Life satisfaction and mortality in elderly people: the Kangwha Cohort Study

The effect of socioeconomic status, depression, and diabetes symptoms severity on diabetes patient's life satisfaction in India

Evidence suggests that diabetes is on the rise in India, affecting many people's life satisfaction. Comprehensive estimation of life satisfaction among diabetes patients does not exist in the country. This study examined the effects of socioeconomic status, depression, and diabetes symptoms severity on the life satisfaction of diabetes patients by controlling various demographic variables. It was a cross-sectional study comprising 583 diabetes patients from Punjab, India. Patients were interviewed using a multi-stage purposeful random sampling method. Descriptive analysis and partial least squares structural equation modelling were used in the study to test the hypotheses. Results revealed that socioeconomic status, depression and diabetes symptoms severity significantly influence the life satisfaction of diabetes patients. A 1% drop in diabetes symptoms severity corresponds to a 0.849% increase in life satisfaction, whereas a 1% decrease in depression results in a 0.898% increase in life satisfaction. Patients with higher diabetes symptoms severity were coping with common mental disorders. Women reported higher diabetes symptoms severity and depression than men, resulting in lower life satisfaction. An experimental evaluation of the effects of socioeconomic status, depression and diabetes symptoms severity, and numerous demographic factors on life satisfaction was reported. The findings will help policymakers understand the problem associated with life satisfaction among diabetes patients in the country.

Happy people live longer because they are healthy people

OBJECTIVES

Higher levels of happiness are associated with longer life expectancy. Our study assessed the extent to which various factors explain the protective effect of happiness on all-cause mortality risk, and whether the association differs between older men and women.

METHODS

Using data from the Singapore Longitudinal Aging Studies (N = 6073) of community-dwelling older adults aged ≥ 55 years, we analyzed the association of baseline Likert score of happiness (1 = very sad to 5 = very happy) and mortality from mean 11.7 years of follow up. Cox regression models were used to assess the extent to which confounding risk factors attenuated the hazard ratio of association in the whole sample and sex-stratified analyses.

RESULTS

Happiness was significantly associated with lower mortality (p < .001) adjusted for age, sex and ethnicity: HR = 0.85 per integer score and HR = 0.57 for fairly-or-very happy versus fairly-or-very sad. The HR estimate (0.90 per integer score) was modestly attenuated (33.3%) in models that included socio-demographic and support, lifestyle or physical health and functioning factor, but remained statistically significant. The HR estimate (0.94 per integer score) was substantially attenuated (60%) and was insignificant in the model that included psychological health and functioning. Including all co-varying factors in the model resulted in statistically insignificant HR estimate (1.04 per integer score). Similar results were obtained for HR estimates for fairly-to-very happy versus fairly-to- very sad).

DISCUSSION

Much of the association between happiness and increased life expectancy could be explained by socio-demographic, lifestyle, health and functioning factors, and especially psychological health and functioning factors.

The Individual and Combined Effects of Social Networks and Loneliness on Life Satisfaction among Community-Dwelling Residing Older Adults: A Longitudinal Study

Social networks and loneliness are correlates of life satisfaction in old age. However, the evidence of the combined effects of social isolation and loneliness on life satisfaction is lacking; therefore, this study also aimed to investigate the combined effects of social networks and loneliness on life satisfaction in Malaysian older adults. Data from two waves of the "Neuroprotective Model for Healthy Longevity among Malaysian Older Adults" study were extracted. The first wave of data collection was completed in February 2013, while the second wave was conducted three years after the first wave. The main statistical analysis used was multivariable logistic regression. For individual effect, social networks (B = 0.375, p = 0.007), but not loneliness (B = -0.178, p = 0.368) significantly determined life satisfaction. Increasing social network size causes increasing life satisfaction. For combined effects, those in "the lone farmers" group (B = 0.279, p = 0.044) and "the majority" group (B = -0.413, p = 0.004) were linked to life satisfaction. Social engagement in older people is important for wellbeing in later life. Therefore, community programs and investing in a quality relationship should be encouraged to obtain adequate support and ultimately promote higher life satisfaction.

Satisfaction with life and associated factors among elderly people living in two cities in northwest Ethiopia: a community-based cross-sectional study

OBJECTIVE

This study aimed to determine the level of life satisfaction and identify associated factors among elderly people living in two cities in northwest Ethiopia.

DESIGN

Community-based cross-sectional study.

SETTING

Two cities in northwest Ethiopia (Gondar and Bahir Dar).

PARTICIPANTS

816 elderly people age 60 years and above living in Gondar and Bahir Dar, northwest Ethiopia. Systematic random sampling was used to select study participants.

MAIN OUTCOME MEASURE

Level of life satisfaction. Considering the mean and SD, three levels of satisfaction appeared to suffice as the basis for analysis and discussion: 23.5-34.4 dissatisfied, 34.5-56.5 averagely satisfied and 56.6-67.5 satisfied. Multivariable ordinal regression analysis was done to control the confounders. Since the outcome variable has an ordinal category, ordinal regression analysis is appropriate. A p≤0.05 and AOR (adjusted OR) with a 95% CI were considered to determine the statistically significant variables and strength of the association.

RESULTS

The mean age of the respondents was 68.2 years with an SD±7.2. The level of life satisfaction was: dissatisfied 17.2%, moderately satisfied 63.8% and well satisfied 19.0%. Overall, 45.8% (95% CI 42.2% to 49.2%) of the participants had a score equal to or above the mean. Regarding associated factors; retired current occupation (AOR=2.23, 95% CI 1.09 to 4.55), good self-rated health status (AOR=2.54, 95% CI 1.29 to 4.99), having no chronic disease (AOR=1.48, 95% CI 1.03 to 2.11), somewhat-good (AOR=2.15, 95% CI 1.12 to 4.13) and good (AOR=4.51, 95% CI 2.40 to 8.45) self-perception on ageing life, moderate functional impairment on daily living activities (AOR=5.43, 95% CI 1.81 to 16.24), high sense of coherence (AOR=3.80, 95% CI 2.04 to 7.08), house rent as a source of finance (AOR=2.60, 95% CI 1.49 to 4.52) and high perceived social support (AOR=2.13, 95% CI 1.44 to 3.16) had statistically significant association with the life satisfaction.

CONCLUSION

The life satisfaction level in our study group was lower than in some more highly developed countries. To improve the level of life satisfaction in Ethiopia, a holistic programme of nursing care for elderly people, particularly as concerns about their health and psychosocial conditions is crucial in both community and clinical settings.

