Person-centered care as a tool to reduce behavioral and psychological symptoms in older adults with dementia living in residential care facilities

Among older adults living in dementia residential care facilities (RCF) behavioral and psychological symptoms (BPSD) are common, affecting the quality of life (QOL) for the residents as well as being challenging for the staff. The person-centered care (PCC) approach addresses BPSD by giving trained staff mandate to focus on the relation and to adapt the encounter and the environment to increase QoL for the person with dementia. The aims with this study were to improve PCC, decrease BPSD and improve QOL among older persons with dementia living in RCFs, and to explore leaders' and healthcare staff's experiences of a PCC intervention. An educational program was implemented at two RCFs. Data was collected through questionnaires, from national quality registries and through focus group interviews. A significant increase in PCC and QOL at three months was seen. However, no significant difference in BPSD was seen. The interviews showed the importance of a trust-based relationship, and support from an active management to improve PCC, as well as changing old patterns and recognising competence among staff. Factors that affect implementation of PCC in RCF are discussed in the article.

The prevalence of glaucoma in a 70-year-old Swedish population in the city area of Gothenburg

PURPOSE

To determine the prevalence of and risk factors for open-angle glaucoma in a population of 70-year-olds in Gothenburg, Sweden and to compare the visual function between the glaucoma population and the non-glaucoma population.

METHODS

Of the entire cohort (n = 1203), 1182 participants responded a questionnaire on self-reported glaucoma and were tested for blood pressure (BP) and diabetes. In all, 560 participants underwent ophthalmic examination including best-corrected visual acuity (BCVA), intraocular pressure (IOP), central corneal thickness (CCT), contrast sensitivity (CS), perimetry and photos of the retina and lens.

RESULTS

Glaucoma prevalence was 4.8% (95% confidence interval, 3.0%-6.6%), of which 56% was previously undiagnosed. The proportion of participants with diastolic BP >90 mmHg was higher in the non-glaucomatous group (8.3%) than the glaucoma group (0%), p < 0.001. A family history of glaucoma was present in a larger proportion of the glaucoma group (39%) than of the non-glaucomatous group (1.1%), p = 0.001. Mean IOP in individuals without glaucoma was 16 mmHg, versus 21 mmHg in participants with glaucoma detected at the examination. IOP was ≤21 mmHg in 67% among participants with previously unknown glaucoma. BCVA was lower in eyes with previously unknown glaucoma than in eyes without glaucoma (p = 0.017) but BCVA in the best eye did not differ. CCT and CS were similar in all cases.

CONCLUSIONS

The prevalence of glaucoma was comparable to that reported previously. A family history of glaucoma and higher IOP were risk factors associated with glaucoma. BCVA in the best eye did not differ significantly between subjects with and without glaucoma.

Vision-related quality of life among 70-year-olds diagnosed with glaucoma

PURPOSE

To evaluate the effect of glaucoma on vision-related quality of life (VRQoL), lifestyle, physical factors and socioeconomic status in a 70-year-old population in Gothenburg, Sweden.

METHODS

Responses to questionnaires (N = 1182) between groups with and without self-reported glaucoma were analysed. Questionnaires included National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25), Short-Form Health Survey (SF-36), physical activity, socioeconomics, alcohol and tobacco consumption. Balance test and body mass index were also included. About half of the participants were randomized to ophthalmic examination (N = 560), variables were analysed separately according to known and confirmed glaucoma, ocular hypertension and/or cases of previously unknown glaucoma.

RESULTS

Both conventional and Rasch analysis of the NEI VFQ-25 showed that VRQoL was lower for individuals self-reporting glaucoma (p = 0.003/p = 0.024). Regarding general QoL, the participants did not differ apart from people self-reporting glaucoma reported worse general health (p = 0.01). Using logistic regression with lower VRQoL as the dependent variable glaucoma was not a significant predictor of poor VRQoL, odds ratio (OR) 1.83 (95% confidence interval (CI) 0.76-4.39, p = 0.18). Low household income was associated with lower VRQoL (OR 1.63, 95% CI 1.14-2.33, p = 0.01). Socioeconomics, physical activity and lifestyle factors were comparable between the groups (N = 915). Among participants who underwent ophthalmic examination no significant differences were found between glaucoma cases and non-glaucoma cases in relation to VRQoL (N = 560).

CONCLUSIONS

Patients with self-reported glaucoma assessed a lower VRQoL but not lower general quality of life. Poorer household income was associated with worse VRQoL. General health was reported low in the glaucoma population but lifestyle or physical factors did not diverge.

