BOX 1 COMMITTEE'S STATEMENT OF TASK An ad hoc committee under the auspices of the Institute of 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.

... Kauh concluded by stressing the importance of the committee weighing methodological rigor against what can be realistically implemented in a public health setting. DATA ANALYSIS AND INTERPRETATION The first session of the workshop explored methodological considerations for studies of obesity prevalence and trends, using two federal data sources as examples: the National Health and Nutrition Examination Survey (NHANES)

... For children birth to age 4 years, growth standards were developed using data from the Multicentre Growth Reference Study, which had data collection sites in Brazil, Ghana, India, Norway, Oman, and the United States. Rather than being nationally representative, data were collected from children with optimal nutrition, environment, and care.

... Similar to Ogden, Kann demonstrated that changing the starting point for assessing trends can lead to different results and interpretations, with an increase in obesity prevalence emerging between 1999 and 2013, but estimates remaining fairly consistent over the past four to five cycles of data collection. When asked to describe the biggest challenge facing the YRBSS, Kann stated, "school-based surveys are unique in the sense that there are a whole lot of gatekeepers … we are so far away from our actual respondent." FRAMEWORK DEVELOPMENT AND IMPLEMENTATION The second session explored the development and implementation of effective frameworks from two different perspectives -- education and public health.

... PANEL DISCUSSION The third session of the workshop provided insight into the approaches to and challenges of assessing obesity prevalence and trends at the local and state levels. The four panelists were Lisa Pivec of the Cherokee Nation Health Services, Thomas Ricketts of the University of North Carolina at Chapel Hill, Paul Simon of the Los Angeles County Department of Public Health, and Joseph Thompson of the Arkansas Center for Health Improvement.

... Next, Charles Bailey of Children's Healthcare of Philadelphia described ways electronic health records (EHRs) are being used to assess pediatric obesity within PEDSnet, which is "a collaboration of eight large pediatric health systems in the United States, built around learning health system principles." He explained that the number of height and weight measurements recorded in children's EHRs is often bolstered because pediatricians monitor growth, medications are typically dosed on weight, and schools often require a well-child check.

... Summarizing the findings, Bailey noted that these data were very reliable and consistent and yielded relatively similar results to resource-intensive national survey data. He also presented findings using longitudinal EHR data to examine associations between select exposures and subsequent obesity.
