Study objective: This study aimed to evaluate the usability and feasibility of incorporating a cardiovascular risk assessment tool into adolescent reproductive health and primary care visits.
Design, setting, and participants: We recruited 60 young women ages 13-21 years to complete the HerHeart web-tool in 2 adolescent clinics in Atlanta, GA.
Main outcome measures: Participants rated the tool's usability via the Website Analysis and Measurement Inventory (WAMMI, range 0-95) and their perceived 10-year and lifetime risk of cardiovascular disease (CVD) on a visual analog scale (range 0-10). Participants' perceived risk, blood pressure, and body mass index were measured at baseline and 3 months after enrollment. Health care providers (HCP, n = 5) completed the WAMMI to determine the usability and feasibility of incorporating the HerHeart tool into clinical practice.
Results: Adolescent participants and HCPs rated the tool's usability highly on the WAMMI with a median of 79 (interquartile range [IQR] 65, 84) and 76 (IQR 71, 84). At the baseline visit, participants' median perceived 10-year risk of a heart attack was 1 (IQR 0, 3), and perceived lifetime risk was 2 (IQR 0, 4). Immediately after engaging with the tool, participants' median perceived 10-year risk was 2 (IQR 1, 4.3), and perceived lifetime risk was 3 (IQR 1.8, 6). Thirty-one participants chose to set a behavior change goal, and 12 participants returned for follow-up. Clinical metrics were similar at the baseline and follow-up visits.
Conclusion: HerHeart is acceptable to young women and demonstrates potential for changing risk perception and improving health habits to reduce risk of CVD. Future research should focus on improving retention in studies to promote cardiovascular health within reproductive health clinics.
