Impact of a 2-year intervention program on cardiometabolic profile according to the number of goals achieved.

We investigated the impact of lifestyle goal achievement on cardiovascular risk factors after a 2-year behavioral intervention program applied to 394 adults (113 with diabetes, mean age 60.2 ± 11.4 years, 56% women) and targeting four goals: ≥5% weight loss; ≥150 min/week physical activities; <10% saturated fat intake/day; ≥400 g fruit and vegetable intake/day. Baseline characteristics and changes in variables after intervention among the four categories of number of goals achieved (none, 1, 2, and ≥3) were compared by independent ANOVA or the Kruskal-Wallis test. Individuals without diabetes achieving a higher number of goals were more likely to be older (3 or 4 goals: 61.8 ± 12.6 years vs none: 53.3 ± 10.3 years, P < 0.05) and to have a lower mean BMI (3 or 4 goals: 21.7 ± 2.6 kg/m² vs none: 29.0 ± 4.8 kg/m², P < 0.05), diastolic blood pressure (3 or 4 goals: 77.3 ± 2.1 mmHg vs none: 85.4 ± 9.6 mmHg, P < 0.05), triglyceride (3 or 4 goals: 116.1 ± 95.1 mg/dL vs none: 144.8 ± 65.5 mg/dL, P < 0.05) and insulin levels (3 or 4 goals: 3.6 ± 2.4 µU/L vs none: 5.7 ± 4.0 µU/L, P < 0.05) than those achieving fewer goals. The absolute changes in cardiovascular risk factors tended to be more pronounced with increasing number of goals achieved in individuals without diabetes. The intervention had a beneficial impact on the cardiometabolic profile of individuals with normal or altered glucose metabolism. The number of goals achieved in this lifestyle intervention was associated with the magnitude of improvement of cardiovascular risk factors in individuals without diabetes. Participants with a better cardiometabolic profile seemed to be more likely to have a healthy lifestyle.

Impact of a 2-year intervention program on cardiometabolic profile according to the number of goals achieved

We investigated the impact of lifestyle goal achievement on cardiovascular risk factors after a 2-year behavioral intervention program applied to 394 adults (113 with diabetes, mean age 60.2 ± 11.4 years, 56 percent women) and targeting four goals: ≥5 percent weight loss; ≥150 min/week physical activities; <10 percent saturated fat intake/day; ≥400 g fruit and vegetable intake/day. Baseline characteristics and changes in variables after intervention among the four categories of number of goals achieved (none, 1, 2, and ≥3) were compared by independent ANOVA or the Kruskal-Wallis test. Individuals without diabetes achieving a higher number of goals were more likely to be older (3 or 4 goals: 61.8 ± 12.6 years vs none: 53.3 ± 10.3 years, P < 0.05) and to have a lower mean BMI (3 or 4 goals: 21.7 ± 2.6 kg/m² vs none: 29.0 ± 4.8 kg/m², P < 0.05), diastolic blood pressure (3 or 4 goals: 77.3 ± 2.1 mmHg vs none: 85.4 ± 9.6 mmHg, P < 0.05), triglyceride (3 or 4 goals: 116.1 ± 95.1 mg/dL vs none: 144.8 ± 65.5 mg/dL, P < 0.05) and insulin levels (3 or 4 goals: 3.6 ± 2.4 μU/L vs none: 5.7 ± 4.0 μU/L, P < 0.05) than those achieving fewer goals.

Fatores preditores do alcance das metas de um programa de intervenção em nipo-brasileiros / Predictors of goal achievement in an intervention program among Japanese-Brazilians

Identificar fatores da linha de base preditores do alcance das metas do programa de intervenção no estilo de vida após 12 meses em população de nipo-brasileiros, empregando-se modelos de regressão logística ajustados. Em 2005, 321 participantes eram portadores de excesso de peso e houve maior chance [OR (IC95 por cento)] de alcance da meta de perda de peso após 12 meses entre mulheres [2,45 (1,33; 4,13)], indivíduos de maior idade [1,03 (1,00; 1,06)] e menor chance entre portadores de morbidades no início do estudo [0,33 (0,14; 0,77)]. Dos 261 indivíduos sedentários, o alcance da meta de atividades físicas foi inversamente relacionado ao exercício de atividades profissionais [0,40 (0,17; 0,95)]. Não se verificou fatores da linha de base associados ao alcance das metas do consumo de legumes, verduras e frutas e gorduras saturadas da dieta após 12 meses. Indivíduos de maior idade, mulheres, não portadores de morbidades e sem exercício de atividades profissionais na linha de base apresentaram maior chance de alcance das metas após 12 meses de intervenção no estilo de vida.

