Loneliness in the elderly is associated with the use of psychotropic drugs

Are Sensory Experiences of One's Deceased Spouse Associated with Bereavement-Related Distress?

Following late-life spousal bereavement, sensory and quasi-sensory experiences of the deceased (SED) are commonly reported. This longitudinal study examined SED among 310 older widowed adults 6-10 (T1) and 18-20 (T2) months post loss. Reports of SED in the first 6-10 months after loss were associated with higher symptom levels of prolonged grief, post-traumatic stress, and loneliness at T1. Experiencers of SED were more likely to experience symptoms of prolonged grief and post-traumatic stress above cut-off scores at T1. Importantly, only a minority of the experiencers of SED displayed these elevated levels of bereavement-related distress. In addition, employing multi-level-modeling, a similar trajectory of decreasing bereavement-related distress over time was found for both experiencers and non-experiencers of SED. We argue that SED may be one of several potential reactions to bereavement, which should not be seen as an indicator of grief complications per se.

Gender-specific factors associated with case complexity in middle-aged and older adults-Evidence from a large population-based study

OBJECTIVES

To investigate gender-specific factors associated with case complexity in a population-based sample of middle-aged and older adults using a holistic approach to complexity.

METHODS

Data were derived from the 8-year follow-up home visits of the ESTHER study-a German population-based study in middle-aged and older adults. Cross-sectional analyses were conducted for 2932 persons (aged 57-84). Complexity was assessed by the well-established INTERMED for the elderly interview, which uses a holistic approach to the definition of case complexity. The association between various bio-psycho-social variables and case complexity was analyzed using gender-specific logistic regression models, adjusted for sociodemographic factors (age, marital status, education).

RESULTS

Prevalence of complexity was 8.3% with significantly higher prevalence in female (10.6%) compared to male (5.8%) participants (p < 0.001). Variables associated with increased odds for complexity in both, women and men were: being divorced (odds ratio [OR] women: 1.86, 95% CI 1.05-3.30; OR men: 3.19, 1.25-8.12), higher total somatic morbidity (women: 1.08, 1.04-1.12; men: 1.06, 1.02-1.11), higher depression severity (women: 1.34, 1.28-1.40; men: 1.35, 1.27-1.44), and higher loneliness scores (women: 1.19, 1.05-1.36; men: 1.23, 1.03-1.47). Women (but not men) with obesity (Body mass index [BMI] ≥30) had higher odds (1.79, 1.11-2.89) for being complex compared to those with a BMI <25. High oxidative stress measured by derivatives of reactive oxygen metabolites in serum was associated with 2.02 (1.09-3.74) higher odds for complexity only in men.

CONCLUSIONS

This study provides epidemiological evidence on gender differences in prevalence and factors associated with case complexity in middle-aged and older adults. Moreover, this study adds to the holistic understanding of complexity by identifying novel variables linked to complexity among middle-aged and older individuals. These factors include loneliness for both genders, and high oxidative stress for men. These findings should be confirmed in future longitudinal studies.

Relationship between Loneliness and Mild Behavioral Impairment: Validation of the Japanese Version of the MBI Checklist and a Cross-Sectional Study

Background

Mild behavioral impairment (MBI) and loneliness are associated with cognitive decline and an increased risk of dementia.

Objective

Our aim was to examine the validity of the Japanese version of the MBI checklist (MBI-C) and investigate the relationship between loneliness and MBI.

Methods

The participants in this cross-sectional study included 5 cognitively normal persons and 75 persons with mild cognitive impairment. MBI-C and the revised University of California at Los Angeles loneliness scale (LS) were used to assess MBI and loneliness, respectively. Diagnostic performance of MBI-C was examined using receiver operating characteristic analysis. The relationship between MBI-C and LS was examined using multiple linear regression in 67 subjects who were assessed with both scales, with MBI-C total or domain score as the dependent variable and LS as the independent variable, adjusted for age, gender, living situation, presence of visual and hearing impairment, and Mini-Mental State Examination score.

Results

Per the Youden index, in this mostly MCI sample, the optimal MBI-C cut-off score was 5.5 with sensitivity 0.917 and specificity 0.949. In multiple linear regression analysis, LS score was detected as a significant predictor of MBI-C total scores, and MBI-C decreased motivation, affective dysregulation, and abnormal thought and perception scores.

