Clinical Evolution of Preschool Picky Eater Children Receiving Oral Nutritional Supplementation during Six Months: A Prospective Controlled Clinical Trial.

OBJECTIVE: To determine if oral nutritional supplementation of picky eater children has a beneficial effect in addition to nutritional guidance on anthropometric parameters, nutrient intake, appetite, physical activity, and health complications. METHODS: This is a randomized, single-blind, controlled clinical trial that included Brazilian picky eater children aged 24 to 60 months. The individuals were randomized into a control group (CG) (n = 17) and an intervention group (IG) (n = 18), and were followed up in seven meetings for 180 days (baseline plus one meeting every 30 days). The CG received nutritional guidance for food selectivity, while the IG received the same guidance plus oral nutritional supplementation. Anthropometric and nutrient intake assessments were carried out, and appetite, physical activity and health complications were investigated. RESULTS: In the IG, the z-score of weight and height increased significantly over time (p < 0.05), while the body fat percentage (BFP) and BMI z-score remained unchanged. The percentage of inadequate intake of vitamins D, C and folate reduced in the IG over time compared to the CG (p < 0.05). In the IG, the score assigned by parents to the appetite scale increased over time (p < 0.05). There was no difference between the groups in the scores on the physical activity and global health scales, and in the number of health complications. CONCLUSIONS: Picky eater children that were supplemented increased their weight not by gaining fat, but due to an increase in stature, as shown by BMI z-score and BFP, that remained unchanged. Furthermore, they showed a decrease in inadequate micronutrient intake during the intervention. An improvement in appetite was also observed over time, attesting to the benefit of supplementation.

Anthropometric Indicators of Body Composition Associated With Lipid and Glycemic Profiles in Overweight Brazilian Children and Adolescents From 2008 to 2020.

Background: Anthropometric indicators have been used to predict health problems. The objective was to determine which indicators present better correlation with dyslipidemia, hyperglycemia and peripheral insulin resistance, as well as the cutoff points capable of predicting lipid and glycemic alterations in Brazilian children and adolescents. Methods: A cross-sectional study conducted with 568 overweight individuals, aged between 5 and 18 years, living in Southeast and South Brazilian regions, submitted to anthropometric and body composition evaluation by bioimpedance, in addition to fasting laboratory tests [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), fasting glycemia, and homeostasis model assessment-insulin resistance (HOMA-IR)]. Pearson's correlation was used to evaluate the association between anthropometric indicators and serum biomarkers. The ROC curve with Youden's J index was used to suggest anthropometric cutoff points with better ability to predict or rule out lipid and glycemic changes. Results: Cutoff points obtained for the z-score of body mass index (BMI), waist circumference (WC), and waist circumference for height (WC/H) showed high specificity (52 to 87%) and low sensitivity (23 to 59%), indicating greater ability to exclude changes in HDL-c, TG, and HOMA-IR levels. Cutoff points suggested for BMI ranged from +1.86 to +2.20 z-score. WC cutoff points ranged from +1.29 to +1.72, and, for the WC/H index, from +1.21 to +1.25. It was suggested the use of the following cutoff points to rule out changes in HDL-c, TG, and HOMA-IR values in clinical practice: BMI < z-score +2 and WC/H < z-score +1.29. In body fat percentage (BFP) analyses, the cutoff point < of 34% may be able to rule out changes in HDL-c (specificity of 70%), while the cutoff point > 36.6% may be able to predict changes in the HOMA-IR index (sensitivity of 76%). Conclusion: It is not yet possible to state which anthropometric parameter has the best correlation with lipid and glycemic alterations in overweight children and adolescents. We suggest considering BMI, WC, and WC/H cutoff points together to rule out changes in HDL-c, TG, and HOMA-IR, and use the BFP cutoff point to predict changes in HOMA-IR.

Anthropometric markers of abdominal adiposity and its relation to dyslipidemia and insulin resistance among overweight/obese schoolchildren and adolescents / Marcadores antropométricos de adiposidade abdominal e sua relação com dislipidemia e resistência à insulina em escolares e adolescentes com sobrepeso/obesidade

