Depression among the oldest old: the Umeå 85+ study.

OBJECTIVES: To investigate the prevalence of depression among the oldest old and to analyze factors associated with depression. METHODS: A cross-sectional, population-based study was undertaken in Umeå, Sweden. Out of 319 eligible participants aged 85, 90 and 95 years and older, it was possible to evaluate 242 people (75.9%) for depression. Data were collected from structured interviews and assessments in the participants' homes, and from medical charts, relatives and caregivers. Depression was screened for using the Geriatric Depression Scale-15 and further assessed with the Montgomery-Asberg Depression Rating Scale. Cognition was assessed using the Mini-mental State Examination, activities of daily living (ADL) using the Barthel ADL Index, nutrition using the Mini Nutritional Assessment and well-being using the Philadelphia Geriatric Center Morale Scale. RESULTS: The 85-year-olds had a significantly lower prevalence of depression than the 90- and 95-year-olds (16.8% vs. 34.1% and 32.3%). No sex differences were found. One-third of those with depression had no treatment and among those with ongoing treatment 59% were still depressed. Persons diagnosed with depression had a poorer well-being and a higher 1-year mortality. Logistic regression analyses showed that depression was independently associated with living in institutions and number of medications. CONCLUSION: Depression among the oldest old is common, underdiagnosed and inadequately treated, and causes poor well-being and increased mortality. More knowledge about depression is essential to improve the assessment and treatment of depression among the oldest old.

Morale in the oldest old: the Umeå 85+ study.

OBJECTIVE: to describe morale among the oldest old, and to investigate which social, functional and medical factors are associated with morale in this population. DESIGN: a cross-sectional study. SETTING: a population-based study in the municipality of Umeå, a city in Northern Sweden. SUBJECTS: half of the 85-year-old population, and the total population of 90-year-olds and > or = 95-year-olds (95-103) were asked to participate (n = 319) and 238 were interviewed. METHODS: structured interviews and assessments during home visits, interviews with relatives and caregivers and review of medical charts. The 17-item Philadelphia Geriatric Center Morale Scale (PGCMS) was used to measure morale. Participants were assessed with the Barthel Activities of Daily Living (ADL) Index, Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), Mini Nutritional Assessment (MNA), and a symptom questionnaire. Multiple regression analyses were conducted to find independent factors to explain the variation in the PGCMS score. RESULTS: eighty-four per cent (n = 199) of those interviewed answered the PGCMS. Three-quarters had middle range or high morale. GDS score, type of housing, previous stroke, loneliness and number of symptoms, adjusted for age group and sex, explained 49.3% of the variance of total PGCMS score. CONCLUSIONS: a large proportion of the oldest old had high morale. The most important factors for high morale were the absence of depressive symptoms, living in ordinary housing, having previously had a stroke and yet still living in ordinary housing, not feeling lonely and low number of symptoms. The PGCMS seems applicable in the evaluation of morale among the oldest old.