Conclusions

The caregiver-rated Japanese MBI-C has excellent diagnostic performance. Loneliness is associated with a greater MBI burden, especially in the decreased motivation, affective dysregulation, and abnormal thought and perception domains. Interventions for loneliness in older people may have the potential to improve MBI.

Correlations between Dementia and Loneliness

This review describes associations between dementia and loneliness on the neurobiological and epidemiological levels according to the recent body of literature. The aim of this study was to highlight major lines of research in this field. Sociocognitive skills and social interactions present complex interdependencies with dementia which may be explained by two theories. According to the first one, not sufficiently engaging in social or cognitive activities results in brain atrophy. The second one claims that brain neurogenesis and synaptic density are being increased by social connections. The relationship between loneliness and dementia could be mediated by sensory loss, including hearing and visual impairment, as well as depression and psychotic symptoms. Loneliness itself might cause a depletion in sensory and cognitive stimulation which results in a decrease in neural reserve. Certain changes in the structures of the brain caused by loneliness were found in imaging examination. Loneliness appears to be a crucial risk factor for dementia in recent times due to the modern lifestyle and consequences of the outbreak of COVID-19. Additional studies are required to understand more completely the key tenets of this topic and therefore to improve the prevention and treatment of dementia.

Gender-specific association of loneliness and health care use in community-dwelling older adults

BACKGROUND

Loneliness in older adults is common, particularly in women. In this article, gender differences in the association of loneliness and health care use are investigated in a large sample of community-dwelling older adults.

METHODS

Data of 2525 persons (ages 55-85 years)-participants of the fourth follow- up (2011-2014) of the ESTHER study- were analyzed. Loneliness and health care use were assessed by study doctors in the course of a home visit. Gender-specific regression models with Gamma-distribution were performed using loneliness as independent variable to predict outpatient health care use, adjusted for demographic variables.

RESULTS

In older women, lonely persons were shown to have significantly more visits to general practitioners and mental health care providers in a three-month period compared to less lonely persons (p = .005). The survey found that outpatient health care use was positively associated with loneliness, multimorbidity, and mental illness in older women but not in older men. Older men had significantly more contact with inpatient care in comparison to women (p = .02).

CONCLUSIONS

It is important to consider gender when analyzing inpatient and outpatient health care use in older persons. In older women loneliness is associated with increased use of outpatient services.

En route to flourishing - a longitudinal mixed methods study of long-term unemployed citizens in an interdisciplinary rehabilitation program

BACKGROUND

Interdisciplinary rehabilitation programmes (IRP) are used in municipality settings to assist unemployed citizens with complex health and/or life issues. Individually tailored IRP activities help people develop their personal working life skills and increase their chances of re-entering the work force. The aims of this paper were to describe citizens' wellbeing in terms of health aspects, explore the impact of stressful life events on wellbeing and obtain understanding of how IRP activities affect the participants' development towards future employment.

METHODS

A mixed methods exploratory approach has been used. For data collection a quantitative longitudinal survey (baseline and 1-year follow-up) and qualitative interviews were conducted. Descriptive statistics were used for the analysis of survey data, while the data material from interviews was analysed using directed content analysis. Results were discussed with the theory of flourishing as a framework to develop understanding.

RESULTS

At baseline, 146 respondents (71% females) filled in the survey and seven participants were interviewed. The analysis of survey data and interviews revealed five themes: (1) Stressful life events, (2) Positive emotions - how IRP-activities positively impacted wellbeing and physical capacity, (3) Appreciation of engagement, (4) Relationships, and (5) Meaning and optimal functioning. Results showed that IRP participants from the outset experienced high general pain intensity as well as distress, anxiety and depression. Life events relating both to physical health and work life were significant for their wellbeing. IRP activities supported participants' positive development towards future employment in ways that were specific to each individual.

CONCLUSIONS

From this study it can be derived that participants' development took place around self-acceptance, acceptance by others, physical capacity, psychological resources and capacity to balance engagement to cultivate the best version of themselves. In future programmes, it may be emphasized that participants' interest may be an important driver for wellbeing and future employment.

Illicit Drug Use in Older Adults: An Invisible Epidemic?