Objective: to assess the relationship between anthropometric indicators and laboratorial markers of cardiovascular risk in overweight/obese children and adolescents, in order to verify whether any anthropometric indicator has a better potential for use in screening cardiovascular risk in the population. Method: retrospective cross-sectional study enrolling 237 individuals aged 7 to 18 years. Body mass index (BMI), waist circumference (WC), waist circumference/height index (WC/H), glucose, HOMA-IR, total cholesterol (TC), LDL, HDL, triglycerides and TC/HDL and LDL/HDL indexes were obtained. Associations between anthropometric and laboratory markers were tested in contingency tables using the chi-square test. Correlations were tested by Spearman's correlation. Results: higher WC (Freedman cutoffs) was associated with lower levels of HDL and higher score in the TC/HDL and LDL/HDL indexes, but, using +2 z-scores as the cutoff, there were associations with low HDL and higher HOMA-IR. WC/H indicator (0.5 cutoff) was not associated with any of the outcomes, but, using +2 z-scores, an association was found with HOMA-IR. Z-scores of WC, WC/H and BMI showed positive correlation with HOMA-IR, TC/HDL and HOMA-IR, respectively. Negative correlations were found between WC and WC/H z-scores with HDL. WC and WC/H z-score were related to changes in HDL and HOMA-IR. Conclusions: there seems to be an advantage in using WC alone as a possible predictor of dyslipidemia and insulin resistance in children and adolescents. It is not possible to state that WC, WC/H or BMI measurements differ in their abilities to identify Brazilian children and adolescents with risk factors for cardiovascular diseases (AU)

Objetivo: avaliar a relação entre indicadores antropométricos e marcadores laboratoriais de risco cardiovascular em crianças e adolescentes com sobrepeso / obesidade, a fim de verificar se algum indicador antropométrico tem melhor potencial para uso no rastreamento de risco cardiovascular na população. Método: estudo transversal retrospectivo com 237 indivíduos com idades entre 7 e 18 anos. Índice de massa corporal (IMC), circunferência da cintura (CC), índice de circunferência da cintura / altura (CC / H), glicose, HOMA-IR, colesterol total (CT), LDL, HDL, triglicerídeos e índices CT/HDL e LDL/HDL foram obtidos. As associações entre marcadores antropométricos e laboratoriais foram testadas em tabelas de contingência por meio do teste do qui-quadrado. As correlações foram testadas pela correlação de Spearman. Resultados: CC mais elevado (pontos de corte de Freedman) foi associado a níveis mais baixos de HDL e maior pontuação nos índices TC/HDL e LDL/HDL, mas, usando +2 escores z como ponto de corte, houve associações com HDL baixo e HOMA-IR mais alto. O indicador CC/H (0,5 ponto de corte) não foi associado a nenhum dos desfechos, mas, usando +2 escores z, foi encontrada associação com o HOMA-IR. Os escores Z de CC, CC/E e IMC mostraram correlação positiva com HOMA-IR, TC/HDL e HOMA-IR, respectivamente. Correlações negativas foram encontradas entre CC e escores z de CC/H com HDL. CC e escore z de CC/H foram relacionados a mudanças em HDL e HOMA-IR. Conclusões: parece haver vantagem em usar a CC isoladamente como possível preditor de dislipidemia e resistência à insulina em crianças e adolescentes. Não é possível afirmar que as medidas de CC, CC/E ou IMC diferem na capacidade de identificar crianças e adolescentes brasileiros com fatores de risco para doenças cardiovasculares (AU)

Alcohol consumption and binge drinking among university students in a city in the state of Rondônia / Consumo de álcool e prática de binge drinkingentre universitários em uma cidade no interior de Rondônia

Objective: to verify the prevalence and pattern of alcohol consumption among the academics of a higher educa-tion institution located in the interior of the state of Rondônia. Methods: cross-sectional and observational study with all students enrolled in the institution in 2017. Were used the Alcohol, Smoking and Substance Involvement Screening Test to identify alcohol consumption and other classes of psychoactive substances. To characterize binge drinking was adopted the definition by the National Institute on Alcohol and Alcoholism and, and exclusion criteria was defined the questionnaire was not filled in completely and the request of the participant. The data were ana-lyzed with SPSS program 17. The univariate analysis was used to describe quantitative variables and the bivariate analysis to verify the association between the use of alcoholic beverages and the independent variables (sex, age) the level of significance was set at 5%. Results: 518 subjects participated in the study, with a mean age of 23.1 years, of which 355 (68.5%) were female and 163 (31.5%) were male. Among these, 385 (74.3%) stated that they consume alcoholic beverages, 282 (54.4%) started consuming less than 18 years and 239 (57%) reported practic-ing BD. Among BD practitioners, 48.9% do so at least once a month.Conclusion: there was a high prevalence of alcohol consumption and binge drinking among university students, which predisposes these individuals to physical, emotional, and social problems. Such findings should serve as a warning for the need for public policies aimed at preventing alcohol consumption that begins during adolescence (AU)

Objetivo: verificar a prevalência e o padrão de consumo de álcool entre acadêmicos de uma instituição de ensino superior do interior do estado de Rondônia.

