Updated Understanding of the Experiences and Perceptions of Alcohol Use in Later Life.

The purpose of this study was to update our understandings of older adults' experiences and perceptions of alcohol use. Taking a community-based research approach, three Knowledge Café workshops hosted 66 older adults and service providers in Vancouver, BC. Thematic analysis identified three overarching categories: (a) reasons older adults use alcohol, including out of habit, social expectations, or to self-medicate; (b) personal experiences of alcohol use, including reduced consumption over time as a result of the cost of alcohol, the physical effects, and increased knowledge about the effects of alcohol; and (c) older adults' perceptions of alcohol use outcomes, including positive outcomes from drinking in moderation and negative outcomes that can worsen one's health, lead to tolerance, and harm others. Developing and promoting healthy drinking behaviours in later life is needed as the general population continues to age.

Engaging in Community Dialogues on Low-Risk Alcohol Use Guidelines for Older Adults.

Despite widespread use and acceptance of alcohol, discussions of age-related changes that impact alcohol consumption behaviors are rare. The objective of this community-engaged qualitative research study was to gain insight into how to promote knowledge dissemination regarding newly developed low-risk drinking guidelines for older adults. A convenience sample of 66 older adults and service providers participated in three Knowledge Café dialogue workshops and discussed their opinions about alcohol use in later life and ideas for sharing alcohol-related research evidence with the community. Participants discussed (a) low-risk drinking knowledge dissemination, (b) personal choice in drinking alcohol and adherence to low-risk drinking guidelines, and (c) preferences for engaging in discussions about alcohol use. Community dialogues fostered knowledge dissemination while participants engaged in rich conversations about a rarely discussed topic. Sharing evidence-based clinical advice with community stakeholders through dialogue events offers an innovative opportunity for health promotion efforts.

Psychological resilience predicts depressive symptoms among spouses of persons with Alzheimer disease over time.

This study examines the three facets of psychological resilience (i.e., perceived control, commitment to living, challenge versus stability) as predictors of depressive symptoms over time among spousal caregivers of persons with Alzheimer disease; these resilience factors were considered over and above dementia-related and socio-demographic control variables. A sample of 105 cohabiting spouses of persons diagnosed with probable or possible Alzheimer disease was recruited for this study. Multilevel modeling enabled us to examine baseline resilience, and the direction and magnitude of change in resilience over time, as distinct predictors of depressive symptoms one year later, and change in depressive symptoms between points of measurement. Both Time 1 control and challenge predicted lower levels of depressive symptoms one year later; furthermore, an increase in challenge over this interval predicted lower Time 2 depressive symptoms. In contrast, commitment did not emerge as a statistically significant predictor of caregiver depression. Findings of this study provide general support for the stress process model of caregiving; in particular, the central role of intra-psychic factors as significant predictors of depressive symptoms over time.

Involvement of ApoE E4 and H63D in sporadic Alzheimer's disease in a folate-supplemented Ontario population.

Dysregulation of iron homeostasis is implicated in Alzheimer's disease (AD). In this pilot study, common variants of the apolipoprotein E (APOE) and HFE genes resulting in the iron overload disorder of hereditary hemochromatosis (C282Y, H63D and S65C) were evaluated as factors in sporadic AD in an Ontario sample in which folic acid fortification has been mandatory since 1998. Laboratory studies also were done to search for genetic effects on blood markers of iron status, red cell folates and serum B12. Participants included 58 healthy volunteers (25 males, 33 females) and 54 patients with probable AD (20 males, 34 females). Statistical analyses were interpreted at the 95% confidence level. Contingency table and odds ratio analyses supported the hypothesis that in females of the given age range, E4 significantly predisposed to AD in the presence but not absence of H63D. In males, E4 significantly predisposed to AD in the absence of H63D, and H63D in the absence of E4 appeared protective against AD. Among E4+ AD patients, H63D was associated with significant lowering of red cell folate concentration, possibly as the result of excessive oxidative stress. However, folate levels in the lowest population quartile did not affect the risk of AD. A model is presented to explain the experimental findings.
