National surveillance definitions for hypertension prevalence and control among adults.

ABSTRACT: BACKGROUND:Clear and consistent definitions of hypertension and hypertension control are crucial to guide diagnosis, treatment, and surveillance. A variety of surveillance definitions are in frequent use, resulting in variation of reported hypertension prevalence and control, even when based on the same data set. METHODS AND RESULTS:To assess the variety of published surveillance definitions and rates, we performed a literature search for studies and reports that used National Health and Nutrition Examination Surveys (NHANES) data from at least as recent as the 2003 to 2004 survey cycle. We identified 19 studies that used various criteria for defining hypertension and hypertension control, as well as different parameters for age adjustment and inclusion of subpopulations. This resulted in variation of reported age-standardized hypertension prevalence from 28.9% to 32.1% and hypertension control from 35.1% to 64%. We then assessed the effects of varying the definitions of hypertension and hypertension control, parameters for age adjustment, and inclusion of subpopulations on NHANES data from both 2007 to 2008 (n=5645) and 2005 to 2008 (n=10 365). We propose standard surveillance definitions and age-adjustment parameters for hypertension and hypertension control. By using our recommended approach with NHANES 2007 to 2008 data, the age-standardized prevalence of hypertension in the United States was 29.8% (SE, 0.62%) and the rate of hypertension control was 45.8% (SE, 4.03%). CONCLUSIONS:Surveillance definitions of hypertension and hypertension control vary in the literature. We present standard definitions of hypertension prevalence and control among adults and standard parameters for age-adjustment and population composition that will enable meaningful population comparisons and monitoring of trends.

Project description:IntroductionImproving hypertension control is a national priority. Electronic health record data have the potential to augment traditional surveillance systems. This study aimed to assess hypertension prevalence and control at the state level using a previously established electronic health record-based phenotype for hypertension.MethodsAdult patients (N=11,031,368) were included from the IQVIA ambulatory electronic medical record-U.S. 2019 data set. IQVIA ambulatory electronic medical record comprises electronic health records from >100,000 providers and includes patients from every U.S. state and Washington DC. Authors compared hypertension prevalence and control estimates against those from the Behavioral Risk Factor Surveillance System 2019. Results were age-standardized and stratified by state and sociodemographic characteristics. Statistical analyses were conducted in 2022-2023.ResultsIQVIA ambulatory electronic medical record-U.S. patients had a median age of 55 years, and 56.7% were women. Overall age-standardized hypertension prevalence was higher in IQVIA ambulatory electronic medical record-U.S. (35.0%) than in the Behavioral Risk Factor Surveillance System (29.7%), however, state-level geographic patterns were similar, with the highest burden in the South and Appalachia. Similar patterns were also observed by sociodemographic characteristics in both data sets: hypertension prevalence was higher in older age groups (than younger), men (than women), and Black patients (than other races). Hypertension control varied widely across states: among states with >1% data coverage, control rates were lowest in Nevada (51.1%), Washington DC (52.0%), and Mississippi (55.2%); highest in Kansas (73.4%), New Jersey (72.3%), and Iowa (71.9%).ConclusionsThis study provided the first-ever estimates of hypertension control for all states and Washington DC. Electronic health record-based surveillance could support hypertension prevention and control efforts at the state level.

Project description:BackgroundProviding an equitable Universal Health Coverage (UHC) is key for progressing towards the sustainable development goals in the health systems. To help policymakers make hypertension services more equitable with existing (limited) resources in Iran, we examined the inequality of the prevalence, awareness, treatment, and control (PATC) of hypertension as the four indicators of hypertension UHC in Iran. METHODS: This research was a cross-sectional study of inequality of PATC of hypertension using a representative sample of Iranians aged ≥ 25 years from the Iran 2016 STEP wise approach to Surveillance study (STEPS). Outcome variables consisted of PATC of hypertension. Covariates were demographic (age, sex, and marital status) and living standard (area of residence, wealth status, education, and health insurance) indicators. We drew concentration curves (CC) and estimated concentration indices (C). We also conducted normalized Erreygers decomposition analysis for binary outcomes to identify covariates that explain the wealth-related inequality in the outcomes. Analysis was conducted in STATA 14.1.ResultsThe normalized concentration index of hypertension prevalence and control was -0.066 (p < .001) and 0.082 (p < .001), respectively. The C of awareness and treatment showed nonsignificant difference between the richest and poorest. Inequality in the hypertension prevalence of females was significantly higher than males (C = -0.103 vs. male C = -0.023, p < .001). Our analyses explained 33% of variation in the C of hypertension prevalence and 99.7% of variation in the C of control. Education, wealth index, and complementary insurance explained most inequality in the prevalence. Area of residence, education, wealth status, and complementary insurance had the largest contribution to C of control by 30%, 28%, 26%, and 21%, respectively.ConclusionsThis study showed a pro-rich inequality in the prevalence and control of hypertension in Iran. We call for expanding the coverage of complementary insurance to reduce inequality of hypertension prevalence and control as compared with other factors it can be manipulated in short run. We furthermore advocate for interventions to reduce the inequality of hypertension control between rural and urban areas.

Project description:BackgroundPrevious studies suggest that having a marital partner with hypertension is associated with an individual's increased risk of hypertension, however this has not been investigated in sub-Saharan Africa despite hypertension being a common condition; the age-standardised prevalence of hypertension was 46.0% in 2013 in Namibia.ObjectiveTo explore whether there is spousal concordance for hypertension and hypertension control in Namibia.MethodsCouples data from the 2013 Namibia Demographic and Health Survey were analysed. Bivariable and multivariable logistic regression models were used to explore the odds of individual's hypertension based on their partner's hypertension status, 492 couples. and the odds of hypertension control in individuals based on their partner's hypertension control (121 couples), where both members had hypertension. Separate models were built for female and male outcomes for both research questions to allow independent consideration of risk factors to be analysed for female and males.ResultsThe unadjusted odds ratio of 1.57 (CI 1.10-2.24) for hypertension among individuals (both sexes) whose partner had hypertension compared to those whose partner did not have hypertension, was attenuated to aOR 1.35 (CI 0.91-2.00) for females (after adjustment for age, BMI, diabetes, residence, individual and partner education) and aOR 1.42 (CI 0.98-2.07) for males (after adjustment for age and BMI). Females and males were significantly more likely to be in control of their hypertension if their partner also had controlled hypertension, aOR 3.69 (CI 1.23-11.12) and aOR 3.00 (CI 1.07-8.36) respectively.ConclusionsHaving a partner with hypertension was positively associated with having hypertension among married Namibian adults, although not statistically significant after adjustment. Partner's hypertension control was significantly associated with individual hypertension control. Couples-focused interventions, such as routine partner screening of hypertensive individuals, could be developed in Namibia.
