vitamin A deficiency (VAD) affects about 19.1 million pregnant women. Its occurrence is classically associated with inadequate food intake and may also be associated with socioeconomic factors and the presence of infection. The aim of this study was to determine the factors related to serum retinol levels among pregnant teenagers. The sample consisted of 89 pregnant adolescents, from whom socioeconomic, obstetric, anthropometric, and food consumption data were collected. Serum concentrations of retinol and the supposed presence of infection were determined by high-performance liquid chromatography and C-reactive protein quantification, respectively. The serum retinol concentrations were classified according to the criteria of the World Health Organization. We adopted a 5% significance level for all statistical tests. Serum retinol levels were significantly and positively associated with sanitation (p = 0.008) and pre-gestational nutritional status (p = 0.002), and negatively with the trimester (p = 0.001). The appropriate sanitation conditions and pre-pregnancy body mass index (BMI) were shown to have a protective effect against VAD. Conversely, serum retinol levels were reduced with trimester progression, favoring VAD occurrence.

Abstract
OBJECTIVE To evaluate the iron nutritional status of children from 6 to 59 months of age and its relation to vitamin A deficiency. METHOD Cross-sectional study involving 100 children, living in nine cities in the state of Paraíba, which were selected for convenience to form two study groups: children with vitamin A deficiency (serum retinol < 0.70 μmol/L; n = 50) and children without vitamin A deficiency (serum retinol ≥ 0.70 μmol/L; n = 50). The iron nutritional status was evaluated by biochemical, haematological and hematimetric indices. The cases of subclinical infection (C-Reactive Protein ≥ 6 mg/L) were excluded. RESULTS Children with vitamin A deficiency had serum iron values statistically lower than the corresponding values in children without deficiency. The other iron nutritional status indices showed no statistical difference according to presence/absence of vitamin A deficiency. CONCLUSION The interaction between iron and vitamin A deficiencies was evidenced in the case of circulating iron deficiency (serum iron), suggesting failure in the transport mechanisms of the mineral in children with vitamin A deficiency.

Abstract
El presente estudio buscó analizar la asociación entre la (in)seguridad alimentaria y el estado nutricional de niños preescolares asistidos en jardines infantiles. La seguridad alimentaria fue evaluada a través de la Escala Brasileña de Inseguridad Alimentaria (EBIA). El estado nutricional se evaluó a través del peso/edad, talla/edad, hemoglobina, retinol sérico y zinc sérico. Fueron encontradas prevalencias de déficit de estatura (6,2%), déficit de peso/edad (2,1%), deficiencia de vitamina A (24,4%), anemia (15,5%) y deficiencia de zinc (15,0%). La inseguridad alimentaria familiar fue caracterizada en 64,2% de las familias predominando la forma leve (32,6%). El estudio concluye que la inseguridad alimentaria estimada por la EBIA no se asoció a los Escore-z de crecimiento ni a las concentraciones de retinol sérico, hemoglobina y zinc sérico.

Abstract
OBJETIVO: Avaliar a relação entre os índices antropométricos e os níveis de retinol sérico em crianças menores de cinco anos do Estado da Paraíba. MÉTODOS: Estudo de corte transversal, de base populacional, envolvendo 1 205 crianças. O estado nutricional de vitamina A foi avaliado pelas concentrações séricas de retinol. O estado nutricional antropométrico foi avaliado utilizando-se os índices peso/altura e altura/idade. RESULTADOS: Crianças na faixa etária de 6 a 12 meses com deficit de altura apresentaram concentrações de retinol sérico significantemente inferiores quando comparadas às crianças sem deficit de altura (p=0,02). CONCLUSÃO: A associação observada entre deficit de altura e menores níveis de retinol sérico em crianças de menor faixa etária mostra a maior vulnerabilidade desse grupo para sofrer deficits vitamínicos e de crescimento.

