RESUMEN
Metabolic syndrome (MetS) is becoming prevalent in the pediatric population. The existing pediatric MetS definitions (e.g., the International Diabetes Federation (IDF) definition and the modified National Cholesterol Education Program (NCEP) definition) involve complex cut-offs, precluding fast risk assessment in clinical practice.We proposed a simplified definition for assessing MetS risk in youths aged 6-17 years, and compared its performance with two existing widely used pediatric definitions (the IDF definition, and the NCEP definition) in 10 pediatric populations from 9 countries globally (n = 19,426) using the receiver operating characteristic (ROC) curve analyses. In general, the total MetS prevalence of 6.2% based on the simplified definition was roughly halfway between that of 4.2% and 7.7% estimated from the IDF and NCEP definitions, respectively. The ROC curve analyses showed a good agreement between the simplified definition and two existing definitions: the total area under the curve (95% confidence interval) of the proposed simplified definition for identifying MetS risk achieved 0.91 (0.89-0.92) and 0.79 (0.78-0.81) when using the IDF or NCEP definition as the gold standard, respectively.The proposed simplified definition may be useful for pediatricians to quickly identify MetS risk and cardiometabolic risk factors (CMRFs) clustering in clinical practice, and allow direct comparison of pediatric MetS prevalence across different populations, facilitating consistent pediatric MetS risk monitoring and the development of evidence-based pediatric MetS prevention strategies globally.

AIMS: The clinical utility of waist-to-height ratio (WHtR) in predicting cardiometabolic risk factors (CMRFs) and subclinical markers of cardiovascular disease remains controversial. We aimed to compare the utility of WHtR with waist circumference (WC) and body mass index (BMI) in identifying children and adolescents (youths) at risk for cardiometabolic outcomes, including clustered CMRFs, high carotid intima-media thickness (cIMT), and arterial stiffness (assessed as high pulse wave velocity, PWV). METHODS: We analyzed data from 34,224 youths (51.0 % boys, aged 6-18 years) with CMRFs, 5004 (49.5 % boys, aged 6-18 years) with cIMT measurement, and 3100 (56.4 % boys, aged 6-17 years) with PWV measurement from 20 pediatric samples across 14 countries. RESULTS: WHtR, WC, and BMI z-scores had similar performance in discriminating youths with ≥3 CMRFs, with the area under the curve (AUC) (95 % confidence interval, CI)) ranging from 0.77 (0.75-0.78) to 0.78 (0.76-0.80) using the modified National Cholesterol Education Program (NCEP) definition, and from 0.77 (0.74-0.79) to 0.77 (0.74-0.80) using the International Diabetes Federation (IDF) definition. Similarly, all three measures showed similar performance in discriminating youths with subclinical vascular outcomes, with AUC (95 % CI) ranging from 0.67 (0.64-0.71) to 0.70 (0.66-0.73) for high cIMT (≥P95 values) and from 0.60 (0.58-0.66) to 0.62 (0.58-0.66) for high PWV (≥P95 values). CONCLUSIONS: Our findings suggest that WHtR, WC, and BMI are equally effective in identifying at-risk youths across diverse pediatric populations worldwide. Given its simplicity and ease of use, WHtR could be a preferable option for quickly screening youths with increased cardiometabolic risk in clinical settings.

