Prevalence of Depression among Iranian Elderly: Systematic Review and M

Objective: depression is one of the most serious and prevalent mood disorders. Aging population is an important economic, social, and health challenge of the 21st century. The present study aimed at estimating the prevalence of depression among the Iranian elderly through meta-analysis method. Method: Studies were searched in ISI, Scopus, Pub Med, Google Scholar, and in Iranian databases including Iran Medex, Magiran, SID, and Med Lib using the following keywords: "depression", "prevalence", and "elderly". Data were analyzed using meta-analysis (random effects model). Heterogeneity among the results of the studies was examined by "I2" index. Beck, DASS-21, GHQ-28, and G DS questionnaires were used in this study, and analyses were performed using STATA Ver.11. Results: A total of 26 studies in Iran with a sample size of 5781 individuals had been found during 2001 and 2015. Prevalence of depression among Iranian elderly was estimated to be 43% (95% confidence interval (CI):30% - 55%). The findings showed that the prevalence of depression among Iranians were49% in women, 48% in men, 37% in unmarried, and 45%in the married. In addition, the prevalence of very severe, severe, moderate, and mild depression levels were estimated to be 5%, 19%, 33%, and 38% of the participants, respectively. No significant difference was observed between married and unmarried individuals. Most of Iranian elderly suffered from mild depression. Conclusion: There was high level of depression prevalence among Iranian elderly, and women were more depressed than men. So, policy makers must design and run mental health programs to decrease the prevalence of depression among Iranian elderly

Effect of Palliative Care on Quality of Life and Survival after Cardiopulmonary Resuscitation: A Systematic Review

Background: Cardiac and respiratory arrest is reversible through immediate cardiopulmonary resuscitation (CPR). However, survival after CPR is very low for various reasons. This systematic review study was conducted to assess the effect of palliative care on quality of life and survival after CPR. Methods: In the present meta-analysis and systematic review study, two researchers independently searched Google Scholar and MagIran, MedLib, IranMedex, SID, and PubMed for articles published during 1994–2016 and containing a number of relevant keywords and their Medical Subject Headings (MeSH) combinations. A total of 156 articles were initially extracted. Results: The success of initial resuscitation was reported to be much higher than the success of secondary resuscitation (survival until discharge). Moreover, the early detection of cardiac arrest, a high-quality CPR, immediate defibrillation, and effective postresuscitation care improved short- and long-term outcomes in these patients and significantly affected their quality of life after CPR. Most survivors of CPR can have a reasonable quality of life if they are given proper follow-up and persistent treatment. Conclusions: Concerns about the low quality of life after CPR are therefore not a worthy reason to end the efforts taken for the victims of cardiac arrest. More comprehensive education programs and facilities are required for the resuscitation of patients and the provision of post-CPR intensive care. Keywords: Cardiopulmonary resuscitation, palliative care, postcardiopulmonary resuscitation survival, quality of lif

Prevalence of obesity in Iranian children: Systematic review and meta-analysis

Background of the Study: Childhood obesity, in addition to the likelihood of its continuation in adulthood, is associated with an increase in mortality and various diseases. Purpose of the Study: This meta-analytic study aimed at determining the prevalence of obesity among Iranian children. Methodology: Two researchers independently searched national and international databases using MeSH, Scopus, PubMed, Science Direct, Web of Science, Springer, Magiran, Iranmedex, SID, Medlib, and the Google Scholar search engine. The heterogeneity between studies was evaluated using the P index. Data were analyzed using STATA software. This study was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Results: Among 93 studies with a sample size of 3,845,768, the prevalence of obesity in Iranian children was 7% (girls 8% and boys 10%), and the prevalence of overweight was 12% (girls 17% and boys 15%). The incidence rate of obesity in children was 13% based on US centers for disease control and prevention (CDC) 2000 reference, 11% on international obesity task force (IOTF) reference, 9% on World Health Organization reference, 9% on Iranian reference, 5% on CDC reference, and 3% on national center for health statistics (NCI IS) reference. Meta-regression diagram also showed that the prevalence of obesity in children was not dependent on sample size. However, the prevalence of obesity declined during the years 1999-2016, which was statistically significant. Conclusion: The prevalence of obesity in Iranian children was less than of their overweight. On the other hand, the prevalence of childhood obesity in girls was lower than that of boys, and the prevalence of child overweight among girls was higher than that of boys

Investigating the prevalence rate of hypertension in Iranian men and women: A study of systematic review and meta-analysis

