Low physical activity and depression are the prominent predictive factors for falling in older adults: the Birjand Longitudinal Aging Study (BLAS).

BACKGROUND: Falling in the older adults has many irreparable consequences, including hospitalization to long-term care centers and loss of independence, depression and social isolation, financial burden, and death. The present study was conducted to estimate the incidence of falls and their associated factors among community-dwelling older adults. METHODS: This program is a population-based prospective cohort study (≥ 60 years) in Birjand City from 2019 to 2020. A total of 1418 participants were included in the study, and 1344 participants were analyzed according to the inclusion criteria. Thirty-nine risk factors were evaluated. Basic information included demographic information, lifestyle factors, general health and medical history, and mental and functional health. RESULT: The incidence of falls among community-dwelling older adults in the previous approximately 24 months in the present study was 9.26% in women and 2.65% in men. In the multiple Cox proportional regression model based on fall risk factors, there was a strong significant relationship between male sex (HR = 0.37, CI = 0.21 to 0.64), being physically active (HR = 0.59, CI = 0.36 to 0.96), moderate-to-severe depression (HR = 2.97, CI = 1.47 to 6.01), severe depression (HR = 3.26, CI = 1.24 to 8.54), and high risk of falls according to the TUG test (HR = 1.73, CI = 1.10 to 2.72). CONCLUSIONS: Inactivity and depression were recognized as important factors in falls in older adults. It is recommended for older adults to have an active lifestyle to prevent falls and to prioritize the diagnosis and treatment of depression in older adults. Women as a group at higher risk should be considered in prevention programs. In addition, the use of the TUG test to identify high-risk older adults should be considered.

Effects of hospital-to-home transitional care on health outcomes of elderly patients in Islamic Republic of Iran.

Background: Hospitalization has a negative effect on the functional and clinical outcomes of elderly patients. Aims: To evaluate the effect of a care transition intervention on functional and clinical outcomes and quality-of-life of elderly patients in the Islamic Republic of Iran after hospital discharge during a 3-month follow-up. Methods: We conducted a randomized controlled trial of 304 elderly hospitalized patients in Tehran from December 2018 to January 2020. The intervention group (n = 152) received care transition intervention and the control group (n = 152) received routine hospital discharge. All patients were assessed during hospital stay and at 30, 60 and 90 days after hospital discharge. Participants were evaluated using the Minimum Data Set-Home Care form, which assesses daily living activity, instrumental daily living activity, cognitive performance, cognition, pain, and depression. Rehospitalization and qualityof- life were evaluated, and differences between the groups and trends in quality-of-life were assessed. Results: Only instrumental daily living activity in the functional outcomes and quality-of-life were greater in the intervention group than the controls. The intervention (odds ratio (OR): 0.11; 95% confidence intervals (CI): 0.01-0.97), age (OR: 1.16; 95% CI: 1.01-1.33), and cognition (OR: 1.24; 95% CI: 1.02-1.51) predicted instrumental daily living activity. Age (coefficient: -0.009, P = 0.001), depression (coefficient: -0.157; P < 0.001), cognition (coefficient: -0.023, P < 0.001) and pain (coefficient: -0.106, P = 0.007) predicted quality-of-life. Conclusion: Care transition interventions can help maintain the independence of older adults after hospital discharge and improve their quality-of-life.

Working Condition and Job Satisfaction of Nurses as Predicting Factors of the Prevalence of Health care-associated Infections among Elderly Inpatients.

