Abstract
Using the bivariate dual change score approach, the present study investigated the directionality of the SMC-OMP association in a sample of healthy older adults (N = 2,057) from the Virginia Cognitive Aging Project. The sample was assessed throughout 10 years, five time points, and the impact of education, depressive symptoms, and low-memory functioning was tested. The Memory Functioning Questionnaire was used to assess SMC. There was a lack of longitudinal association with no significant coupling effects found between subjective and objective memory. After including depressive symptoms as a covariate, Frequency of Forgetting significantly predicted subsequent negative changes in OMP . A similar result was found for the low-memory functioning group after the inclusion of depression, with the frequency of memory complaints predicting subsequent memory decline . Our results do not support a predictive value of SMC without accounting for the influence of depressive symptoms and low-memory functioning.

Abstract
OBJECTIVES Changes in memory can interfere with activities of daily living and may be indicative of serious health concerns such as mild cognitive impairment or dementia. Risk factors for cognitive decline and dementia have been shown to cluster around inequalities, suggesting that minority groups may be at an increased risk for cognitive decline. We sought to clarify the relationship between social determinants and change in memory function over a 3-year follow-up period, after accounting for demographic and health variables. METHODS We used baseline and first follow-up data from the Canadian Longitudinal Study on Aging (CLSA). Our primary analysis consisted of a multivariable linear regression model (n = 30,475). Demographic, health, education and occupation, social support, social identity, and social positioning variables (predictors) were measured at baseline. We computed a reliable change index (outcome) using the Rey Auditory Verbal Learning Test (RAVLT). RESULTS Older age and some health considerations (e.g., higher body mass index, low hearing) were associated with a greater decline in memory over the three-year period. In contrast, some physical activity and better self-rated general health were associated with improvements in memory. Having a hobby and better perceived social standing were associated with greater memory improvement. Social identities who experience minority stress (sexual orientation, gender identity, and race) did not predict change in memory. DISCUSSION Altogether, these results contribute to a growing body of evidence that points to older members of minoritized communities exhibiting initial differences in cognitive functioning (i.e., cross-sectional differences) but not more rapid cognitive aging.

Abstract
ObjectivesTo investigate how indicators of psychological stress and physical health differentially influence subjective and objective memory in older adults. Methods: 404 adults aged ≥55 without cognitive impairment participated in remote assessment of physical health (PHY; multimorbidity, body-mass-index), psychological distress (PDS; perceived stress, anxiety, depression), subjective memory complaints (SM), and task-based objective memory performance (OM). Results: Separately, both PHY and PDS significantly predicted SM (p < 0.01), but only PHY was associated with OM (p = 0.05). Combined models showed that PHY and PDS maintained significant association with SM (p < 0.01, R2 = 0.30), while only PHY was associated with OM (p = .07, R2 = 0.03; for associative OM, p = 0.04). Discussion: SM is associated with participants' psychological profile, highlighting the importance of addressing these factors when assessing SM. The results also reveal that remotely-administered OM tasks are more immune to participants' psychological profile, and support previously-established links between physical health and objective and subjective memory function.

Abstract
Objectives: The purpose of this study was to evaluate a cross-lagged panel model of general cognition and functional abilities over 13 years. The goal was to determine whether general cognitive abilities predict or precede functional decline versus functional abilities predicting cognitive decline. Methods: The sample included 3508 men (71-93 years of age at baseline) of the Kuakini Honolulu-Asia Aging Study who were tested repeatedly using a global cognitive test and an assessment of functional capacity. Education and age served as covariates. Cross-lagged models were tested, assessing stationarity of stability and cross-lags. Results: The overall model fit the data well. Cognitive scores had better stability than functional abilities and predicted functional abilities more strongly than functional abilities predicted cognitive scores over time. The strength of all cross-lags increased over time. Discussion: These longitudinal data show that cognitive scores predicted functional decline in a population-based study of older men.

Abstract
Background Nursing in military hospitals affects their general health. Educational interventions can help to maintain the general health of nurses. This study aimed to evaluate the effect of an educational intervention to improve the general health of nurses in military hospitals. Methods In this quasi-experimental study, 146 nurses working in military hospitals in Tehran, Iran in 2021 were included in the study. The one-month educational intervention included videos, pamphlets, and motivational messages about promoting general health. General health questionnaire with 28 items (GHQ28) was study tool. The allocation of nurses to groups was not random, it was based on personal interest. Frequency (percentage), and mean (standard deviation) were used to describe, and the chi-square test, Fisher’s exact test, independent and paired t-test were used for data analysis. All analyzes were performed in SPSS 24 software with a significance level of 5%. Results A total of 146 nurses participated in the study, most of them were in the age group of 30 to 40 years (64 people, 43.8%), and 76.7% (112 people) of them were women. The results of the independent sample t-test showed after the intervention, general health scores in the intervention group had a significant decrease compared to the control (p < 0.001) (change in intervention group = -31.1, V.S change in control = 0.55). The results of paired t-test showed that only in the intervention group, the value of the general health score and its dimensions were significantly different (p < 0.001). Conclusions The educational intervention performed well and decreased the score of the general health of military nurses. Given that these positive effects may be temporary, it is necessary to design and perform educational interventions over a longer period.

