Prevalence of overweight and obesity among Japanese-Brazilian: comparison across sex and generation
Keywords:
Abdominal circumference, Body mass index, Transients and migrants, Obesity, OverweightAbstract
Objective
To describe the prevalence of overweight, obesity and abdominal obesity in Japanese-Brazilians living in Bauru city, São Paulo State, Brazil.
Methods
Data were from a cross-sectional population-based study of 1.330 Japanese-Brazilians from the first and second generation of both genders and aged ≥30 years. Overweight and obesity criteria were body mass index of 25-29.9kg/m2 and ≥30kg/m2, respectively. Abdominal obesity was classified by waist circumference ≥90cm for men and ≥80cm for women. Point and 95%-confidence-interval prevalences were calculated for overweight, obesity and abdominal obesity.
Results
In the first generation of Japanese-Brazilians, 26.1% of men and 27.9% of women were overweight in comparison with 44.8% e 32.5% in the second generation for males and females, respectively. The prevalence of obesity was 3.7% and 12.0% in males and 6.6% and 9.9% in females respectively for the first and second generation. Overweight and obesity rates for men increased between generations, even though the differences were not statistically significant. Abdominal obesity in first and second-generation men was 32.1% and 45.3% respectively and among women these rates were 49.2% and 48.5%, respectively. The increased prevalence
of overweight and abdominal obesity in the study period was not statistically significant (p<0.05).
Conclusion
The high rates of overweight and central obesity among the Japanese-Brazilians immigrants can be partly explained by the westernization process. There is a strong need for preventive measures that minimize the metabolic consequences of excess weight in Japanese-Brazilians.