Background: Health care-Associated Infections (HCAIs) are among the most common adverse events (AEs) that can negatively affect both patients and health systems. The elderly is among patients at high risk for infections. Some controllable risk factors have received less attention in research. Therefore, this study aims to investigate the relationship between prevalence of HCAIs among elderly inpatients, job satisfaction of nurses, and working condition. Materials and Methods: This cross-sectional study was conducted on 211 nurses working in hospitals affiliated with Iran University of Medical Sciences, Tehran, in 2021. The data were collected from HCAIs reports by the Nosocomial Infection Control Committee, a demographic questionnaire, the Practice Environment Scale of the Nursing Work Index (PES-NWI), and the Minnesota Satisfaction Questionnaire (MSQ). The data were statistically analyzed using Pearson correlation coefficient, ANOVA, t-test, and multiple linear regression (MLR) in SPSS 26. Results: The results showed that there was a significant relationship between the PES-NWI and MSQ (r = 0.68, p < 0.00). The MLR results indicated that staffing and resource adequacy, nurse participation in hospital affairs, job satisfaction, nursing manager's leadership, and nursing foundations for quality of care are predictive factors that these could explain 78% of the changes in the prevalence of HCAIs and the goodness of fit of the regression model was acceptable [F6.210 = 129.47, p < 0.001]. Conclusions: Since job satisfaction and the work condition could predict HCAIs among the elderly patients, healthcare administers are recommended to consider these two variables in the development of HCAIs prevention and control programs.

The intergenerational relationship patterns between aging parents and their adult children.

Background: Older parent-child relations and their impact on the elderly's lives are of importance; thus, the present study aimed to investigate the patterns of the intergenerational relationships between aging parents and their adult children. Methods: The current cross-sectional study was conducted on 463 elderly men and women, aged ≥60 years who were residing in Tehran City, Iran. The study participants were selected using the stratified cluster sampling method. The Bai's (2017) 13-item Intergenerational Relationship Quality Scale for Aging Parents (IRQS-AP) was used to evaluate the patterns of intergenerational relationships among the study subjects. The obtained data were analyzed in SPSS. The significance level of the tests was set at P ≥ 0.05. The logistic regression model was employed to investigate the factors related to the patterns of intergenerational relationships. Results: The mean ± SD age of the explored aging parents was 67.93 ± 7.0 years. Besides, the mean ± SD number of children in the study participants was 3.55 ± 1.80. The mean ± SD scores of solidarity (structural, associational, consensual, affectual, functional, and normative) and conflict were measured to be (58.95 ± 17.55) and (64.10 ± 20.92), respectively. Furthermore, the mean ± SD score of the ambivalence pattern was calculated as (51.46 ± 21.61). The mean score of conflict was higher than those of solidarity and ambivalence. Additionally, the mean score of consensual-normative solidarity was higher than those of other dimensions of solidarity. The obtained data suggested a significant difference between age and the patterns of intergenerational relationships (p ≤ 0.05). Moreover, the mean scores of solidarity and conflict in the examined female elderly and their adult children were higher than those of their male counterparts and their adult children; however, the mean score of ambivalence in the male elderly and their adult children was higher than that in their female counterparts. Logistic regression analysis results indicated that aging parents who were literate (OR = 1.5), those who lived alone (OR = 1.2), and those who assessed their general health status as good (OR = 4), reported high levels of solidarity with their adult children. Conclusion: The present research results demonstrated that the level of conflict between aging parents and their adult children exceeded the solidarity level, indicating the intergenerational gap. Therefore, the necessary implications should be adopted to promote intergenerational relationships within the family by providing family counseling. Further research is recommended to consider the essential role of predictive factors, such as age, gender, educational level, occupational status, living arrangements, health status, and socioeconomic status of aging parents concerning the intergenerational relationships between aging parents and their adult children.

Older people's perceptions of intergenerational relationships in nursing homes: A qualitative content analysis.

