Disease activity index is associated with subclinical atherosclerosis in childhood-onset systemic lupus erythematosus.

BACKGROUND: Systemic lupus erythematosus (SLE) is an independent risk factor for cardiovascular events. The present study determined the prevalence of subclinical atherosclerosis in childhood-onset SLE using the carotid intima-media thickness (CIMT) measurement and investigated associations between traditional and nontraditional risk factors for atherosclerosis, such as medications, SLE Disease Activity Index - SLEDAI-2 K and SLICC-ACR damage index and CIMT. METHODS: Cross-sectional prospective study between 2017 and 2018. CIMT was assessed by ultrasonography. Data were collected by chart review, nutritional evaluation and laboratory tests and analyzed by Fisher, Wilcoxon-Mann-Whitney tests, multiple linear and log binomial regression. RESULTS: Twenty-eight patients (mean age 13.9 years, SD 3) were enrolled. The prevalence of subclinical atherosclerosis was 32% (95% CI 14.8, 49.4). The mean CIMT was 0.43 ± 0.035 mm. The most common traditional risk factors observed were dyslipidemia (82.1%), uncontrolled hypertension (14.2%), obesity (14.3%), and poor diet (78.6%). Uncontrolled hypertension (p = 0.04), proteinuria (p = 0.02), estimated glomerular filtration rate < 75 ml /min/1.73 m2 (p = 0.02) and SLEDAI-2 K > 5 (P = 0.04) were associated with subclinical atherosclerosis. SLEDAI-2 K > 5 maintained association with CIMT after adjusting for control variables. CONCLUSION: Subclinical atherosclerosis is frequently observed in cSLE, mainly in patients with moderate to severe disease activity.

Impact of multi-micronutrient supplementation on lipidemia of children and adolescents.

BACKGROUND: Micronutrient supplementation has been extensively explored as a strategy to improve health and reduce risk of chronic diseases. Fat-soluble vitamins like A and E with their antioxidant properties and mechanistic interactions with lipoproteins, have potentially a key impact on lipid metabolism and lipidemia. OBJECTIVE: The impact of micronutrients on lipid metabolism requires further investigation including characterization of plasma lipidome following supplementation and any cause-effect on circulating lipids. DESIGN: In this study, we elucidate the effect and associations of a multi-micronutrient intervention in Brazilian children and teens with lipoprotein alterations and lipid metabolism. RESULTS: Our analysis suggests a combination of short and long-term impact of supplementation on lipid metabolism, potentially mediated primarily by α-tocopherol (vitamin E) and retinol (vitamin A). Among the lipid classes, levels of phospholipids, lysophospholipids, and cholesterol esters were impacted the most along with differential incorporation of stearic, palmitic, oleic and arachidonic acids. Integrated analysis with proteomic data suggested potential links to supplementation-mediated alterations in protein levels of phospholipases and pyruvate dehydrogenase kinase 1 (PDK1). CONCLUSIONS: Associations between the observed differences in lipidemia, total triglyceride, and VLDL-cholesterol levels suggest that micronutrients may play a role in reducing these risk factors for cardiovascular disease in children. This would require further investigation.

Vitamin B2 and Folate Concentrations are Associated with ARA, EPA and DHA Fatty Acids in Red Blood Cells of Brazilian Children and Adolescents.

Vitamins B2, B6, B12, and folate are essential for methylation reactions and possibly influence the transport of polyunsaturated fatty acids in plasma and red blood cells (RBC). Associations between B-vitamin biomarkers and fatty acid (FA) profile were analyzed in Brazilian children and adolescents. This cross-sectional study included 249 children and adolescents, aged 9-13 years old. Dietary intake was assessed by the food frequency questionnaire and the healthy eating index (HEI). Biomarkers for vitamins B2, B6, B12, and folate were measured in plasma. The FA profile and the metabolites of one-carbon metabolism were measured in RBC. Associations were tested with multiple linear regression models. An increase of 1 nmol/L in vitamin B2 was associated with an increase of 0.19 mg/dL of EPA, 0.20 mg/dL of ARA, and 0.25 mg/dL of DHA in RBC. An increase of 1 ng/mL in plasma folate was associated with an increase of 0.14 mg/dL of EPA, 0.22 mg/dL of ARA, and 0.21 mg/dL of DHA in RBC. These findings highlight the importance of an adequate intake of vitamin B2 and folate in childhood, since they may improve the FA profile in RBCs and may help prevent cardiovascular disease.

