RESUMO
Background: Apnea disorder is influenced by social and environmental factors. By assessing its hot spots and geography, the foci of this disorder and its at-risk groups can be identified for health interventions. This study was conducted to investigate the spatial pattern of apnea disorder using GIS in the Kermanshah metropolis. Methods: In cross-sectional study was conducted in kermanshah, the statistical population were 119 people (73.95% male and 26.05% female) of Kermanshah residents, which referred to the sleep center from 2012 to 2018 due to apnea disorder. Information was collected from the records of patients referred to the Sleep Disorder Center of Farabi Hospital, which is the only service center in the west part of Iran. The statistical tests were the mean center, standard distance, Getis-Ord Gi * index, nearest neighbor index, and kernel density estimation test in GIS software. Results: The spatial pattern of patients with apnea disorder has cluster formation in the Kermanshah metropolis. The age group of 50-54 had more apnea disorder than other age groups. In this age group, women were more prone to apnea than men. In terms of education, people with high education are more affected by this disorder; So that with the increase in education level, apnea disorder had also increased. Also, the findings showed that the disorder was more common in unemployed, married, overweight people with BMI (25-30), and obese people (30-40). Conclusion: The spatial pattern of patients with apnea disorder was clustered and does not correspond to the high population density centers located in the marginal and slum areas of the city. These can be used by stakeholders, including governmental organizations and health authorities at the national-regional level.
RESUMO
There is limited research on the role of lifestyle in people living with HIV (PLWH). This study investigated the health-promoting lifestyle among PLWH in Kermanshah-Iran. This cross-sectional study was conducted in 321 PLWH patients referred to the Kermanshah Behavioral Diseases counseling Center between 2017 and 2018. Patients were selected using the convenience sampling method. Data was collected using a standard health promotion lifestyle profile (HPLP-II) questionnaire. Regression and T-tests were used in SPSS 21 and Stata software to analyze the data. The mean age of patients was 41.07 ± 9.14 years. The mean HPLP score of patients in stress management had the lowest mean score (19.44 ± 4.22), and health responsibility had the highest mean score (22.22 ± 4.57). Comparisons between women and men also showed that women had a lower mean score than men in stress management. In addition, significant differences in their HPLP were observed only in the area of physical activity. The final model had significant influence on the PLWH (P < .001), in which the main predictors were housing status, family members, and feelings of happiness. These variables had a negative effect on HPLP in PLWH's. An appropriate education and training has improved the PLWH health-oriented lifestyle. Given that the housing situation affected health responsibility, nutrition, spiritual growth, interpersonal relationships, and stress management, may have caused severe anxiety and confusion in PLWH. Addiction also had a negative effect on patients' spiritual growth. Relatively simple lifestyle changes such as nutrition and stress management can significantly improve PLWH.

OBJECTIVES: This study investigated preventive behaviors toward coronavirus disease 2019 (COVID-19) and related factors in a Kurdish Iranian sample. METHODS: This online survey was conducted among the population aged 18 and above in Kermanshah Province, in western Iran, in April 2020. Samples were invited and recruited through social media. Data were collected using a questionnaire consisting of 4 sections (questions on demographic variables, risk perception, risk communication, and COVID-19 preventive behaviors) and analyzed using Stata ver. 8. RESULTS: The Pearson correlation test showed that risk communication was significantly correlated with COVID-19 preventive behaviors (r=0.320, p<0.01). In the final model, where the explanatory power increased with the entry of the risk communication variable, the variables explained a total of 14% of variance in COVID-19 preventive behaviors. Sex (ß=-0.482), risk perception (ß=0.047), and risk communication (ß=0.662) were significant determinants. CONCLUSION: Risk communication and risk perception related to COVID-19, as well as being a woman, were determinants of COVID-19 preventive behaviors.
RESUMO
Background: Suicide attempt is a serious global public health issue. The patterns of suicide may vary depending on the individual characteristics, methods, causes, and the geographical area-also socio-cultural context that determine it. This study identifies the spatial patterns of suicide attempts in Kermanshah province, Iran. Method: The sample size of this cross-sectional study is 18,331 people (7234 males and 11097 females) who attempted suicide in Kermanshah province between 2006 and 2014. Data was collected from the records of patients referred to the emergency department of hospitals in Kermanshah and analyzed using tests of Mean Center, Standard Distance, and Average Nearest Neighbor. Results: The results of the mean center and standard distance tests show that drug overdose, poisoning with toxins and pesticides, and chemicals mostly were used in the central areas of Kermanshah province. The mean center of suicide attempts by self-immolation, hanging and firearms was in the western parts of the province, while the suicide attempts with narcotic drug were concentrated in the eastern regions of the province. Out of the 18,331 cases, 74% attempted suicide with drug overdose, 13% with toxins and pesticides, 0.59% with chemicals, 4% with fire, 1% by self-immolation, 1% by hanging, 0.16% with firearms and 0.7% with cold weapons. The spatial pattern of all suicide attempts in Kermanshah was clustered (Z-score < -2.58). Conclusion: The results of this study show that the methods of suicide attempt vary with geographical areas in the province. Therefore, it is suggested that planning tailored to the geographical location can reduce suicide attempts in Kermanshah.

