OBES-8: Review data available and apply to restricted use data

[sgiambra]

[Goal] There are many datasets that could be used in this research. Some of them have also a restricted use version. Examples are the Healthy School Program data and NHANES through NCHS. The goal of this task is to survey all relevant data. Next, I will apply and try to obtain access to the restricted use data.

[Steps]

• Describe all relevant data
• Understand which are the advantages of the restricted use data
• Understand the requirements
• Start the application process whenever possible

A good starting point for this task is this pdf written by Finkelstein, which surveys a large fraction of the existing datasets related to health 2016_health_data.pdf

A second extremely valuable catalogue is compiled by NCCOR and available here.

Some interesting sources of data:

• CDC county level data for adult obesity from 2004 to 2013.
• State of Obesity mentions other source such as NSCH 2016.
• NICH keeps fact sheets with obesity and other health related info at the county level. Unfortunately there is no data on childhood obesity.
• Similar to the above, USDA Food Environment Atlas.
• Youth Risk Behavior Surveillance System looks at children 9th through 12th grade from 1991 to 2015.
• Childhood Obesity Index creates a map at the county level based on NHANES.
• Interesting county level index on health outcomes constructed from multiple sources from the Robert Wood Johnson Foundation.

USDA databases on food content (can be linked to NHANES), most of them available here:

• Food and Nutrient Database for Dietary Studies: To translate typical portions of foods into gram weights and provide associated nutrient values. FNDDS was developed to analyze the nutrient content of diets reported in What We Eat in America (WWEIA), the dietary intake component of the National Health and Nutrition Examination Survey (NHANES).
• Food Patterns Equivalents Database: To convert foods and beverages in the U.S. Department of Agriculture’s (USDA) Food and Nutrient Database for Dietary Studies (FNDDS) to 37 USDA Food Patterns (FP) components.
• Food Intakes Converted to Retail Commodities Database: To convert foods consumed in national dietary intake surveys to commodities at the retail level in the United States (US).
• Center for Nutrition Policy and Promotion Food Prices Database: To collect data about estimated cost of specific food items consumed in the United States (US).
• National Nutrient Database for Standard Reference, Release 28: To provide authoritative food composition data for foods available in the United States (US). This national resource is the most authoritative source of food composition data in the US; virtually all other sources of food composition data are derived from this source.

National Longitudinal Study of Adolescent to Adult Health: Longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. Approximately 90,100 adolescents completed the in-school questionnaire in 1994-1995. School administrators completed questionnaires for 144 schools in 1994-1995.

Schools data:

• National Center for Educational Statistics Common Core of Data: To provide an official listing of public elementary and secondary schools and school districts in the United States (US). This system also collects descriptive and demographic data on these schools and school districts.
• Private School Universe Survey: To produce aggregate counts of private schools, students, and teachers, and to serve as a sampling frame for National Center for Education Statistics (NCES) sample surveys of private schools. This system also collects descriptive and demographic data on these schools, teachers, and students.
• School Health Profiles: To collect data about health practices and policies for middle and high schools in the United States (US) and its territories.
• Schools and Staffing Survey: To collect data about characteristics of schools and their staff in the United States (US).
• School Nutrition Dietary Assessment Study: To collect data about the nutritional quality of meals offered, served, and consumed in public schools that participate in the National School Lunch Program (NSLP) and the School Breakfast Program (SBP) in the United States (US). The study also collects data about district and school policies and key characteristics of program operations.
