Economic evaluation of dialysis and comprehensive conservative care for chronic kidney disease using the ICECAP-O and EQ-5D-5L; a comparison of evaluation instruments.

BACKGROUND: Chronic Kidney Disease (CKD) patients often require long-term care, and while Hemodialysis (HD) is the standard treatment, Comprehensive Conservative Care (CCC) is gaining popularity as an alternative. Economic evaluations comparing their cost-effectiveness are crucial. This study aims to perform a cost-utility analysis comparing HD and CCC using the EQ-5D-5L and ICECAP-O instruments to assessing healthcare interventions in CKD patients. METHODS: This short-term economic evaluation involved 183 participants (105 HD, 76 CCC) and collected data on demographics, comorbidities, laboratory results, treatment costs, and HRQoL measured by ICECAP-O and EQ-5D-5L. Incremental Cost-Effectiveness Ratios (ICERs) and Net Monetary Benefit (NMB) were calculated separately for each instrument, and Probabilistic Sensitivity Analysis (PSA) assessed uncertainty. RESULTS: CCC demonstrated significantly lower costs (mean difference $8,544.52) compared to HD. Both EQ-5D-5L and ICECAP-O indicated higher Quality-Adjusted Life Years (QALYs) for both groups, but the difference was not statistically significant (p > 0.05). CCC dominated HD in terms of HRQoL measures, with ICERs of -$141,742.67 (EQ-5D-5L) and -$4,272.26 (ICECAP-O). NMB was positive for CCC and negative for HD, highlighting its economic feasibility. CONCLUSION: CCC proves a preferable and more cost-effective treatment option than HD for CKD patients aged 65 and above, regardless of the quality-of-life measure used for QALY calculations. Both EQ-5D-5L and ICECAP-O showed similar results in cost-utility analysis.

Socioeconomic and environmental factors associated with waterpipe tobacco smoking among Iranian adults: a PERSIAN cohort-based cross-sectional study.

BACKGROUND: Waterpipe tobacco smoking (WTS) is associated with several deleterious health outcomes. We sought to estimate the prevalence of WTS and explore socioeconomic inequalities associated with this culturally-rooted tobacco smoking practice among Iranian adults. METHODS: A cross-sectional analysis was conducted among 20,460 adults (ages 18 and older) enrolled in the PERSIAN cohort study during 2020. Data were collected on socioeconomic status (SES), lifestyle, alcohol consumption, cigarette smoking, and several risk factors related to non-communicable diseases. The concentration curve and relative concentration index (RCI) were administered to assess and quantify the SES-based inequality in WTS. RESULTS: Overall age-adjusted prevalence of past-month WTS was 5.1% (95%CI:4.6-5.8), with about 1% for women and 10.6 for men. Age-adjusted prevalence of WTS was higher among younger adults, men, cigarette smokers, obese adults, and those with higher SES. The RCI estimation showed that WTS is more popular among adults with high income and education. WTS was higher among younger adults, cigarette smokers, obese adults, and those with higher SES. CONCLUSION: There is a clear socioeconomic inequality in WTS, with a higher prevalence among adults with higher income and education. The findings suggest the need for targeted interventions to address this inequality and reduce the prevalence of WTS among high-income communities.

The socio-economic inequality in body mass index: a PERSIAN cohort-based cross-sectional study on 20,000 Iranian adults.

