A catalog of recommended standard measures of phenotypes and environmental exposures for use in biomedical research. This includes common data elements for tobacco regulatory research, substance abuse and addiction, mental health research, sickle cell disease research, and social determinants of health.
Science Analysis System (SAS) code is available for analyzing Actigraph 7164 Physical Activity Monitor (PAM) data from the 2003–2004 National Health and Nutrition Examination Survey (NHANES). These programs are written to import and analyze accelerometer data downloaded from the National Center for Health Statistics (NCHS). Those who wish to use these programs with data downloaded directly from Actigraph 7164 accelerometers used in a different study must first convert the data into the appropriate format and merge the records from multiple accelerometers.
Information and resources for measuring long-term average daily intake, or "usual intake, including an NCI-developed method for estimating usual dietary intakes of foods and nutrients using 24-hour recalls. This method can be used to:
- Estimate the distribution of usual intake for a population or subpopulation
- Assess the effects of individual covariates on consumption
- Predict individual intake for use in a model to assess the relationship between diet and disease or other variable using the statistical technique of regression calibration.