Abstract
Background With subclinical infection, serum iron concentrations are reduced, altering the synthesis of hemoglobin, the main indicator of anemia. Objective To evaluate the association between subclinical infection and anemia in children of Paraíba State. Methods This is a cross-sectional study involving 1116 children aged 6 to 59 months from nine municipalities of Paraíba State. Demographic and socioeconomic data were collected by means of a specific questionnaire. The C-reactive protein and hemoglobin levels were determined by the latex agglutination technique and automated counter, respectively. C-reactive protein values ≥ 6 mg/L were used as indicative of subclinical infection, while the presence of anemia was determined by hemoglobin values < 11.0 g/dL. The data were analyzed using the Epi Info computer program, with significance being set at 5%. Results Data from this research showed that 80.1% of the children belonged to families that were below the bread line, with per capita income < ½ of the minimum wage at that time (R$ 350.00 approximately US$ 175.00). The prevalences of subclinical infection and anemia were 11.3% and 36.3%, respectively. Subclinical infection was significantly associated with anemia (p-value < 0.05). There were lower levels of hemoglobin in children with C-reactive protein ≥ 6 mg/L, with a mean hemoglobin level in children with subclinical infection of 10.93 g/dL (standard deviation - SD = 1.21 g/dL) and without infection of 11.26 g/dL (SD = 1.18 g/dL) (p-value < 0.05). Conclusion Anemia is associated with subclinical infection in this population, indicating that this is an important variable to be considered in studies of the prevalence of anemia in children.

Abstract
OBJETIVO: Analisar a prevalência da deficiência de vitamina A em crianças e os fatores associados. MÉTODOS: Estudo de corte transversal de base populacional realizado com 1.211 crianças de seis a 59 meses de idade, de ambos os sexos, procedentes da área urbana de nove cidades do estado da Paraíba, Brasil. O estado nutricional de vitamina A foi avaliado pelas concentrações séricas de retinol e presença de infecção subclínica avaliada pelas concentrações de proteína C-reativa. Foram investigadas as condições socioeconômicas, demográficas, de saneamento, além da suplementação prévia com vitamina A. Foram consideradas com deficiência de vitamina A as crianças com concentrações de retinol sérico < 0,70 µmol/L. Níveis séricos de vitamina A < 0,70 µmol/L com prevalência ≥ 20% foram considerados como grave problema de saúde pública. Análises uni e multivaridas foram conduzidas para testar associações estatísticas (p < 0,05). RESULTADOS: A prevalência de deficiência de vitamina A foi de 21,8% (IC95% 19,6;24,2), mostrando associação com a presença de infecção subclínica e ausência de água no domicílio. A prevalência de deficiência de vitamina A foi de 21,8% (IC95% 19,6;24,2). Após ajuste para confundimento, a deficiência de vitamina A mostrou-se associada com a presença de infecção subclínica e com a ausência de água no domicílio. A ocorrência da deficiência de vitamina A foi quatro vezes maior (IC95% 1,49;10,16) em crianças com infecção subclínica e sem água no domicilio, comparativamente às crianças sem infecção e com água no domicílio. CONCLUSÕES: Apesar das ações de prevenção e controle da deficiência de vitamina A, a hipovitaminose A ainda configura-se como um problema de saúde pública preocupante entre as crianças menores de cinco anos.

Abstract
OBJETIVO: Analisar a relação entre os níveis de hemoglobina, concentração de retinol sérico e estado nutricional em crianças de 6 a 59 meses de idade do estado da Paraíba. MÉTODOS: Corte transversal, de base populacional, envolvendo 1.108 crianças de 6 a 59 meses de idade, de ambos os sexos, do Estado da Paraíba. As concentrações de hemoglobina foram analisadas em sangue venoso por meio decontador automático, e as de retinol sérico por cromatografia líquida de alta resolução. Para a avaliação do estado nutricional energético-proteico, foram utilizados peso e estatura pelos índices: peso/idade, estatura/idade e peso/estatura em escores-Z. As proporções foram comparadas pelo teste do Qui-quadrado de Pearson e teste exato de Fisher, e a associação entre as concentrações de hemoglobina e de retinolemia e o estado nutricional, pelo modelo de regressão de Poisson. RESULTADOS: Observou-se prevalência de 36,5% (IC95%=33,7-39,3) de anemia (Hb<11,0 g/dL), 21,4% (IC95%=17,3-22,2) de hipovitaminose A (<0,70µmol/L), 7,3% (IC95%=5,8-8,8)) de desnutrição crônica (estatura/idade<-2), 1,3% (IC95%=0,6-2,0) de desnutrição global (peso/idade<-2), e 2,3% (IC95%=1,4-3,2) de desnutrição aguda (estatura/idade<-2). Na análise multivariada, observou-se associação direta entre anemia e retinolemia inadequada, assim como entre anemia e desnutrição crônica. CONCLUSÃO: A elevada prevalência da anemia e da hipovitaminose A impõe a adoção de medidas efetivas de prevenção e controle. A associação entre as carências nutricionais demonstrou que uma melhoria na retinolemia bem como no estado nutricional tende a reduzir a anemia no contexto estudado.

