Abstract
Background an d Aim : Several factors can affect the sexual function of women. The aim of this study was to determine the correlation between exercise and sexual function in post-menopausal women.
Materials and Methods : This was a community-based, descriptive-analytical study including 405 post-menopausal women 40-65 years old selected by multi-stage stratified random sampling . The data were obtained through interviews using the Female Sexual Function Index (FSFI) and a researcher-made questionnaire. The data were analyzed using descriptive and analytical tests such as multiple linear regression and logistic regression models .
Results : On the whole, 61% of the subjects had sexual dysfunction. The most common type of exercise was “walking” (79.8%). For the women who exercised, the mean score in the domain of pain was significantly lower (worse) (p=0.013). The total FSFI, lubrication and pain domains scores were significantly lower in the women who did exercises other than walking as compared to those who did not exercise or practiced only walking. The weekly exercise frequency had positive correlations with lubrication (r=0.18, p=0.014) and orgasm (r=0.146, p=0.045) domain scores. However, multiple regression analysis to determine predictors of total score of FSFI and the domains scores did not give any statistically significant results. Finally, the logistic regression test showed that one additional exercise session per week would result in reduction of chances of sexual dysfunction by 80.2%.
Conclusion : Based on the findings, it may be concluded that exercise can be a w ay to compensate for sexual problems and dissatisfactions caused by reduced sex and sexuality in post-menopausal women. Exercising more frequently during the week could have positive effects on the sexual function of post-menopausal women.

Abstract
Background and Aim: Heavy metals in the surface soils of cities from various sources (traffic, industrial emissions, erosion from buildings, etc.) can accumulate through inhalation, ingestion and dermal contact in the human body and imperil health. The purpose of this study was to assess the ecological and human health risks caused by some heavy metals in roadside soil at the intersections of Ahvaz (Modares, Kharchar, Zargan, Behbahani, Golestan, Abadan, Khorramshahr, Susangerd and Andimeshk).
Materials and Methods: In this study, the concentration of heavy metals in roadside surface soils in intersections of Ahvaz in the summer of 2016 was investigated. The sampling at each intersection was carried out at specified intervals of 1, 10 and 30 meters on the sides of the main road (6 samples from each intersection) from the surface soil (depth 0 to 20 cm); the total number of samples was 54. The samples were transferred to the laboratory and dried at 60 ° C in an oven. After digestion of the samples with an acid mixture, concentrations of heavy metals Zn, Pb, Ni, Cu, Cr, Cd and As were measured by inductive coupled plasma-mass spectrometry (ICP-MS). The contamination level was estimated based on potential ecological and human health risks of heavy metals.
Results: The average concentrations of Zn, Pb, Ni, Cu, Cr, Cd and As were 116.61 ± 49.42, 284.02 ± 166.91, 25.53 ± 4.47, 220.63 ± 87.75, 137.21 ± 84.80, 3.44 ± 3.23 and 8.65 ± 3.8 mg/kg, respectively. Isotope ratios indicated that emissions from automobiles/traffic and industrial emissions were the most important sources of lead in the samples studied. The average value of potential ecological risk (RI) in Andimeshk, Golestan and Susangerd intersections was low; that in Modarres, Behbahani and Zergan intersections was medium; and that in Chaharsir, Abadan and Khorramshahr intersections was high. Cr poses the highest risk of cancer in both children and adults, although the risk of carcinogenesis in children is higher than in adults.
Conclusion: The results show that the source of contamination with the metals studied is anthropogenic, including road traffic and industrial activities, in the area investigated.
