Effort-reward imbalance and common mental disorders among public sector employees of Iran: a cross-sectional analysis.

BACKGROUND: The effort-reward imbalance (ERI) model is a widely used theoretical model to measure stress in the workplace. The objective of this study was to investigate the relationship between ERI and three common mental disorders: major depressive disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD). METHODS: In this cross-sectional analysis, the study sample consisted of 4453 baseline participants of the Employees' Health Cohort Study of Iran (EHCSIR). Trained psychologists utilized the Persian version of the Composite International Diagnostic Interview (CIDI-2.1) during the baseline assessment to identify common mental disorders. Additionally, the validated Persian version of the 23-item ERI questionnaire was employed to assess effort, reward, overcommitment, and effort-reward ratio. To examine the association of ERI components with three common mental disorders (MDD, GAD, and OCD) over the past twelve months, multiple logistic regression analyses were conducted. RESULTS: The prevalence of effort-reward imbalance in the study sample was 47.1%. Higher ERI score was significantly associated with MDD (OR: 3.43, 95% CI: 2.30-5.13), GAD (OR: 2.42, 95% CI: 1.27-4.63), and OCD (OR: 2.23, 95% CI:1.19-4.19). The study participants who reported higher scores on work overcommitment had a higher likelihood of having MDD (OR: 1.16, 95% CI:1.10-1.23), GAD (OR: 1.07, 95% CI: 1.01-1.14), and OCD (OR: 1.19, 95% CI: 1.09-1.29). CONCLUSIONS: According to the study's findings, work-related stress, as determined by the ERI model, is a significant factor in the development of common mental disorders among employees in the public sector.

Preexisting depression and COVID-19: a cohort study on the risk of susceptibility and hospitalization.

BACKGROUND: Depression can have negative effects on a person's physical health. However, the available evidence on the risk of susceptibility to COVID-19 and its adverse outcomes in people with mental disorders, including depression, is limited and inconsistent. Therefore, we investigated the relationship between major depressive disorder (MDD) and the risk of susceptibility to COVID-19 infection and hospitalization. The data used in the study were obtained from the Employees' Health Cohort Study of Iran (EHCSIR). METHODS: We conducted a cohort study that included 3355 participants who had complete data on major depressive disorder at baseline assessment and two annual telephone follow-ups between January 2020 and March 2022. Trained psychologists used the Persian version of the Composite International Diagnostic Interview (CIDI-2.1) to identify major depressive disorders during the baseline assessment. We applied log binomial regression models to adjust for sociodemographic factors and background health conditions. RESULTS: We found that 11.4% of participants had lifetime MDD and 7.3% had MDD in the past 12 months. During the pandemic, 26.1% of participants were infected with COVID-19, and 14.4% of those who were infected were hospitalized. The risk of susceptibility to COVID-19 infection was significantly higher among participants with lifetime MDD than among those without MDD (adjusted risk ratio (ARR) = 1.24, 95% CI: 1.06-1.47). However, lifetime MDD or 12-month MDD was not independently associated with hospitalization among COVID-19 cases. CONCLUSIONS: Preexisting major depressive disorder may increase the risk of susceptibility to COVID-19.

Reference interval of antithrombin, protein C, and protein S activities in healthy adults in Iran, the effect of age, sex, oral contraceptive intake, and menopause.

BACKGROUND: Antithrombin (AT), protein C (PC), and protein S (PS) are natural anticoagulant proteins that deficiency in each of them is associated with an increased risk of venous thromboembolism.The overlapping of plasma levels of AT, PC, and PS between healthy individuals and heterozygote carriers poses significant challenges in precise diagnosis. This study aimed to evaluate the effect of most influencing variables on plasma levels of these proteins and propose specific reference intervals to improve the interpretation of the laboratory results. METHODS: This study was conducted on 1464 individuals who were referred to Massoud medical laboratory, Tehran, Iran, from 2019 to 2020. AT and PC were measured through chromogenic assay and PS plasma level with the clot-based assay. A multivariable linear regression model was performed to evaluate the effect of sex, age, oral contraceptive (OCP) intake, and menopause state. Normal deviate z value was used for different subgroups to justify the need for a separate reference interval. RESULTS: 1200 verified healthy individuals (434 males and 766 females), aged between 18 and 69 years were included in the study. The mean ± SD age of the participants was 39.78 ± 11.79 years. The age-related effects for AT were found in men. In females, increasing age was associated with a rise in AT, PC, and PS plasma levels. No sex difference was found in AT plasma level. OCP-taking is associated with a decrease in AT and an increase in PC plasma levels. CONCLUSION: This is the largest study ever conducted on healthy individuals in the Iranian population, using specific reference interval results in accurate diagnosis of true AT, PC, and PS deficiency.