Daytime napping and cardiovascular risk factors, cardiovascular disease, and mortality: A systematic review

Associations between night sleep duration and cardiovascular risk factors in adults have been well documented. However, the associations for daytime napping remain unclear. In this review, six databases were searched for eligible publications to April 8, 2022. A total of 11 articles were identified for umbrella review on the association of daytime napping with diabetes, metabolic syndrome (MetS), cardiovascular disease (CVD), and mortality in adults, 97 for systematic review on the association with CVD and several CVD risk factors. Our umbrella review showed that the associations of daytime napping with diabetes, MetS, CVD, and mortality in most meta-analyses were mainly supported by weak or suggestive evidence. Our systematic review showed that long daytime napping (≥1 h/d) was associated with higher odds of several CVD risk factors, CVD, and mortality, but no significant association was found between short daytime napping and most of the abovementioned outcomes. Our dose-response meta-analyses showed that daytime napping <30 min/d was not significantly associated with higher odds of most CVD risk factors and CVD among young and middle-aged adults. However, among older adults aged >60 years, we observed significant dose-response associations of daytime napping with higher odds of diabetes, dyslipidemia, MetS, and mortality starting from 0 min/d.

Relationship between Self-Reported Neighborhood Safety and Happiness and Life Satisfaction among Women in Low-Middle Income Countries

Measures related to subjective well-being such as perceived happiness and life satisfaction are becoming increasingly popular among health researchers due to their strong correlation with longevity and all-cause mortality. Previous studies have focused on the role of environmental safety on female empowerment. However, not much is known about the impact of environmental risk factors such as perceived safety on subjective well-being, especially in the low-middle-income countries (LMICs). The present study aims to investigate the association between self-reported safety and self-reported happiness and life satisfaction among women in selected LMICs in Asia and Africa. Methods: We analyzed cross-sectional data from eleven countries on 186,388 women aged 15–49 years from the sixth round of the Multiple Indicator Cluster Survey. The outcome measures were self-reported happiness and life satisfaction, and their associations with the safety indicators (i.e., feeling unsafe in the neighborhood and at home) were calculated using generalized ordered logit models by adjusting for relevant sociodemographic factors. Results: The highest percentage of feeling very unsafe both in the neighborhood (39.3%) and at home (26.5%) was reported in Iraq, while Tonga had the highest percentage of reporting both feeling very safe in the neighborhood (55.3%) and at home (54.9%). The odds of self-reported worsening life satisfaction were higher among women who reported feeling very unsafe in the neighborhood [OR = 1.43, 95% CI = 1.36,1.50] and at home [OR = 1.13, 95% CI = 1.08,1.19]. Feeling of being very unsafe in the neighborhood [OR = 1.16, 95% CI = 1.10,1.22] and at home [OR = 1.65, 95% CI = 1.57,1.74] also showed strong positive association with self-reported unhappiness. Conclusions: Our findings from eleven LMICs across Asia and Africa indicate that lack of environmental safety may negatively impact subjective well-being among women. Further research is necessary to explore the root causes of insecurity and design intervention programs aiming to promote women’s psychosocial health and well-being.

Transition milestones and life satisfaction at ages 25/26 among cohorts born in 1970 and 1989-90

The transition to adulthood has become more prolonged, complex, and risk-laden over the past two decades. These changes may contribute to the decline in wellbeing observed among young adults. We test the role of reaching different transition milestones on life satisfaction by ages 25-26 among men and women born 20 years apart in 1970 and 1989-90, using data from the 1970 British Cohort (men n = 3764, women n = 4568) and Next Steps (men n = 3246, women n = 4281) studies. We regressed life satisfaction on education, housing tenure, cohabitation with parents, economic activity, relationship status, and parenthood, and tested the role of changes in the prevalence and association of milestones in explaining cohort differences in life satisfaction using decomposition analyses. Home ownership, full-time employment, cohabitation with a partner, and marriage were robust predictors of life satisfaction in both cohorts. Comparing cohorts, the association of milestones with life satisfaction was stable among men but differed among women: in the later-born cohort, women no longer benefitted from higher education and further suffered from not being in full-time employment. The findings shed new light on the relationships between young adult transitions and life satisfaction during the third decade of life. These support the argument that decreases in wellbeing may be driven by changes in the prevalence and meaning of these milestones over time, particularly among women.

Effect of Brisk Walking on Health-Related Physical Fitness Balance and Life Satisfaction Among the Elderly: A Systematic Review

BACKGROUND

Although the elderly frequently engages in brisk walking as a form of exercise, little has been reported in the literature about the effect of brisk walking on health-related physical fitness, balance, and overall life satisfaction.

OBJECTIVES

The purpose of this systematic review is to determine the effect of brisk walking on the elderly's health-related physical fitness, balance, and life satisfaction.

DESIGN

We conducted a comprehensive search from the PubMed, Web of Science, Scopus, and SPORTDiscus databases from January to September 2021. We selected studies through PICOS and conducted a systematic literature review according to the PRISMA guidelines.

RESULTS

Thirteen studies met all criteria; 11 were classed as low risk of bias, while two were classified as high risk of bias. Generally, brisk walking has been shown to improve cardiorespiratory fitness, muscular strength, and body composition. Limited evidence was presented on flexibility, muscular endurance and development and life satisfaction, and there was conflicting evidence on balance. Moreover, evidence of restriction proves that high-intensity (80-85%) brisk walking is more effective than moderate-intensity (60-75%) brisk walking on the aerobic capacity of the elderly. Furthermore, there was less research conducted on males.

CONCLUSION

Brisk walking has been shown to improve cardiorespiratory fitness, muscular strength, and body composition. Other outcomes (balance, flexibility, muscular endurance, and life satisfaction) and the impact of the intensity of brisk walking on the elderly should be confirmed. Therefore, there remains insufficient research on brisk walking, while single brisk walking cannot meet requirements of elderly in terms of their health-related physical fitness, balance, and life satisfaction. Future research should aim to examine the effectiveness of combining several types of exercises to promote general health in the elderly, as the World Health Organization recommends. Unintelligible FITT (frequency, intensity, time, type) principles of brisk walking training should be trenched for the results of scientific and effective physical exercise.

Association of life satisfaction with disability-free survival: role of chronic diseases and healthy lifestyle

BACKGROUND

this article investigates the association between life satisfaction and disability-free survival, and explores the roles of chronic diseases and healthy lifestyle in this association.

METHOD

a cohort of 2,116 functionally independent adults aged ≥60 was followed up to 12 years. At baseline, life satisfaction was assessed with the Life Satisfaction Index A (LSI-A). Disability-free survival was defined as the survival till the first occurrence of either death, dementia or physical disability. Information on lifestyle factors was collected via questionnaire. Chronic diseases were ascertained through clinical examinations at baseline and each follow-up. Data were analysed using Cox proportional hazard regression models and Laplace regression.