Objective: Investigating the trends of child diarrhea-related mortality (DRM) is crucial to tracking and monitoring the progress of its prevention and control efforts worldwide. This study explores the spatial patterns of diarrhea-related mortality in children under five for monitoring and designing effective intervention programs. Methods: The data used in this study was obtained from the World Health Organization (WHO) public dataset that contained data from 195 countries from the year 2000 to 2017. This dataset contained 13,541,989 DRM cases. The worldwide spatial pattern of DRM was analyzed at the country level utilizing geographic information system (GIS) software. Moran's I, Getis-Ord Gi, Mean center, and Standard Deviational Ellipse (SDE) techniques were used to conduct the spatial analysis. Results: The spatial pattern of DRM was clustered all across the world during the study period from 2000 to 2017. The results revealed that Asian and African countries had the highest incidence of DRM worldwide. The findings from the spatial modeling also revealed that the focal point of death from diarrhea was mainly in Asian countries until 2010, and this focus shifted to Africa in 2011. Conclusion: DRM is common among children who live in Asia and Africa. These concentrations may also be due to differences in knowledge, attitude, and practices regarding diarrhea. Through GIS analysis, the study was able to map the distribution of DRM in temporal and spatial dimensions and identify the hotspots of DRM across the globe.

Introduction: One of the major challenges in developing countries is the inappropriate spatial distribution of medical laboratory centers (MLCs) which can lead to injustice in access to health services. This study aimed to investigate the accessibility to and site suitability of MLCs in Kermanshah Metropolis by GIS. Materials and methods: In this cross-sectional study, data were collected from the Iran Statistical Center and Deputy of Treatment of Kermanshah University of Medical Sciences. We used Arc/GIS 10.6 software, AHP technique, and network analysis tools to determine the access status of Kermanshah citizens to MLCs in 2019 and site selection for MLCs. The layers used in this study included population density, city development trends, compatible and incompatible land uses, pathways, land slope, river area, and access radius. Results: About 70% of households had inappropriate access to all MLCs in walking scenario. This ratio was 31.26% for 5 min, 9.58% for 10 min, and 6.09% for 15 min driving. Comparisons between public and private MLCs showed that in walking scenario, 88% of households had improper access to public and 80% to private MLCs. Based on 5 and 10 min of driving, 57 and 19% of households had inappropriate access to public MLCs, and 45 and 17% to private MLCs, respectively. Also, with 15 min of driving, 8% of households had improper access to public and 18% to private MLCs. Findings showed that scores provided for population density criteria were (0.298), distance from existing laboratories (0.213), proximity to pathways (0.175), consistent land use (0.129), city development trend (0.087), distance from riverfront (0.053), distance from incompatible land uses (0.015), and land slope (0.03). The final model was obtained by overlaying the layers. The model showed a 9-degree range from very bad to very good in Kermanshah city for the construction of laboratory centers (CR<0.01). Conclusion: The site selection model showed that the location of the proposed centers can be in the north and outskirts of the city to facilitate citizens' access to the MLCs. These results emphasize the justice in the spatial distribution of MLCs for the benefit of deprived populations as a global value.