BACKGROUND: Waist-to-height ratio (WHtR) has been proposed as a simple and effective screening tool for assessing central obesity and cardiometabolic risk in both adult and pediatric populations. However, evidence suggests that the use of a uniform WHtR cut-off of 0.50 may not be universally optimal for pediatric populations globally. We aimed to determine the optimal cut-offs of WHtR in children and adolescents with increased cardiometabolic risk across different countries worldwide. METHODS: We used ten population-based cross-sectional data on 24,605 children and adolescents aged 6-18 years from Brazil, China, Greece, Iran, Italy, Korea, South Africa, Spain, the UK, and the USA for establishing optimal WHtR cut-offs. We performed an external independent test (9,619 children and adolescents aged 6-18 years who came from other six countries) to validate the optimal WHtR cut-offs based on the predicting performance for at least two or three cardiometabolic risk factors. RESULTS: Based on receiver operator characteristic curve analyses of various WHtR cut-offs to discriminate those with ≥ 2 cardiometabolic risk factors, the relatively optimal percentile cut-offs of WHtR in the normal weight subsample population in each country did not always coincide with a single fixed percentile, but varied from the 75th to 95th percentiles across the ten countries. However, these relatively optimal percentile values tended to cluster irrespective of sex, metabolic syndrome (MetS) criteria used, and WC measurement position. In general, using ≥ 2 cardiometabolic risk factors as the predictive outcome, the relatively optimal WHtR cut-off was around 0.50 in European and the US youths but was lower, around 0.46, in Asian, African, and South American youths. Secondary analyses that directly tested WHtR values ranging from 0.42 to 0.56 at 0.01 increments largely confirmed the results of the main analyses. In addition, the proposed cut-offs of 0.50 and 0.46 for two specific pediatric populations, respectively, showed a good performance in predicting ≥ 2 or ≥ 3 cardiometabolic risk factors in external independent test populations from six countries (Brazil, China, Germany, Italy, Korea, and the USA). CONCLUSIONS: The proposed international WHtR cut-offs are easy and useful to identify central obesity and cardiometabolic risk in children and adolescents globally, thus allowing international comparison across populations.

To assess the effect of exergaming on the microcirculation function of adolescents with overweight or obesity, this non-randomized clinical trial efficacy was conducted with 61 adolescents aged between 10 and 16 years. The intervention group (n = 31) performed exergaming three times per week for 8 weeks. Both groups received guidelines for a healthy diet and staying physically active. Microcirculation was assessed using a laser Doppler flowmetry (LDF) at baseline and after intervention. Primary outcomes derived from LDF assessment included resting flow, maximum flow, maximum/resting flow ratio, area under hyperemia, and post-occlusive reactive hyperemia (PORH). Secondary outcomes were body mass index and systemic blood pressure. Unpaired Student's t test compared intergroup analyses, and paired Student's t test compared intragroup analyses. The significance was set at 5%. Statistical analysis intergroup and intragroup was done by fitting a two-way mixed effects model. Microcirculation was similar between groups. Maximum flow (109.0 ± 38.3 versus 124.6 ± 43.0, P = 0.022), area under hyperemia (1614 ± 472 versus. 1755 ± 461, P = 0.023), and PORH (2.18 ± 0.49 versus 2.01 ± 0.52, P = 0.031) were statistically different after intervention. Body mass index decreased in intervention (24.5 ± 3.8-24.1 ± 4.0 kg/m2, P = 0.002) and control (25.2 ± 3.2-25.1 ± 3.3 kg/m2, P = 0.031) groups. Systolic blood pressure decreased significantly in the intervention group (110 ± 10-106 ± 9 mm Hg; P = 0.041) but not diastolic blood pressure (66.0 ± 7-68.8 ± 8 mm Hg; P = 0.089). Exergaming for 8 weeks led to improvements in the microcirculation function in adolescents with overweighed or obesity. Clinical trials: NTC03532659.