RESULTS

over follow-up, 1,121 participants died, developed dementia, or became disabled. High LSI-A versus Low LSI-A had a lower risk of death, dementia and physical disability (hazard ratio [HR] 0.79, 95% confidence intervals [CI] 0.67-0.94), and had a longer disability-free period by 1.73 (95% CI 0.18-3.32) years. In mediation analysis, accumulation of chronic diseases mediated 17.8% of the association between LSI-A and disability-free survival. In joint effect analysis, participants with high LSI-A and a favourable lifestyle profile had a HR of 0.53 (95% CI 0.41-0.69) for the composite endpoint, and lived 3.2 (95% CI 1.35-5.11) disability-free years longer than those with low life satisfaction and an unfavourable lifestyle profile.

DISCUSSION

high life satisfaction is independently associated with longer disability-free survival. This association is partially mediated by a lower burden of chronic diseases and is reinforced by healthy lifestyle.

Relationship between financial well-being, life satisfaction, and cognitive function among low-income community-dwelling older adults: the moderating role of sex

BACKGROUND

Low financial well-being is a common predicament among older adults living in poverty. The existing literature suggests a correlation between financial well-being and mental health in old age. Therefore, this study aimed to identify the relationships among financial well-being, life satisfaction, and cognitive function among low-income older adults and to examine the moderating effect of sex on these relationships.

METHODS

This study involved 2004 nationally representative community-dwelling older Malaysians from the bottom 40% household income group. Financial well-being was assessed by the four-item financial satisfaction scale, while life satisfaction was measured by the Satisfaction with Life Scale. Cognitive function was measured by using the Malay version of the Mini-Mental State Examination. Hierarchical multiple regression was used as the prime method for statistical analysis.

RESULTS

Financial well-being was positively associated with life satisfaction and cognitive function. Sex moderated the relationship between financial well-being and life satisfaction but not between financial well-being and cognitive function.

CONCLUSIONS

Financial well-being and life satisfaction were strongly correlated among older women, although no gender difference was found for the relationship between financial well-being and cognitive function. It appears financial well-being strongly predicts mental health. As such, poverty eradication initiatives targeting low-income older adults should be implemented to sustain life satisfaction and cognitive function.

Impacts of multi-morbidity, hemoglobin levels, and frailty on functional disability of older adult residents of long-term care facilities: A structural equation analysis

AIM

Previous studies have focused on the relationship between multi-morbidity, frailty, and anemia or functional disability alone rather than in combination. This study aimed to explore the impacts of multi-morbidity, hemoglobin levels, and frailty on functional disability simultaneously in older adult residents of long-term care facilities.

METHODS

This was a cross-sectional study. Data were retrieved from the electronic health records of eight long-term care facilities. Data from a total of 352 subjects aged at least 60 years and residing in these facilities for at least 6 months were analysed. Analytic datasets included the Barthel Index of Activities of Daily Living, the Frailty Phenotype Criteria, the number of chronic diseases, hemoglobin levels, age, and gender.

RESULTS

The final model demonstrated acceptable goodness-of-fit indices, namely goodness-of-fit index, comparative fit index, and incremental fit index ≧0.90, root mean square error of approximation <0.08, and insignificance of χ² (P > 0.05). Frailty, multi-morbidity, and hemoglobin levels all had direct associations with functional disability (all P < 0.001). Hemoglobin levels had a direct association with frailty (ß = -0.11). Multi-morbidity had an indirect association (ß = 0.04) with functional disability through hemoglobin levels. Hemoglobin levels had an indirect association (ß = 0.05) with functional disability through frailty.

CONCLUSIONS

The impacts of multi-morbidity, hemoglobin levels, and frailty on functional disability were explored. A high-quality disease management program, interventions for the prevention of frailty, and the provision of continued education for staff about reducing progressive frailty and functional disability for older adult residents are recommended.

Cognitive leisure activity and all-cause mortality in older adults: a 4-year community-based cohort

BACKGROUND

Cognitive leisure activity, such as reading, playing mahjong or cards and computer use, is common among older adults in China. Previous studies suggest a negative correlation between cognitive leisure activity and cognitive impairment. However, the relationship between cognitive leisure activity and all-cause mortality has rarely been reported.

OBJECTIVES

This study aims to explore the relationships between cognitive leisure activity and all-cause mortality in a community-based older people cohort in China.

METHODS

The current study sample comprised 4003 community residents aged ≥60 y who were enrolled in June 2015, and were followed up every year from 2015 to 2018. Reading, playing mahjong or cards and computer use were measured by questionnaires and summed into a cognitive leisure activity index (CLAI) score. Time-Dependent Cox Regression Model and Kaplan-Meier survival analysis were used to examine the association of cognitive leisure activity with all-cause mortality.

RESULTS

During the 4-year follow-up of 4003 participants, 208 (5.2%) deaths were registered. Of all participants, 66.8, 26.7, 6.1 and 0.35% reported CLAI scores of 0, 1, 2 and 3, respectively. A strong association was noted between the CLA score and all-cause mortality (adjusted hazard ratio [HR] = 0.72, 95% confidence intervals [CI]: 0.54-0.97, P = 0.028). Stratified analysis suggested that a higher CLAI score was significantly associated with a decreased risk of all-cause mortality mainly among those who were male, aged ≥80 y, cognitively impaired, and not diagnosed with cancer (P < 0.05).

CONCLUSION

Cognitive leisure activity was positively associated with reduced risk of death from all cause among the older people in major city of China, which helped promote a comprehensive understanding of health characteristics at advanced ages.

Determinants of physical, mental and social well-being: a longitudinal environment-wide association study

BACKGROUND

Although the World Health Organization (WHO) has defined health as a state of physical, mental and social well-being, public health strategies have primarily focused on one domain of well-being. We sought to systematically and simultaneously identify and validate associations of behavioural patterns, psychosocial factors, mental and physical health conditions, access to and utilization of health care and anthropometrics with physical, mental and social well-being.

METHODS

We conducted a longitudinal environment-wide association study (EWAS) with a training and testing set approach, accounting for multiple testing using a false discovery rate control. We used multivariate multilevel regression to examine the association of each exposure at wave 1 with the three outcomes at wave 2 in the Hong Kong FAMILY Cohort (n = 10 484).

