Abstract

Objectives: To verify factors associated with reaching goals in a lifestyle intervention program in Japanese-Brazilians living in Bauru, SP. Methodology: The factors associated with reaching the goals (5% of weight loss, practice of 150 minutes of physical activity/ week, less than 10% of energy from saturated fat and the intake of 400g of fruits and vegetables daily), after 12 months of intervention were investigated by adjusted logistic regression models. The assessments of lifestyle and health profile were conducted at baseline and after 12 months of intervention. Results: In total, 458 Japanese-Brazilians, 56% females, 84% of 2nd generation, mean (SD) age of 60 (11) were investigated. At baseline, 329 individuals were overweight, 278 reported less than 150 minutes/ week of physical activity, 107 reported food intakes with more than 10% of calories from saturated fat and 265 reported less than 400g of fruits and vegetables/day, and were included in the models. After 12 months, 11% of the overweight individuals reached the goal of weight loss, and 24, 55, and 16% of the participants reached the goals of the practice of physical activity, and intakes of saturated fat and fruits and vegetables, respectively. After adjustments for potential confounding variables, higher odds ratios [OR (95%)] for achieving weight loss were verified among women [2.4 (1.3; 4.5)], and lower chances among individuals with diabetes, hypertension or dyslipidemia [0.4 (0.1; 0.8)], and on precontemplation / contemplation stages of change for reducing red meat intakes [0.4 (0.2; 0.9)]. Individuals of 2nd generation had lower chances of achieving the goal of fruits and vegetables intake [0.3 (0.1; 0.9)]. No associations were verified for achieving the goals of practice of physical activity and saturated fat intakes. Conclusion: Among Japanese-Brazilians, the lifestyle intervention strategies were more efficient on reaching the goals among women, individuals of 1st generation, those without diseases and participants on stages of change of action/maintenance for reducing red meat intakes.
