Subjective social isolation or loneliness in older adults residing in social housing in Ontario: a cross-sectional study.

Older adults face greater risk of social isolation, but the extent of social isolation among low-income older adults living in social housing is unknown. This study aims to explore the rate of, and risk factors contributing to, subjective social isolation or loneliness among older adults in social housing. We conducted a cross-sectional study of data collected from a community program held in the common rooms of 55 social housing buildings in 14 communities across Ontario, Canada, from May 2018 to April 2019. Participants were program attendees aged 55 years and older who resided in the buildings. Program implementers assessed social isolation using the 3-Item Loneliness Scale from the University of California, Los Angeles and risk factors using common primary care screening tools. We extracted data for this study from the program database. We compared the rate of social isolation to Canadian Community Health Survey data using a 1-sample χ2 test, and evaluated associations between risk factors and social isolation using univariate and multivariate logistic regressions. We included 806 residents in 30 buildings for older adults and 25 mixed-tenant buildings. Based on the 3-Item UCLA Loneliness Scale, 161 (20.0%) of the 806 participants were socially isolated. For those aged 65 and older, the rate of social isolation was nearly twice that observed in the same age group of the general population (36.1% v. 19.6%; p < 0.001). Risk factors were age (65-84 yr v. 55-64 yr adjusted odds ratio [OR] 1.99, 95% confidence interval [CI] 1.01-3.93), alcohol consumption (adjusted OR 2.45, 95% CI 1.09-5.54), anxiety or depression (adjusted OR 6.05, 95% CI 3.65-10.03) and income insecurity (adjusted OR 2.10, 95% CI 1.24-3.53). Protective factors were having at least 1 chronic cardiometabolic disease (adjusted OR 0.44, 95% CI 0.24-0.80), being physically active (adjusted OR 0.47, 95% CI 0.30-0.73) and having good to excellent general health (adjusted OR 0.60, 95% CI 0.39-0.90). The high rate of social isolation in low-income older adults living in social housing compared with the general population is concerning. Structural barriers could prevent engagement in social activities or maintenance of social support, especially for older adults with income insecurity and anxiety or depression; interventions are needed to reduce subjective social isolation in this population.

Social Isolation and Loneliness Among San Francisco Bay Area Older Adults During the COVID-19 Shelter-in-Place Orders.

Physical distancing during the COVID-19 pandemic may have unintended, detrimental effects on social isolation and loneliness among older adults. Our objectives were to investigate (1) experiences of social isolation and loneliness during shelter-in-place orders, and (2) unmet health needs related to changes in social interactions. Mixed-methods longitudinal phone-based survey administered every 2 weeks. Two community sites and an academic geriatrics outpatient clinical practice. A total of 151 community-dwelling older adults. We measured social isolation using a six-item modified Duke Social Support Index, social interaction subscale, that included assessments of video-based and Internet-based socializing. Measures of loneliness included self-reported worsened loneliness due to the COVID-19 pandemic and loneliness severity based on the three-item University of California, Los Angeles (UCLA) Loneliness Scale. Participants were invited to share open-ended comments about their social experiences. Participants were on average aged 75 years (standard deviation = 10), 50% had hearing or vision impairment, 64% lived alone, and 26% had difficulty bathing. Participants reported social isolation in 40% of interviews, 76% reported minimal video-based socializing, and 42% minimal Internet-based socializing. Socially isolated participants reported difficulty finding help with functional needs including bathing (20% vs 55%; P = .04). More than half (54%) of the participants reported worsened loneliness due to COVID-19 that was associated with worsened depression (62% vs 9%; P < .001) and anxiety (57% vs 9%; P < .001). Rates of loneliness improved on average by time since shelter-in-place orders (4-6 weeks: 46% vs 13-15 weeks: 27%; P = .009), however, loneliness persisted or worsened for a subgroup of participants. Open-ended responses revealed challenges faced by the subgroup experiencing persistent loneliness including poor emotional coping and discomfort with new technologies. Many older adults are adjusting to COVID-19 restrictions since the start of shelter-in-place orders. Additional steps are critically needed to address the psychological suffering and unmet medical needs of those with persistent loneliness or barriers to technology-based social interaction.

The association between loneliness and depressive symptoms among adults aged 50 years and older: a 12-year population-based cohort study.

Loneliness is experienced by a third of older adults in the UK and is a modifiable potential risk factor for depressive symptoms. It is unclear how the association between loneliness and depressive symptoms persists over time, and whether it is independent of related social constructs and genetic confounders. We aimed to investigate the association between loneliness and depressive symptoms, assessed on multiple occasions during 12 years of follow-up, in a large, nationally representative cohort of adults aged 50 years and older in England. We did a longitudinal study using seven waves of data that were collected once every 2 years between 2004 and 2017, from adults aged 50 years and older in the English Longitudinal Study of Ageing (ELSA). The exposure was loneliness at baseline (wave two), measured with the short 1980 revision of the University of California, Los Angeles Loneliness Scale (R-UCLA). The primary outcome was a score indicating severity of depression measured at six subsequent timepoints (waves three to eight), using the eight-item version of the Centre for Epidemiologic Studies Depression Scale (CES-D). Analyses were linear multilevel regressions, before and after adjusting for social isolation, social support, polygenic risk scores, and other sociodemographic and health-related confounders. The secondary outcome was depression diagnosis, measured using a binary version of the CES-D. 4211 (46%) of 9171 eligible participants had complete data on exposure, outcome, and confounders, and were included in our complete case sample. After all adjustments, a 1-point increase in loneliness score was associated with a 0·16 (95% CI 0·13-0·19) increase in depressive symptom severity score (averaged across all follow-ups). We estimated a population attributable fraction for depression associated with loneliness of 18% (95% CI 12-24) at 1 year of follow-up and 11% (3-19) at the final follow-up (wave eight), suggesting that 11-18% of cases of depression could potentially be prevented if loneliness were eliminated. Associations between loneliness and depressive symptoms remained after 12 years of follow-up, although effect sizes were smaller with longer follow-up. Irrespective of other social experiences, higher loneliness scores at baseline were associated with higher depression symptom severity scores during 12 years of follow-up among adults aged 50 years and older. Interventions that reduce loneliness could prevent or reduce depression in older adults, which presents a growing public health problem worldwide.