Abstract
OBJETIVO: Estimar a prevalência da anemia em crianças, sua tendência temporal e identificar fatores associados. MÉTODOS: Estudo de corte transversal, de base populacional, envolvendo 1.108 crianças, com idade entre seis e 59 meses, de ambos os sexos, do Estado da Paraíba, em 2007. A hemoglobina foi analisada em sangue venoso com contador automático. Foram considerados para anemia valores < 11,0 g/dL, forma leve 9-11g/dL, moderada 7-9 g/dL e grave < 7,0 g/dL. As condições socioeconômicas e demográficas das crianças foram obtidas por meio de questionário aos pais ou responsáveis. As proporções foram comparadas pelo teste do qui-quadrado de Pearson, e a associação entre as concentrações de hemoglobina e potenciais fatores de riscos foi testada pelo modelo de regressão de Poisson. A tendência temporal da anemia foi avaliada pelo incremento/redução na prevalência de anemia nos anos de 1982, 1992 e 2007. RESULTADOS: A prevalência de anemia foi de 36,5% (IC95% 33,7;39,3). Observa-se que 1,3% (IC95% 0,7;1,8) foi na forma grave, 11,1% (IC95% 9,4;13,5) na forma moderada e 87,6% (IC95% 79,1;91,2) na forma leve. Houve um incremento de 88,5% nos casos de anemia no período entre 1982 e1992 e uma estabilização na prevalência entre 1992 e 2007. A análise ajustada no modelo de Poisson mostrou maior suscetibilidade à anemia nas crianças de seis a 24 meses de idade, naquelas amamentadas por seis meses ou mais, que co-habitavam com mais de quatro pessoas no mesmo domicílio e moravam em casas com menos de cinco cômodos. CONCLUSÕES: A alta prevalência de anemia mostra que continua sendo um importante problema de saúde pública no Estado da Paraíba. Apesar da estabilização na prevalência entre 1992 e 2007, a anemia apresenta-se em elevado patamar, o que impõe medidas mais efetivas de prevenção e controle.

Abstract
Background & Aims: To investigate the effect of vitamin A supplementation on parameters of the immune system of vitamin A-deficient children. Methods: The study was carried out in four phases: 1) determination of serum retinol in 631 children from 36 to 83 months of age; 2) assessment of immunological markers [immunoglobulins and complement fractions, immunophenotyping of T and B lymphocytes, and natural killer (NK) cells], blood count, and serum ferritin of 52 vitamin A-deficient children (serum retinol < 0.70 µmol/L); 3) supplementation of the 52 deficient children with 200,000 IU of vitamin A; 4) determination of serum retinol and the immunological parameters 2 months after vitamin A supplementation. Results: Before vitamin A supplementation, 24.0 % of the children were anemic and 4.3 %had reduced ferritin concentrations. There was no significant difference between mean values of retinol according to the presence/absence of anemia. The mean values of the humoral and cellular immunological parameters did not show a statistically significant difference before and after supplementation with vitamin A. Children with concomitant hypovitaminosis A and anemia presented a significant increase in absolute CD4 and CD8 T-cell counts after vitamin A supplementation (p < 0.05). Conclusion: Vitamin A had an effect on the recruitment of T and B lymphocytes to the circulation of children with hypovitaminosis A and anemia.