INTRODUCTION: The aim of the present study was to explore and determine the association between BMI and socio-economic factors in Iran. METHODS: Adults aged 35 to 70 (n = 20,460) were included from Ardabil Non-Communicable Disease (ArNCD) cohort study. BMI was calculated as kg/m2. Principal Component Analysis (PCA) was used to determine the socio-economic quintiles. Multivariate linear regression was performed to analyze the association of BMI as dependent variable with explanatory variables, Additionally, decomposition analyzing conducted to identify factors that explained wealth-related inequality in obesity. RESULTS: The prevalence of overweight and obese people was 83.7% (41.4% overweight and 42.5% obese) wherein the highest frequency of obese people belonged to the age group of 45 to 49 years old (19.9%) and to the illiterate people (33.1%). The results of multivariate linear regression model showed that age, being female, marriage, lower education level, having chronic disease, alcohol use, and higher socioeconomic level positively associated with obesity. The results of the decomposition model showed that the most important variables affecting socioeconomic inequality in higher BMI level were socioeconomic status (75.8%), being women (5.6%), education level (- 4.1%), and having chronic disease (2.4%). CONCLUSION: BMI showed significant association with socio-economic status, where richest people had significantly higher BMI than poorest group. Considering the direct role of high BMI in non-communicable diseases, new policies are needed to be developed and implemented by means of diet intervention and increased physical activity to control the BMI in the population of Iran.

Assessment of electrocardiogram interpretation competency among healthcare professionals and students of Ardabil University of Medical Sciences: a multidisciplinary study.

BACKGROUND: Electrocardiogram (ECG) interpretation is a core clinical skill that helps to rapid diagnosis of potentially life-threatening diseases. Misinterpretation of the electrocardiogram can lead to inappropriate clinical decisions with adverse outcomes. The main aim of this survey was to assess the competency of electrocardiogram interpretation and related factors among healthcare professionals and students of Ardabil University of Medical Sciences. METHODS: This descriptive cross-sectional study included 323 staff and students of Ardabil University of Medical Sciences in northwestern Iran. Data were collected randomly from November to January 1400 using the Badell-Coll ECG Interpretation Competency Questionnaire and analyzed using SPSS V.14. Statistical analysis included descriptive statistics, independent t-test, ANOVA, Pearson correlation coefficient and multiple linear regression. RESULTS: The results showed that the mean and standard deviation of electrocardiogram interpretation competency of health professional staff and students was 5.13 ± 2.25 (maximum score = 10). The large number of participants wasn't able to identify normal sinus rhythm (n = 251, 77.3%), acute myocardial infarction (n = 206, 63.8%) and pathological Q waves (n = 201, 62.2%). The results of multiple linear regression showed that the variables of education level, self-assessment of electrocardiogram interpretation competence, work experience, and type of hospital were able to predict the competence of ECG interpretation in participants. CONCLUSIONS: Our findings showed that the participants' level of electrocardiogram interpretation competency was low. Hence, regular, standard training and education are recommended. Also, managers and educators of the health system should consider the role of positive self-assessment and exposure to ECG interpretation in improving the competence of staff and students to interpret ECG.

Economic burden of cardiovascular diseases before and after Iran's health transformation plan: evidence from a referral hospital of Iran.

BACKGROUND: Different countries have set different policies to control and decrease the costs of cardiovascular diseases (CVDs). Iran was aiming to reduce the economic burden of different disease by a recent reform from named as health transformation plan (HTP). This study aimed to examine the economic burden of CVDs before and after of HTP. METHODS: This cross-sectional study was conducted on 600 patients with CVDs, who were randomly selected from a specialized cardiovascular hospital in the north-west of Iran. Direct and indirect costs of CVDs were calculated using the cost of illness and human capital approaches. Data were collected using a researcher-made checklist obtained from several sources including structured interviews, the Statistical Center of Iran, Iran's Ministry of Cooperatives, Labor, and Social Welfare, the central bank of Iran, and the data of global burden of disease obtained from the Institute for Health Metrics and Evaluation to estimate direct and mortality costs. All costs were calculated in Iranian Rials (IRR). RESULTS: Total costs of CVDs were about 5571 and 6700 billion IRR before and after the HTP, respectively. More than 62% of the total costs of CVDs accounted for premature death before (64.89%) and after (62.01%) the HTP. The total hospitalization costs of CVDs was significantly increased after the HTP (p = 0.038). In both times, surgical services and visiting had the highest and lowest share of hospitalization costs, respectively. The OOP expenditure decreased significantly and reached from 54.2 to 36.7%. All hospitalization costs, except patients' OOP expenditure, were significantly increased after the HTP about 1.3 times. Direct non-medical costs reached from 2.4 to 3.3 billion before and after the HTP, respectively. CONCLUSION: Economic burden of CVDs increased in the north-west of Iran after the HTP due to the increase of all direct and indirect costs, except the OOP expenditure. Non-allocation of defined resources, which coincided with the international and national political and economic challenges in Iran, led to unsustainable resources of the HTP. So, no results of this study can be attributed solely to the HTP. Therefore, more detailed studies should be carried out on the reasons for the significant increase in CVDs costs in the region.

