The impact of combined administration of surfactant and intratracheal budesonide compared to surfactant alone on bronchopulmonary dysplasia (BPD) and mortality rate in preterm infants with respiratory distress syndrome: a single-blind randomized clinical trial.

BACKGROUND: Respiratory distress syndrome (RDS) is one of the most important and common disorders among premature infants. OBJECTIVE: This study aimed to compare the effect of the combination of surfactant and budesonide with surfactant alone on Bronchopulmonary dysplasia (BPD) and mortality rate among premature infants with RDS. METHOD: An outcome assessor-blind randomized clinical trial was conducted on 134 premature infants with RDS who were born in Ayatollah Mousavi Hospital, Zanjan, Iran in 2021. The covariate adaptive randomization method was utilized to allocate participants into two groups (surfactant alone and a combination of surfactant and budesonide). The primary outcomes were BPD and Mortality rate from admission to hospital discharge. The data in this study were analyzed using SPSS software version 18. RESULTS: Overall the comparison of mortality rate and BPD between the two groups did not show a significant difference(p > 0.05). The subgroup results showed that administering surfactant with budesonide to infants under 30 weeks of age significantly reduced the number of deaths compared to using surfactant alone (5 vs. 17). Similar positive effects were observed for the occurrence of Pulmonary Hemorrhage, the need for a second dose of surfactant, oxygen index, mean blood pressure and mean arterial pressure (MAP) in infants under 34 weeks of age compared to more than 34 weeks (p < 0.05). CONCLUSION: These findings suggest that the combination therapy of surfactant and budesonide may be beneficial, particularly in preterm infants with less than 34 weeks gestational age and 1500 birth weight. However, further studies with larger sample sizes and longer follow-up periods are needed to confirm these results and assess long-term outcomes. TRIAL REGISTRATION: The study was registered at the Iranian Registry of Clinical Trials website under the code IRCT20201222049802N1. https://en.irct.ir/user/trial/48117/view .

Association between Vitamin D Insufficiency and Respiratory Problems in Premature Neonates.

BACKGROUND: Few studies have been performed to investigate the association between vitamin D and respiratory problems in premature neonates. METHODS: In this cohort study, a low serum level of vitamin D was considered as exposure and respiratory problems and associated interventions were considered as outcome. All patients were followed during their hospital stay. All preterm neonates admitted to the neonatal intensive care unit of a general hospital in Iran during one-year period from January 2018 were enrolled in this study. Serum vitamin D level was measured in the first 24 hours of life by liquid chromatography-spectrometry. Then, respiratory complications were compared between neonates with and without vitamin D insufficiency. RESULTS: Among the 113 preterm newborns, 65 (58%) had a low and 48 (42%) had a normal level of vitamin D who were classified into two groups I and II, respectively. Respiratory distress syndrome (RDS) and requirement for surfactant administration was found in 40 cases (61.5%) in group I and in 20 cases (41.7%) in group II (P=0.036). Also, 46 newborns (70.8%) in the first group and 22 (45.8%) in the second group needed non-invasive ventilation (NIV) (P=0.007). Multiple logistic regression showed a significant association between vitamin D status and RDS (OR, 95% CI=2.840 (1.083-7.447), P=0.034), need for surfactant (OR, 95% CI=2.840 (1.083-7.447), P=0.034) and need for NIV (OR, 95% CI=3.929 (1.526-10.113), P=0.005). CONCLUSION: The incidence of RDS, need for surfactants, and need for NIV in newborns with vitamin D insufficiency were higher than the neonates with normal levels.

The solutions to increase the participation of men in sexual and reproductive health of women in Iran: an analytic hierarchy process (AHP) analysis.