ABSTRACT Objective To assess the association between breakfast omission, overweight/obesity, abdominal adiposity, and unhealthy lifestyle of low-income adolescents. Methods A cross-sectional population study involving 571 public school students aged between 15 and 19 years old. The habit of having breakfast was assessed using a form, checking the weekly frequency of a given meal and considered as breakfast omission when these adolescents did not have breakfast for at least 5 days in the past week. Sociodemographic and lifestyle variables (sedentarism, physical activity level, and sleep duration) were also assessed. Overweight/obesity was defined as a body mass index above a Z-score of +1, and the presence of abdominal adiposity was determined by a waist circumference/height ratio greater than 0.5. The association between breakfast omission and lifestyle variables was assessed using the chi-square test and a multivariate logistic regression of the anthropometric indicators. Results The omission of breakfast was found in 31% of the adolescents and was associated with physical inactivity (p<0.001). Regarding anthropometric indicators, breakfast omission was an independent factor for determining abdominal adiposity, with a 1.8 times greater chance of having this condition among those who omitted breakfast (p=0.037). Conclusions Omitting breakfast was frequent among the students assessed, and was associated with abdominal adiposity, a cardiometabolic risk factor. Investigation and early intervention are fundamental to change this behavior.
RESUMO Objetivo O estudo objetivou avaliar a associação entre omissão do desjejum, sobrepeso/obesidade, adiposidade abdominal e estilo de vida não saudável em adolescentes de baixa renda. Methods Este foi um estudo populacional com delineamento transversal, envolvendo 571 adolescentes de escolas públicas, entre 15 e 19 anos. O hábito do desjejum foi avaliado através de formulário que verificou a frequência semanal da realização dessa refeição, sendo considerado omissão do desjejum quando os adolescentes não o realizaram por pelo menos cinco dias na última semana. Variáveis sociodemográficas e de estilo de vida (sedentarismo, nível de atividade física e horas de sono) também foram analisadas. A classificação em sobrepeso/obesidade contemplou o índice de massa corporal acima do +1 escore-z, e definiu-se adiposidade abdominal quando a relação circunferência abdominal/estatura foi maior que 0,5. A associação entre a omissão do desjejum e as variáveis de estilo de vida foi avaliada através do teste do qui-quadrado e com os indicadores antropométricos por regressão logística multivariada Results O hábito de omitir o desjejum esteve presente em 31% dos adolescentes e apresentou associação com a inatividade física (p<0,001). Em relação aos indicadores antropométricos, a omissão do desjejum foi um fator independente para determinação da adiposidade abdominal, verificando-se uma chance 1,8 vezes maior de presença dessa condição entre os que omitiam o desjejum (p=0,037). Conclusions A omissão do desjejum foi frequente entre os estudantes avaliados e esteve associada à adiposidade abdominal, um fator de risco cardiometabólico, sendo fundamental a investigação e a intervenção precoce para a mudança desse comportamento.

OBJECTIVE: It 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 METHODS: Data 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. RESULTS: In 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. CONCLUSIONS: Among 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.

AIM: To report an analysis of the concept nursing care of overweight children. BACKGROUND: Patient care is the essence of nursing practice. Nursing professionals must define how to serve specific population groups, including overweight children, presenting real solutions to their problem. A clear conceptual analysis is necessary to unify nursing language and to contribute to nursing practice. DESIGN: Concept analysis. DATA SOURCES: The following databases were searched: COCHRANE, SCOPUS, LILACS, CINAHL, MEDLINE/PubMed, and CAPES Theses Library of Brazil. REVIEW METHODS: Walker and Avant's concept analysis methodology was adopted in this study. Twenty-two articles were analyzed, and the uses, attributes, antecedents, and outcomes of the concept were identified. The nursing care assumptions proposed by Virginia Henderson comprised the theoretical referential. RESULTS: The attributes of nursing care for overweight children included investigation, guidance, and monitoring of dietary, clinical, academic, and social aspects, along with evaluation of lifestyle and anthropometric data related to the affected children and their families. CONCLUSION: This study enabled the construction of a defined concept for nursing care of overweight children that may be useful in the construction of a medium-range theory. Further research is recommended to verify the usefulness of the nursing approach.