Validation of the Brazilian Healthy Eating Index-Revised Using Biomarkers in Children and Adolescents.

The Brazilian Healthy Eating Index-Revised (BHEI-R) can be used to determine overall dietary patterns. We assessed the BHEI-R scores in children and adolescents, aged from 9 to 13 years old, and associated its component scores with biomarkers of health and dietary exposure. Three 24-h recalls were used to generate BHEI-R. Biomarkers were analyzed in plasma and red blood cells. Correlation tests, agreement, and covariance analyses were used to associate BHEI-R components with biomarkers. Data from 167 subjects were used. The strongest correlations were between fruits, vegetables and legumes with omega-6 and omega-3 fatty acids, and ß-carotene intakes. Milk and dairy correlated with plasma retinol and pyridoxine. All components rich in vegetable and animal protein sources correlated with plasma creatine. Total BHEI-R scores were positively associated with intakes of omega-6, omega-3, fiber and vitamin C, and inversely associated with energy and saturated fat intakes of individuals. Plasma ß-carotene and riboflavin biomarkers were positively associated with total BHEI-R. An inadequate food consumption pattern was captured by both biomarkers of health and dietary exposure. BHEI-R was validated for the above dietary components and can be associated with metabolomics and nutritional epidemiological data in future pediatric studies.

Bioelectrical Impedance of Vectorial Analysis and Phase Angle in Adolescents.

OBJECTIVES: Bioelectrical impedance can be interpreted by vector analysis using direct measures of the impedance vector; thus, collecting information about resistance (R), reactance (Xc), and phase angle (PA) makes it possible to classify an individual's nutritional status. The aim of this study was to investigate these values and construct bioelectrical references for healthy Brazilian adolescents. METHODS: This is a cross-sectional study that included 567 healthy adolescents, aged 10 to 18 years. The bioelectrical impedance was performed to collect data for R and Xc. In addition, weight and height were also collected. The PA was calculated, and thereby the tolerance and confidence ellipses were constructed using specific software. RESULTS: For boys the mean vectors of 11 and 12 years, 12 and 13 years, 13 and 14 years, and 15 and 16 years were different from each other (p < 0.05). For girls the only mean vectors with significant differences were 11 and 12 years (p = 0.0071). The results differ from those in the literature, possibly due to ethnic differences in body composition. CONCLUSION: The present study provides an important tool for monitoring the nutritional status of adolescents of different ages, without previous knowledge of some anthropometric measures such as body weight.

Low vitamin D status among pregnant Latin American and Caribbean women with HIV Infection.

OBJECTIVE: To evaluate the prevalence and predictors of low vitamin D status among pregnant women with HIV infection. METHODS: The present cross-sectional study analyzed repository specimens collected at 12-34 weeks of pregnancy among women enrolled across 17 sites in Latin America and the Caribbean between 2002 and 2009. Logistic regression modeling was used to identify factors associated with low vitamin D status (25-hydroxyvitamin D <30 ng/mL). RESULTS: Among 715 women, 218 (30.5%) were vitamin D deficient (<20 ng/mL) and 252 (35.2%) were insufficient (21- /mL). Factors associated with low vitamin D status included residence in subtropical latitudes (adjusted odds ratio [aOR] 1.97, 95% confidence interval [CI] 1.35-2.88), assessment during non-summer seasons (autumn: aOR 1.85, 95% CI 1.20-2.86; spring: 4.3, 2.65-6.95; winter: 10.82, 5.74-20.41), employment (aOR 1.56, 95% CI 1.06-2.38), and assessment before 20 weeks of pregnancy (aOR 1.89, 95% CI 1.18-3.06). Factors protective against low vitamin D status were CD4 count below 200 cells per mm(3) (aOR 0.45, 95% CI 0.26-0.77) and protease inhibitors (aOR 0.62, 95% CI 0.40-0.95). CONCLUSION: Low vitamin D status was prevalent among pregnant women with HIV infection. Further studies are warranted to identify the impact of low maternal vitamin D status.

