Demographic, spatial and temporal dietary intake patterns among 526 774 23andMe research participants.

ABSTRACT:

Objective

To characterise dietary habits, their temporal and spatial patterns and associations with BMI in the 23andMe study population.

Design

We present a large-scale cross-sectional analysis of self-reported dietary intake data derived from the web-based National Health and Nutrition Examination Survey 2009-2010 dietary screener. Survey-weighted estimates for each food item were characterised by age, sex, race/ethnicity, education and BMI. Temporal patterns were plotted over a 2-year time period, and average consumption for select food items was mapped by state. Finally, dietary intake variables were tested for association with BMI.

Setting

US-based adults 20-85 years of age participating in the 23andMe research programme.

Participants

Participants were 23an
