Decomposition of Healthcare Utilization Inequality in Iran: The Prominent Role of Health Literacy and Neighborhood Characteristics.

Unequal utilization in healthcare can potentially affect the right to health. Access to healthcare services and achieving positive health outcomes and health equity are essential principles in promoting human rights. This study aims to assess and analyze socioeconomic-related inequalities in outpatient health services utilization (OHSU) among various socio-demographic subgroups to inform policies that foster health equity. Data were collected through a cross-sectional survey of 1200 households in Tehran, Iran. Inequality in OHSU among the socio-demographic subgroups was calculated by concentration, Wagstaff, and Erigers indices. Decomposition was used to identify the factors contributing to inequality in OHSU. Marginal effect and elasticity were used to calculate the relative absolute shares of socio-demographic variables in the inequality. The rate of OHSU was 63.61% (CI: 60-66.80) which concentrated among households with better socioeconomic status. Based on the results, living in an affluent neighborhood (Relative share (RS): 85.48) and having a disabled member in the household (RS: 6.58) were the most important factors in the concentration of OHSU in favor of the privileged groups. In contrast, very low levels of health knowledge (RS: -83.79) and having basic insurance coverage (RS: -3.92) concentrated OHSU in favor of the lower socioeconomic households. The study was conducted based on survey data, and this may lead to some limitations. Given that this study was a cross-sectional study, we were unable to establish causal relationships between explanatory variables and outpatient health service utilization and its relevant predictors. Households with disabled member(s), as well as a member(s) with chronic diseases, may experience severe inequalities in access to healthcare services. Policies that facilitate access to health services for these households can play a significant role in improving health equity.

The influence of home and environmental characteristics on 5-18 years old children's health during the COVID-19 pandemic: A cross-sectional study in Iran.

Background: The coronavirus disease (COVID-19) pandemic has dramatically changed the health and wellbeing of children. Therefore, this study aimed to investigate the relationship between the home environment and the environmental characteristics on 5-18 years old children health in Iran. Method: An online survey was conducted among parents of children aged 5 to 18 living in large cities in Iran in 2021. The statistical population of this cross-sectional study was 500 people. In this survey, questionnaires on the quality of the home environment, exterior and interior landscapes of homes, and the Child Health Questionnaire (CHQ) were used to investigate the relationship between the home environment and environmental characteristics on 5-18 years old children health during the COVID-19 pandemic. The t-test and analysis of variance were used in SPSS 24, and the structural equation modeling (SEM) was utilized in AMOS 24 for analyzing the data. Results: The average age of respondents was 37.13 ± 7.20, and that of children was 11.57 ± 3.47. 73.02% of the families were covered by insurance, and 74.08% of them lived in the metropolis. In addition, 65.04% of the families complied with the restrictions of the quarantine period. A share of 31% of the families live in villas, and 55% paid more attention to cleaning their homes during the COVID-19 pandemic than before. A positive and significant statistical relationship (ß = 0.414, p < 0.001) was observed between the residence environment and child health. Thus, explained 17.5% of variations in child health. Conclusion: The results showed that the children who lived in homes with an exterior landscape in nature had better health. In addition, the 5-18 years old children whose home landscape was a garden, compared to the other two groups (yard, balcony), had better health. Gardens are a potential source of health and not necessarily replaced by other natural environments, thus providing them along with green space is one of the crucial issues that should be considered.

Effect of Social Support Interventions on Adherence to Antiretroviral Therapy Among People Living with HIV: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis examined the effects of social support interventions (SSIs) on adherence to antiretroviral therapy (ART) among people living with HIV. We systematically searched Web of Science, PubMed/MEDLINE, Scopus, and Cochrane Library in September 9, 2020. English-language publications of randomized controlled trials (RCTs) in peer-reviewed journals were considered eligible. To estimate the effects of SSIs on adherence to ART, odds ratios (ORs) with 95% confidence intervals (CIs) were pooled using random effects models. Subgroup analysis was used to investigate the sources of heterogeneity. Of 243 records identified, 17 controlled trials were included. The meta-analysis found significant and moderate effect size in the improvement of adherence to ART from SSIs. Subgroup analysis showed that the study design, follow up duration, source of social support, and year of publication significantly moderated the effect sizes in the meta-analysis. Our findings support the hypothesis that social support interventions can improve adherence to ART. Using various types and sources of social support, further research is needed to assess the effect of SSIs on adherence to ART across different settings.