Plasma homocysteine levels in HIV-infected men with and without lipodystrophy.

OBJECTIVE: Lipodystrophy syndrome is an unexpected clinical manifestation in patients infected with HIV and might be a clinical marker of increased risk for cardiovascular diseases (CVDs). Because hyperhomocysteinemia has been associated with CVD, the goal of the present study was to investigate homocysteine (Hcy) levels and their association with the factors of lipodystrophy syndrome in men with HIV. METHODS: Hcy metabolism-related molecules were determined in 13 men infected with HIV with lipodystrophy (HIV+LIP), 10 men with HIV without lipodystrophy (HIV), and 10 healthy controls (C). RESULTS: Significant (P < 0.05) increased Hcy plasma levels were found in HIV (20.5%) and in HIV+LIP (35.2%) compared with the control group. Plasma levels of vitamin B12 (HIV, 26.5%; HIV+LIP, 28.8%) and folate (HIV, 39.1% and HIV+LIP, 49.4%) were significantly (P < 0.05) lower in the two groups of HIV patients compared with control. HIV+LIP men presented raised plasma total sulfur-containing amino acids (20.1%) and lower total plasma thiol (11.3%) than controls. The same was not observed in the HIV group. Spearman's correlation test revealed significant (P < 0.05) association between plasma Hcy and duration of highly active antiretroviral therapy (HAART) and plasma insulin, as well as plasma adiponectin levels. CONCLUSION: Our results demonstrated that HIV+LIP men were more susceptible to disturbances in Hcy metabolism compared with men infected with HIV without lipodystrophy characteristics. Duration of HAART treatment, elevated plasma insulin, and low levels of adiponectin seem to be relevant for the appearance of these Hcy metabolic disorders.

Hypermetabolism and altered substrate oxidation in HIV-infected patients with lipodystrophy.

OBJECTIVE: Human immunodeficiency virus type 1 (HIV)-associated lipodystrophy syndrome compromises body composition and produces metabolic alterations, such as dyslipidemia and insulin resistance. This study aims to determine whether energy expenditure and substrate oxidation are altered due to human HIV-associated lipodystrophy syndrome. METHODS: We compared energy expenditure and substrate oxidation in 10 HIV-infected men with lipodystrophy syndrome (HIV+LIPO+), 22 HIV-infected men without lipodystrophy syndrome (HIV+LIPO-), and 12 healthy controls. Energy expenditure and substrate oxidation were assessed by indirect calorimetry, and body composition was assessed by dual-energy X-ray absorptiometry. The substrate oxidation assessments were performed during fasting and 30 min after eucaloric breakfast consumption (300 kcal). RESULTS: The resting energy expenditure adjusted for lean body mass was significantly higher in the HIV+LIPO+ group than in the healthy controls (P = 0.02). HIV-infected patients had increased carbohydrate oxidation and lower lipid oxidation when compared to the control group (P < 0.05) during fasting conditions. After the consumption of a eucaloric breakfast, there was a significant increase in carbohydrate oxidation only in the HIV+LIPO- and control groups (P < 0.05), but there was no increase in the HIV+LIPO+ group. CONCLUSION: Hypermetabolism and alteration in substrate oxidation were observed in the HIV+LIPO+ group.

Catch-up growth in children after repair of Tetralogy of Fallot.

