“…21 Therefore, the absence of an association in the active group could be mediated partially by the association between sport practice and better eating behaviors in adolescents. 21,23 In the present study, the relationship between inflammation and HDL-c could also explain the findings related to vascular structure in the active group. Physical activity of the group engaged in sports was marginally related to HDL-c, which modulates the phosphorylation of the endothelial nitric oxide synthase and would protect the artery wall through lower blood pressure.…”

Objective To analyze the relationship between inflammatory markers and the lipid profile, blood flow, and artery structure in prepubertal adolescents stratified according to sports practice. Study designThe sample was composed of 120 adolescents (57 boys and 63 girls) with a mean age of 11.7 AE 0.7 years (ranging from 11 to 13 years). Intima-media thickness (IMT) and blood flow were measured with ultrasonography. The lipid profile and high-sensitivity C-reactive protein were measured after the subjects had fasted for 12 hours overnight. Trunk fatness was measured by dual-energy x-ray absorptiometry. Organized sports participation was analyzed as a categorical variable. Biological maturation was determined via the age at peak height velocity.Results In the adjusted model, high-sensitivity C-reactive protein was significantly related to high-density lipopro- H igh-sensitivity C-reactive protein (hsCRP) is an acute-phase protein produced by the liver in response to interleukin-6, which is directly related to vascular inflammation.1,2 During the atherosclerotic process, hsCRP is associated with greater permeability of the intima layer through stimuli of intercellular/vascular cell adhesion molecules. hsCRP also acts in processes related to oxidation of lipoproteins in the vascular wall.2,3 Strategies to counteract inflammation status commonly include both pharmacologic and nonpharmacologic strategies. In the latter, lifestyle changes frequently are used, especially improved diet, giving up smoking, and practicing physical exercise. 4 Q5Indeed, physical exercise at moderate intensity plays an anti-inflammatory role. 4,5 Its prolonged practice has been linked to the control the progression of intima-media thickness (IMT) in hypertensive adults 6 and also in healthy adolescents. 7,8Recently, studies have reported that behavioral variables can modulate the relationship between the progression of artery IMT and its risk factors.9,10 For instance, smoking exacerbates the relationship between age and the metabolic syndrome components and age and carotid IMT (cIMT) in young adults. 10 In contrast, the same harmful effect related to age has been observed relating to physical inactivity.9 However, physical inactivity seems to exacerbate the relationship between cIMT Q6and overweight, blood pressure, and dyslipidemia in adults. 9The objective of the present study was to analyze the relationship between hsCRP and the lipid profile, blood flow, and artery IMT in prepubertal adolescents who were stratified according to their engagement in sports practice. It was hypothesized that inflammation would be positively and strongly related to cardiovascular/metabolic outcomes in inactive youth compared with the active ones, independent of body fatness and biological maturation.

RESUMOObjetivo: Analisar a influência dos componentes da síndrome metabólica na resistência à insulina, por sexo e fase da adolescência. Sujeitos e métodos: Avaliaram-se dados bioquímicos, clínico, de estilo de vida e composição corporal de 800 adolescentes de 10 a 19 anos, de ambos os sexos, de Viçosa-MG/Brasil, divididos em fases: inicial (10 a 13 anos), intermediária (14 a 16 anos) e final (17 a 19 anos). Resultados: 10,3 e 3,4% apresentavam, respectivamente, resistência à insulina e síndrome metabólica. Na fase inicial, observaram-se maior prevalência de dislipidemia e na intermediária, de hiperuricemia e excesso de gordura corporal. O sexo feminino apresentou maior prevalência de dislipidemia, excesso de gordura corporal e resistência à insulina e o masculino, maior prevalência de HDL baixo, hiperuricemia e pressão arterial alterada. Os da fase inicial apresentaram maiores valores de colesterol total, LDL, HDL, triglicerídeos, glicemia de jejum e relação cintura/quadril, ficaram menos tempo sentados e realizavam maior número de refeições (p < 0,05) em relação às outras fases. O modelo final, ajustado por sexo, foi diferente para cada fase da adolescência. Conclusões: A resistência à insulina está associada à inadequação na composição corporal, nos níveis bioquímicos e no estilo de vida, sendo os fatores associados diferentes em cada fase da adolescência. Arq Bras Endocrinol Metab. 2014;58(6):610-8 Descritores Resistência à insulina; composição corporal; adolescente; síndrome X metabólica ABSTRACT Objective: To analyze the influence of metabolic syndrome components in insulin resistance, by gender and adolescence phase. Subjects and methods: We evaluated biochemical, clinical, lifestyle and body composition data of 800 adolescents from 10 to 19 years old, from both genders, from Viçosa, MG/Brasil, and there was the division by stage: early (10 to 13 years), intermediate (14 to 16 years) and late (17 to 19 years). Results: 10.3 and 3.4% had, respectively, insulin resistance and metabolic syndrome. In the initial phase there was a higher prevalence of dyslipidemia and intermediate hyperuricemia and excess body fat. Females had a higher prevalence of dyslipidemia, excess body fat and insulin resistance and higher male prevalence of low HDL, hyperuricemia and blood pressure changes. Those from the initial phase had higher levels of total cholesterol, LDL, HDL, triglycerides, fasting glucose and waist/hip ratio, stayed less time sitting and had more meals (p < 0.05) in relation to other phases. The final model, adjusted for gender, was different for each phase of adolescence. Conclusions: Insulin resistance is associated with inadequate body composition, in biochemical levels and lifestyle, being the factors associated different in each phase of adolescence.
