Malnutrition and cognitive impairment among people 60 years of age and above living in regular housing and in special housing in Sweden: A population-based cohort study

BACKGROUND Malnutrition is a common problem among older people and associated with reduced functional and cognitive ability. Furthermore, malnutrition among people living in special housing, i.e. in nursing homes or sheltered accommodation, appears to be more common than among those living in regular housing, i.e. in their own homes. However, it is still unclear if the relationship between malnutrition and impaired cognitive ability is connected to living arrangement, i.e. if the relationship is stronger among those who live alone compared to those who cohabit in regular housing. OBJECTIVES The purpose with the present study was to describe the relationship between nutritional status and cognitive ability among people 60 years of age and above in Sweden, with a focus on housing and living arrangement. DESIGN Population-based cohort study. SETTING AND PARTICIPANTS The study focused on people living in regular or in special housing and comprised 1,402 randomly selected individuals (60-96 years of age) who lived in one municipality in south-eastern Sweden and participated in SNAC-B (the Swedish study on Aging and Care - Blekinge), 2001-2003. METHODS Data regarding demography, nutrition and functional and cognitive ability were collected through questionnaires, medical examinations and structured interviews. RESULTS The relationship was the strongest between cognitive ability and nutritional status among those living in special housing. Regardless of housing and living arrangement, older people with a moderate or severe cognitive impairment risked (OR 2.59-16.00) being malnourished, irrespective of functional ability. CONCLUSION This study highlights that those with a moderate and severe cognitive impairment suffer a risk of developing malnutrition, irrespective of living and housing arrangement. The findings suggest that nurses in the social service and health care system need to consider changes in weight and nutritional intake as well as the individual needs of older people with cognitive impairment to avoid malnutrition.

Mobility, functional ability and health-related quality of life among people of 60 years or older.

Background and aims: Knowledge about Health-Related Quality of Life (HRQoL) in advanced age is sparse. This study investigated to what extent mobility factors explained older people’s HRQoL when age, gender and functional ability (ADL) were controlled for. Methods: Subjects were 1128 people aged 60–96 participating in a Swedish longitudinal multi-center cohort study. Besides descriptive and correlation statistics, a three-tier multiple logistic regression analysis was performed, which included the ADL scale, mobility tests and items, with physical and mental HRQoL as outcome variables. Results: In the models containing the control variables, functional ability was found to be associated with both physical and mental HRQoL. In the models including both functional ability and mobility factors, the importance of functional ability remained for mental but not for physical HRQoL. The mobility factors were found to have a stronger negative influence on HRQoL, i.e., physical and mental, than functional ability in itself. Conclusions: For optimal identification of various types of disabilities and their impact on older people’s HRQoL, the ADL scale should be used together with more targetspecific tests of disabilities. However, in certain situations, it appears that one mobility factor alone — the ability to walk — has the capacity to pick up changes in both physical and mental HRQoL. Thus, it is important that healthcare professionals should focus activities toward maintaining older people’s mobility as a means of enhancing their HRQoL.

Determinants of feeling hindered by health problems in daily living at 60 years and above

Although the ability to perform activities of daily living (ADL) is frequently used to identify the impact on daily living caused by health problems such as diseases, impaired eyesight or hearing, it is still not well known what makes people feel hindered in daily living with more or less inability to perform ADL. The aim of this study was to investigate feeling hindered by health problems in daily living among people (n = 958, 60-96 years) in relation to ADL capacity, health problems as well as social and financial resources, sense of coherence and life satisfaction. The data are taken from a baseline survey in one of the four included centres (Blekinge) of the longitudinal multicentre cohort study, The Swedish National Study on Aging and Care. The result showed that people felt hindered by their health problems despite no impairment in ADL capacity. Feeling greatly hindered by health problems was associated with factors linked to mobility but also to fatigue, no help when needed, and avoiding being outdoors due to fear of falling. Factors associated with feeling greatly hindered differed depending on whether people were impaired in ADL capacity or not. In people with excellent ADL capacity feeling hindered was associated with picking up things from the floor and rising from a chair and fatigue, whereas avoiding being outdoors, no help when needed and rising from a chair were found to be associated with feeling hindered by health problems among people with impaired ADL capacity. Combining peoples ADL capacity with questions about feeling hindered may provide knowledge of determinant factors of feeling hindered in relation to ADL capacity, impaired or not, to identify people in need of rehabilitation or other interventions.