RESULTS

Out of 194 exposures, we identified and validated 14, 5 and 5 exposures that were individually associated with physical, mental and social well-being, respectively. We discovered three factors, namely depressive symptoms, life satisfaction and happiness, that were simultaneously associated with the three domains that define health.

CONCLUSIONS

These associations, if verified to be causal, could become intervention targets to holistically improve population health. Our findings provide empirical support for placing mental health at the forefront of the public health agenda, and also support recent calls to use life satisfaction and happiness to guide public policy.

The Role of Psychological and Social Well-being on Physical Function Trajectories in Older Adults

BACKGROUND

Psychological and social well-being are emerging as major determinants in preserving health in old age. We aimed to explore the association between these factors and the rate of decline in physical function over time in older adults.

METHODS

Data were gathered from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K). The study population consisted of 1,153 non-demented, community-dwelling men and women free from multimorbidity or impairments in basic or instrumental activities of daily living at baseline. They were followed over 12 years to capture the rate of decline in physical function, which was measured by combining data on walking speed, balance, and chair stands. The association between baseline psychological and social well-being and decline in physical function was estimated through linear mixed models, after multiple adjustments including personality and depressive symptoms.

RESULTS

Higher levels of psychological (β = .007; p = .037) and social (β = .008; p = .043) well-being were significantly associated with a decreased rate of decline in physical function over the follow-up. There was a significant three-way interaction between psychological well-being*time*sex (female vs male) (β = .015; p = .047), showing that a slower decline in physical function was observed only among women and not in men. The association was strongest for individuals with high levels of both psychological and social well-being (β = .012; p = .019).

CONCLUSION

High levels of psychological and social well-being may slow down the age-related decline in physical function, which confirms the complexity of older adults' health, but also points towards new preventative strategies.

Gender Differences in Factors Affecting Life Satisfaction of the Elderly with Multimorbidity in Korea

To enhance the life satisfaction of the elderly with multimorbidity, it is necessary to investigate the relevant factors and to examine the differences in factors according to gender. The aim of this study was to identify factors affecting life satisfaction of the elderly with multimorbidity in the community by gender in Korea. We analyzed data from 2140 participants with multimorbidity who were aged 65 or older and participated in the Korean Longitudinal Study of Ageing (KLoSA) in 2016. A multivariate linear regression analysis was conducted to examine the factors affecting life satisfaction among male and female older participants with multimorbidity. The most common pattern of multimorbidity of women was hypertension and arthritis/rheumatism, while that of men was hypertension and diabetes mellitus. Some factors, such as depression, exercise, and number of chronic diseases, affected both male and female participants, but others related to life satisfaction varied by gender. Therefore, it is necessary to consider the characteristics of multiple chronic diseases, and policy support should be provided in consideration of gender differences to improve the life satisfaction of the elderly.

The association between religious orientation and life satisfaction in older adults living with morbidity and multimorbidity: a gender perspective in Malaysia

BACKGROUND

Little is known about gender differences in the relationship between religious orientation and life satisfaction in older adults living with chronic disease(s). Therefore, the purpose of this article was to examine the moderating effect of gender on the association between religious orientation and life satisfaction in older adults living with morbidity and multimorbidity.

METHODS

The study involved 1790 community-dwelling older adults aged 60 and above living with at least one chronic medical condition. The Satisfaction with Life Scale and Revised Intrinsic/Extrinsic Religious Orientation Scale were used to measure life satisfaction and religious orientation. Moderated hierarchical multiple regression was used to test the moderation effect.

RESULTS

Results showed that while intrinsic religiosity was positively associated with life satisfaction, extrinsic religiosity was found to have a negative relationship with life satisfaction. Gender moderated the association between intrinsic religiosity and life satisfaction.

CONCLUSIONS

The findings suggested that the positive impact of intrinsic religiosity on life satisfaction was stronger in older women living with morbidity and multimorbidity. Healthcare practitioners can help disadvantaged older women in identifying their religious values and practices to improve their subjective wellbeing.

Being Happy and Becoming Happier as Independent Predictors of Physical Health and Mortality

OBJECTIVE

The present study tested preregistered predictions regarding the prospective associations between level and change in subjective well-being (SWB) and physical health.

METHODS

In two large longitudinal panel studies conducted in the United States (N = 3294) and Japan (N = 657), we used multilevel growth curve models to estimate level and change in components of SWB (i.e., life satisfaction, positive affect, and negative affect). Next, we used random intercepts and slopes to predict subsequent self-reported general health and number of chronic health conditions (in the United States and Japan) and mortality risk (in the United States).

RESULTS

Greater life satisfaction, higher positive affect, and lower negative affect were associated with better health (0.22 < |β values| < 0.46) and longer survival. Above and beyond SWB level, longitudinal increases in life satisfaction and positive affect and longitudinal decreases in negative affect were associated with better health (0.06 < |β values| < 0.20). Moreover, all three SWB components independently predicted health, and life satisfaction and negative affect independently predicted survival. The preregistration and analysis scripts are available at osf.io/mz9gy.

CONCLUSIONS

The present findings suggest that being happy and becoming happier across time are independently associated with better physical health in the United States and Japan.

Psychological correlates of multimorbidity and disability accumulation in older adults

BACKGROUND/OBJECTIVES

attitudes toward life and health are emerging as important psychological contributors to health heterogeneity in ageing. We aimed to explore whether different psychological factors were associated with the rate of chronic disease and disability accumulation over time.

DESIGN

population-based cohort study between 2001 and 2010.

SETTING

Swedish National study on aging and care in Kungsholmen.

SUBJECTS

adults aged 60 and older (N = 2293).

METHODS

linear mixed models were employed to study the association of life satisfaction, health outlook, resistance to illness, sickness orientation, and health worry with the rate of accumulation of chronic diseases and impaired basic and instrumental activities of daily living. Models were adjusted for demographic, clinical, social, personality and lifestyle factors. Analyses were repeated after excluding individuals with multimorbidity or disability at baseline.

RESULTS

high life satisfaction and positive health outlook were consistently associated with a lower rate of accumulation and progression of multimorbidity (β -0.064 95% confidence interval [CI] -0.116, -0.011; β -0.065 95% CI -0.121, -0.008, respectively) and disability (β -0.063 95% CI -0.098, -0.028; β -0.042 95% CI -0.079, -0.004, respectively) over time. This was true even for people without multimorbidity or disability at baseline and after adjusting for all covariates.

CONCLUSIONS

positive attitudes toward life in general and health in particular may be especially important in old age, when the cumulative effects of biological and environmental deficits lead to accelerated health decline. These findings should encourage researchers to use measures of psychological well-being to better understand the multifactorial and diverse process of ageing.

