Health Star Rating Evaluation
The Health Star Rating (HSR) is a voluntary front-of-pack nutrition labelling system that was introduced to New Zealand and Australia in 2014. We will use our unique databases (annually-updated food labelling and composition data and nationally representative household food purchasing data) that span before and after introduction of HSR, to evaluate this policy. Using difference in difference fixed effects models and other natural experiment methods, we will measure the effects of HSR on population diets, through the pathways of: a) industry reformulation; and/or b) consumer food purchases
To measure the impact of voluntary front-of-pack nutrition labels (the Health Star Rating - HSR) on population diets.
The project will begin in March 2019
First results expected: 2020