Recovering from physical trauma in late life, a struggle to recapture autonomy: A grounded theory study

AIM

The study aimed to explore the experiences of care and recovery among older patients treated for physical trauma.

DESIGN

A qualitative study with a constructivist grounded theory design.

METHODS

Fifteen in-depth interviews with older adults recovering from physical trauma were conducted and analysed between 2019 and 2023, in accordance with grounded theory methodology.

RESULTS

The findings show that for older patients who suffered physical trauma, the core category was the strive to recapture autonomy. This was achieved by means of Adaptation, Reflection and Interactions, which constitute the three main categories. Recovery involves facing and navigating various new life challenges, such as increased dependency on others, managing difficult symptoms and adapting in various ways to everyday life. The recovery process was influenced by fear, hope and the attitude towards new challenges.

CONCLUSION

Older adults being cared for after a traumatic event have a difficult path to recovery ahead of them. Dealing with increased unwanted dependency on others was a main concern for the participants. Undertreated symptoms can lead to undesired isolation, delayed recovery and further increase unwanted dependency. On the other hand, hope, which was defined as having a positive approach to life and longing for the future, was a strong accelerating factor in the recovery process.

IMPACT

As a result of this study, we have established that older patients experience the initial period after trauma as difficult and that support in the initial phase can be helpful when returning home. As healthcare services are under increasing pressure because of an ageing population, this study contributes by addressing an understudied population and clarifying their concerns.

REPORTING METHOD

Reporting adheres to the COREQ (COnsolidated criteria for REporting Qualitative research) Checklist.

The effect of alcohol consumption on all-cause mortality in 70-year-olds in the context of other lifestyle risk factors: results from the Gothenburg H70 birth cohort study

BACKGROUND

In this study, we examined the effect of alcohol, as well as the combined effect of seven lifestyle factors, on all-cause mortality in older adults (baseline age 70 years).

METHODS

Data was derived from the population-based Gothenburg H70 Birth Cohort study, including 1124 participants from the 2014-16 examination. Risk consumption was defined as  > 98 g alcohol per week, and hazardous drinking was based on the Alcohol Use Disorders Identification Test-Consumption questionnaire (AUDIT-C). Cox regression models were used to examine the individual effect of alcohol consumption, as well as the combined effect of seven lifestyle risk factors (high alcohol consumption, lifetime smoking, unhealthy Body Mass Index, insufficient physical activity, sedentary behavior, insufficient/prolonged sleep, unhealthy dietary pattern) on all-cause mortality.

RESULTS

During a mean follow-up of 7.7 years, 81 (7.2%) participants died. Neither risk consumption nor hazardous drinking were associated with elevated mortality, but hazardous drinking was associated with an increased risk of mortality in those with insufficient physical activity. Those with at least five lifestyle risk factors had an increased all-cause mortality compared to those fulfilling criteria for a maximum of one lifestyle risk factor. High alcohol consumption showed a relatively minor impact on this risk, while physical activity and unhealthy dietary pattern had an independent effect on mortality.

CONCLUSIONS

In this particular sample, there was no independent effect of alcohol on the risk of 8-year all-cause mortality. However, an interaction effect of physical activity was observed. It may be that high alcohol consumption per se is less important for mortality among older adults. However, a combination of several unhealthy lifestyle behaviors was linked to a substantial increase in the risk of mortality in Swedish older adults. Also, it has to be emphasized that high alcohol consumption may have other adverse health effects apart from mortality among older adults.

Attrition in the Gothenburg H70 birth cohort studies, an 18-year follow-up of the 1930 cohort

Background

Longitudinal studies are essential to understand the ageing process, and risk factors and consequences for disorders, but attrition may cause selection bias and impact generalizability. We describe the 1930 cohort of the Gothenburg H70 Birth Cohort Studies, followed from age 70 to 88, and compare baseline characteristics for those who continue participation with those who die, refuse, and drop out for any reason during follow-up.

Methods

A population-based sample born 1930 was examined with comprehensive assessments at age 70 (N = 524). The sample was followed up and extended to increase sample size at age 75 (N = 767). Subsequent follow-ups were conducted at ages 79, 85, and 88. Logistic regression was used to analyze baseline characteristics in relation to participation status at follow-up.

Results

Refusal to participate in subsequent examinations was related to lower educational level, higher blood pressure, and lower scores on cognitive tests. Both attrition due to death and total attrition were associated with male sex, lower educational level, smoking, ADL dependency, several diseases, poorer lung function, slower gait speed, lower scores on cognitive tests, depressive symptoms, and a larger number of medications. Attrition due to death was also associated with not having a partner.