Ever since the Cairo Declaration in 1994, women's Sexual and Reproductive Health (SRH) has become a priority and substantial efforts have been made to improve it. Men's contribution to promote the SRH of women is essential. Therefore, this study aimed to identify the best solutions to increase the men's participation in the SRH of women in Iran, using an analytic hierarchy process (AHP) approach. A cross-sectional study was conducted among 150 married men in Iran. The data was collected using a questionnaire. To determine the best solutions to improve the men's participation in women's SRH, the opinions of an expert group from academia, Ministry of Health (MOH) were employed and the best solution were selected based on the scores, applying analytic hierarchy process (AHP) approach. The statistical analysis was performed using SPSS V.20 and Expert Choice software. In the final analysis 'Well-oriented sex education focused on men's involvement', 'Well-trained professional employment' and 'Sex education in society, schools, and universities' were the solutions with highest coefficients, respectively.Impact statementWhat is already known on this subject? SRH of women, is a major part of primary efforts regarding the increase of SRH's quality; among which, the role and place of men is of utmost importance. Struggling to participate men in issues related to the health of women can not only promote inter family relationships, but also can affect the quality of relationship between man and woman in the society.What do the results of this study add? According to results of the study, one of the main obstacles of men participation was educational and information barriers, regarding which, having adjusted and improved educational systems, opportunity could be prepared for men participation. Current centres for educating those who are already getting married are the first and main places where men can be educated to meet their educational needs in their marriage life such as SRH. Through integrating three selected approaches in the experts' meetings in the educational program of before marriage, men participation can be increased in SRH.What are the implications of these findings for clinical practice and/or future research? The findings could inform and guide the policies in formulating effective solutions to improve the men's participation in SRH in Iran.

Epidemiological and clinical characteristics of the COVID-19 epidemic and associated factors for mortality in Golestan province, Iran: a retrospective cohort study.

BACKGROUND: We aimed to further clarify the epidemiological and clinical characteristics of 2019-nCoV pneumonia and risk factors associated for mortality. METHODS: In this study, we included inpatient with acute respiratory distress syndrome at Golestan Hospitals who had been discharged or had died in 2020. Epidemiological, and clinical data were extracted from electronic medical records and compared between recovered and died cases. We used multiple logistic regression methods to explore the risk factors associated with in-hospital death. RESULTS: Overall 2,835 acute respiratory distress syndrome patients were included in this study, and 874 (30.83%) were positive for 2019-nCoV. Five hundred and sixty-three patients (19.86%) died, 1,687 patients (59.51%) were recovered. Of the total deaths, only 288 (10.15%) were attributed to COVID-19. The most common symptoms at onset of illness were respiratory distress [1,795 (63.32%)], fever [1,601 (56.47%)], dry cough [1,595 (56.26%)], sore throat [445 (15.70%)], and myalgia [342 (12.06%)]. One thousand and twelve (35.7%) had 1 or more coexisting medical conditions. In multiple logistic regression analysis, risk factors associated with the death included older age [OR (Odds Ratio) = 1.03; 95% CI; 1.02-1.04], blood oxygen level (SPO2 < 93%) (OR = 2.44; 95% CI; 1.79-3.31), comorbidities (OR = 2.15; 95% CI; 1.62-2.84), respiratory distress (OR = 1.74; 95% CI; 1.28-2.37), and headache (OR = 0.44 95% CI; 0.21-0.92). CONCLUSIONS: The 2019-nCoV infection caused collections of severe respiratory illness and was associated to a high ratio of hospitalization in ICU and high mortality. Older age and comorbidities were associated with more risk of death among patients with 2019-nCoV.

Integrating Mental Health Services into the Primary Health Care System: The Need for Reform in Iran.

Objective: The main objective of this study was to review aspects of the current situation and structure of the integrated mental health care services for planning a reform. Aspects of the newly designed infrastructure, along with specification of duties of the various human resources, and its relation with Iran's Comprehensive Mental and Social Health Services (the SERAJ Program), will also be presented Method : This is a study on service design and three methods of literature review, deep interview with stakeholders, and focused group discussions. In the literature review, national and international official documents, including official reports of the World Health Organization (WHO) and consultant field visits, were reviewed. Deep semi-structured interviews with 9 stakeholders were performed and results were gathered and categorized into 3 main questions were analyzed using the responsibility and effectiveness matrix method. The Final results were discussed with experts, during which the main five-domain questions were asked and the experts' opinions were observed. Results: In this study, the main gaps of the public mental health care (PHC) services in Iran were identified, which included reduction of risk factors for mental disorders, training the general population, early recognition and treatment of patients with mental disorders, educating patients and their families, and rehabilitation services. The new model was then proposed to fill these gaps focusing on increasing access, continuity of care, coordination in service delivery, and comprehensiveness of care. A mental health worker was placed besides general healthcare workers and general practitioners (GPs). Services were prioritized and the master flowchart for mental health service delivery was designed. Conclusion: A reform was indeed necessary in the integrated mental health services in Iran, but regarding the infrastructure needed for this reform, including human and financial resources, support of the senior authorities of the Ministry of Health (MOH) is necessary for the continuity and enhancement of services. In this model, attention has been given to the principles of integrating mental health services into primary health care. Current experience shows that the primary health care system has been facing many executive challenges, and mental health services are not exclusion to this issue. Monitoring and evaluation of this model of service and efforts for maintaining sustainable financial resources is recommended to make a reform in this system and to stabilize it.