Does the Spanish version of the SWLS measure the same in Spain and Peru?

AIM

Satisfaction with life is a measure of protection in older adults. There lies the importance of providing quality instruments. The aim of the study was to evaluate the invariance of the life satisfaction scale (SWLS) in two samples of older adults in Spain and Peru.

METHOD

The participants were 857 older adults in Spain (mean age=68.23 years, SD=5.93) and 336 older adults in Peru (average age=72.42, SD=7.07). All multi-group confirmatory factor analyzes were estimated in Mplus 8.0.

RESULTS

The results indicate the presence of a strict invariance of the one-dimensional structure of the SWLS in samples of older adults in Spain and Peru, which allows for meaningful comparisons of latent means and covariances. Comparison of latent means showed small differences in the construct between the cultural groups.

CONCLUSIONS

The SWLS is a valid instrument for intercultural comparisons between Spanish and Peruvian population. The measurement invariance assessment contributes to a better understanding of life satisfaction in populations from different cultural contexts.

Socioeconomic Vulnerability, Mental Health, and Their Combined Effects on All-Cause Mortality in Koreans, over 45 Years: Analysis of Korean Longitudinal Study of Aging from 2006 to 2014

BACKGROUND

We evaluated the effects of socioeconomic factors and psychosocial factors, both individually and combined, on all-cause mortality risk (mortality risk).

METHODS

We conducted an 8-year (2006-2014) longitudinal analysis of 10,247 individuals who took part in the Korean Longitudinal Study of Aging, a nationwide survey of people aged 45-79 years. Socioeconomic vulnerability (SEV) was assessed with factors such as education, household income, commercial health insurance, and residential area. Mental health (MH) was assessed with factors such as depression, social engagement, and life satisfaction. The covariates were age, gender, marital status, cohabiting, number of chronic diseases, and health behaviors such as regular exercise, smoking, and alcohol intake. We used a Cox proportional hazard analysis to investigate the effects of SEV and MH on mortality risk and also to analyze the superimposed effects of SEV-MH on mortality risk.

RESULTS

After the controlling for the covariates, high SEV and negative MH were found to be strong predictors of all-cause mortality. The highest quartile of SEV (vs. lowest) had a 1.70 times greater mortality risk (hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.24-2.33) and the highest quartile of MH (vs. lowest) had a 2.13 times greater mortality risk (HR, 2.13; 95% CI, 1.72-2.64). Being in the highest quartile for both SEV and MH (vs. lowest) increased mortality risk more than 3 times (HR, 3.11; 95% CI, 2.20-4.40).

CONCLUSION

High SEV and negative MH were independently associated with increased mortality risk, and their superimposed effects were associated with an increased risk of mortality.

Happiness and Health

Research into the relationship between happiness and health is developing rapidly, exploring the possibility that impaired happiness is not only a consequence of ill-health but also a potential contributor to disease risk. Happiness encompasses several constructs, including affective well-being (feelings of joy and pleasure), eudaimonic well-being (sense of meaning and purpose in life), and evaluative well-being (life satisfaction). Happiness is generally associated with reduced mortality in prospective observational studies, albeit with several discrepant results. Confounding and reverse causation are major concerns. Associations with morbidity and disease prognosis have also been identified for a limited range of health conditions. The mechanisms potentially linking happiness with health include lifestyle factors, such as physical activity and dietary choice, and biological processes, involving neuroendocrine, inflammatory, and metabolic pathways. Interventions have yet to demonstrate substantial, sustained improvements in subjective well-being or direct impact on physical health outcomes. Nevertheless, this field shows great potential, with the promise of establishing a favorable effect on population health.

Psychological well-being and mortality: longitudinal findings from Lithuanian middle-aged and older adults study

BACKGROUND

The study aimed to examine whether after confounding by possible socio-demographic and other risk factors, psychological well-being is independently associated with reduced all-cause and cardiovascular mortality.

METHODS

Initial data were collected within the framework of the international project HAPIEE in 2006-2008. A random sample of 7115 individuals aged 45-72 years was screened. Deaths were evaluated by death register of Kaunas city (Lithuania) in a follow-up study till 2016. Psychological well-being was evaluated by a CASP-12 questionnaire. Socio-demographic, lifestyle, biologic factors and depressive symptoms were evaluated.

RESULTS

Age-adjusted survival curves revealed that psychological well-being predicts longevity in men and women (p < 0.001). After adjustment for many possible confounders psychological well-being was independently associated with all-cause mortality in men (HR 0.77; 95% CI 0.62-0.94) and women (HR 0.73; 95% CI 0.56-0.96). However, psychological well-being association with cardiovascular mortality attained statistical significance only in the women's group (HR 0.53; 95% CI 0.33-0.87), but not in men (HR 0.98; 95% CI 0.72-1.33).

CONCLUSIONS

Psychological well-being is an important predictor of longevity, controlling well-recognized risk factors such as age, education, cardiovascular diseases, social status, marital status, lifestyle and biological factors and depressive symptoms. Positive psychological well-being should be taken into account when screening older people to prevent negative health outcomes.

Emotional Well-Being and Public Health: Proposal for a Model National Initiative

In 2011, the National Prevention, Health Promotion, and Public Health Council named mental and emotional well-being as 1 of 7 priority areas for the National Prevention Strategy. In this article, we discuss emotional well-being as a scientific concept and its relevance to public health. We review evidence that supports the association between emotional well-being and health. We propose a national emotional well-being initiative and describe its 6 components: systematic measurement of emotional well-being, identification of the drivers of emotional well-being, formation of partnerships with diverse stakeholders, implementation and dissemination of evidence-based interventions to promote emotional well-being and its drivers, development of public health messaging, and identification of and strategies to address disparities in emotional well-being and its drivers. Finally, we discuss ways in which a national emotional well-being initiative would complement current public health efforts and the potential challenges to such an initiative.

Levels of and changes in life satisfaction predict mortality hazards: Disentangling the role of physical health, perceived control, and social orientation

It is well documented that well-being typically evinces precipitous decrements at the end of life. However, research has primarily taken a postdictive approach by knowing the outcome (date of death) and aligning, in retrospect, how well-being has changed for people with documented death events. In the present study, we made use of a predictive approach by examining whether and how levels of and changes in life satisfaction prospectively predict mortality hazards and delineate the role of contributing factors, including health, perceived control, and social orientation. To do so, we applied shared parameter growth-survival models to 20-year longitudinal data from 10,597 participants (n = 1,560 [15%] deceased; age at baseline: M = 44 years, SD = 17, range = 18-98 years) from the national German Socio-Economic Panel Study. Our findings showed that lower levels and steeper declines of life satisfaction each uniquely predicted higher mortality risks. Results also revealed moderating effects of age and perceived control: Life satisfaction levels and changes had stronger predictive effects for mortality hazards among older adults. Perceived control was associated with lower mortality hazards; however, this effect was diminished for those who experienced accelerated life satisfaction decline. Variance decomposition suggests that predictive effects of life satisfaction trajectories were partially unique (3%-6%) and partially shared with physical health, perceived control, and social orientation (17%-19%). Our discussion focuses on the strengths and challenges of a predictive approach to link developmental changes (in life satisfaction) to mortality hazards, and considers implications of our findings for healthy aging.