The aim of this study was to identify baseline factors associated with achieving goals after a 12-month lifestyle intervention program in a Japanese-Brazilian population, using adjusted logistic regression models. In 2005, 321 participants were overweight. The odds [OR (IC95 percent)] of reaching the goals after 12 months of intervention were directly related to female gender [2.35 (1.34, 4.13)] and older age [1.03 (1.00, 1.06)] and inversely related to baseline morbidity [0.33 (0.14, 0.77)]. Of the 261 sedentary individuals, achieving the goal for physical activity was inversely related to working [0.44 (0.17, 0.95)]. No baseline predictors were found for reaching the goal of fruit and vegetable consumption or saturated fat intake after 12 months. At baseline, women, older individuals, and individuals without diseases or not working showed increased odds of achieving the goals after 12 months of the lifestyle intervention.

Prevalence and 7-year incidence of Type II diabetes mellitus in a Japanese-Brazilian population: an alarming public health problem.

AIMS/HYPOTHESIS: In 1993, the prevalence of glucose intolerance was studied in a sample of 647 first-generation and second-generation Japanese-Brazilians. Their cohort was followed until 2000, when a second survey was conducted, this included the first and second generations, aged 30 or more years. The aims were to estimate the prevalence of glucose intolerance and 7-yr incidence of Type II (non-insulin-dependent) diabetes mellitus in this population. METHODS: Prevalence rates were obtained for 1330 subjects examined in 2000. The incidence of diabetes mellitus was calculated for those classified as normal glucose tolerant in 1993 (n=253). A Student's t test and the Cox proportional hazard model were used in data analysis. RESULTS: In the year 2000, higher proportions of subjects were observed in all categories of glucose intolerance than those found in 1993. The overall incidence of diabetes was 30.9 per 1000 per year. A worse profile was observed among incident cases of diabetes, characterized by higher baseline values of anthropometric and metabolic variables as compared to those who had not developed diabetes. Analysis considering the simultaneous effects of demographic, nutritional and metabolic variables and physical activity levels for the development of diabetes showed that age, sex, waist circumference, fasting and 2-h plasma glucose concentrations were independent predictors. CONCLUSION/INTERPRETATION: Our data point towards a worsening of glucose tolerance status among Japanese-Brazilians, who show one of the highest prevalence rates of diabetes mellitus worldwide. This could reflect their strong genetic susceptibility associated with unfavourable environmental conditions.

Self-reported prevalence of non-insulin-dependent diabetes mellitus in the 1st (Issei) and 2nd (Nisei) generation of Japanese-Brazilians over 40 years of age.

The immigration of Japanese people to Brazil began in 1908 with two major waves, from 1925 to 1940 and from 1952 to the 1960s. Brazil has the largest population (about 1,288,000) of Japanese origin outside Japan with varying age groups. A mortality study revealed that diabetes as an underlying cause of death was higher in the first-generation Japanese than in Japan (3.4 vs. 1.9 per 100,000 for men, and 7.2 vs. 1.9 for women). The self-reported prevalences of known diabetes in subjects aged 40 years or older were obtained by questionnaires from three sources. In six Japanese cultural associations in Säo Paulo city, the prevalences were 9.7% and 6.9% for the first generation (mean age 61.5 years) and for the second generation (mean age 40.0 years), respectively. Age-adjusted prevalences, according to the Brazilian population in the 1980 national census, were 6.9% and 8.1% for the first and second generations. According to a study carried out as a part of a socioeconomic census of the Japanese population in Brazil, the prevalences of diabetes were 7.4% and 5.2%, and the age-adjusted prevalences were 5.3% and 5.8% in the first and second generations, respectively. Another study carried out for employees of a bank, owned by Japanese-Brazilian community members, revealed crude prevalences of diabetes in the first and second generations of 7.1% and 4.2%, and age-adjusted prevalences of 7.3% and 8.2%, respectively. These data indicate an increased prevalence of diabetes in this population compared to Japan, suggesting the importance of environmental factors in the pathogenesis of diabetes.
