    Prevalence of obesity has increased recently especially in women. Obesity is related to mortality due to non-communicable diseases and has become a public health issue. Among the two important factors to reduce weight calorie limitation alone is modestly effective in initial weight but can result in weight gain after primary weight reduction is common. Therefore adding physical activity to weight maintenance program can reduce weight gain rebound. The aim of this review article was to identify the preventive effect of physical activity on weight maintenance in overweight women. Articles were selected from PubMed database and screened for the relativity to the study objectives, using scoring systems. Eleven studies were found appropriate. No statistical test was done on the data except simple mean and some descriptive analyses. Physical activity is proved to have a significant effect in weight loss/maintenance both in induction and maintenance period. This effect was more significant in higher intensities. Sever intensity physical activity can be effective in weight maintenance in long term but the effect of moderate and light physical activity could not be evaluated due to lack of data.

    BACKGROUND: In order to provide a better healthcare education to the society, health care students should have an acceptable electronic health (E-Health) literacy.
    OBJECTIVE: The aim of this study was to assess the level of E-Health literacy of Medicine and Health Sciences university students in Mashhad, Iran.
    METHODS: This cross-sectional study was performed on 192 students of Mashhad University of Medical Sciences using a validated Persian translate of the E-Health literacy scale (P-EHEALS) questionnaire in 2016. Demographic data including age, monthly income, level of education, preference of website for obtaining health related information and minutes of Internet use per day were obtained from the subjects. Independent-samples t-test and analysis of variance (ANOVA) were used for comparison between groups, and Pearson correlation coefficient and linear regression were used to assess the correlation between study parameters and EHEALS score using SPSS version 21.
    RESULTS: A total of 192 (67.2% female and 32.8% male) subjects with mean age of 24.71±5.30 years participated in the study. Mean P-EHEALS score of the subjects was 28.21±6.95. There was a significant difference in P-EHEALS score between genders (p<0.001), department (p=0.001), education level (p<0.001) and health status (p=0.003) as well as monthly income (p=0.03), website preference categories (p=0.02). Male students were significantly more likely to gain higher P-EHEALS scores.
    CONCLUSION: The level of E-Health literacy was low in Medical and Health Sciences university students in Mashhad. More studies are needed to assess the contributors to E-Health literacy.

    Introduction: Considering physical and emotional changes affecting women's sexual function in postpartum period.

    Aim: This study was conducted to determine the sexual dysfunction and postpartum-related factors in Bandar Abbas women in 2016.

    Material and Methods: This analytical cross-sectional study used systematic random sampling on 432 postpartum women referred to Bandar Abbas Healthcare Centers. Data were collected by Demographic and Obstetrics Questionnaire and Female Sexual Function Index (FSFI) Questionnaire through interview and were analyzed by using SPSS ver.22 method.

    Results: The overall rate of sexual dysfunction was reported 85.95%. The most common postpartum sexual dysfunction was pain sexual dysfunction during sexual intercourse. The mean score of all types of sexual dysfunction increased over time after delivery except sexual satisfaction so that the mean score of sexual satisfaction did not show significant differences over time. There was a significant relationship between sexual dysfunction with factors such as duration of marriage (p< 0.001), number of children (p<0.001), familial relationship (p=0.028), episiotomy status (P=0.002) and contraceptive method (p=0.001).

    Conclusion: Considering the high prevalence of sexual disorders in this study, healthcare systems need to pay more attention to this area. In order to promote the health status of the family and ultimate of the society, attention to sexual health as well as the early diagnosis and treatment of sexual dysfunction of couples are important, especially during pregnancy and after childbirth.

    Childbirth is one of the most important influencing factors for sexual function. Therefore, this study was conducted with the aim of comparing sexual function in primiparous and multiparous women. This cross-sectional analytical study was performed using systematic random sampling on 420 women in the postpartum period who referred to Bandar Abbas health Centres in 2018. The data were collected using an interview method which consisted of a Female Sexual Function Index questionnaire and a demographic questionnaire. The data analysis was performed using the SPSS Version 23 software. The results showed that sexual dysfunction was lower in multiparous women compared to primiparous women (p = .006). Low sexual activity in primiparous women can be due to less privacy and more time and energy loss. Several factors including housing situation, monthly income, episiotomy incision, and the education level of the couple were influential in the sexual function of the primiparous women (p

    OBJECTIVE: The aim of this overview was to evaluate the effectiveness of phytoestrogens on vaginal health and dyspareunia in peri- and post-menopausal women.

    MATERIAL AND METHODS: Three databases including MEDLINE, Scopus and the Cochrane Central Register of Controlled Trials were from inception to August 2017.

