ABSTRACT
Exercise is an integral component of physical and mental health. Attention to exercise in women, regarding their physiologic situation is essential. This study aimed to investigate the effect of a specific aerobic exercise program on fetal growth in pregnant women. In this clinical trial, 39 pregnant women in 24-32 weeks of gestation were enrolled. The participants were randomly allocated to experimental [n=18] and control [n=21] groups. Women with single pregnancies and intact amniotic membranes were included. Women who had any contraindications for exercise were excluded from the study. Exercise program included stretching and flexibility exercise and aerobic exercise [constant walking for 30-45 minuets] three days a week for eight weeks. Data were analyzed using descriptive statistics, c[2], t-test, Kolmogro-smirnov and repeated measurements. P<0.05 was considered to be significant. The results showed a 1.37% increase in the newborns' weight in the intervention group; however, the difference was not statistically significant. The average of head circumference and newborns' length in the intervention group's newborns were 0.21cm and 0.09cm more than the control group's newborns, respectively. These differences were not statistically significant too [P>0.05]. There were no reductions in the growth of the fetuses following the exercise activities. This kind of exercise has no adverse effect on fetal growth

Among all occupation, the highest rate of musculoskeletal injuries especially back pain is seen in nurses. The purpose of this study was to determine the prevalence of back injuries in nursing personnel and to study how individual and occupational characteristics affect it. Following ethical approval, 1226 nurses were randomly selected from 13 hospitals in Mazandaran province in the north of Iran. Data were gathered by questionnaires included individual and occupational characteristics, prevalence of back pain, probable causes and its effects on nursing activities. Point, one month, 6 month, one year and lifetime prevalence of LBP [Low back pain] in nurses reported 51.5%, 56.3%, 58.9%, 59.6% and 62%, respectively. Lifting heavy things was the most common cause of back injury [30.4%]. Prolonged standing and rest were found to be the significant aggravating and relieving factors, respectively [57.6% and 59.2%]. Absence from work because of LBP during the last month was reported 33.7% of the sample. There was a significant correlation between the type of ward and LBP [P<0.001], the highest prevalence of LBP was in emergency ward and the lowest one was in NICU and urology ward. There was also a reverse correlation between job satisfaction and prevalence of LBP in nurses [P<0.001]. The results demonstrate that the magnitude of LBP amongst nursing personnel appears to be high and associated with some occupational and individual characteristics. Therefore, more resources should be allocated to prevent such an injury in nursing profession
ABSTRACT
Low back pain [LBP] is common in youth, although `associated with chronic pain in adults. The purpose of this study was to determine the prevalence and risk factors of LBP in school children age 11-14. A cross sectional study was carried out on school children aged 11-14 in north of Iran. Using random multistage sampling 5000 children were selected. Demographic, mechanical and lifestyle data as well as the prevalence and LBP characteristics were collected by a questionnaire. Data analysis was carried out using SPSS [version11] software. Of the original sample, 4813 [96.2%] children returned the questionnaire. Point, last month, last 6 months and annual prevalence were 15%, 14.4%, 15.6%, and 17.4%, respectively. LBP was significantly correlated with age [p<0.05], lifting [p<0.05], position and duration of watching TV, doing homework and duration of exercise [p<0.05]. The results indicated that the prevalence of LBP in school children is relatively high. Further studies evaluating the effect of different preventive strategies to reduce the prevalence of LBP in school children is strongly recommended
