Summary of Definitions for Recommended Core Indicators
| Indicator | Numerator | Denominator |
|---|---|---|
| Core indicators | ||
| Mean systolic blood pressure | Sum of valid average systolic blood pressurea | Total number of respondents aged 18–69 y who had a valid blood pressure reading |
| Mean diastolic blood pressure | Sum of valid average diastolic blood pressurea | Total number of respondents aged 18–69 y who had a valid blood pressure reading |
| Prevalence of hypertension |
A) Respondents who have systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or who report currently taking medication for the treatment of high blood pressure B) Respondents who have systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or who report currently taking medication for the treatment of high blood pressure or who report having been diagnosed with hypertension by a health professional |
Respondents aged 18–69 y |
| Prevalence of awareness of hypertension | Respondents who report either having been diagnosed with high blood pressure or who report being currently treated with medication for high blood pressure | Respondents with hypertension according to definition A |
| Prevalence of treatment of hypertension | Respondents who report being currently treated with medication for high blood pressure | Respondents with hypertension according to definition A |
| Prevalence of controlled hypertension | Respondents who report being currently treated with medication for high blood pressure and have systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg | Respondents with hypertension according to definition A |
Standard deviations of mean systolic and diastolic blood pressure and 95% confidence intervals for the proportions should be calculated. Each of these core indicators can be reported overall and by age group (18–29 years, 30–49 years, and 50–69 years) and sex, with crude and age‐standardized (to the World Health Organization World Standard) changes tracked over time. Reporting core indicators among people with diabetes and among sociodemographic groups is recommended as expanded analyses. aIn WHO's STEPwise approach to surveillance (STEPS), average systolic and diastolic blood pressure are calculated from 2 of 3 blood pressure readings, taken 3 minutes apart, with preference given to the last 2 measurements.
