Objective To evaluate population health benefits and
cost-effectiveness of interventions for reducing salt in
the diet.
Design Proportional multistate life-table modelling of
cardiovascular disease and health sector cost outcomes
over the lifetime of the Australian population in 2003.
Interventions The current Australian programme of
incentives to the food industry for moderate reduction of
salt in processed foods; a government mandate of
moderate salt limits in processed foods; dietary advice
for everyone at increased risk of cardiovascular disease
and dietary advice for those at high risk.
Main Outcome Measures Costs measured in
Australian dollars for the year 2003. Health outcomes
measured in disability-adjusted life years (DALY) averted
over the lifetime.
Results Mandatory and voluntary reductions in the salt
content of processed food are cost-saving interventions
under all modelled scenarios of discounting, costing and
cardiovascular disease risk reversal (dominant
cost-effectiveness ratios). Dietary advice targeting
individuals is not cost-effective under any of the
modelled scenarios, even if directed at those with
highest blood pressure risk only (best case median costeffectiveness
A$100 000/DALY; 95% uncertainty interval
A$64 000/DALY to A$180 000/DALY). Although the
current programme that relies on voluntary action by the
food industry is cost-effective, the population health
benefits could be 20 times greater with government
legislation on moderate salt limits in processed foods.
Conclusions Programmes to encourage the food
industry to reduce salt in processed foods are highly
recommended for improving population health and
reducing health sector spending in the long term, but
regulatory action from government may be needed to
achieve the potential of significant improvements in
population health.
