Abstract
Background: Although studies have examined if the internet and mobile technology (IMT) can support cardiovascular health (CVH) self-management and health information-seeking efforts, limited studies have targeted African American communities. This study analyzes a possible association between CVH and IMT use and if socioeconomic status is linked to this relationship among older, African Americans in the Jackson Heart Study (JHS). Methods: This analysis uses JHS data from three time points: Examination 1 (2000-2004), Examination 3 (2009-2013), and the Digital Connectedness Survey (2017-2019). Participants completed measures of CVH (the American Heart Association's Life Simple 7 [LS7]), IMT use, and demographic characteristics via telephone interview. Both multivariable logistic and linear regression analyses were conducted to analyze the relationship between the LS7 composite and component scores (representing CVH) and IMT use. Results: Fifty eight percent of participants were 60 or older; 64% were women. Overall, 2,255 (88%) of participants were IMT users. Generally, no association was found when analyzing LS7 composite scores and IMT use except for the association between LS7 composite scores and use of other smart devices (p = 0.01). However, having ideal blood pressure, body mass index, and cholesterol had positive associations with using technology to track health (p = 0.003, p = 0.004, p = 0.052, respectively), and having ideal physical activity was positively associated with using smart devices (p = 0.012). Conclusions: No association was found between LS7 composite scores and IMT use. However, there were associations between individual LS7 metrics, IMT use, and IMT use characteristics. More research should be done to continue assessing the feasibility of using IMT for CVH self-management among older African Americans.
