The relationship between emotional intelligence, spiritual intelligence, and student achievement: a systematic review and meta-analysis.

INTRODUCTION: Emotional and spiritual intelligence are crucial factors in enhancing individuals' knowledge and academic achievement. This study aims to examine the correlation between spiritual intelligence, emotional intelligence, and student achievement through a systematic review and meta-analysis. MATERIALS AND METHODS: A search was conducted in the PubMed, Scopus, Web of Science, SID, and Google Scholar databases from 2007 to December 2022. The effect sizes (EF) included the mean and standard deviation of emotional intelligence, spiritual intelligence, and student achievement and correlation coefficients among spiritual intelligence, emotional intelligence, and student achievement. Random effects models were used to pool the results, and the Q test and I2 index were employed to assess heterogeneity. Correlation coefficients were transformed into standard data (Z) using log transformation. RESULTS: The overall mean score of educational achievement in university and school students was 15.91 (95% CI: 15.26-16.78). The mean scores of spiritual and emotional intelligence were 138.27 (95% CI: 129.19-147.35) and 128.94 (95% CI: 117.08-140.80), respectively. The correlation coefficients between spiritual intelligence, emotional intelligence, and student achievement were r = 0.36 (95% CI: 0.18-0.51) and r = 0.50 (95% CI: 0.28-0.67), respectively. CONCLUSIONS: Emotional and spiritual intelligence are independent predictive factors in educational achievement for university and school students. Therefore, improvements in emotional and spiritual intelligence can promote students' academic achievement.

The prevalence of depression, anxiety and stress in nurses working in Iranian hospitals: A systematic review and meta-analysis.

INTRODUCTION: Depression, anxiety, and stress are common problems among nurses. OBJECTIVE: This meta-analysis was conducted to investigate the prevalence of depression, anxiety, and stress among nurses working in Iranian hospitals. MATERIALS AND METHODS: Published studies on nurses working in Iranian hospitals were investigated in this meta-analysis. All national and international online databases, including Web of Science, PubMed, Scopus, Embase, Cochrane Library, Scientific Information Database (SID), MagIran, and IranMedex, as well as Google Scholar, were searched using related keywords without any time limits until September 2017. The heterogeneity of studies was assessed using the I2 index. Data were analyzed in STATA version 11.1. RESULTS: In 28 studies with a sample size of 6581 people, the prevalence of depression was 31% (n=2040) among Iranian nurses (31% in females and 28% in males) according to Beck's Depression Inventory (BDI); 30% (n=1974) (54% in females and 40% in males) according to the 21-Item Depression, Anxiety and Stress Scale (DASS-21); and 9% according to the General Health Questionnaire (GHQ-28). The prevalence of mild, moderate, and severe depression in nurses was 39%, 16%, and 20% according to the BDI; 8%, 24%, and 4% according to DASS-21; and 48%, 36%, and 16% according to GHQ-28, respectively. The prevalence of anxiety and stress was 85% and 67% in Beck's inventory, 28% and 38% in DASS-21, and 46% and 49% in GHQ-28, respectively. CONCLUSION: According to the BDI and DASS-21, about one-third of Iranian nurses have depression with a female predilection. Nurses play an essential role in improving the quality of treatment; therefore, health policymakers must pay attention to reducing depression among nurses.

Prevalence of obesity and overweight in Iranian students: a systematic review and meta-analysis.

Background Obesity and overweight are among the most common and serious health issues in many countries, leading to numerous medical consequences such as heart disease, hypertension, fatty liver etc. This review article addressed the prevalence of obesity and overweight in Iranian students by using meta-analysis. Methods A number of domestic and international databases were searched, including IranMedex, Magiran, SID, Scopus, PubMed, IranDoc, Web of Science and Google Scholar. Eligible publications were 160 articles that addressed the prevalence of obesity or overweight. Data were combined using random effects model. Heterogeneity of the studies was examined by Q statistics and the I2 index. Data were analyzed using STATA version 11.1. Results In the 160 reviewed studies, a total of 481,070 individuals (6-20 years) were included. The prevalence of obesity among Iranian students based on body mass index (BMI) was 11% (95% confidence interval [CI]: 10%-12%) (in girls 8% [95% CI: 7%-10%] and in boys 11% [95% CI: 10%-13%]). The prevalence of overweight in students based on BMI was 12% (95% CI: 12%-13%) (in girls 13% [95% CI: 11%-14%] and in boys 11% [95% CI: 18%-30%]). The rate of obesity was 13% (95% CI: 11%-16%) in elementary school students, 10% (95% CI: 7%-14%) in secondary school students and 7% (95% CI: 6%-9%) in high school students. Conclusions The prevalence rate of overweight was more than that of obesity with a 1% difference. The prevalence of obesity was higher in boys, while the prevalence of overweight was higher in girls. The prevalence of obesity was higher in primary school students than in secondary school students. This prevalence was higher in secondary school students than in high school students.

