Cross-Cultural Adaptation of Gujarati Version of Rowland Universal Dementia Assessment Scale for Assessing Cognition in Elderly Population

Background: The Rowland Universal Dementia Assessment Scale (RUDAS) has less educational bias when compared to other cognitive assessment scales like MMSE and MoCA. But its performance has not been adequately addressed in Indian population. Moreover, there are very less scales for cognition which are available in Guajarati language which can be taken in elderly population. Therefore, the reliability and validity of Gujarati-RUDAS in elderly population needs to be tested. Purpose: To determine the reliability and validity of the translated Gujarati version of Rowland Universal Dementia Assessment Scale (RUDAS) for assessing cognition in elderly population. Methodology: A total of 60 subjects were included in this study according to the inclusion criteria. After gaining cross-cultural adaptations, reliability was assessed with intra-rater and inter-rater reliability, analyzed by intraclass correlation coefficient (ICC). Validity was assessed with content validity, analyzed by content validity index (CVI), Result: Intra-rater reliability was having good reliability with ICC value of 0.757 and inter-rater reliability was found to be moderately reliable with ICC value of 0.700. Content validity was found to be good with CVI of 1. Conclusion: The Gujarati version of RUDAS (G-RUDAS) is a reliable and valid tool for the screening of cognitive impairment among elderly population.

A study of quality of sleep, quality of life, and cognition in elderly: Healthy control, depressed and with mild neurocognitive disorder

Background: Sleep plays a vital role in maintaining optimum physical and mental functioning and can be implicated in affecting the quality of life (QOL) and cognition in elderly population. This study aims to assess quality of sleep, QOL and to assess the effect of quality of sleep on QOL and cognition in elderly population Materials and Methods: A cross-sectional study was done in elderly population in which 30 were healthy control, 30 depressed, and 30 with mild neurocognitive disorder (NCD) who were assessed using Pittsburg Sleep Quality Index, World Health Organization QOL (WHOQOL)-BREF, Geriatric Depression Scale-Short form, and Addenbrooke's Cognitive Examination Scale-Revised (ACE-R). Statistical analysis was done using SPSS 20 software using descriptive methods and Pearson's correlation test. Results: Mean Pittsburgh Sleep Quality Index (PSQI) score was the lowest and mean WHOQOL-BREF score highest in healthy control compared to elderly with mild NCD and depression, the difference being statistically significant in both cases (P < 0.01). PSQI scores have negative correlation with the ACE-R scores when studied in healthy control group (P < 0.05, r = −0.136) and WHOQOL-BREF domain scores overall (P < 0.01 r = −0.485, −0.497, −0.350, −0.475). Conclusion: Quality of sleep in elderly with depression and mild NCD is lower as compared to healthy control. Sleep may affect QOL and cognition in elderly and thus it would be essential to screen and identify sleep-related issues and intervene early.

3526 Healthy eating, physical activity, sleep and cognitive function in elderly population: Data from National Health and Nutrition Examination Survey 2011-2014

OBJECTIVES/SPECIFIC AIMS: To examine the relationship between healthy eating, physical activity (PA), sleep problem and hours of sleep and cognitive function among elderly population and the racial/ethnic differences in this relation. METHODS/STUDY POPULATION: We analyzed data from National Health and Nutrition Examination Survey 2014-2016 for 882 population 60 years and older. Cognitive status was measured by the Digit Symbol Substitution (DSS) exercise score and the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) total score. Healthy eating index (HEI), PA, and sleep problem and hours of sleep were assessed by questionnaire. The association between cognitive function and HEI, PA, sleep problem and hours of sleep were assessed by linear regression after adjusting for age, gender, race/ethnicity, poverty level, lipid profile, fasting glucose level, alcohol, body mass index, stroke and education. Data were analyzed using Stata 14 considering design and sample weight and p&lt;0.05 is statistically significant. RESULTS/ANTICIPATED RESULTS: CERAD total score was associated with HEI (Adjusted B = 0.07, 95% Confidence Interval (CI) = 0.01-0.13, p = 0.02) and not associated with physical activity or sleep problem or hours of sleep (p &gt; 0.05). Animal fluency score was associated only with HEI (Adjusted B = 0.05, 95% CI = 0.01-0.09, p = 0.02). DDS score was not associated with HEI, PA, or sleep problem (p &gt; 0.05) but associated with hours of sleep (p = 0.03). Stratified analysis by race/ethnicity showed that CERAD total score was associated with HEI only in White (Adjusted B = 0.08, 95% CI = 0.01-0.15, p = 0.02). DISCUSSION/SIGNIFICANCE OF IMPACT: CERAD total score was associated with HEI and not associated with PA or sleep problem. Promoting healthy eating is important for improving cognition in elderly population. Culturally sensitive and linguistically appropriate programs that involve community and care providers are needed to promote healthy eating for elderly population.

Influencia del ejercicio físico en la prevención del deterioro cognitivo en las personas mayores: revisión sistemática

In Spain, the number of elderly people is increasing, reason why the improvement in the attention given to the older adults has become a significant objective and requirement of health care systems. The physical activity is being recognized as a highly protective factor of the cognitive functions in aging, becoming a promising psycho-social strategy for the protection of the cognition in elderly population. PubMed, PsycINFO, Psicodoc, Scopus y SciELO sources were searched. We analyze the influence of the physical exercise in the prevention of the cognitive functions in healthy elderly and in the improvement or maintenance of the cognitive decline in older adults with early cognitive impairment. Thirty-one studies were selected and analysed. These studies indicated that a greater amount of physical activity is related with a decrease of cognitive decline in aging. The physical activity constitutes a promising psychosocial strategy for older adults with and without cognitive impairment. More experimental studies and homogeneity in the assessment instruments are needed. A deeper study of the convenience in the frequency and intensity of the interventions is also required.