Illicit drug use/misuse among older adults is understudied, although current trends point to older adults being the fastest-growing segment in the United States and other developed countries. There is a need for further insight into drug use patterns in older adults, who face their own set of socioeconomic, medical, and psychiatric problems. We reviewed the literature for data related to use/misuse of heroin and stimulants (cocaine, amphetamines, and methamphetamines) among people over the age of 40 years. We focused on prevalence rates of use/misuse of these substances, comorbidities, diagnostic challenges, screening tools, and treatment recommendations specific to the geriatric population.

Dual trajectories of loneliness and depression and their baseline correlates over a 14-year follow-up period in older adults: Results from a nationally representative sample in Taiwan

AIMS

To explore the codevelopment between loneliness and depression in older adults, and to identify its potential baseline individual, family and extrafamilial correlates.

BACKGROUND

The number of older adults around the world has steadily increased over the last decades. Later life is a particularly vulnerable life stage due to multiple unfavourable conditions, and mental health in this stage appears to become an inescapable issue. Previous research has found the cross-sectional association between loneliness and depression, but their codevelopment has been understudied. Therefore, exploring the codevelopment and its correlates has significant implications for prevention and healthcare professionals.

DESIGN

A longitudinal follow-up study.

METHODS

The study used nationally representative data over a 14-year follow-up period from the Taiwan Longitudinal Study on Ageing focused on Taiwanese aged 60 years and above (n = 4049). Group-based trajectory modelling, group-based dual-trajectory modelling and multinomial logistic regression were the primary analytical methods.

RESULTS

We identified three distinct dual trajectories of loneliness and depression: longitudinal low-frequency lonely depressed (29.3%), longitudinal moderate-frequency lonely depressed (59.4%) and longitudinal high-frequency lonely depressed (11.3%). After considering several demographic and background characteristics, difficulty in physical functioning, number of physical symptoms and diseases, sleep quality and number of child deaths were found to be significantly associated.

CONCLUSION

Across the three identified dual-trajectory groups, they all showed a stable loneliness frequency pattern over time; however, the moderate-frequency group and high-frequency group both had a trajectory of increasing depression. It seems that depression tends to change over time in a worsening direction, especially for those with a certain frequency of loneliness. Furthermore, differences in individual and family correlates were found across the groups.

IMPLICATIONS FOR PRACTICE

Interventions focusing on the specific factors may help hinder coexisting loneliness and depression, and have implications for developing health promotion strategies and chronic disease care plans.

Poor social support and loneliness in chronic headache: Prevalence and effect modifiers

OBJECTIVE

To explore the prevalence of poor social support and loneliness among people with chronic headache, and how these might be effect modifiers in the relationships between chronic headache and stress, medication overuse, and self-rated health.

BACKGROUND

Poor social support and loneliness are consistently linked to worse health outcomes. There are few epidemiologic studies on their effect on headache.

METHODS

The Danish Capital Region Health Survey, a cross-sectional survey, was conducted in 2017. Participants were asked about headache, pain medication use, social support, loneliness, perceived stress, and self-rated health. Data were accessed from sociodemographic registers. Logistic regression analyses were performed to test for effect modification.

RESULTS

The response rate was 52.6% (55,185 respondents) and was representative of the target population. People with chronic headache were more likely to report poor social support and loneliness compared to those without chronic headache (p < 0.0001 for both). Odds ratios for the combination of chronic headache and poor social support were very high for stress (odds ratio 8.1), medication overuse (odds ratio 21.9), and poor self-rated health (odds ratio 10.2) compared to those without chronic headache and with good social support. Those who reported both chronic headache and loneliness had a very high odds ratio for stress (odds ratio 14.4), medication overuse (odds ratio 20.1), and poor self-rated health (odds ratio 15.9) compared to those without chronic headache and low loneliness score. When adjusted for sociodemographic factors, poor social support and loneliness were not significant effect modifiers in almost all these associations. Loneliness was a significant effect modifier in the association between chronic headache and medication overuse, but exerted greater effect among those who did not report they were lonely.

CONCLUSION

Poor social support and loneliness were prevalent among people with chronic headache. The combination of chronic headache and poor social support or loneliness showed higher odds ratios for stress, medication overuse, and poor self-rated health compared to those with good social support and low loneliness scores. The effect of loneliness in the relationship between chronic headache and medication overuse warrants further study.