PURPOSE: To evaluate the growth of children after repair of Tetralogy of Fallot, as well as the influence of residual lesions and socio-economic status. METHODS: A total of 17 children, including 10 boys with a median age of 16 months at surgery, were enrolled in a retrospective cohort, in a tertiary care university hospital. Anthropometric (as z-scores), clinical, nutritional, and social data were collected. RESULTS: Weight-for-age and weight-for-height z-scores decreased pre-operatively and recovered post-operatively in almost all patients, most markedly weight for age. Weight-for-height z-scores improved, but were still lower than birth values in the long term. Long-term height-for-age z-scores were higher than those at birth, surgery, and 3 months post-operatively. Most patients showed catch-up growth for height for age (70%), weight for age (82%), and weight for height (70%). Post-operative residual lesions (76%) influenced weight-for-age z-scores. Despite the fact that most patients (70%) were from low-income families, energy intake was above the estimated requirement for age and gender in all but one patient. There was no influence of socio-economic status on pre- and post-operative growth. Bone age was delayed and long-term-predicted height was within mid-parental height limits in 16 children (93%). CONCLUSION: Children submitted to Tetralogy of Fallot repair had pre-operative acute growth restriction and showed post-operative catch-up growth for weight and height. Acute growth restriction could still be present in the long term.

Lipid levels in the second year of life among HIV-infected and HIV-exposed uninfected Latin American children.

BACKGROUND: Dyslipidemia is observed among older children and adults with HIV. We examined nonfasting cholesterol and triglycerides in two groups of 12-23-month-old Latin American children - HIV-infected vs. HIV-exposed but uninfected (HEU). METHODS: HIV-infected and HEU children in Latin America and Jamaica were enrolled in an observational cohort. Eligibility for this analysis required having cholesterol and triglyceride results available during the second year of life. RESULTS: HIV-infected (n = 83) children were slightly older at the time of lipid testing than the HEU (n = 681). Forty percent of the HIV-infected children were on protease inhibitor-based antiretroviral therapy (ART); 41% were not on ART. There was no statistically significant difference in mean cholesterol concentrations (mg/dl) by HIV status; however, the HIV-infected children had higher mean triglyceride concentrations. The prevalence of high cholesterol (>200  mg/dl) and high triglycerides (>110 mg/dl) was higher among the HIV-infected vs. HEU. Among the HIV-infected children, mean cholesterol and triglyceride concentrations varied by ART. Children receiving no ART had a significantly lower mean cholesterol concentration. Those receiving protease inhibitor-containing ART had a significantly higher mean triglyceride concentration compared to the other two antiretroviral regimen groups. CONCLUSION: A greater proportion of HIV-infected children at 12-23 months have hyperlipidemia when compared to HEU children, with the highest triglyceride concentrations observed among those receiving protease inhibitor-containing ART, and the lowest cholesterol levels among those not receiving ART. Implications of these findings will require continued follow-up of HIV-infected children who initiate therapy early in life.

Clinical and metabolic profile of HIV-positive patients with lipodistrophy / Perfil clínico e metabólico de pacientes soropositivos para HIV portadores de lipodistrofia

Objective: To evaluate the clinical and metabolic profile of HIV-seropositive patients on HAART with a diagnosis of associated lipodystrophy. Methods: We analyzed data computed in a protocol attached to the records of patients treated at the University Hospital of the Medical School of Ribeirão Preto. Results: 69.7% of the participants were male. Mean ± standard deviation body mass index was 24.7 ± 3.6 kg/m2and 26.7 ± 5.98 kg/m2, and average weight 72.78 ± 12.7 kg and 65.94 ± 15.4 kg for males and females, respectively. The percentage of lean mass was greater in men (p = 0.0008) and body fat was greater in women (p = 0.0006)...

Objetivo: Avaliar o perfil clínico e metabólico dos pacientes soropositivo para HIV, em uso de terapia antiretroviral fortemente ativa (Highly Active Antiretroviral Therapy - HAART) e com diagnóstico de lipodistrofia associada. Métodos: A pesquisa foi realizada a partir da análise de dados computados em um protocolo anexado ao prontuário de pacientes atendidos na Unidade Especial de Tratamento para Doenças Infecciosas (UETDI), no Ambulatório de Dislipidemia (ADIS) do Hospital das Clínicas da Faculdade deMedicina de Ribeirão Preto (HC-FMRP). Resultados: 69,7% dos participantes eram do sexo masculino. As médias (DP) de IMC foram 24,7 ± 3.6 Kg/m2 e 26,7 ± 5.98 Kg/m2 e média de peso 72,78 ±12.7 Kg e 65,94 ± 15.4 Kg para o sexo masculino e feminino, respectivamente. A porcentagem de massa magra foi maior nos homens (p=0,0008) e de gordura corporal, maior no sexo oposto (p=0,0006)...