Conclusions

It is important to consider different types of attrition when interpreting results from longitudinal studies, as representativeness and results may be differently affected by different types of attrition. Besides reducing barriers to participation, methods such as imputation and weighted analyses can be used to handle selection bias.

Time trends in depression prevalence among Swedish 85-year-olds: repeated cross-sectional population-based studies in 1986, 2008, and 2015

BACKGROUND

Octogenarians of today are better educated, and physically and cognitively healthier, than earlier born cohorts. Less is known about time trends in mental health in this age group. We aimed to study time trends in the prevalence of depression and psychotropic drug use among Swedish 85-year-olds.

METHODS

We derived data from interviews with 85-year-olds in 1986-1987 (N = 348), 2008-2010 (N = 433) and 2015-17 (N = 321). Depression diagnoses were made according to the Diagnostic and Statistical Manual of Mental Disorders. Symptom burden was assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS). Information on psychotropic drug use, sociodemographic, and health-related factors were collected during the interviews.

RESULTS

The prevalence of major depression was lower in 2015-2017 (4.7%, p < 0.001) and 2008-2010 (6.9%, p = 0.010) compared to 1986-1987 (12.4%). The prevalence of minor depression was lower in 2015-2017 (8.1%) compared to 2008-2010 (16.2%, p = 0.001) and 1986-1987 (17.8%, p < 0.001). Mean MADRS score decreased from 8.0 in 1986-1987 to 6.5 in 2008-2010, and 5.1 in 2015-2017 (p < 0.001). The reduced prevalence of depression was not explained by changes in sociodemographic and health-related risk factors for depression. While psychoactive drug use was observed in a third of the participants in each cohort, drug type changed over time (increased use of antidepressants and decreased use of anxiolytics and antipsychotics).

CONCLUSIONS

The prevalence of depression in octogenarians has declined during the past decades. The decline was not explained by changes in known risk factors for depression. The present study cannot answer whether changed prescription patterns of psychoactive drugs have contributed to the decline.

Alcohol use and drinking patterns in Swedish 85 year olds born three decades apart - findings from the Gothenburg H70 study

BACKGROUND

Little is known about alcohol consumption among the oldest old.

OBJECTIVE

To compare alcohol use and drinking patterns among 85 year olds born three decades apart.

DESIGN

Cross-sectional.

SETTING

The Gothenburg H70 Birth Cohort Studies.

SUBJECTS

About 1,160 85 year olds born in 1901-02, 1923-24, and 1930.

METHODS

Self-reported questions about alcohol included how often study participants drank beer, wine, and spirits and how many centilitres in total/week. Risk consumption was defined as ≥100 g alcohol/week. Descriptive statistics and logistic regression were used to explore cohort characteristics, differences in proportions, factors associated with risk consumption and 3-year mortality.

RESULTS

The proportion of at-risk drinkers increased from 4.3 to 14.9% (9.6-24.7% in men and 2.1-9.0% in women). The proportion of abstainers decreased from 27.7 to 12.9%, with the largest decrease observed among women (29.3-14.1%). Controlling for sex, education and marital status, 85 year olds in the later-born cohorts were more likely to be risk consumers than those in the earlier-born cohort [odds ratio (OR) 3.1, 95% confidence nterval (CI) 1.8-5.6]. The only factor associated with an increased likelihood was male sex (OR 3.7, 95% CI 1.0-12.7 and OR 3.2, 95% CI 2.0-5.1). There were no associations between risk consumption of alcohol and 3-year mortality in any of the cohorts.

CONCLUSION

Alcohol consumption and the number of risk consumers among 85 year olds have increased considerably. This could have large public health consequences since older adults are more sensitive to alcohol's adverse health effects. Our findings show the importance of detecting risk drinkers also in the oldest old.

Decreasing incidence and prevalence of dementia among octogenarians. A population-based study on three cohorts born 30 years apart

BACKGROUND

Recent studies suggest a decline in the age-specific incidence and prevalence of dementia. However, results are mixed regarding trends among octogenarians. We investigated time trends in the prevalence and incidence of dementia in three population-based cohorts of 85-90-year-olds. We also examined if there were different time trends for men and women.

METHODS

We examined population-based birth cohorts within the Gothenburg H70 Birth Cohort Studies born 1901-02, 1923-24, and 1930, at ages 85 (N=1481) and 88 (N=840) years. The first two cohorts were also examined at age 90 (N=450). The incidence was examined in 1109 individuals free from dementia at baseline using information from the examination at age 88 or register data. All three cohorts were examined with identical methods.