BACKGROUND: Health equity is directly associated with the proper distribution of resources, the existence of infrastructures, and the balanced physical environment. The present study aimed to survey the indexes of health equity in the physical environment and infrastructures of Kermanshah province based on the national indexes. RESULTS: The results revealed that access to transportation, health centers, solid waste management, and green and sports per capita had the least distance from the negative ideal whereas the noise pollution index had the greatest distance. However, house hygiene and air pollution indexes were within the negative and positive ideal ranges. CONCLUSIONS: The health equity indexes were not distributed equitably across counties and geographical regions of Kermanshah province.
RESUMO
BACKGROUND: Over the past few decades, various goals have been defined to reduce the mortality of children caused by acute lower respiratory infections (ALRIs) worldwide. However, few spatial studies to date have reported on ALRI deaths. PURPOSE: We aimed to assess the spatial modeling of mortality from ALRI in children under 5 years of age during 2000-2017 using a global data. METHODS: The data on the mortality of children under 5 years old caused by ALRI were initially obtained from the official website of the World Health Organization. The income status of their home countries was also gathered from the Country Income Groups (World Bank Classification) website and divided into 5 categories. After that, in the ArcGIS 10.6 environment, a database was created and the statistical tests and related maps were extracted. The Global Moran's I statistic, Getis-Ord Gi statistic, and geographically weighted regression were used for the analyses. In this study, higher z scores indicated the hot spots, while lower z scores indicated the cold spots. RESULTS: In 2000-2017, child mortality showed a downward trend from 17.6 per 100,000 children to 8.1 and had a clustered pattern. Hot spots were concentrated in Asia in 2000 but shifted toward African countries by 2017. A cold spot that formed in Europe in 2007 showed an ascending trend by 2017. Based on the results of geographically weighted regression test, the regions identified as the hot spots of mortality from ALRI in children under 5 years old were among the middle-income countries (R2=0.01, adjusted R2=8.77). CONCLUSION: While the total number of child deaths in 2000-2017 has decreased, the number of hot spots has increased among countries. This study also concluded that, during the study period, Central and Western Africa countries became the main new hot spots of deaths from ALRI.
RESUMO
BACKGROUND: Quality of life (QOL) is one of the major factors to assessing the health and wellbeing of People living with HIV (PLWH). Likewise, improved QOL is among the prominent goals of patient treatment. This study was conducted to investigate the QOL of PLWH in Kermanshah, Iran. METHODS: This cross-sectional study was conducted on 364 PLWH of Kermanshah between 2016 and 2017. Outpatients were selected as the sample through the convenience sampling method from HIV Positive Clients of Kermanshah Behavioral Diseases Counseling Center. The reasons for the selection of outpatients include: (a) some patients were substance users, homeless or did not have a fixed address to follow-up; (b) addresses and personal details that were registered on the first admission were incorrect or incomplete; (c) due to financial issues, some were forced to relocate frequently and were difficult to track; (d) some patients were convicts or prisoners, making it hard to find them after their release; (e) some of them were from other provinces, where managing access was not easy/possible. Data was collected using WHOQOL-HIV BREF questionnaire (Persian Version). Data also analyzed with STATA 14, and SPSS 23 using T-test and multiple regression. RESULTS: This study showed that mean (SD) age of PLWH was 40.21 (10.45) years. Females had better QOL than males except for spirituality, religion and personal beliefs. The gender differences disappeared in multivariate results. A significant association was observed between education and the independence, environment, and spirituality domains of QOL. In addition, being married was correlated with overall QOL, psychological and social relationships domains of QOL of PLWH. Drug use was a behavioral factor with negative influence on the QOL. CONCLUSION: This study found that marital status and drug use were the main predictors of various domains of QOL. Drug use was a behavioral factor with a negative influence on the QOL. Hence, it is recommended that health professionals, planners, and policymakers take effective measures to improve the status quo.

