The table shows the association obtained from Poisson regression models with robust standard errors separately by sex and self-recognized ethnicity. PRs and 95% CI were adjusted by age, location, income, home cooking with solid fuels, body mass index, waist circumference, waist-to-hip ratio and handgrip adjusted by bodyweight. Bold values are statistically significant. Abbreviations: PR, prevalence ratio; 95% CI, 95% confidence interval.