Prevalence of childhood anaemia in Brazil: still a serious health problem: a systematic review and meta-analysis.

OBJECTIVE: To estimate the prevalence of anaemia in Brazilian children up to 83·9 months old. DESIGN: Systematic review and meta-analysis, using databases PubMed, Scopus, SciELO, Lilacs, Google Scholar, Periódicos Capes, Arca, Biblioteca Virtual em Saúde, Microsoft Academic Search and Cochrane Library using search terms: anaemia, prevalence, child and Brazil. PROSPERO Registration number: CRD42020208818. SETTING: Cross-sectional, cohort, case-control and intervention studies published between 2007 and 2020 were searched, excluding those who assessed children with an illness or chronic condition. The main outcome was anaemia prevalence. Random effects models based on the inverse variance method were used to estimate pooled prevalence measures. Sensitivity analyses removed studies with high contribution to overall heterogeneity. PARTICIPANTS: From 6790 first screened, 134 eligible studies were included, totalling 46 978 children aged zero to 83·9 months analysed, with adequate regions representativeness. RESULTS: Pooled prevalence of anaemia was 33 % (95 % CI 30, 35). Sensitivity analyses showed that withdrawal of studies that contributed to high heterogeneity did not influence national average prevalence. CONCLUSIONS: Childhood anaemia is still a serious public health problem in Brazil, exposing 33 % of Brazilian children to the anaemia repercussions. The main limitation of the study is the estimation of national prevalence based on local surveys, but a large number of studies were included, with representation in all regions of the country, giving strength to the results. In Brazil, more public policies are needed to promote supplementation, fortification and access to healthy eating to reduce the high level of anaemia among children.

La falacia de los niños gordos anémicos / The fallacy of the fat anemic child

Fundamento: los estudios sugieren la presencia de deficiencia de hierro en niños obesos, lo que conduciría a una mayor incidencia de anemia en este grupo. Objetivo: evaluar la prevalencia de anemia entre niños con sobrepeso y obesidad de dos niveles socioeconómicos y dos regiones diferentes en Brasil. Métodos: se obtuvieron datos de hemoglobina y antropometría de 598 niños y adolescentes con sobrepeso y obesidad de dos servicios especializados en la atención de estos niños. Resultados: la prevalencia global de anemia fue del 5,8% y el nivel medio de hemoglobina fue de 13,2 mg / dL, sin diferencia estadística para los dos indicadores según sobrepeso u obesidad y grupo de edad. Sin embargo, la hemoglobina media fue mayor entre los varones y, en el servicio con atención prestada a una población de menor nivel socioeconómico, la prevalencia de anemia fue mayor. Conclusión: la prevalencia de anemia encontrada en niños y adolescentes con sobrepeso y obesidad fue bastante baja, siendo mayor en la población más pobre. Para los niños y adolescentes con sobrepeso, la anemia parece estar más relacionada con el nivel socioeconómico que con la presencia de exceso de peso.

Background: studies suggest the presence of iron deficiency among obese children, which would lead to a higher incidence of anemia in this group. Aim: to assess the prevalence of anemia among overweight and obese children from two socioeconomic levels and two different regions in Brazil. Methods: hemoglobin and anthropometric data on 598 overweight and obese children and adolescents were obtained from two services specialized in the care of these children. Results: the overall prevalence of anemia was 5.8% and mean hemoglobin level was 13.2 mg/dL, with no statistical difference for the two indicators according to overweight or obesity and age group. However, the mean hemoglobin was higher among boys and, in the service with care provided to a population of lower socioeconomic status, the prevalence of anemia was higher. Conclusion: the prevalence of anemia found among overweight and obese children and adolescents was quite low, being higher in the poorest population. For overweight children and adolescents, anemia seems to be more related to socioeconomic status than to the presence of excess weight.

Vitamin E deficiency and associated factors among Brazilian school children / Deficiência de vitamina E e fatores associados entre crianças escolares brasileiras