The healthy behaviours and COVID-19 mortality among Iranian women: a case-control study.

BACKGROUND: Women are among the susceptible groups to Coronavirus disease-19 (COVID-19) in Ardabil, north-west of Iran, despite the current global status. The underlying causes of high incidence and fatality rate of women in Ardabil are not fully understood. Hence, this study aimed to investigate the healthy behaviours in women of Ardabil and its relationship with COVID-19 mortality. METHODS: We conducted a case-control study to compare the adherence to health protocols and behaviours with respect to COVID-19 between the infected (261 patients) and healthy (515 persons) women. Health protocols and behaviours such as using mask, gloves, disinfectants, history of travelling and contacting, and attending various gatherings and places during the COVID-19 pandemic along with demographic variables were defined as independent variables, and COVID-19 death rate was defined as the dependent variable. Multivariable logistic regression methods were used to explore the risk factors associated with COVID-19 mortality. RESULTS: Chi-square and Fisher tests showed significant differences between infected and healthy women in terms of history of contact and traveling (p < 0.05), wearing mask (p < 0.001), going to work place (p < 0.001), and attend public gatherings (p = 0.038). Multivariable logistic regression disclosed that the age group over 80 years: 8.97 times (95% CI 2.27-29.85), women with underlying chronic diseases: 4.14 times (95% CI 1.61-10.64), and obese women: 3.01 times (95% CI 1.04-6.03) were more likely to die from COVID-19 than other women. CONCLUSION: Considering the high incidence and mortality rate in Ardabil women due to COVID-19 and the corresponding health behavioural factors, special emphasis should be given to the increase of women awareness on the importance of healthy behaviours, diet, and life-style.

Five testicles in the genital area of a thirteen-month-old baby: a case report.

BACKGROUND: Polyorchidism is a congenital anomaly of the urogenital system and means more than two testes. It is a rare phenomenon, where there are no more than 200 reported cases in the literature. In this case, we report a 13-month year's old case with five testicles. CASE PRESENTATION: We report a rare five testicles in the genital area of a 13-month-old baby. The initial diagnosis was undescended testis (UDT) based on ultrasound findings where a testis in the abdomen and a testis in the inguinal canal were detected. Surgery with general anaesthesia was performed to diagnose and treat this case. Before surgery, four HCG 1200u injections were administered. During the operation, it was determined that the case had had five testicles. Testicles were on the left in the proximal inguinal canal, and the sac hernia was ligated parallel to the inner ring. The patient was followed up several times after surgery by a urologist, and the results showed that there were no problems, and the intervention was uncomplicated. CONCLUSION: Based on the result, it is not possible to diagnose such cases only by examination or ultrasound in infant patients, as the patient often presents with undescended testis (UDT), so the disease is diagnosed only through surgery.

Exploring the changes of physicians' behaviour toward informal payment based on Health Transformation Plan in Iran: A qualitative study.