Introduction: Based on the serious complications which are followed, hypertension is a common and asymptomatic health problem. This study aims to present a general statistics of the rate of the prevalence of systolic and diastolic hypertension in Iranian men and women based on the age range through the systematic review and meta-analysis method. Materials and methods: In this study of systematic review and meta-analysis, some databases such as Google Scholar, Scope.com, Magiran, Iran Medex, Medlib, Sid, and Pubmed were searched by using keywords such as hypertension, men and women, Iran, and prevalence. The first and the last published articles in this field were in 1999 and 2012, respectively. Data were combined by random effects meta-analysis model and they were analyzed by STATA11. Results: From 100 articles which were found in the searched references, 22 of them were finally analyzed. Among the selected final articles from 1999 to 2012, 96689 subjects were used in this study. The mean prevalence of hypertension was 17% (confidence coefficient of 95%, 17-17%). The prevalence rate of hypertension among the people above 20 was between 10-32% and its mean was 24% (confidence coefficient of 95%, 23-24%). The mean prevalence of hypertension among the people below 20 was 5% (confidence coefficient of 95%, 4-5%). Conclusion: In the studies done in Iran, the prevalence rate of hypertension was high. Noticing that hypertension is an important and dangerous factor for cardiovascular diseases, it is a worrying issue in Iran and it is necessary to be programmed in order to control and prevent this disease

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% and7.4%, 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

Phototherapy Effects on Zinc Level of Neonates With Hyperbilirubinemia: A Systematic Review and Meta-analysis

Background: Phototherapy is the most common treatment of neonatal jaundice that affects the zinc level as well as the bilirubin level. Objectives: The purpose of this study is to investigate the effect of phototherapy on the zinc level of infants with jaundice by a systematic review and meta-analysis. Methods: In this systematic review and meta-analysis a comprehensive literature search of the databases, including Cochrane Library, Web of Science, PubMed, Scopus, and Google Scholar web browser was conducted using standard keywords. Data analysis of this meta-analysis was performed using STATA software, version 14 and P<0.05 was considered a significant level for tests.  Results: In the five studies reviewed in this article with a sample size of 398 individuals, phototherapy increased the level of zinc [Standardized mean difference (SMD): 0.88 (95% CI: 0.38, 1.38), P<0.001] and decreased bilirubin level [SMD: -7.67 (95% CI: -9.11, -6.23), P<0.001] in infants with jaundice. The effect of phototherapy was on the zinc level of these groups: infants with a birth weight of 3000 to 3300 grams (gr) [SMD: 1.07 (95% CI: 0.42, 1.71), P<0.001] and 3301 to 3600 gr [SMD: 0.40 (95% CI: -0.32, 1.12), P=0.028], three-day-old infants [SMD: 1.05 (95% CI: 0.35, 1.74), P<0.001], four-day-old [SMD: 0.76 (95% CI: 0.26, 1.32)], and 5-day-old ones [SMD: 0.23 (95% CI: -0.01, 0.48)]. In addition, phototherapy affected on zinc level of those whose gestational age (GA) was 37 [SMD: 1.12 (95% CI: 0.06, 2.17), P<0.001] and 38 [SMD: 0.61 (95% CI: 0.15, 1.06), P=0.001] weeks. Conclusions: Phototherapy by reducing the level of bilirubin increases the level of zinc in infants with jaundice. So, the standardized mean difference of “phototherapy effects on the zinc level of infants with jaundice” decreases with increasing infants’ weight, increasing infants’ age, and increasing gestational age

Prevalence of Hypertension in Renal Diseases in Iran: Systematic Review and Meta-Analysis.

BACKGROUND: Hypertension is a risk factor for renal disease. Therefore, this study was aimed at estimating the prevalence of hypertension in renal patients in Iran through meta-analysis. METHODS: The search was carried out using authentic Persian and English keywords in national and international databases including IranMedex, SID, Magiran, IranDoc, Medlib, ScienceDirect, Pubmed, Scopus, Cochrane, Embase, Web of Science, Medline, and Google Scholar search engine without any time limitation until 2017. Heterogeneity of studies was assessed using the I 2 index. Data were analyzed using STATA ver 11. RESULTS: In 35 reviewed studies with a sample of 39,621 subjects, the prevalence of hypertension in renal patients was 35% (95% CI: 29%-41%) (25% in women and 18% in men). The prevalence of systolic hypertension in renal patients was 5%, diastolic hypertension 26%, and diabetes 23%. The prevalence of hypertension in hemodialysis patients was 34%, 27% in peritoneal dialysis, 43% in kidney transplantation, and 26% in chronic renal failure. In addition, meta-regression showed that the prevalence of hypertension in renal patients did not significantly decrease during the years 1988-2017. CONCLUSIONS: More than a third of kidney patients in Iran suffer from high blood pressure. The diastolic blood pressure of these patients is about five times higher than their systolic blood pressure. Moreover, the age group under 30 is a high-risk group. The prevalence of hypertension in women with kidney disease is higher than in men. In addition, patients who have kidney transplants are more likely to have high blood pressure than other kidney patients. KEYWORDS: Hypertension; Iran; kidney disease; meta-analysis; renal diseas