ABSTRACT: Objective: Brazilian national data show a significant deficiency in pediatric vitamin E consumption, but there are very few studies evaluating laboratory-proven nutritional deficiency. The present study aimed to settle the prevalence of vitamin E deficiency (VED) and factors associated among school-aged children attended at a primary health unit in Ribeirão Preto (SP). Methods: A cross-sectional study that included 94 children between 6 and 11 years old. All sub-jects were submitted to vitamin E status analysis. To investigate the presence of factors associated with VED, socio-economic and anthropometric evaluation, determination of serum hemoglobin and zinc levels, and parasitological stool exam were performed. The associations were performed using Fisher's exact test. Results: VED (α-tocopherol concentrations <7 µmol/L) was observed in seven subjects (7.4%). None of them had zinc deficiency. Of the total of children, three (3.2%) were malnourished, 12 (12.7%) were anemic, and 11 (13.5%) presented some pathogenic intestinal parasite. These possible risk factors, in addition to maternal-work, maternal educational level, and monthly income, were not associated with VED. Conclusions: The prevalence of VED among school-aged children attended at a primary health unit was low. Zinc deficiency, malnutrition, anemia, pathogenic intestinal parasite, maternal-work, maternal educational level, and monthly income were not a risk factor for VED. (AU)

RESUMO: Objetivo: Determinar a prevalência da deficiência de vitamina E (DVE) e os fatores associados a essa deficiência em escolares atendidos em uma unidade básica de saúde de Ribeirão Preto (SP). Métodos: Estudo transversal que incluiu 94 crianças entre 6 e 11 anos de idade, atendidas em uma unidade básica de saúde. Todos os indivíduos foram submetidos à análise do status de vitamina E. Para investigar a presença de fatores associados à DVE, foi realizada avaliação socio-econômica e antropométrica, determinação dos níveis séricos de hemoglobina e zinco, e exame parasitológico de fezes. As associações foram realizadas por meio do teste exato de Fisher. Resultados: A DVE (concentrações de α-tocoferol <7 µmol/l) foi observada em sete indivíduos (7,4%). Nenhum sujeito apresentou deficiência sérica de zinco. Do total de crianças, três (3,2%) eram desnutridas, 12 (12,7%) anêmicas e 11 (13,5%) apresentavam algum parasita intestinal patogênico. Estes possíveis fatores de risco, além do trabalho materno, escolaridade materna e renda mensal, não foram associados à DVE (p>0,05). Conclusão: A prevalência de DVE em escolares atendidos em uma unidade básica de saúde foi baixa. Desnutrição, anemia, parasitose intestinal, renda mensal e trabalho e nível educacional maternos não se apre-sentaram como fatores de risco para a DVE. (AU)

Sedentary lifestyle among adolescents living in the city of Ribeirão Preto (SP) / Estilo de vida sedentário entre adolescentes na cidade de Ribeirão Preto (SP)

INTRODUCTION: Physical inactivity has been pointed out as one of the major public health problems of the 21st century and the benefits of the regular practice of physical activity during adolescence are important for the biological process of growth and development. OBJECTIVE: To analyze the prevalence of physical inactivity among adolescents enrolled in schools in the city of Ribeirão Preto (SP). METHODS: From September 1 to November 30, 2013, a cross-sectional, observational and descriptive study was conducted with adolescents enrolled in 14 state schools in the city of Ribeirão Preto (SP) using the International Physical Activity Questionnaire, short version. RESULTS: A total of 535 adolescents participated, 35% of them boys and 65% girls; 65% were 10 to 14 years old and 35% were 15 to 19 years old; 52.3% studied in the evening period and 10.3% worked part time on a daily basis. Regarding the level of physical activity, 15.5% of the boys and 24.1% of the girls were classified as sedentary (p>0.05). 60.4% of the boys performed physical activity of vigorous intensity, while 56.3% of the girls showed preference for physical activity of low or moderate intensity (p=0.03). The girls aged 15 to 19 years spent more time sitting during the week, while the girls aged 10 to 14 years were less active during the weekend. 24.2% of the girls aged 10 to 14 years who studied during the morning period and 13.7% of the boys and 18% of the girls who studied during the evening period were classified as sedentary. CONCLUSION: High rates of sedentary lifestyle were observed among adolescents enrolled in state (or public?) schools in Ribeirão Preto (Brazil). Girls presented higher rates of sedentary lifestyle than boys. Boys performed physical activity of vigorous intensity more frequently than girls. The older girls had higher rates of physical inactivity (hours spent in the sitting position) during the week days compared to the younger ones, while the latter spent more time in physical inactivity during the weekend.

