Abstract Background Biologic studies have suggested that tea may have neuroprotective activity. However, tea’s protective effect on cognitive function is controversial in human epidemiological studies, and no data, including the middle-aged, are available. The objective of this study was to investigate the association of habit, frequency, and types of tea consumption with incident cognitive impairment in middle-aged and older adults. Methods Data from the Asymptomatic Polyvascular Abnormalities in Community study were used (aged over 40y). We gathered information on tea consumption, including habit, frequency, and types, via a standardized questionnaire and assessed cognitive function by Mini-Mental State Examination (MMSE) and/or Montreal Cognitive Assessment (MoCA). Three thousand eight hundred sixty-eight and 806 participants were selected in MMSE and MoCA subgroups. Multivariate logistic regression models were utilized to examine associations between tea consumption and cognitive impairment in middle-aged and older participants. Results In MMSE analyses, after adjustment for potential confounding factors, habitual (odds ratio (OR) 0.47, [95% confidence interval (CI) 0.33–0.68], p < 0.001) and high frequency (p trend < 0.001) of tea intake were associated with a lower risk of cognitive impairment. The risk of cognitive impairment was lower in green tea consumption (OR 0.36, [95% CI 0.22–0.61], p < 0.001) than other types (OR 0.59, [95% CI 0.38–0.91], p = 0.017). In MoCA analyses, we got similar results. Conclusions Habitual tea consumption, especially high-frequency and green tea consumption, was significantly associated with a lower prevalence of cognitive impairment in middle-aged and older individuals.

Abstract Objectives This paper examines the association between cognitive impairment, including mild cognitive impairment (MCI) and early dementia (ED), and sexual activity in a large, longitudinal sample of community-dwelling older adults. We focus here on sexual activity, which includes both sexual activity with a partner and masturbation. Methods We analyzed 3777 older individuals and members of 955 intimate dyads using the National Social Life, Health and Aging Project (2010 and 2015). We used ordered-probit regression, cross-lagged panels models, and probit regression. Results We find that older adults with cognitive limitations, either MCI or early dementia, are about as likely to be sexually active with a partner as those with normal cognitive function. This is the case both in the cross section and longitudinally. Both men and women with early dementia are less likely to have masturbated, however. Among married and cohabiting couples, we find no association between cognitive impairment in either the husband, the wife, or in both partners and their joint sexual activity. Women whose measured cognitive function is lower than their husband’s are less likely to report any masturbation. Discussion Sex with a partner, a fundamentally social activity, seems to be conserved in the face of cognitive limitation but masturbation, a solitary activity, does not. We argue that the intimate dyad plays an important role in conserving partnered sexual activity. Results can inform strategies to maintain sexual well-being of older adults with cognitive impairment and their partners as part of overall strategies to improve quality of life.

BackgroundProspective studies suggest that tea consumption may decrease the risk for cognitive impairment in late life. However, little research has examined the association between tea consumption and cognitive performance across multiple domains. In addition, no research has examined the benefit of tea consumption on cognitive performance among older adults with existing impairment.AimsThe current study examined the association between tea consumption and performance on tasks of global cognitive function, episodic memory and executive function in cognitively healthy (CH) older adults and older adults with mild cognitive impairment (MCI).MethodsThe analytical sample included 1849 community-dwelling older adults from the Shanghai Brain Aging Study (65.6% female, mean age of 69.50 (8.02) years). Following ascertainment of cognitive function, 816 were categorised as MCI. In addition to completion of a demographics questionnaire, participants reported their tea consumption and completed a battery of tests to measure global cognitive function, episodic memory and working memory.ResultsIndependent analyses of covariance revealed a significant association between tea consumption and measures of episodic memory; however, these associations were restricted to CH older adults but not older adults with MCI. Tea consumption was not associated with working memory performance.ConclusionsThe current study suggests that the benefit of tea consumption is restricted to cognitively healthy older adults and does not extend to older adults with MCI.

Abstract Background To investigate the association between green tea consumption and the annual rate of change of gray matter (GM), white matter (WM), and hippocampal volumes in middle-aged and older Japanese community-dwellers. Methods A prospective cohort study with two years of follow-up was conducted with 1693 participants (aged 40–89 years). Green tea consumption (mL/day) data were collected with a 3-day dietary record. Volumes of GM, WM, and the hippocampus were estimated by T1-weighted brain magnetic resonance imaging and FreeSurfer software. The GM ratio, WM ratio, and hippocampal ratio (HR) were calculated as the percentages of total intracranial volume, respectively. Results The mean (SD) annual rate of change of hippocampal volume [(HR at baseline - HR at follow-up)/HR at baseline/follow-up years×100%] was 0.499 (1.128) (%). In the multivariable-adjusted general linear model, green tea consumption at baseline was negatively associated only with the annual rate of change of hippocampal volume (%) [β (95% CI) for each 1 mL/day increase in green tea consumption = -20.2E-5 (-35.0E-5 to -5.3E-5); P-value = 0.008]. No associations were observed for the annual rate of change of GM or WM volumes. The results remained significant when the analysis was limited to those with stable green tea consumption and were especially evident among individuals aged 65 years and older and among women. Conclusions In this study, each additional 100 mL/day of green tea intake was related to a reduction of approximately 5% in annual hippocampal atrophy. This association was especially evident among older individuals and among women. Key messages A negative association between green tea consumption and brain atrophy has been suggested; however, this relationship has not yet been investigated in humans. In this study, for the first time, a negative association between green tea consumption and annual hippocampal atrophy was observed in community-dwelling middle-aged and older individuals.