How is insulin-like growth factor-1 correlated with retinopathy of prematurity?

BACKGROUND: Evaluation of insulin-like growth factor-1 (IGF-1) association with retinopathy of prematurity (ROP) is our object. MATERIALS AND METHODS: This study was conducted on IGF-1 levels of 40 neonates <34 weeks gestational age and 2000 g at 1st week and 4-6 weeks after birth. All participants were evaluated for ROP after 31 weeks of gestation. RESULTS: IGF-1 levels showed a significant difference between neonates ≤1500 and 1500-2000 g (1 and 4-6 weeks, P = 0.008, P = 0.039, respectively). No significant association was found between IGF-1 and ROP. CONCLUSION: Finding a meaningful association between IGF-1 and ROP requires consideration of factors affecting the IGF-1.

Perceived strategies to reduce traumatic childbirth amongst Iranian childbearing women: a qualitative study.

BACKGROUND: Psychological birth trauma (PBT), mainly due to overlooking maternal mental health, is a common and high prevalence public health problem in low-resource settings. Preventing PBT is a good indicator of the realization of human rights in healthcare. This work reports the results of a qualitative study that aimed to identify perceived strategies of PBT prevention among childbearing women in Iran. METHODS: We conducted semi-structured in-depth interviews with 22 mothers with history of traumatic childbirth, two mothers with positive childbirth experience, two spouses, and eight health professionals between April and June 2017. We used purposive sampling method to recruit traumatized mothers, while health experts were selected based on their relevant expertise and experience. Our initial literature review identified eight categories, using which we developed our interview guide and conducted the content analysis approach. RESULTS: With the maximum possible purification, we reached 50 thematic codes. The strategies to prevent PBT are generally summarized in four major themes and 13 categories: 1) skill-builder knowledge [Birth preparedness, Mothers' empowerment in maintaining mental health, Understanding the importance of mental care in maternity services], 2) responsible caregiving [Support loop, Good behavior of the caregivers, Deepening trust, Struggle with medicalization of childbirth, Labour pain relief, Special services for maternal mental health], 3) the alliance of prenatal and antenatal care [Continuity of care, Coordination of prenatal and antenatal caregivers], and 4) reconstruction of the structures [Efficient management, Rebuilding physical structures]. CONCLUSIONS: This is a comprehensive approach towards PBT prevention, which can guide future efforts to reduce PBT at the clinical level and open further avenues for future studies. We recommend policy makers to consider the integration of multilevel and multidimensional PBT prevention interventions, simultaneously within maternity care services packages for promotion of mental health.

Novel coronavirus in a 15-day-old neonate with clinical signs of sepsis, a case report.

Introduction: Novel coronavirus or coronavirus disease (COVID-19) can affect all age groups. The clinical course of the disease in children and infants is milder than in adults. It should be noted that, although typical symptoms may be present in children, non-specific symptoms could be noted in the neonate. The disease is rare in the neonate, so, its suspicion in this group can help to make a quick diagnose.Case report: A 15-day-old neonate was admitted with fever, lethargy, cutaneous mottling, and respiratory distress without cough. His mother had symptoms of Novel coronavirus. So Reverse-Transcription Polymerase Chain Reaction (RT-PCR) assay was done for the neonate and showed to be positive. The newborn was isolated and subjected to supportive care. Antibiotic and antiviral treatment was initiated. Eventually, the baby was discharged in good general condition.Conclusion: When a newborn presents with non-specific symptoms of infection with an added history of COVID-19 in his/her parents, it indicates the need for PCR testing for Novel coronavirus.

Creating a positive perception of childbirth experience: systematic review and meta-analysis of prenatal and intrapartum interventions.

