GSA 2019 Annual Scientific Meeting significant (F =23.64, p < .001) and explained 50.7% of the variance in FDM. Education and WAIS-III Arithmetic predicted FDM to a higher extent than financial literacy. Conclusions: The finding that education and fluid ability has a relatively higher impact on FDM as compared to crystallized ability is important. As one ages, fluid abil- ities decline more rapidly than crystallized abilities. This may be one explanation for why FDM ability worsens with age. To increase confidence in these findings, future research should test these models using age-stratified analyses. SUBJECTIVE MEMORY COMPLAINTS AND COGNITIVE PERFORMANCE: THE MODERATING ROLE OF DEPRESSIVE SYMPTOMS Elizabeth A. Gallagher 1 , 1. University of Massachusetts Boston, Boston, Massachusetts, United States Cognitive health is a rising public health concern in the U.S. Currently, approximately 5.7 million older adults suffer from Alzheimer’s disease (AD), and by the year 2050 this number is expected to increase to 14 mil- lion. Subjective memory complaints (SMC) are shown to be an early indicator of cognitive decline, and ac- cordingly included as a clinical criterion for diagnoses of MCI, an indicator of pre-dementia states, and a re- search criterion for AD diagnoses. Among older adults, depressive symptoms hinder the accuracy of memory self-ratings. However, there has yet to be consensus re- garding the nature of how depressive symptoms may condition the relationship between SMC and cognitive performance. The aims of the present study are to both investigate whether SMC is related to episodic memory and to determine whether depressive symptoms act as a moderator for the relationship between SMC and epi- sodic memory among older adults. This research used nationally representative sample of 8,123 older adults aged 65 and older who completed the Leave Behind Questionnaire in the 2012 and 2014 waves of the Health and Retirement Study. Linear regression was performed and results showed that there was a significant main ef- fect of SMC on episodic memory performance, in that older adults with increased SMC have worse episodic memory. There was also a significant moderating ef- fect of depressive symptoms, in that depressive symp- toms cause older adults to underestimate their memory abilities. In order to use SMC as a tool for early de- tection efforts it is critical to understand these complex relationships. PERFORMANCE ON COGNITIVE FUNCTIONING RELATED TO SUCCESSFUL AGING Neyda Ma. Mendoza Ruvalcaba, 1 Elva Dolores Arias Merino, 2 Maria Elena Flores Villavicencio, 3 and Melina Rodriguez Díaz 3 , 1.

University of Guadalajara CUCS, Guadalajara, Mexico, Mexico Introduction The cognitive functioning, as a general measure, is a criterion commonly used to defne and operationalize successful aging. (Project-Conacyt-256589) The aim of this study is to analyze cognitive function and its relationship with the successful aging in older adults. Methods Population based, random sample included n=401 community-dwelling older adults 60-years and older (mean age=72.51,SD=8.11 years,59.4% women). Cognitive func- tioning was assessed by a comprehensive battery including working memory(Digit Span Backward WAIS-IV), epi- sodic memory, metamemory(self-report), processing speed(Symbol Digit WAIS-IV), attention(TMT-A), ex- ecutive functioning(TMT-B), learning potential(RAVLT), language(FAS), visuospatial skills(Block Design WAIS-IV). Successful aging was operationalized in accordance with Rowe & Kahn defnition (no important disease, no dis- ability, physical functioning, cognitive functioning, and being actively engaged). Sociodemographic and health data were also asked. Data were analyzed in SPSSv24. Results In total 11.2% were successful agers and 11.4% had Mild Cognitive impairment. Global cognitive functioning was signifcantly related to the achievement of successful aging criteria. Specifcally, the more successful agers showed a sig- nifcant (p´s<.05) better performance on learning potential, working memory, metamemory, processing speed and at- tention. Executive functions were not related to successful aging criteria. None cognitive domain was related to the being actively engaged criteria. Better visuospatial skills were showed in older adults meeting the criteria of being free of disability and high physical functioning. Conclusion Knowledge generated by this study reveals the role of spe- cifc domains of cognitive functioning in successful aging, and sets a scenario to promote successful aging, through al- ternatives centered in the improvement of cognition in the older adults. COGNITION OLDER ADULTS WITH PREDIABETES EXPERIENCE ACCELERATED NEUROCOGNITIVE DECLINE Joyla Furlano, 1 and Lindsay Nagamatsu 1 , 1. Western University, London, Ontario, Canada Type II diabetes (T2D) is associated with neurocognitive decline beyond normative aging, and thus older adults with T2D are at high risk for developing dementia. However, the extent to which similar defcits occur in prediabetic older adults is not well understood. While few studies have shown that prediabetic older adults experience some cog- nitive decline, further research is needed to determine the specifc cognitive domains affected and the degree to which this decline occurs. Moreover, structural and functional brain changes that may occur with these defcits is cur- rently unknown in this population. Therefore, the aim of this study was to assess cognitive function and brain health in prediabetic older adults. We conducted a cross-sectional analysis of older adults (aged 60-80) with prediabetes (FPG 6.1-7.0 mmol/L) and healthy aged-matched controls, exam- ining 1) cognitive performance, 2) functional brain activa- tion as measured by fMRI, and 3) structural measures such as volume of the hippocampus. Based on our cross-sectional analysis, prediabetic older adults show impaired cognition (e.g., memory), as well as decreased hippocampal volume and activation. Therefore, we conclude that older adults 654 Innovation in Aging, 2019, Vol. 3, No. S1 Downloaded from https://academic.oup.com/innovateage/article/3/Supplement_1/S654/5616954 by guest on 05 March 2022