Prevalence and Costs of Complementary and Alternative Medicine among Traumatic Patients in Iran: A Nationwide Population-based Study.

BACKGROUND: This study was aimed to determine the prevalence, predictors and cost of CAM practitioner use among traumatic patients in Iran. METHODS: This cross-sectional household survey of a nationally representative sample of Iranians 15 to 64 yr old was conducted in 2011, using a three-stage cluster sampling. Short Form Injury Questionnaire 7 (SFIQ7) was utilized through face-to-face interviews and data on demographics, history of injuries, mechanism, site and type of injury, type and place of the treatment were attained. Via telephone calls, service use and costs of treatment were also collected. RESULTS: The prevalence of CAM practitioner use in injured people and victims seeking medical care was 0.7% and 4.1%, respectively in 3-month interval in 2011. There were no significant sociodemographic differences between victims who seek unconventional settings and those who seek conventional treatment. The most common injury description treated by CAM providers was as follows: fracture (type of injury), upper limb (site of injury), fall (mechanism of injury) and cast, splint, and physiotherapy (type of treatment). The average medical cost of CAM practitioner was US$14.7 while this amount in the conventional setting was US$195.5. CONCLUSION: Use of CAM is not very common among injured people in Iran. However, due to lack of formal training, CAM usage has possible side effects.

Bipolar features in major depressive disorder: Results from the Iranian mental health survey (IranMHS).

BACKGROUND: Past research suggests that individuals suffering from depressive disorders with bipolar features might have different clinical outcomes resembling bipolar disorders. The objectives of this study are to determine the prevalence of bipolar features among individuals meeting the criteria for 12-month major depressive disorder (MDD) in the Iranian population and to examine the demographic and clinical characteristics associated with these features. METHODS: Data were drawn from the Iranian Mental Health Survey (IranMHS), a representative household survey of the Iranian population aged 15-64 years. The study sample consisted of all individuals with a 12-month MDD (n = 1014) ascertained by the Composite International Diagnostic Interview (CIDI 2.1) without a lifetime history of bipolar I or II disorders. Mood Disorder Questionnaire (MDQ) was used to screen for the lifetime history of bipolar features among participants with MDD. RESULTS: Among participants meeting the 12-month MDD criteria, 22.1% (95% CI: 19.6-24.7) had a lifetime history of bipolar features. Compared with those without these features, participants with bipolar features had higher odds of endorsing suicidal ideations and suicide attempts, comorbid anxiety and substance use disorders, severe impairment, history of psychotic symptoms, some features of atypical depression and fewer depressive symptoms. Associations with comorbid anxiety disorders [Odds Ratio (OR) = 1.43; 95% confidence interval (CI): 1.00-2.03] and history of psychotic symptoms (OR = 2.63 95% CI: 1.81-3.81) persisted in multivariable models. LIMITATION: Relying on self-reports of lifetime bipolar symptoms which is open to recall bias, and cross-sectional study design which limits interpretation of outcome and course of MDD are two major limitations of this study. CONCLUSION: The presence of bipolar features is associated with a distinct demographic and clinical profile in MDD. Identifying these cases would enhance the homogeneity of the depressive disorder phenotype in general population surveys. Identifying MDD patients with these features has potential clinical implications.

Methods for calculation of per capita alcohol consumption in a Muslim majority country with a very low drinking level: Findings from the 2011 Iranian mental health survey.