BACKGROUND: A negative experience in childbirth is associated with chronic maternal morbidities. The aim of this systematic review and meta-analysis was to identify currently available successful interventions to create a positive perception of childbirth experience which can prevent psychological birth trauma. METHODS: Randomized controlled trials of interventions in pregnancy or labour which aimed to improve childbirth experience versus usual care were identified from 1994 to September 2016. Low risk pregnant or childbearing women were chosen as the study population. PEDRO scale and Cochrane risk of bias tool were used for quality assessment. Pooled effect estimates were calculated when more than two studies had similar intervention. If it was not possible to include a study in the meta-analysis, its data were summarized narratively. RESULTS: After screening of 7832 titles/abstracts, 20 trials including 22,800 participants from 12 countries were included. Successful strategies to create a positive perception of childbirth experience were supporting women during birth (Risk Ratio = 1.35, 95% Confidence Interval: 1.07 to 1.71), intrapartum care with minimal intervention (Risk Ratio = 1.29, 95% Confidence Interval:1.15 to 1.45) and birth preparedness and readiness for complications (Mean Difference = 3.27, 95% Confidence Interval: 0.66 to 5.88). Most of the relaxation and pain relief strategies were not successful to create a positive birth experience (Mean Difference = - 2.64, 95% Confidence Intervention: - 6.80 to 1.52). CONCLUSION: The most effective strategies to create a positive birth experience are supporting women during birth, intrapartum care with minimal intervention and birth preparedness. This study might be helpful in clinical approaches and designing future studies about prevention of the negative and traumatic birth experiences.

Job Burnout, Job Satisfaction, and Related Factors among Health Care Workers in Golestan Province, Iran.

INTRODUCTION: Burnout causes physical and emotional tireness, job dissatisfaction, resulting in reduced efficiency and a feeling of alienation from colleagues. Also, job satisfaction has a major impact on job-related behaviors, such as turnover intention, absenteeism, and job performance. The aim of this study was to determine job burnout, job satisfaction rate, and related factors among health care workers in Golestan Province in Iran. METHODS: This cross-sectional study was conducted with 1,141 health workers in Golestan Province in northern Iran. Data were collected using a questionnaire that was comprised of four sections. It consisted of socio-economic characteristics, physical environment and facilities of health house (rural health clinic), Maslach burnout inventory, and a satisfaction questionnaire. Multi-nomial Logistic Regression was conducted to analyze the data using SPSS software, version 22. RESULTS: There were significant relationships between the intensity of job burnout and age (p < 0.001), years of experience (p < 0.001), low education level (p = 0.027), number of children (p = 0.002), dissatisfaction with income (p < 0.001), physical environment of health houses (p = 0.003), facilities of health houses (p = 0.025). There were significant relationships between the frequency of job burnout and age (p < 0.001), years of experience (p < 0.001), low education level (p = 0.016), number of children (p = 0.003), dissatisfaction with income (p < 0.001), and the physical environment of health houses (p = 0.008). There were significant relationships between job satisfaction and the satisfaction from income (p = 0.001), the physical environment of health houses (p = 0.001), and the facilities of health houses (p = 0.001). CONCLUSION: Burnout was average among health workers, and health workers job satisfaction rate was lower than the average level in health workers. Effective interventions are recommended with regards to the unfavorable condition of job satisfaction and its relationship with job burnout.

Inequality in Utilization of In-patients Health Services in Iran.

BACKGROUND: Health services for those in need. Inpatient care shows a more serious side of individual care and patients and their family members perceive a high level of stress and urge. We conducted this study to determine inequalities of in-patient health care utilization in Iranian people and to assess factors that influence utilization. METHODS: In each province, the sample was comprised of 380 urban and 380 rural households that were recruited by a systematic random sampling method. A total of 23,560 households, which included around 102,000 individuals were recruited. We used the questionnaire for data collection. Met admission need (MAN) was the main variable and was considered household assets for determining the economic status. We did all analyses using the STATA version 9.1. RESULTS: The rates of MAN for urban and rural areas were 83% and 81.3% respectively. The rate of MAN was significantly higher in patients with higher educational level. Patients with primary health insurance coverage had significantly higher rate of MAN. CONCLUSIONS: Meeting admission needs was estimated around 84% and it seems that modifying insurance coverage is the most feasible intervention for increasing utilization of health services.

Application of Capture-Recapture for Fine-tuning Uncertainties About National Maternal Mortality Estimates.

