Current performance on the transition core outcome leaves much room for improvement. Many parents feel that having transition-related discussions with their health care providers would be helpful. Future clinical and policy-level research should be directed at identifying barriers to, and recommending content for, health transition discussions.

Text4baby is the first free national health text messaging service in the United States that aims to provide timely information to pregnant women and new mothers to help them improve their health and the health of their babies. Here we describe the development of the text messages and the large public-private partnership that led to the national launch of the service in 2010. Promotion at the local, state, and national levels produced rapid uptake across the United States. More than 320,000 people enrolled with text4baby between February 2010 and March 2012. Further evaluations of the effectiveness of the service are ongoing; however, important lessons can be learned from its development and uptake.

Population-level interventions focused on policy, systems, and environmental change strategies are increasingly being used to affect and improve the health of populations. At the same time, emphasis on implementing evidence-based public health practices and programming is increasing, particularly at the federal level. Valuing strategies in the population health domain without the benefit of demonstrated efficacy through highly rigorous methods introduces an inherent tension between planning and acting on the best evidence available, waiting for more rigorous evidence to emerge, as well as exploring innovative ways to evaluate and model evidence-based strategies. This article describes the creation of a resource that helps public health practitioners use current evidence for strategic decision making while building the evidence base for population-level interventions. The resource addresses topics of current discussion in the field of evaluating population-level interventions, including the tension between internal and external validity, the need to include measures of health equity, and the balance between fidelity to the intervention and adaptation to the community context. The resource is intended to advance development of evidence in the field by providing practitioners, project managers, and evaluators with a practical guide for using, reviewing, and adding to the existing evidence base.

IntroductionIn 2010, the Centers for Disease Control and Prevention funded 50 communities to participate in the Communities Putting Prevention to Work (CPPW) program. CPPW supported community-based approaches to prevent or delay chronic disease and promote wellness by reducing tobacco use and obesity. We collected the direct costs of CPPW for the 44 communities funded through the American Recovery and Reinvestment Act (ARRA) and analyzed costs per person reached for all CPPW interventions and by intervention category.MethodsFrom 2011 through 2013, we collected quarterly data on costs from the 44 CPPW ARRA-funded communities. We estimated CPPW program costs as spending on labor; consultants; materials, travel, and services; overhead activities; and partners plus the value of in-kind donations. We estimated communities’ costs per person reached for each intervention implemented and compared cost allocations across communities that focused on reducing tobacco use, or obesity, or both. Analyses were conducted in 2014; costs are reported in 2012 dollars.ResultsThe largest share of CPPW total costs of $363 million supported interventions in communities that focused on obesity ($228 million). Average costs per person reached were less than $5 for 84% of tobacco-related interventions, 88% of nutrition interventions, and 89% of physical activity interventions. Costs per person reached were highest for social support and services interventions, almost $3 for tobacco‑use interventions and $1 for obesity prevention interventions.ConclusionsCPPW cost estimates are useful for comparing intervention cost per person reached with health outcomes and for addressing how community health intervention costs vary by type of intervention and by community size.