INTRODUCTION AND AIMS: There is a paucity of data on volume of alcohol use from Muslim majority countries. We aimed to present estimation methods for alcohol consumption with the use of survey data for these societies and provide an estimation for age 15+ per capita consumption of pure alcohol for Iran. DESIGN AND METHODS: The Iranian Mental Health Survey was a nationally representative household survey on individuals aged 15-64 years, with a multistage, cluster sampling design. We used the 'Last Week' method and 'Quantity-Frequency' methods for gathering data on alcohol consumption and combined these to provide more complete estimates. RESULTS: The response rate was 85.7%. From the total of 7840 respondents, 5.7% and 1% reported past 12 months and past week alcohol use, respectively. The highest estimation for age 15+ per capita consumption of pure alcohol was yielded by the 'combination method' (0.108 L ethanol/person/year) followed by the Quantity-Frequency method (0.079 L). The 'Last Week' method provided the lowest estimate (0.059 L). DISCUSSION AND CONCLUSIONS: Unlike in surveys of non-Muslim countries, frequency of drinking from recent recall (last week) was much lower than from recall of usual drinking in the last year. We conclude that 0.108 L (SE = 0.03) is the best survey-based estimate of age 15+ per capita consumption, which translates to about 5 750 000 L of national consumption per year in Iran. However, this method is still likely to under-estimate per capita consumption due to evidence of under-reporting in the survey.

Adaptation and validation of short scales for assessment of psychological distress in Iran: The Persian K10 and K6.

OBJECTIVES: The aims of the study were to translate into Persian and culturally adapt the Kessler Psychological Distress Scales, K10 and K6, and to assess their reliability and validity. METHOD: The sample was recruited from primary health care (PHC) settings by quota nonprobability sampling, stratified by sex and age. Validity was assessed against the Composite International Diagnostic Interview (v2.1). The psychometric properties of K6 and K10 were also compared with the 12-item General Health Questionnaire (GHQ-12). RESULTS: A total of 818 participants completed the questionnaire. Cronbach's alpha were 0.92 and 0.87 for K6 and K10, respectively. Optimal cutoff scores for detecting any mood or anxiety disorder in the past 30 days were 15 for K10 and 10 for K6. At these cutoff points, the measures had sensitivities of 0.77 and 0.73, specificities of 0.74 and 0.78, and positive predictive values of 0.48 and 0.52, respectively. Psychometric properties of K10 and K6 were similar to GHQ-12. CONCLUSION: Persian K10 and K6 have acceptable psychometric properties as screening instruments for common mental health conditions. Given its brevity and similar psychometric properties to the longer instruments, the Persian K6 appears to be a suitable scale for use in PHC settings and, possibly, epidemiologic studies in Iran.

Psychiatric disorders among people living with HIV/AIDS in IRAN: Prevalence, severity, service utilization and unmet mental health needs.

BACKGROUND: HIV and psychiatric disorders are closely correlated and are accompanied by some similar risk factors. OBJECTIVE: The aim of this study was to assess psychiatric comorbidity and health service utilization for mental problems among people living with HIV/AIDS in Iran. METHODS: A total of 250 cases were randomly selected from a large referral center for HIV treatment and care in Tehran, Iran. Psychiatric disorders in the past 12 months including mood, anxiety, and substance use disorders were assessed through face-to-face interview, using a validated Persian translation of the Composite International Diagnostic Interview (CIDI v2.1). Severity of psychiatric disorders, social support, socio-economic status, service utilization and HIV-related indicators were assessed. RESULTS: Participants consisted of 147 men and 103 women. Psychiatric disorders were found in 50.2% (95% confidence interval: 43.8-56.6) of the participants. Major depressive disorder was the most prevalent diagnosis (32.1%), followed by substance use disorders (17.1%). In bivariate analysis, psychiatric disorders were significantly higher among male gender, single and unemployed individuals and those with lower social support. In multivariate regression analysis, only social support was independently associated with psychiatric disorders. Among those with a psychiatric diagnosis, 41.1% had used a health service for mental problems and 53% had received minimally adequate treatment. CONCLUSION: The findings of the study highlight the importance of mental health services in the treatment of people living with HIV/AIDS.

Depressive symptoms among metabolically healthy and unhealthy overweight/obese individuals: a comparative study.

Background: Although a growing body of evidence suggests an association between obesity and depressive disorder, the association remains inconclusive. Metabolically healthy obese (MHO) phenotype, defined by favorable lipid profile, and normal insulin sensitivity, blood pressure, may be considered as a possible explanation for these inconsistencies. Accordingly, this study aimed to compare depression score among metabolic unhealthy obese (MUO) and age- and sex-matched healthy controls. Methods: In this comparative study including 157 Iranian adults, we assigned participants into three groups (non-obese metabolic healthy group, MHO and MUO) according to the BMI cutoff and MetS criteria. Depressive symptoms were assessed by Beck Depression Inventory. Analysis was done using SPSS version 14.0. All variables are expressed as means ± SD. One-way ANOVA and multiple linear regression were used for data analysis. Results: After adjustment for sex, marital status and educational level, MUO participants had significantly higher Beck depression score (P= 0.036) compared to MHO and non-obese metabolic healthy groups. After adjustment for demographic variables, there was a significant association between waist circumference (ß = 0.142, p=0.023), BMI (ß= 0.347, p= 0.037), FBS (ß= 0.096, p< 0.001), and the number of MetS components (ß= 1.71, p= 0.002) with depression score. Conclusion: MHO was a benign phenotype in relation to depression.