By implementation of the Health Transformation Plan (HTP), a revised tariff system for healthcare services was executed in Iran. This study explores the changes in physicians' behaviour in facing informal payment (IP) based on HTP implementation in Iran. We conducted in-depth semi-structured interviews with 15 purposefully selected physicians and policy makers to explore the changes (positive, negative and no) in physicians' behaviours with and without the implementation of HTP. The interviews were conducted individually and face to face. The conventional content analysis for data analysis by MAXQDA ver.10 was used. Based on the results, regardless of the HTP implemented, market competitiveness could control physicians' demand for IP. However, unreal tariffs, irregular payments, inflation, expensive healthcare and comparing income with other occupations increase physicians' demand for IP as negative behaviour. This study explored three patterns of physicians' behavioural change because of HTP implementation: 1-positive behavioural change with four factors; 2-negative behavioural changes with two factors; and 3-no behavioural change with four factors. Various factors influenced physicians' behaviour towards IP with and without the HTP. To combat IP more efficiently, we recommend strengthening the HTP's positive interventions, compensation of physicians' target income, enhancing supervision, reducing the gap among various medical specialities and taking a systematic approach with law offenders.

Dual practice and multiple job holding among Iranian general practitioners: Rate and effective factors.

BACKGROUND: Physician's dual practice is a common phenomenon in both developing and developed countries. This study aimed to investigate the rate and factors affecting the dual practice of general practitioners (GPs) as the most important primary care providers in Iran. METHODS: This cross-sectional study was conducted on the data of 666 Iranian GPs, derived from a national survey. In this work, a researcher-made checklist was used to collect the required information. Multinomial logistic regression was used to examine the factors affecting concurrent employment in both public and private sectors and the factors affecting employment in more than one place (either public or private). RESULTS: About 23.51% of the GPs were only working in the public sector, and 57.84% only in the private sectors. Also, 18.65% were working in both the private and public sectors. Results also indicated that 26.17% of the GPs were working in two or more places (whether public or private). Male GPs (p < .1) as well as the GPs with higher earnings expectations (p < .01) were more likely to have dual practice. Besides, the GPs working in small towns and villages (compared with Tehran, as capital of Iran; p < .05) were less likely to have dual practice. Gender (male) and earnings expectations had a significant effect on working in more than one place (p < .01). CONCLUSION: The most important and significant factor affecting GPs' dual practice in Iran was their financial expectations. Thus, appropriate policies to modify physicians' income expectations and reforms such as improving tariffs setting should be adopted in the health systems.

Health insurance deductions in Iranian public hospitals before and after the health transformation plan.

Background: Developing countries, such as Iran, have been struggling with high rates of insurance deduction. As part of the Health Transformation Plan (HTP) in Iran, a new reference book was introduced to update the medical tariffs. This study aimed to compare the rates and extent of insurance deductions before and after HTP in Iran's public hospitals. Methods: This was a quasi-experimental study. Overall, 400 medical bills were selected from Iran's national Health Information System using multilevel random sampling before and after HTP implementation (2014 and 2017). Insurance deductions were divided into 5 groups: (1) diagnostic procedures, (2) medication and medical appliances, (3) accommodation and human capital provision, (4) surgery, and (5) other services. Using STATA Version 14.0, independent t test and Fisher's exact test were used for data analysis. Significance level was set at 0.5. Results: There was a significant decrease in insurance deductions among Iran's Health Insurance (HI) and Social Security Insurance (SSI). Accordingly, before HTP, the average amount of insurance deductions was 58.9% and 71.3% in HI and SSI, respectively. Moreover, there was a significant decline in all 5 groups between the pre- and postimplementation of HTP (p<0.05). Based on the results, hospitalization time (OR=2.31, 95% CI=1.9-3.2), patients in general hospitals (OR=1.49, 95% CI=1.4-2.7), coverage by SSI (OR=2.54, 95% CI=1.8-5.6), and having surgery (OR=3.5, 95% CI=2.0-7.3) increase the chance of insurance deduction significantly (p<0.05). Conclusion: Findings of this study showed that after HTP, insurance deductions were decreased significantly. The causes of this decline may be due to the range of services covered by public insurances, increase in insurance coverage, and improvement in health providers-insurance companies communication.

Service quality in Iranian hospitals: A systematic review and meta-analysis.

