  Figure 1. Life’s Simple 7 Health Score calculated using self-reported data for participants with and without registered digital health devices. The distribution of Life’s Simple 7 Health Scores is compared between individuals that did not register digital health devices (n = 1171) and those that did register digital health devices (n = 390) and presented as violin plots. The median and quartiles are denoted by dashed lines.

  Figure 2. Participant self-reported versus digital-health-device-measured weight and body mass index. Participant self-reported (a) weight and (b) calculated body mass index (BMI) are compared with weight measured by digital devices and BMI calculated using digital-health-device-measured weight. Data are summarized graphically in violin plots. Median and quartiles are denoted by dashed lines n = 292). (c) There are both increases and decreases in weight identified by digital health devices within the study population. The effect of a large difference in measured versus reported weight, change in Weight Score, and the resultant effect on Life’s Simple 7 Health Score is illustrated. Digital-device-measured weight was used to calculate body mass index (BMI) and a Life’s Simple 7 Weight Score. In 18 participants, the digital-device-measured BMI was significantly higher than the participant’s self-reported weight and the Weight Score decreased by one class. The digital health device Weight Score was used to calculate the Life’s Simple 7 Health Score. Thirteen participants overestimated their weight (and BMI) resulting in a better Weight Score and overall Life’s Simple 7 Health Score. LS7,…

  Figure 3. Self-reported exercise activity compared to digital-health-device-measured exercise activity. (a) Participant self-reported moderate and vigorous exercise minutes/week were compared with digital-device exercise moderate and vigorous exercise minutes per week and summarized graphically in violin plots. Median and quartiles are denoted by dashed lines, n = 355. (b) Digital-device-measured exercise (Ex) minutes (Min) per week were calculated. There are both increases and decreases in exercise minutes identified by digital health devices within the study population. The effect of a large difference in measured versus reported exercise, change in Activity Score, and change in Life’s Simple 7 Health Score is illustrated. In 74 participants, digital-device-measured exercise is less than reported exercise minutes and Activity Score and Health Score decreased. In 54 participants, the measured exercise minutes are higher than reported and the Activity Score and Health Score increased. LS7, Life’s Simple 7.

  Figure 4. Life’s Simple 7 Health Score based on digital health device data. Life’s Simple 7 Health Score calculated with digital-health-device-measured body mass index and exercise data was compared to the Life’s Simple 7 Health Score calculated with participant self-reported data. Results are summarized graphically in violin plots. Median and quartiles are denoted by dashed lines (n = 272).