Climate Change and Respiratory Diseases: Relationship between SARS and Climatic Parameters and Impact of Climate Change on the Geographical Distribution of SARS in Iran.

Climate change affects human health, and severe acute respiratory syndrome (SARS) incidence is one of the health impacts of climate change. This study is a retrospective cohort study. Data have been collected from the Iranian Ministry of Health and Medical Education between 17 February 2016 and17 February 2018. The Neural Network Model has been used to predict SARS infection. Based on the results of the multivariate Poisson regression and the analysis of the coexistence of the variables, the minimum daily temperature was positively associated with the risk of SARS in men and women. The risk of SARS has increased in women and men with increasing daily rainfall. According to the result, by changes in bioclimatic parameters, the number of SARS patients will be increased in cities of Iran. Our study has shown a significant relationship between SARS and the climatic variables by the type of climate and gender. The estimates suggest that hospital admissions for climate-related respiratory diseases in Iran will increase by 36% from 2020 to 2050. This study demonstrates one of the health impacts of climate change. Policymakers can control the risks of climate change by mitigation and adaptation strategists.

Disaster Risk Reduction in Iranian Primary and Secondary School Textbooks: A Content Analysis.

OBJECTIVE: School textbooks have a significant role in transferring knowledge to the students and changing their behavior. This work aims to analyze school textbooks to find the representation of natural hazards in Iran, which is vital for supporting children in disaster situations. METHODS: In this study, a qualitative content analysis was used. Data were analyzed qualitatively by using MAXQDA 2018 software. For the 2019-2020 school year, 300 Iranian school textbooks in Persian language were collected. RESULTS: Findings of this work show that students receive information about disaster risk reduction (DRR) education through the primary and secondary grade levels in all 12 grades. The educational content covers various types of natural hazards, including geophysical, hydrological, climatological, meteorological, and biological disasters. In addition, the textbooks contain discussions about local hazards, causes and effects of disasters, and the disaster management cycle. CONCLUSIONS: The coverage of DRR and the relevant contents in school textbooks reveals that the discourse of natural hazards is important for Iranian authorities, especially in the education system. This study helps decision-makers and practitioners design more effective interventions to prepare children for disasters.

Validation of the Persian version of the mental health literacy scale in Iran.

The present study was designed to validate an English version of the mental health literacy scale into Persian, in Iran. Statistical population consisted of all residents of 22 municipal districts of Tehran, Iran, in 2018. Multistage sampling methods were used (sample size = 1026). All participants filled the Mental Health Literacy scale; 12-item General Health Questionnaire; Multidimensional Health Locus of Control scale and a demographic checklist. Exploratory and confirmatory factor analysis, the intra-class correlation coefficient was used for analysing data. All analyses were run with SPSS and AMOS Graphics version 18. Exploratory factor analysis revealed five components (24 items) explaining 21.68%, 20.24%, 8.97%, 6.48% and 5.36% of the variance respectively (totally explained variance = 62.74%). Confirmatory factor analysis showed an acceptable goodness-of-fit (CMIN/DF = 3.19, GFI = 0.887, CFI = 0.893, IFI = 0.894, TLI = 0.877, RMSEA = 0.065). The values of Cronbach's alpha showed satisfactory internal consistency. Two clinical correlates of mental health literacy were investigated. The structure of the mental health literacy scale was to some extent different from the one in O'Connor et al. study, but it was consistent with the definition of MHL presented by Jorm et al. This is the first Persian version of the MHL in the general population in Iran and undoubtedly needs to be checked on more studies.

School-Based Education Programs for Preparing Children for Natural Hazards: A Systematic Review.