Reference distribution of the bioelectrical impedance vector in healthy term newborns.

Bioelectrical impedance vector analysis (BIVA) is a new method that is used for the routine monitoring of the variation in body fluids and nutritional status with assumptions regarding body composition values. The aim of the present study was to determine bivariate tolerance intervals of the whole-body impedance vector and to describe phase angle (PA) values for healthy term newborns aged 7-28 d. This descriptive cross-sectional study was conducted on healthy term neonates born at a low-risk public maternity. General and anthropometric neonatal data and bioelectrical impedance data (800 µA-50 kHz) were obtained. Bivariate vector analysis was conducted with the resistance-reactance (RXc) graph method. The BIVA software was used to construct the graphs. The study was conducted on 109 neonates (52.3% females) who were born at term, adequate for gestational age, exclusively breast-fed and aged 13 (SD 3.6) d. We constructed one standard, reference, RXc-score graph and RXc-tolerance ellipses (50, 75 and 95%) that can be used with any analyser. Mean PA was 3.14 (SD 0.43)° (3.12 (SD 0.39)° for males and 3.17 (SD 0.48)° for females). Considering the overlapping of ellipses of males and females with the general distribution, a graph for newborns aged 7-28 d with the same reference tolerance ellipse was defined for boys and girls. The results differ from those reported in the literature probably, in part, due to the ethnic differences in body composition. BIVA and PA permit an assessment without the need to know body weight and the prediction error of conventional impedance formulas.

The association of lipodystrophy and oxidative stress biomarkers in HIV-infected men.

The aim of this study was to describe the status of oxidative stress and antioxidant biomarkers and their association with metabolic and body composition components of HIV-lipodystrophy syndrome. In a cross-sectional study of blood samples from HIV-infected men with lipodystrophy syndrome (HIV+LIPO+ = 10), HIV-infected men without lipodystrophy syndrome (HIV+LIPO- = 22), and healthy subjects (control = 12), the following oxidative stress biomarkers were analyzed: total hydroperoxide, thiobarbituric acid reactive substances (TBARS), and advanced oxidation protein products (AOPP). In addition, antioxidant biomarkers, including total glutathione, uric acid, alpha-tocopherol, and metabolic components were tested. Dual-energy x-ray absorciometry (DXA) was used to measure the fat mass. The duration of HIV infection and the duration and type of highly active antiretroviral therapy were similar between the two HIV-infected groups. Higher levels of total hydroperoxide were observed in the HIV+LIPO+ (50 +/- 33 H(2)O(2)/L) group compared to the HIV+LIPO- (19 +/- 13 H(2)O(2)/L) and control (5 +/- 5 H(2)O(2)/L) groups (p < 0.05). Similarly, higher levels of AOPP were observed in the HIV+LIPO+ (326 +/- 173 micromol/L) group compared to the HIV+LIPO- (105 +/- 92 micromol/L) and control groups (80 +/- 20 micromol/L) (p < 0.05). Total hydroperoxide significantly correlated with insulin serum levels in the HIV+LIPO+ (r = 0.47, p < 0.05) and HIV+LIPO- groups (r = 0.29, p < 0.05), while AOPP significantly correlated with insulin serum levels in the HIV+LIPO+ (r = 0.73, p < 0.05) and HIV+LIPO- (r = 0.54, p < 0.05) groups. Therefore, higher lipid and protein oxidation were found in HIV-infected patients with lipodystrophy syndrome, and both were associated with insulin levels.

Can an adequate energy intake be able to reverse the negative nitrogen balance in mechanically ventilated critically ill patients?