Introduction: Intergenerational conflict is one of the components which helps to inappropriate communication patterns and ineffective interactions. Intergenerational research aims to promote deeper understanding and respect between generations and helps to create more cohesive communities, suggesting that it can have numerous health and social benefits. Despite the importance of intergenerational relationships in the elderly, the older people's perceptions of intergenerational relationships in nursing homes are not well understood. The purpose of this study was to explore the older people's perceptions of intergenerational relationships in nursing homes in relation to nurses. Methods: This was a qualitative content analysis in which 12 elderly residents and 6 employees (3 nurses, 1 supervisor, 1 psychologist and 1 nursing home manager) in the nursing home were recruited purposively from three nursing homes located in Tehran, Iran. Semi-structured interviews were used to collect information. Data were analyzed via qualitative content analysis and continuous comparison and were based on self-interactional group theory (SIGT). Results: During data analysis, "Struggle for existence" was extracted from three subthemes as the main theme. Subthemes such as "prejudicious tendencies", "Communication nodes" resulting from intra-group and inter-group analysis, respectively, and the "umbrella of society," which influences both concepts, formed the intergenerational relationships in the nursing homes. Conclusion: Generational differences between nursing home residents and nurses make establishing effective communication between them difficult and lead to lack of quality care. The study findings can help nursing home managers apply strategies to remove barriers to intergenerational relationships, improve these relationships and increase cohesion between generations to lead to better care and subsequent improvement in their quality of life.

Psychometric properties of the Persian version of the "Intergenerational relationship quality scale for aging parents and their children".

BACKGROUND: Investigating the status of intergenerational relationships of elderly parents with their adult childen is very important in examining issues related to the status of the elderly such as well being and quality of life and other aspects of elderly life. Giveeen the significance of the topic, the current study aimed to examine the psychometric properties of the Persian version of "Intergenerational Relationship Quality Scale for Aging Parents and Their Children" (IRQS-AP). MATERIALS AND METHODS: A total of 463 community-dwelling elders (aged 60 years or older) in Tehran participated in this study through multistage cluster sampling method. To investigate reliability, the construct and convergent validity of the IRQS-AP, confirmatory factor analysis (CFA), and interclass correlation coefficient were done. RESULTS: The content validity index was 0.84 for the entire tool. In the CFA, we found the instrument had a four-factor structure and adequate internal consistency. The scale had a significant and positive correlation with the two measures of loneliness and depression. Furthermore, Cronbach's alpha was estimated at 0.77, and the high value of the interclass correlation was 0.82. CONCLUSION: The IRQS-AP is a valid and reliable scale that can be used to examine the status of intergenerational relationship quality in Iranian elder population.

Facilitators and barriers for families caring for adults living with Alzheimer's dementia: A qualitative study.

This study investigates the barriers and promoters of caring for older adults living with Alzheimer's Dementia (AD) in families. This was a qualitative study through content analysis (based on the Granheim and Lundman method), and the participants were selected using purposive sampling from the families of older adults living with AD who were receiving care in the community. We used semi-structured interviews to collect data from 32 family members. The validity and reliability of the data were assessed using the Lincoln and Guba criteria. In this study, 70.58% of primary caregivers were women. Caregiving facilitators included "Efficient family," "Capable caregiver," and "Motivated caregiver." Caregiving barriers included "Lacking awareness and knowledge," "Vulnerable family," "Older person with complex/multiple needs," and "Lack of care infrastructures." Training families and caregivers and developing care infrastructures for older adults with AD can help reduce caring barriers in older adults.

Low physical activity is the strongest factor associated with frailty phenotype and frailty index: data from baseline phase of Birjand Longitudinal Aging Study (BLAS).

BACKGROUND: Frailty is the most complicated expression of aging that is related to disability or multi-morbidity. The aim of the present study was to estimate the prevalence of frailty and its associated factors among community-dwelling aged population. METHODS: A total of 1529 eligible community- dwelling older adults (≥ 60 years) were enrolled in the baseline phase of Birjand Longitudinal Aging Study (BLAS) from 2019 to 2020. Their frailty status was assessed using the Fried's frailty phenotype and frailty index. Sociodemographic factors, including sex, age, marital status, and education level, were collected. Health status assessment included the history of hypertension, diabetes mellitus, cardiovascular disease, Alzheimer's diseases and dementia, and other health conditions. Furthermore, functional assessment (ADL, IADL) and anthropometric measurements including height, weight, waist, calf, and mid-arm circumference were made and the body mass index was calculated. The nutrition status and polypharmacy (use 3 or more medication) were also evaluated. RESULTS: The prevalence of frailty was 21.69% according to the frailty phenotype and 23.97% according to the frailty index. A multiple logistic regression model showed a strong association between low physical activity and frailty phenotype (OR = 36.31, CI = 16.99-77.56, P < 0.01), and frailty index (OR = 15.46, CI = 5.65-42.34, P < 0.01). Other factors like old age (≥80), female sex, malnutrition, polypharmacy, obesity, and arthritis were also associated with frailty. The Kappa coefficient of the agreement between these two instruments was 0.18. CONCLUSION: It seems that low physical activity is the most important determinant of frailty. Low physical activity and some other factors may be preventable or modifiable and thus serve as clinically relevant targets for intervention.

