BACKGROUND: Studies have suggested an association between the presence of acanthosis nigricans (AN) and the development of diabetes. OBJECTIVE: To investigate the association between AN and insulin resistance (IR) in overweight children and adolescents receiving care at the Center for Childhood Obesity, Campina Grande, PB. METHODS: This cross-sectional study was conducted between April 2009 and April 2010 including 194 individuals of 2 to 18 years of age receiving care within the Brazilian national health network. The presence of acanthosis nigricans was verified and anthropometric measurements were taken. The following tests were performed: insulin, triglycerides, HDL-cholesterol, glucose and homeostasis model of assessment -insulin resistance (HOMA-IR). Statistical analyses were performed using the SPSS software program, version 17.0. RESULTS: There was a greater prevalence of females (66%), brown-skinned individuals (63.4%), adolescents (61.3%) and severely obese individuals (66.5%). Acanthosis nigricans was identified in 58.2% and IR in 42.7% of the participants. Acanthosis nigricans was associated with being non-white (p = 0.003), with being an adolescent (p = 0.003) and with IR (p = 0.001). Non-white individuals, adolescents and those with insulin resistance were 5.4, 2.47 and 2.66 times more likely to have acanthosis nigricans, respectively. CONCLUSION: The results of this study indicate a need to train healthcare professionals to identify acanthosis nigricans, since this condition is associated with IR. Identifying acanthosis nigricans in childhood permits the safe and timely treatment of cardiometabolic disorders through careful monitoring and appropriate treatment. Keywords: Acanthosis Nigricans; Adolescent; Child; Insulin Resistance Resumo: FUNDAMENTOS: Estudos sugerem haver associação entre a presença de Acantose Nigricans e o desenvolvimento do diabetes. OBJETIVO: Verificar a associação entre Acantose Nigricans e Resistência Insulínica (RI) em crianças e adolescentes com excesso de peso, atendidos no Centro de Obesidade Infantil, Campina Grande-PB. MÉTODOS: Estudo transversal realizado entre abril/2009 a abril/2010, com amostra de 194 pessoas entre 2 e 18 anos, usuários do Sistema Único de Saúde. Na avaliação, foi observada a presença de AN e verificadas as medidas antropométricas. Foram realizados os exames: insulina, triglicerídeos, HDL-colesterol, glicose e HOMA-IR. As análises estatísticas foram realizadas no SPSS, 17.0. RESULTADOS: Houve maior prevalência do sexo feminino (66%), pardos (63,4%), adolescentes (61,3%) e obesos graves (66,5%). Foi identificada AN em 58,2% e RI em 42,7%. A Acantose Nigricans esteve associada à cor não-branca (p=0,003), adolescentes (p=0,003) e RI (p=0,001). Os não-brancos apresentaram chance de 5,4 vezes maior de terem Acantose Nigricans, os adolescentes, de 2,47 e os com Resistência Insulínica, de 2,66. CONCLUSÃO: Os resultados na população em estudo indicam a necessidade de treinamento voltado à identificação da Acantose Nigricans para profissionais de s...
OBJECTIVEIt has been argued that metabolically healthy obesity (MHO) does not increase cardiovascular disease (CVD) risk. This study examines the association of MHO with carotid intima-media thickness (cIMT), a proxy of CVD risk, in children and adolescents. RESEARCH DESIGN AND METHODSData were available for 3,497 children and adolescents aged 6-17 years from five population-based cross-sectional studies in Brazil, China, Greece, Italy, and Spain. Weight status categories (normal, overweight, and obese) were defined using BMI cutoffs from the International Obesity Task Force. Metabolic status (defined as "healthy" [no risk factors] or "unhealthy" [one or more risk factors]) was based on four CVD risk factors: elevated blood pressure, elevated triglyceride levels, reduced HDL cholesterol, and elevated fasting glucose. High cIMT was defined as cIMT ‡90th percentile for sex, age, and study population. Logistic regression model was used to examine the association of weight and metabolic status with high cIMT, with adjustment for sex, age, race/ethnicity, and study center. RESULTSIn comparison with metabolically healthy normal weight, odds ratios (ORs) for high cIMT were 2.29 (95% CI 1.58-3.32) for metabolically healthy overweight and 3.91 (2.46-6.21) for MHO. ORs for high cIMT were 1.44 (1.03-2.02) for unhealthy normal weight, 3.49 (2.51-4.85) for unhealthy overweight, and 6.96 (5.05-9.61) for unhealthy obesity. CONCLUSIONSAmong children and adolescents, cIMT was higher for both MHO and metabolically healthy overweight compared with metabolically healthy normal weight. Our findings reinforce the need for weight control in children and adolescents irrespective of their metabolic status.
200 mg/dL). Elas foram tratadas diariamente com 30 g da farinha da casca de maracujá por 60 dias. Após esse tempo foi observada uma redução estatisticamente significante (p < 0,05) nos níveis colesterol total (p = 0,00000) e colesterol LDL (p = 0,01193). Os resultados sugerem que a farinha da casca de maracujá seja utilizada na alimentação humana, juntamente com os alimentos, ou como matéria prima na produção de outros produtos, com o objetivo de reduzir o colesterol.]]>
Objective:to validate the content and appearance of a serial album for children aged from 7 to 10 years addressing the topic of prevention and control of body weight. Method:methodological study with descriptive nature. The validation process was attended by 33 specialists in educational technologies and/or in excess of infantile weight. The agreement index of 80% was the minimum considered to guarantee the validation of the material. Results:most of the specialists had a doctoral degree and a graduate degree in nursing. Regarding content, illustrations, layout and relevance, all items were validated and 69.7% of the experts considered the album as great. The overall agreement validation index for the educational technology was 0.88. Only the script-sheet 3 did not reach the cutoff point of the content validation index. Changes were made to the material, such as title change, inclusion of the school context and insertion of nutritionist and physical educator in the story narrated in the album. Conclusion:the proposed serial album was considered valid by experts regarding content and appearance, suggesting that this technology has the potential to contribute in health education by promoting healthy weight in the age group of 7 to 10 years.

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.
OBJECTIVE To investigate the association between C-reactive protein (CRP) and high blood pressure (BP) in overweight or obese children and adolescents. METHODS Cross-sectional study with 184 overweight or obese children and adolescents aged from two to 18 years old, from April, 2009 to April, 2010. The classification of nutritional status used the body mass index (BMI). Based on the Centers for Disease Control and Prevention curve, individuals were classified as: overweight (BMI between the 85th-95th percentiles), obesity (BMI between 95th-97th percentiles) and severe obesity (BMI >97th percentile). Abnormal values were considered for systolic BP (SBP) and/or diastolic (DBP) if ≥90th percentile of the BP curve recommended for children and adolescents in the V Brazilian Guidelines on Hypertension, for waist circumference (WC) if ≥90th percentile of the curve established by the National Cholesterol Education Program, and for high sensitive CRP (hs-CRP) if >3mg/dL. To evaluate the association of inadequate values of CRP and the studied groups, chi-square test and analysis of variance were applied, using the Statistical Package for the Social Sciences version 17.0 and adopting a significance level of 5%. RESULTS Among the evaluated sample, 66.3% were female, 63.5%, non-white, 64.1% had severe obesity, 78.3% had altered WC and 70.6% presented high BP. There was a significant association of CRP high levels with altered WC and BMI ≥97th percentile. In adolescents, high CRP was related to high SBP. CRP mean values were higher in individuals with elevated SBP. CONCLUSIONS Inadequate values of hs-CRP were associated with severe obesity and high SBP in the studied population. These markers can be used to identify children and adolescents at higher risk for developing atherosclerosis.
