The study was conducted by the Research Triangle Institute (RTI) and the Environmental and Occupational Health Sciences Institute (EOHSI). myoclonic epilepsy: A systematic review and individual participant data meta-analysis. The Region 5 study was conducted in EPA's Region 5 (Ohio, Michigan, Illinois, Indiana, Wisconsin, and Minnesota), and included personal exposure, residential concentration, and biomarker measurements of metals and VOCs. Explore the latest high-quality research from The Lancet Group. The NHEXAS Phase I Questionnaires were organized into six modules for simplicity in administration (to minimize respondent burden and maximize participation rates at each step) and for collecting information that can be temporally related to the exposure, concentration and/or biological measurements collected in NHEXAS: Descriptive, Baseline, Technician, Follow-up, Time and activity diary, and Dietary diary (and follow-up). Phase I consists of demonstration/scoping studies using probability-based sampling designs. The National Human Exposure Assessment Survey (NHEXAS) is a federal interagency research effort coordinated by the Environmental Protection Agency (EPA), Office of Research and Development (ORD). The Region 5 study did not include activities about pesticides (this was the subject of a special study conducted only in Minnesota). The file contains all of the corresponding survey data.

NHEXAS Phase I studies used an OMB-approved questionnaire and could select the questions to be used to fit particular studies. The 2017 Workplace Health in America survey contains 2,843 records. It has two distinct portions: (1) the time diary, which identifies the times that a respondent spent in each of seven microenvironments during the monitoring period and (2) the activity diary, which identifies the respondent's level of participation in about 26 exposure-related activities. surveys are useful, what type of time-use data is available, what data. The Time Diary and Activity Questionnaire was used for collecting data on detailed (daily) time and location information and activity patterns (for relatively frequent activities when recalling events over several days would be more difficult for the participant). In gender statistics, time use surveys represent a useful source of information. Some participants were studied for more than one monitoring period. This data set includes responses for 249 participants with a total of 428 time-activity diaries.