The Prevalence of Sleep Apnea in Iran: a Systematic Review and Meta-Analysis.

BACKGROUND: Sleep apnea is a common sleep disorder which is associated with cardiovascular diseases, diabetes and stroke. Different studies conducted in Iran have reported different prevalence for sleep apnea. The aim of the present study was to determine the prevalence of sleep apnea in Iran. MATERIALS AND METHODS: In this study, 42 studies that have been published in Farsi and English languages were selected with no time limit up to the March of 2018. Article search was conducted using "prevalence", "frequency", "sleep apnea" and "obstructive sleep apnea" keywords in Scientific Information Database (SID), MagIran, Google Scholar, Science Direct, PubMed and Scopus databases. Data were analyzed using meta-analysis and random effect model methods. Heterogeneity between the studies was evaluated using I2 test. Data were analyzed using Stata software version 11.2. RESULTS: The total prevalence of metabolic syndrome was 44% (95% CI: 35% to 53%). The highest prevalence of sleep apnea distinguished by the disease belonged to patients with sleep disorders (74%, 95% CI: 66%-82%), diabetes mellitus (61%; 95% CI: 46%-76%) and cardiovascular disease (55%; 95% CI: 47%-63%). CONCLUSION: Given high prevalence of sleep apnea in Iran, identifying people at risk and providing instructional materials for controlling and treating sleep apnea is necessary.

Estimation of Mean Intelligence Quotient with Wechsler Scale in Iran: Systematic Review and Meta-Analysis.

The low intelligence quotient (IQ) level is one of the most common and important medical, social, and familial problems in all countries. The current study aimed to estimate mean IQ with the Wechsler scale in Iran by performing a systematic review and meta-analysis. In the current meta-analysis, all articles related to IQ conducted in Iran using the Wechsler scale were deeply searched by reviewing citation databases including Science Direct, PubMed, Scopus, Web of Science, Springer, SID, Magiran, Iranmedex, Medlib, and Google Scholar motor search and using valid keywords without time limits. Due to heterogeneity between studies, a random effects model was used to combine the results of studies. To investigate the heterogeneity of the studies, the I2 index was used. All statistical analyses were performed using STATA software version 11.1. The number of participants in the 51 studies was 5352. The mean total IQ score in Iran was estimated 97.12 (95% confidence interval [CI]: 88.71-105.52), the practical intelligence was 92.84 (95% CI: 79.14-106.55), and the verbal intelligence was 94.50 (95% CI: 83.90-105.10). The total IQ score in the northern, southern, central, eastern, and western regions of Iran was 97.08, 108.90, 92.31, 101.76, and 96.45, respectively. The mean IQ score in Iran in subjects under 20 years of age is 97.73 and in subjects over 20 years of age is 105.61. There is also no significant relationship between the mean total IQ in Iran and two parameters of the year of research and number of research samples. For prevention of decrease IQ and given that proper nutrition and breastfeeding directly contribute to increase IQ, nutrition should be provided free of charge in poorer areas during pregnancy until baby born. Moreover, the media should provide adequate education for breastfeeding and nutrition, because IQ affects people's academic, occupational, personal, and social performance, and also prevents elite immigration with suitable planning and provides conditions for elites to return to the country.

Prevalence of pterygium in Iran: a systematic review and meta-analysis study.