Background: This study aimed to explore service quality in Iranian hospitals by a systematic review and meta-analysis of the existing literature. Methods: The literature search in the international (PubMed, Scopus, and the ISI) and Iranian (SID, Iranmedex, and Magiran) scientific databases was conducted to identify studies (published in English and Persian) used the service quality gap (SERVQUAL) model to examine service quality in Iranian hospitals between 2000 and 2016. The databases were searched using a combination of the following keywords: "hospital service quality", or "healthcare service quality", and "SERVQUAL model", or "gap model", and "Iran". A random-effects meta-analysis model was used to investigate the quality of hospital care in Iran. Results: A total of 13 articles with 4,217 patients were included in the study. Results indicate that there are negative gap values between patients' expectations and perceptions in six SERVQUAL dimensions namely. tangibility, reliability, responsiveness, assurance, empathy, and access. The overall mean score of patients' expectations and perceptions of quality of hospital care in Iran were estimated 4.59 and 3.69, respectively (i.e., quality score gap= -0.9). The highest and lowest quality score gap values were related to the reliability and responsiveness dimensions, correspondingly. Conclusion: The study found that expectations of patients from hospital care have not been met in Iran. Thus, improving service quality in Iranian hospitals warrants further attention by health professionals, health policy-makers, and hospital managers.

Period Prevalence and Reporting Rate of Needlestick Injuries to Nurses in Iran: A Systematic Review and Meta-Analysis.

The purpose of this systematic review and meta-analysis was to provide a precise estimate of the period prevalence of needlestick injuries (NSI) among nurses working in hospitals in Iran and the reporting rate of NSI to nurse managers. We searched both international (PubMed, Scopus and the Institute for Scientific Information) and Iranian (Scientific Information Database, Iranmedex and Magiran) scientific databases to find studies published from 2000 to 2016 of NSI among Iranian nurses. The following keywords in Persian and English were used: "needle-stick" or "needle stick" or "needlestick," with and without "injury" or "injuries," "prevalence" or "frequency," "nurses" or "nursing staff," and "Iran." In a sample of 21 articles with 6,480 participants, we estimated that the overall 1-year period prevalence of NSI was 44% (95% confidence interval [CI], 35-53%) among Iranian nurses. The overall 1-year period prevalence of reporting NSI to nurse managers was 42% (95% CI, 33-52%). In meta-regression analysis, sample size, mean age, years of experience, and gender ratio were not associated with prevalence of NSI or reporting rate. The year of data collection was positively associated with period prevalence of NSI (p < .05), but not with the period prevalence of reporting NSI to nurse managers. Results indicated a high NSI period prevalence and low NSI reporting rate among nurses in Iran. Thus, effective interventions are required in hospitals in Iran to reduce the prevalence and increase the reporting rate of NSI. © 2017 Wiley Periodicals, Inc.

Effect of the COVID-19 pandemic on depression, perceived stress and hypochondria of frontline dental staff (FDS): A cohort study.

BACKGROUND: The coronavirus 2019 (COVID-19) pandemic had several mental effects on medical staff. OBJECTIVE: This study intended to evaluate deviations in Frontline Dental Staff (FDS) depression, perceived stress and hypochondria during the COVID-19 outbreak, and to assess whether the existence of potential risk-factors influenced these symptoms over time. METHODS: This prospective cohort study surveyed FDS three periods from February 1, 2021 to April 8, 2022. FDSs' mental health was assessed through Beck Depression Inventory, Cohen Perceived Stress and the Evans Self-Illness Questionnaires; multivariate linear regression were used to identify potential factors associated with changes on each outcome (depression, perceived stress and hypochondria) over time. All analyses were performed in STATA ver. 14. RESULTS: In a total of 635 FDS, about 69%, 83%, and 71% reported relative depression, 77%, 87%, and 64% reported moderate to high stress level, and 60%, 76% and 74% reported moderate hypochondriac from first, second, and third survives, respectively. The mean and standard deviation of the variables increased dramatically at second survive (July 17 to October 21, 2021) and decreased again at third survive significantly. Being female, working in public sector, and low socioeconomic level were main predictors of higher levels of depression (p < 0.001) and perceived stress (p < 0.001). Perceived stress was a strong predictor of high-level depression (t  =  7.79, p < 0.001). CONCLUSION: FDSs' depression, stress and hypochondria were high and positively associated with being female, working in public-sector, and low socioeconomic level. To increase the effectiveness and decrease work burnout, psychological support should be provided.