RESULTS

The prevalence of dementia decreased from 29.8% in 1986-87 to 21.5% in 2008-10 and 24.5% in 2015-16 among 85-year-olds, and from 41.9% in 1989-90 to 28.0% in 2011-12 to 21.7% in 2018-19 among 88-year-olds, and from 46.5% in 1991-92 to 37.2% in 2013-14 among 90-year-olds. The decline was most accentuated among women. The incidence of dementia per 1,000 risk-years from age 85 to 89 declined from 48.8 among those born 1901-02 to 37.9 in those born 1923-24 to 22.5 among those born 1930.

CONCLUSIONS

The prevalence and incidence of dementia decreased substantially over three decades among octogenarians. This might slow down the projected increase in cases of dementia expected by the increasing number of octogenarians during the following decades.

The Association Between the Clinical Frailty Scale and Adverse Health Outcomes in Older Adults in Acute Clinical Settings - A Systematic Review of the Literature

Background

Frail older adults experience higher rates of adverse health outcomes. Therefore, assessing pre-hospital frailty early in the course of care is essential to identify the most vulnerable patients and determine their risk of deterioration. The Clinical Frailty Scale (CFS) is a frailty assessment tool that evaluates pre-hospital mobility, energy, physical activity, and function to generate a score that ranges from very fit to terminally ill.

Purpose

To synthesize the evidence of the association between the CFS degree and all-cause mortality, all-cause readmission, length of hospital stay, adverse discharge destination, and functional decline in patients >65 years in acute clinical settings.

Design

Systematic review with narrative synthesis.

Methods

Electronic databases (PubMed, EMBASE, CINAHL, Scopus) were searched for prospective or retrospective studies reporting a relationship between pre-hospital frailty according to the CFS and the outcomes of interest from database inception to April 2020.

Results

Our search yielded 756 articles, of which 29 studies were included in this review (15 were at moderate risk and 14 at low risk of bias). The included studies represented 26 cohorts from 25 countries (N = 44166) published between 2011 and 2020. All included studies showed that pre-hospital frailty according to the CFS is an independent predictor of all adverse health outcomes included in the review.

Conclusion

A primary purpose of the CFS is to grade clinically increased risk (i.e. risk stratification). Our results report the accumulated knowledge on the risk-predictive performance of the CFS and highlight the importance of routinely including frailty assessments, such as the CFS, to estimate biological age, improve risk assessments, and assist clinical decision-making in older adults in acute care. Further research into the potential of the CFS and whether implementing the CFS in routine practice will improve care and patients' quality of life is warranted.

Representativeness in population-based studies of older adults: five waves of cross-sectional examinations in the Gothenburg H70 Birth Cohort Study

OBJECTIVES

To describe representativeness in the Gothenburg H70 1930 Birth Cohort Study.

DESIGN

Repeated cross-sectional examinations of a population-based study.

SETTING

Gothenburg, Sweden.

PARTICIPANTS

All residents of Gothenburg, Sweden, born on specific birth dates in 1930 were invited to a comprehensive health examination at ages 70, 75, 79, 85 and 88. The number of participants at each examination was 524 at age 70, 767 at age 75, 580 at age 79, 416 at age 85, and 258 at age 88.

PRIMARY OUTCOME MEASURES

We compared register data on sociodemographic characteristics and hospital discharge diagnoses between participants and (1) refusals, (2) all same-aged individuals in Gothenburg and (3) all same-aged individuals in Sweden. We also compared mortality rates between participants and refusals.

RESULTS

Refusal rate increased with age. At two or more examination waves, participants compared with refusals had higher educational level, more often had osteoarthritis, had lower mortality rates, had lower prevalence of neuropsychiatric, alcohol-related and cardiovascular disorders, and were more often married. At two examination waves, participants compared with same-aged individuals in Gothenburg had higher education and were more often born in Sweden. At two examination waves or more, participants compared with same-aged individuals in Sweden had higher education, had higher average income, less often had ischaemic heart disease, were less often born in Sweden and were more often divorced.

CONCLUSIONS

Participants were more similar to the target population in Gothenburg than to refusals and same-aged individuals in Sweden. Our study shows the importance of having different comparison groups when assessing representativeness of population studies, which is important in evaluating generalisability of results. The study also contributes unique and up-to-date knowledge about participation bias in these high age groups.

