Trends in prevalence, mortality, and risk factors of dementia among the oldest-old adults in the United States: the role of the obesity epidemic. GeroScience 2024; 46:4761-4778. [PMID: 38696055 PMCID: PMC11336039 DOI: 10.1007/s11357-024-01180-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Accepted: 04/25/2024] [Indexed: 08/22/2024] Open
Abstract
The oldest-old population, those aged ≥ 80 years, is the fastest-growing group in the United States (US), grappling with an increasingly heavy burden of dementia. We aimed to dissect the trends in dementia prevalence, mortality, and risk factors, and predict future levels among this demographic. Leveraging data from the Global Burden of Disease Study 2019, we examined the trends in dementia prevalence, mortality, and risk factors (with a particular focus on body mass index, BMI) for US oldest-old adults. Through decomposition analysis, we identified key population-level contributors to these trends. Predictive modeling was employed to estimate future prevalence and mortality levels over the next decade. Between 1990 and 2019, the number of dementia cases and deaths among the oldest-old in the US increased by approximately 1.37 million and 60,000 respectively. The population growth and aging were highlighted as the primary drivers of this increase. High BMI emerged as a growing risk factor. Females showed a disproportionately higher dementia burden, characterized by a unique risk factor profile, including BMI. Predictions for 2030 anticipate nearly 4 million dementia cases and 160,000 related deaths, with a marked increase in prevalence and mortality anticipated among those aged 80-89. The past 30 years have witnessed a notable rise in both the prevalence and mortality of dementia among the oldest-old in the US, accompanied by a significant shift in risk factors, with obesity taking a forefront position. Targeted age and sex-specific public health strategies that address obesity control are needed to mitigate the dementia burden effectively.

Abstract
BACKGROUND To the creation of mutual aid relationships among people with cognitive decline is important in aging societies. This study aimed to develop and examine the feasibility of a GO Program in which older adults, with experience in playing GO, support the learning of GO by older adults with cognitive decline and other barriers to social participation, which in turn reduces social isolation and creates opportunities for older adults to use their role. METHODS This single-arm intervention study was conducted in Tokyo, Japan. Introductory GO classes were held for 10 participants who had never played GO (beginners) and 10 participants who had (supporters) once a week for an hour, for a total of 12 sessions. Supporters and beginners were paired to solve problems and play games. We assessed the feasibility of the program and its effects on mental health social network, and cognitive function. RESULTS Cognitive test scores were at the mild cognitive Impairment level for beginners as well as for supporters. Satisfaction with the program was high, with an overall class attendance rate of 99.1% and none leaving the program. No significant changes were observed over time for beginners in each measurement; however, there was a significant improvement in the Mini Mental State Examination-Japanese scores for supporters (p < .05). CONCLUSIONS The results suggest that this program could contribute to the creation of mutual aid relationships among older adults with cognitive decline; even if they have mildly declined cognitive function, they can still play an active role in society. Moreover, creating such opportunities may positively impact cognitive function.

Abstract
COVID-19 pandemic-related traumatic stress (PRTS) symptoms are reported in various populations, but risk factors in older adults with chronic medical conditions, remain understudied. We therefore examined correlates and pre-pandemic predictors of PRTS in older adults with hypertension during COVID-19. Participants in California, aged 61-92 years (n = 95), participated in a pre-pandemic healthy aging trial and later completed a COVID-19 assessment (May to September 2020). Those experiencing ⩾1 PRTS symptom (n = 40), and those without PRTS symptoms (n = 55), were compared. The PRTS+ group had poorer mental and general health and greater impairment in instrumental activities of daily living. Pre-pandemic biomarkers of vascular inflammation did not predict increased odds of PRTS; however, greater pre-pandemic anxiety and female gender did predict PRTS during COVID-19. Our findings highlight PRTS as a threat to healthy aging in older adults with hypertension; targeted approaches are needed to mitigate this burden, particularly for females and those with pre-existing anxiety.