Contexto: Os benefícios para a saúde decorrentes da prática regular de atividade física estão bem documentados. Entretanto, são raros os estudos associando essa prática ao comportamento sedentário e ao risco cardiovascular em adolescentes. Objetivos: Pretende-se avaliar a prática de atividade física, o comportamento sedentário e a associação com o risco cardiovascular mensurado pelo escore Pathobiological Determinants of Atherosclerosis in Youth (PDAY). Métodos: Estudo transversal desenvolvido nas escolas públicas estaduais de Campina Grande, PB, Brasil, com 576 adolescentes de 15 a 19 anos, incluindo variáveis socioeconômicas, demográficas, de estilo de vida e clínicas. Os dados foram coletados através de formulário validado, antropometria, aferição da pressão arterial e exames laboratoriais. Foram utilizadas medidas descritivas, teste do qui-quadrado de Pearson e regressão logística binomial. Trabalhou-se com o SPSS 22.0 se adotou intervalo de confiança de 95%. Resultados: A idade média foi de 16,8 anos. A maioria dos adolescentes era do sexo feminino (66,8%), não branco (78.7%) e pertencente às classes C, D e (69,1%). Quanto ao sedentarismo e à insuficiência de atividade física, as prevalências foram de 78,1% e 60,2%, respectivamente. De acordo com o escore PDAY, 10,4% dos adolescentes apresentaram alto risco cardiovascular; 31,8% risco intermediário; e 57,8%, risco baixo. Verificou-se que PDAY esteve associado ao sexo e à adiposidade abdominal. Conclusões: Ficou comprovado que adiposidade abdominal e sexo masculino representam importantes fatores de risco cardiovascular em adolescentes. Considerando-se a presença de um fator de risco modificável, medidas preventivas voltadas ao estilo de vida são essenciais
Background: The health benefits of regular physical activity are well documented. However, there are few studies associating this practice with sedentary behavior and cardiovascular risk in adolescents. Objectives: To evaluate physical activity levels and sedentary behavior and their associations with cardiovascular risk using the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) score Methods: A cross-sectional study carried out in state-owned public schools in Campina Grande, PB, Brazil, with 576 adolescents aged 15 to 19 years, investigating socioeconomic; demographic; lifestyle; and clinical variables. Data were collected using a validated form covering anthropometry data; blood pressure measurements; and laboratory tests. Data were analyzed using descriptive statistics, Pearson's chi-square test, and binomial logistic regression using SPSS 22.0 and adopting a 95% confidence interval. Results: Mean age was 16.8 years. The majority of the adolescents were female (66.8%); non-white (78.7%); and belonged to socioeconomic classes C, D and E (69.1%). The prevalence rates of sedentary behavior and physical inactivity were 78.1% and 60.2%, respectively. According to the PDAY score, 10.4% of adolescents were at high cardiovascular risk and 31.8% and 57.8% were at intermediate risk and low risk, respectively. PDAY scores were associated with sex and abdominal adiposity. Conclusions: It was found that abdominal fat and being male were important cardiovascular risk factors in adolescents. Considering that modifiable risk factors were present, preventive measures aimed at lifestyle changes are essential

OBJECTIVE: to analyze the conditions that enhance the dimensions of individual, social and programmatic vulnerability associated with sexually transmitted infections in physically disabled people. METHODS: this transversal study, with a quantitative approach, was conducted in 2015 in conjunction with an association for disabled people in Campina Grande, PB, Brazil. Ninety-eight individuals participated in the study and answered a questionnaire regarding the dimensions of vulnerability in relation to sexually transmitted infections. The chi-square test, Fisher's test, contingency coefficient test and prevalence ratio test were all performed. RESULTS: an association was identified between the occurrence of sexually transmitted infections with the number of partners (p = 0.020); the belief that having few partners was a form of prevention (p = 0.044); the belief that poor hygiene was a risk factor; age (p = 0.007); the type of disability (p = 0.007); and having a consultation with a urologist (p = 0.030). CONCLUSION: physically disabled people have conditions that enhance their vulnerability to sexually transmitted infections, which are linked to individual, social and programmatic dimensions. By characterizing the conditions of vulnerability it is possible to devise specific prevention linked to the reality of the social and health conditions of individuals.

