Epidemiological and laboratory studies of power frequency electric and magnetic fields

Article Abstract:

Exposure to electric and magnetic fields (EMF) may be harmful to an individual's health. Electrical conductors such as appliances, household wiring and power wires are surrounded by a combination of EMF. The strength of these fields decreases as the distance from the electrical conductor increases. Exposure to EMF can cause sensations such as slight tingling of the hair and microshocks, from the low frequency electricity. In the 1960s, medical researchers in the USSR discovered that EMF may be detrimental to human health. Several studies found that children and adults with high exposure to EMF had an increased risk of developing cancer, compared with the general population. Exposure to EMF may also cause miscarriages and birth defects. Children whose fathers have been exposed to EMF may have an increased risk of developing brain cancer. Some scientists believe that increased exposure to EMF may cause psychological disorders.

How Do Observational Studies Expand the Evidence Base for Therapy?

Article Abstract:

Observational studies can provide doctors with data about people who would not necessarily participate in a randomized clinical trial of a particular treatment but who may still need the treatment. Doctors can apply a technique called propensity analysis to observational studies to eliminate some of the problems posed by observational studies.