Prevalence and Risk Factors of Human Intestinal Parasites in Roudehen, Tehran Province, Iran.

BACKGROUND: Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran. METHODS: In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014. The samples were examined by formalin-ether concentration, culture, and with molecular methods. RESULTS: The prevalence of enteric parasites was 32.7% (95% CI 27.3-38). Blastocystis sp. was the most common intestinal protozoan (28.4%; 95% CI 23.7-33.0). The formalin-ether concentration and culture methods detected Blastocystis sp., Entamoeba coli, Giardia intestinalis, Dientamoeba fragilis, Iodamoeba butschlii, Entamoeba complex cysts or trophozoite, Chilomastix mesnilii, and Enterobius vermicularis. Single-round PCR assay for Entamoeba complex were identified Entamoeba dispar and E. moshkovskii. E. histolytica was not observed in any specimen. Multivariate analysis showed a significant association of parasites with water source and close animal contact. There was no correlation between infections and gender, age, occupation, education, or travel history. Protozoan infections were more common than helminth infections. CONCLUSION: This study revealed a high prevalence of enteric protozoan parasite infection among citizens of Rodehen. As most of the species detected are transmitted through a water-resistant cyst, public and individual education on personal hygiene should be considered to reduce transmission of intestinal parasites in the population.

Technical efficiency of rural primary health care system for diabetes treatment in Iran: a stochastic frontier analysis.

BACKGROUND: Our aim was to explore the technical efficiency (TE) of the Iranian rural primary healthcare (PHC) system for diabetes treatment coverage rate using the stochastic frontier analysis (SFA) as well as to examine the strength and significance of the effect of human resources density on diabetes treatment. METHODS: In the SFA model diabetes treatment coverage rate, as a output, is a function of health system inputs (Behvarz worker density, physician density, and rural health center density) and non-health system inputs (urbanization rate, median age of population, and wealth index) as a set of covariates. Data about the rate of self-reported diabetes treatment coverage was obtained from the Non-Communicable Disease Surveillance Survey, data about health system inputs were collected from the health census database and data about non-health system inputs were collected from the census data and household survey. RESULTS: In 2008, rate of diabetes treatment coverage was 67% (95% CI: 63%-71%) nationally, and at the provincial level it varied from 44% to 81%. The TE score at the national level was 87.84%, with considerable variation across provinces (from 59.65% to 98.28%).Among health system and non-health system inputs, only the Behvarz density (per 1000 population)was significantly associated with diabetes treatment coverage (ß (95%CI): 0.50 (0.29-0.70),p < 0.001). CONCLUSION: Our findings show that although the rural PHC system can considered efficient in diabetes treatment at the national level, a wide variation exists in TE at the provincial level. Because the only variable that is predictor of TE is the Behvarz density, the PHC system may extend the diabetes treatment coverage by using this group of health care workers.

Out-of-pocket cost of drug abuse consequences: results from Iranian National Mental Health Survey.

Drug abuse has significant cost to the individual, the family and the society. This study aimed to assess out of-pocket costs of consequences of drug use disorder. Data were drawn from the Iranian Mental Health Survey (IranMHS) through face-to-face interviews with 7841 respondents aged 15-64 years. We used a bottom-up cost-ofillness method for economic analysis. Out-of-pocket costs for treatment of mental and drug problems, treatment of medical illnesses, as well as costs of crimes were assessed. The average of total annual expense was US$ 2120.6 for those with drug use disorder, which was 23.5% of annual income of an average Iranian family in the year 2011. The average of total out-of-pocket cost was US$ 674.6 for those with other mental disorder and US$ 421.9 for those with no mental disorder. Catastrophic payment was reported in 47.6% of the patients with drug use disorder and 14.4% of those with other mental disorder. Thus, considerable amount of family resources are spent on the consequences of drug use.

