The authors analyzed HealthStyles surveys 2005 and 2008 combined to assess the prevalence of regular home blood pressure monitor (HBPM) use among hypertensive adults. All data were self-reported. The authors calculated odds ratios (ORs) of regular HBPM use and relative percent change (RPC) in the use of HBPM between the 2 survey years. There were 3739 (32.6%) hypertensives in the 2 survey years combined. Based on the self-reported data, the proportion of hypertensives who regularly used an HBPM was 43.2%. Male sex, age, race/ethnicity, household income, and education were all associated with differences in the prevalence of regular HBPM use. Patients 65 years and older (OR, 2.38; 95% confidence interval [CI], 1.49–3.81) were significantly more likely to be regular HBPM users than those 18 to 34 years. Non-Hispanic blacks were significantly less likely (OR, 0.69; 95% CI, 0.55–0.86) to be regular HBPM users than non-Hispanic whites. From 2005 to 2008, the RPC in regular HBPM use was 14.2% (from 40.1% to 45.8%); the largest RPCs were for the 3 youngest age groups, men, non-Hispanic blacks, and those with a household income of $40,000 to 59,900. Because HBPM has been demonstrated to aid in hypertension control, health care professionals should promote its use especially among hypertensives who are younger, non-Hispanic blacks, Hispanics, or with a lower income.
