Effectiveness of an Eight Week Online Mediterranean Based Diet

6 mai 2022 mis à jour par: Linda Libertini, The Cleveland Clinic

Effectiveness of an Eight Week Online Mediterranean Based Diet in an Overweight or Obese Outpatient Primary Care Population

This research is examining whether an 8-week online nutritional programming based on a Mediterranean diet can achieve meaningful increase intake of a Mediterranean based diet and improvements in measures of body weight and laboratory measures of oxidative stress, a risk marker for cardiovascular disease. This study will also examine whether weekly short support and communication from a medical assistant (MA) in a primary care setting in addition to the online program will result in better program adherence and have a positive impact on health.

Aperçu de l'étude

Description détaillée

Eligible participants will be identified by primary care providers or their staff at clinical outpatient site(s). Study is 3-arm randomized control trial where participants will be randomized to 1) Control group (CTL)-will not receive access to online program nor intervention for first 12 weeks; 2) GFFY-1-will receive access to online program without MA intervention 3) GFFY-2-will receive access to online program and MA intervention with weekly phone call. The core of the intervention is an 8-week Mediterranean diet and behavioral online program called "Go! Foods for You (GFFY)" which is offered on the Cleveland Clinic's 360.5.com website. The research will last for 24 weeks. Questionnaire data and biometric measurements will be collected at pre and post intervention (0-8 weeks) and at followup (12 and 24 weeks). Regardless of randomization, participants will be asked to provide their weight every week and an activity log at the end of each week of the program. A urine sample to measure F2-isoprostane will be collected at week 0 and 12 for GFFY-2 and CTL groups.

A preparatory phase requiring the involvement of MAs to provide weekly support to participants is necessary to test process and communication with MAs. Enrollment of 10-20 volunteers for the preparatory phase is desired. Data collected during this phase will not be part of study analysis. To test data collection process, we may ask a few participants to complete baseline questionnaire only.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Aucune intervention: Control Group
No intervention provided. These participants will receive access to the Go! Foods for You program after the research trial has been completed (12 weeks after registration).
Comparateur actif: GFFY-1 without weekly MA support
Utilization of the 8-week online nutrition program Go! Foods for You without weekly contact from staff at the medical provider's office.
  • Participants access and utilize an 8-week online program which provides educational materials and weekly activities based on a Mediterranean diet and dietary "practices" that have been associated with healthy weights.
  • Each day participants receive educational materials related to the nutritional science of a Mediterranean diet. Each week (1) a new theme for the daily educational materials is presented and (2) participants are asked to schedule "activities" on a built in calendar and practice the activity throughout the week.
Comparateur actif: GFFY-2 with weekly MA support
Utilization of the 8-week online nutrition program combined with weekly contact from the staff at the medical provider's office.
  • Participants access and utilize an 8-week online program which provides educational materials and weekly activities based on a Mediterranean diet and dietary "practices" that have been associated with healthy weights.
  • In addition to the 8-week online program, participants receive weekly support by Medical Assistants (MA) over the phone or by email to establish a relationship and maintain program adherence by discussing the previous week's behavioral goals and setting weekly behavioral goals.