Life satisfaction and inflammation in couples: an actor-partner analysis

Life satisfaction has been linked to lower cardiovascular disease mortality. However, much less is known about the biological mechanisms linking life satisfaction to physical health. In addition, the dyadic context of life satisfaction has not been considered despite increasing evidence that partners influence each other in health-relevant ways. These questions were addressed with 94 married couples who completed measures of life satisfaction and had their blood drawn for determination of interleukin-6 (IL-6) and C-reactive protein (CRP). Actor-partner models showed that higher actor levels of life satisfaction predicted lower levels of IL-6 and CRP (p's < .05), whereas partner levels of life satisfaction did not predict any measure of inflammation. The actor results were not mediated by marital satisfaction or health behaviors. Finally, no actor × partner interactions were significant and these links were not moderated by marital satisfaction. These data highlight inflammation as a potentially important biological mechanism linking actor reports of life satisfaction to lower cardiovascular mortality.

Do past stressful life events and personal control beliefs predict subjective wellbeing in old age? Evidence from a Spanish nationwide representative sample

It has been widely corroborated that recent stressful life events could impact wellbeing; nevertheless, it is not clear whether stressful situations experienced in the past and the individual resources used to deal with them influence older adults’ wellbeing. This study aims to analyse the influence of stressful past events and personal control beliefs, or the extent to which people believe they can control or influence their environment in order to achieve desired outcomes, on negative affect and domain-specific life satisfaction in a cross-sectional sample of 1,177 Spanish people age 50 years and older. For this purpose, the measurement of ten stressful past events, perceived control beliefs, negative affect and life satisfaction were obtained. Preliminary analyses showed that domain-specific life satisfaction grouped into two factors: internal and external life satisfaction. The results of the partial least squares structural equation model indicated that stressful events and control beliefs have an impact on both negative affect and life satisfaction in old age. Stressful past events had a negative effect on life satisfaction, while control beliefs were positively associated with negative affect. The model was able to predict the variance of internal life satisfaction at 37.5 per cent.

The Impact of Subjective Well-being on Mortality: A Meta-Analysis of Longitudinal Studies in the General Population

OBJECTIVE

The aims of the study were to assess whether subjective well-being is a protective factor for mortality in the general population and to analyze the differential impact of evaluative, experienced, and eudaimonic well-being.

METHODS

Systematic review of articles in the PsycINFO, Web of Science, and PubMed databases. Data on the studies' characteristics, quality, and the effects of variables were extracted. A meta-analysis was conducted on the studies included in the systematic review.

RESULTS

A total of 62 articles that investigated mortality in general populations, involving 1,259,949 participants, were found, and added to those considered in a previously published review (n = 14). The meta-analysis showed that subjective well-being was a protective factor for mortality (pooled hazard ratio = 0.920; 95% confidence interval = 0.905-0.934). Although the impact of subjective well-being on survival was significant in both men and women, it was slightly more protective in men. The three aspects of subjective well-being were significant protective factors for mortality. The high level of heterogeneity and the evidences of publication bias may reduce the generalizability of these findings.

CONCLUSIONS

Our results suggest that subjective well-being is associated with a decreased risk of mortality. Longitudinal studies examining changing levels of well-being and their relationship to longevity would be required to establish a cause-effect relationship. Establishing such a causal relationship would strengthen the case for policy interventions to improve the population subjective well-being to produce longevity gains combined with optimizing quality of life.

The relationships among Muslim Uyghur and Kazakh disabled elders' life satisfaction, activity of daily living, and informal family caregiver's burden, depression, and life satisfaction in far western China: A structural equation model

1 Hypothesis Disabled elders' activities of daily living, caregiver burden, caregiver depression, and caregivers' life satisfaction are significantly related to the life satisfaction of elderly people with disability. 2 Hypothesis There are direct and indirect effects between the life satisfaction of elders, disabled elders' activities of daily living, and family caregivers' factors. This study explored the interrelationships of disabled elders' life satisfaction and activities of daily living, caregivers' factors (burden, depression, and life satisfaction) through a structural equation model. In total, 621 dyads of disabled elders and informal family caregivers completed questionnaires during face-to-face interviews in Xinjiang Uyghur Autonomous Region from September 2013 to January 2014. Activity of daily living exerted a direct effect on life satisfaction of disabled elders and 30.4% indirect effect through caregivers' factors. Caregiver burden had a 60.0% direct effect on life satisfaction of disabled elders and a 40.0% indirect effect through the caregiver depression. Caregiver depression showed 76% direct effect on life satisfaction of disabled elders and 24% indirect effect through caregivers' life satisfaction. Direct relationships between activity of daily living and caregiver burden, caregiver burden and caregiver depression, and caregiver depression and caregivers' life satisfaction were observed. Activity of daily living had a 91.3% indirect effect on caregiver depression mediated by caregiver burden; caregiver burden had a 40.0% indirect effect on caregivers' life satisfaction mediated by caregiver depression. Results provide useful information for nurses and policymakers and shed light on the need to consider caregivers' factors in improving care recipients' life satisfaction.

Psychometric properties of the Satisfaction with Life Scale (SWLS): secondary analysis of the Mexican Health and Aging Study

BACKGROUND

The Satisfaction with Life Scale (SWLS) has been widely used and has proven to be a valid and reliable instrument for assessing satisfaction with life in diverse population groups, however, research on satisfaction with life and validation of different measuring instruments in Mexican adults is still lacking. The objective was to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS) in a representative sample of Mexican adults.

METHODS

This is a methodological study to evaluate a satisfaction with life scale in a sample of 13,220 Mexican adults 50 years of age or older from the 2012 Mexican Health and Aging Study. The scale's reliability (internal consistency) was analysed using Cronbach's alpha and inter-item correlations. An exploratory factor analysis was also performed. Known-groups validity was evaluated comparing good-health and bad-health participants. Comorbidity, perceived financial situation, self-reported general health, depression symptoms, and social support were included to evaluate the validity between these measures and the total score of the scale using Spearman's correlations.