The effect of toe-only rocker sole shoes on gait variability of the elderly.

Gait variability could associate with fall risk in older people. Rocker sole shoes are commonly prescribed to reduce plantar pressure and facilitate forward movement. Thus, it may affect gait stability. The purpose of this study was to investigate the effects of toe-only rocker shoes on gait variability in the elderly. Seventeen healthy elderly participants walked on a treadmill under six different conditions including barefoot (BF), normal shoe (NS), and four types of toe-only rocker sole shoes with various degrees of rocker angle (RS10, RS20, RS30, and RS40). Then the step length variability (SLV), the step time variability (STV), the step width variability (SWV), and the stance time variability were measured. Increasing rocker angle in toe-only rocker did not significantly affect gait variability more than the standard shoe. It seems that different rocker angles in toe-only rocker sole shoes do not pose a threat to gait variability compared to the standard shoes in healthy elderly. Findings of the study suggested that the toe-only rocker sole can be used to facilitate forward progression in the elderly. Further investigation is also required to examine the long-term effects of toe-only rocker sole shoes on gait variability in frail elderly.

Nonlinear analysis of dynamic stability in walking with toe-only rocker sole shoes in elderly.

BACKGROUND: Elderly subjects are at the risk of falling. One type of shoe intervention used for this group of the subjects is the shoe with rocker. The aim of this study was to investigate the effects of shoes with various degrees of rockers on dynamic stability of elderly subjects while walking. METHOD: 15 elderly subjects were recruited in this study. A motion analysis system was used to record the motions of body while walking on a treadmill. The local dynamic stability (LDS) was evaluated based on use of Lyapunov exponent of center of mass (COM) movement. The subjects were asked to walk barefoot, with shoe with no rocker and with shoe with various rockers (10, 20, 30 and 40°). RESULTS: The mean values of LDS (λmax-S) in anteroposterior direction were 0.95 ± 0.46, 0.78 ± 0.51 and 0.74 ± 0.54 in bare foot, shoes with no rocker and shoe with 10° rocker, respectively. The mean value of LDS (λmax-S) in vertical direction varied between 1.21 and 1.23. There was no significant difference between LDS of elderly subjects while walking with shoes with various rocker angles. DISCUSSION: Use of shoes with various rocker angles dose not influence on dynamic stability of elderly subjects while walking. Therefore, it is recommended to use this kind of shoe intervention for other trapeutic purposes.

Applicability of SPMSQ in illiterate outpatients in clinics: The validity and reliability of the Short Portable Mental Status Questionnaire.

OBJECTIVES: The Short Portable Mental Status Questionnaire is a brief cognitive tool designed to screen cognitive impairment in geriatric inpatients and outpatients. The validity and reliability of this tool have not been studied in Iran so far. Therefore, this study was conducted to assess the diagnostic properties of the SPMSQ for detection of cognitive disorders in elderly and determine an appropriate cutoff point based on respondents' level of education. METHODS: This cross-sectional study was conducted through face to face interviews on a sample of 156 patients (≥60 years) referred to neurology and geriatric clinics of Ziaiyan hospital, Tehran University of Medical Sciences. Regarding the type of cognitive impairment, Participants were divided into two groups; those with cognitive disorders (n = 96) and healthy (n = 60). The level of literacy was also considered in each of the groups. RESULTS: The Cronbach's alpha coefficient for the SPMSQ was 0.88. In terms of the concurrent validity, a correlation coefficient between SPMSQ and GDS was higher in the literate group compared to the illiterate patients, while in the illiterate group, the SPMSQ had a higher correlation with AMT compared to the other tools. Based on DSM-5, the cutoff point of SPMSQ was 4 in the illiterate elderly patients and the sensitivity and specificity of the tool were at 86.4 and 88.2%, respectively. However, in the literate patients, the cutoff point was 3 and the sensitivity and specificity were 83 and 93.7%, respectively. Also, two components, namely orientation and long-term memory/concentration were determined for the SPMSQ using the factor analysis. CONCLUSION: The Iranian version of SPMSQ has a favorable validity and reliability for diagnosing cognitive disorders and can be used for cognitive screening of illiterate older adults.