Alcohol use disorders in Iran: Prevalence, symptoms, correlates, and comorbidity.

BACKGROUND: For nearly four decades, alcohol production and consumption has been banned in the Islamic country of Iran. However, little is known about the extent of alcohol use and associated problems in the country. The paper aims to present findings on the 12-month prevalence, symptoms, severity, correlates, and comorbidity of alcohol use disorders in the Iranian population. METHODS: This report is based on the 2011 Iranian household Mental Health survey (IranMHS), a nationally representative face-to-face household survey with a multi-stage, cluster sampling design. A total of 7840 individuals aged 15-64 responded to the alcohol section. We assessed 12-month alcohol use disorders according to DSM-IV and DSM-5 criteria and harmful use according to the ICD-10 criteria. RESULTS: Weighted prevalence of using alcohol at least once in the past 12 months was 5.7%. The prevalence of 12-month alcohol use disorders was 1% according to DSM-IV criteria and 1.3% according to DSM-5. Harmful use was reported in 0.6%. Alcohol use disorders were markedly more common in men than women with an odds ratio (OR) of 13.3. It was also more prevalent in never-married versus married individuals (OR=2.5) and in those living in urban versus rural areas (OR=2.4). Among those with alcohol use disorders, 46.3% had a concurrent mood or anxiety disorder. Aggressive behaviors and injuries were more likely in those with alcohol use disorders. CONCLUSION: Although Iran has a low level of alcohol use, its adverse consequences including use disorders, aggression, and injuries are moderately common and raise serious public health concerns.

Explaining socioeconomic inequalities in illicit drug use disorders in Iran.

Background: Drug use disorders are one of the major health problems in societies, which cause physical, psychological, and social damages to individuals. Socioeconomic status is often inversely associated with drug use disorders. The present study aimed at determining the effect of socioeconomic inequality on the prevalence of drug use disorders and identifying its determinants in Iran. Methods: Data of 7886 individuals aged 15 to 64 years were collected from Iran Mental Health Survey (IranMHS). Initially, the socioeconomic status of the participants was determined by principal component analysis. Later, socioeconomic inequality was measured using the concentration index, and the factors influencing the gap between the high and low socioeconomic groups were identified using the Oaxaca-Blinder Decomposition. Results: The concentration index for drug use disorders in Iran was -0.29 (standard error= 0.06). The results of decomposition technique revealed that 1.14% and 2.7% of the participants with high and low socioeconomic status were affected by drug use disorders, respectively. In addition, the gap between these 2 groups was found to be 1.65%. Among the studied variables, occupation, marital status, and gender accounted for the highest contribution to inequality, respectively. Conclusion: There is inequality in the prevalence of drug use disorders in Iran; these disorders are more common in lower socioeconomic group. Based on the findings, it is suggested that improvement in the socioeconomic status of the households, especially for males, the divorced or widowed individuals, and the unemployed may lead to a reduction in inequality in drug use disorders.

Psychiatric Disorders Are Associated with an Increased Risk of Injuries: Data from the Iranian Mental Health Survey (IranMHS).

BACKGROUND: Injuries and psychiatric disorders, notably both major public health concerns, are associated with a high burden and are believed to be bi-directionally correlated. Those inflicted with injuries face increased risks of mental illnesses. Psychiatric disorders may make the individual prone to injuries. The objective of the study was to assess the correlation of mental disorders with non-fatal injuries. METHODS: A total of 7886 participants aged 15 to 64 yr were interviewed in a national household survey in 2011 in Iran. Composite International Diagnostic Interview (CIDI v2.1) was implemented to assess the prevalence of psychiatric disorders in the past twelve months. Injuries were assessed using Short Form Injury Questionnaire (SFIQ-7). RESULTS: Injury was reported in 35.9% and 22.8% of participants in the past twelve and past three months, respectively. Using multivariate logistic regression analysis, mental disorders were significantly associated with injuries in the past three months (OR=1.6, 95% CI:1.36-1.87), recurrent injuries (OR=1.7, 95% CI: 1.21-2.41) and road/traffic accidents (OR=2.4, 95% CI: 1.28-4.49). CONCLUSION: Psychiatric disorders were found to be associated with an increased risk of injuries. Early detection and treatment of mental illnesses can contribute to injury prevention.

