Age standardized incidence rates of breast cancer in developed countries is nearly threefold higher than in developing countries. Iran has had one of the lowest incidence rates for breast cancer in the world, but during the last four decades increasing incidence rates of breast cancer made it the most prevalent cancer in Iranian women. After adjustment for age, Iranian young women are at relatively higher risk of breast cancer than their counterparts in developed countries. The purpose of this study was to investigate some established risk factors of breast cancer in Iranian young women. A hospitalbased case control study comprising 521 women with histologically confirmed, incident breast cancer and 521 controls frequency-matched by age and province of residence was conducted. Logistic regression performed to investigate associations of reproductive and anthropometric factors with breast cancer risk. In multivariate analysis, family history [odds ratio (OR): 1.61; 95% confidence interval (CI): 1.07-2.42], oral contraceptives (OC) usage (OR: 1.52; 95% CI: 1.11-2.08), low parity (OR parity ! 3 vs. 1-2: 0.33; 95% CI: 0.23-0.49), employment (OR: 1.83; 95% CI: 1.05-3.23) and shorter period of breast feeding (OR ! 37 months vs. < 37: 0.61; 95% CI: 0.44-0.84) were related to a higher risk of breast cancer in young women. This was the first study focusing on risk factors of breast cancer in Iranian young women. The trend of decreasing parity and shortened duration of breast feeding along with OC usage might partly explain the rapid rising of breast cancer incidence in Iranian young women.Breast cancer is the second most prevalent cancer in the world and the most common cancer among women. Breast cancer still persists as an international health burden despite advances in its early diagnosis, treatment and also increased knowledge of its established risk factors.

Iron deficiency anemia is the most prevalent micronutrient deficiency in the world, affecting 20-50% of the world's population. It is estimated that 10 and 20% of male and female athletes are iron deficient, respectively. Iron deficiency has deleterious effects on the physical performance of athletes. It decreases aerobic capacity, increases heart rate and elongates the recovery time after exercise. In this cross-sectional study, 42 semi-professional female athletes who had been playing in basketball, volleyball and handball super league teams served as subjects. Data on socioeconomic and fertility status as well as the type of sport were obtained through a questionnaire. Nutritional data were gathered with a 3 day dietary recall. Total intake of calorie, iron, zinc, folate, vitamin C and B12 were also analyzed. In addition, ferritin and TIBC were measured and a CBC test was done for each subject. The results showed that the mean total calorie intake of women was 2049.79 +/- 735.12 kcal, where their iron intake was 22.33 +/- 9.24 mg day(-1). There was a significant difference between the iron intake of basketball and volleyball players (p = 0.036). Of our subjects, 33.33% had low ferritin levels (< 30 ng mL(-1)) and it was lowest in handball players. Higher than normal ferritin levels were seen in 12.5% of the subjects. We saw a significant difference in ferritin levels of basketball and handball players (p = 0.047). We conclude that the intake of calorie and iron is low in female athletes and therefore, their hematological indices such as ferritin level are below standard values.

Background: The current study aimed to measure and decompose socioeconomic-related inequalities in DMFT (decayed, missing, and filled teeth) index among adults in Iran. Methods: The study data were extracted from the adult component of Prospective Epidemiological Research Studies in IrAN (PERSIAN) from 17 centers in 14 different provinces of Iran. DMFT score was used as a measure of dental caries among adults in Iran. The concentration curve and relative concentration index (RC) was used to quantify and decompose socioeconomic-related inequalities in DMFT. Results: A total of 128,813 adults aged 35 and older were included in the study. The mean (Standard Deviation [SD]) score of D, M, F and DMFT of the adults was 3.3 (4.6), 12.6 (10.5), 2.1 (3.4) and 18.0 (9.5), respectively. The findings suggested that DMFT was mainly concentrated among the socioeconomically disadvantaged adults (RC = − 0.064; 95% confidence interval [CI), − 0.066 to − 0.063). Socioeconomic status, being male, older age and being a widow or divorced were identified as the main factors contributing to the concentration of DMFT among the worse-off adults. Conclusions: It is recommended to focus on the dental caries status of socioeconomically disadvantaged groups in order to reduce socioeconomic-related inequality in oral health among Iranian adults. Reducing socioeconomicrelated inequalities in dental caries should be accompanied by appropriate health promotion policies that focus actions on the fundamental socioeconomic causes of dental disease.

