CI confidence interval
^aThe ‘other’ group includes Asian and indigenous individuals; because of the heterogeneity and small sample size of the ‘other’ group, we included only whites, browns, and blacks in our further analyses
^bThe estimates are based on the sample of 59,402 adults aged 18 years or older, considering the appropriate sampling weights
^bHypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg, and/or self-reported use of antihypertensive medications in the last 2 weeks (proportion of missing data of 1.0 %)