Schools have a significant role in disaster education to children. This study investigates the research works about school-based education programs in order to discover challenges and best practices. We conducted a systematic review of English language papers published in peer-review journals.The search identified 2577 publications and 61 articles meeting selection criteria and included in the review. Reviewed studies indicated that disaster education in schools is effective but yet insufficient in many countries. Lack of equipment, financial resources, policy gaps, and teachers' knowledge are common problems in programs. Main outcomes of this systematic review are showing methods used for health emergency preparedness of children of different ages and gender differences in school-based disaster preparedness, as well as the difference in their lifesaving skills in disasters.This study shows that some disaster education programs reported in the papers reviewed were not high-quality enough, which may lead to insufficient preparedness of children in disasters and consequently may put their health at risk, considering the increasing number of natural hazards.

Social Support Associated with Condom Use Behavior Among Female Sex Workers in Iran.

BACKGROUND: Despite the widespread knowledge about social support and health, there is little information about the association between social support and HIV risk behaviors such as condom use among female sex workers (FSWs) in Iran. This study aimed to determine the association between social support and frequency of condom use among FSWs in Tehran, Iran. METHODS: Using mixed sampling methods, we recruited 170 FSWs in Tehran in 2017. We measured self-reported social support by face-to-face interviews using a standardized questionnaire. Linear regression was used to assess the association between socio-demographic characteristics (age, education level, marital status, and place of living), transactional sex characteristics (age at first transactional sex and frequency of transactional sex in the last month), HIV knowledge, social support network characteristics (social network size, duration of tie, intimacy, social support), and condom use behavior. RESULTS: Of the total of 1193 persons in FSW's social networks, 615 (51%) were sexual partners, 529 (44%) were peer sex workers, and 36 (5%) were family members. The participants perceived moderate social support from sexual partners, low from peer sex workers, and very low from family members. Adjusted for individual and other network characteristics, peer sex worker social support (b = 0.28, 95%CI 0.06, 0.50), and family support (b = 1.12, 95%CI 0.028, 2.23) were significantly associated with condom use. CONCLUSION: Family and peer sex worker social support are associated with condom use, but less strongly than HIV knowledge or place of living. However, very few FSWs are socially connected with families. Interventions to promote condom use among this vulnerable population should also consider social and familial support.

Trend and pattern of using herbal medicines among people who are aware of their diabetes mellitus: results from National STEPs Surveys in 2005 to 2011 in Iran.

OBJECTIVES: Use of traditional herbal medicines especially by those affected by chronic diseases, such as diabetes mellitus is important. The objective of this study was to assess trend and Pattern of using traditional herbal medicines by diabetic population in Iran. METHODS: The results of this study are extracted from the National Stepwise approach to chronic disease risk factor surveillance (STEPs), conducted in 2005- 2016 in Iran. A total of 3095 Iranian diabetic individuals, aged more than 25 years in 2005, 1470 diabetics in 2006, 1633 diabetics in 2007, 1652 diabetics in 2008, 1563 diabetics in 2009, and 1005 diabetics in 2011 were included in this study. We couldn't use data in 2016 because in 2016, traditional herbal use has not been questioned. First, a descriptive analysis of the study variables and prevalence of herbal use for each year, was performed. Thereafter, to determine which variables were independent predictors of adherence to herbal use, we performed multivariate logistic regression. RESULTS: Using traditional herbal medicines among Iranian adult population was increased from 11.1 (9.98-12.20) in 2005 to 23.5 (20.87-26.25) in 2011. The results show increase in herbal medicine use in all age groups, both urban and rural areas, and both male and female over time. Also, we found that using traditional herbal medicines was more common among female compared with male (24.2% versus 21.8%), older than middle-aged people (24.4% versus 15.9%), and people living in urban areas compared with rural area (24.13% versus 20.95%) in 2011. CONCLUSION: The use of traditional herbs for treatment, alone or in combination with other therapies by the patients who have diabetes has increased over the time. Considering the high level of using traditional herbal medicines in treatment of diabetes and because of the possible herb-drug interactions, policymakers need to take appropriate interventions to control herb store and increase people's knowledge about the herbal usage.

Determinants of safe sexual behavior of female sex workers in Tehran: the woman, her network, and the sexual partner.