Nursing students' understanding of critical thinking and appraisal and academic writing: A descriptive, qualitative study

In Sweden, regulations from the National Agency for Higher Education advocate an education that equips students with independence as well as critical, problem-based thinking, i.e. academic literacy skills. However, some research findings indicate that students may leave higher education without mastering these skills effectively. As part of quality-assuring a nursing programme at a university college in south-east Sweden we explored the nursing students view of crucial academic literacy skills, such as critical thinking and appraisal and academic writing, by conducting a descriptive, qualitative study. Informants were recruited through an advertisement posted on the universitys e-learning tool. Eight focused interviews were conducted during autumn 2010. The transcribed interviews were analysed - inspired by content analysis - and two categories became apparent: constantly questioning and formality before substance. The latter revealed a gap between the students perception of academic writing and that of the educators, thus implying that nursing students might not be equipped with the tools they need to develop within academia. We suggest that students could benefit in their academic endeavours from theoretical educational models that integrate several academic skills simultaneously and which could be incorporated into the development of syllabuses and curriculums.

Factors related to frequent usage of the primary healthcare services in old age: findings from The Swedish National Study on Aging and Care

People aged 60 or more are the most frequent users of healthcare services. In this age range, however, both frequent and infrequent users can be found. Frequent users have high rates of illnesses. Previous research has found that the frequency may be influenced also by psychological and social factors. The aim of this study was to investigate to what degree such factors add to the explanation of differences in number of visits to a physician. A cross-sectional study was conducted with a random sample consisting of 1017 individuals, aged 60 to 78 years, from the Blekinge part of the Swedish National Study on Aging and Care database. The data were collected during 2001 to 2003. Hierarchical logistic regression analyses were used with frequent (three visits or more during a year) and infrequent use as a dichotomous dependent variable. The final statistical analyses included 643 individuals (63% of the sample). Independent variables were sense of coherence (SOC), internal locus of control, education level and social anchorage. Control variables were age, gender, functional ability and comorbidity. The results showed that comorbidity was most strongly related to frequent use [adjusted odds ratio (OR) = 8.17, 95% confidence interval (CI) 5.54–12.04]. In addition, SOC and internal locus of control had small, but significant effects on the odds of being a frequent user (adjusted OR = 1.03, 95% CI 1.00–1.06 and adjusted OR = 1.14, 95% CI 1.02–1.27, respectively). The lower the SOC and the internal locus of control were, the higher were the odds of frequent use. Education level and social anchorage were unrelated to frequency of use. The results indicate that frequent healthcare services users are more ill than infrequent users. Psychological factors influence the use only marginally, and social factors as well as age and gender are not by themselves reason for frequent healthcare services use.

Malnutrition, functional ability and mortality among older people aged 60 years: a 7-year longitudinal study

Background/Objectives:This study aimed to assess the association between risk of malnutrition and 7-year mortality, controlling for functional ability, socio-demographics, lifestyle behavior and diseases, and investigate the interaction between risk of malnutrition and functional ability on the risk of mortality.Subjects/Methods:A longitudinal study on home-living and special-housing residents aged ⩾60 years was conducted. Of 2312 randomly invited participants, 1402 responded and 1203 provided information on both nutritional status and functional ability. The risk of malnutrition was estimated by the occurrence of at least one anthropometric measure (BMI, MAC and CC) below cut-off in addition to the presence of at least one subjective measure (decreased food intake, weight loss and eating difficulty).Results:At baseline, 8.6% of subjects were at risk of malnutrition and during the 7-year follow-up 34.6% subjects died. The risk of malnutrition was independently associated with 7-year mortality (hazard ratio (HR) 1.84, 95% confidence interval (CI) 1.28–2.65). Additional independent predictors were dementia (HR 2.76, 95% CI 1.85–4.10), activity of daily living (ADL) dependence (HR 2.08, 95% CI 1.62–2.67), heart disease (HR 1.44, 95% CI 1.16–1.78), diabetes (HR 1.41, 95% CI 1.03–1.93) and older age (HR 1.09, 95% CI 1.07–1.10). Moreover, the risk of malnutrition and ADL dependence in combination predicted the poorest survival rate (18.7%, P<0.001).Conclusions:The risk of malnutrition significantly increases the risk of mortality in older people. Moreover, risk of malnutrition and ADL dependence together explain a significantly poorer survival rate; however, the importance of this interaction decreased in the multivariable model and risk of malnutrition and ADL dependence independently explained a significant risk of mortality.