BACKGROUND: Inappropriate distribution of health centres can increase inequities in health care. A geographic information system (GIS) is a useful tool to help plan, monitor and evaluate health systems by analysing and visualizing geospatial data. AIMS: This study aimed to propose an optimal model for establishing new health centres in the city of Kermanshah, Islamic Republic of Iran using GIS. METHODS: In this descriptive analytical study, the number and location of health centres and people's access to them across Kermanshah were evaluated using the GIS system, ArcGIS 10.3, for the years 1997, 2007 and 2012. To determine the best locations for establishing health centres, five principles were considered: access, distance, service delivery radius, proximity to areas of compatible and incompatible land-use, and population density. RESULTS: In spite of an increase in the number of health centres in Kermanshah between 1997 and 2012, the population without access to such centres also increased, and this varied by age group. Based on the final map of all the land in Kermanshah, 6% of the land was considered unsuitable or very unsuitable, 16% medium suitability, and 78% good or very good for the location of health centres in Kermanshah city. CONCLUSION: The spatial distribution of health centres (in terms of the radius of access) and compatibility of the land-use were not properly considered over the 15-year period. To provide health coverage for the current population in the city of Kermanshah, 13 new health centres are needed in suitable locations.

Since the late 20th century, identifying the multidimensional nature of HIV/AIDS and its negative effects on mental health and quality of life (QOL) in patients has prompted specialists to identify and control the psychological and behavioural variables resulting from this disorder. Thus, the current study aimed to assessing the relationship between life satisfaction (LS) and QOL among people living with HIV/AIDS in Kermanshah. This descriptive-correlation study was conducted on 364 HIV/AIDS patients referred to the Voluntary Counseling and Testing Center (VCT) in Kermanshah in 2016-2017, selected by convenience sampling method. Data gathering tools included Satisfaction with Life Scale (SWLS), World Health Organization Quality of Life-HIV Brief (WHOQOL-HIV BREF) questionnaire and demographic checklist. The Cronbach's alpha reliability coefficient varied from 0.70 to 0.83 for the five subscales of WHOQOL-HIV BREF questionnaire. The result showed that out of 364 patients, 38.19% were women. There was a positive correlation between LS and QOL in patients with HIV/AIDS in Kermanshah (p < .001), and LS was associated with the QOL. Furthermore, the results indicated that LS and QOL in patients with HIV/AIDS were at low levels.

INTRODUCTION: Children are among the most vulnerable groups in society, whose health is of prominent significance. Moreover, as a group of clients with special needs in the health care system, they require special attention. Therefore, the present study aimed to investigate the 0-14-year-old children's access to health centers in rural areas of Kermanshah Province, Iran. MATERIALS AND METHODS: In the present cross-sectional study, both the latest published demographic statistics related to the Population and Housing Census, announced by the Statistical Center of Iran in 2011, and the information about the public and private hospitals in the province, collected by Kermanshah University of Medical Sciences, were used as the basis for the analyses. In addition, given the importance of the spatial nature of the research, geographic information system was used for data analysis, and a buffer model was also applied. RESULTS: The results revealed that out of the total population of 0-14-year-old children residing in rural areas within 15,000 and 30,000-km radii of Kermanshah Province, 87.94% and 75.11% of girls versus 88.15% and 75.38% of boys lacked access to health centers, respectively. CONCLUSION: It was found out that the 0-14-year-old children's access to health centers was in poor condition in rural areas of Kermanshah Province, which would endanger the health of this age group.
RESUMO
BACKGROUND: Quality of life is an important indicator for measuring health status, and information on quality of life of different groups in society can be used to assess the effect of interventions on health. AIMS: This study aimed to assess the relationship between urban poverty and perception of family socioeconomic status, and health-related quality of life in residents of informal settlements. METHODS: A cross-sectional study was conducted among 432 residents of two neighbourhoods of informal settlements in Kermanshah in 2015. To measure poverty, the 16 indicators of 2011 Iranian census were used. The neighbourhoods were classified into three groups: high poverty (9.3%), middle poverty (49.2%) and low poverty (41.5%) levels. Health-related quality of life was assessed with the SF-36 questionnaire. The Pearson correlation coefficient was calculated and regression and ANOVA analyses were done. RESULTS: There were no statistically significant differences between the SF-36 scores for the three poverty levels, and no relationship between poverty and the health-related quality of life subscales (P > 0.05). A significant positive correlation was found between perception of family socioeconomic status and health-related quality of life (P < 0.05). In regression analysis, having a chronic illness, perception of family socioeconomic status, age and sex predicted the physical health domain of the SF-36, whereas perception of family socioeconomic status and having a chronic illness predicted the mental health domain. CONCLUSIONS: Subjective perception of family socioeconomic status can explain differences in health-related quality of life of low-income people.