"Surviving the Violence, Humiliation, and Loneliness Means Getting High": Violence, Loneliness, and Health of Female Sex Workers

Sex workers are particularly vulnerable to violence, isolation, and stigmatization. This study uses the theory of loneliness to explore the relations among violence, self-esteem, loneliness, health, and drug use. Specifically, this study tested a model in which loneliness mediates the relationship between situational (violence) and characterological (self-esteem) loneliness factors and physical and psychological health and drug abuse. The study sample consisted of 146 sex workers from one region of Spain, recruited through the purposive sampling method. Partial least squares (PLS) path modeling has been employed to test the hypothesis. The findings of this study suggest that two kinds of violence (physical and psychological) have a direct and positive influence on loneliness, so that higher levels of violence increase loneliness, while self-esteem has a protector role on loneliness. Loneliness has a direct and negative impact on psychological and physical health, and determines an increase in drug use, which, in turn, decreases both physical and psychological health. The results support, among other points, that policy makers and sex worker service programs need to be aware of how loneliness plays a role in the health and risk behavior of sex workers. Society has an important role to improve sex workers' health and minimize their risk behavior.

Importance of loneliness in behavioral and psychological symptoms of dementia

OBJECTIVES

Loneliness is considered to be a crucial factor in mental health of elderly people. However, the effects of loneliness on behavioral and psychological symptoms of dementia (BPSD) have not been fully examined. The aim of this study was to investigate whether loneliness in patients with dementia is related to BPSD.

METHODS

A total of 152 patients with dementia were assessed using the Neuropsychiatric Inventory (NPI-12) and the revised University of California at Los Angeles (UCLA) loneliness scale. Spearman correlation analysis and Mann-Whitney U-tests were used to examine factors associated with the revised UCLA loneliness scale. Logistic regression analysis with a forced entry method was performed to identify risk factors for BPSD.

RESULTS

The revised UCLA loneliness scale score was not significantly associated with age, years of education, mini-mental state examination (MMSE) score, gender, living status, visual impairment, hearing impairment, and marital status. However, this score was a significant predictor of NPI delusion and hallucination subscale scores and Geriatric Depression Scale-15 score. The MMSE score was a significant predictor of NPI anxiety and apathy subscale scores.

CONCLUSIONS

Loneliness is a risk factor for BPSD, especially for depressive symptoms and psychosis. Paying attention to loneliness in patients with dementia will help medical staff to intervene in psychiatric symptoms of these patients at an early stage.

Loneliness, worries, anxiety, and precautionary behaviours in response to the COVID-19 pandemic: A longitudinal analysis of 200,000 Western and Northern Europeans

BACKGROUND

In response to the COVID-19 pandemic, governments around the world instituted various public-health measures. Our project aimed to highlight the most significant similarities and differences in key mental-health indicators between four Western and Northern European countries, and identify the population subgroups with the poorest mental-health outcomes during the first months of the pandemic.

METHODS

We analysed time-series survey data of 205,084 individuals from seven studies from Denmark, France, the Netherlands, and the UK to assess the impact of the pandemic and associated lockdowns. All analyses focused on the initial lockdown phase (March-July 2020). The main outcomes were loneliness, anxiety, and COVID-19-related worries and precautionary behaviours.

FINDINGS

COVID-19-related worries were consistently high in each country but decreased during the gradual reopening phases. While only 7% of the respondents reported high levels of loneliness in the Netherlands, percentages were higher in the rest of the three countries (13-18%). In all four countries, younger individuals and individuals with a history of mental illness expressed the highest levels of loneliness.

INTERPRETATION

The pandemic and associated country lockdowns had a major impact on the mental health of populations, and certain subgroups should be closely followed to prevent negative long-term consequences. Younger individuals and individuals with a history of mental illness would benefit from tailored public-health interventions to prevent or counteract the negative effects of the pandemic. Individuals across Western and Northern Europe have thus far responded in psychologically similar ways despite differences in government approaches to the pandemic.

The association between loneliness and medication use in older adults

BACKGROUND

Loneliness is common in older adults, and it is associated with unhealthy behaviours, including substance use. We evaluated the association between loneliness and self-reported use of opioids and benzodiazepines in older adults.