PURPOSE: Adequate energy provision and nitrogen losses prevention of critically ill patients are essentials for treatment and recovery. The aims of this study were to evaluate energy expenditure (EE) and nitrogen balance (NB) of critically ill patients, to classify adequacy of energy intake (EI), and to verify adequacy of EI capacity to reverse the negative NB. METHODS: Seventeen patients from an intensive care unit were evaluated within a 24-hour period. Indirect calorimetry was performed to calculate patient's EE and Kjeldhal for urinary nitrogen analysis. The total EI and protein intake were calculated from the standard parenteral and enteral nutrition infused. Underfeeding was characterized as EI 90% or less and overfeeding as 110% or greater of EE. The adequacy of the EI (EI EE(-1) × 100) and the NB were estimated and associated with each other by Spearman coefficient. RESULTS: The mean EE was 1515 ± 268 kcal d(-1), and most of the patients (11/14) presented a negative NB (-8.2 ± 4.7 g.d(-1)). A high rate (53%) of inadequate energy intake was found, and a positive correlation between EI EE(-1) and NB was observed (r = 0.670; P = .007). CONCLUSION: The results show a high rate of inadequate EI and negative NB, and equilibrium between EI and EE may improve NB. Indirect calorimetry can be used to adjust the energy requirements in the critically ill patients.

Both human immunodeficiency virus-infected and human immunodeficiency virus-exposed, uninfected children living in Brazil, Argentina, and Mexico have similar rates of low concentrations of retinol, beta-carotene, and vitamin E.

Our objective was to describe the prevalence of low concentrations of retinol, beta-carotene, and vitamin E in a group of human immunodeficiency virus (HIV)-infected Latin American children and a comparison group of HIV-exposed, uninfected children. Our hypothesis was that the rates of low concentrations of these micronutrients would be higher in the HIV-infected group than those in the HIV-exposed, uninfected group. This was a cross-sectional substudy of a larger cohort study at clinical pediatric HIV centers in Latin America. Serum levels of micronutrients were measured in the first stored sample obtained after each child's first birthday by high-performance liquid chromatography. Low concentrations of retinol, beta-carotene, and vitamin E were defined as serum levels below 0.70, 0.35, and 18.0 micromol/L, respectively. The population for this analysis was 336 children (124 HIV-infected, 212 HIV-exposed, uninfected) aged 1 year or older to younger than 4 years. Rates of low concentrations were 74% for retinol, 27% for beta-carotene, and 89% for vitamin E. These rates were not affected by HIV status. Among the HIV-infected children, those treated with antiretrovirals were less likely to have retinol deficiency, but no other HIV-related factors correlated with micronutrient low serum levels. Low concentrations of retinol, beta-carotene, and vitamin E are very common in children exposed to HIV living in Brazil, Argentina, and Mexico, regardless of HIV-infection status.

Harris-Benedict equation for critically ill patients: are there differences with indirect calorimetry?

PURPOSE: The aim of this study was to compare the measured energy expenditure (EE) and the estimated basal EE (BEE) in critically ill patients. MATERIALS AND METHODS: Seventeen patients from an intensive care unit were randomly evaluated. Indirect calorimetry was performed to calculate patient's EE, and BEE was estimated by the Harris-Benedict formula. The metabolic state (EE/BEE x 100) was determined according to the following criteria: hypermetabolism, more than 130%; normal metabolism, between 90% and 130%; and hypometabolism, less than 90%. To determine the limits of agreement between EE and BEE, we performed a Bland-Altman analysis. RESULTS: The average EE of patients was 6339 +/- 1119 kJ/d. Two patients were hypermetabolic (11.8%), 4 were hypometabolic (23.5%), and 11 normometabolic (64.7%). Bland-Altman analysis showed a mean of -126 +/- 2135 kJ/d for EE and BEE. Only one patient was outside the limits of agreement between the 2 methods (indirect calorimetry and Harris-Benedict). CONCLUSIONS: The calculation of energy needs can be done with the equation of Harris-Benedict associated with lower values of correction factors (approximately 10%) to avoid overfeeding, with constant monitoring of anthropometric and biochemical parameters to assess the nutritional changing and adjust the infusion of energy.

