- چکیده:
- چکیده انگلیسی: Background: The prevention and correction of vitamin D deficiency requires a precise depiction of the current situation and identification of risk factors in each region. The present study attempted to determine these entities using a systematic review and meta-analysis in Iran.Methods: Articles published online in Persian and English between 2000 and November 1, 2016, were reviewed. This was carried out using national databases such as SID, IranMedex, Magiran, and IranDoc and international databases such as PubMed, Google Scholar, and Scopus. The heterogeneity index among the studies was determined using the Cochran (Q) and I2 test. Based on the heterogeneity results, the random-effect model was applied to estimate the prevalence of vitamin D deficiency. In addition, meta-regression analysis was used to determine heterogeneity-suspected factors, and the Egger test was applied to identify publication bias.Results: The meta-analysis of 48 studies identified 18531 individuals with vitamin D deficiency. According to the random-effect model, the prevalence of vitamin D deficiency among male, female, and pregnant women was estimated to be 45.64% (95% CI: 29.63 to 61.65), 61.90% (95% CI: 48.85 to 74.96), and 60.45% (95% CI: 23.73 to 97.16), respectively. The results of the meta-regression analysis indicated that the prevalence of vitamin D deficiency was significantly different in various geographical regions (β=4.4; P=0.023).Conclusion: The results obtained showed a significant prevalence of vitamin D deficiency among the Iranian population, a condition to be addressed by appropriate planning.

- چکیده:
- چکیده انگلیسی: Objective(s):Helicobacter pylori (H. pylori) is a pathogenic bacterium that colonizes the stomachs of approximately 50% of the world’s population. Resistance of H. pylori to antibiotics is considered as the main reason for the failure to eradicate this bacterium. The aim of this study was to determine the rate of resistant H. pylori strains to various antimicrobial agents in different areas of Iran.
Materials and Methods: A systematic review of literatures on H. pylori antibiotic resistance in Iran was performed within the time span of 1997 to 2013. Data obtained from various studies were tabulated as following, 1) year of research and number strains tested, 2) number of H. pylori positive patients, 3) study place, 4) resistance of H. pylori to various antibiotics as percentage, and 5) methods used for evaluation of antibiotic resistance.
Results: Over the period, a total of 21 studies on H. pylori antibiotic resistance have been conducted in different parts of Iran. In these studies, H. pylori resistance to various antibiotics, including metronidazole, clarithromycin, amoxicillin, tetracycline, ciprofloxacin, levofloxacin and furazolidone were 61.6%, 22.4% ,16.0%, 12.2%, 21.0%, 5.3% and 21.6%, respectively. We found no study on H. pylori resistance to rifabutin in Iran.
Conclusion: Compared to the global average, we noted that the prevalence of H. pylori resistance to metronidazole, clarithromycin, amoxicillin, and tetracycline has been rapidly growing in Iran. This study showed that in order to determine an appropriate drug regimen against H. pylori, information on antibiotic susceptibility of the bacterium within different geographical areas of Iran is required.- انتشار مقاله: 06-11-1393

- چکیده:
- چکیده انگلیسی: Background: The users’ satisfaction is a method for evaluating the efficacy of healthcare system. We aimed to evaluate the association between the users’ socioeconomic status (SES) and satisfaction with the healthcare system in Shiraz, Iran.Methods: This cross-sectional study was conducted from December, 2013 to March, 2014, in Shiraz, Iran. 3400 households were recruited by multi-stage cluster random sampling. Information about demographic, insurance status, and users’ satisfaction was derived from face-to-face interviews. Satisfaction with healthcare system was assessed by using 5-point Likert scale statements, which ranged from “very dissatisfied” to “very satisfied”. All statistical analyses were performed using SPSS-21.Results: Overall, 1.6% (55) of the respondents were very satisfied, while 6% (203) were very dissatisfied with healthcare system. Participants were classified into high SES (26.3%), middle SES (47.9%) and low SES (25.8%). It was discovered that the better the SES, the more frequent were the respondents dissatisfied with healthcare system (P<0.001). Also, dissatisfied respondents were significantly older (P=0.036). Moreover, women were more dissatisfied with healthcare system (P=0.005). Also, dissatisfied respondents had significantly a higher level of education than satisfied ones (P<0.001). Furthermore, logistic regression revealed that age (P=0.04), marital status (P=0.01), insurance status (P<0.001), SES (P<0.001), and having supplemental insurance (P=0.02) were determinant factors of satisfaction with healthcare system. Conclusion: This study demonstrated that users’ sex, age, educational level, and SES were related to dissatisfaction with healthcare system. Meanwhile, clients’ age, SES, insurance status and marital status were recognized as determinant factors.

- چکیده:
- چکیده انگلیسی: Background: Although sleep disorders are common problems among families and they affect the learning, memory processes and academic performance of children, there is no evaluation of these disorders in Iran. The aim of this study was to assess the prevalence of sleep disorders and its association with academic performance of school age children.
Materials and Methods: A cross-sectional study was conducted on 1,100 middle school students of Isfahan city of Iran during 2012-2013. Multi-stage random cluster sampling method was performed and five girl’s schools and five boy’s schools were selected. The data gathered with a validated questionnaire to evaluate the academic performance and sleep disorders.
Results: The mean duration of nocturnal sleep was 8.38±1.17 which was significantly higher in the group with excellent academic performance (8.86±1.18 hours), than the other two groups (8.14±1.17 hours for average academic performance and 7.90±1.15 hours for poor academic performance). Academic performance was significantly associated with age, gender, parental occupation, nocturnal sleep time, sleep latency and sleep disorders (P<0.05).
Conclusion: This study revealed that sleep disorders negatively affect the academic performance and highlighted the importance of proper sleep among children and students.- انتشار مقاله: 26-10-1395
