Estimated health impacts of reformulation resulting from Health Star Rating nutrition labelling in Aotearoa New Zealand.

ABSTRACT: We aimed to model the impact of product reformulation following adoption of the Health Star Rating (HSR) nutrition labelling system in Aotearoa New Zealand (NZ). Household panel data (2014-19) was used to estimate the effect of HSR labels on product nutrient content. Observed changes were applied to population dietary intakes. Impacts were modelled through to Health Adjusted Life Years (HALYs) and health sector costs (NZ$2011 consumer price index (CPI) adjusted to NZ$2023) using a proportional multi-state life-table (pMSLT) model over the remaining life of the 2011 NZ population (n = 4.4 million, 3% discounted). Modelling the current HSR uptake (23% products on average), NZ adults' mean daily energy, sodium and fibre intakes changed by 0.7 KJ (0.0%), -18.2 mg (-0.5%) and 0.04 g (0.2