BACKGROUND AND AIM: Pterygium is one of the most prevalent pathologies involving the cornea, which can lead to various vision signs and even reduction in eyesight. No accurate estimate has been reported about the prevalence of pterygium in Iran. Hence, this study aimed to determine the pterygium prevalence in Iran by meta-analysis method. METHODS: Searching for data of the last eleven years (from 2004 to 2015) was conducted using the keywords of pterygium, eye, and Iran in International and domestic indexing services and databases including Iranmedex, Scientific Information Database (SID), Magiran, Irandoc, Medlib, IranPsych, Science Direct, Web of Science (Thomson Reuters), PubMed, and Scopus. The data were analyzed using the meta-analysis method (the random effects model). The disharmony of the studies was investigated using the I2 index. The data were analyzed by STATA Ver.11 software. RESULTS: In 5 studies conducted in Iran, with a sample size of 10,838 people between 2004 and 2015, the extent of the prevalence was estimated to be 11% (95% CI: 3 to 18%). Also, the prevalence of pterygium in women and men was 18% and 13%, respectively. CONCLUSION: According to the published reports from Iran and its comparison with other points in the world, the prevalence of pterygium in Iran is high, especially among women.

Investigation of the Prevalence of Obesity in Iran: a Systematic Review and Meta-Analysis Study.

Obesity is one of the main public health problems which underlie many chronic illnesses and socioeconomic difficulties. According to the literature review, there are limited data on the prevalence of obesity in different parts of Iran as well as its trend and prevalence among different age and gender groups. The aim of this study was to estimate the obesity prevalence in Iran using meta-analysis. All the corresponding articles published in the external and internal journals, final reports of research projects, articles of related congresses and the reference index of the correlated papers published between 1995 and 2010 were collected via the electronic research engines (PubMed, Scopus, SID, Magiran, IranMedex). Data were analyzed using meta-analysis (random effects model) and meta-regression). A total of 144 articles with the sample size of 377858 people (134588 males and 164858 females) were enrolled in the study. The prevalence of obesity in populations above the age of 18 was estimated as 21.7% (CI 95%: 18.5% - 25%) and in populations below 18 as 6.1% (CI 95%: 6.8%-5.4%). Meta-regression analysis showed an ascending trend in the prevalence of obesity in Iran. The prevalence rates of obesity according to the BMI index, NCHC and percentile above 95 were 17.4%, 7.6% and 7.4%, respectively. The BMI mean was 19.3 in populations below the age of 18 (CI 95%: 17-21.6) and 25.2 in those above the age of 18 (CI 95%: 27.1-23.3). Considering the increasing rate of obesity in Iran and its effects on the public health, corresponding health authorities should revise the obesity preventive programs and, using public health interventions, reduce the rate of obesity in the country.

The Relationship Between Religious Attitudes, Fear of Death and Dying with General Health Condition: A Survey in College Students.

This study aims to assess the relationship between religious attitudes of Ilam universities students (west of Iran), their perspectives about the fear of self and other's death and dying, with their general health. This paper is an analytic survey in which 351 college students, who were selected by multistage sampling, participated. To measure interested variables, Persian format of standardized self-administered questionnaires was employed. Religious attitudes with odds ratio (OR) of 0.94 (95% CI 0.91-0.97) and fear of self dying with 0.88 (95% CI 0.81-0.96) were identified as a protective factors against the inappropriate general health condition. However, the fear of other's death (OR 1.16; 95% CI 1.05-1.28) was identified as a risk factor. This study showed that people who had more religious attitudes and fear of self dying had better general health as well as the fear of other's death had a significant direct relationship with inappropriate general health condition.

Economic factors influencing mental health using multiple regression model in Ilam province of Iran.

BACKGROUND: Mental disorder is one of the most important diseases of which is predicted to increase from 10.5% to 15% until 2020. This study aimed to determine economic factors influencing mental health using multiple regression models in Ilam province in 2013. METHODS: In this cross sectional study, 903 families from different cities of Ilam were selected using multistage cluster sampling. The families were selected from each city separately and each head of family was interviewed. The instruments for data collection included general and economic questionnaires and the General Health Questionnaire (GHQ). The data were analyzed using SPSS software version 21, Eviews, t-test, ANOVA, Pearson's correlation coefficient, single and multiple linear regressions. RESULTS: The mean ± SD mental health score in this study was 28.5±12.10. The mental health increased for 4.26 units per each unit of life satisfaction increase, decreased for 4.09 units per each unit of gender growth, increased for 2.94 units per each unit of increase in economic status and had a significant correlation with all the three components (p<0.001). CONCLUSION: In order to improve people's mental health, it is recommended that healthcare officials may more attention to this matter through implementation of programs such as life skills' training, stress resistance skills training, and helping individuals to be able to adapt themselves to their life environment.
