Background: In Iran, 82% of breast cancer cases are diagnosed in late stages, resulting in low survival rates. In the present study, the Stages of Change Theory and Health Belief Model were used as theoretical frameworks for assessing Women Health Volunteer readiness to act on different breast cancer screening behaviors. Methods: A total of 1,410 Women Health Volunteers were enrolled in this cross-sectional study. The breast self-examination (BSE) and mammography stages of change were measured independently. A standardized questionnaire based on the Health Belief Model was used to assess their beliefs about breast cancer screening methods. A path analysis using PASW SPSS ver. 18.0 (SPSS Inc., Chicago, IL, USA) was used to test the effects of individual beliefs on breast cancer screening stages of change. Results: Most participants were classified in the pre-contemplation stage of breast cancer screening behaviors. Perceived barriers, benefits, and susceptibility emerged as BSE stages of change predictors. No beliefs were significant mammography stages of change predictors. Conclusion Iranian Women Health Volunteers had a very low adherence to common BSE and mammography practices. Healthy beliefs have a strong association with the stages of change for performing BSE, but not for mammography. The impact of health beliefs on an individual’s readiness to act on different breast cancer screening methods may vary with respect to the type of screening method.

PURPOSE: Polycystic ovary syndrome (PCOS) is a gynecological endocrine disorder that is characterized by disturbances in ovarian blood flow and angiogenesis. The aim of this study was to determine the association of vascular endothelial growth factor (VEGF) and thrombospondin-1 (TSP-1) serum levels with the body mass index (BMI) in patients with PCOS compared with healthy subjects. METHODS: The study was conducted with 80 subjects in 3 PCOS groups, including normal weight, overweight, and obese PCOS groups, and a control group of healthy subjects (n=20). The participants in all groups completed a questionnaire comprising sociodemographic and obstetric questions. The PCOS diagnosis in the study subjects was confirmed based on the Rotterdam criteria, BMI was determined according to the World Health Organization guidelines, and the lipid accumulation product index was calculated for all groups. Venous blood samples were collected from all participants after fasting to measure the serum levels of fasting blood glucose (FBG), lipids, insulin, VEGF, TSP-1, and leptin. RESULTS: Our findings showed that the serum VEGF level was significantly higher in the normal BMI PCOS group than that in the control group (P=0.03), and the TSP-1 level was significantly lower in the obese PCOS group than that in the control group (P=0.04). CONCLUSIONS: Our study demonstrated that alterations in VEGF and TSP-1 concentrations are dependent on BMI. Because abnormal ovarian angiogenesis is considered to be the main feature of PCOS, the study of ovarian angiogenic imbalance is proposed as a new tool for PCOS diagnosis and management.