BACKGROUND: Maternal mortality ratio (MMR) is one of the main indicators of the millennium development goals and its accurate estimation is very important for the countries concerned. The objective of this study is to evaluate the applicability of capture-recapture (CRC) as an analytical method to estimate MMR in countries. METHODS: We used the CRC method to estimate MMR in Iran for 2004 and 2005, using two data sources: The maternal mortality surveillance system and the National Death Registry (NDR). Because the data registry contains errors, we defined three levels of matching criteria to enable matching of cases between the two systems. Increasing the matching level makes the matching criteria less conservative. Because NDR data were missing or incomplete for some provinces, we calculated estimates for two conditions: With and without missing/incomplete data. RESULTS: According to the CRC method, MMR in 2004 and 2005 were 33 and 25 in the best-case scenarios respectively and 86 and 59 in the worst-case scenarios respectively. These estimates are closer to the ones reported by United Nations Agencies published in 2010, 38 and Hogan's study, 30 in 100,000 live births in 2005. CONCLUSIONS: The MMR estimation by CRC method is slightly different from the international studies. CRC can be considered as a cost-effective method, in comparison with cross-sectional studies or improvement of vital registration systems, which are both costly and difficult. However, to achieve accurate estimates of MMR with CRC method and decrease the uncertainty we need to have valid databases and the absence of such capacities will limit the applicability of this method in developing countries with poor quality health databases.

Drug Literacy in Iran: the Experience of Using "The Single Item Health Literacy Screening (SILS) Tool".

Drug and health literacy is a key determinant of health outcomes. There are several tools to assess drug and health literacy. The objective of this article is to determine drug literacy level and its relationships with other factors using a single item screening tool. A cross-sectional survey was conducted among 1104 people in Qazvin province, Iran. Based on the proportional-to-size method, participants over 15 years old with ability to read were recruited randomly from 6 counties in Qazvin province and were interviewed directly. To determine drug literacy relationship with other variables, Chi-Square and t-test were used. Also, logistic regression model was used to adjust the relationship between drug literacy and other relevant variables. Response rate in clusters was 100%. Findings showed that inadequate drug literacy in Qazvin province is 30.3% and it was in association with (1) age (p = .000), (2) marital status (p = .000), (3) educational attainment (p = .000), (4) home county (p = .000), (5) residing area (p = .000), (6) type of basic health insurance (p = .000), (7) complementary health insurance status (p = .000), and (8) family socioeconomic status (p = .000). After adjusting for these variables using logistic regression model, the association between (1), (3), (4), (5) and (8) with drug literacy level was confirmed. The analysis also showed that this method can also be used in other health care settings in Iran for drug and health literacy rapid assessment.

Why caution is recommended with post-hoc individual patient matching for estimation of treatment effect in parallel-group randomized controlled trials: the case of acute stroke trials.

A post-hoc individual patient matching procedure was recently proposed within the context of parallel group randomized clinical trials (RCTs) as a method for estimating treatment effect. In this paper, we consider a post-hoc individual patient matching problem within a parallel group RCT as a multi-objective decision-making problem focussing on the trade-off between the quality of individual matches and the overall percentage of matching. Using acute stroke trials as a context, we utilize exact optimization and simulation techniques to investigate a complex relationship between the overall percentage of individual post-hoc matching, the size of the respective RCT, and the quality of matching on variables highly prognostic for a good functional outcome after stroke, as well as the dispersion in these variables. It is empirically confirmed that a high percentage of individual post-hoc matching can only be achieved when the differences in prognostic baseline variables between individually matched subjects within the same pair are sufficiently large and that the unmatched subjects are qualitatively different to the matched ones. It is concluded that the post-hoc individual matching as a technique for treatment effect estimation in parallel-group RCTs should be exercised with caution because of its propensity to introduce significant bias and reduce validity. If used with appropriate caution and thorough evaluation, this approach can complement other viable alternative approaches for estimating the treatment effect.

Six-fold difference in the stomach cancer mortality rate between northern and southern Iran.