The conceptual and practical definitions of frailty in older adults: a systematic review.

PURPOSE: This study aimed to review and extract all publications containing concepts related to definitions of frailty and categorize them. METHODS: A total of six electronic databases (PubMed, Ovid web, Web of Science, Scopus, Embase, Cochrane Library, and ProQuest) were searched to identify studies that introduced a definition of frailty up to October 2018. No language restrictions were imposed. RESULTS: Totally, 104,370 papers were found in the initial search and finally 68 papers were included. Of these, 21 studies provided a conceptual definition and 50 original articles also 9 review articles provided a practical definition. Moreover, 12 papers had both definitions of frailty. Of them, 62 were published in English, 2 in Portuguese, 1 in Japanese, 2 in Korean, and 1 in German languages. CONCLUSION: Many screening tools have been developed but neither of them can cover a wide range of parameters at the same time, nor do they have simplicity in the execution. It is important to note that although a more or less general consensus on one single definition might be expected, we believe that the elderly population is too heterogeneous to allow a tool to address it as a whole, and such a definition may even be impossible. Therefore, in the absence of a "Gold Standard" definition, it is suggested to seek accurate knowledge of the strengths and weaknesses of each definition and choose the most appropriate definition and the most effective evaluation tool according to the purpose of the research and the characteristics of the older population.

Prevalence and Determinant Factors of Diabetes Distress in Community-Dwelling Elderly in Qom, Iran.

BACKGROUND: Diabetes distress (DD) is common among the patients with type 2 diabetes (T2D), but few studies investigated this problem and its related factors in the elderly population. This study has focused on the prevalence rate of DD and its determinants in community-dwelling elderly in Qom, Iran. METHODS: This study was cross-sectional. A total of 519 subjects community-dwelling with T2D participated in the study. Collected data contained sociodemographic information, some clinical variables (body mass index and duration of diabetes) knowledge, attitude, and self-efficacy. Participants' distress was measured via diabetes distress scale (DDS). The cut of 3 (≥3) was considered as the presence of distress. Also, the attitude, self-efficacy, and knowledge about diabetes were measured by questioner. Multiple logistic regression analysis was applied to detect predictors of DD. RESULTS: The mean age of the participants was 68.38 ± 6.78 and 53.6% were female. Among the participants, 48.6% were identified with positive DD. According to the results of logistic regression analysis, being female (odds ration [OR] = 1.688, P = 0.009), being widowed or divorced (OR = 1.629, P = 0.027), being over-weight or obese (OR = 1.627, P = 0.027), and having less than 10 years in disease duration (OR = 1.721, P = 0.029), attitude (OR = 0.590, P < 0.001), and self-efficacy (OR = 0.658, P = 0.009) were identified as the independent predictors of DD. No significant association was found between DD and age, occupational status, education level, and knowledge (P > 0.05). CONCLUSIONS: The prevalence of DD is considerable among the elderly in Qom. It seems that more attention should be paid to the mental aspects of the patients with T2D specially in high risk groups.

Care Process in Iranian Nursing Homes: A Grounded Theory Study.

