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 Persian Version of the "Life Satisfaction Scale": Construct Validity and Test-Re-Test Reliability among Iranian Older Adults.

After forward-backward translation, the LSS was administered to 334 Persian speaking, cognitively healthy elderly aged 60 years and over recruited through convenience sampling. To analyze the validity of the model's constructs and the relationships between the constructs, a confirmatory factor analysis followed by PLS analysis was performed. The Construct validity was further investigated by calculating the correlations between the LSS and the "Short Form Health Survey" (SF-36) subscales measuring similar and dissimilar constructs. The LSS was re-administered to 50 participants a month later to assess the reliability. For the eight-factor model of the life satisfaction construct, adequate goodness of fit between the hypothesized model and the model derived from the sample data was attained (positive and statistically significant beta coefficients, good R-squares and acceptable GoF). Construct validity was supported by convergent and discriminant validity, and correlations between the LSS and SF-36 subscales. Minimum Intraclass Correlation Coefficient level of 0.60 was exceeded by all subscales. Minimum level of reliability indices (Cronbach's α, composite reliability and indicator reliability) was exceeded by all subscales. The Persian-version of the Life Satisfaction Scale is a reliable and valid instrument, with psychometric properties which are consistent with the original version.

The effects of low dose n-3 fatty acids on serum lipid profiles and insulin resistance of the elderly: a randomized controlled clinical trial.

INTRODUCTION: N-3 fatty acids have several beneficial effects on dyslipidemia and diabetes, conditions which are prevalent in the elderly. This study assessed the effects of low-dose n-3 fatty acids on serum lipid profile, lipoprotein(a), apolipoprotein B, fasting glucose, insulin, and insulin resistance in a group of elderly Iranians. MATERIALS AND METHODS: A 6-month randomized, double-blind placebo-controlled clinical trial was carried out in 124 elderly residents of Kahrizak Charity Foundation aged >or= 65. The intervention group was supplemented with 1 g/day fish oil capsule (with 180 mg eicosapentaenoic acid, EPA; and 120 mg docosahexaenoic acid, DHA; a total of 300 mg n-3 fatty acids as effective constituents). Fasting blood samples were collected at baseline and after 6 months of the trial. RESULTS: There were no significant effects of fish oil on the studied variables in the intervention group. In the placebo group, serum triglyceride significantly increased and high-density lipoprotein cholesterol significantly decreased (p = 0.01 and p = 0.009, respectively). By repeated measurement analysis after adjustments, the overall decrease in serum triglycerides compared with placebo was significant (p = 0.04). CONCLUSION: Supplementation with low dose n-3 fatty acids for 6 months could significantly protect elderly Iranians from a rise in serum triglycerides.

Prescription pattern among Iranian community dwelling older adults.

Aim To assess prescription pattern among Iranian communitydwelling older adults. Methods This cross-sectional study employed a cluster random sampling to obtain a sample of 1591 patients aged 60 years and over referred to pharmacies in Tehran, 2017. Data were collected using a questionnaire: socio-demographic characteristics, type of pharmacy visited, the municipal district, the university covering the pharmacy, the number and names of prescribed drugs, drug category, type of insurances and physician's socio-demographic profile (age, gender, type of specialization, and work experience). Results The mean age of the patients was 70.51±7.84. A total of 5838 drugs were prescribed, giving an average of 3.73±2.24 drugs per patient (ranging of 1-15). Polypharmacy was noticed in 32.4% patients. Cardiovascular drugs accounted for 20.8% of the prescriptions, antidiabetics 8.8%, nutritional agents and vitamins 7.6%, and analgesics, anti-inflammatory drugs and antipyretics accounted for 7.5%. Conclusion Developing educational programs on geriatric pharmacology general practitioners and more supervision among community-dwelling older adults might have effects on prescription pattern. There is a need for prescriber training and retraining with emphasis on the geriatric population.

Prevalence and associated factors of potentially inappropriate medications among Iranian older adults.

Aim Potentially inappropriate medications (PIMs) in older people are associated with the increased use of health care services. The aim of this study was to investigate the prevalence of PIMs among the elderly being referred to pharmacies in Tehran using the Beers criteria of 2012, and identify factors related to PIMs. Methods This cross-sectional study was conducted on elderly patients (60 years and above) referred to pharmacies in Tehran, in 2017. The Beers' criteria 2012 were used to evaluate PIMs. The logistic regression analysis was used to find sociodemographic predictors of PIMs. Results The mean age of 1591 patients was 70.51 years. The overall prevalence of PIMs was 26.0%. The most frequent PIMs, in order of frequency, included diclofenac (13.5%), alprazolam (9.3%), and chlordiazepoxide (9.1%) and clonazepam (8.4%). The pain medications were found to be most common PIMs (37.6%). Polypharmacy (OR=3.64, CI 95%: .81-4.70; p<0.001), number of chronic disease (OR=2.371, CI 95%:1.71-3.28; p<0.001) insomnia (OR=1.45, CI 95%: 1.13-1.87; p<0.01) and type of specialists were found as PIMs risk factors. Internal medicine specialists prescribed PIMs significantly fewer times than other specialists(OR=0.59, CI 95%: 0.40-0.88; p<0.01, and the orthopedic specialists prescribed PIMs significantly more times than other physicians (OR=3.23, CI 95%: 5.76-1.81; p<0.001). Conclusion High prevalence of PIMs among Iranian elderly patients implies a need for the development and operationalization of scientific guidelines for the use of medicines. It is also necessary to hold training courses for physicians to be educated in such cases.

Self care behaviors among elderly with chronic heart failure and related factors.

Self Care Behaviors (SCB) is one of the most important challenges in controlling readmission and improving the elderly patients outcomes. The aims of this study were to describe the SCB among elderly with heart failure and to assess relationships between SCB, demographic characteristics, age-related characteristics and clinical characteristics. In this cross sectional study, 184 elderly (age 60) with heart failure were selected with convenience sampling from 4 teaching hospitals. To assess SCB, the European Heart Failure Self Care Behavior Scale was used. Its validity and reliability were confirmed (CVI = 0.97 and α = 0.74). Data was collected from patients' medical record and by interviews. The highest percentage of behaviors not performing properly (score > 2), were related to self reported exercise (96.2%), receiving a flu shot (89.7%) and weight monitoring (80.5%), respectively. There was significant relationship between SCB and cognitive impairment (p < 0.001), serum sodium level (p < 0.001), charlson co-morbidity Index (p = 0.001), ejection fraction (p = 0.002), visual impairment (p = 0.002), sleep disorders (p = 0.003), poly-pharmacy (p = 0.004), hearing impairment (p = 0.012) and systolic blood pressure (p = 0.049). Significant relationship between SCB and age-related characteristics suggests the need to design both supportive and preventive programs among elderly with heart failure.