RESULTS

The analysis of the scale's reliability showed good internal consistency (α = 0.74). The exploratory factor analysis confirmed the existence of a unique factor structure that explained 54% of the variance. SWLS was related to depression, perceived health, financial situation, and social support, and these relations were all statistically significant (P < .01). There was significant difference in life satisfaction between the good- and bad-health groups.

CONCLUSIONS

Results show good internal consistency and construct validity of the SWLS. These results are comparable with results from previous studies. Meeting the study's objective to validate the scale, the results show that the Spanish version of the SWLS is a reliable and valid measure of satisfaction with life in the Mexican context.

Multidimensional construct of life satisfaction in older adults in Korea: a six-year follow-up study

Background

Aging raises wide-ranging issues within social, economic, welfare, and health care systems. Life satisfaction (LS) is regarded as an indicator of quality of life which, in turn, is associated with mortality and morbidity in older adults. The objective of this study was to identify the relevant predictors of life satisfaction and to investigate changes in a multidimensional construct of LS over time.

Methods

This analysis utilized data from the large-scale, nationally representative Korean Retirement and Income Study (KReIS), a longitudinal survey conducted biennially from 2005 to 2011. Outcome measures were degree of satisfaction with health, economic status, housing, neighbor relationships, and family relationships. GEE models were used to investigate changes in satisfaction within each of the five domains.

Results

Of a total 3531 individuals aged 65 or older, 2083 (59%) were women, and the mean age was 72 (s.d = ±6) years. The majority had a spouse (60.8%) and lived in a rural area (58%). Analysis showed that physical and mental health were consistently and significantly associated with satisfaction in each of the domains after adjusting for potential confounders. Living in a rural area and living with a spouse were related to satisfaction with economic, housing, family relationships, and neighbor relationships compared to living in urban areas and living without a spouse; the only outcome that did not show relationship to these predictors was health satisfaction. Female and rural residents reported greater economic satisfaction compared to male and urban residents. Living in an apartment was associated with 1.32 times greater odds of economic satisfaction compared to living in a detached house (95% CI: 1.14–1.53; p < 0.0001). Economic satisfaction was also 1.62 times more likely among individuals living with a spouse compared to single households (95% CI: 1.35–1.96; p < 0.0001). Financial stress index value was found to be a significant predictor of satisfaction with family relationships.

Conclusions

Our study indicates that a single domain of LS or overall LS will miss many important aspects of LS as age-related LS is multi-faceted and complicated. While most studies focus on overall life satisfaction, considering life satisfaction as multidimensional is essential to gaining a complete picture.

Impact of physical and mental health on life satisfaction in old age: a population based observational study

Background

It is widely assumed that poor health lowers life satisfaction when ageing. Yet, research suggests this relationship is not straightforward. This study investigated how older people evaluate their life when facing disease and disabilities.

Methods

The Leiden 85-plus Study, a prospectively followed cohort of a cohort of a middle-sized city in the Netherlands, all aged 85 years, that was age-representative of the general population, was used. Those with severe cognitive dysfunction were excluded (n = 501). Comorbidities, physical performance, cognitive function, functional status, residual lifespan, depressive symptoms and experienced loneliness were measured during home visits. Life satisfaction was self-reported with Cantril’s ladder. All analyses were performed using regression analysis.

Results

Participants reported high life satisfaction (median 8 out of 10 points) despite having representative levels of disease and disability. Comorbidity, low cognitive function, and residual lifespan as markers of health were not associated with life satisfaction. Poor physical performance and low functional status were weakly but significantly associated with lower life satisfaction (p < 0.05 respectively p < 0.001), but significance was lost after adjustment for depressive symptoms and perceived loneliness. Depressive symptoms and perceived loneliness were strongly related to lower life satisfaction (both p < 0.001), even after adjustment for physical health characteristics.

Conclusion

Poor physical health was hardly related to lower life satisfaction, whereas poor mental health was strongly related to lower life satisfaction. This indicates that mental health has a greater impact on life satisfaction at old age than physical health, and that physical health is less relevant for a satisfactory old age.

Life Satisfaction Index among Elderly People Residing in Gorgan and Its Correlation with Certain Demographic Factors in 2013

BACKGROUND

Aging is a universal phenomenon that will present itself as a dominant social and welfare challenge.

AIM

This study was to examine life satisfaction among people residing in Gorgan and its correlation with certain demographic factors in 2013.

METHODS

A total of 250 elder people were selected for the study through the convenience sampling during 4 months. Data collected through life satisfaction index-A (LSIA). This instrument consists of 5 subscales, including, zest for life, resolution and fortitude, congruence between desired and achieved goals, positive self-concept and mood tone. The Multiple Linear Regression analysis was used in order to determine factors influencing the overall LSIA.

RESULTS

The overall LSIA score was 22.1 ± 7.5 with the maximum and minimum mean scores pertaining to the resolution and fortitude (6.1 ± 2.5) and the positive self-concept (3.1 ± 1.2) subscales, respectively. Level of education, type of living and gender were variables influencing the overall LSIA (P<0.05).

CONCLUSION

Given the overall LSIA, it appears that future plans for this age group should be seriously revised along with cultural plans for promoting reverence for old age in the general public.

The Relationship between Levels of Physical Activity and Quality of Life among Students of the University of the Third Age

AIM

The assessment of quality of life (QoL) among elderly people is of great importance when preparing health care programmes for this social group. Many researchers indicate that poor health is less frequently observed in senior citizens who display levels of physical activity (PA) prescribed by WHO. The aim of the study was to investigate the relationship between the level of PA among students of the University of the Third Age (U3A) and their self-assessment concerning their QoL.

METHODS

The research sample consisted of 131 students from three U3A in West Pomeranian Voivodeship in Poland. PA was assessed with the aid of a short Polish version of the International Physical Activity Questionnaire (IPAQ). The assessment of QoL was conducted with the use of a Polish version of the WHO Quality of Life--BREF instrument (WHOQOL-BREF).

RESULTS

The present study has shown that highly active U3A students declare high QoL in the psychological and social domains more often than other respondents.

CONCLUSION

The level of PA recommended by WHO has a positive impact on the perceived QoL. Possible differences are visible mostly in the assessment of different domains of life in relation to the presented levels of PA.

