C-36 Free Communication/Poster - Measurement of Physical Activity and Sedentary Behavior Thursday, May 31, 2018, 7: 30 AM - 12: 30 PM Room: CC-Hall B
There are many types of physical activity and food intake measures. These measures often lack validity and reliability, making it difficult to compare findings across childhood obesity research and evaluation studies.
PURPOSE: The National Collaborative on Childhood Obesity Research’s (NCCOR) Measures Registry (nccor.org/mruserguides) promotes consistent use of high-quality, comparable measures and methods across childhood obesity studies. The Registry User Guides extend the reach and usefulness of these resources. Herein we describe the Registry and User Guides and examine their reach to nutrition, physical activity, and obesity researchers and practitioners.
METHODS: A search of peer reviewed literature published 1999-2009 was conducted. Measurement experts reviewed and abstracted articles meeting inclusion criteria in four domains: physical activity, diet, physical activity environment, and food environment. The Registry was launched in 2011 and has been updated on an ongoing basis since August 2015. In 2017, subject matter experts authored four User Guides for the measurement domains. The Guides include case studies to help users’ select appropriate measures. The number of web visitors to the Registry and Guides was tracked providing an indicator of reach.
RESULTS: The Registry contains 1207 published studies of validation research using measures of physical activity (n=403), diet (n=330), physical activity environment (n=273), and food environment (n=331). Measures include GIS (n=127); 24-hour dietary recall (n=52); food frequency (n=69); electronic monitor (n=121); environmental observation (n=153); questionnaire (n=498); record or log (n=97), and other (n=207). Over 17,100 unique visitors have accessed the Registry since its launch, including visitors from 41 countries. Since their release there have been over 8000 page views of the User Guides from 3633 unique visitors.
CONCLUSION: The NCCOR Measures Registry and User Guides can assist researchers and practitioners conducting childhood obesity prevention research and evaluation to select high quality, comparable measures of physical activity, diet, and the environments in which these behaviors occur. Website traffic reflecting access to the materials indicates a large reach.
