BackgroundObesity is one of the most important underlying risk factors for chronic disease. Dramatically increasing and following complication of obesity should be alerted to health politicians and practitioners to prevent associated health risks. This review aimed to give a better insight into the prevalence of obesity and overweight in different areas of Iran.MethodAll published internal (SID, Irandoc, Iranmedex), and international (Web of Knowledge, Pubmed, Scopus) source studies, reported the prevalence of overweight/obesity among normal population samples, during Jan 2005 through Jan 2014, were assessed in this review. Paper selection processes were done by two researchers separately. Studies which met the eligible criteria were included in this review.ResultOne hundred ninety three eligible studies enter into our review. Of 193 final selected studies, 86 (15 national, 71 sub national) of them were reported the prevalence of obesity/overweight in adult, and 107 studies (11 national, 96 sub national) in under-18 by individual. The range of overweight and obesity prevalence in national studies in adult, was 27.0-38.5 (95% CI: 26.8-27.1, 37.2-39.8), and 12.6-25.9 (95% CI: 12.2-13.0, 24.9-26.8), separately. In under-18 the range of overweight and obesity prevalence in national studies were 5.0-13.5 (95% CI: 4.5-5.5, 13.4-13.6), and 3.2-11.9 (95% CI: 3.0-3.4, 11.3-12.4).ConclusionObesity as an important public health problem has been discussed in recent few decades worldwide. Although the national reported prevalence of obesity in Iran was not considerably diverse, but remarkable differences were seen in the sub national prevalence which must be noticed more in political health programs especially among women and children.Electronic supplementary materialThe online version of this article (doi:10.1186/s40200-014-0121-2) contains supplementary material, which is available to authorized users.

Dysmenorrhea is common among women of reproductive age. This study aim was to investigate the effect of vitamin D (vit D) supplementation in treatment of primary dysmenorrhea with vit D deficiency. A randomized double-blind placebo-controlled clinical trial was conducted on 60 women with primary dysmenorrhea and vit D deficiency referred to our clinic at Arash Women's Hospital from September 2013 to December 2014. Eligible women were randomly assigned into treatment and control groups (30 in each group). Individuals in the treatment group received 50 000 IU oral vit D and the control group received placebo weekly for eight weeks. After two months of treatment, there was a significant difference in serum vit D concentration between the two groups (p < 0.001). Pain severity decreased significantly in treatment group after eight weeks of treatment. There was a significant difference in pain intensity between the two groups after eight weeks of treatment and one month after the end of treatment (p < 0.001 for both). A weekly high dose (50 000 IU) oral vit D supplementation for eight weeks in patients with primary dysmenorrhea and vit D deficiency could improve pain intensity.

Introduction: Mobile learning enables users to interact with educational resources while in variable locations. Medical students in residency positions need to assimilate considerable knowledge besides their practical training and we therefore aimed to evaluate the impact of using short message service via cell phone as a learning tool in residents of Obstetrics and Gynecology in our hospital. Methods: We sent short messages including data about breast cancer to the cell phones of 25 residents of gynecology and obstetrics and asked them to study a well-designed booklet containing another set of information about the disease in the same period. The rate of learning derived from the two methods was compared by pre-and post-tests and self-satisfaction assessed by a relevant questionnaire at the end of the program. Results: The mobile learning method had a significantly better effect on learning and created more interest in the subject. Conclusion: Learning via receiving SMS can be an effective and appealing method of knowledge acquisition in higher levels of education.

Worldwide, breast cancer is the most common malignant neoplasm and the second most common cause of cancer death in women. This malignancy is recognized to be estrogen-dependent and due to this feature, hormone replacement therapy is regarded as potentially dangerous in breast cancer survivors who seek relief of their menopausal symptoms. Whereas hot flashes are detected in nearly half of postmenopausal women with a relatively high frequency and severity, botanic sources of estrogens have been proposed as an alternative treatment. Nevertheless, estrogenic properties of these compounds suggest possibility of stimulating cancer recurrence or worsening prognosis in survivors. As well, effects in improving vasomotor climacteric changes is controversial. Many studies have considered the subject, some focusing on efficacy of phytoestrogens for control of menopausal symptoms, and others discussing effects of these compounds on breast cancer outcome in terms of survival or recurrence. The present article is a concise review of the effects of consumption of phytoestrogens on menopausal symptoms, namely hot flashes, and breast cancer recurrence and mortality in survivors of the disease. Overall, the major part of the current existing literature is in favor of positive effects of phytoestrogens on breast cancer prognosis, but the efficacy on menopausal symptoms is probably minimal at the best.

Results of the present study show that participants with short stature are at the greater risk of poor SRH and decreased LS in comparison with the subjects with normal height.