Associations of sleep duration and sleep quality with life satisfaction in elderly Chinese: The mediating role of depression

This study investigated whether sleep duration and quality were related to life satisfaction (LS) among older Chinese adults and whether depression mediated those relationships. Cross-sectional data from the aging arm of the Rugao Longevity and Aging Study were used. Sleep duration, sleep quality, depression, LS and covariates were analyzed using logistic regressions. To assess the potential mediation of depression on the association between sleep duration and quality and LS, Aroian tests were used. Of 1756 older Chinese adults aged 70-84 years, 90.7% of the men and 83.3% of the women reported being satisfied with their lives. After adjusting for covariates, older adults who slept ≤6h per night were more likely to suffer from life dissatisfaction compared with those who slept 7-8h (OR=2.67, 95% CI 1.86-3.79), and individuals who slept poorly were almost 2 times (OR=2.91, 95% CI 2.16-3.91) more likely to have life dissatisfaction. The Aroian tests confirmed that these relationships were partially mediated by depression (p<0.001). Between short sleep and LS, the mediating effect of depression accounted for 13.9% of the total effects. Moreover, the mediating effect of depression on the association between sleep quality and LS was 13.3%. Short sleep duration and poor sleep quality were inversely associated with LS, and the relationships were partially mediated by depression. Our study suggests that both sleep and depression status are important factors for LS among the elderly.

Does Low Body Mass Index Matter? Relationship between Body Mass Index and Subjective Well-Being among Long-Lived Women over 95 Years of Age

OBJECTIVES

To examine the relationship between body mass index (BMI) and subjective well-being (SWB) among long-lived women over 95 years of age and evaluate whether this relationship is mediated by functional ability.

DESIGN

Retrospective cohort study.

SETTING

Data from the Rugao longevity cohort, a population-based study in Rugao, China.

PARTICIPANTS

A sample of 342 long-lived women (mean age 97.4 ± 2.1, range 95-107) whose SWB and other covariates were available were included in this study.

MEASUREMENTS

BMI was calculated as weight in kilograms divided by height in meters-squared (kg/m(2)). SWB was measured by life satisfaction (LS), positive affect (PA), negative affect (NA) and affect balance (AB). Functional ability was assessed by the Katz Index of Activities of Daily Living (ADL).

RESULTS

According to BMI classification standards for China, the underweight group had lower levels of LS than the normal and overweight groups (28.62 vs. 30.51 and 31.57, respectively; p<.05). Correlation analysis showed that BMI was significantly related to LS (r = 0.166, p<.01). The strength of the BMI and LS association was diminished when ADL was included in the general linear regression models. Mediation analysis revealed that ADL mediated this relationship (effect size = 22.6%). We did not observe significant associations of BMI with other SWB components (PA, NA, and AB).

CONCLUSION

For long-lived women, low BMI, rather than elevated BMI, is an indicator of poor psychological well-being. The findings call for public health awareness about low body weight in long-lived women, especially in those with physical disabilities when focusing on quality of life.

Social Support Buffers the Impact of Depressive Symptoms on Life Satisfaction in Old Age

OBJECTIVES

Life satisfaction is an important component of overall well-being. Decline in life satisfaction is related to many adverse health outcomes including mortality.

METHODS

We investigate the association of various psychosocial and health-related factors to life satisfaction in 237 non-demented community-dwelling older adults.

RESULTS

Lower levels of depressive symptoms, less perceived stress, higher levels of social support, and better self-perceived general health were significantly associated with higher life satisfaction. Social support buffered the adverse impact of depressive symptoms on life satisfaction where more depressive symptoms were associated with much lower life satisfaction at low levels of social support than at high levels of social support.

DISCUSSION

We discuss study implications, future research directions, and possible interventions that involve boosting social support in at-risk older adults.

Subjective well-being and hookah use among adults in the United States: A nationally-representative sample

BACKGROUND

Using a nationally-representative dataset of adults 18-30 years old in the United States, this study examined the relationship between hookah use and subjective well-being. Levels of sadness, happiness, tiredness, pain, and stress were compared between persons who have used hookah and those who have not.

METHODS

Data were merged from the Tobacco Use Supplement of the Current Population Survey, the American Time Use Survey, and the Subjective Well-being Supplement to the American Time Use Survey for the years 2010-2012 for persons 18-30 years old (n=1147). Wald tests were used to compare mean differences in subjective well-being between hookah users and non-users. Lastly, multivariable regression was used to determine whether there were significant differences in subjective well-being between hookah users and non-users, controlling for demographic factors, self-perceived health, and cigarette smoking.

RESULTS

The lifetime prevalence rate of hookah use was 5.2% among 18-30 year olds. Hookah users reported higher levels of stress and sadness than non-users. These relationships remained significant after controlling for demographic characteristics, self-perceived health, and cigarette use. The results were robust to the use of different statistical models, different age cut-offs, the inclusion of additional covariates (such as income and population density), and separate analyses by sex.

CONCLUSIONS

Hookah use is an emerging public health issue associated with increased levels of stress and sadness. Similar to cigarette use, healthcare providers may consider expanding their screening tests to include hookah use. Public policy geared toward greater prevention and control of hookah use is also recommended.

In nonagenarians, acute kidney injury predicts in-hospital mortality, while heart failure predicts hospital length of stay

BACKGROUND/AIMS

The elderly constitute an increasing proportion of admitted patients worldwide. We investigate the determinants of hospital length of stay and outcomes in patients aged 90 years and older.

METHODS

We retrospectively analyzed all admitted patients aged >90 years from the general medical wards in a tertiary referral medical center between August 31, 2009 and August 31, 2012. Patients' clinical characteristics, admission diagnosis, concomitant illnesses at admission, and discharge diagnosis were collected. Each patient was followed until discharge or death. Multivariate logistic regression analysis was utilized to study factors associated with longer hospital length of stay (>7 days) and in-hospital mortality.

RESULTS

A total of 283 nonagenarian in-patients were recruited, with 118 (41.7%) hospitalized longer than one week. Nonagenarians admitted with pneumonia (p = 0.04) and those with lower Barthel Index (p = 0.012) were more likely to be hospitalized longer than one week. Multivariate logistic regression analysis revealed that patients with lower Barthel Index (odds ratio [OR] 0.98; p = 0.021) and those with heart failure (OR 3.05; p = 0.046) had hospital stays >7 days, while patients with lower Barthel Index (OR 0.93; p = 0.005), main admission nephrologic diagnosis (OR 4.83; p = 0.016) or acute kidney injury (OR 30.7; p = 0.007) had higher in-hospital mortality.

CONCLUSION

In nonagenarians, presence of heart failure at admission was associated with longer hospital length of stay, while acute kidney injury at admission predicted higher hospitalization mortality. Poorer functional status was associated with both prolonged admission and higher in-hospital mortality.
