Abstract 16827: Workplace Digital Health Intervention Improves Cardiovascular Risk Factors Over One Year Dependent Upon Participation
Emerging employer-sponsored work health programs (WHP) and digital health interventions (DHI) provide monitoring and guidance based on participants’ health risk assessments to ameliorate cardiovascular disease (CVD), but with uncertain success.
Hypothesis: We hypothesized that DHI, implemented as a WHP, would improve CVD risk factors over one year.
Methods: We analyzed participant (n=30,974) data from multiple worksites stratified by participation categorized as no (n=14,173), low (<26/yr, n=14,441), or high (>26/yr, n=2,390) log-ins, assessing changes in weight, waist circumference, BMI, blood pressure, lipids, and glucose at one year. We utilized ANOVA testing with Tukey’s post-hoc assessment as well as a linear regression model to analyze variables associated with increased participation.
Results: Those participating had similar ages (48.3±0.1 yrs) to non-participants (47.7±0.1 yrs) with a similar gender distribution. Significant improvements in BMI (-0.4±0.1, p<0.001), waist circumference (-0.7±0.1, p<0.001), triglycerides (-8.0±2.8, p=0.04), and HDL cholesterol (+1.4±0.5, p=0.001) were seen in high log-in users (Figure). Systolic blood pressure (-0.51±0.2, p=0.01) improved significantly in participants compared to non-participants. Multivariable linear regression demonstrated that level of participation in the DHI (measured by log-ins) was significantly associated with increasing age (p<0.001), female sex (p<0.001), high BMI (p<0.001), lower systolic blood pressure (p<0.001), elevated triglycerides (p=0.002), and high HDL (p=0.04).
Conclusions: DHI for WHP effectively reduces CVD risk factors in a large cohort of community-dwelling employees, with motivation possibly contributing to risk reduction. Furthermore, participants previously underrepresented in WHPs (females) or with an increased CVD risk factors including age, elevated BMI, and elevated triglycerides show increased adherence to this intervention.