Valores de referência de ingestão de nutrientes para avaliação e planejamento de dietas de crianças de um a oito anos / Dietary reference intakes for the evaluation and planning of diets for children aged one to eight years

Os valores de referência de ingestão dietética (Dietary Reference Intakes - DRIs) foram desenvolvidos para auxiliar no planejamento alimentar e avaliação da ingestão de nutrientes de indivíduos e populações. Foram propostos a partir do final da década de 90, em substituição às recomendações estabelecidas em 1989 (RDAs), visando a implementação de inovações como a criação de novos conceitos de avaliação e planejamento de dietas, devido à disponibilidade de informações atualizadas sobre necessidades e ingestão de nutrientes; o estabelecimento dos níveis máximos de ingestão com o surgimento do conceito de redução do risco de doenças crônico-degenerativas e a subdivisão dentro de cada faixa etária, devido às demandas diferenciadas de nutrientes para cada etapa da vida. Considerando a importância da avaliaçãodo consumo alimentar na atenção integral à saúde da criança e a fim de subsidiar os profissionais de saúde no diagnóstico e acompanhamento nutricional, o objetivo deste trabalho foi apresentar de maneira prática as recomendações nutricionais e seu modo de aplicação em crianças de um a oito anos de idade baseando-se na metodologia das DRIs.

Dietary Reference Intakes (DRIs) have been developed in order to help dietary planning and the assessment of nutrient intake for individuals and populations. These values were proposed in the late nineties to replace the recommended daily allowances (RDAs), innovating and creating new concepts of dietary planning and assessment due to the recently updated information about nutrient requirements, the establishment of maximum intake levels in need to include the concept of risk-reduction of chronic-degenerative diseases, and a subdivision within each age range due to the different nutrient requirements in each stage of life. Considering the food consumption assessment important in full-range attention to the children’s health, and enabling funds to health professionals in nutritional monitoring and diagnosis, the main objective of the current study was to present, in a practice way, the nutritional recommendations and their applications for children aged 1 to 8 years old, based on the DRIs Methodology.

Modelo do estudo: Estudo de prevalência. Objetivo: A subnutrição é freqüentemente observada em crianças hospitalizadas e está associada a um pior prognóstico. A correta abordagem nutricional, incluindo a prescrição dietética, melhora a evolução clínica. O objetivo desse estudo foi avaliar a adequação da prescrição dietética em crianças hospitalizadas. Métodos: Vinte e uma crianças foram acompanhadas de Julho a Setembro de 2004. Foi realizado a avaliação das prescrições dietéticas de crianças recebendo nutrição enteral durante três períodos da internação. Resultados: Houve inadequação do peso durante a hospitalização (dia 1 =76.4 ± 18.2%; dia 2 = 76.1 ± 18.6%; dia 3 = 76.7 ± 19.6%), sem alteração durante o período do estudo. A prescrição energética foi inadequada, porém as de proteínas e micronutrientes apresentaram-se dentro da recomendação. Conclusão: A condição clínica pode afetar de maneira negativa a prescrição nutricional. A equipe multidisciplinar deve se empenhar ao máximo para atingir as necessidades energéticas das crianças hospitalizadas.

Background: Malnutrition is frequently found in hospitalized children and is associated with poor outcome. The adequate nutritional approach improves clinical evaluation.The aim of this study was to evaluate the adequacy of dietetic enteral order in hospitalized children. Methods: Twenty one children were followed from july to september 2004. The dietetic enteral orders were registered during three periods of hospitalization. Results: The children body weight was inadequate and didn´t changed during the hospitalization (day 1 = 76.4 ± 18.2%; day 2 = 76.1± 18.6%; day 3 = 76.7 ± 19.6%). Energy dietetic order was inadequate but protein and micronutrients were according to the recommendation. Conclusion: Clinical condition may negativelly affect the nutritional order. The multidisciplinary team should give all the efforts to meet the appropriate dietetic energy order of hospitalized children.