BACKGROUND: Stomach cancer is the most common cancer in Iran. A multi-ethnic population and wide variation in the environmental risk factors may lead to variations in cancer risk within this country. We have designed an ecological study and evaluated geographical variation regarding mortality from stomach cancer and its established risk factors in Iran.  METHODS: We used the Iranian National Causes of Death Registry and estimated the age-standardized mortality rates (ASMR) of stomach cancer in 29 Iranian provinces, stratified by sex and area of residence (rural/urban).  RESULTS: The average ASMR of stomach cancer among Iranian males was 15 per 100,000 and for females it was 8.1 per 100,000. The highest and lowest mortality rates were observed in Kurdistan with an ASMR of 29.1 per 100,000 in northwestern Iran and Hormozgan that had an ASMR of 5.0 per 100,000 in southern Iran. Males had approximately a two-fold higher ASMR compared to females, as did rural residents when compared with urban residents. The prevalence of H. pylori infection was about 90% in the province of Ardabil (a high-risk area) and 27% in the province of Sistan-Baluchistan (a low-risk area).  CONCLUSIONS: The wide geographical variation and high mortality rate of stomach cancer in Iran is likely due to differences in the exposure to the environmental risk factors among people living in the high- and low-risk areas, particularly H. pylori infection, a well-established risk factor of stomach cancer.

The burden of injuries in Iranian children in 2005.

BACKGROUND: Child injury is recognized as a global health problem. Injuries caused the highest burden of disease among the total population of Iran in 2003. We aimed to estimate the morbidity, mortality, and disease burden caused by child injuries in the 0- to 14-year-old population of Iran in 2005. METHODS: We estimated average age- and sex-specific mortality rates for different types of child injuries from 2001 to 2006 using Iran's death registration data. Incidence rates for nonfatal outcomes of child injuries in 2005 were estimated through a time- and place-limited sample hospital registry study for injuries. We used the World Health Organization's methods for estimation of years of life lost due to premature mortality and years lived with disability in 2005. RESULTS: Injuries were the most important cause of death in children ages 1 to 14, with 35, 33.4, 24.9, and 22.9 deaths per 100,000 in the 0-14, 1-4, 5-9, and 10-14 age groups respectively. Road transport injuries were responsible for the highest death rate per 100,000 population among all types of injuries in children, with 15.5 for ages 0-14, 16.1 for ages 1-4, 16.3 for ages 5-9, and 13.1 for ages 10-14. Incidence rates of injuries leading to hospitalization were 459, 530, and 439 per 100,000 in the 0-14, 1-4, and 5-14 age groups respectively. Incidence rates of injuries leading to outpatient care were 1,812, 2,390, and 1,650 per 100,000 in the same age groups respectively. Among injury types, falls and burns had the highest hospitalization and outpatient care incidence rates. CONCLUSIONS: Injuries, particularly road transport injuries, were the most important health problem of children in Iran in 2003 and 2005. Strong social policy is needed to ensure child survival.

High prevalence of vitamin D deficiency among pregnant women and their newborns in an Iranian population.

BACKGROUND AND OBJECTIVE: Vitamin D deficiency during pregnancy has important health implications for the mother and infant. This study was designed to determine the prevalence of hypovitaminosis D in pregnancy and to examine the probable correlation between serum concentrations of 25-hydroxyvitamin D [25(OH)D] in maternal blood and in neonates' cord blood. As yet, few studies have examined this phenomenon in the Iranian population; thus, this research adds to a small body of literature. METHODS: Sixty-seven full-term pregnant mothers were enrolled serially from a referring general hospital in Zanjan, a province located west of Tehran. All participating mothers delivered their babies via typical vaginal delivery. Samples of maternal and cord blood were collected on the day of delivery. Serum concentrations of calcium, phosphorus, 25(OH)D and alkaline phosphatase were measured in the samples. 25(OH)D concentrations <25 nmol/L were considered to be indicative of hypovitaminosis D. RESULTS: Mean maternal serum 25(OH)D was 19.4 +/- 3.9 nmol/L, and cord blood 25(OH)D was 16.7 +/- 2.9 nmol/L. Hypovitaminosis D was detected in 86% of the women and in 75% of the newborns during winter and 46% of the mothers and 35% of the newborns during summer. A positive correlation was found between maternal and cord blood 25(OH)D (r = 0.55, p < 0.001). CONCLUSIONS: We observed a high prevalence of physiologically significant hypovitaminosis D among pregnant women and their newborns, the magnitude of which warrants public health intervention.

The burden of disease and injury in Iran 2003.