Epidemiology of illicit drug use disorders in Iran: prevalence, correlates, comorbidity and service utilization results from the Iranian Mental Health Survey.

BACKGROUND AND AIMS: Drug abuse is a significant social and public health problem in Iran. The present study aimed to provide prevalence estimates and information on correlates of illicit drug use disorder and opioid dependence, as well as service use for these disorders in Iran. DESIGN, SETTING AND PARTICIPANTS: This report is based on the Iranian household Mental Health Survey (IranMHS) conducted in 2011. A three-stage probability sampling was employed. Face-to-face interviews by trained psychologists were carried out with a nationally representative sample of 7841 individuals (3366 men and 4475 women) aged 15-64 years. MEASUREMENTS: The Composite International Diagnostic Interview and questionnaires for socio-demographic correlates and service use. FINDINGS: The prevalence of 12-month use disorders for any illicit drug according to DSM-IV and DSM-5 criteria were 2.09% [95% confidence interval (CI) = 1.70-2.47%] and 2.44% (95% CI = 2.03-2.85%), respectively. Opioid use disorders, and opium in particular, were the most common use disorder. The odds of drug use disorders were greater in men than in women, in previously married participants than in currently or never married participants, and in participants with lower socio-economic status than in those with higher socio-economic status (all P-values <0.05). Approximately half of those with drug use disorders and 40% with opioid dependence had a 12-month unmet need for treatment. Self-help groups were the most common type of service used, followed by obtaining medication from pharmacies directly and outpatient treatment services. CONCLUSIONS: Opioid use disorders are the most common type of drug use disorders in Iran, setting Iran apart from many other countries. Patterns of service use suggest a large unmet need for drug use disorder treatment in Iran.

Assessing measurement error in surveys using latent class analysis: application to self-reported illicit drug use in data from the Iranian Mental Health Survey.

Latent class analysis (LCA) is a method of assessing and correcting measurement error in surveys. The local independence assumption in LCA assumes that indicators are independent from each other condition on the latent variable. Violation of this assumption leads to unreliable results. We explored this issue by using LCA to estimate the prevalence of illicit drug use in the Iranian Mental Health Survey. The following three indicators were included in the LCA models: five or more instances of using any illicit drug in the past 12 months (indicator A), any use of any illicit drug in the past 12 months (indicator B), and the self-perceived need of treatment services or having received treatment for a substance use disorder in the past 12 months (indicator C). Gender was also used in all LCA models as a grouping variable. One LCA model using indicators A and B, as well as 10 different LCA models using indicators A, B, and C, were fitted to the data. The three models that had the best fit to the data included the following correlations between indicators: (AC and AB), (AC), and (AC, BC, and AB). The estimated prevalence of illicit drug use based on these three models was 28.9%, 6.2% and 42.2%, respectively. None of these models completely controlled for violation of the local independence assumption. In order to perform unbiased estimations using the LCA approach, the factors violating the local independence assumption (behaviorally correlated error, bivocality, and latent heterogeneity) should be completely taken into account in all models using well-known methods.

Incidence of fall-related injuries in Iran: A population-based nationwide study.

BACKGROUND: Fall-related injuries are considered to be a leading cause of morbidity and disability worldwide. The aim of this study was to investigate the incidence of fall-related injuries and its determinants in Iran. METHODS: A cross-sectional household survey of a representative sample of 15-64 years old Iranians was carried out in 2011. A three-stage cluster sampling design was used. Total of 1525 clusters were randomly selected. Six households in each cluster were randomly selected, and one member of each household was interviewed. Data on the demographics and history of fall-related injury were obtained using the previously validated and reliability tested Short Form Injury Questionnaire 7 (SFIQ7). In all, 7886 subjects responded to the survey. RESULTS: The incidence rate of all fall-related injuries was 59 (95%CI: 45-72) per 1000 person-year. The incidence rate of First Aid Fall-Related Injuries (FAFRIs) and Medical Attended Fall-Related Injuries (MAFRIs) were 30±5 and 28±12, respectively. Homes were the most common place of falls (52.5%). For all and MAFRIs, the most common activity leading to fall injury was walking (37.8% and 47.6%, respectively) whereas for FAFRIs was playing (31.9%). For all and FAFRIs, the most common description was as follows: upper limb as the injured organ (52.0% and 61.2%, respectively) and superficial wound as the most prevalent type of injury (39.0% and 61.8%, respectively). However, for MAFRIs, lower limb injuries (52.9%) and fracture (43.6%) were more pronounced. Risk factors for MAFRI were as follows: paid work activity (OR: 3.11; 95%CI: 2.07-4.67), playing (OR: 14.64; 95%CI: 6.34-33.80), walking (OR: 57.09; 95%CI: 28.95-112.59), driving (OR: 2.86; 95%CI: 1.23-6.63), and recreation activities (OR: 44.11; 95%CI: 14.04-138.54). Higher age and education were the other risk factors for MAFRI, as well as residing in rural areas. CONCLUSION: This study revealed considerable incidence of fall injuries in Iranian population especially in rural regions who need access to protective equipment. People need to be warned about the constant risk of fall even during non-avoidable activities such as walking, playing, driving and paid/unpaid working especially in older ages. Implementation of fall prevention measures, home and behavioural modifications are recommended.

