Therapeutic Effects of Low-Level Laser Therapy on Cognitive Symptoms of Patients with Dementia: A Double-Blinded Randomized Clinical Trial.

Objective: To investigate the effects of low-level laser therapy (LLLT) as a new nonpharmaceutical approach to improve cognitive symptoms in patients with dementia. Background: Routine pharmacological treatment of dementia patients is inefficient and has considerable adverse effects. Recent attempts to develop nonpharmaceutical approaches are considered favorable for patients with dementia. Methods: Thirty-two patients with dementia were randomly divided into the same population of LLLT and sham groups. The LLLT group underwent transcranial LLLT, and the sham group received the same protocol with a zero-intensity laser. All patients in the two groups were evaluated using the minimental state examination (MMSE) and clinical dementia rating (CDR) tests at the time of admission as baseline at 2 and 6 weeks postintervention. Results: The rate of change of MMSE scores in sham and LLLT groups was 0.13 ± 0.96 and 2.31 ± 1.81 in week 2 (p = 0.00005) and also -0.25 ± 0.86 and 2.53 ± 1.73 in week 8 (p = 0.000003). In the LLLT group, the mean scores of CDR were 1.28 ± 0.71, 1.28 ± 0.71, and 1.25 ± 0.80 at baseline, week 2, and week 8 (p = 0.605 and p = 0.742), respectively. The mean scores of CDR in the sham group were 1.69 ± 0.73, 1.75 ± 0.68, and 1.72 ± 0.82 at baseline, week 2, and week 8, respectively. Conclusions: These findings suggest that laser therapy could be a promising treatment modality and an adjunct to pharmacotherapy in dementia patients. Clinical Trial Registration: IRCT20191018045148N1 was obtained from the Iranian Registry of Clinical Trials (IRCT.ir).

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.

Domestic elder abuse and associated factors in elderly women in Tehran, Iran.

OBJECTIVES: Elderly people are often abused in many ways, with serious and lasting consequences. Elder abuse remains one of the most hidden forms of family conflict, and its frequency is anticipated to be rising in many countries that are rapidly experiencing population aging. The purpose of this study was to investigate the status of domestic elder abuse in elderly women in Tehran, Iran and to identify associated factors. METHODS: This cross-sectional study was conducted in 2017 among 260 women aged 60 and over, selected through multistage random sampling. Information on abuse and its risk factors was collected through interviews with the elderly in their homes. In order to measure domestic elder abuse, the validated Domestic Elderly Abuse Questionnaire was used. The ordinal logistic test was used in Stata version 12 to identify factors related to elder abuse. RESULTS: Overall, 90.4% of the subjects had experienced at least 1 type of abuse, among which authority deprivation (68.5%) was the most common and rejection (11.2%) the least common. The ordinal logistic analysis showed that the likelihood of experiencing more severe severe abuse was significantly higher in elderly people over 72 than in those aged 60-62 years (odds ratio, 2.07; 95% confidence interval, 1.03 to 4.17). CONCLUSIONS: Domestic elder abuse was found to be common in older women. Old age was an important risk factor for domestic elder abuse in elderly women in Tehran. Managing and preventing elder abuse is an important issue that needs to be addressed.

Validity and Reliability of Health Promoting Lifestyle Profile II in the Iranian Elderly.

BACKGROUND: With increasing age, the prevalence of chronic diseases increases. Since health-promoting behaviors (HPB) are considered a basic way of preventing diseases, especially chronic diseases, it is important to assess HPB. This study examines the validity and reliability of the Health Promoting Lifestyle Profile II (HPLP-II). METHODS: This is a cross-sectional study which is conducted on 502 elderly individuals aged 60 and over in Tehran, Iran. In order to determine the validity, content and construct validity were used. The content validity index (CVI) was used to assess the content validity and to assess construct validity, confirmatory factor analysis (CFA), and item-total correlations were employed. For reliability, test-retest analysis was used, and the internal consistency of the HPLP-II was confirmed by Cronbach's alpha. For data analysis, SPSS-18 and Amos-7 software was used. RESULTS: The mean age of the subjects was 66.3 ± 5.3 years. The CVI for the revised HPLP-II and all its subscales was higher than 0.82. The CFA confirmed a six-factor model aligned with the original HPLP-II. Pearson correlation coefficients between the revised HPLP-II and their items were in range of 0.27-0.65. Cronbach's alpha of the revised HPLP-II was obtained as 0.78 and for their subscales were in the range of 0.67-0.84. Intraclass correlation coefficient was obtained 0.79 (95% confidence interval: 0.59-0.86, P < 0.001). CONCLUSIONS: The Iranian HPLP-II scale is an appropriate tool for assessing HPBs of the Iranian elderly.

Socio-demographic risk factors of mobility dysfunction and limitations in physical functioning disability among the elderly in Iran: A nationwide cross sectional survey.

OBJECTIVE: To examine self-reported mobility and limitation in physical functioning among the elderly and associated socio-demographic risk factors. METHODS: The population-based cross-sectional study was conducted from January 2012 to January 2013 and comprised subjects from five provinces of Iran. The variables were measured using a questionnaire. Self-reported mobility disability and physical functioning disability were defined as having no problems in daily activities and physical tasks. Logistic regression was used to calculate the odds ratio for association of socio-demographic risk factors and outcomes. RESULTS: Of the 1325 subjects, 636(48%) were men. The overall mean age was 69.14±7.37 years. Prevalence of mobility disability and limitation in physical functioning was 401(63%) and 553(87%) in men, and 524(76%) and 641(93%) in women. There was a significant association between mobility disability and family composition and satisfaction with financial situation and housing tenure in both genders (p<0.05 each). Physical functioning had a significant relationship with family composition, and satisfaction with financial situations and housing tenure in men and women and population density in men and marital status in women (p<0.05 each). CONCLUSIONS: The elderly had a high risk of disability. Social factors had more association with mobility disability and limitation in physical functioning and required specific social support.

The health status of the elderly population of Iran in 2012.

BACKGROUND: With advancing age comes dramatic increase in the incidence of chronic diseases, disabilities, and mental problems. This study was conducted to epidemiologically describe the health status of the elderly population of Iran. MATERIAL AND METHODS: People aged ≥60 were selected. Mini-nutritional assessment, activity of daily living, geriatric depression scale questionnaires were administered. Physical diseases and risk factors were also investigated. For the purpose of this study, 1350 elderly individuals were randomly selected. RESULTS: The mean age of sample was 69.1±7.3 and 65.9% were illiterate. From total, 727 (53.8%) had vision problems. The most common problem was cataracts with a prevalence of 305 (22.6%) patients who were either suffering from cataracts or had undergone a surgery for it. From 634 individuals who used dentures, 446 (70.3%) wore the same first denture for over 10 years, without being examined. 524 (38.8%) of our seniors spent their free time alone at home. 13.2% of women and 12.6% of men were dependent on others for at least one daily activity. In terms of nutrition, 70 (5.5%) of the elderly (46 women and 24 men) were severely malnourished with 554 (41.3%) (243 men and 311 women) at risk of malnutrition. CONCLUSION: The health status of the elderly in Iran was similar to other countries in the world. However there continues to be room for improvement. Taking into account the rapidly aging population of Iran, health providers, and policy makers are required to take steps at a national level and direct more resources into supporting the elderly population.