BACKGROUND: One-third of each woman's life is naturally during her menopause. This study was conducted to determine the factors related to the quality of life in postmenopausal women. MATERIALS AND METHODS: This cross-sectional study was carried out using cluster sampling method on 218 postmenopausal women aged 40-60 years old in Kermanshah in 2014. The data were collected through interview and with the standard questionnaire of Menopausal Quality (MENQOL) of Life and analyzed using SPSS software version 19. RESULTS: The mean age of menopause was 50.03 ± 4.48 years. Mean scores of quality of life and four domains, vasomotor, psychosocial, physical and sexual were 3.15±0.970, 3.71 ± 1.81, 3.32±0.959, 2.91 ± 1.06, 3.74 ±1.59, respectively. CONCLUSION: Chronic conditions such as hypertension in postmenopausal women can lead to lower quality of life. Therefore, provision of coherent support programs for controlling chronic diseases requires serious intervention from health care providers.
RESUMO
BACKGROUND: Nowadays, the significance of applying Geographic information system (GIS) to survey accessibility to hospitals and understanding disparities in this regard has increased. AIMS: The main aim of this descriptive-analytical research was to study the spatial accessibility of the population of Kermanshah for 3 years 1997 (n=693157), 2007 (n=794863), and 2012 (n=851 405) to hospitals based on age and gender groups through GIS. METHODS: The study was conducted based on network analysis models, mean centre, and standard distance in the environment of Arc/GIS. A standard radius of 1500 metres was set for the medical centres, and a 25-minute walking span was set for the distance of each person from home to the nearest hospital. RESULTS: The results of the network analysis demonstrated that the hospitals were inaccessible to the populations according to our criteria, and their geographical access to hospitals measured 68.80%, 64.23% and 66.20% in 1997, 2007, and 2012, respectively. Women aged 65 years and above were more at risk in this regard. CONCLUSIONS: Over the total period under study, the results revealed that hospitals were concentrated in the central and southern areas of Kermanshah.

INTRODUCTION: The trend of cancers has witnessed a twofold rise in the last three decades, which is expected to be fivefold by 2030. On the other hand, gastrointestinal cancers have turned into one of the health issues in many societies. Given the presence of gastrointestinal cancer hot spots and evidence of health inequalities across Kermanshah Metropolis and the results of studies signaling the association between gastrointestinal cancers and socioeconomic status of individuals as well as evidence of unequal socioeconomic opportunities in this metropolis, the present study aimed to investigate the spatial distribution of gastrointestinal cancers in the poverty and affluent strata of Kermanshah Metropolis, Iran. MATERIALS AND METHODS: In this descriptive-analytical study, the recorded data of patients, suffering from gastrointestinal cancers, in Kermanshah-based Pathology Centers and Vice Chancellery of Kermanshah University of Medical Sciences (2007-2012) were used. Moreover, to examine the status of gastrointestinal cancers in socioeconomic classes based on the census data collected during 2007-2012, 33 social, cultural, and structural indexes were extracted from the statistical blocks. Additionally, for data analysis and factor analysis, Kruskal-Wallis Test in the environment of SPSS and kernel density estimation (KDE) and Moran's I tests in the GIS environment were employed. FINDINGS: The results of the present study revealed that the distribution of poverty (Z score = 48.916518, p value = 0.000000) and affluent strata (Z score = 14.345028, p value = 0.000000) followed clustered patterns (p < 0.01). Additionally, the results indicated that the spatial distribution pattern of the upper gastrointestinal cancer was clustered (Z score = 1.896996, p value = 0.007828), whereas the spatial distribution pattern of the lower gastrointestinal cancer was inclined to a randomized clustered pattern (Z score = 1.338121, p value = 0.000857) (p < 0.01). Finally, seven main hot spots were identified from the poverty stratum in Kermanshah, which perfectly overlapped the hot spots of upper gastrointestinal cancer. Similarly, four main hot spots were identified from the affluent stratum in Kermanshah, which overlapped the hot spots of lower gastrointestinal cancer. The results of the Kruskal-Wallis Test demonstrated that the poverty and affluent strata were significantly different from each other in terms of gastrointestinal cancer: upper gastrointestinal cancer (p < 0.05 and X2=10.064) and lower gastrointestinal cancer (p < 0.05 and X2=10.253). CONCLUSION: The results of the present study showed that the ratio of patients with lower gastrointestinal cancers was higher than the incidence of upper gastrointestinal cancers over the 5-year period under study. Moreover, in Kermanshah Metropolis, there was a significant difference between the upper gastrointestinal cancer in the poverty stratum and the lower gastrointestinal cancer in the affluent stratum. Hence, it is suggested that GIS be applied as a tool for identifying the patterns of effective factors of this type of cancer in each social class, and it is recommended that some effective policies be presented and adopted by health managers according to the role and importance of socioeconomic, environmental, and nutritional factors in the poverty and affluent strata of society, and people at risk be equipped with preventive training programs in this respect.

