We examined approaches to reduce sodium content of food served in settings operated or funded by the government of the County of Los Angeles, California.
We adapted health impact assessment methods to mathematically simulate various levels of reduction in the sodium content of food served by the County of Los Angeles and to estimate the reductions' potential impacts on mean systolic blood pressure (SBP) among food-service customers. We used data provided by county government food-service vendors to generate these simulations.
Our analysis predicted that if the postulated sodium-reduction strategies were implemented, adults would consume, on average, 233 fewer milligrams of sodium each day. This would correspond to an average decrease of 0.71 millimeters of mercury in SBP among adult hypertensives, 388 fewer cases of uncontrolled hypertension in the study population, and an annual decrease of $629,724 in direct health care costs.
Our findings suggest that a food-procurement policy can contribute to positive health and economic effects at the local level. Our approach may serve as an example of sodium-reduction analysis for other jurisdictions to follow.
我们研究了减少加利福尼亚州洛杉矶县政府运营或资助的场所供应食物中钠含量的方法。
我们采用健康影响评估方法，对洛杉矶县政府供应食物中的钠含量进行不同程度的降低，并估计这些降低对食品服务客户平均收缩压（SBP）的潜在影响。我们使用县政府食品服务供应商提供的数据来生成这些模拟。
我们的分析预测，如果实施假设的减钠策略，成年人每天将平均减少 233 毫克钠。这将对应于高血压成年人 SBP 平均降低 0.71 毫米汞柱，研究人群中未经控制的高血压病例减少 388 例，以及每年直接医疗保健费用减少 629,724 美元。
我们的研究结果表明，食品采购政策可以在地方层面带来积极的健康和经济效益。我们的方法可以为其他司法管辖区提供减钠分析的范例。
