Introduction: Migraine as one of the most common types of headaches with high prevalence has significant impact on the lives of patients.This study estimated migraine prevalence and clinical characteristics of migraine patients in Hamadan.

Methods: In this crossed- sectional study, all patients who referred to the neurology department of Sina Hospital from 2010.03. 21 to 2011.03.20 and confirmed by neurology specialists as migraine patients, were studied. Demographic data (age, sex, occupation), the scale migraine disability and clinical characteristics data were collected. The obtained information was analyzed by using SPSS 16 software descriptive statistics.

Results: During the study, 128 (12.8%) of the migraine patients referred to the neurology clinic. females constituted 68.7% of the patients. The average frequency of migraine attacks was 9.1 in a year. Pulse headache in 91 patients (85.1%) and one-sided headache in 79 patients (61.7%) were seen. Nausea and anorexia, respectively, the first (67.1%) and second (43.7%) had symptoms associated with migraine. Based on the obtained information from the mean MIDAS 53 (41.4%) of the patients with the average score of 23 showed severe performance degradation.

Conclusion: Findings related to the severity of headache after that loss of work to reflect the importance of the social impact of migraine and the need for making strategies for migraine prevention and treatment are very important. In other words, more attention should be paid to initial prevention, diagnosis and treatment.

Introduction: To identify early changes in growth and ensuring proper continued development of children, evaluation of development and improvement of children’s health is very importance. This study aims to evaluate the prevalence of stunting in first-grade students and its association to parental education, socioeconomic status and household size in Hamadan.

Methods: In this descriptive-analytical study, a number of 32 elementary schools were considered by cluster sampling method, in 2012. Required data was collected through 1257 first-grade students’ records in elementary schools. One way analysis of variance, Pearson correlation test and logistic regression were performed to analyze data using SPSS software version 16.

Results: The stunting prevalence was found 6 percent in Hamadan. Also, the results of this study didn’t show any significant association between father’s and mother’s occupation and household size with stunting in first-grade students (P<0.05). A significant association between education level of father and first-grade students’ stunting was seen (P=0.002, r=0.308). Moreover, significant correlation was recognized between education level of mother and stunting in children (P=0.001, r=0.388). Logistic regression represented an adjusted significant association between age and parental education level and stunting prevalence (P<0.05).

Conclusion: The results of this study showed that parental education level is highly associated with stunting in the first-grade students. In this regard, it is suggested that mass media, healthcare and educational centers personnel have interventions to increase awareness of parents.

Introduction: Musculoskeletal disorders (MSDs) are one of the main problems in workplaces, which cause loss of working time, absenteeism, reduced workers’ efficiency and increased service and production costs. The present study was carried out to investigate the prevalence of musculoskeletal disorders and their associated risk among office workers.

Methods: In this descriptive cross-sectional study one hundred and thirty three office workers of a huge construction company were involved. For collecting data related to musculoskeletal symptoms and to investigate the associated risk of these disorders the Nordic standard questionnaire and RULA method were used, respectively. Data were analyzed with chi-square test and multiple regressions by using SPSS software version 16.

Results: About 50% of the workers reported MSDs’ symptoms, during the past 12 months, at least in one region of musculoskeletal system. The highest prevalence belonged to lower back (42.1%), neck (33.1%), wrist (18%), and shoulders (11.3%), respectively. The prevalence of symptoms in the neck and lower back of workers, with more than 10 working hours per day, was statistically significant (P>0.001). Additionally, a statistically higher prevalence of symptoms in the neck, wrist, and lower back of workers with job tenure higher than 5 years was noted (P>0.05). The risk assessment revealed that all workers’ postures were fall into action levels of 2 and 3.

Conclusions: The findings revealed that MSDs symptoms have a high prevalence in office workers and the risk of these disorders is intermediate to high. Moreover, the main effective factors in the prevalence of MSDs symptoms were job tenure higher than 5 years and working hours more than 10 per day.

Introduction: Premenstrual syndrome (PMS) is a psycho-somatic problem, which occurs in the late phase of the menstrual cycle. Many women suffer from the symptoms of this syndrome. The aim of this study was to evaluate the frequency of PMS and its relationship with exercise among the students of Bushehr University of Medical Sciences.

Methods: A cross-sectional descriptive analytical study was designed in 2016 and 408 students were selected by the stratified random sampling from five faculties of Bushehr University of Medical Sciences. Data were collected through the standard premenstrual syndrome questionnaire (PMSQ) and international physical activity questionnaire (IPAQ). Descriptive statistics, ANOVA, independent sample t-test and Chi-square test were used to analyze the data.

Results: The mean age of the participants was 21.77± 2.45. And, the prevalence of PMS was 83.5%. Approximately 48, 41 and 11% of the participants had, respectively, weak, moderate and severe physical activity. There was no significant relationship between the frequency of PMS and physical activity (p=0.384), but the severity of anxiety (p=0.041), anger (p=0.012), migraine (p=0.018), abdominal blotting (p=0.042) decreased with doing physical activity.

Conclusion: The prevalence of PMS among the students was high. About half of them had weak physical activity. It seems that planning health education and physical activity programs can be effective in moderating the sumptoms of PMS.
