The serum soluble interleukin-2 receptor and interleukin-6 levels may be used as a noninvasive measure of celiac disease activity and response to treatment.
Objectives: To identify the prevalence of dyslipidemia in a group of 109 children and adolescents with a family history of premature coronary artery disease and to investigate the association between dyslipidemia and other risk factors for atherosclerosis.Methods: Total cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglycerides, body mass index, blood pressure, physical activity, smoking, per capita income and maternal schooling were investigated.Results: Total cholesterol and LDL-C levels were higher than desirable in 27.5% and 19.3%, respectively, of our patients; 13.8% had lower HDL-C values and 13.0% presented hypertriglyceridemia. Obesity and excess weight were observed in 25.7% of the cases. Out of these, 57.1% had abnormal lipid values. Dyslipidemia was observed in 38.5%, either alone or in combination with other risk factors. Smoking was observed in 3.6%, hypertension in 2.7% and physical inactivity in 72.5%. There was no relationship between dyslipidemia and per capita income, maternal schooling and physical inactivity. However, obesity and excess weight were identified as significantly associated with the occurrence of dyslipidemia (p = 0.02; odds ratio = 2.82, 95% CI = 1.6-6.81). Conclusion:In children and adolescents with a family history of premature coronary artery disease, early identification of the risk factors for atherosclerosis is essential to allow the implementation of preventive measures.
OBJETIVO: Estudar a prevalência da síndrome metabólica em adolescentes acompanhados em ambulatório de obesidade. MÉTODOS: Foram avaliados 84 adolescentes com idades entre dez e 19 anos, divididos em dois grupos, de acordo com o escore Z do índice de massa corpórea (Z IMC), sendo um o grupo de adolescentes com sobrepeso (GSP) e o outro, o grupo de adolescentes obesos (GOB). GSP: Z IMC>1 e <2 (1,6±0,2, 13M/13F), e GOB: Z IMC>2 (2,4±0,6, 32M/26F). Três ou mais dos critérios a seguir foram considerados no diagnóstico da síndrome metabólica e avaliados pelo teste do qui-quadrado entre os grupos: Z IMC>2; triglicérides em jejum >130mg/dL; lipoproteína de alta densidade <35mg/dL; glicemia em jejum >100mg/dL ou homeostatic model assessment index (HOMA) >2,5; elevação da pressão arterial acima do percentil 90 ajustada para gênero, estatura e idade. RESULTADOS: A prevalência da síndrome metabólica esteve significantimente elevada nos adolescentes obesos (GOB: 40% versus GSP: 4%, p=0,0008). O grupo GOB mostrou maiores valores referentes a insulinismo (54% versus 19%, p=0,003), HOMA (66% versus 38%, p=0,01) e trigliceridemia (21% versus 4%; p=0,04). CONCLUSÕES: É importante que o pediatra fique atento aos sinais de síndrome metabólica em adolescentes obesos. A detecção precoce pode ser feita por meio de simples parâmetros e permite a adoção de medidas preventivas para o desenvolvimento da doença cardiovascular em adolescentes.
In children and adolescents with a family history of premature coronary artery disease, early identification of the risk factors for atherosclerosis is essential to allow the implementation of preventive measures.
CONTEXT AND OBJECTIVE: The frequency of obesity at an early age may contribute to atherosclerosis and cardiovascular disease (CVD) in adults. This study measured the frequency of obesity and cardiovascular risk factors in children and adolescents aged 6 to 17 years. DESIGN AND SETTING: Cross-sectional study in a school located in a region of low income and socioeconomic status in Santa Rita do Sapucai, Minas Gerais, Brazil. METHODS: A total of 175 students were classified using body mass index (BMI) and their waist circumference, blood pressure, number of hours of sedentary behavior and school meals were evaluated. Serum concentrations of fasting blood glucose, total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) were analyzed. RESULTS: 37.2% of the students had BMI above the 85 th percentile and had significantly lower age, higher prevalence of hypertension, higher serum TC, LDL-C and TG, and greater waist circumference than those with BMI below the 85 th percentile. Hypertension was observed in 2.9% of the students; 5.1% presented impaired glucose tolerance, 40% had two risk factors for atherosclerosis and 26.9% had three risk factors. A sedentary lifestyle was significantly less prevalent among subjects with BMI above the 85 th percentile and was significantly correlated with serum TC and LDL-C. The school meals were hypoglycemic, hyperproteic and hyperlipidemic. CONCLUSION: One third of the children and adolescents had weights greater than or equal to the ageadjusted weight, and this was associated with greater waist circumference, hypertension and prevalence of dyslipidemia. RESUMOCONTEXTO E OBJETIVO: A frequência de obesidade em idade precoce pode contribuir para a aterosclerose e doença cardiovascular (DCV) em adultos. Este estudo mediu a frequência de obesidade e fatores de risco cardiovascular em crianças e adolescentes com idades entre 6 e 17 anos. TIPO DE ESTUDO E LOCAL:Estudo transversal em escola localizada numa região de baixa renda e baixo nível socioeconômico em Santa Rita do Sapucaí, Minas Gerais, Brasil. MÉTODOS: Um total de 175 alunos foi classificado pelo índice de massa corporal (IMC) e foram aferidas circunferência da cintura, pressão arterial, horas de sedentarismo e alimentação escolar. Realizaram-se dosagens séricas de glicemia de jejum, colesterol total (CT), triglicerídeos (TG), lipoproteína de baixa densidade (LDL-C) e lipoproteína de alta densidade (HDL-C). RESULTADOS: 37,2% dos alunos tinham IMC acima do percentil 85 e apresentaram idade significativamente menor, prevalência mais alta de hipertensão, CT sérico, LDL-C e TG elevados e maior circunferência abdominal em comparação com aqueles com IMC abaixo do percentil 85. Observou-se hipertensão em 2,9% dos estudantes, 5,1% apresentavam tolerância à glicose diminuída, 40% tinham dois fatores de risco para aterosclerose, e 26,9% tinham três fatores de risco. O sedentarismo foi significativamente menor em indivíduos com IMC acima do percentil 85 e foi significativamente...