METHODS

We used data from the Canadian Community Health Survey's 'Healthy Aging' sub-survey and included adults 65 years or older who administered their own medications. We classified individuals as lonely if they scored 6 or more on the three -item University of California, Los Angeles's Loneliness Scale. We used multinomial logistic regression models, adjusting for demographics and self-reported comorbidities, to describe the association between loneliness and daily or occasional use of opioids, benzodiazepines and non-opioid analgesics. We also explored the association between loneliness and polypharmacy.

RESULTS

Our cohort included 15,302 older adults, of whom 2,096 (13.7%) were classified as lonely. Daily use of opioids (4.1%) and benzodiazepines (1.7%) were less common than daily use of non-opioid analgesics (33.9%). Lonely older adults had higher daily use of opioids (odds ratio [OR] 1.61, 1.31-1.98) and benzodiazepines (OR 1.66, 1.21-2.28), but not non-opioid analgesics (OR 1.05, 0.92-1.19). Loneliness was not associated with occasional use of opioids, benzodiazepines or non-opioid analgesics in older adults, but was associated with polypharmacy (OR 1.27, 1.06-1.52).

CONCLUSIONS

Loneliness in older adults is associated with increased daily use of opioids and benzodiazepines. Further research should evaluate patient- and physician-level factors that mediate this association, and develop strategies to mitigate loneliness and its attendant adverse outcomes.

The Impact of Resilience and Extraversion on Psychological Distress, Loneliness, and Boredom During the COVID-19 Pandemic: A Follow-Up Study Among the General Population of Tyrol, Austria

Background: The Covid-19 pandemic and related measures represent an enormous burden on mental health. The aim of this study was to investigate longitudinal changes in psychological distress, loneliness, boredom, and resilience over the course of the pandemic and to examine the associations between resilience and extraversion at baseline (summer 2020) and psychological distress, loneliness, and boredom at 5-month-follow-up. Methods: Residents of Tyrol (≥18a) completed an online survey on psychological distress, loneliness, boredom, resilience, and extraversion by using the Brief-Symptom-Checklist, the Three-Item Loneliness Scale, the Multidimensional State Boredom Scale-Short Form (MSBS-SF), the Resilience Scale, and the Extraversion subscale of the Big Five Inventory. Results: Of the 961 baseline participants, 384 took part in the follow-up survey. The percentage of study participants with striking psychological distress remained the same. Similarly, resilience did not change from baseline to follow-up, whereas the number of those experiencing moderate loneliness increased significantly. In contrast, at follow-up, severe loneliness was detected in significantly less people. Boredom decreased significantly over time. A moderate negative association was detected between baseline resilience and psychological distress, loneliness, and boredom at follow-up, and a weak but still significant negative association between extraversion and these outcomes. Discussion: These findings indicate that a subset of the general population consistently suffers from high levels of psychological distress and point to the protective effects of resilience and extraversion in this context. They reemphasize the importance of prevention and mitigation strategies to address these public health problems.

Psychological Distress, Loneliness, and Boredom Among the General Population of Tyrol, Austria During the COVID-19 Pandemic

Background: COVID-19-related mental health problems are considered a public health challenge. The aim of this study was to investigate psychological distress, loneliness, and boredom among the general population of the federal state of Tyrol, Austria. Methods: Residents of Tyrol aged ≥ 18 years were recruited via dissemination of a link through social media and other advertisements and invited to complete an online survey from June 26th to August 20th, 2020. Next to the collection of sociodemographic and COVID-19 related variables the Brief Symptom Checklist (BSCL), the Three-Item Loneliness Scale (TILS), and the Multidimensional State Boredom Scale-Short Form (MSBS-SF) were used to assess psychological distress, loneliness, and boredom. Results: 961 participants took part in the survey (68.3% woman). Of these, 14.4% were burdened from psychological distress (BSCL), 22.6% reached a TILS score ≥ 7 and were therefore classified as severely lonely, and boredom levels lay by a mean of 25.9 ± 11.0 points in the MSBS-SF (range: 7-56). Women, singles, low-income people as well as those who were unemployed were significantly more often affected by all of the selected outcomes compared to the remaining sample and they had significantly more frequently consumed alcohol or other substances since the outbreak of the pandemic in order to feel better. In addition, young and middle-aged adults were particularly burdened by loneliness and boredom. Discussion: Our findings identify vulnerable groups and factors associated with higher psychological distress, loneliness, and boredom in the context of the pandemic. In order to prevent mental health problems it will be critical to identify options of maintaining social contacts and remaining active despite pandemic-related restrictions.

