Among older people with cognitive impairment and mild dementia, relatively little is known about the factors that predict preferences for everyday living activities and experiences and that influence the relative importance of those activities and experiences.

Cross-sectional study.

Participants were recruited from the Massachusetts Alzheimer’s Disease Research Center (MADRC) Clinical Core longitudinal cohort.

The sample included 62 community-dwelling older adults with cognitive impairment (Clinical Dementia Rating global score ≥ 0.5).

We used the Preferences for Everyday Living Inventory (PELI) to assess preferences for activities and lifestyle experiences among persons with cognitive impairment. Within-subjects analysis of variance was used to test for significant differences in the mean ratings of importance for four domains of the PELI (“autonomous choice,” “social engagement,” “personal growth,” and “keeping a routine”). Multiple regression models were used to relate predictors, including neuropsychiatric symptoms, to importance ratings for each domain.

Significant differences were noted in the mean importance ratings of the preferences domains: “social engagement” preferences were rated as most important, followed by “autonomous choice,” “personal growth,” and “keeping a routine.” For the “social engagement” preferences domain, female sex was significantly associated with higher importance of “social engagement,” while depressive symptoms (Geriatric Depression Scale-15 scores) were significantly associated with lower importance.

This study adds novel insight into the everyday preferences of community-dwelling older adults with cognitive impairment and highlights the impact of a number of factors, particularly level of depression, on how important various everyday experiences are perceived.

To investigate potential risk factors for mild behavioral impairment (MBI) among non-demented geriatrics.

Population-based, cross-sectional survey.

Taiwan Alzheimer Disease Association (TADA) Database.

Participants were selected by multistage random sampling of all Taiwan counties. They received in-person interviews between December 2011 and March 2013.

Demographic data, lifestyle and habits, medical comorbidities, cognitive status measured by the Taiwanese Mini-Mental Status Examination (TMSE) and presence of MCI of the participants were collected. Subjects were distributed to the MBI and non-MBI groups. These factors had been evaluated for their effects on MBI in the univariate and multivariable logistic regression models.

In total, 6,196 non-demented participants aged 65 years or older, including 409 MBI and 5,787 non-MBI participants, were recruited. After adjustment for age, sex, education, body mass index, lifestyle and habits, medical comorbidities, and MCI, good sleep was associated with lower risk of MBI (OR 0.09, 95% CI 0.07 – 0.12). Low body weight (OR 2.01, 95% CI 1.21–3.33), low-to-medium education (OR 1.40, 95%CI 1.06–1.85; OR 2.32, 95% CI 1.67–3.21), medical comorbidities of hypertension (OR 1.56, 95% CI 1.25–1.95), hyperlipidemia (OR 1.29, 95% CI 1.00–1.67), cancer (OR 2.05, 95% CI 1.37–3.06) were significantly associated with increased MBI risk. MCI neither increased nor decreased risk of MBI (OR 1.00, 95% CI 0.76–1.32).

Good sleep was associated with lower MBI risk. Underweight, lower education, medical comorbidities of cancer, hypertension, hyperlipidemia were predictive of MBI.
