Thirty-day prevalence of delirium among very old people: A population-based study of very old people living at home and in institutions

Delirium has mainly been studied in various patient samples and in people living in institutions. The present study investigates the 30-day prevalence of delirium in a population-based sample of very old people in northern Sweden and Finland. Seven hundred and eight persons aged 85 years and older from the GErontological Regional DAtabase (GERDA) were assessed. Information was also collected from relatives, carers and medical records. Assessments performed were among others the Organic Brain Syndrome (OBS) scale, the Mini Mental State Examination (MMSE), and the Geriatric Depression Scale-15 (GDS-15). Delirium, depression and dementia diagnoses were based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. The prevalence of delirium was 17% among 85 year-olds, 21% among 90 year-olds and 39% among participants aged 95 years and older (p<0.001). Delirium prevalence among individuals without dementia was lower than among those with dementia (5% vs. 52%, p<0.001). Factors independently associated with delirium superimposed on dementia in a multivariate logistic regression model were depression (Odds Ratio (OR)=2.0, 95% Confidence Interval (CI)=1.2–3.3), heart failure (OR=2.1, 95% CI=1.2–3.7), institutional living (OR 4.4, 95% CI=2.4–8.2) and prescribed antipsychotics (OR=3.0, 95% CI=1.5–6.0).Delirium is highly prevalent among very old people with dementia. Depression, heart failure, institutional living and prescribed antipsychotic medication seem to be associated with delirium.

Conceptions and tendencies of age discrimination and attitudes towards older people in selected regions in Finland and Sweden

This study aims to access and explore tendencies in the conceptualization of age discrimination and the perceived attitudes towards older people in regions of Finland and Sweden. The analysis draws on GERDA survey data (GErontological Regional DAtabase), a repeated cross-sectional study in which data was collected in 2005 and 2010. The results indicate that the conceptions of age discrimination are changing in a positive direction, which is contrary to results shown in the Eurobarometer. On the basis of balance coefficients we show that conceived attitudes towards older people are changing as well, except for individuals in some sub-groups. We discuss the role of political rhetoric in relation to ageing awareness, the (non)individualization of society and the negotiation of age relations as tentative interpretations that strongly challenge the observed empirical tendencies.

Senior citizens and political participation – evidence from a Finnish regional study

ABSTRACTThe aim is to analyse political participation among senior citizens in the West-Finnish region Österbotten/Pohjanmaa by using data from the 2005 GERDA (gerontological regional database) survey. The first research question related to patterns of political participation and the extent to which older people in this region engage in voting and non-institutionalised forms of participation. Secondly, the driving forces behind different dimensions of participation were assessed on an individual level by using a modified variant of the civic voluntarism model as suggested by Verba and colleagues. The results show a high propensity to vote among elders in this region, but they also suggest that so-called non-institutionalised participation is likely to become more common in the future. Moreover, even though the results support the so-called resource theory of political participation, the fit of the multivariate models were modest, which necessitates further research in order to understand fully the driving forces behind political participation of older people in this specific region.