BACKGROUND: Despite the steady growth of sexual transmission of HIV, there is little evidence about safe sexual behavior of FSWs, and social network effects on this behavior, in Iran. Our aim in this study was to determine the effect of social network characteristics on condom use among FSWs, considering individual characteristics of the FSWs and of their sexual partners, characteristics of their relationship, and the FSW's personal network. METHODS: A cross-sectional ego-centric network survey of 170 FSWs was carried out in Tehran between January and June 2017. A multilevel ordered logistic regression analysis was conducted to examine the effects of individual and relational characteristics simultaneously. RESULTS: Condom use in sexual relationships of the FSWs on average was rather low. Important determinants of safe sexual behavior were found both at the level of the individual FSW and at the level of the sexual partner. The main determinants at the level of the individual FSW were FSWs' age and HIV knowledge. At the level of the sexual partner, age and education of sexual partners, as well as intimacy, duration of tie, frequency of contacts with a given partner, frequency of contact, perceived social support, and perceived safe sex norms were significantly associated with condom use. CONCLUSIONS: The findings highlighted that considering only the individual characteristics of female sex workers is not sufficient for effectively promoting condom use. Factors at the network and dyadic level should also be considered, especially the role of sexual partners. Network-based interventions may be useful which modify social relationships to create a social environment that can facilitate changes in sexual behavior.

Outpatient health service utilization and associated factors: A cross-sectional population-based study in Tehran in 2019.

Background: Health service utilization (HSU) is a significant health and political issue. Awareness of factors that affect HSU and the status of health service utilization can help health professionals improve their services. The aim of this study was to investigate the status of HSU and identify the factors affecting health service utilization among households residing in Tehran. Methods: The present cross-sectional study included 1200 residing households from different regions of Tehran, the capital of Iran. They were selected by a multi-stage cluster sampling method in accordance with the zoning of Tehran concerning socio-economic development. Interviews were conducted by trained individuals using a health service utilization questionnaire introduced by the World Health Organization, Zimet's social support questionnaire, and demographic checklist during winter 2018 and spring 2019. Simple and multiple logistic regression models were applied to analyze the data. In order to include the factors related to the status of outpatient health service utilization, a set of bivariate analyses was conducted, and then the factors with a p-value of ≤0.20 were included in the multiple models. Data were analyzed using Stata 12 software. Results: The results of the study indicated that the rate of outpatient HSU among households residing in Tehran was 63.61% (CI:60, 66.80). In addition, regarding the results of the study, asset index of family (OR=0.51, 95% CI: 0.28, 0.91), the level of awareness and knowledge of family members regarding health issues (OR=0.55, 95% CI: 0.34, 0.88) as well as the mother knowledge on health issues (OR=0.64, 95% CI: 0.45, 0.93), the level of social support (OR = 0.50, 95% CI: 0.37,0.68), family health expenditure (OR=1.20, 95% CI: 1.18, 4.06), having a member with a sort of disability in family (OR=1.66, 95% CI: 1.01, 2.77), and having an alcoholic member in family (OR=2.44, 95% CI: 1.27, 4.68) were factors associated with outpatient HSU among households. Considering the adjusted values of odds ratios, the prevalence of the HSU varied according to the area of residence. It should be noted that the variables included in the model explained 15% of the changes in the prevalence of HSU. Conclusion: According to the results of the study and in order to increase HSU in different classes, the level of social support, especially among women in the family due to their role in the general health of family members, should be enhanced. Also, policies should be adopted to increase the awareness, knowledge, and information of family members about health issues, lifestyle changes, nutrition, and health behaviors through social media.

Determinants of mammography screening in Tehranian women in 2018 based on the health belief model: A cross-sectional study.

