The Association Between Cardiovascular Health with Internet and Mobile Technology Use Among Jackson Heart Study Participants Open Access
Sutton, Shandria (Spring 2021)
Abstract
Background: Cardiovascular disease (CVD) is a pervasive issue in the United States, as it is the leading cause of death in the country. African Americans are disproportionately impacted by this chronic disease, and they experience higher cardiovascular risk compared to other racial or ethnic groups. Current research has examined how effective technological interventions are in supporting CVD self-management and health information seeking. However, few of these studies have been conducted in populations of older, African Americans. Further research must be conducted to understand whether African Americans with or at risk for CVD use the internet and mobile technology, and if socioeconomic status affects this relationship, to understand if it is a feasible tool to help people obtain needed CVD-related information and utilize it to manage their cardiovascular risk.
Methods: The present study is a secondary data analysis using Jackson Heart Study data. Data were collected at three time points: Exam 1 (n=5,306), Exam 3 (n=3,819), and during the Digital Connectedness Survey (n=2,557). Participants completed measures of cardiovascular health (the American Heart Association’s Life simple 7), internet and mobile technology use, and demographic characteristics via telephone interview. Both multivariable logistic and linear regression analyses were conducted to analyze the relationship between Life’s Simple 7 composite scores (representing cardiovascular health) and internet and mobile technology use.
Results: Overall, 2, 255 (88%) of participants were IMT users. The association between LS7 composite scores and IMT use was non-significant (p<0.50). When analyzing the association between individual LS7 component scores and IMT use, glucose yielded the only significant result (p<0.01). Individuals in the ideal and intermediate categories for glucose control were more likely to be IMT users. In a model that included LS7 composite scores, socioeconomic status and the interaction between the two, the interaction did not have a significant effect on the relationship (p<0.83). The relationship between LS7 composite scores and IMT use characteristics was also mostly non-significant. The only significant association was between LS7 composite scores and use of smart devices (p<0.01). As LS7 scores increased (indicating better cardiovascular health), so did the odds of using smart devices such as smart phones, tablet computers, and smart watches.
Conclusions: The results failed to demonstrate an association between cardiovascular health and internet and mobile technology use. However, the study provided insight for areas of future research regarding cardiovascular health and internet and mobile technology use among older, African Americans.