INTRODUCTION: Road traffic injuries (RTIs) are considered as one of the most important health problems endangering people's life. The examination of the geographical distribution of RTIs could help policymakers in better planning to reduce RTIs. This study, therefore, aimed to determine the spatial-temporal clustering of mortality from RTIs in West of Iran. METHODS: Deaths from RTIs, registered in Forensic Medicine Organization of Kermanshah province over a period of six years (2009-2014), were used. Using negative binomial regression, the mortality trend was investigated. In order to investigate the spatial distribution of RTIs, we used ArcGIS. (Version 10.3). RESULTS: The median age of the 3231 people died in RTIs was 37 (IQRâ¯=â¯31) year, 78.4% were male. The 6-year average mortality rate from RTIs was 27.8/100,000 deaths, and the average rate had a declining trend. The dispersion of RTIs showed that most deaths occurred in Kermanshah, Islamabad, Bisotun, and Harsin road axes, respectively. The mean center of all deaths from RTIs occurred in Kermanshah province, the central area of Kermanshah district. The spatial trend of such deaths has moved to the northeast-southwest, and such deaths were geographically centralized. Results of Moran's I with respect to cluster analysis also indicated positive spatial autocorrelations. CONCLUSION: The results showed that the mortality rate from RTIs, despite the decline in recent years, is still high when compared with other countries. The clustering of accidents raises the concern that road infrastructure in certain locations may also be a factor. Regarding the results related to the temporal analysis, it is suggested that the enforcement of traffic rules be stricter at rush hours.

BACKGROUND: Cancer is one of the common causes of disability and mortality in the world. The present study aimed to define the spatiotemporal distribution of gastrointestinal tract cancers using a geographic information system (GIS) over the time period of 2007-2012 in Kermanshah-Iran. MATERIALS AND METHODS: The method of studying was descriptive-analytical as well as comparative with gastrointestinal tract cancer patients based in the City of Kermanshah over the time period covered. For data analysis, the GIS and SPSS 16.0 were applied. RESULTS: According to the pathological reports within the space of 5 years, 283 cases of gastrointestinal tract cancer (157 in males, 156 in females) were reported. The performed tests in terms of spatial distribution in the environment of GIS indicated that the disease demonstrated a clustered pattern in the City of Kermanshah. More to the point, some loci of this disease have emerged in the City of Kermanshah that in the first level, 6 neighborhoods with 29-59 cases of this disease per square kilometer and in the second level, 15-29 cases. CONCLUSIONS: Gastrointestinal tract cancer demonstrated an ascending trend within the space of 5 years of research and the spatiotemporal distribution of cancer featured a concentrated and clustered pattern in the City of Kermanshah.