INTRODUÇÃO: Adolescência é o período de transição entre a infância e a vida adulta, caracterizado por modificações no desenvolvimento físico, emocional, sexual e social e pelos esforços em alcançar os objetivos relacionados às expectativas culturais da sociedade em que vive, OBJETIVO: Avaliar a prevalência de inatividade física entre adolescentes matriculados em escolas da cidade de Ribeirão Preto (SP). MÉTODO: Estudo transversal, observacional e descritivo realizado entre 01/09/2013 e 30/11/2013, com adolescentes matriculados em 14 escolas estaduais da cidade de Ribeirão Preto (SP), utilizando-se o International Physical Activity Questionnarie, versão curta. RESULTADOS: Participaram 535 adolescentes sendo 35 % masculino e 65 % feminino; 65% tinham entre 10 e 14 anos e 35% entre 15 e 19 anos; 52,3% estudavam no período vespertino e 10,3% trabalhavam meio período ao dia. Quanto ao nível de atividade física encontrou-se 15,5% dos meninos e 24,1% das meninas classificados como sedentários (p>0,05). As moças com idades entre 10 e 14 anos referiram nível de atividade física menor que as da faixa etária dos 15 aos 19 anos (p= 0,507). 60,4% dos rapazes realizam atividade física de intensidade vigorosa enquanto 56,3% das moças mostraram preferência por atividades físicas de intensidade baixa ou moderada (p=0,03). As moças na faixa etária dos 15 aos 19 anos passam mais tempo sentadas durante a semana, enquanto que nos finais de semana são menos ativas aquelas com idades entre 10 e 14 anos. Classificou-se como sedentários 24,2% das moças com idades entre 10 e 14 anos que estudam no período da manhã e, no período vespertino, 13,7% dos rapazes e 18% das moças na faixa etária dos 15 aos 19 anos. CONCLUSÃO: A prevalência de sedentarismo foi de 21% sendo maior para o sexo feminino na faixa etária dos 10 aos 14 anos, que são menos ativas nos finais de semana e que estudam no período da manhã

Aleitamento materno e seus benefícios para a saúde da mulher / Breastfeeding and the benefits of lactation for women's health

A oferta do seio materno às crianças é um direito inquestionável das mães e de seus filhos, e todos os esforços devem ser feitos no sentido de promover, acompanhar e manter o aleitamento materno exclusivo até os 6 meses e complementado até que a criança complete 2 anos de idade. A literatura apresenta incontáveis publicações acerca das qualidades do leite materno, seus benefícios e repercussões para a saúde, estimulando a prática do aleitamento materno e embasando campanhas. Porém, mesmo sendo de conhecimento geral que a amamentação é uma importante etapa no processo reprodutivo da mulher e que sua prática oferece benefícios para mãe e filho, a grande maioria das informações destaca os benefícios que o leite materno oferece às crianças, esquecendo-se de mencionar todas as repercussões que o aleitamento materno traz para a saúde da mãe. Assim, o objetivo deste artigo é destacar os inúmeros benefícios que o aleitamento materno proporciona à saúde física e emocional da lactante. Para tanto, os autores consultaram artigos publicados nas bases de dados PubMed, Biblioteca Virtual de Saúde e Web of Science utilizando as palavras-chave aleitamento materno, leite materno, lactação e saúde materna.(AU)

The offer of the maternal breast to the baby is an unquestionable right of mothers and their children, and all efforts should be made to promote, follow and maintain exclusive breastfeeding for up to 6months and supplement it until the child completes 2 years of age. Many publications are available in the literature about the qualities of breast milk, its benefits and health repercussions, stimulating the practice of breastfeeding and supporting campaigns for its implementation. However, although it is widely known that breastfeeding is an important step in the reproductive process of women and its practice offers benefits to both mother and child, most of the available information highlights the benefits of breast milk for children, while mention of the effects of breastfeeding on the health of the mother is usually neglected. Thus, the objective of the present study is to highlight the multiple benefits of breastfeeding for the physical and emotional health of the nursing mother. The authors consulted articles published in the databases PubMed, Virtual Health Library and Web of Science using the keywords breastfeeding, breast milk, lactation and maternal health.(AU)

Uma experiência exitosa de meio século da Universidade de São Paulo junto à comunidade / A successful experience of half a century of the University of São Paulo with the community

A extensão constitui-se em parte indissociável das atividades universitárias e elo fundamental da interface da academia com a comunidade. A participação da universidade na assistência à saúde da comunidade talvez represente uma das faces mais visíveis e, ao mesmo tempo, sensíveis da extensão universitária. A atuação da Universidade de São Paulo (USP) no Centro Médico Social Comunitário "Vila Lobato" (CMSC "Vila Lobato") tem se constituído por uma experiência exitosa de meio século junto à comunidade servida por esta unidade básica de saúde de Ribeirão Preto. Alunos de graduação do curso de medicina e de nutrição e metabolismo da Faculdade de Medicina de Ribeirão Preto-USP (FMRP-USP) e, também, médicos residentes do Hospital das Clínicas da FMRP-USP têm prestado assistência à saúde à população local. Alunos de graduação de outras unidades do Campus de Ribeirão Preto da USP (odontologia, enfermagem e psicologia) também atuam no CMSC "Vila Lobato". Inúmeros projetos de pesquisa na área da saúde foram e continuam sendo desenvolvidos na unidade, beneficiando a comunidade. A experiência de meio século da USP junto ao CMSC "Vila Lobato" constitui-se por modelo bem-sucedido de extensão universitária, devendo não somente ser reconhecido de forma genuína no meio acadêmico, mas também estimulada. (AU)