Smartphone Photography as a Teledentistry Method to Evaluate Anterior Composite Restorations.

Objective: Today, teledentistry have gain more attention than past due to the advances in technology. The aim of this study was to compare the use of smartphone photography as a method in teledentistry with the face-to-face examination in the evaluation of anterior composite restorations. Materials and Methods: In this study, photographs of 24 composite restorations in patients attended to the clinic of Ardabil Dental School were obtained using a smartphone without any additional equipment and sent by email to 10 remote observers. As a gold standard method, these restorations were evaluated by an experienced expert in restorative dentistry a face-to-face examination. In both methods FDI criteria were used to evaluate the restorations and classified them as acceptable or not. Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy of the photographic method relative to face-to-face method were calculated. Furthermore the Mann-Whitney U test was used to statistically compare the two methods in detail. Results: The sensitivity, specificity, positive predictive value, and negative predictive value of the smartphone photography method was 69.35%, 48.72%, 87.34%, and 23.75%, respectively. A diagnostic accuracy of 65.97% was obtained. Statistically, in overall the photographic method rated the restorations as better than they were in reality (face-to-face examination) (p = 0.002). Conclusions: The diagnostic accuracy of the method of evaluating anterior composite restorations by smartphone photography was moderate and the use of this method in teledentistry, although was promising, needs to be improved.

The Relationships between Social Capital, Metabolic, and Behavioral Risk Factors of Non-Communicable Diseases: A Systematic Review.

Background: Contextual risk factors such as social capital have a vital role in affecting behavioral and biological risk factors of NCDs. We aimed to systematically identify the relationship between different aspects of social capital (SC) with metabolic, and behavioral risk factors of non-communicable diseases (NCDs). Methods: This is a systematic review. The period of study was 2000-2021. We searched the English international databases, i.e. PubMed/Medline, Scopus, and Web of Science. Studies that reported NCDs' metabolic and behavioral risk factors as independent variables, were excluded. We also included studies if they analyzed the association between SC and metabolic and behavioral risk factors of NCDs. Results: After the primary and quality appraisal process, 97 studies were entered in the final phase of the analysis. Five out of 18 studies reported an inverse association between SC and the level of alcohol drinking. Twenty-seven out of 32 studies reported a significant inverse association between SC and smoking and tobacco use, while only one study reported a significant positive association. Nine studies reported a significant inverse association between SC and high blood pressure. Three studies showed a significant inverse association between SC and diabetes. Seventeen studies indicated a significant positive association between SC and physical activity. Thirteen out of 17 studies reported a significant inverse association between SC, body mass index (BMI) and overweight. Conclusion: High SC, people's participation and interaction are vital in tackling NCDs. Evidence shows positive effects of SC on prevention, control and improvement of NCDs' metabolic and behavioral risk factors.

Gastric troubles in Iran: The role of social and economic factors in Helicobacter pylori infection.