Social Network and Risk of Poor Sleep Outcomes in Older Adults: Results from a Spanish Prospective Cohort Study

BACKGROUND

Not having social support has been associated with poor sleep, but most prospective studies were based on social support in the workplace, did not account for baseline sleep characteristics or did not assess sleep duration. Moreover, no previous research has evaluated the relationship between social network and sleep outcomes in an older Spanish population.

METHODS

1444 individuals aged ≥60 years were followed between 2012 and 2015. At baseline (2012), a poor social network index (SNI) was computed by summing the following dichotomous indicators: not being married; living alone; not having daily contact with family, friends or neighbors; being alone ≥8h/day; lacking someone to go for a walk with; not having emotional support; lacking instrumental support. Higher values in SNI indicate less social support. In 2012 and 2015, information was collected on sleep duration (hours/day) and on symptoms of sleep disturbance: bad overall sleep; difficulty falling asleep, awakening during nighttime, early awakening with difficulty getting back to sleep, use of sleeping pills, feeling restless in the morning, being asleep at daytime, and having an Epworth Sleepiness Scale>10. Poor sleep duration was defined as short (<6 h) or long (>9 h) nighttime sleep, and poor sleep quality as having ≥4 indicators of sleep disturbance. Linear or logistic regression models were used to assess the relationship of SNI with changes in sleep duration and in number of sleep disturbance indicators, or with the risk of developing poor nighttime sleep or poor sleep quality.

RESULTS

Compared to individuals in the lowest (best) quartile of the SNI in 2012, those in the second, third and fourth quartiles, respectively, displayed a mean (95%confidence interval [95% CI]) change of 2.32 (-7.58-12.22), -2.70 (-13.19-7.79) and -13.04 (-23.41- -2.67) minutes in sleep duration from 2012 to 2015; p for trend=0.02. A 1-point increase in the SNI at baseline was associated with an increased risk of short nighttime sleep (Odds Ratio [OR] and 95% CI: 1.22 (1.05-1.42)), poor sleep quality (OR: 1.13; 95% CI: 1.00-1.30), and of the indicator of sleep disturbance "early awakening with difficulty getting back to sleep" (OR: 1.20; 95% CI: 1.07-1.35).

CONCLUSION

A poorer social network is associated with a higher risk of short sleep and poor sleep quality in older adults.

Classification of loneliness using the T-ILS: Is it as simple as it seems?

Student well-being is a growing issue in higher education, and assessment of the prevalence of conditions as loneliness is therefore important. In higher education and population surveys the Three-Item Loneliness Scale (T-ILS) is used increasingly. The T-ILS is attractive for large multi-subject surveys, as it consists of only three items (derived from the UCLA Loneliness Scale). Several ways of classifying persons as lonely based on T-ILS scores exist: dichotomous and trichotomous classification schemes and use of sum scores with rising levels indicating more loneliness. The question remains whether T-ILS scores are comparable across the different population groups where they are used or across groups of students in the higher education system. The aim was to investigate whether the T-ILS suffers from differential item functioning (DIF) that might change the loneliness classification among higher education students, using a large sample just admitted to 22 different academy profession degree programs in Denmark (N = 3,757). DIF was tested relative to degree program, age groups and gender. The framework of graphical loglinear Rasch models was applied, as this allows for adjustment of sum scores for uniform DIF, and thus for assessment of whether DIF might change the classification. Two items showed DIF relative to degree program and gender, and adjusting for this DIF changed the classification for some subgroups. The consequences were negligible when using a dichotomous classification and larger when using a trichotomous classification. Therefore, trichotomous classification should be used with caution unless suitable adjustments for DIF are done prior to classification.

Predictors of Loneliness by Age Decade: Study of Psychological and Environmental Factors in 2,843 Community-Dwelling Americans Aged 20-69 Years

OBJECTIVE

Loneliness is a prevalent and serious public health problem due to its effects on health, well-being, and longevity. Understanding correlates of loneliness is critical for guiding efforts toward the development of evidence-based strategies for prevention and intervention. Considering that patterns of association between age and loneliness vary, the present study sought to examine age-related differences in risk and protective factors for loneliness.