    RESULT: Two systematic reviews and 11 RCTs were included in the overview. According to the findings, isoflavones increased the maturation value and attenuated the vaginal atrophy in the post-menopausal women. Topical isoflavones had beneficial effects on the vaginal atrophy. Similar efficacy was found in Pueraria mirifica and conjugated estrogen cream on dryness ( p = 0.277), soreness ( p = 0.124) and irritation ( p = 0.469), as well as discharge ( p = 0.225) and dyspareunia ( p = 0.089). However, the conjugated estrogen cream was more effective compared to Pueraria mirifica ( p > 0.005) regarding maturation index improvement. Comparison of fennel 5% vaginal cream and placebo gel showed significant difference in superficial cells ( p

    Objectives: The present mini review aimed to summarize the existing knowledge regarding the beneficial and adverse effects of raloxifene in menopausal women.

    Methods: This study is a review of relevant publications about the effects of raloxifene on sleep disorder, depression, venous thromboembolism, the plasma concentration of lipoprotein, breast cancer, and cognitive function among menopausal women.

    Results: Raloxifene showed no significant effect on depression and sleep disorder. Verbal memory improved with administration of 60 mg/day of raloxifene while a mild cognitive impairment risk reduction by 33% was observed with administration of 120 mg/day of raloxifene. Raloxifene was associated with a 50% decrease in the need for prolapse surgery. The result of a meta-analysis showed a significant decline in the plasma concentration of lipoprotein in the raloxifene group compared to placebo (standardized mean difference, -0.43; 10 trials). A network meta-analysis showed that raloxifene significantly decreased the risk of breast cancer (relative risk, 0.572; 95% confidence interval, 0.327-0.881; P = 0.01). In terms of adverse effects of raloxifene, the odds ratio (OR) was observed to be 1.54 (P = 0.006), indicating 54% increase in the risk of deep vein thrombosis (DVT) while the OR for pulmonary embolism (PE) was 1.05, suggesting a 91% increase in the risk of PE alone (P = 0.03).

    Conclusions: Raloxifene had no significant effect on depression and sleep disorder but decreased the concentration of lipoprotein. Raloxifene administration was associated with an increased risk of DVT and PE and a decreased risk of breast cancer and pelvic organ prolapse in postmenopausal women.

    BACKGROUND: Sexual dysfunction refers to a chain of psychiatric, individual, and couple's experiences that manifests itself as a dysfunction in sexual desire, sexual arousal, orgasm, and pain during intercourse. The aim of this systematic review will be to assess the sexual dysfunction and determine the relevant factors to sexual dysfunction during pregnancy and postpartum.

    METHODS AND ANALYSIS: All observational studies, including descriptive, descriptive-analytic, case-control, and cohort studies published between 1990 and 2019, will be included in the study. Review articles, case studies, case reports, letter to editors, pilot studies, and editorial will be excluded from the study. The search will be conducted in the Cochrane Central Register, MEDLINE, Google Scholar, EMBASE, ProQuest, Scopus, WOS, and CINAHL databases. Eligible studies should assess at least one of the sexual dysfunction symptoms in pregnant women or in the first year postpartum. Quality assessment of studies will be performed by two authors independently based on the NOS checklist. This checklist is designed to assess the quality of observational studies. Data will be analyzed using Stata software ver. 11. Considering that the index investigated in the present study will be the level of sexual disorder, standard error will be calculated for each study using binomial distribution. The heterogeneity level will be investigated using Cochran's Q statistic and I2 index in a chi-square test at a significance level of 1.1. Predictable limitations of this study included a small number and unacceptable quality of studies.

    DISCUSSION: This systematic review addresses the factors associated with sexual dysfunction during pregnancy and postpartum. Considering the high prevalence of sexual dysfunction among women, the treatment of this problem has been highly sought after by the World Health Organization in recent years. The results of this study can help discover new strategies by introducing factors affecting women's sexual dysfunction, thereby eliminating or diminishing these factors, and play an important role in improving the quality of life of women during pregnancy and postpartum periods.

    BACKGROUND: The participation of women in cervical cancer screening in Malaysia is low. Self-sampling might be able to overcome this problem.The aim of this study was to assess the reliability of self-sampling for cervical smear in our country.

    MATERIALS AND METHODS: This cross-sectional study was conducted on 258 community dwelling women from urban and rural settings who participated in health campaigns. In order to reduce the sampling bias, half of the study population performed the self-sampling prior to the physician sampling while the other half performed the self-sampling after the physician sampling, randomly. Acquired samples were assessed for cytological changes as well as HPV DNA detection.

    RESULTS: The mean age of the subjects was 40.4±11.3 years. The prevalence of abnormal cervical changes was 2.7%. High risk and low risk HPV genotypes were found in 4.0% and 2.7% of the subjects, respectively. A substantial agreement was observed between self-sampling and the physician obtained sampling in cytological diagnosis (k=0.62, 95%CI=0.50, 0.74), micro-organism detection (k=0.77, 95%CI=0.66, 0.88) and detection of hormonal status (k=0.75, 95%CI=0.65, 0.85) as well as detection of high risk (k=0.77, 95%CI=0.4, 0.98) and low risk (K=0.77, 95%CI=0.50, 0.92) HPV. Menopausal state was found to be related with 8.39 times more adequate cell specimens for cytology but 0.13 times less adequate cell specimens for virological assessment.

