Interventions
PATH Intervention
The PATH intervention guides participants in making changes in their lifestyle and PA habits to support long-term adherence to the minimum threshold of PA Guidelines (150 MVPA minutes per week). The health coach provides participants with access to the PATH website and a detailed orientation on how to use the resources included in PATH. The health coach meets remotely with each participant twice per month to develop a tailored plan geared towards increasing MVPA by about 10 minutes per week. The PA prescription process begins by identifying a suitable PATH level for each participant. After assigning the PATH level, the health coach guides each participant in selecting their weekly PA goal and helps them start slowly with a plan to establish regular exercise frequencies of 3-5 days per week. The coach also guides participants to select activities with intensity to help them progress along the PA continuum (i.e., from inactive to light PA and then MVPA).
Attention Control Intervention
A health coach will have a zoom meeting with each control group participant where they will be provided with an electronic copy of the "Be Active Your Way" booklet, developed by the Centers for Disease Control and Prevention (CDC) to help individuals integrate PA into their daily lives. The coach will orient the participants to the key strategies used in the booklet and encourage them to use it regularly and to self-monitor PA using the Fitbit during the entire course of the study. In addition, the group will be introduced to www.health.com, a jargon free website that focuses on general health topics and latest medical news. At the end of the meeting, the participants will be asked to provide a schedule for zoom meetings with the study team twice per month during the 6-month study. The meetings will focus on their progress in using the "Be Active Your Way" handout and the health.com website.
Physical activity tracker
Participants will be asked to wear Fitbit Charge 5 on their non-dominant hand for the entire duration of the study using a 24hr wear protocol.
Dietary education
Diet quality and barriers to healthy eating will be evaluated at baseline, and then all study participants will be provided with educational materials that are curated to promote diet quality. Participants will receive a monthly email with a brief Portable Document Format (PDF) addressing a diet component focused on improving diet quality to reduce CVD risk and improve general health.
