Abstract MP067: Reducing US Cardiovascular Disease Disparities Through Dietary Policy
Quantifying reductions in US cardiovascular deaths and disparities by different diet policies
Background: Large disparities exist in US dietary habits and cardiovascular disease (CVD) mortality. While economic incentives have demonstrated success in improving dietary choices, the quantitative impact of different dietary policies on CVD disparities is not well-established
Methods: Using a US IMPACT Food Policy Model and probabilistic sensitivity analyses, we estimated and compared the reductions in CVD mortality and disparities in the US population potentially achievable from 2015 to 2030 with specific dietary policy scenarios
a) a national mass media campaign (Media campaign) aimed to increase consumption of fruits and vegetables (F&V) or reduce sugar sweetened beverages (SSBs),
b) national fiscal policies to tax SSB and increase price by 10% and subsidize F&V to reduce prices by 10%; and
c) a targeted policy, to subsidize F&V to reduce prices by 30% among Supplemental Nutrition Assistance Programme (SNAP) participants only.
We also evaluated a combined multi-component approach, combining each of the above policies.
Results: Among individual policy options, a national 10% F&V subsidy was estimated to be most effective, resulting in approximately 150,500 (95% CI, 142,700-157,900) CVD deaths potentially prevented or postponed (DPPs) by 2030. This far exceed the approximately 35,100 (32,000-37,900) DPPs from a 30% F&V subsidy targeting SNAP participants, or some 23,000 (21,700-24,600) DPPs from a 1-year Media campaign or approximately 21,400 (19,500-23,600) DPPs from a 10% SSB tax.
Neither the Media campaign nor individual national economic policies would significantly reduce CVD disparities. However, the SNAP-targeted intervention would significantly reduce CVD disparities between SNAP participants and SNAP-ineligible individuals, by approximately 7% (10 DPPs per 100,000 population).
The combined policy approach would save more lives than any single policy studied (approximately 215,500 DPPs by 2030) while also significantly reducing disparities by approximately 5% (7 DPPs per 100,000 population).
Conclusions: Fiscal strategies targeting diet could reduce CVD burdens. A national 10% F&V subsidy would save by far the most lives, while a SNAP-targeted 30% F&V subsidy would most reduce disparities.
A combined policy would have the greatest overall impact on both mortality and disparities.