The university extension program is inseparable from the university activities and also an essential connection between the academia and the community. The participation of the university in health care to the community may represent one of the most visible and at the same time sensitive aspects of university extension. The work of the University of São Paulo (USP) at the Community Social Medical Center "Vila Lobato" (CSMC "Vila Lobato") has been a successful experience of half a century in the community assisted by this primary health care unit of Ribeirão Preto. Undergraduate students of both Medicine and Nutrition and Metabolism courses from Ribeirão Preto Medical School-USP (RPMS-USP) and also resident physicians from the General Hospital of RPMS-USP have provided health care to the local population. Undergraduate students from other schools from USP at Ribeirão Preto (dentistry, nursing, and psychology) have also worked at the CSMC "Vila Lobato". Several research projects on health were carried out, and many others have been developed in the unit, benefiting the community. This experience of half a century of USP with the CSMC "Vila Lobato" is a successful model of university extension, and it should be recognized genuinely in the academic institutions and also stimulated.

Do all infants need vitamin D supplementation?

A high prevalence of vitamin D deficiency (VDD) in children has been observed worldwide, but there are few studies on the nutritional status of vitamin D (VD) in healthy infants. The main cause of deficiency in healthy children is breastfeeding without supplementation and lack or insufficiency of sun exposure. The aims of this study were to determine serum concentrations of 25(OH)D and verify its association with parathyroid hormone (PTH) concentrations and use of VD supplementation in healthy infants aged ≥ 6 to ≤ 24 months attended at two Primary Health Care Units in Ribeirão Preto city, São Paulo, Brazil. A cross-sectional, observational and analytical study was performed in which serum concentrations of 25(OH)D, PTH, alkaline phosphatase (AP), calcium (Ca), phosphorus (P) and albumin were determined in 155 healthy infants. Information on sun exposure, sociodemographic aspects of mothers and clinical and nutritional characteristics of infants were obtained through interviews with responsible infants's legal representatives. Ten infants (6%) presented deficient 25(OH)D serum concentration (≤20ng/ml) and 46 (30%), insufficient (21 to 29ng/ml). No changes in serum P, Ca and albumin concentrations were detected. Only one infant had an increase in PTH serum concentrations. 35% (55/155) of infants had high AP e 40% (22/55) presented insufficient serum concentrations of 25(OH)D but none presented deficient ones. There was a weak association between serum concentrations of 25(OH)D and PTH and an association between serum concentrations of 25(OH)D and P when adjusted for sex, age and BMI. There were no associations between inadequate serum concentrations of 25(OH)D (deficient ou insufficient), sun exposure and VD supplementation. This study found a low prevalence of deficient 25(OH)D serum concentration and high prevalence of insufficient ones which was not associated with changes in serum PTH, AP, P, Ca and albumin concentrations, VD supplementation and the formula volume intake.

Bioelectrical Impedance Vector Analysis in Healthy Term Infants in the First Three Months of Life in Brazil.

OBJECTIVE: Bioelectrical impedance vectorial analysis (BIVA) can be considered a favorable method for evaluation and monitoring of nutritional and hydration status without assumptions regarding body composition or requirement of prediction formulas. The present study aimed to determine bivariate tolerance intervals of the whole-body impedance vector for healthy term infants aged 1 to 3 months. METHODS: This is a descriptive cross-sectional study. Anthropometric and bioelectrical impedance data (800 mA-50 kHz) were obtained. Bivariate vector analysis was conducted with the resistance-reactance (RXc) graph method. BIVA software was used to construct the graphs. RESULTS: A total of 150 appropriate for gestational age infants (48.7% boys) who were exclusively breastfed and were 56.4 (SD = 23.1) days of age were studied. RXc tolerance ellipses (50, 75, and 95%) were constructed for boys and girls, but a general reference graph was defined for all infants considering the overlapping of ellipses between the genders. All graphs differed from those in national and foreign studies. CONCLUSION: New reference tolerance ellipses (95, 75, and 50%) for 1- to 3-month-old infants were constructed, pointing out the need for specific reference values of total body impedance vectors in different regions of Brazil. The RXc tolerance ellipses can be used for clinical practice and provide an easy method to evaluate and monitor body composition and hydration status.