Pseudophakia and Lens Opacities in 70-Year-Olds in Gothenburg, Sweden; Gender Differences, Impact on Self-Reported Visual Function and Validation of Self-Reported Cataract and Pseudophakia

Purpose

The study aimed at determining the prevalence and sex differences in cataract, pseudophakia, lens opacities and self-reported cataract in 70-year-old people in Gothenburg, Sweden. The purpose was also to identify correlations between lens opacities, visual acuity and subjective visual function, and to validate self-reported cataract and cataract surgery.

Patients and Methods

Population-based cross-sectional study where participants (n=1182) answered questions about self-reported diagnosis of cataract and cataract surgery. A total of 1139 subjects completed the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25), 560 subjects underwent ophthalmic examination including visual acuity and lens photography. t-test, Pearson chi-square and Mann-Whitney U-test were used for obtaining p-values. ANOVA (analysis of variances, Kruskal-Wallis, one-way) was used to compare VFQ-25 between 3 groups; no cataract, cataract and pseudophakia. To clarify the differences between specific pairs of groups post-hoc test (Bonferroni) was used after ANOVA.

Results

Self-reported cataract was more common in women than in men (27.2% vs 19.1%, p=0.001, chi-square). Cataract surgery was reported by 16.3% of women and 12.6% of men (p=0.072). Upon eye examination, the prevalence of pseudophakia was 16.9% in women compared to 10.2% in men (p=0.020). The prevalence of cataract, including pseudophakia, was 31.9% in women versus 23.8% in men (p=0.033). Significant correlations (Spearman's rho) were found between lens opacities and visual acuity. Self-reported cataract surgery showed a very high specificity and high sensitivity. The composite score from NEI VFQ-25 was lower in people with pseudophakia than in people with/without cataract (p=0.012, Kruskal-Wallis).

Conclusion

The prevalence of cataract including pseudophakia in 70-year-olds in Gothenburg is higher compared to previous studies in similar geographical areas. Also, it is more common in women than in men. The lack of significant sex differences in lens opacities may be due to cataract surgery at an earlier stage. Validation showed very good agreement between pseudophakia and self-reported cataract surgery.

Activities of daily living (ADL) and instrumental activities of daily living (IADL) disability in Swedish 85-year-olds born three decades apart-findings from the H70 study

OBJECTIVE

Older adults make up the fastest growing segment of the population, and disability rates increase with age. There is much debate whether later born cohorts of 85-year-olds will face the same disability rates as earlier born cohorts. This study aimed to examine ADL and IADL disability in three birth cohorts of Swedish 85-year-olds born three decades apart, examined in 1986-87, 2008-10 and 2015-16, as well as potential factors associated with ADL and IADL disability in these birth-cohorts.

METHODS

Systematically selected population-based birth cohorts of 85-year-olds (n = 1,551) from the Gothenburg H70 Birth Cohort studies, Sweden, born in 1901-02 (n = 494), 1923-24 (n = 571) and 1930 (n = 486) and examined with identical methods. Disability was defined as a need for assistance in any ADL/IADL activities.

RESULTS

ADL/IADL disability decreased between cohorts in both men and women (from 76.7% in 1986-87, to 58.4% in 2008-10, and 48.4% in 2015-16, P-value trend <.001). Factors associated with ADL/IADL disability varied between cohorts, although dementia and depression increased the odds of disability in all three birth cohorts.

CONCLUSION

Later born cohorts of 85-year-olds face less ADL/IADL disability compared to earlier born cohorts. As disability poses a significant financial burden on healthcare services, our findings might contribute to a more positive view on global ageing and the demographic challenges ahead. However, it might also be that in later born cohorts, ADL/IADL disability affects people at later ages, but due to increased longevity, the total number of years in late-life with a functional disability will remain the same.

Comparison of the 2010 and 2019 diagnostic criteria for sarcopenia by the European Working Group on Sarcopenia in Older People (EWGSOP) in two cohorts of Swedish older adults

Background

The operational definition of sarcopenia has been updated (EWGSOP2) and apply different cut-off points compared to previous criteria (EWGSOP1). Therefore, we aim to compare the sarcopenia prevalence and the association with mortality and dependence in activities of daily living using the 2010 (EWGSOP1 and 2019 (EWGSOP2 operational definition, applying cut-offs at two levels using T-scores.