Resumo O objetivo deste artigo é analisar as condições que potencializam as dimensões de vulnerabilidade individual, social e programática associadas às infecções sexualmente transmissíveis em pessoas com deficiência física. Estudo transversal, com abordagem quantitativa, realizado em 2015, em uma associação para pessoas com deficiência de Campina Grande/PB, Brasil. Participaram 98 sujeitos que responderam um formulário sobre as dimensões de vulnerabilidade para infecções sexualmente transmissíveis. Realizaram-se os testes de Qui-quadrado, Fisher, Coeficiente de contingência e razão de prevalência. Verificou-se associação entre a ocorrência de infecções sexualmente transmissíveis com o número de parceiros (p = 0,020), acreditar em poucos parceiros como prevenção (p = 0,044), acreditar na má higiene como fator de risco, idade (p = 0,007), tipo de deficiência (p = 0,007) e realização de consulta com urologista (p = 0,030). As pessoas com deficiência física possuem condições que potencializam a vulnerabilidade para infecções sexualmente transmissíveis, atrelada às dimensões individual, social e programática. Por meio da caracterização das condições de vulnerabilidade é possível traçar uma prevenção específica atrelada a suas realidades individual, social e de saúde.

ABSTRACT Objective To assess sleep quality and its association with metabolic syndrome and its components. Methods This cross-sectional study was conducted from June 2011 to March 2012 at the Childhood Obesity Center, Campina Grande, Paraíba , Brazil, with 135 overweight or obese children and adolescents. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Metabolic syndrome diagnosis was based on abdominal circumference, blood pressure, glycemia, high density lipoprotein-cholesterol, and triglycerides. The data were treated by the software Statistical Package for the Social Sciences version 22.0 at a significance level of 5%. Results The prevalence of poor sleep quality or sleep disorder according to the Pittsburgh Sleep Quality Index was 40.7%, and females had higher mean global Pittsburgh Sleep Quality Index score. Metabolic syndrome prevalence was 63.0%. Females also had higher daytime dysfunction. Poor sleep quality was associated with high diastolic blood pressure (OR=2.6; p =0.015) and waist circumference (OR=3.17; p =0.024) after adjusting for sex and age. Conclusion Girls had higher global Pittsburgh Sleep Quality Index score, which was associated with daytime dysfunction. Poor sleep quality was a predictor of high diastolic blood pressure in the study sample.
RESUMO Objetivo Avaliar a qualidade do sono e sua associação com a síndrome metabólica e seus componentes. Métodos Estudo transversal, realizado entre junho de 2011 e março de 2012 no Centro de Obesidade Infantil, Campina Grande, Paraíba. Foram incluídas 135 crianças e adolescentes com sobrepeso ou obesidade. A qualidade do sono foi avaliada pelo Pittsburgh Sleep Quality Index. Para o diagnóstico de síndrome metabólica, consideraram--se circunferência abdominal, pressão arterial, glicemia, lipoproteínas de alta densidade e triglicerídeos. Os dados foram analisados pelo Statistical Package for the Social Sciences versão 22.0, sendo adotado um nível de significância de 5%. Resultados A prevalência de má qualidade ou distúrbio do sono avaliado pelo Pittsburgh Sleep Quality Index foi 40.7%, e a média do escore global Pittsburgh Sleep Quality Index foi significativamente maior no sexo feminino. A prevalência de síndrome metabólica foi 63.0%. A disfunção diurna foi significativamente maior no sexo feminino. A má qualidade do sono esteve associada à pressão arterial diastólica elevada (OR=2,6; p=0,015) e à circunferência abdominal elevada (OR=3,17; p=0,024), após ajuste para sexo e idade. Conclusão As meninas apresentaram um maior escore global do Pittsburgh Sleep Quality Index e associação com a disfunção diurna. A má qualidade do sono mostrou-se fator preditor de pressão arterial diastólica elevada na amostra estudada.

