Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: In a parallel group, randomized controlled trial, a total 414 individuals of East Asians aged over 60years will be allocated into one of three groups: 1 control and 2 intervention groups. Blood samples will be used for estimation of CHD genetic and analysis of metabolic risk markers. Genetic risk for CHD will be estimated based on recently identified 79 SNPs (associated with CHD for East Asians) using an established methodology. Questionnaires and physical measurement will be administered at Before and after the 12-month intervention and at 6-month follow-up. Each group will receive a Fitbit device. Both intervention groups will be given CHD genetic risk estimates along with lifestyle advice but one of them will additionally use Fitbit's step-goal setting and prompt functions. The primary outcome is objectively measured sedentary time. Secondary outcomes include objectively measured MVPA, calories burned, and five intermediate metabolic risk markers (total cholesterol/HDL-C/LDL-C/triglycerides).

Intervention Group - Genetic Risk Estimate+health coaching
Genetic: Genetic Risk Estimate The genetic risk information includes individual remaining-lifetime and 10-year genetic risk estimates for CHD 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). Health coaching will be incorporated as well.

The genetic risk information includes individual remaining-lifetime and 10-year genetic risk estimates for CHD 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). Health coaching will be incorporated through phone or Zoom calls to provide an explanation of each participant's own genetic risk of CHD as well as lifestyle modification measures.
Genetic Risk Estimate + Fitbit Functions+Health Coaching
Intervention: Device: Genetic Risk Estimate + Fitbit Functions The genetic risk information includes individual remaining-lifetime and 10-year genetic risk estimates for CHD as well as a dichotomized genetic risk category: 'increased genetic risk' or 'no increased genetic 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. Health coaching will be incorporated as well
