Home Blood Pressure Monitoring in Women of Child-Bearing Age With Hypertension From 2009 to 2014

BACKGROUND Hypertension (HTN) is a leading cause of maternal mortality, and HTN guidelines recommend home blood pressure monitoring (HBPM) to help achieve blood pressure (BP) control. Evidence suggests that HBPM be coupled with a care team to maximize its effectiveness. HBPM use and the prevalence of provider counseling in child-bearing age women with HTN are unknown. METHODS We used data from 3,614 women in the cross-sectional National Health and Nutrition Examination Surveys 2009-2014 to determine HBPM use and provider counseling for women of child-bearing age (20-50 years) with and without HTN. HBPM use and provider counseling were self-reported. We examined rates of HBPM use by race/ethnicity, poverty-income ratio (PIR), education, and insurance. RESULTS Among women of child-bearing age with HTN, the mean (SE) age was 37.0 (0.3) years, the mean (SE) BMI was 35.5 (0.6) kg/m(2), and 73% were on BP medication. Of these women with HTN, 49.6% reported HBPM use in the past year and 40.4% received provider counseling. There was no significant difference in HBPM use by race/ethnicity, PIR, or insurance, though higher education was associated with HBPM use. Women with HTN who received provider counseling were more likely to use HBPM (odds ratio = 15.7, 95% confidence interval 9.1-26.9). CONCLUSIONS Nearly half of child-bearing age women with HTN have adopted HBPM, and provider counseling was strongly associated with HBPM use. This highlights a need and opportunity for providers to improve BP management by supporting a popular and valuable monitoring approach among women of child-bearing age with HTN.
