Personalized Behavioral Nutrition Among Older Asian Americans: Study Protocol

Area of Science:

• Metabolomics
• Nutritional Science
• Gerontology

Background:

• Metabolomics profiling objectively assesses metabolic responses to diet.
• Limited research exists on personalized behavioral nutrition (PBN) interventions using metabolomics for Type 2 diabetes in older Asian Americans.

Purpose of the Study:

• To describe the protocol for a pilot study.
• To test self-management of a nutrition intervention providing personalized dietary advice.
• To incorporate metabolite phenotypic feedback and digital self-monitoring for diet and blood glucose.

Main Methods:

• A pilot study will randomize 60 older Asian Americans into a PBN group and a control group.
• The PBN group will receive personalized dietary advice based on metabolic profiles and feedback.
• The study will examine the feasibility and preliminary effects of PBN on diabetes outcomes.

Main Results:

• Data collection was estimated to be complete by late 2021.
• The study began in September 2020.

Conclusions:

• Findings will guide future research on personalized nutrition interventions for Type 2 diabetes.
• This pilot study lays the groundwork for more effective diabetes management strategies.
