The effect of images of Michelle Obama's face on trick-or-treaters' dietary choices: A randomized control trial.


ABSTRACT:

Objective

To evaluate the microfoundations of a personality-inspired public health campaign's influence on minors.

Design

Multi-year randomized control trial.

Setting

Economics professor's front porch in New Haven, CT.

Participants

1223 trick-or-treaters in New Haven over three years; on average, 8.5 years old and 53% male (among children whose gender was identifiable).

Eligibility

Trick-or-treaters over the age of three that approached the house.

Intervention

Random assignment to the Michelle Obama side of the porch or the Comparison side of the porch.

Main outcome measure

Selection of fruit over candy.

Methods

Difference-in-means estimates.

Results

We estimate that viewing a photograph of Michelle Obama's face relative to control conditions caused children to be 19% more likely to choose fruit over candy.

Conclusions

Michelle Obama's initiative to reduce childhood obesity has influenced children's dietary preferences. Whether this influence extends beyond Halloween trick-or-treating in New Haven, CT on the porch of an economics professor requires further research.
