Methods: this descriptive-analytical and applied study was conducted at the national level using the two-stage Hackman econometric method in Stata 16 software in 2021. The sample size was 6171 elderly households which data was extracted from different sections of the cost and income questionnaire of Iranian urban households in 2019. Results: Increasing age, education, and employment of the head of the household, increasing household size, having a private home, increasing per capita health expenditures and income of household had a positive effect on the probability of purchasing medical insurance. Increasing the age, level of education and employment of the head of the household led to an increase in out-of-pocket payments for the elderly household by 61164, 84466 and 140032 Rials per month, respectively. Having supplementary health insurance, living in provinces with high human development and being an elderly head of household increased the out-of-pocket payments to 606207, 849739 and 109274 Rials per month, respectively. Conclusion: Elderly households were less likely than other households to purchase supplementary health insurance and having supplementary health insurance by an elderly household led to an increase in out-of-pocket payments compared to other elderly households. Therefore, to reduce out-of-pocket payments, increase coverage Insurance of health goods and services required by the elderly as well as reduction of the elderly franchise is offered.","PeriodicalId":44423,"journal":{"name":"Salmand-Iranian Journal of Ageing","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79643753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study evaluates effects of an 8-week training protocol with selected Fallproof exercises on fear of falling and quality of life in the elderly. Methods & Materials: This is a quasi-experimental study that initiated in 2019. Population of the study includes 53 elderly from nursing homes in Rasht, from among which 24 individuals aged 60-74 were selected using convenience sampling based on inclusion criteria. The subjects were randomly assigned to experimental (n=12،66/41±4/41( and control (n=12،66/16±2/40) groups. Fallproof exercises include a range of multisensory exercises (visual, vestibular, and somatosensory), center of gravity control, postural strategies, and power training including toe and heel walking, knee flexion and extension, adduction and abduction. Training intensity was increased based on overload principle and individual differences in an 8-week training protocol, three times a week for 60 minutes. Paired t-test and covariance analysis were used for intra-group and inter-group comparisons, respectively. Data analysis was performed using SPSS at significance level of p<0.05. Results: Our results indicate that fear of falling p<0.001 and quality of life p<0.010 improved significantly in the experimental group while showing no differences in the control group. Conclusion: It is concluded that Fallproof exercises significantly improve quality of life and reduce fear of falling in the elderly. This is observed in improvements in the experimental group. Considering multidimensional effects of Fallproof exercises and multifactor nature of fear of falling, these training protocols can be applied in rehabilitation programs in care centers for the elderly.","PeriodicalId":44423,"journal":{"name":"Salmand-Iranian Journal of Ageing","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83722072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frail older patients are at increased risk of Emergency Department (ED) visits, hospitalization, and disability. The aim of this study was to determine the relationship between frailty syndrome and polypharmacy in the elderly referred to the emergency department of Ardabil teaching hospitals. Methods & Materials: In this cross-sectional descriptive study, 505 elderly people referred to the hospital emergency department were selected by convenience sampling method. Frailty syndrome was measured using the five-item criteria of fried which include: 1) slow walking, 2) muscular weakness, 3) exhaustion, 4) low physical activity and 5) unintentional weight loss. Polypharmacy considered the use of 5 or more drugs. Data were analyzed using descriptive statistics including mean and standard deviation and inferential analysis including analysis of variance, independent t-test, correlation, and multiple regression using spss 22 statistical software. Results:The mean age of participants was 70.91 ± 7.49 and 255 (50.5%) were male, 318 (63%) were married and 271 (53.7%) were illiterate. the results of the study showed that 204 (40.4%) of the elderly who referred to the emergency department had frailty and 177 (35%) had pre frailty. In this population, we identified a 42.2% (n=98) of frail with polypharmacy, 37.1% (n= 86) of prefrail with polypharmacy. The correlation test showed that there is a significant relationship between fertility and polypharmacy (p ˂0.001). Linear regression analysis showed the variables of age, education, living arrangement, hospitalization, and the number of medications used by the patient as predictors of frailty syndrome in the elderly referred to the emergency department. Conclusions:Number of drugs used, age, education, living arrangement and number of hospitalizations were predictors of frailty syndrome in the elderly. Considering the living conditions of the elderly and the prevention of unnecessary hospitalizations can reduce polypharmacy and ultimately a preventive strategy to prevent and manage frailty. Of course, further research is needed to confirm the possible benefits of reducing polypharmacy in the development, reversion, or delay of frailty.","PeriodicalId":44423,"journal":{"name":"Salmand-Iranian Journal of Ageing","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80722983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some economic theories consider the changes in the age structure and population aging as one of the important issues affecting the income inequality of societies. This study aims to assess the effect of population aging on the income inequality in Iran. Methods & Materials: This study was conducted in 2020 using economic data from 1970 to 2018 extracted from the websites of the Statistical Center of Iran and the World Development Indicators. First, a model for income inequality was presented and demographic variables were considered in the model. Then, its coefficients were estimated using the AutoRegressive Distributed Lag method in Eviews 10 software. To evaluate the speed of adjustment from the short-run to the long-run equilibrium, the Error Correction Model (ECM) was estimated. Results: The increase in aging population led to increased income inequality in the long run such that 1% increase in aging index caused a 0.14% increase in Gini index (P<0.05). The literacy rate, trade openness, and the square of Gross Domestic Product (GDP) per capita had a negative significant effect, and GDP per capita and the Consumer Price Index had a positive significant effect on income inequality, both in the short and long term. The ECM value was reported 44.8%. Conclusion: The aging of the population increases income inequality in Iran. Policymakers should reduce income inequality by investing in education and expansion of trading with other countries as well as stabilizing economic conditions, controlling inflation, and planning to reduce the effects of aging.","PeriodicalId":44423,"journal":{"name":"Salmand-Iranian Journal of Ageing","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87565399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