METHODS

Correlates of loneliness were examined through a large web-based survey of 2,843 participants (aged 20-69 years) from across the United States from April 10, 2019, through May 10, 2019. Participants completed the 4-item UCLA Loneliness Scale, San Diego Wisdom Scale (with the following subscales measuring components of wisdom: Prosocial Behaviors, Emotional Regulation, Self-Reflection, Acceptance of Divergent Values, Decisiveness, and Social Advising), and other scales measuring psychosocial variables. Multivariate regression analyses were conducted to identify the best model of loneliness and examine potential age-related differences.

RESULTS

Age demonstrated a nonlinear quadratic relationship with loneliness (Wald statistic = 5.48, P = .019); levels were highest in the 20s and lowest in the 60s with another peak in the mid-40s. Across all decades, loneliness was associated with not having a spouse or partner (P < .001), sleep disturbance (P < .02), lower prosocial behaviors (P < .001), and smaller social network (P < .001). Lower social self-efficacy (P < .001) and higher anxiety (P < .005) were associated with worse loneliness in all age decades, except the 60s. Loneliness was uniquely associated with decisiveness in the 50s (P = .012) and with education (P = .046) and memory complaints (P = .013) in the 60s.

CONCLUSIONS

Our findings identify several potentially modifiable targets related to loneliness, including several aspects of wisdom and social self-efficacy. Differential predictors at different decades suggest a need for a personalized and nuanced prioritizing of prevention and intervention targets.

Evidence for underuse and overuse of antidepressants in older adults: Results of a large population-based study

OBJECTIVES

Depression is common among elderly people. However, diagnosis and adequate treatment is frequently difficult. Research on underuse and overuse of antidepressants in elderly persons is scarce. This study investigates the utilization and appropriateness of pharmacological and psychological depression treatment in a large cohort of community-dwelling adults.

METHODS

A subsample of 3117 participants (aged 55-85 y) of the third follow-up (2008-2010) of the large population-based German ESTHER study was included. Depression was assessed using the eight-item Patient Health Questionnaire (PHQ-8). In the course of a home visit, study doctors collected complete information on medication. Logistic regression analyses were conducted to determine the relationship of depression with both underuse and overuse of antidepressants. The analyses were then adjusted for socioeconomic variables, psychosomatic comorbidities, and motivation to seek help.

RESULTS

One hundred sixty-three participants (5.2%; 95% confidence interval [CI], 4.5-6.1) fulfilled the criteria for major depression. Underuse of antidepressants was present in 126 depressed participants (77.3%; 70.1-83.5). Persons who were motivated to seek help, who had an established depression diagnosis, or who were taking more than five different medications had lower odds of underuse. Anxiety was associated with higher odds for underuse. Overuse of antidepressants (prescription without clinical indication) was found in 96 cases (41.7%; 35.3-48.4) of all antidepressant prescriptions.

CONCLUSIONS

Depression treatment in older adults is frequently insufficient; it appears to depend on diagnosis as well as the patients' motivation to seek help. Education regarding the diagnosis of depression in the elderly as well as guidelines for appropriate treatment is needed.

A short intervention targeting psychosomatic care in older adults with complex health care needs-results of a randomized controlled trial

OBJECTIVE

The aim of this randomized controlled trial (RCT) was to assess the efficacy of a short intervention targeting psychosomatic care in older adults with complex health care needs.

METHODS

Participants were recruited in the frame of the 11-year follow-up of a large population-based study by means of the INTERMED interview. The INTERMED interview is an integrative assessment method to identify bio-psycho-social health care needs. Persons with high health care needs (interview score ≥ 17) were invited to take part. Participants were randomized with a 1:1 ratio to a control and an intervention group. The intervention group received a home visit conducted by a doctor trained in psychosomatic medicine. The primary hypothesis stated that the intervention group would have a better outcome with respect to health related quality of life (HRQOL) measured by the 12-item short-form health survey (mental component score, MCS) 6 months after randomization (T1). Secondary outcomes were physical HRQOL, health care needs, depression, anxiety, and somatic symptom severity.

RESULTS

In total, 175 participants were included. At the three-year follow-up (T2), 97 participants (55.4%) were included. At T1, we did not find a difference regarding MCS between the intervention and control groups. At T2, the intervention group showed significantly lower health care needs compared with the control group. Regarding HRQOL, depression, and somatic symptom severity the two groups did not differ at T2.