Abstract
Os acidentes causados por animais peçonhentos ainda constituem problema de Saúde Pública no Brasil. Embora a produção e a distribuição dos soros no país encontrem-se estabilizadas, há problemas relacionados à notificação de acidentes deste tipo em várias regiões. Considerando esta realidade, foi realizado um estudo transversal entre janeiro e dezembro de 2005, utilizando documentação indireta sobre os acidentes ofídicos ocorridos em Campina Grande e 80 municípios adjacentes à região, com o objetivo de conhecer o perfil epidemiológico e clínico deste tipo de caso. Todos os pacientes atendidos tiveram diagnóstico médico de acidente por serpentes realizado pelo Centro de Atendimento Toxicológico de Campina Grande (Ceatox-CG). Os dados foram coletados através da ficha de notificação do Sinan (Sistema Nacional de Notificação de Agravo do Ministério da Saúde). Para análise dos dados, foi utilizada estatística descritiva e os dados foram tabulados no programa Microsoft Excel 2003. Dos 1.443 atendimentos no Centro, 737 foram causados por animais peçonhentos e, destes, 277 foram provocados por serpentes peçonhentas e não peçonhentas. Os acidentes predominaram no sexo masculino, na faixa etária de 10 a 29 anos, principalmente em agricultores na zona rural, entre maio e novembro de 2005. O gênero Bothrops foi responsável pelo maior número de casos (71,5%), e as extremidades superior e inferior do corpo foram os locais de maior predominância de ataques. Na extremidade inferior, foi atingido principalmente o pé. Em relação à gravidade, foram mais frequentes os acidentes classificados como leves causados pelo gênero Bothrops e apenas um paciente evoluiu para óbito. A média do tempo de atendimento, em horas, foi superior a 12 horas nos acidentes considerados graves, causados pelos gêneros Bothrops e Crotalus. Nossos resultados concordam com o perfil epidemiológico nacional dos acidentes ofídicos, atingindo com maior frequência o sexo masculino - trabalhadores rurais, na faixa etária produtiva de 10 a 49 anos - atingindo, sobretudo, os membros inferiores, e a maioria desses acidentes foi atribuída ao gênero Bothrops.

Abstract
OBJETIVO: Avaliar as concentrações séricas de retinol e beta-caroteno de pré-escolares em Teresina, Piauí, com caracterização do perfil antropométrico e do consumo alimentar. MATERIAL E MÉTODOS: Estudo transversal envolvendo 135 crianças em creche municipal, com avaliação do estado nutricional pelos métodos: bioquímico (concentração sérica de retinol e beta-caroteno), antropométrico (índices de peso para estatura - P/E e estatura para idade - E/I) e dietético (freqüência de consumo alimentar). RESULTADOS: Observou-se prevalência de deficiência de vitamina A (DVA) de 8,9% (IC95%: 4,7 - 15,0%) e existência de associação entre suplementação anterior e concentrações de retinol, com maior proporção de crianças com níveis normais de retinol entre as suplementadas (p = 0,025). As concentrações de retinol e de beta-caroteno mostraram-se correlacionadas, porém com força leve a moderada (p < 0,021). Os percentuais de crianças com baixo P/E e de baixa E/I foram de 1,9% (IC95%: 0,2 - 6,8%) e 9,7% (IC95%: 4,8 - 17,1%), respectivamente. Na avaliação dietética verificou-se baixo consumo de alimentos ricos em vitamina A. CONCLUSÕES: A elevada prevalência de DVA nas crianças, combinada com a alta percentagem de crianças com valores aceitáveis de retinol, os baixos valores medianos de beta-caroteno, a alta percentagem de déficit estatural e a inadequação do consumo de alimentos ricos em vitamina A, indicam a necessidade de se aprimorar as estratégias de educação em saúde e nutrição da população, incentivando o consumo de alimentos fontes de vitamina A, como medidas auto-sustentáveis importantes no combate ao problema. Além disso, deve ser considerado o incentivo à fortificação dos alimentos e ao fortalecimento de Programas de suplementação.