BACKGROUND: Breast cancer is the most common type of cancer among women. Mammography is the most sensitive and important method for screening and early diagnosis of breast cancer. Considering the importance of using mammography in breast cancer screening, this study was performed to evaluate mammographic determinants. MATERIALS AND METHODS: In the cross-sectional study, we surveyed 985 women over 40 years in Tehran concerning demographic characteristics: age, socioeconomic status, a problem in the breast, alcohol use, drug use, and health belief model. Logistic regression was used to identify determinant factors associated with mammography performance. RESULTS: The results of this study showed that 42.1% (95% confidence interval [CI]: 38, 45) participant performed mammography at least once during their lifetime. Age (odds ratio [OR] = 4.252; 95% CI = 2.041-8.857); housing situation (OR = 1.706; 95% CI = 1.178-2.469); having breast problems (OR = 5.224; 95% CI = 3.501-7.795); socioeconomic status (OR = 1.855; 95% CI = 1.035-3.325); family income level (OR = 1.998; 95% CI = 1.028-3.884); alcohol consumption (OR = 2.676; 95% CI = 1.344-5.328); smoking (OR = 2.824; 95% CI = 1.418-5.623); self-efficacy (OR = 1.935; 95% CI = 1.242-3.015); perceived barriers (OR = 2.017; 95% CI = 1.348-3.019); self-care (OR = 4.901; 95% CI = 3.152-7.620); perceived susceptibility (OR = 1.971; 95% CI = 1.271-3.057) and perceived severity (OR = 1.830; 95% CI = 1.170-2.860) were mammography behaviors determinants. CONCLUSION: The findings indicated that the rate of mammography screening among Tehranian women is low and highlights the need for developing a comprehensive national breast cancer control program, which should be considered as the priority for health-care providers. Furthermore, the identification of these factors can help to design an appropriate educational intervention that focuses on the benefits of mammography screening.

Child labor in Tehran, Iran: Abuses experienced in work environments.

BACKGROUND: Child labor is exploitative and harmful and deprives children of opportunities for a healthy life. Nonetheless, child labor is prevalent worldwide. Abusive working conditions are common, especially in developing countries. OBJECTIVE: This study was designed both to measure the prevalence of abuse in work environments and to identify possible risk and protective factors for such abuse in child laborers in Tehran, Iran. METHOD: The researchers conducted this cross-sectional study from September 2018 to May 2019 in Tehran and recruited 250 children from seven child labor support centers. RESULTS: The results demonstrated a relatively high rate of abuses experienced in work environments among Iranian child laborers: 77.6 % of children experienced at least one type of abuse, with emotional abuse (70.4 %) as the most frequently experienced abuse followed by neglect (52 %), physical abuse (5.8 %), and sexual abuse (3.6 %). Furthermore, living alone or with a single parent (OR = 3.15, CI 95 %: 1.33-7.45) was a risk factor, while working in home jobs (OR = 2.08, CI 95 %: 1.19-3.63), being male (OR = 0.19, CI 95 %: 0.06-0.55), and being older (OR = 0.32, CI 95 %: 0.17-0.60) were the protective factors of abuses experienced at work among child laborers. CONCLUSION: The findings of this study have implications for designing and implementing early interventions to provide less harmful work environments for child laborers. Further, advocacy efforts to prevent and eliminate child labor should be pursued.

Health services coverage: Physical access to rehabilitation facilities in Tehran compare with the country.

OBJECTIVE: According to the World Health Organization, estimates about 1,800,000 people lived with disability in Tehran. Against there is little evidence of physical access to rehabilitation facilities in Tehran. This study is aimed to assess the physical access to physical rehabilitation facilities in Tehran and compare it with the country. METHODS: This is a cross-sectional study conducted since January to April 2017. We used a master facilities list of rehabilitation facility that developed in Iran to collect the information. The samples of this study included all existing physical rehabilitation centers in Tehran province. Data analysis was done using the SPSSr version 21.0 (SPSS Inc., Chicago, IL). RESULTS: The results showed that rehabilitation facilities existed at different levels, including inpatient (10.51), outpatient (224.28), community based (36.72), and long-term care (4.96)/1,000,000 populations. Rehabilitation services are provided by rehabilitation professional including: Physical medicine and rehabilitation specialists (8.7), physiotherapists (132.89), occupational therapists (57.4), speech therapists (42.11), and audiologists (48.84) (in 1,000,000 populations). CONCLUSION: Tehran needs to increase the physical access to rehabilitation facilities and compared with country was disproportionate physical access to facilities in most cases. It is necessary to establish an interdisciplinary referral system between different rehabilitation providers.

Students' preparedness for disasters in schools: a systematic review protocol.