Introduction: The need and use of long-term care services for older people has increased with their rising population and there is little information about the state of serving in nursing homes. This study aimed to identify the caring process in Iranian nursing homes. Methods: This qualitative study was conducted in three Iranian nursing homes using grounded theory approach. The participants included 28 individuals (14 older people and 14 caregivers). The data were collected using unstructured interviews up to data saturation, and analyzed by constant comparative method. Results: Fragmented care emerged as the core variable. The main factor for developing the core variable was 'experience-based caring'. Other factors included 'inappropriate structure for care' as contextual factors in the nursing homes environment and 'keeping instead of caring', 'dismal life', and 'up and down of the path' as strategies and consequences. Conclusions: The most common type of care was the routine and unplanned one with focusing on physical aspects. To improve a delivery care system for older people in nursing homes, proposing a care plan with focus on an integrated model of care in nursing homes, provision of instructions for treatment, as well as supervision and training caregivers to provide better care are necessary.

Determination of the correlation between muscle forces obtained from OpenSim and muscle activities obtained from electromyography in the elderly.

Measurement of muscle forces related to aging can help to better identify the gait impairment mechanisms in the elderly. To this end, musculoskeletal modeling has been developed to estimate muscle forces. This study aimed to check the validity of OpenSim modeling (i.e., computed muscle control) approach in elderly subjects. Kinematic and kinetic data and Electromyography (EMG) signals for four different muscles were collected in nine healthy elderly males during walking. Dynamic simulation was done within OpenSim. Correlation analysis was performed to quantitatively compare the maximum estimated muscle forces with maximum measured muscle activities during the first double limb support, single limb support, and the second double limb support phases. The area-time plots of OpenSim and EMG data during gait cycle were obtained for qualitative assessment. In quantitative assessment, a low to moderate correlation was observed for the peak of muscle force and muscle activation of four muscles during sub phases of gait. The muscle forces pattern from OpenSim was found to be relatively similar to the muscle activity pattern from EMG especially for Gastrocnemius Medialis. A low to moderate consistency between OpenSim and EMG in the elderly can be explained by using a single mathematical estimation approach.

Socioeconomic Determinants of Social Capital Inequality among Older Adults of Tehran: A Population-Based Study (Urban HEART-2).

Background: Social capital (SC) is an essential concept of communities, and there is more SC inequality. In the current study, we studied SC Inequality concerning the explanatory socioeconomic factors. Methods: In a cross-sectional observational study, the household data were retrieved from an Urban Health Equity Assessment and Response Tool survey in 2011. Over 5000 elderlies in Tehran (> 60 years old) consented toparticipate in the study and filled out 2 SC questionnaires (SCQ) and a household properties questionnaire (HPQ). Subsequently, the collected HPQ data were then statistically analyzed and used to measure the economic status of households. Besides, the statistical concentration index of the SC was applied to measure socioeconomic inequality and decomposed into its determinants using both SCQ and HPQ data collections. The concentration index and the decomposition analysis were used to analyze the study data. Results: The overall concentration index of the SC in Tehran senior citizens was 0.059 (95%CI,0.044-0.076). Among the SC dimensions, collective activity, social coherence, voluntary help, and social network were more concentrated in the poor older adults. Simultaneously, reciprocity was more focused onthe wealthy class, and there was no inequality in trust. The decomposition of the concentration index showed that economic status made the most considerable contribution to the SC inequality among citizens (69.11%), followed by the level of education (12.695) and the elderlies'job type (9.58%). Conclusion: Given that the economic status and level of education are the 2 main determinants of SC inequality, a holistic policy approach should be adopted to address the socioeconomic inequalities that are taken root in Tehran's senior communities.

Validity and reliability of Bayer Activities of Daily Living (Bayer- ADL) scale in the Iranian elderly dementia population: Is there distinguish between illiterate and literate demented in functional dependency?