Methods

Two birth cohorts, 70 and 85-years-old (n = 884 and n = 157, respectively), were assessed cross-sectionally (57% women). Low grip strength, low muscle mass and slow gait speed were defined below − 2.0 and − 2.5 SD from a young reference population (T-score). Muscle mass was defined as appendicular lean soft tissue index by DXA. The EWGSOP1 and EWGSOP2 were applied and compared with McNemar tests and Cohen’s kappa. All-cause mortality was analyzed with the Cox-proportional hazard model.

Results

Sarcopenia prevalence was 1.4–7.8% in 70-year-olds and 42–62% in 85 years-old’s, depending on diagnostic criteria. Overall, the prevalence of sarcopenia was 0.9–1.0 percentage points lower using the EWGSOP2 compared to EWGSOP1 when applying uniform T-score cut-offs (P <  0.005). The prevalence was doubled (15.0 vs. 7.5%) using the − 2.0 vs. -2.5 T-scores with EWGSOP2 in the whole sample. The increase in prevalence when changing the cut-offs was 5.7% (P <  0.001) in the 70-year-olds and 17.8% (P <  0.001) in the 85-year-olds (EWGSP2). Sarcopenia with cut-offs at − 2.5 T-score was associated with increased mortality (hazard ratio 2.4–2.8, P <  0.05) but not at T-score − 2.0.

Conclusions

The prevalence of sarcopenia was higher in 85-year-olds compared to 70-year-olds. Overall, the differences between the EWGSOP1 and EWGSOP2 classifications are small. Meaningful differences between EWGSOP1 and 2 in the 85-year-olds could not be ruled out. Prevalence was more dependent on cut-offs than on the operational definition.

Dizziness and health-related quality of life among older adults in an urban population: a cross-sectional study

Background

Dizziness is a common complaint among older adults and may affect quality of life in a negative way. The aim of this study was to assess health-related quality of life (HRQL), sense of coherence (SOC), self-rated health (SRH) and comorbidity in relation to dizziness, among older persons from an urban population.

Methods

The study is part of the Gothenburg H70 Birth Cohort Studies (H70). A cross-sectional population-based sample including 662 79-years-olds (404 women, 258 men, 62% response rate) were surveyed with questions regarding dizziness, imbalance, comorbidities and general health. HRQL was assessed using the 36-item Short Form-36 Health Survey (SF-36) and SOC with the 13-items questionnaire Sense of Coherence (SOC-13).

Results

Half of the participants reported problems with dizziness (54%). Dizziness was negatively associated with HRQL, including after adjusting for comorbidities, especially in the physical domains of SF-36. Having dizziness was also associated with poorer SRH, tiredness and comorbidity among both men and women. SOC (mean total score), however, did not differ between dizzy and non-dizzy participants.

Conclusions

Dizziness was negatively associated with HRQL, also after adjusting for comorbidities. Identification and treatment of dizziness, when possible, are important because reduction of dizziness symptoms may potentially help to enhance overall well-being in this age group.

Dementia remains the major predictor of death among octogenarians. A study of two population cohorts of 85-year-olds examined 22 years apart

Dementia is the major predictor of death in old age. The aim of this paper was to determine whether 8-year mortality among 85-year olds with and without dementia, and if the contribution of dementia to mortality relative to other common diseases has changed. We used two population-based cohorts of 85-year-olds (N = 1065), born in 1901–02 and 1923–24, which were examined with identical methods in 1986–87 and 2008–2010 and followed for 8-year mortality according to data from the Swedish Tax Agency. Dementia was diagnosed according to DSM-III-R. Other diseases were diagnosed based on self-reports, close informant interviews, somatic examinations, and the Swedish National In-patient Register. Compared to cohort 1901–02, cohort 1923–24 had a lower 8-year mortality both among those with (HR 0.7; 95% CI 0.5–0.99) and without dementia (HR 0.7; 95% CI 0.5–0.9). Dementia was associated with increased mortality in both cohorts (cohort 1901–02, HR 2.6; 95% CI 2.0–3.2, cohort 1923–24, HR 2.8; 95% CI 2.3–3.5), and remained the major predictor of death, with a population attributable risk of 31.7% in 1986–87 and 27.7% in 2008–10. Dementia remained the most important predictor of death in both cohorts. The relative risk for mortality with dementia did not change between cohorts, despite a decreased mortality rate in the population.