INTRODUCTION: Children are one of the most vulnerable groups in disasters. Improving students' knowledge and skills to prepare for disasters can play a major role in children's health. School as a place to teach children can make a significant contribution to provide the necessary skills. This study aims to identify the effects, strengths and weaknesses of interventions in schools to prepare children for disasters. METHODS AND ANALYSIS: We use Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to develop a protocol for this systematic review. The included studies will report on the results of interventions targeting 'schoolchildren' defined as individuals between 4 and under 18 years old studying in schools. Different electronic databases will be used for a comprehensive literature search, including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials and EMBASE to identify the records that match the mentioned inclusion criteria published till December 2020. The main search terms are 'disaster', 'preparedness', 'children' and 'school'. Four types of data will be extracted from the qualified studies including study characteristics (study design, year of publication and geographical region where the study was conducted), participant characteristics (sample size, age and gender), intervention characteristics (aim of intervention, intervention facilitators and barriers) and intervention outcomes. The quality appraisal of the selected papers will be conducted using Cochrane Collaboration's Risk of Bias for quantitative studies and Critical Appraisal Skills Programme checklist for qualitative studies. We use a narrative synthesis for this systematic review. The narrative synthesis refers to an approach to systematic reviews which focuses mostly on applying words and texts to summarise and explain findings. ETHICS AND DISSEMINATION: This paper is a part of a Ph.D. thesis of Hamed Seddighi at University of Social welfare and Rehabilitation Sciences with ethics code IR.USWR.REC.1399.008 approved by the Ethics Committee of the above-mentioned university. PROSPERO REGISTRATION NUMBER: CRD42020146536.

Determinants of Outpatient Health Service Utilization according to Andersen's Behavioral Model: A Systematic Scoping Review.

BACKGROUND: The present review focuses on identifying factors contributing to health service utilization (HSU) among the general adult population according to Anderson's behavioral model. METHODS: Published articles in English on factors related to HSU were identified by systematically probing the Web of Science, MEDLINE (via PubMed research engine), and Scopus databases between January 2008 and July 2018, in accordance with the PRISMA guidelines. The search terms related to HSU were combined with terms for determinants by Boolean operators AND and OR. The database search yielded 2530 papers. Furthermore, we could find 13 additional studies following a manual search we carried out on the relevant reference lists. RESULTS: Thirty-seven eligible studies were included in this review, and the determinants of HSU were categorized as predisposing, enabling, and need factors according to Andersen's model of HSU. The results demonstrated that all predisposing, enabling, and need factors influence HSU. In most studies, the female gender, being married, older age, and being unemployed were positively correlated with increased HSU. However, evidence was found regarding the associations between education levels, regions of residence, and HSU. Several studies reported that a higher education level was related to HSU. Higher incomes and being insured, also, significantly increased the likelihood of HSU. CONCLUSION: This review has identified the importance of predisposing, enabling, and need factors, which influence outpatient HSU. The prediction of prospective demands is a major component of planning in health services since, through this measure, we make sure that the existing resources are provided in the most efficient and effective way.

Preparing children for climate-related disasters.

Climate-related disasters affect different dimensions of children's health and well-being both directly and indirectly. Reducing children's vulnerability and exposure to climate-related disasters is crucial to protect them against risks. Children as climate-change agents and future leaders at local, national and international level can obviously contribute to reduce vulnerabilities in families and communities and transfer knowledge to them. Moreover, children can advocate for climate change mitigation. In the long term, participation of children in the climate change mitigation programmes may lead to fewer disasters and, consequently, less risk to their health. As government policies have failed to fully address and respond to the drivers of climate-related disasters, disasters preparedness and education for children should be considered an essential activity to protect children from disaster's risks. Main factors in shaping children's behaviour and response to disaster are increasing the risk perception and knowledge of the children. When a child perceived likelihood, susceptibility and severity of a disaster (such as earthquake), then they would be able and willing to learn how to prepare for that. So far, disaster education programmes for children have mostly relied on offline school-based training. Different innovative approaches can be applied to continue education within online and digital formats including virtual reality, digital games and online platforms. However, an advocacy support by influential entities such as companies engaged in entertainment industry is required to raise the awareness of public and particularly the children about disaster preparedness.

Income-Related Inequality in Traffic Accident Health Outcomes (Injury, Disability and Mortality): Evidence from the Nationwide Survey in Iran.

