Background and Aim: Physical activity during pregnancy is one important facet of women's health behavior and Lifestyle, it cause to improvement body image, reduction physical discomfort, anxiety and insomnia, and also has beneficial effects on women's delivery and breast feeding. Despite the great benefits of physical activity, it is often weak in pregnant women. The aim of this study was to develop a protocol to remove barriers of physical activity in healthy pregnant women admitted to Shahid Beheshti Health Center and Hospital in Isfahan. Materials and Methods:This is a descriptive study with Delphy method and information has been gathered in a triangulation way, which was conducted at Isfahan University of Medical Sciences and Shahid Beheshti Hospital in Isfahan. The second phase is a study that in the first phase of the cross-sectional and it was done on 380 pregnant women in 2015. At first, pregnant women completed demographic / reproductive, pregnancy physical activity questionnaire. Then the solutions to remove barriers of physical activity were provided by using the results of the first phase of study, library resources and internet and by performance the Delphi method by faculty members of Department of Midwifery, pregnant women and results of resources, was obtained .Statistical analysis by using descriptive statistical and SPSS statistical software (version 16) was done. The level of significance was set at (p≤ 0.05) for all the statistical tests.Results: Among 74 presented solutions, 61 approaches in the first and second stage in each fourth aspects; physical, psychological, environmental and social were 75th percentile score higher than 8. Conclusion:In order to promote and increase the amount of physical activity during pregnancy, attention and recommendation to implement this protocol in routine prenatal care is essential.

BackgroundThe ductus venosus pulsatility index(DVPI) has been evolved as an important marker of the first trimester screening sonography. The aim of this study is to define a reference for ductus venosus pulsatility index at 11–13 +6 weeks of gestation.MethodsIn this cross sectional observational study, 415 women with singleton pregnancies and crown lump length(CRL) between 45 and 84 mm were included. Exclusion criteria were abnormal biochemical screening results, presence of fetal structural malformation or chromosomal abnormalities such as thickened nuchal fold, abnormal perinatal outcomes, and newborns with a chromosomal abnormality. Transabdominal U/S was performed in all participants by an expert radiologist in obstetric sonography. CRL, nuchal translucency(NT), and blood flow indices of ductus venosus (DV) in each fetus were measured. The collected data were analyzed by IBM SPSS software version 20. Linear regression was performed to demonstrate the association between CRL DVPI. Further, 5th, 50th, and 95th percentiles of DV blood flow indices were calculated for each gestational age.ResultThe mean value of DVPI ranged from 1.05 at CRL 42mm to 1.3 at CRL 82mm. DVPI and CRL did not show any significant linear association (Regression coefficient B=0.001, R2=0.003, P=0.31)Conclusion: We defined means and ranges of DVPI, while determining the 5th, 50th, and 95th percentiles of DVPI for each CRL at our institution which were approximately similar to previous studies.