BACKGROUND: The objective of this study was to estimate the burden of disease and injury in Iran for the year 2003, using Disability-Adjusted Life Years (DALYs) at the national level and for six selected provinces. METHODS: Methods developed by the World Health Organization for National Burden of Disease (NBD) studies were applied to estimate disease and injury incidence for the calculation of Years of Life Lost due to premature mortality (YLL), Years Lived with Disability (YLD), and DALYs. The following adjustments of the NBD methodology were made in this study: a revised list with 213 disease and injury causes, development of new and more specific disease modeling templates for cancers and injuries, and adjustment for dependent comorbidity. We compared the results with World Health Organization (WHO) estimates for Eastern Mediterranean Region, sub-region B in 2002. RESULTS: We estimated that in the year 2003, there were 21,572 DALYs due to all diseases and injuries per 100,000 Iranian people of all ages and both sexes. From this total number of DALYs, 62% were due to disability premature deaths (YLD) and 38% were due to premature deaths (YLL); 58% were due to noncommunicable diseases, 28% - to injuries, and 14% - to communicable, maternal, perinatal, and nutritional conditions. Fifty-three percent of the total number of 14.349 million DALYs in Iran were in males, with 36.5% of the total due to intentional and unintentional injuries, 15% due to mental and behavioral disorders, and 10% due to circulatory system diseases; and 47% of DALYs were in females, with 18% of the total due to mental and behavioral disorders, 18% due to intentional and unintentional injuries, and 12% due to circulatory system diseases. The disease and injury causes leading to the highest number of DALYs in males were road traffic accidents (1.071 million), natural disasters (548 thousand), opioid use (510 thousand), and ischemic heart disease (434 thousand). The leading causes of DALYs in females were ischemic heart disease (438 thousand), major depressive disorder (420 thousand), natural disasters (419 thousand), and road traffic accidents (235 thousand). The burden of disease at the province level showed marked variability. DALY estimates by Iran's NBD study were higher than those for EMR-B by WHO. CONCLUSION: The health and disease profile in Iran has made the transition from the dominance of communicable diseases to that of noncommunicable diseases and road traffic injuries. NBD results are to be used in health program planning, research, and resource allocation and generation policies and practices.

Adverse health outcomes of road traffic injuries in Iran after rapid motorization.

Recent studies have made it clear that Iran has too many road traffic injuries (RTI). This paper explains the reasons for high traffic injury rates and points to solutions. It also provides detailed data on the burden of traffic injury in Iran in 2005. Traffic injury rates have rapidly risen out of control because for a variety of possible reasons such as increasing number of non-standard cars and motorcycles, low gas price, decreasing ratio of travels via public transportation than with private vehicles, and problems with safety design. Besides a high need for a system safety approach, Iran needs to deal with the problem of producing a high number of cars and motorcycles. Providing safe mobility for the people of Iran needs to be a top priority of the government.

Impact of misclassification on measures of cardiovascular disease mortality in the Islamic Republic of Iran: a cross-sectional study.

OBJECTIVE: To assess the extent and pattern of misclassification of death from non-specific diagnoses emanating from the Iranian death registration system, and to correct the data for health policy and planning. METHODS: Detailed medical records for 1426 hospital deaths classified to seven ill-defined or vague causes of death were reviewed by trained physicians, who then completed standard death certificates. Underlying causes of death from the review were compared with the cause assigned in registration data. FINDINGS: The probable underlying pattern of causes of death in the Islamic Republic of Iran is substantially different to that suggested by the death registration system. About 88% of 582 cases with non-specific diagnoses at ages 15-69 years were reassigned to various specific causes including ischaemic heart disease (33%), stroke (13%) and injuries (10%). A similar pattern of misclassification is apparent for 738 deaths at older ages (70 years and over), with 46% being reassigned to ischaemic heart disease and stroke. CONCLUSION: A significant proportion of deaths in the Iranian death registration system are being classified to cause groups of little relevance to epidemiological research or health policy. Reassignment of these deaths would increase the proportion of deaths from ischaemic heart disease and cerebrovascular diseases each by 32%, diabetes mellitus by 68% and chronic lower respiratory diseases by 73%. Substantial changes to procedures for diagnosing causes of death are urgently required if registration data are to effectively guide health policies and programmes in the Islamic Republic of Iran.
