Objective: To assess the frequency of the hypertriglyceridemic waist phenotype and its associated factors in children and adolescents with type 1 diabetes mellitus. Methods: This is an observational analytical study with individuals with type 1 diabetes mellitus, aged 5 to 18 years, of both genders, followed in a university hospital in the Brazilian Northeast. Weight, height, and waist circumference were measured, and the lipid profile and glycated hemoglobin were analyzed. The hypertriglyceridemic waist phenotype was defined by the simultaneous presence of increased waist circumference (≥90th percentile for age and gender) and elevated serum triglyceride levels (≥75 mg/dL for children and ≥90 mg/dL for adolescents). We also investigated the family history of cardiovascular diseases and diabetes, as well as sociodemographic and behavioral variables. In the statistical inference tests, the proportions were compared by Pearson’s chi-square test and/or Fisher’s exact test, being significant p<0.05. Results: A total of 102 patients were evaluated, most of them females (54.9%) and adolescents (66.7%). The frequency of hypertriglyceridemic waist was 23.5%, which was associated with females (p=0.043), overweight (p=0.023), hypercholesterolemia (p=0.002), high LDL (p=0.001), and borderline VLDL (<0.001). Conclusions: The frequency of the hypertriglyceridemic waist phenotype was associated with females, atherogenic lipid profile, and overweight, indicating the importance of the nutritional monitoring of this population, aiming at reducing future cardiovascular diseases.
Objetivos: Investigar a associação entre a circunferência do pescoço (CP) e fatores de risco cardiovascular em crianças e adolescentes atendidos ambulatorialmente em um hospital universitário na cidade de Recife, PE, Brasil.Métodos: Foram coletados dados sociodemográficos, antropométricos, bioquímicos, histórico familiar e estilo de vida. A amostra foi por conveniência, composta por crianças e adolescentes acompanhados de seus responsáveis, que aceitassem participar da pesquisa, no período de abril a setembro de 2018, no ambulatório de nutrição/pediatria.Resultados: A amostra foi composta por 144 pacientes com idade média de 11,0±3,0 anos, sendo 73 do sexo masculino (51,4%). 54 (37,6%) pacientes apresentaram CP elevada, dentre eles 59 (41,1%) eram do sexo masculino. Foi visto que 102 (71,5%) pacientes apresentaram tempo de tela elevado. Houve associação entre CP e estado nutricional e 13 (24,8%) indivíduos que tinham CP elevada apresentaram também excesso de peso. Foi observado correlação entre circunferência do pescoço com índice de massa corporal e perfil lipídico.Conclusão: Observou-se que há associação significativa entre CP e algumas medidas antropométricas como IMC e CC, sendo útil para identificação de risco de sobrepeso e de risco cardiovascular. Algumas limitações no estudo podem ser citadas como o limitado número de participantes por ser uma pesquisa transversal, não podendo assim ser estabelecidas medidas de causa e efeito.