Abstract
OBJECTIVES The spousal relationship is one of the most important social contexts in old age, and the loss of a spouse/partner is associated with stress and cognitive decline. In the present study, we examined whether social relationships can buffer potential negative effects of spousal loss on cognition. We examined the role of social network, social activities, and perceived deficiencies in social relationships (loneliness). METHOD We used longitudinal data between 1998 and 2012 from 2,074 participants of the Health and Retirement Study, who had experienced spousal loss during the study period. Multilevel modeling was used to examine how time-varying indicators of social network, social activities, and loneliness were related to age-related trajectories of episodic memory prior to and after spousal loss. Analyses controlled for gender, race/ethnicity, education, time-varying functional health, and being repartnered/remarried. RESULTS Having children living within 10 miles and providing help to others buffered negative effects of widowhood on episodic memory. In addition, within-person increase in providing help to others buffered against decline in episodic memory after spousal loss. Having friends in the neighborhood, more frequent social visits, providing help to others, volunteering, and lack of loneliness were related to higher episodic memory, while having relatives in the neighborhood was related to lower episodic memory. DISCUSSION Our findings suggest that social networks, social activities, and loneliness are related to levels of cognitive function at the time of spousal loss and that social relationships can buffer negative effects of spousal loss on cognitive function. Implications for future research are discussed.

COVID-19 lockdowns' effects on the quality of life, perceived health and well-being of healthy elderly individuals: A longitudinal comparison of pre-lockdown and lockdown states of well-being. Arch Gerontol Geriatr 2021; 99:104606. [PMID: 34896795 PMCID: PMC8645291 DOI: 10.1016/j.archger.2021.104606] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 11/29/2021] [Accepted: 12/02/2021] [Indexed: 01/23/2023]
Abstract
Purpose . The concept of lockdown in relation to COVID-19 is thought to have an indirect impact on the quality of life and well-being of the elderly due to its consequences on the physical, psychological, and cognitive health of individuals. However, previous published studies on this subject are limited in terms of methodological approach used, including the absence of pre-confinement status and the type of experimental design, which is often cross-sectional. The present study proposes a longitudinal design with pre-confinement measures. It assesses changes in quality of life, perceived health, and well-being by comparing the period before lockdown (T1 = December 2019), three months after the start of the first lockdown (T2 = June 2020), and during the second lockdown (T3 = January 2021) due to COVID-19. Materials and Methods . This study is conducted with a group of 72 healthy elderly persons. They completed an electronic (online) survey assessing personal factors, activities, and participation as well as responding to the EuroQol-5D and Warwick-Edinburgh Mental Well-being Scale. Results . A decrease in quality of life, perceived health and well-being was observed between T1 and T2 and between T1 and T3, but no difference was reported between the two lockdown periods. The variables associated with these changes included energy level, level of happiness, physical activity, change in medical condition, memory difficulties, level of perceived isolation and age. Conclusion . This study will help to target variables that may have a deleterious effect on older adults for consideration in future confinement settings and for preventive purposes.

Abstract
The directionality of the longitudinal association between depressive symptoms and memory remains a topic of intense debate. A unidirectional association where depression impacts the change in memory (or vice-versa) and a bidirectional association where the trajectories of both dimensions affect each other lead to different clinical implications. METHOD This study investigated the depression-memory longitudinal association in a sample of 2057 older adults aged between 60 and 99 years old from the Virginia Cognitive Aging Project. The bivariate dual change score model was used to investigate the directionality of the association between episodic memory and three dimensions of depression (somatic symptoms, depressed affect, and positive affect) throughout ten years (five measurement points), controlling for education and sex. RESULTS the bidirectional model showed the best fit between somatic symptoms and memory, with a significant coupling effect observed from initial somatic symptoms to subsequent changes in memory. For depressed and positive affect, the unidirectional model with initial levels of depression predicting following changes in memory showed the best fit to the data, with significant coupling effects observed. Higher initial levels of somatic symptoms and depressed affect predicted a subsequent decline in memory, and higher initial levels of positive affect predicted subsequent better memory performance. Statistical adjustments for covariates (education and sex) had no significant influence on these associations. CONCLUSIONS Our findings support a unidirectional association with higher depressive symptoms preceding a steeper decline in memory in older adults. We discuss the clinical implications for depressive symptoms as a predictor of subsequent memory decline.