This validation study is discriminant and concurrent, with the Bayer-Activities of Daily Living (Bayer-ADL) tool among the Iranian elderly dementia illiterate and literate. The tools Bayer-ADL, Global Deterioration Scale (GDS), Mini Mental State Examination (MMSE), ADL-Barthel, and instrumental activities of daily living (IADL) were applied to find Bayer-ADL correlations in 311 dementia outpatients that were ≥60 years old. The Iranian version Bayer-ADL scores between illiterate and literate dementia elderly, based on GDS, observed good discrimination values (0.923 sensitivity and 0.750 specificity) in illiterate people, and excellent discrimination values were achieved (sensitivity 0.919 and 0. 986 specificity) in literate dementia elderly. The suggested cutoff points were 1.79 for illiterate and for the Iranian literate dementia elderly 1.82, based on GDS. Both forms (24 and 25 items) of Bayer-ADL were correlated to GDS, ADL, and IADL. Bayer-ADL is a valid tool to distinguish physical dysfunction between illiterate and literate of the Iranian dementia elderly; however, some revisions in the components are needed for the illiterate elderly. Generally, the findings presented in the Iranian version Bayer-ADL could be useful to both clinical purpose and international studies.

Diagnostic accuracy of the Tilburg Frailty Indicator (TFI) for early frailty detection in elderly people in Iran.

AIM: Screening is one of the most important ways for early frailty detection that contributes to its prevention and timely treatment. The aim of this study was to determine the diagnostic value of the Persian version of the Tilburg Frailty Indicator (P-TFI) in the frailty screening. METHOD: This is a diagnostic test accuracy study that uses known group method. It was designed based on a STARD statement and performed on 175 elderly people in the City of Kashan, Iran. The subjects were selected among older people available in health centers affiliated to Kashan University of Medical Sciences using purposive sampling. Data analysis was carried out using SPSS v16. Descriptive statistics were used to describe the characteristics of the research subjects. Independent t-test was used to determine the ability of the P-TFI to discriminate frail and non-frail individuals, and to evaluate the cut-off point and instrument accuracy, the receiver operating characteristic (ROC) curve was used. The best cut-off point was determined among the proposed points using Youden index. At the determined cut-off point, the diagnostic value parameters of the P-TFI (sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, accuracy, and diagnostic odds ratio) were calculated and their range was estimated with 95 % confidence interval. FINDINGS: A total of 74.3 % of the sample was male and their mean age was 68.6 ± 54.44 years. The area under the ROC curve was calculated 0.922, indicating high accuracy of the instrument. The sensitivity and specificity of this instrument at the cut-off point of 4.5 were 0.95 and 0.86, respectively. Positive and negative predictive values were calculated 0.68 and 0.98, respectively, and the accuracy of the instrument was reported to be 0.88. CONCLUSION: The P-TFI can be used as a sensitive and accurate instrument, which is highly applicable to screen frailty in older people.

The prevalence and predictors of diabetes distress in elderly with type 2 diabetes mellitus.

AIMS: Diabetes distress (DD) leads to damaging consequences in patients with type 2 diabetes mellitus (T2DM). Few studies have been carried out on the DD among elderly in Iran. The aim of the current study was to investigate the prevalence of DD and some of its related factors on the elderly living in Qom, Iran. METHODS: This study was cross-sectional, in design. It lasted for three months (December to February 2018). 519 community dwelling(aged 60 and over) participated in the study. Participants' distress measured by diabetes distress scale (DDS). The cut of 3(≥3) was considered as the presence of distress. In addition, socio-demographic information was assessed. In order to determine predictors factors of DD, the logistic regression analysis was applied. RESULTS: The mean age (±SD) of the participants was 68.38 (SD:6.78) with the majority being female (53.6%). Among them, 48.6% were identified with DD. A multi-variable logistic regression analysis showed that being female (OR = 1.94, [ 1.30-2.31]), sedentary lifestyle (OR = 3.59, [1.43-9.03]), complications (OR = 3.10, [2.06-4.67]), body mass index (BMI) of 25 or more (OR = 2.46, [1.54-3.94]), duration of disease below 10 years (OR = 2.60, [ 1.56-4.31]), two comorbidity (OR = 2.07, [ 1.19-3.61]) and three or more comorbidity (OR = 3.51, [ 1.20-10.27]) are the predictors of DD. CONCLUSIONS: DD is notably prevalent among the elderly with T2DM. Attention to psychological aspects of diabetes is a health priority, especially among women and other high-risk groups.
