Brief Summary

Understanding the impact of dietary patterns, exercise, and behavior change in the prevention of disease is paramount to improving the health and well-being of future generations and economies. A gap in the research is the lack of data on factors that predict successful behavior change for sustained dietary practices chosen for health or other personal reasons. To date, no survey exists that was designed to target persons following a wide range of popular dietary patterns (e.g., Paleo, low-carb, vegetarian, vegan, Mediterranean, gluten-free, etc.). These dietary patterns, which offer great variation in macronutrient composition, are unique and unexplored in other similar surveys to date, making their examination innovative. Adhering to Dietary Approaches for Personal Taste (ADAPT) will be the first large cohort of its type that is focused on adherence to popular dietary patterns, providing the opportunity to better understand how individuals can be supported to successfully maintain a specific dietary practice, and, in the long-term, how these practices may influence parameters of healthy aging.

Outcome Measures

Primary Outcomes (2)

  • Mean nutrient composition

    Compare actual intake calculated from participant-reported diet history questionnaires and/or diet recalls to targeted nutrient composition of the respective dietary pattern reported by the participant. Targeted nutrient composition will be calculated using 7-day meal plans from popular dietary patterns of interest. These 7-day meal plans will be generated from sources of nutrition information identified by participants in the ADAPT Feasibility Survey which was conducted in the summer of 2015 to demonstrate whether popular diet followers would be interested in participating in nutrition research.

    through study completion, approximately 1 year

  • Dietary adherence

    Adherence will be defined by self-report as follows: adhering to diet \> 95% of the time (high adherers), between 75-95% (moderate adherers); \< 75% time (lower adherers).

    through study completion, approximately 1 year

Secondary Outcomes (4)

  • Diet quality

    through study completion, approximately 1 year

  • Body weight

    through study completion, approximately 1 year

  • Body mass index (BMI)

    through study completion, approximately 1 year

  • Self-reported quality of life

    through study completion, approximately 1 year
