Developing Interview Questions to Estimate Workplace Exposure to Electric and Magnetic Fields

2014-08-27 03:44:00 | BioPortfolio

Summary

RATIONALE: Electric and magnetic fields may increase the risk of cancer. Developing interview questions that accurately estimate a person's exposure to electric and magnetic fields may help doctors learn about the long-term effects of workplace exposure.

PURPOSE: This clinical trial is developing interview questions that can be used in estimating workplace exposure to electric and magnetic fields.

Description

OBJECTIVES:

- Validate an interview-based electric and magnetic field exposure (EMF) assessment algorithm against measurements of the time-weighted average magnetic field magnitude used in previous epidemiologic studies.

- Calibrate the parameters in the algorithm in order to improve the exposure estimates.

- Correlate EMF exposure estimates from the algorithm with biologically based metrics measured by new instrumentation.

OUTLINE: Participants respond to questions during a 5- to 15-minute telephone interview concerning workplace exposure to electric and magnetic (EMF) fields. Data is collected during the interview using an exposure assessment algorithm designed to estimate EMF workplace exposure based on participants' responses. The interview-based estimates are then validated against actual field measurements of magnetic field exposure captured by Emdex multiwave monitors located at participating sites.

Medical and Biotech [MESH] Definitions

Administration of a medication to at-risk individuals in a population without individual diagnosis. It is often used in order to treat, control, and/or prevent spread of often endemic DISEASE OUTBREAKS such as NEGLECTED DISEASES in high disease burden areas.

Factors that can cause or prevent the outcome of interest, are not intermediate variables, and are not associated with the factor(s) under investigation. They give rise to situations in which the effects of two processes are not separated, or the contribution of causal factors cannot be separated, or the measure of the effect of exposure or risk is distorted because of its association with other factors influencing the outcome of the study.

The relating of causes to the effects they produce. Causes are termed necessary when they must always precede an effect and sufficient when they initiate or produce an effect. Any of several factors may be associated with the potential disease causation or outcome, including predisposing factors, enabling factors, precipitating factors, reinforcing factors, and risk factors.
