Cardiovascular risk in Japanese-Brazilian subjects

Objective: To evaluate the prevalence of risk factors for cardiovascular disease in Japanese-Brazilian subjects. Subjects and methods: One hundred thirty-one residents of the Mombuca community were studied. Statistical analysis was based on the X-2 test, Fisher's Exact test, Student's t test, and ANOVA, at a 5% significance level. Results: The average age was 56.7 years-old; 76.3% had dyslipidemia, 24.4% pre-diabetes (PDM), 10.7% type 2 diabetes mellitus (T2DM), 46.6% hypertension, 52.7% abdominal obesity, and 35.8% metabolic syndrome (MS). There were significant correlations between HOMA-IR and MS diagnosis and obesity, while HOMA-beta levels were decreased in T2DM and PDM. The ankle-brachial index was positive for peripheral artery disease in 22.3% of the individuals. Electrocardiograms did not show increased evidence of myocardial ischemia. Conclusion: Subjects of this community are exposed to major cardiovascular risk factors, namely high prevalence of MS diagnoses and increased HOMA-IR. Arq Bras Endocrinol Metab. 2012; 56(9): 608-13

Objetivo: Avaliar a presença de fatores de risco para doença cardiovascular em nipo-brasileiros. Sujeitos e métodos: Foram estudados 131 moradores de Mombuca. Utilizaram-se os testes do Qui-quadrado, Exato de Fisher, t de Student e ANOVA, com significância de 5%. Resultados: A média de idade foi de 56,7 anos; 76,3% tinham dislipidemia, 24,4% pré-diabetes (PDM), 10,7% diabetes melito tipo 2 (DM2), 46,6% hipertensão, 52,7% obesidade abdominal e 35,8% síndrome metabólica (SM). Houve correlação significativa do HOMA-IR com SM e obesidade, enquanto HOMA-b esteve reduzido na presença de DM2 e PDM. O índice tornozelo-braquial foi positivo para doença arterial periférica em 22,3% dos indivíduos. O eletrocardiograma não mostrou aumento de isquemia miocárdica. Conclusão: A comunidade está exposta aos fatores de risco maiores para doença cardiovascular, o que pode ser resumido pela alta prevalência de diagnóstico de SM e valores elevados de HOMA-IR.
