The UAE-UNC Indoor Air, Health, and Nutrition Study, scheduled for full field implementation in Fall 2009, is a cross-sectional study of all seven emirates that examines indoor and outdoor air pollution exposures, chronic health conditions, respiratory symptoms, individual and household-level characteristics, health behaviors, obesity, and "nutrition transition" in 600 randomly sampled households of Emirati citizens in the United Arab Emirates (UAE). The study, sponsored by the Environment Agency-Abu Dhabi, is one of four components of the UAE National Strategy for Environment and Health, in which UAE and UNC researchers work collaboratively to develop a 10-year national plan to improve the environmental and health conditions at the UAE.
