Excess intake of sodium, a common problem worldwide, is associated with hypertension and cardiovascular disease (CVD), and hypertension is a major risk factor for CVD. Population-wide efforts to reduce sodium intake have been identified as a promising strategy for preventing hypertension and CVD, and such initiatives are currently recommended by a variety of scientific and public health organizations. By reviewing the literature published from January 2011 to March 2013, we summarized recent economic analyses of interventions to reduce sodium intake. The evidence, derived from estimates of resultant blood pressure decreases and thus decreases in the incidence of CVD events, supports population-wide interventions for reducing sodium intake. Both lowering the salt content in manufactured foods and conducting mass media campaigns at the national level are estimated to be cost-effective in preventing CVD. Although better data on the cost of interventions are needed for rigorous economic evaluations, population-wide sodium intake reduction can be a promising approach for containing the growing health and economic burden associated with hypertension and its sequelae.

Although population-wide efforts to reduce sodium intake are promising for preventing hypertension and CVD, this study warned that robust evidence does not support universal reduction of sodium intake. For individuals whose diet falls outside the “safe” range of sodium intake, there is no evidence that reducing sodium intake will lead to better health outcomes..

Estimating the potential health impact and costs of implementing a local policy for food procurement to reduce the consumption of sodium in the county of Los Angeles. Am J Public Health. 2011;101:1501–7. Although this study only focused on a local policy at a county level, the approaches in estimating the health impact as well as the costs of implementation can be applied to other settings. It provided an empirical framework of policy evaluation by estimating both the health impact and the cost of implementation. This is a good step toward developing practical intervention programs..

This study emphasized that cost-effectiveness modeling clearly has a valuable role in policy-making. The results of the economic evaluation can be used to prioritize public health interventions such as population-wide salt intake reduction. Furthermore, the authors offered a number of lessons learned in translating epidemiologic and other scientific findings into policy..