Abstract
OBJETIVOS: Avaliar a associação entre obesidade e dislipidemias em adolescentes do ensino público e privado de Campina Grande-PB, Brasil. MÉTODOS: Estudo transversal com 180 adolescentes de 14 a 17 anos matriculados no ensino público e privado de Campina Grande-PB. O estado nutricional foi classificado segundo os percentis do Índice de Massa Corporal para sexo e idade. Foi realizada coleta sangüínea para avaliação do perfil lipídico (colesterol total, frações HDL-colesterol, LDL-colesterol e triglicerídeos). Considerou-se dislipidemia a existência de alteração em pelo menos um dos exames. As análises estatísticas foram realizadas a partir do Epi Info 3.3 e Stata 7.0. RESULTADOS: A prevalência de sobrepeso foi de 14,4% enquanto que 83,9% dos estudantes eram eutróficos e 1,7% apresentavam baixo peso. Não foram encontradas diferenças estatisticamente significantes para o estado nutricional quando estratificado por sexo e tipo de escola. Todas as taxas bioquímicas investigadas mostraram algum nível de alteração. Chamou à atenção a prevalência de dislipidemia, observada em 66,7% dos estudantes, e a alteração do HDL-colesterol, verificada em 56,7% destes. Registrou-se associação estatisticamente significante (p<0,05) do Índice de Massa Corporal, categorizado em tercis, com o colesterol total e sua fração LDL, inclusive quando estratificados por sexo e tipo de escola. CONCLUSÕES: Considerando-se a faixa etária estudada, foram elevados os achados de sobrepeso e dislipidemia. Recomenda-se a adição de medidas preventivas, a fim de evitar que cada vez mais crianças e adolescentes venham a se tornar adultos portadores de obesidades e outras doenças crônicas.

Abstract
Vitamin A deficiency is a public health problem in the Northeast of Brazil. This study aimed to determine the prevalence of vitamin A deficiency and associated factors among preschool children in Teresina, Piauí, Brazil. We studied the serum retinol levels and socioeconomic and demographic characteristics of 631 children from 36 to 83 months of age. The statistical association between each of the above characteristics and serum retinol levels was investigated by univariate and multivariate linear regression analysis. Mean serum retinol was 1.21 mmol/L (95%CI: 1.17-1.25 micromol/L) and was independent of gender (p = 0.259). Prevalence of vitamin A deficiency (retinol < 0.69 micromol/L) was 15.4% (95%CI: 12.7-18.4), with a tendency to decrease with age. Acceptable but not adequate retinol levels (0.70 to 1.04 micromol/L) were observed in 29% of children (95%CI: 25.2-32.4). There were positive associations between retinol levels and age, income, vitamin A supplementation, and maternal schooling. Vitamin A deficiency appeared as a moderately serious public health problem, emphasizing the importance of strategies to combat this problem in the region.

Abstract
BACKGROUND Soluble transferrin receptor (sTfR) concentration is high in iron deficiency and in conditions of increased erythropoiesis. In developing countries like Brazil, pregnant women usually have concurrent iron, vitamin B(12), and folate deficiencies. This study investigated the relationship between serum sTfR concentration and iron, vitamin B(12), and folate status in pregnant women. METHODS The concentration of the sTfR, hematocrit (Hct), hemoglobin (Hb), red blood cell (RBC) and white blood cell (WBC) counts, serum iron (SI), total iron-binding capacity (TIBC), transferrin saturation, serum ferritin, zinc protoporphyrin (ZPP), vitamin B(12), and serum and RBC folate were determined in 40 healthy pregnant women who delivered term babies. RESULTS sTfR concentration was significantly higher when the women had iron deficiency (serum ferritin <10 microg/l, p<0.01), but there was no significant difference in sTfR concentration according to vitamin B(12), serum, and RBC folate concentrations. Women who had serum ferritin <10 microg/l also had lower vitamin B(12) values (p<0.01). There was no significant correlation between vitamin B(12) and serum folate with sTfR concentration. According to a regression analysis, sTfR concentration was associated with serum iron, serum ferritin, RBC count, and hemoglobin concentration. CONCLUSION Iron was the only micronutrient that influenced the sTfR concentration. Vitamin B(12) and folate concentrations were probably not sufficiently low to have an impact on the sTfR concentration.