Community Dwelling Older Adults

This study examined the prevalence of cognitive impairment among older adults in central Vietnam and the roles of communication (with or without communication devices) in the association between cognitive impairment and hearing loss. This cross-sectional study was performed on 725 randomly selected community-dwelling older adults aged ≥60 years from Thua Thien Hue province, Vietnam. Participants attended a face-to-face survey. Sociodemographic characteristics, social interaction with or without communication devices, health status and cognitive function using the Mini-Mental State Examination were reported. Ordinal logistic regression analysis was performed to quantify the association between hearing loss and cognitive function by frequency of communication with and without devices. Mild and severe cognitive impairment had prevalence rates of 23.6% and 19.3%, respectively. Cognitive impairment was more prevalent among older adults with hearing-loss, vision loss and difficulties with instrumental activities of daily living (IADL). The association between hearing loss and cognitive impairment was not significant when older adults had frequent communication with others using devices. This study presented the relatively high prevalence of cognitive impairment in community-dwelling older adults in Vietnam. Frequent communication using devices attenuated the association between hearing loss and cognitive impairment.

The Impact

Background: Given the documented importance of employment for middle-aged and older adults’ mental health, studies of the association between their number of work hours and depressive symptoms are needed. Objectives: To examine the association between the number of work hours and depressive symptoms in Korean aged 45 and over. Methods: We used data from the first wave to fourth wave of the Korea Longitudinal Study of Aging. Using the first wave at baseline, data included 9845 individuals. Depressive symptoms were measured using the 10-item Center for Epidemiological Studies Depression scale. We performed a longitudinal analysis to estimate the prevalence of depressive symptoms by work hours. Results: Both unemployed males and females aged 45–65 years were associated with higher depressive symptoms (β = 0.59, p < 0.001; β = 0.32, p < 0.001). Females working ≥ 69 h were associated with higher depressive symptoms compared to those working 41–68 h (β = 0.25, p = 0.013). Among those both middle-aged and older adults, both males and females unemployed were associated with higher depressive symptoms. Those middle-aged female working ≥69 h were associated with higher depressive symptoms. Conclusions: An increase in depressive symptoms was associated with unemployed males and females working ≥69 h compared to those working 41–68 h. Although this association was found among middle-aged individuals, a decrease in depressive symptoms in both sexes was associated with working 1–40 h. Depressive symptoms should decrease by implementing employment policies and social services to encourage employers to support middle-aged and older adults in the workforce considering their sex and age differences.

Social Markers

Abstract Social relationships play an important role in cognitive health and aging. However, it is unclear how older adult’s cognitive function affects their everyday social interactions, especially for those with mild cognitive impairment (MCI). This study examined whether older adults with intact cognition vs. MCI differed in their daily social interactions. Community-dwelling older adults from the Einstein Aging Study (N=244, 70-91 yrs) reported their social interactions five times daily for 14 consecutive days using smartphones. Compared to those with normal cognitive function, older adults with MCI reported less frequent positive social interactions (p=0.012) and in-person social activities (p=0.006) on a daily basis. These two groups, however, did not show significant differences in their social relationships assessed by a conventional global questionnaire. The results support that, relative to global social relationships, daily social interactions are more sensitive, ecologically valid social markers that can facilitate the early detection of MCI.

Coronary Syndrome

Frailty is a marker of poor prognosis in older adults after acute coronary syndrome. We investigated whether cognitive impairment provides additional prognostic information. The study population consisted of a prospective cohort of 342 older (>65 years) adult survivors after acute coronary syndrome. Frailty (Fried score) and cognitive function (Pfeiffer’s Short Portable Mental Status Questionnaire—SPMSQ) were assessed at discharge. The endpoints were mortality or acute myocardial infarction at 8.7-year median follow-up. Patient distribution according to SPMSQ results was: no cognitive impairment (SPMSQ = 0 errors; n = 248, 73%), mild impairment (SPMSQ = 1–2 errors; n = 52, 15%), and moderate to severe impairment (SPMSQ ≥3 errors; n = 42, 12%). A total of 245 (72%) patients died or had an acute myocardial infarction, and 216 (63%) patients died. After adjustment for clinical data, comorbidities, and Fried score, the SPMSQ added prognostic value for death or myocardial infarction (per number of errors; HR = 1.11, 95%, CI 1.04–1.19, p = 0.002) and death (HR = 1.11, 95% 1.03–1.20, p = 0.007). An SPMSQ with ≥3 errors identified the highest risk subgroup. Geriatric conditions (SPSMQ and Fried score) explained 19% and 43% of the overall chi-square of the models for predicting death or myocardial infarction and death, respectively. Geriatric assessment after acute coronary syndrome should include both frailty and cognitive function. This is particularly important given that cognitive impairment without dementia can be subclinical and thus remain undetected.

Objective: This study examined the association between childhood conditions and cognitive function among middle-aged and older adults in China. Method: We analyzed data from the 2011 China Health and Retirement Longitudinal Study ( N = 11,868). Cognitive function was measured by word recall, a test of episodic memory. We examined the association between childhood conditions and cognitive function among the middle-aged (45-59 years) and the older (60 years and older) adults separately, using multilevel linear regressions. Results: Indicators of childhood socioeconomic status (SES) and nutrition were significantly associated with memory performance among the middle-aged and the older adults in China. Adulthood SES, education in particular, accounted for some but not all the associations. The protective effect of childhood urban residence was stronger for middle-aged women than for middle-aged men. Discussion: Childhood conditions are significantly associated with mid- to late-life cognitive function in China. The strengths of the associations may vary by gender and cohort.
