Elevated Blood Pressure in Women of Childbearing Age in the United States.

PURPOSE Elevated blood pressure is frequently associated with adverse health issues among women during and after childbirth in the United States. The purpose of this study was to describe incidence of and determine predictors of prehypertension and hypertension among women of childbearing age in the United States. STUDY DESIGN AND METHODS Using secondary data analysis, existing data from the National Health and Nutrition Examination Survey (NHANES; 2013-2018) were used to address study aims. Inclusion criteria were women in the age range commonly considered to be of childbearing age, 15 to 44 years of age. Simple random sampling was to select subjects from the 2,932 women in the NHANES dataset who met inclusion criteria. We calculated a sample size as adequate for the statistical group comparison to be significant with a power of 95% to detect a difference among groups. An ordinal logistic regression model was created to discriminate predictors of normotensive blood pressure, prehypertension, and hypertension. RESULTS The sample (n = 393) included 300 women with normal blood pressure, 46 women with prehypertension, and 47 with hypertension. Older women (within childbearing age range), women with high body mass index, and African American women are highly likely to have prehypertension and hypertension. CLINICAL IMPLICATIONS Contrary to previous research, poverty income ratio was not associated with prehypertension and hypertension. Future research should test interventions that include promoting heathy lifestyles and address elevated body mass index. Interventions should be tailored to be culturally appropriate for African American women and older women within this age range.
