Assessing Prevalence and Trends in Obesity

Navigating the Evidence

Estimates of prevalence and trend in obesity are used to inform a wide variety of decisions, including those related to policies, research, and interventions. The data sources from which such estimates are derived range from local initiatives to national surveillance programs, differing in terms of resources, intent, funding, and approach. Differences extend into the analyses, which are driven by the specific question(s) being asked, the quantity and quality of the data, and the analytic capabilities of the investigators. Inconsistencies exist across reports and have created barriers to interpreting and using such statistics.

To help policy makers, program planners, and other stakeholders overcome these challenges, the National Academies of Sciences, Engineering, and Medicine convened an expert committee to develop a framework that provides guidance on how to better assess and apply reports on obesity. This infographic serves as a guide to the Assessing Prevalence and Trends (APT) Framework.