O adolescente e a puericultura / Adolescent and puericulture

A partir do século XIX a adolescência passa a despertar grande interesse na sociedade em virtude do processo de desenvolvimento econômico, científico e social, o que impulsiona a criação de serviços de saúde direcionados ao atendimento dos indivíduos na segunda década de vida. Este artigo apresenta um breve histórico da Puericultura, da consolidação da Hebiatria e destaca a importância dos programas de atendimento em atenção básica à saúde do adolescente. Apoiado em alguns textos clássicos sobre o tema, procurou-se traçar um paralelo com os pioneiros programas de atendimento em puericultura para as crianças no sentido de incentivar as ações de prevenção de agravos e promoção da saúde dos adolescentes em nível primário, como estratégia para garantir boas condições de vida.

Comparação entre métodos de avaliação de altura final em adolescentes com baixa estura variante do normal / Comparison of methods for final height assessment in adolescents with a normal variant short stature

INTRODUCTION: Patients with low stature normal variant growth have peculiar evolutionary patterns making it difficult to precisely define when final stature will be reached, since prediction methods are based on parameters of difficult quantification, such as bone age. OBJECTIVE: To assess the agreement between two methods for prediction of final height based on family target range regarding the final height reached by adolescents with a diagnosis of normal variant short stature. METHODS: Thirty-three subjects were evaluated using height of parents for the calculation of family target range and Bayley-Pinneau and Tanner-Whitehouse methods for prediction of final height. Spearman correlation coefficient was calculated to correlate final height with the mean of the family target range, and the St. Laurent concordance coefficient was used to assess concordance between final stature and predictive methods. RESULTS: 87.9% (29/33) subjects kept short stature at the end of growth and 90.9% (30/33) had a final height within family target range. A very strong positive correlation (Cs = 0.77; p < 0.01) was observed between parental mean and final height. Bayley-Pinneau method showed a 0.47 concordance coefficient with final height (95% CI: 0.34; 0.57), and Tanner-Whitehouse 3 method showed a concordance coefficient of 0.58 (95% CI: 0.41; 0.75. CONCLUSION: The strong positive correlation observed demonstrates the significant influence of parental height on final height. Neither method showed good concordance when used as a predictor of final height, with height values being overestimated.

INTRODUÇÃO: Pacientes com baixa estatura variante normal do crescimento têm padrões evolutivos peculiares dificultando definir com precisão quando a estatura final será atingida, visto que os métodos de previsão baseiam-se em parâmetros de difícil quantificação, como a idade óssea. OBJETIVO: Avaliar a concordância entre dois métodos de previsão da estatura final e do canal familiar com a altura final atingida (padrão ouro) por adolescentes com diagnóstico de variantes normais da baixa estatura atendidos em ambulatório de avaliação de problemas de crescimento. MÉTODO: Foram avaliados 33 sujeitos utilizando-se as estaturas dos pais para o cálculo do canal familiar e da média parental e os métodos Bayley-Pinneau e Tanner- Whitehouse 3 para as previsões de estatura final. Também foram calculados o coeficiente de correlação de Spearman para correlacionar a estatura final com a média do canal familiar, e o coeficiente de concordância de St. Laurent para avaliar a concordância entre a estatura final e os métodos de previsão. RESULTADOS: 87,9% (29/33) permaneceram com Baixa Estatura ao término do crescimento e 90,9% (30/33) apresentaram estatura final dentro do canal familiar. Observou-se correlação positiva muito forte (Cs = 0,77; p < 0,01) entre a média parental e a altura final. O método de Bayley-Pinneau apresentou coeficiente de concordância com a altura final de 0,47 (IC 95%: 0,34; 0,57), o de TW3, 0,58 (IC 95%: 0,41; 0,75). CONCLUSÃO: A correlação positiva forte demonstra a influência significativa da altura dos pais na estatura final. Nenhum dos dois métodos apresentou boa concordância ao serem utilizados como preditores de estatura final, pois os valores das alturas foram superestimados principalmente pelo método de Bayley-Pinneau.

[Acute urinary retention in a pre-school girl with constipation]. / Retenção urinária aguda em pré-escolar feminina com constipação intestinal.

