RESUMEN
OBJECTIVE: To describe the results of a nutritional intervention programme among Japanese-Brazilians according to gender. DESIGN: A non-controlled experimental study. SETTING: The research included three points of clinical, nutritional and physical activity evaluation: at baseline (in 2005), after the first year and at the end of the second year (in 2007). The paired Student t test and multiple linear regression analysis were used to evaluate changes in the subjects' profile (clinical, nutritional and physical activity variables). SUBJECTS: Japanese-Brazilians (n 575) of both genders, aged over 30 years. RESULTS: We verified statistically significant reductions in body weight (0.9 kg), waist circumference (2.9 cm), blood pressure, fasting blood glucose (>3 mg/dl) and total cholesterol (>20 mg/dl) and its fractions, in both genders. We also found reductions in intake of energy (among men), protein (among women) and fat (both genders) and increases in intake of total fibre (among women) and carbohydrate (among men). CONCLUSIONS: The intervention programme indicated meaningful benefits for the intervention subjects, with changes in their habits that led to a 'healthier' lifestyle positively impacting their nutritional and metabolic profile.

This study aimed to verify which anthropometric measure of abdominal obesity was the best predictor of all-cause and cardiovascular mortality in Japanese-Brazilians. The study followed 1,581 subjects for 14 years. Socio-demographic, lifestyle, metabolic, and anthropometric data were collected. The dependent variable was vital status (alive or dead) at the end of the study, and the independent variable was presence of abdominal obesity according to different baseline measures. The mortality rate was estimated, and Poisson regression was used to obtain mortality rate ratios with abdominal obesity, adjusted simultaneously for the other variables. The mortality rate was 10.68/thousand person-years. Male gender, age > 60 years, and arterial hypertension were independent risk factors for mortality. The results indicate that prevalence of abdominal obesity was high among Japanese-Brazilians, and that waist/hip ratio was the measure with the greatest capacity to predict mortality (especially cardiovascular mortality) in this group.

OBJECTIVE: We evaluated the changes in biochemical and nutritional profiles of Japanese-Brazilians with and without metabolic syndrome after two years of participation in the intervention program. MATERIALS AND METHODS: It was a non-controlled experimental study. The biochemical and clinical assessments were conducted at baseline (2005), after a year (2006) and after two years (2007) of intervention. On the present study, data of 360 individuals, who participated on the three assessments were considered. RESULTS: Both groups presented improvements on the anthropometric and metabolic profile, after two years of intervention. It was observed reduction in the intake of total fat, saturated fat, and dietary cholesterol, and increased intake of fiber among men without metabolic syndrome. It was observed reduction in the intake of total fat (p = 0,003) and monounsaturated fatty acid (p = 0,002). CONCLUSION: The results showed a positive impact of the lifestyle intervention program in metabolic and nutritional profile of Japanese-Brazilians with and without metabolic syndrome.

O objetivo foi verificar qual medida antropométrica de obesidade abdominal melhor prediz mortalidade geral e por doenças cardiovasculares entre nipo-brasileiros. Foram seguidos, por 14 anos, 1.581 sujeitos. Coletaram-se dados sociodemográficos, de estilo de vida, metabólicos e antropométricos. Considerou-se vivo ou óbito ao final do estudo como variável dependente e a presença de obesidade abdominal por diferentes medidas na linha de base como variável independente. Estimou-se o coeficiente de mortalidade e se usou o modelo de Poisson para obtenção das razões entre eles e a obesidade abdominal, ajustados simultaneamente às demais variáveis. O coeficiente de mortalidade foi de 10,68/mil pessoas-ano. O gênero masculino, a idade > 60 anos e ter hipertensão arterial foram fatores de risco independentes para mortalidade. Os resultados indicaram que entre nipo-brasileiros a prevalência de obesidade abdominal foi elevada e que a razão cintura quadril foi a medida que apresentou maior capacidade de predizer a mortalidade, especialmente cardiovascular, entre tais indivíduos.

OBJETIVO: Avaliar as mudanças nos perfis metabólico e nutricional de nipo-brasileiros com e sem síndrome metabólica, após dois anos de participação em programa de intervenção. MATERIAIS E MÉTODOS: Trata-se de estudo experimental não controlado. A pesquisa incluiu três momentos de avaliação clínico-laboratorial: basal (2005), após o primeiro ano de intervenção (2006) e ao final do segundo ano (2007). Na presente análise, utilizaram-se informações de 360 indivíduos examinados nos três momentos. RESULTADOS: Ambos os grupos apresentaram melhora no perfil metabólico e antropométrico, após o segundo ano de intervenção. Observaram-se diminuição na ingestão de gorduras totais, ácidos graxos saturados, colesterol e aumento de fibras totais nos homens sem síndrome metabólica. No sexo feminino sem síndrome metabólica, observou-se redução de gordura total (p = 0,003) e ácido graxo monoinsaturado (p = 0,002). CONCLUSÃO: Os resultados encontrados mostraram impacto positivo do programa de intervenção nos perfis metabólico e nutricional dos nipo-brasileiros com e sem síndrome metabólica.