Background: Helicobacter pylori infection is a major risk factor for gastric cancer in Iran, but the impact of socioeconomic factors on its prevalence is poorly understood. This study aimed to assess the socioeconomic inequalities and risk factors associated with H. pylori infection in Iran. Methods: This cross-sectional study was conducted based on the PERSIAN cohort study. A total of 20460 individuals aged 35 to 70 years in Ardabil, Iran were included in the study. H. pylori infection was determined based on stool tests and clinical records. Multilevel logistic regression models with random intercepts at household and community levels were used to identify risk factors associated with H. pylori prevalence. The concentration index (CIn) and concentration curve (CC) were employed to assess socioeconomic-related inequality. Results: In this study, 70.4% (CI 69.6-71.0) of the participants were infected with H. pylori, with a higher prevalence in women (71.2%) than men (69.6%). Age (OR: 1.37, CI: 1.17-1.61), sex (OR: 1.20, CI: 1.12-1.28), level of education (OR: 1.33, CI: 1.17-1.49), cardiac disease (OR: 1.32, CI:1.18-1.46), and BMI groups (OR: 2.49, CI: 1.11-5.58) were significantly associated with H. pylori infection based on the multivariable logistic regression. The results of the CIn and CC indicated that H. pylori were more prevalent among economically disadvantaged groups (CIn: -0.1065; [-0.1374 to -0.0755]). Conclusion: The prevalence of H. pylori in Iran is higher than in other developing countries, and significant socioeconomic inequality exists between the poor and the rich. To reduce the rate of gastric cancer, socio-economic and demographic factors, especially the poor and people with low levels of education, should be considered.

Investigation of the link between the type and concentrations of heavy metals and other elements in blood and urinary stones and their association to the environmental factors and dietary pattern.

BACKGROUND: Kidney and urinary tract stones are among the most common and important health problems, the prevalence of which is increasing nowadays due to a sedentary lifestyle, improper nutrition, destructive habits in fluid consumption, and improper use of medications. One of the causing factors in the formation of urinary stones is heavy metals. These metals present in tiny amounts in the environment and enter the nature and food cycle due to industrial activities and practices that are not compliant with environmental laws. METHODS: In this context, the present case-control study was conducted to determine the concentrations of heavy metals and other urinary stone-forming elements in both blood and urinary stones and investigate their relationship with environmental factors and dietary patterns in people with urinary stones in Ardabil city in 2022. The sampling of blood and urinary stones was done randomly from patients with urinary stones who were admitted to the Urology Clinic of Imam Reza Hospital, Ardabil. ICP-MS was used to measure the concentrations of heavy metals in the samples. The obtained data were analysed by chi-square test, ANOVA test, t-test, and Tukey test. RESULTS: The body mass index (BMI) was 27.39 ± 3.72 in the case group and 26.37 ± 2.95 in the control group. The copper and selenium concentrations in blood and urinary stones were higher than in other metals. There was a significant relationship between the history of kidney stones and the probability of developing kidney stones. Moreover, a meaningful relationship was found between the concentration of lead element and the formation of kidney stones. The results showed a significant difference in the concentration of nickel and copper in people who consumed vegetables on a daily basis with those with different types of kidney stones. CONCLUSION: The comparison amongst the concentration of heavy metals in various kinds of urinary stones showed that the amount of lead metal was higher in calcium phosphate stones than in calcium oxalate stones.

Decomposition of Socioeconomic Inequality in Cardiovascular Disease Prevalence in the Adult Population: A Cohort-based Cross-sectional Study in Northwest Iran.

OBJECTIVES: The incidence of cardiovascular disease (CVD) mortality is increasing in developing countries. This study aimed to decompose the socioeconomic inequality of CVD in Iran. METHODS: This cross-sectional population-based study was conducted on 20 519 adults who enrolled in the Ardabil Non-Communicable Disease cohort study. Principal component analysis and multivariable logistic regression were used, respectively, to estimate socioeconomic status and to describe the relationships between CVD prevalence and the explanatory variables. The relative concentration index, concentration curve, and Blinder-Oaxaca decomposition model were used to measure and decompose the socioeconomic inequality. RESULTS: The overall age-adjusted prevalence of CVD was 8.4% in northwest Iran. Multivariable logistic regression showed that older adults, overweight or obese adults, and people with hypertension and diabetes were more likely to have CVD. Moreover, people with low economic status were 38% more likely to have CVD than people with high economic status. The prevalence of CVD was mainly concentrated among the poor (concentration index, -0.077: 95% confidence interval, -0.103 to -0.060), and 78.66% of the gap between the poorest and richest groups was attributed to differences in the distribution of the explanatory variables included in the model. CONCLUSIONS: The most important factors affecting inequality in CVD were old age, chronic illness (hypertension and diabetes), marital status, and socioeconomic status. This study documented stark inequality in the prevalence of CVD, wherein the poor were more affected than the rich. Therefore, it is necessary to implement policies to monitor, screen, and control CVD in poor people living in northwest Iran.

