Abstract 076: Factors Associated With Home Blood Pressure Monitoring Among US Adults: The National Health and Nutrition Examination Survey (NHANES), 2013-2014

Abstract

Introduction: National prevalence data on home blood pressure monitoring (HBPM) has previously been reported from 2009-2010, but no recent data has been reported. Methods: This report is based on national-level, cross-sectional data for noninstitutionalized US adults aged ≥18 years (n = 6,113 participants) from the National Health and Nutrition Examination Survey (NHANES), 2013-2014. Results: Overall, 25.5% (1560 of 6113) of the adults engaged in HBPM monitoring in the 2013-2014 survey year. This is an increase from the previous NHANES 2009-2010 analysis reporting a 21.7% (1302 of 6001) rate. The frequency of HBPM increased with higher age, higher education level, having a partner, hypertensive, hypertensive aware, and hypertensive treated. Both SBP and DBP were higher in the HBPM group and were both statistically significant. The groups of hypertensive, hypertensive-aware, and hypertensive-treated patients all showed higher rates of HBPM use than nonuse. The frequency of HBPM monitoring in the categories of less than monthly, monthly, and weekly was reported at rates of 7.8% (476 of 6113), 6.6% (401 of 6113), and 11.2% (683 of 6113), respectively. These reported rates are consistent and slightly increased in the weekly HBPM reported use compared with the NHANEs 2009-2010 analysis (7.2% [432 of 6001], 6.6% [396 of 6001], and 7.9% [474 of 6001), respectively). Adjusting for covariables, those who were aware of, treated for, and had known hypertension were more likely to have a higher frequency of HBPM than the reference: unaware, untreated, and no known hypertension (odds ratio (OR) = 1.98; OR = 2.13; and OR = 1.64, respectively). Individuals with less than a high school diploma and having no partner were less likely to perform HBPM than the reference: high school graduate or greater and having a partner (OR = 0.73; OR = 0.65, respectively). Conclusions: Approximately 21.0% (1084 of 6113) of adults engaged in monthly or more frequent HBPM which is an increase from the reported 14.5%(870 of 6001) rate in the 2009-2010 analysis. Having hypertension, being aware of hypertension, and being treated for hypertension were associated with an increased frequency of HBPM. Having no partner and less than a high school diploma were associated with lower frequency of HBPM.
