Using Population Reach as a Proxy Metric for Intervention Impact to Prioritize Selection of Obesity Prevention Strategies in Los Angeles County, 2010–2012.

Recent federal initiatives have used estimates of population reach as a proxymetric for intervention impact, in part to inform resource allocation and programmatic decisions about competing priorities in the community. However, in spite of its utility, population reach as a singular metric of intervention impact may be insufficient for guiding multifaceted program decisions. A more comprehensive, validated approach to measure or forecast dose may complement reach estimates to inform decision makers about optimal ways to use limited resources. [ABSTRACT FROM AUTHOR]