CONCLUSIONS

The primary hypothesis was not confirmed. However, results indicate that a short intervention with complex patients could lead to reduced bio-psycho-social health care needs.

Loneliness and Illicit Opioid Use Among Methadone Maintenance Treatment Patients

Background: Loneliness has been linked to greater substance use, especially among women. Yet little is known about how loneliness is associated with treatment outcomes for patients with opioid use disorder (OUD). Objectives: We evaluated how patient reports of using illicit opioids (i.e. heroin or non-prescription pain medications) are linked to perceptions of loneliness in a sample of adults receiving methadone maintenance treatment (MMT), and whether this link varies by gender. Methods: Participants for this cross-sectional observational study included 371 MMT patients aged 18 and older drawn from four opioid treatment programs in Southern New England and the Pacific Northwest. Patients completed a self-administered survey assessing sociodemographic and health information, loneliness, illicit opioid use, and MMT characteristics. Logistic regressions were estimated to examine the link between patient odds of illicit opioid use in the past month and perceived loneliness. Results: Patient gender moderated the association between illicit opioid use and loneliness such that severe loneliness was associated with higher odds of using illicit opioids among women (OR = 3.00, 95% CI [1.19, 7.57], p=.020) but lower odds of using illicit opioids among men (OR = 0.35, 95% CI [0.14, 0.87], p=.024), accounting for age, marital status, work status, depressive symptoms, and MMT characteristics (treatment episode, treatment duration, and methadone dose). Conclusions/importance: This study underscores the importance of considering loneliness in the management of OUD. Routine clinical care and treatment may benefit from strategies to build and sustain social connections that support long-term recovery among MMT patients.

Predictors of antidepressant use in the English population: analysis of the Adult Psychiatric Morbidity Survey

Objectives

The rate of antidepressant use in the United Kingdom has outpaced diagnostic increases in the prevalence of depression. Research has suggested that personal and socioeconomic risk factors may be contributing to antidepressant use. To date, few studies have addressed these possible contributions. Thus, this study aimed to assess the relative strength of personal, socioeconomic and trauma-related risk factors in predicting antidepressant use.

Methods

Data were derived from the Adult Psychiatric Morbidity Survey (n=7403), a nationally representative household sample of adults residing in England in 2007. A multivariate binary logistic regression model was developed to assess the associations between personal, socioeconomic and trauma-related risk factors and current antidepressant use.

Results

The strongest predictor of current antidepressant use was meeting the criteria for an ICD-10 depressive episode [odds ratio (OR)=9.04]. Other significant predictors of antidepressant use in this analysis included English as first language (OR=3.45), female gender (OR=1.98), unemployment (OR=1.82) and childhood sexual abuse (OR=1.53).

Conclusions

Several personal, socioeconomic and trauma-related factors significantly contributed to antidepressant use in the multivariate model specified. These findings aid our understanding of the broader context of antidepressant use in the United Kingdom.

"Where are all the lonely people?" A population-based study of high-risk groups across the life span

BACKGROUND

Loneliness is a prevalent and urgent public health issue. Optimal planning of community approaches to loneliness requires a differentiated understanding of loneliness across the life span. We identified groups at high risk of loneliness by exploring the relationship between loneliness and socio-demographic and health-related factors across multiple age groups.

METHODS

This was a combined population-based questionnaire survey and register data study based on a representative sample, including 33,285 Danish individuals aged 16-102 years. Loneliness was measured using the Three-Item Loneliness Scale.

RESULTS

The relation between loneliness and age took a shallow U-shaped distribution. Ethnic minority status, receiving disability pensions or being unemployed, living alone, prolonged mental disorder, and psychiatric treatment were strongly associated with severe loneliness. Socio-demographic and health-related factors were associated with an increased risk of severe loneliness in specific age groups. Being female, having a low educational level and living in a deprived area were only associated with loneliness in adolescence/emerging adulthood. Receiving disability pensions and living alone (i.e., divorced), on the other hand, were strongly associated with loneliness in early and middle adulthood and young-old age.

CONCLUSION

Ethnic minority status, living alone, and prolonged mental disorder may well be key factors in determining the generic level of loneliness in a given population. Other conditions are associated with an increased risk of severe loneliness in specific age groups and may moderate the age-loneliness relation. These findings may help to identify populations within communities at risk of loneliness and thereby support the implementation of policies and public health interventions across the life span.
