Full-scale Intervention Study: Genetic Risk Communication and Wearables

The genetic risk information includes individual remaining-lifetime and 10-year genetic risk estimates for T2D as well as a dichotomized genetic risk category: 'increased genetic risk' (if their genetic risk is higher than the average population risk) or 'no increased genetic risk' (if their genetic risk is not higher than the average population risk).

"The genetic risk information includes individual remaining-lifetime and 10-year genetic risk estimates for T2D as well as a dichotomized genetic risk category: 'increased genetic risk' (if their genetic risk is higher than the average population risk) or 'no increased genetic risk' (if their genetic risk is not higher than the average population risk).~The two unique Fitbit functions are step goal setting and prompts. Individualized daily step goals will be set to be 10% higher than participants' own baseline Fitbit step counts. The 'Reminder To Move' function of Fitbit will be used as a prompt to remind participants to reduce sedentary time and walk at least 250 steps/hour within a specified timeframe (i.e., from 9am to 10pm in the proposed research). If the user has not accumulated at least 250 steps/hour, a reminder (for example, 150 steps to go) will appear on the Fitbit screen at 10 minutes before the hour (for example, at 10:50 a.m.) and cause the device to vibrate."
