View Original AbstractThere was a significant difference between case and control groups in sleep quality and general health, but no significant relationship was found between exposure level and these outcomes.
Plain English Summary
Researchers measured magnetic flux density in a control building and two substations according to IEEE standard 644-1994. They used the Pittsburgh Sleep Quality Index and General Health Quality questionnaires to assess sleep quality and public health in 40 workers. In the case group, 28% had poor health status and 61% had a sleep disorder, while all control group members were in good health and only 4.5% had undesirable sleep quality. A significant difference existed between groups in sleep quality and general health, but no significant relationship was found between exposure level and these outcomes. Measured EMF values were below ACGIH limits, and the authors recommended further epidemiological studies and periodic testing.
Why This Matters
The study aimed to determine a possible correlation between ELF EMFs and sleep quality and public health of workers in substation units of a petrochemical complex in southern Iran. The questionnaires were analyzed using T-test, Duncan, and Chi-square tests.
Study Details
This study was performed to determine possible correlation between Extremely Low Frequency Electro-Magnetic Fields (ELF EMFs) and sleep quality and public health of those working in substation units of a petrochemical complex in southern Iran.
To begin with, magnetic flux density was measured at different parts of a Control Building and two s...
The obtained results revealed that 28% of those in case group suffered from poor health status and 6...
In spite of a significant difference between the case and control groups in terms of sleep quality and general health, no significant relationship was found between the exposure level and sleep quality and general health. It is worth noting that the measured EMF values were lower than the standard limits recommended by American Conference of Industrial Hygienists (ACGIH). However, given the uncertainties about the pathogenic effects caused by exposure to ELF EMFs, further epidemiological studies and periodic testing of personnel working in high voltage substations are of utmost importance.