Sleep complaints and their association with comorbidity and health-related quality of life in an older population in Sweden

Objective: The relationship between sleep complaints, comorbidity and health-related quality of life (HRQoL) in advanced age has not been clearly established. The aim of this study is therefore to investigate the presence of sleep complaints and discuss their association with morbidity and the HRQoL among the people aged 60 years and above. Methods: Data regarding demography, sleep, comorbidity and HRQoL were collected through questionnaires and interviews among 1128 people in Sweden. The Johns Hopkins adjusted clinical groups (ACG®) Case-Mix System 6.0 and the Short-Form Health Survey-12 were used to assess morbidity and HRQoL, respectively. Results: There was a divergence in the number of sleep complaints between those with no morbidity and those who had a high degree of comorbidity. Most of the sleep complaints related to low HRQoL were found among those with a high degree of comorbidity. Conclusions: People with a high degree of comorbidity appear to be a group with a high risk of having both sleep complaints and a low HRQoL. Thus, this study suggests that even if sleep complaints appear to be difficult to identify and treat successfully, it is important to pay particular attention to those people who suffer from a high degree of comorbidity if their HRQoL is to be maintained.

Prevalence and predictors of healthcare utilization among older people (60+): Focusing on ADL dependency and risk of depression.

The aim of this study was to investigate healthcare utilization patterns over a six-year period among older people (60+), classified as dependent/independent in Activities of Daily Living (ADL) and/or at/not at risk of depression and to identify healthcare utilization predictors. A sample (n=1402) comprising ten age cohorts aged between 60 and 96 years was drawn from the Swedish National study on Aging and Care (SNAC). Baseline data were collected between 2001 and 2003. Number and length of hospital stays were collected for six years after baseline year. Group differences and mean changes over time were investigated. Healthcare utilization predictors were explored using multiple linear regression analysis. The results revealed that 21-24% had at least one hospital stay in the six years after baseline, 29-37% among ADL dependent subjects and 24-33% among those at risk of depression. There was a significant increase of hospital stays in all groups over time. ADL-dependent subjects and those at risk of depression had significant more hospital stays, except for those at/not at risk of depression in years 2, 4 and 5. The healthcare utilization predictors 5-6 years after baseline were mainly age, previous healthcare utilization and various symptoms and, in 1-2 and 3-4 years after baseline, age, various diagnostic groups and various physical variables. Thus healthcare utilization patterns seem to be similar for the different groups, but it is difficult to find universal predictors. This suggests that different variables should be considered, including both ADL and psychosocial variables, when trying to identify future healthcare users.

Measurement properties of the Minimal Insomnia Symptom Scale (MISS) in an elderly population in Sweden

BackgroundInsomnia is common among elderly people and associated with poor health. The Minimal Insomnia Symptom Scale (MISS) is a three item screening instrument that has been found to be psychometrically sound and capable of identifying insomnia in the general population (20-64 years). However, its measurement properties have not been studied in an elderly population. Our aim was to test the measurement properties of the MISS among people aged 65 + in Sweden, by replicating the original study in an elderly sample.MethodsData from a cross-sectional survey of 548 elderly individuals were analysed in terms of assumptions of summation of items, floor/ceiling effects, reliability and optimal cut-off score by means of ROC-curve analysis and compared with self-reported insomnia criteria.ResultsCorrected item-total correlations ranged between 0.64-0.70, floor/ceiling effects were 6.6/0.6% and reliability was 0.81. ROC analysis identified the optimal cut-off score as ≥7 (sensitivity, 0.93; specificity, 0.84; positive/negative predictive values, 0.256/0.995). Using this cut-off score, the prevalence of insomnia in the study sample was 21.7% and most frequent among women and the oldest old.ConclusionsData support the measurement properties of the MISS as a possible insomnia screening instrument for elderly persons. This study make evident that the MISS is useful for identifying elderly people with insomnia-like sleep problems. Further studies are needed to assess its usefulness in identifying clinically defined insomnia.

Factorial validity and invariance of the Life Satisfaction Index in older people across groups and time: Addressing the heterogeneity of age, functional ability, and depression

In the last decades, extensive research efforts have been directed at exploring life satisfaction in old age, and the Life Satisfaction Index A (LSIA) scale, developed by Neugarten et al. in the 1960s, is one of the most commonly used instruments. However, studies have focused on predicting and comparing changes in peoples life satisfaction without testing if the LSIA instrument is equally valid for different subgroups of people. The present study investigated the underlying dimensions of the LSIA in a Swedish population (n=1402) of people 60-96 years of age. The study also examined factorial invariance across age, gender, functional ability and depression during a six-year period. The results showed that while a five-factor solution of the LSIA did not exhibit an acceptable fit to the data, a three-factor solution did show a close fit. The two three-factor models that demonstrated the best fit showed invariance across gender and across time, but noninvariance across groups with different levels of reduced functional ability, depressive symptoms and age. These findings suggest that the psychometric properties of life satisfaction instruments like the LSIA need to be taken into consideration before drawing conclusions about life satisfaction when comparing older people of different ages and with different depression and function levels.
