Improved Measures of Diet and Physical Activity Program Genes, Environment, and Health Initiative (GEI)

The Genes, Environment, and Health Initiative (GEI) of the National Institutes of Health (NIH) was a four-year, NIH-wide initiative with projects led by several institutes. The overarching goal of the GEI was to determine the etiology of common diseases by focusing on the interaction of genetic and environmental factors to better understand how these interactions contribute to health and disease.

The GEI was an investment in genetic studies and environmental monitoring technologies. The genetic component was focused on genome-wide association studies and data analytic methods. The exposure biology component was focused on stimulating the development of innovative wearable sensors to measure environmental exposures such as toxins and toxicants, diet, physical activity, psychosocial stress, and addictive substances that contribute to the development of disease.

One program within the exposure biology component focused on improved measures of diet and physical activity. This program funded 7 studies to apply technological advances in other fields to the assessment of diet and physical activity to develop devices or methods which are reliable and valid, have low respondent burden, and are economically feasible for use in studies of free-living, diverse populations. The program was led by the National Heart, Lung and Blood Institute (NHLBI) and National Cancer Institute (NCI) from August 2007 to August 2011