Background:Coronary artery diseases are the most frequent cause of mortality in industrialized countries as well as Iran. Coronary artery disease affects patient’s quality of life (QoL) and produces some degrees of anxiety and depression. Although self-management programs have shown significant impact on chronic diseases, there is limited evidence in Iran regarding the effectiveness of these interventions, particularly in patients with coronary artery disease.Objectives:This study aimed to evaluate the effects of angina plan on QoL, anxiety, and depression in post coronary angioplasty patients referred to selected hospitals in Shiraz.Patients and Methods:This parallel randomized, controlled trial was conducted in selected hospitals in Shiraz, Iran. We enrolled 80 post coronary angioplasty eligible patients in the study. After acquisition of the informed consent, eligible patients were randomly divided into two groups: control and experimental. Pretest data were obtained by using a demographic data form and two valid and reliable questionnaires for QoL, anxiety, and depression. Blood pressure, weight, and height (to calculate body mass index) were measured too. Patient’s history of smoking, diabetes, hypercholesterolemia, hypertension, and coronary vascular involvement (with grade and severity) were obtained from their medical records. A 12-week angina plan intervention consisted of a 30 to 40 minutes of counseling interview and telephone follow up at the end of 1, 4, 8, and 12 weeks were performed for experimental group. Post-test data were obtained three months after the pretest using the same questionnaires as pretest. QoL data were analyzed by analysis of co-variance (ANCOVA). The results (before and after intervention) regarding anxiety and depression were analyzed by independent t-tests or their equivalent nonparametric Mann-Whitney test using SPSS v. 11.5.Results:There was no statistically significant difference in demographic variables between two groups. Baseline mean scores for QoL, anxiety, and depression did not differ between the two groups. There was a significant difference between the experimental and control groups in terms of changes in perception of QoL before and after the intervention. Adjusted mean ± SD of perception of QoL for the control group was 38.48 ± 13.38 and for the experimental one was 56.30 ± 13.38, with a P value of less than 0.001. The mean difference of anxiety scores (before and after intervention) in experimental and control groups were 1.15 ± 1.99 and­.0.07 ± 2.22, respectively with a P value of less than 0.01. The mean difference of depression scores (before and after intervention) in experimental and control groups were 0.4 ± 2.89 and 0.13 ± 2.76, respectively (P > 0.05).Conclusions:Our results show that the self-management angina plan was effective in improving perception of QoL and reducing anxiety. Further studies with a larger sample size and a longer follow-up period are recommended to better understand the effectiveness of this plan.

Background:Despite the advances in the diagnosis and treatment of leishmaniasis, it is still considered as a severe public health problem particularly in developing countries and a great economic burden on the health resources. The present study was designed and conducted to determine the eco-environmental characteristics of the leishmaniasis disease by spatial analysis.Materials and Methods:In an ecological study, data were collected on eco-environmental factors of Fars province in Iran and on cutaneous leishmaniasis (CL) cases from 2002 to 2009. geographic weighted regression (GWR) was used to analyse the data and compare them with ordinary least square (OLS) regression model results. Moran's Index was applied for analysis of spatial autocorrelation in residual of OLS. P value less than 0.05 was considered as significant and adjusted R2 was used for model preferences.Results:There was a significant spatial autocorrelation in the residuals of OLS model (Z=2.45, P=0.014). GWR showed that rainy days, minimum temperature, wind velocity, maximum relative humidity and population density were the most important eco-environmental risk factors and explained 0.388 of the associated factors of CL.Conclusion:Spatial analysis can be a good tool for detection and prediction of CL disease. In autocorrelated and non-stationary data, GWR model yields a better fitness than OLS regression model. Also, population density can be used as a surrogate variable of acquired immunity and increase the adjusted R2.