BACKGROUND: Despite many efforts, Iran continues to have a high rate of traffic accidents and poor health outcomes. This study aimed to measure income-related inequality for traffic accident health outcomes in Iran, a country with one of the highest rates of traffic accidents and related health problems. METHODS: The source of data was a national representative survey named the Iranian Multiple Indicator Demographic and Health Survey (IrMIDHS, 2010). Monthly household income is obtained through self-report in different quarters. Disparity rate ratio (DRR), slop index of inequality (SII) and the population attributable risk percentage measure (PAR%) were calculated. The concentration index (CI) of RTIs was used as our measure of socioeconomic inequality and decomposed into its determining factors. RESULTS: Using the DRR index, in the lowest income group, the risk of death from an accident was 2.3 times, greater and the risk of accidental disability was 11.7 times greater than for the third income quartet. The slope index also shows that the rate of road traffic deaths, disability and injury per 100,000 individuals decreased by 28, 82, and 392 moving from lower to higher incomes. This decrease in injury was about 581 for motorcyclists. CI was -0.04078643 (SE=.01424828, P-value 0.004). Male sex (68.9%), 15-29 yr old age (9.4%), employed activity status (20.8%) has a positive contribution in the RTIs concentration index. CONCLUSION: In addition to intervention related to the road safety and vehicles and reducing human errors, prevention of the road traffic ill health outcomes requires attention to reduction of inequality in society.

Contextual and Individual Determinants of Mental Health: A Cross-sectional Multilevel Study in Tehran, Iran.

OBJECTIVES: Our aim was to answer the following questions: (1) Can mental health variance be partitioned to individual and higher levels (e.g., neighborhood and district); (2) How much (as a percentage) do individual-level determinants explain the variability of mental health at the individual-level; and (3) How much do determinants at the neighborhood- or district-level explain the variability of mental health at the neighborhood- or district-level? METHODS: We used raw data from the second round of the Urban Health Equity Assessment and Response Tool in Tehran (in 2012-2013, n=34 700 samples nested in 368 neighborhoods nested in 22 districts) and the results of the official report of Tehran's Center of Studies and Planning (in 2012-2013, n=22 districts). Multilevel linear regression models were used to answer the study questions. RESULTS: Approximately 40% of Tehran residents provided responses suggestive of having mental health disorders (30-52%). According to estimates of residual variance, 7% of mental health variance was determined to be at the neighborhood-level and 93% at the individual-level. Approximately 21% of mental health variance at the individual-level and 49% of the remaining mental health variance at the neighborhood-level were determined by determinants at the individual-level and neighborhood-level, respectively. CONCLUSIONS: If we want to make the most effective decisions about the determinants of mental health, in addition to considering the therapeutic perspective, we should have a systemic or contextual view of the determinants of mental health.

Explanatory Model of Voluntary Childlessness among Iranian Couples in Tehran: A Grounded Theory Approach.

BACKGROUND: Global and Iranian statistics indicate a rise in the newly emerging phenomenon of voluntary childlessness as a permanent status among couples. Childlessness is one of the main challenges of modern society. In Iran, studies on the process of voluntary permanent childlessness are scarce. The present study aimed to investigate the causes and underlying factors of voluntary childlessness and to provide an explanatory model of this phenomenon among Iranian couples. METHODS: The present qualitative study was conducted using the grounded theory approach proposed by Strauss and Corbin. Married couples from Tehran (Iran) with no infertility problems who chose to be permanently childless were invited to take part in this research. Theoretical saturation was reached after 33 semi-structured in-depth interviews. RESULTS: Based on the results, the causal conditions of childlessness included the high-risk society and adverse experiences. Contextual and intervening conditions included social problems, social support, transitional society, natural resources, social presence of women, and marriage age. The strategies and interactions observed in childless couples included the suppression of feelings, conflicts, rationality, and malingering. The core phenomenon was individualism. CONCLUSION: Increased social problems and reduced social support endanger a society in transition toward modernity. Individualists resort to permanent childlessness by suppressing parental feelings, overcoming doubts about childbearing, and becoming nonchalant by running away from child-rearing responsibilities. Such people may resort to child adoption or to have pets in order to cope with loneliness.
