Food‐related implicit associations predict self‐reported eating behaviors and dietary habits in large US samples

Obesity (Silver Spring)Published Cross-sectional study

Authors' conclusion

Health-favoring implicit food-related associations uniquely contribute to healthier eating behaviors and dietary patterns. These health-favoring associations could be a promising, yet underrecognized, target to promote healthier diets in the United States.

Study context

Population
Two US samples from Project Implicit Healthtwo US samples
Participants
11,504 vs 12,128
Exposure
Palatable Food vs Acceptable Food
  • Palatable Foodn = 11,504
  • Acceptable Foodn = 12,128
Outcome
Implicit food-related associations and self-reported eating behaviors and dietary patterns
Methodological detailstwo US samples, Project Implicit Health, Implicit associations measured with Implicit Association Tests; linear and logistic regressions
  • Two US samples
  • Project Implicit Health
  • Implicit associations measured with Implicit Association Tests; linear and logistic regressions

Main finding

As reported in the abstract

  • Health-favoring implicit palatability and acceptability associations (one-sample t tests)
  • Implicit associations predicted healthier self-reported eating behaviors and dietary patterns independent of explicit responses

Observational data: associations, not effects.

Further findings

Inconsistent associations with socioeconomic indicators