Preventive effect of Malva on urinary toxicity after radiation therapy in prostate cancer patients: A multi-centric, double-blind, randomized clinical trial.

BACKGROUND: For patients receiving external beam radiation therapy (EBRT) after radical prostatectomy as adjuvant treatment or patients receiving EBRT as definitive treatment, partial irradiation of the urinary bladder is common. Many of such patients experience some degree of radiation-induced cystitis during or after EBRT. There is currently no efficient treatment for preventing radiation cystitis. OBJECTIVE: The aim of this study was to evaluate the effectiveness of one of the safe mucilaginous herbs (Malva) in preventing radiation-induced dysuria in patients who are undergoing EBRT for prostate cancer. METHODS: From April 2013 to August 2014, 68 patients were randomized into two groups using four block randomization, 34 to the drug (Malva) group and 34 to the placebo group. Of the 68 patients who began the study, 60 completed it. They were instructed to use the medication, i.e., Malva or the placebo, three times a day for six weeks. They were followed by a physician every two weeks for eight weeks, and urinary function was assessed in each visit by asking questions based on the Visual Prostate Symptom Score (VPSS) and a dysuria severity score. The changes in the VPSS and dysuria severity score between baseline and each follow-up visit were compared between the two groups in the study using repeated measures analysis of variance (ANOVA) and t-tests. RESULTS: The median age of the 68 patients was 66. Twenty-one of 27 patients in the control group (77.7%) suffered from dysuria, while dysuria was detected in 23 of 33 patients (69.6%) who received Malva (odds ratio=2.70 for dysuria). After two weeks, four weeks, and six weeks of treatment with Malva, dysuria due to EBRT was milder in the treatment group than in the control group, and the differences were statistically significant (p = 0.005, p = 0.004, p = 0.001, respectively). CONCLUSION: To the best of our knowledge, our study is the first study to assess the protective effect of a mucilaginous herb (Malva) against urinary toxicity induced by EBRT. The positive results of this study warrant further studies in this field.

Population-based incidence and cost of non-fatal injuries in Iran: a consistent under-recognized public health concern.

OBJECTIVES: To investigate the incidence and determinants of non-fatal injuries, and the cost imposed on victims in an Iranian population aged 15-64 years. DESIGN: Cross-sectional household survey. METHODS: Three-stage probability sampling was conducted for selection of a representative sample of Iranians. Data on the demographics, history and cost of injury were obtained from face-to-face interviews and telephone calls. RESULTS: In total, 7886 subjects were included in this study. The annual incidence rate of all injuries was 905 (95% confidence interval 853-957) per 1000 population (approximately nine injuries per ten Iranians). The mean (±standard error) incidence rates of first aid injuries (FAIs; medical care not required) and medical-attended injuries (MAIs; medical treatment sought) were 737 ± 24 and 168 ± 12 per 1000 population, respectively. Young, urban females were at highest risk for FAIs, and single males were at highest risk for MAIs. The most common injury description was as follows: non-paid work (activity), home (place), inanimate mechanical force (mechanism), upper limb (site of injury) and open wound (type of injury). For MAIs, the most common place of treatment was hospital. Traffic-related injuries had the highest total cost and the lowest out-of-pocket cost. Total and out-of-pocket costs of non-fatal injuries in Iran in 2011 have been estimated to be US$6,111,138,000 and US$1,480,411,000, respectively. CONCLUSION: Non-fatal injuries are an under-recognized public health problem. Cost-control policies are essential to reduce the out-of-pocket cost of injuries.
