Objective To explore the application of organism weak magnetic field technology in assessing the exposure of recurrent spontaneous abortion patients to environmental hazard factors, and provide reference for developing targeted preventive measures.
Method Morning urine samples were collected from 828 female patients suffered from recurrent spontaneous abortion (RSA) to determine 12 environmental exposure indexes (chemical factors, physical factors and biological factors) and 2 exposure effect indexes (liver endocrine and kidney endocrine) by organism weak magnetic field technology in the Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from March 2012 to February 2015.
Results The exposure effect indexes of liver endocrine and kidney endocrine were prominent in all tested patients, and the abnormal rates were 76.57% and 75.36%, respectively. The abnormal rate of three environmental exposure factors were chemical factors (66.30%) > biological factors (43.72%) > physical factors (14.13%). The abnormal rate related to foodborne factors in different BMI groups was higher in the thin group than that in the normal weight group. The abnormal rate for organic compounds was higher in the normal weight group than that in the overweight group. But the difference of all indexes among five age groups were insignificant (P>0.05).
Conclusions In general, the exposure to environmental factors, especially chemical factors, might increase the occurrence of RSA. Attention should be paid to enhancing protection, reducing exposure and avoiding damage in the environment of our daily life. The exposure of RSA patients to environmental factors could be evaluated relatively and quantitatively by organism weak magnetic field technology to provide references for the further study of developing targeted intervention.