OBJECTIVE: To report a case of a preschool girl who developed acute urinary retention associated with constipation. CASE DESCRIPTION: A girl aged six years old presented a 24 hour history of inability to urinate. She was went twice to the emergency room during this period. In the first admission, 12 hours after the onset of the symptoms, she presented abdominal pain and acute urinary retention. After the drainage by urinary catheterization of 300 mL of clear urine, she presented relief of the symptoms and, as urinalysis had no change, the patient was discharged home. Twelve hours after the first visit, she returned to the emergency room complaining about the same symptoms. At physical examination, there was only a palpable and distended bladder up to the umbilicus with no other abnormalities. Again, a urinary catheterization was performed, which drained 450 mL of clear urine, with immediate relief of the symptoms. Urinalysis and urine culture had no abnormalities. During the anamnesis, the diagnosis of constipation was considered and a plain abdominal radiography was performed, which identified large amount of feces throughout the colon (fecal retention). An enema with a 12% glycerin solution was prescribed for three days. During follow-up, the child used laxatives and dietary modifications, this contributed to the resolution of the constipation. There were no other episodes of urinary retention after 6 months of follow-up. COMMENTS: Acute urinary retention in children is a rare phenomenon and constipation should be considered as a cause.

Nutritional status of adolescents with cystic fibrosis treated at a reference center in the southeast region of Brazil.

BACKGROUND: Several factors can interfere with the full physical and emotional growth of adolescents, among them chronic diseases. The aim was to determine the nutritional status of adolescents and to associate it with puberty, pancreatic sufficiency, lung function and age range of Cystic Fibrosis (CF) diagnosis. METHODS: An observational, cross-sectional, retrospective and analytical study was conducted using the data of medical records. SETTING: Reference center in the northeastern region of the state of São Paulo - Brazil. PATIENTS: All adolescents with CF attended in 2010 were included. Some variables included: pancreatic sufficiency (steatocrit >2 %), pancreatic enzymes replacement (yes/no), pubertal status-Tanner criteria (prepubertal: M1/G1, pubertal: M2/G2 to M4/G4, postpubertal: M5/G5), age at CF diagnosis (<2 and ≥2 years of age), Lung function, measured as a predicted forced expiratory volume in 1 s (FEV1). Main outcome measures Nutritional indicators: body mass index for age (BMI/A) and height for age (H/A) with z-score calculated with Anthro Plus software. Cut-off reference points: ≥ z-score -3 and < z-score -2 (thinness); z-score -2 and ≤ z-score-z +1 (normal weight); >z-score +1 (overweight or obesity), and z-score <-2 (low or very low H/A). The groups were compared by the Kruskal-Wallis test. Level of significance: p<0.05. RESULTS: Thirty adolescents. Median (min;max) age: 14.4 (10.1;19.8) years. BMI/A and H/A z-score, respectively: early diagnosis of CF (-0.8; -1.1) or late diagnosis of CF (-0.5;-0.8); with pancreatic insufficiency (-0.7; -0.8) or without pancreatic insufficiency (-0.8; -0.5) and prepubertal (-0.8; -0.7) pubertal (-0.2; -1.5) or postpubertal (-0.7; -0.5). No significant difference (p>0.05) was observed. Patients with and without pancreatic insufficiency, presented H/A borderline z-score (p=0.05). Association between H/A and FEV1 was borderline (p=0.05). CONCLUSIONS: Adolescents presented adequate nutritional status, although with slightly lower values than those of developed countries. FEV1 lower levels occurred more frequently in adolescents with low H/A.

Early manifestations of cystic fibrosis in a premature patient with complex meconium ileus at birth / Manifestações precoces da fibrose cística em paciente prematuro com íleo meconial complexo ao nascimento

OBJECTIVE: To report a case of a preterm infant with complex meconium ileus at birth and cystic fibrosis. CASE DESCRIPTION: A male infant was born by vaginal delivery at 33 weeks and 5 days of gestational age with respiratory distress and severe abdominal distension. The exploratory laparotomy in the first day of life identified meconium ileus and secondary peritonitis. Ileal resection and ileostomy were performed, followed by reconstruction of the bowel transit at 20 days of life. At 11 days of life, the first immunoreactive trypsinogen (IRT) was 154 ng/mL (reference value = 70), and oral pancreatic enzymes replacement therapy was started. After 23 days, the second IRT was 172ng/mL (reference value = 70). At 35 days of age he was discharged with referrals to primary care and to a special clinic for CF for the determination of sweat chloride. He was received in the outpatient clinic for neonatal screening for CF at 65 days of life presenting malnutrition and respiratory distress. The sweat chloride test was performed, with a positive result (126mEq/L). COMMENTS: This case illustrates the rapid evolution of CF in a premature patient with complex meconium ileus as the first clinical manifestation.
