• To address its task, the committee considered a wide range of materials from the peer-reviewed literature, along with publicly available national, state, and local research and surveillance sources and held a public workshop. • This report includes an examination of current approaches to data collection and analysis, offers a conceptual framework for assessing and interpreting reports on obesity prevalence and trends, and provides recommendations for evaluating reports and improving future research initiatives.

Although far from exhaustive, these considerations must be factored into the study design, the data collection procedures, and the analytic approach. How investigators overcome methodological challenges ultimately informs the interpretation of estimates.

Ritzman and Elmore (2006) , for example, authored a statistical brief intended for health care professionals that described the weight status of middle and high school students from two cycles of the North Carolina Youth Risk Behavior Survey.

To be inclusive, the committee considered a wide range of materials from the peer-reviewed literature, BOX 1-2 Statement of Task An ad hoc committee under the auspices of the National Academies of Sci ences, Engineering, and Medicine will examine methodological approaches to data collection, analytic procedures, and interpretation of data at the national, state, and local levels on issues related to obesity status in U.S. populations, principally children, up to 18 years of age, with consideration for inclusion of indi viduals up to 21 years of age and measures of trends in obesity.

From these activities, the committee developed a framework for assessing and interpreting reports on obesity prevalence and trends and recommendations for evaluating published reports, and filling data gaps improving future data collection efforts. Scope This report delineates the current practices, challenges, and considerations related to data collection and analysis that ultimately affect the interpretation of estimates of obesity prevalence and trends across population groups, with a focus on children, adolescents, and young adults.

• Focus on Children, Adolescents, and Young Adults: Consistent with its charge, the committee primarily evaluated data collection and analysis methodologies in published reports that included pop ulation groups ages 18 years and younger. Brief discussions about how specific methodologies differ for the assessment of children and adults have been incorporated throughout the report, but are not a main focus.

Although recommendations for advancing the field are offered, the committee has not been charged with developing a prescriptive set of best practices for data collection, analysis, and reporting or identifying what resources would be required to implement changes. Furthermore, this report is not intended to provide an overview of the etiology of obesity, comprehensively evaluate its association with chronic disease, or provide guidance on effective initiatives, interventions, policies, or other solutions.

Published Reports Unless otherwise noted, the term "published report" describes a publication, peer-reviewed or otherwise, with original analysis that produces an estimate of obesity prevalence or trend. Some publications are summaries of primary analyses and may not contain details needed to adequately assess the findings.

. In addition to this previous work by the Academies, the committee was informed by stakeholder perspectives, peer-review reports on obesity prevalence and trends, and data collection protocol manuals.

Chapter 4 describes and compares a range of common data sources and identifies existing gaps. Chapter 5 discusses the various analytic approaches that have been used in recent reports and describes interpretive considerations associated with statistical analyses.