Utilization of elderly health promotion services during COVID 19 in Iran: A cross-sectional study.

BACKGROUND: The outbreak of COVID-19 pandemic has made it difficult for older adults to utilize ordinary elder services. This cross-sectional study investigated the status of feeling the need, seek, and utilization of health promotion services among older adults in Ardabil, Iran, covered by the country's comprehensive health system during the pandemic. MATERIALS AND METHODS: This descriptive-analytical and cross-sectional study was conducted on 739 elderly people in Ardabil province. Cluster random sampling method was used for sampling. Data were gathered by referring trained individuals to the place of residence of the selected older adults Questionnaires were consisted of three parts: demographic information, household's economic status, and feeling the need, seek, and utilization from health promotion services. Multivariate logistic regression was used to separately model the need, seeking for, and utilization of health promotion services in STATA ver. 14. RESULTS: The mean age of the older adults in this study was 68.88 ± 4.72 years. The results indicate that men showed significantly greater need, seek for, and utilization of health promotion services during COVID- 19 than women. According to the results, people over the age of 80 had 4.08 times (95% confidence interval [CI]: 1.99-12.60) more need and utilization of health services than the older adults under 65 years. The results also indicate that use of health promotion services was significantly associated with being married (3.74, 95% CI: 1.22-2.62), having primary insurance and supplementary insurance (1.92, 95% CI: 1.21-3.12), and obesity (2.05, 95% CI: 1.13-3.76) in P < 0.05 level. Based on the results, people with chronic disease and obesity were more likely to utilize health promotion services. CONCLUSION: Findings suggest that the access and utilization of inpatient and outpatient health services by the elderly in the COVID-19 pandemic has somewhat decreased, which could be due to the fear of the disease being referred to health centers by the elderly. Hence, enabling conditions such as parental health care were major factors affecting health-seeking habits among the Iranian elder population.

Kidney stones among Iranian adults: Prevalence and socioeconomic inequality assessment in a cohort-based cross-sectional study.

Background and Aims: Kidney stone disease is a crystal concretion formed usually within the kidneys. The worldwide prevalence of kidney stones could be affected by numerous differences in socioeconomic, and environmental factors. The purpose of this study is to investigate kidney stones among Iranian adults aged between 35 and 70 years and the prevalence and evaluation of socioeconomic inequalities. Methods: In this, a cohort-based cross-sectional study was carried out among 20,427 participants of ArNCDs aged 35 and 70 years old. Kidney stone was defined as a dependent (and binary) variable while demographic and socioeconomic factors were considered independent variables. Multivariable logistic regression was used to identify the key socioeconomic factors affecting kidney stone prevalence in Ardabil. Results: The overall prevalence of kidney stones was 17.6 (95% confidence interval [CI]: 16.1-19.2) out of which 21.53% and 14.36% pertained to men and women and 14.18% and 23.17% pertained to the poorest and richest groups, respectively. There was a significant difference in the prevalence of kidney stones between men and women in terms of age, marital status, education level, chronic disease, body mass index, and socioeconomic status (<0.001). The prevalence of kidney stones had a positive correlation with age (1.7, 95% [CI]: 1.42-2.04) and socioeconomic status (1.5, 95% [CI]: 1.34-1.69), where the odds of kidney stones increased significantly by increasing age and socioeconomic status. Moreover, the kidney stone concentration index showed a pro-rich distribution wherein it was more common among wealthy people (higher socioeconomic status) 0.062 (95% [CI]: 0.051-0.072). Conclusion: The results of this study showed that there is significant inequality in the prevalence of kidney stones, where it was more common among the richest people. In addition, being men and old age are significantly related to kidney stones, so policymakers and physicians should consider these factors.
