Background: Health-related quality of life is affected by electromagnetic field exposure in each person everyday life. However, this is extremely controversial issue. Objective: Investigation of the associations between electromagnetic field exposure and miscarriage among women of Tehran. Materials and Methods: In this longitudinal study, 462 pregnant women with gestational age <12 wks from seven main regions of Tehran city in Iran with similar social and cultural status were participated. Women were interviewed face-to face to collect data. Reproductive information was collected using medical file recorded in those hospitals the subjects had delivery. The measuring device measured electromagnetic waves, Narda safety test solutions with valid calibration date at the entrance door of their houses. Results: A significant likelihood of miscarriage in women who exposed to significant level of electromagnetic wave. However, this association was not confirmed by Wald test. Conclusion: This study may not provide strong or consistent evidence that electromagnetic field exposure is associated or cause miscarriage. This issue may be due to small sample size in this study.

Background: Intimate partner violence (IPV) and risky sexual behaviors are serious and overlapping public health problems that disproportionately affect drug-involved women. Despite the fact that drug-using women experience extensive IPV, to date, no studies have investigated the association of IPV and risky sexual behaviors among drug-using women in Iran. Methods: Drug-using women (N =120) were recruited from a rehabilitation center in Tehran from March to October, 2009. The Revised Conflict Tactics Scale (CTS2), a standardized questionnaire, was used to collect data regarding violence. We used t-test and logistic regression models to explore the relationship between IPV domains and specific sexual risk behavior outcomes using SPSS 21. Results: The means (sd) for CTS2 domains were as follows: negotiation 4.29 (1.55), psychological violence 2.55 (1.51), sexual violence 0.37 (1.00), physical abuse 1.17 (1.49), injury 2.18 (1.97), and the mean total score was 1.69 (0.96). We found significantly higher injury scores, but lower sexual abuse scores among women with sexually-transmitted infection (STI) compared to women without STI (p-values 0.030 and <0.0001, respectively). In addition, we found that psychological abuse was positively associated with STI (p-value 0.03) and increased condom use (p = 0.010), possibly mediated through an increased likelihood of having multiple partners. Conclusion: The findings revealed that in Iran drug-involved women experience high rates of IPV and that IPV is associated with increased risky sexual behavior. Implication: Preventive interventions for violence that are integrated within drug treatment programs, as well as harm reduction programs are highly recommended. [ABSTRACT FROM AUTHOR]
