Introduction: Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health and increase the risk of more diseases in future. Body mass index (BMI) is a good method for measure the overweight and obesity and waist to hip ration is a good index for measure the abdominal obesity. Methods: This cross-sectional study was done on 1316 people who selected randomly from Ardabil city. Demographic data and anthropometric parameters such as age,sex, height, weight, waist circumference and hip circumference were measured by interviewers. Data were analyzed by statistical methods such as t-test, chisquare test, Pearson correlation and multinomial logistic regression model in SPSS version 21. Results: The mean age of the people was 28.5±7.4 years of them, 63.1% were in age group 20-30 years. The mean height of the samples was 162.7±8.6 cm in range 110-194 and the mean weight of them was 68.9±11.7 kg in range 43-111. The mean BMI of patients was 25.7. According to BMI, 35.6% of all samples had overweight and 18.6% had obesity. According to the WHR, 28.1% of male and 22.1% of female had high WHR (abdominal obesity). The prevalence of abdominal obesity based WHR was 25.2%. Conclusion: By using Multinomial Logistic Regression we showed that the relation between BMI and Age was positive and significant and by increasing one year at age of people, the rate of overweight increased 13% and the rate of obesity increased 17% in compare with normal patients.

Background: Ultrasonography (US) is the most important imaging modality in detecting both intrauterine and ectopic pregnancies. The aim of this study was to comparison transvaginal ultrasound with serum β-hCG level for diagnosis of ectopic pregnancy (Ep) in referred women to Ardabil city hospital.Methods: In this cross-sectional study, a total of 207 women with diagnosis of Ep were enrolled during 2018. All women underwent transvaginal US in the first 24 hours and US done by an expert radiologist. Serum levels of β-hCG at first 24 hours and the time gap between US examination and last menstrual period (LMP) were compared between women with positive and negative US findings. Data collected by a checklist and analyzed by statistical method in SPSS version 21.Results: The primary US were positive in 174 women (84.1%) and negative in 33 women (15.9%). The mean of time gap between US and LMP in women with diagnosed EP was significantly higher than other women (median, 42 days versus 45 days, p=0.042). Also, the mean of serum level of β-hCG had significant difference between two groups. In logistic regression analysis results showed that the time gap between US and LMP hadn’t significant impact on EP diagnosis. The best discriminative zone was set at a serum β-hCG level of 105.65 mIU/ml with a sensitivity and specificity of 82% and 27%, respectively and the under-ROC area was 58%.Conclusions: According to our findings, the median serum level of β-hCG in women with undiagnosed Ep were significantly lower than women with correct diagnosis of Ep but the mean and median of time gap between US and LMP in women with diagnosed EP was more than women without Ep. Also, the proposed discriminative zone for serum level of β-hCG in our study is different from the previous studies.

Background: Communication skills (CS) is an important topic which help the nurses and staff to maintain effective relationships and have professional standards in all legal, ethical and clinical areas. So low level of CS between nurses could be led to more medical mistakes and reduce the patient’s quality of care. The aim of this study was to determine the level of CS among Ardabil teaching hospitals nurses and staff and its related factors.Methods: This descriptive-analytical study was conducted on 145 Ardabil Alavi hospitals’ nurses and staff from May 2019 to November 2019. The data collection tool was communication skills questionnaire of Burton G (1990) which included demographic data and interpersonal communication skills test (18 items) with a range of 18-90. Data analyzed in SPSS version 21 by using descriptive and analytical statistics tests such as; Spearman, Mann-Whitney U, and Kruskal Wallis at significant level of p<0.05.Results: Of all students, 72.4% were women and the rest were men. The average age of participants, was 36.9±8.4 years. The mean score of total communication skills was calculated 59.2±7.3. The mean score of verbal skill, listening skill, and feedback skill were calculated in order to 20.8±3.43, 17.6±4, and 20.7±3.2, respectively. Total Communication skills was significantly related with past work experience but other demographic variables hadn’t significant relation with CS.Conclusions: The results indicated that the CS of Ardabil hospital nurses and staff were in moderate levels. So, providing training programs for raising their CS in future is essential.
