Feasibility Survey

An initial ADAPT Feasibility Survey was successfully completed in July-September 2015, and nearly 14,000 individuals responded! This survey demonstrated the practicality of conducting research in populations of individuals consuming a variety of popular diets, including Paleo, low-carb, vegetarian, vegan, raw, Mediterranean, gluten-free, low-fat, and others. Our focus on popular dietary patterns is unique and unexplored in other similar cohort studies to date.

Although previous research has identified factors that drive people’s adherence to diets, including habit formation, social support, motivation, knowledge, and food preparation skills, these factors have not been largely studied in the context of wellness. No observational study has recruited individuals following a variety of self-identified diets to examine what facilitates adherence to these diets.

Preliminary Findings

Feasibility Survey Data -Body Mass Index (BMI)
Our analysis of mean body mass index (BMI) across diet groups found that members of most diet groups who had followed their diet for 1 year or more had a lower BMI than those members who had followed their diet for less than 1 year. There are many more questions to explore here, but this information indicates that following a specific diet may be helpful in achieving a healthy weight. We found statistically significantly lower mean BMIs among those on their diet for 1+ yrs in the following groups: “try to eat healthy”, whole food plant-based (WFPB), vegan, Paleo, whole food, and low-carb.
Feasibility Survey Data – Major Diet Groups

We were successful in capturing respondents eating a broad range of diets – from low-fat to high-fat and low-protein to high-protein. However, we did combine some similar diet groups in order to achieve large enough sample sizes within groups.

Feasibility Survey Data – Gender

Other studies have demonstrated that it is not uncommon to have more women interested in participating in nutrition research than men. Our first survey was no exception, with about 85% of respondents being female.

Feasibility Survey Data – Age Groups

We are happy to report that we did achieve a wide range of ages in our first survey.  Approximately one-third of respondents were over age 55.