    CONCLUSIONS: This study revealed that self-sampling has a good agreement with physician sampling in detecting HPV genotypes. Self-sampling can serve as a tool in HPV screening while it may be useful in detecting cytological abnormalities in Malaysia.

    BACKGROUND: Polycystic ovary syndrome (PCOS) is a combination of chronic anovulation, obesity, and hyperandrogenism and can affect sexual function in women of reproductive age. It is also associated with endometrial cancer. Our aim was to evaluate the frequency and predisposing factors of sexual dysfunction in PCOS patients.

    MATERIALS AND METHODS: In this cross-sectional study, 16 married women with a definite diagnosis of PCOS were recruited. Sexual function was assessed in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain using the female sexual function index (FSFI) questionnaire. Patients were also assessed for mental health using the depression, anxiety and stress (DASS-21) questionnaire. Presence of hirsutism was assessed using the Ferriman-Gallwey (FG) scoring system. Demographic data were obtained from patients during in-person interview.

    RESULTS: Sexual dysfunction was present in 62.5% of patients with the domains of arousal and lubrication particularly affected (93.8% and 87.5%, respectively). Patients with symptoms of depression and anxiety were significantly more likely to suffer sexual dysfunction than those without these symptoms (p=0.04 and p=0.03 respectively). Patients with stress symptoms reported higher orgasm dysfunction than those without (p=0.02). No significant difference in any of the FSFI score domains was observed between patients with and without hirsutism.

    CONCLUSIONS: PCOS patients markedly suffer from sexual dysfunction and therefore it seems appropriate to be screened for intervention. Poor mental health conditions that may be the result of infertility or other complications of PCOS should also be considered as curable causes of sexual dysfunction in these patients.

    Objective: Polycystic ovarian syndrome (PCOS) is a common condition amongst women of reproductive age that can result in increased mortality and morbidity in women due to increased risk of diabetes mellitus and cardiovascular diseases. The aim of this systematic review was to assess the effectiveness of common treatments of PCOS on the predictors of diabetes in non-diabetic PCOS women. Materials and methods: An extensive search was performed on the publications in three medical databases including pubmed, scopus and google scholar from 1995 till 2017. The articles were screened based on their quality and included in this systematic review. A total of 25 articles including cohort, randomised controlled trial, review and meta-analysis were included in the review. Results: This systematic review revealed that the effect of lifestyle modification might be low in PCOS subjects due to high drop-out rate while the benefits of this intervention including weight and fat reduction may not be achieved by medical interventions. Metformin treatment may result in improvements in insulin sensitivity while its weight reduction effect is still not documented in PCOS subjects. Thiazolidendiones might be tolerated by the PCOS subjects and may result in similar effects as metformin but this effect should be documented by further studies. Conclusion: Combination of lifestyle modification with metformin or thiazolidinedions might improve the outcome of the prevention strategies. On the other hand this study revealed a different response to treatments in non-obese compared with obese PCOS subjects.

    Alcohol consumption is associated with higher risk of breast cancer (BC); however, the biological mechanisms underlying this association are not fully elucidated, particularly the extent to which this relationship is mediated by sex hormone levels. Circulating concentrations of estradiol, testosterone, their free fractions and sex-hormone binding globulin (SHBG), were examined in 430 incident BC cases and 645 matched controls among alcohol-consuming postmenopausal women nested within the European Prospective Investigation into Cancer and Nutrition. Mediation analysis was applied to assess whether individual hormone levels mediated the relationship between alcohol intake and BC risk. An alcohol-related hormonal signature, obtained by partial least square (PLS) regression, was evaluated as a potential mediator. Total (TE), natural direct and natural indirect effects (NIE) were estimated. Alcohol intake was positively associated with overall BC risk and specifically with estrogen receptor-positive tumors with respectively TE = 1.17(95%CI: 1.01,1.35) and 1.36(1.08,1.70) for a 1-standard deviation (1-SD) increase of intake. There was no evidence of mediation by sex steroids or SHBG separately except for a weak indirect effect through free estradiol where NIE = 1.03(1.00,1.06). However, an alcohol-related hormonal signature negatively associated with SHBG and positively with estradiol and testosterone was associated with BC risk (odds ratio [OR] = 1.25 [1.07,1.47]) for a 1-SD higher PLS score, and had a statistically significant NIE accounting for a mediated proportion of 24%. There was limited evidence of mediation of the alcohol-BC association by individual sex hormones. However, a hormonal signature, reflecting lower levels of SHBG and higher levels of sex steroids, mediated a substantial proportion of the association.
