Objective: This study aimed to identify predictors of 6-month physical function and 12-month relocation or death in 272 residents of 34 residential care/assisted communities. Method: Measures collected at baseline, 6, and 12 months included health and demographic characteristics; self-reported pain, fatigue, and depressive symptoms; exercise self-efficacy, barriers, and expectations; attitudes on aging; performance-based physical function and physical activity; and community demographics, programs, and policies. GLIMMIX procedures for regression analyses with community as a random effect were run. Results: Better baseline physical function and grip strength, female sex, and residential care community predicted better 6-month physical function. At 12 months, 25.6% had relocated or died. The odds of 12-month relocation or death for 1-point increase in physical function score was 0.84 and for 1-point increase in depression score was 1.16. Discussion: Targets to promote longer tenure in residential care/assisted living include programs to ameliorate functional decline and depression screening and treatment.

Objective: To examine differences between White and African American caregivers in strain, health, and service use in a population-based sample of informal caregivers for older adults. We also assessed whether relationship type (parent, other family, friend) and dementia care status (yes or no) were moderators of any racial differences. Method: We examined 887 informal caregivers via covariate-adjusted 3 × 2 × 2 factorial ANOVAs. Results: After covariate adjustment, there were few significant racial differences in caregiving strain, health, and service use. Dementia caregivers reported greater strain, and there were three-way interactions among relationship type, dementia care status, and race for physical strain and emotional stress. Discussion: Previous findings suggesting substantial racial differences in caregiver strain, which have primarily come from convenience samples that combined care relationship types, were not replicated. Racial and ethnic differences in caregiving may be context-specific. Historical changes in caregiving should be examined in future research.

Objective: Investigate direct and indirect associations between markers of socioeconomic position (SEP) across the life course and midlife cognitive ability while addressing methodological limitations in prior work. Method: Longitudinal data from the Danish Metropolit cohort of men born in 1953 (N = 2,479) who completed ability tests at age 12, 18, and 56-58 linked to register-based information on paternal occupational class, educational attainment, and occupational level. Associations were assessed using structural equation models, and different models were estimated to examine the importance of accounting for childhood ability and measurement error. Results: Associations between adult SEP measures and midlife ability decreased significantly when adjusting for childhood ability and measurement error. The association between childhood and midlife ability was by far the strongest. Discussion: The impact of adult SEP on later life ability may be exaggerated when not accounting for the stability of individual differences in cognitive ability and measurement error in test scores.

Objective: This study aims to examine the relationship between different levels of cognitive impairment (CI) and the frequency of hospital admission (HA). Method: Data from the National Health and Aging Trend Study, Round 1 (2011), with 8,245 respondents from Medicare beneficiaries were used. The data account for the number of hospital admissions for one year before the data collection. Clock Drawing Test and delayed word recall were employed to measure CI. Results: The severity of CI is one of the factors significantly associated with HA. Controlling for the level of function, the likelihood of HA increased among respondents with moderate, mild-to-moderate, and mild CI. Counterintuitively, HA was reduced when CI is severe. Discussion: People with CI are at more risk of frequent HA and the severity of impairment can increase this risk subsequently. Screening for CI at admission can open up the possibility of interventions, hence reducing complications during and after hospitalization.

Objectives: To compare the risk of insomnia symptoms among community-dwelling older adults who participated and did not participate in organized social activity and physical exercise. Design: Secondary data analysis of a prospective cohort study. Material and Methods: Community-dwelling older adults ≥65 years of age with no insomnia symptoms at baseline were included in the study. Participants were followed up yearly for 3 years. Insomnia symptoms, social activity, and physical exercise status of study participants were assessed at baseline and during follow-up. Results: Study participants who reported engaging in organized social activity and low-intensity physical exercise and organized social activity and high-intensity physical exercise were less likely to report insomnia symptoms during follow-up compared with those who did not engage in any activity. Conclusion: These results suggest beneficial effect of organized social activity and physical exercise in maintaining sleep quality in old age.

Objective: To develop an assessment method of active aging for research on older people. Method: A multiphase process that included drafting by an expert panel, a pilot study for item analysis and scale validity, a feedback study with focus groups and questionnaire respondents, and a test–retest study. Altogether 235 people aged 60 to 94 years provided responses and/or feedback. Results: We developed a 17-item University of Jyvaskyla Active Aging Scale with four aspects in each item (goals, ability, opportunity, and activity; range 0-272). The psychometric and item properties are good and the scale assesses a unidimensional latent construct of active aging. Discussion: Our scale assesses older people’s striving for well-being through activities pertaining to their goals, abilities, and opportunities. The University of Jyvaskyla Active Aging Scale provides a quantifiable measure of active aging that may be used in postal questionnaires or interviews in research and practice.

Objective: The aim of this study is to evaluate the relationship of leading causes of death with gradients of cognitive impairment and multimorbidity. Method: This is a population-based study using data from the linked 1992-2010 Health and Retirement Study and National Death Index (n = 9,691). Multimorbidity is defined as a combination of chronic conditions, functional limitations, and geriatric syndromes. Regression trees and Random Forest identified which combinations of multimorbidity associated with causes of death. Results: Multimorbidity is common in the study population. Heart disease is the leading cause in all groups, but with a larger percentage of deaths in the mild and moderate/severe cognitively impaired groups than among the noncognitively impaired. The different “paths” down the regression trees show that the distribution of causes of death changes with different combinations of multimorbidity. Discussion: Understanding the considerable heterogeneity in chronic conditions, functional limitations, geriatric syndromes, and causes of death among people with cognitive impairment can target care management and resource allocation.

Objective: This study examines difference in sexually transmitted disease (STD) prevalence between sexual minority and heterosexual older adults using lifetime experience of same-sex contact (SSC) as a measure of sexual orientation. Method: Data from the National Social Life, Health, and Aging Project (N = 2,519) are analyzed using negative binomial regression and propensity matching models to test for differences in average STD counts by sexual orientation. Results: Older adults who report any SSC have higher lifetime counts of STDs. This difference persists even when controlling for sex, race, education, age, military status, and incarceration. Propensity matching models show that this difference persists when respondents are matched on several factors that may influence SSC prior to STD contraction. Discussion: The present results call for greater attention from policy makers and researchers because the sexual orientation differences in STDs may exacerbate disparities in overall health status and quality of life.