Self-perceived functional ability and performance-based testing of physical function in older women with or without long-term back pain - results of the H70 study

Background

The proportion of older adults is increasing rapidly, and the majority are female. In 2050, the number of persons aged 60 years and over is estimated to reach 2.1 billion worldwide, constituting one-third of the total population of Europe. Long-term back pain is a disabling and common condition, primarily affecting older women. Although standardized functional evaluations are essential in the screening of older adults, self-rated activities of daily living capture a different aspect of the person’s ability in the context of his or her environment and social support system. This study aimed to describe how older women with or without long-term back pain self-rate their activities of daily living (ADL) and instrumental activities of daily living (IADL) in relation to their performance-based testing of physical function, including walking test, leg muscle strength, balance, and endurance.

Method

This study is part of the Gothenburg H70 Birth Cohort Studies in Sweden (H70 studies) and uses data from the 1944 birth cohort examined in 2015–16 at age 70. In the present study, only female participants were included in the analysis, and all cases of dementia (n = 17) and cases of acute and sub-acute back pain excluded (n = 181), leaving an effective sample of 446 female participants.

Results

Women with long-term back pain self-perceived their ADL and IADL as being as good as those without back pain, although they performed poorer in all performance-based tests and perceived themselves as less physically fit.

Conclusion

The discrepancy between self-perceived functional ability (ADL/IADL) and performance-based testing of functioning based on clinical tests calls for further investigation to incentivize person-centered care in older women with long-term back pain in municipal or emergency health-care settings.

Benign paroxysmal positional vertigo, dizziness, and health-related quality of life among older adults in a population-based setting

Purpose

Dizziness may affect quality of life in a negative way and contribute to falls. The aim of this study was to investigate and compare 75 years old with dizziness caused by benign paroxysmal positional vertigo (BPPV) to those with general dizziness/impaired balance (non-BPPV related) and to those reporting no dizziness, regarding health-related quality of life (HRQL), falls, tiredness, and walking speed in a population-based setting.

Method

A cross-sectional population-based sample, including 671 75 years old (398 women, 273 men), was investigated for BPPV, dizziness symptoms, falls, and walking speed. HRQL was assessed using the 36-item Short Form-36 Health Survey (SF-36).

Result

A total of 67 persons (10%) had symptoms of BPPV with 11 (1.6%) having nystagmus when tested for BPPV. Having BPPV as well as general dizziness/impaired balance was associated with reduced HRQL, more tiredness, enhanced number of falls, and lower walking speed. Furthermore, the risk of having BPPV increased fourfold if symptoms of dizziness when turning in bed was reported.

Conclusion

Having problems with dizziness is common among senior citizens where BPPV can be an unrecognized cause of dizziness that may impact HRQL and overall well-being. As BPPV is common among older adults, and is potentially curable through reposition maneuvers, it is important to liberally test for, and treat the condition. Information about dizziness when turning in bed can help to pinpoint persons with enhanced risk for BPPV also on a population-based level.

Vision-related quality of life and visual function in a 70-year-old Swedish population

PURPOSE

To investigate vision-related quality of life (VRQoL), visual function and predictors of poor vision in a population of 70-year-olds.

METHODS

Self-reported ocular morbidity and responses to the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) in a cross-sectional population study (N = 1203) in Gothenburg, Sweden, were compared with results from ophthalmic examination (N = 560).

RESULTS

The most common self-reported ophthalmic morbidities were cataract (23.4%), age-related macular degeneration (AMD; 4.7%), glaucoma (4.3%) and diabetic retinopathy (1.4%). Cataract was more prevalent in women (p = 0.001). The composite score from NEI VFQ-25 for the entire cohort was 91.4 (standard deviation: 27.5). When comparing composite score for different eye diseases, persons with cataract or AMD exhibited lower scores (p = 0.029 and 0.018, respectively). Best-corrected visual acuity (BCVA) was normal (≥0.5 decimal) in 98.9%; two individuals had low vision (<0.3). Men exhibited better BCVA (median: -0.08 logMAR) than women (-0.06; p = 0.005). Visual field defects were observed in 16.3% and uncorrected refractive errors in 61.5%. Poor vision was reported by 7.4% of participants with presenting visual acuity (PVA) ≥0.5 (decimal), while 66.7% with PVA <0.5 reported good vision. Of 27 individuals with PVA <0.5, 55.6% obtained a BCVA of ≥1.0 with the right correction. Low contrast sensitivity was a significant predictor of experiencing poor vision (p = 0.008), while PVA and visual field defects were not.

CONCLUSIONS

Low contrast sensitivity is a predictor of experiencing poor vision. There is a discrepancy between subjective/objective visual function and a high prevalence of uncorrected refractive errors. Women have more cataract, and men demonstrate slightly better visual acuity.