ABSTRACT OBJECTIVES: To determine the prevalence of increased serum fibrinogen levels and its association with cardiometabolic risk factors in overweight or obese children and adolescents. METHODS: Cross-sectional study with 138 children and adolescents (overweight or obese) followed at a reference outpatient clinic of the public health care network. Fibrinogen concentration was divided into quartiles, and values above or equal to the third quartile were considered high. The association between high fibrinogen values and cardiometabolic risk factors was assessed using Pearson's chi-squared test or Fisher's exact test, as necessary. Logistic regression was used to adjust variables predictive of fibrinogen levels. Analyses were performed using SPSS version 22.0 and SAS software, considering a confidence interval of 95%. RESULTS: Serum fibrinogen levels were elevated in 28.3% of individuals, showing association with the presence of high CRP (p = 0.003, PR: 2.41, 95% CI: 1.30-4.46) and the presence of four or more risk factors (p = 0.042; PR: 1.78, 95% CI: 1.00-3.17). After a logistic regression, only elevated CRP remained associated with altered fibrinogen levels (p = 0.024; PR: 1.32; 95% CI: 1.09-5.25). CONCLUSIONS: Increased fibrinogen was prevalent in the study population and was associated with ultrasensitive C-reactive protein and the presence of four or more cardiovascular risk factors; it should be included in the assessment of individuals at risk.
RESUMO OBJETIVOS: Verificar a prevalência de níveis séricos elevados de fibrinogênio e sua associação com os fatores de risco cardiometabólicos em crianças e adolescentes com sobrepeso ou obesidade. MÉTODOS: Estudo transversal com 138 crianças e adolescentes (obesos ou com sobrepeso) acompanhados em um ambulatório de referência da rede pública. A concentração do fibrinogênio foi distribuída em quartis e considerada elevada quando os valores eram iguais ou superiores ao terceiro quartil. A associação entre o valor elevado do fibrinogênio com os fatores de risco cardiometabólicos foi verificada com o teste qui-quadrado de Pearson ou o teste exato de Fisher, quando necessário. A regressão logística foi usada para ajuste das variáveis preditoras do nível do fibrinogênio. As análises foram feitas no SPSS 22.0 e SAS e considerou-se o intervalo de confiança de 95%. RESULTADOS: Os níveis séricos de fibrinogênio estiveram elevados em 28,3% dos indivíduos e apresentaram associação com a PCR elevada (RP: 2,41; IC95%: 1,30-4,46, p = 0,003) e com a presença de quatro ou mais fatores de risco (RP: 1,78; IC95%: 1,00-3,17; p = 0,042). Após a regressão logística, apenas o PCR elevado continuou associado ao fibrinogênio alterado (RP: 1,32; IC95% 1,09-5,25; p = 0,024). CONCLUSÕES: O aumento do fibrinogênio foi prevalente na população estudada, esteve associado à proteína C reativa ultrassensível e ao número igual ou superior a quatro de fatores de risco cardiovasculares e deve ser incluído na avaliação de indivíduos sob risco.

Objetivo: Verificar a associação dos fatores de risco cardiometabólicos com a medida da camada íntima-média da carótida em adolescentes com sobrepeso ou obesidade. Métodos: Estudo transversal envolvendo 32 adolescentes com idade de 10 a 20 anos com sobrepeso ou obesidade. Foram utilizadas variáveis sociais, antropométricas e laboratoriais (glicemia de jejum, insulina, índice de homeostase glicêmica da resistência insulínica, proteína C reativa ultrassenssível, fibrinogênio, colesterol total, lipoproteína de baixa densidade, lipoproteína de alta densidade e triglicerídeos) e a medida da espessura da camada média-intimal da artéria carótida comum (IMT). As variáveis foram descritas através de proporção, médias e desvio padrão. Foi realizada a distribuição das medidas da camada íntima-média da carótida em percentis e comparado os valores médios dos fatores de risco cardiometabólicos através do teste de ANOVA. Todas as análises foram realizadas com a versão 17.0 do programa SPSS, considerado o nível de significância de 5%. Resultados: A maioria dos avaliados apresentava obesidade e em aproximadamente um terço da amostra a medida da íntima-média da carótida se encontrava acima do percentil 75 para a idade e 37,5% apresentavam quatro ou mais fatores de risco cardiometabólico. Conclusões: A presença de espessamento da camada íntima média da carótida, um marcador precoce de aterosclerose subclínica e quatro ou mais fatores de risco cardiometabólicos em adolescentes com sobrepeso ou obesidade sinalizam a necessidade de medidas preventivas que consigam interromper a progressão da doença aterosclerótica.
