Examining the Relationship Between E-Cigarette Status and Wearable Device Use on Physical Activity Levels in U.S. Adults.

Purpose: The aim of this analysis is to investigate physical activity levels amongst e-cigarette users based on their wearable device use.

Design: Cross-sectional secondary data analysis using 2017 Behavioral Risk Factor Surveillance Survey (BRFSS).

Setting: Data from the 2017 BRFSS were used.

Sample: 5,562 U.S. adults (age 18+).

Measures: Self-reported physical activity related variables from U.S. adults (age 18+).

Analysis: Separate unadjusted and adjusted linear regression models were performed for each of the dependent variables using survey analysis.

Results: Non-users of wearable devices and e-cigarettes account for 96.6% (95%CI [95.7, 97.6]) of the sample, whereas users of wearable devices and e-cigarettes account for 3.3% (95%CI [1.2, 5.4]) of the sample. Those who use e-cigarettes participate in almost 50% less vigorous physical activity minutes per week than nonusers, 46 (95%CI [0.43, 91.57]) and 93 (95%CI [80.59, 106.34]) minutes respectively. Individuals who use e-cigarettes and use wearable devices were found to spend significantly more time in total physical activity per week in both the unadjusted and adjusted linear regressions, P = =0.01 and P = =0.04 respectively.

Conclusion: The use of e-cigarettes, wearable devices, or both technologies may influence the physical activity levels of its users. Additional research is needed to better understand the association between physical activity levels and the usage of these technologies.