Internet use and self-rated health among Swedish 70-year-olds: a cross-sectional study

Background

The Internet is increasingly becoming an infrastructure for a number of services, both commercial, public (including health related) and personal. Using the internet have the potential to promote social interaction and social connectedness by upholding social networks and social contacts. However, Internet use is lower in older adults compared to other age groups. This digital divide is considered a risk to the health of older adults since it limits their participation in society, access and use of relevant health related information and services. This study focuses on whether there is an association between Internet use and self-rated health.

Method

A cross-sectional population-based sample of 70-year-olds from The Gothenburg H70 Birth Cohort Study (n = 1136) was examined in 2014–16. All data was collected using structured interviews and questionnaires. Differences in proportions were tested with chi-square test and ordinary least square regression analysis was used to estimate the relationship between Internet use and self-rated health controlling for health factors, hearing and visual impairment, and social contacts.

Results

There is a relationship between more frequent Internet use and good self-rated health (unstandardized β 0.101 p < 0.001), and the effect remained after adjusting for all covariates (unstandardized β 0.082 p < 0.001). Our results also show that, in comparison to health factors, Internet use is of minor importance to the SRH of older adults, since adding these improved the explanatory power of the model by approximately 400% (from 0.04 to 0.18).

Conclusion

Although the direction of the relationship between more frequent interne use and better self-rated health is undetermined in the present study, it can be suggested that using the Internet informs and educates older adults, strengthening their position as active and engaged participants of society. It can also be suggested that those using the Internet report less loneliness and a possibility to establish new computer-mediated relationships within online communities. Further research needs to examine what aspects of Internet use, and in what contexts such positive perceptions arise.

Was it worth it? Older adults' experiences of participating in a population-based cohort study - a focus group study

BACKGROUND

At present, we know relatively little about priorities and problems with topics that older adults experience when completing different examinations in longitudinal population-based studies. To examine these topics, research must be adapted to investigate the meanings, motivations, and interpretations of the individual participants themselves. Therefore, the present study aimed to explore older adults' motives, understandings and experiences regarding participating in the Gothenburg H70 Birth Cohort Studies (the H-70 study).

METHODS

Focus group discussions were used. A total of thirty-eight persons, 19 women and 19 men participated in nine focus groups. A strategic sampling technique was used to ensure that the focus group participants represented the larger population.

RESULTS

The results supported the overall theme: "It was well worth the effort," which summarized how the participants felt about the population health study. The following specific themes were also identified: an intense event, for the benefit of oneself and others, confidence in health research and the researcher, key decisions about test outcomes and the survey raising questions and providing few answers.

CONCLUSIONS

Knowledge of priorities and problems with topics experienced by older adults completing different examinations when participating in longitudinal population-based studies is crucial for research to improve the health and wellbeing of older people. To date, older people's involvement in population-based cohort studies has largely been as research subjects. This study is a first step toward the participants taking a more active part by allowing them to share their experiences which can be used to improve the research procedures. This requires the participation of older adults in collaboration with the researchers, to ensure the quality of longitudinal studies of older adults. Therefore, our intention when it comes to future research will be to involve older adults-the target group-in the research procedure.

Agreement between self-reports, proxy-reports and the National Patient Register regarding diagnoses of cardiovascular disorders and diabetes mellitus in a population-based sample of 80-year-olds

Background

cognitive impairment is common among older adults, necessitating the use of collateral sources in epidemiological studies involving this age group. The objective of this study was to evaluate agreement between self- and proxy-reports of cardiovascular disorders and diabetes mellitus in a population-based sample of 80-year-olds. Further, both self- and proxy-reports were compared with hospital register data.

Methods

data were obtained from the Gothenburg H70 Birth Cohort Studies in Sweden. The study had a cross-sectional design and information was collected through semi-structured interviews in 2009–2012 from participants born in 1930 (N = 419) and their proxy informants. The National Patient Register provided diagnoses registered during hospital stays. Agreement was measured with Kappa values (K).

Results

agreement between self- and proxy-reports was substantial for diabetes mellitus (K = 0.79), atrial fibrillation (K = 0.61), myocardial infarction (K = 0.75), angina pectoris (K = 0.73) and hypertension (K = 0.62), and fair for intermittent claudication (K = 0.38) and heart failure (K = 0.40). Compared to the National Patient Register, a large proportion of those with a hospital discharge diagnosis were also self- and proxy-reported.

Conclusions

proxy informants can be an important source of information, at least for well-defined conditions such as myocardial infarction, angina pectoris and diabetes mellitus.
