Loneliness in older adult mental health services during the COVID‐19 pandemic and before: Associations with disability, functioning and pharmacotherapy

Abstract

Objectives Loneliness is associated with psychiatric morbidity. Restrictions placed on the population during the first COVID‐19 lockdown may have disproportionately affected older adults, possibly through increasing loneliness. We sought to investigate this by examining loneliness in referrals to mental health of older adults (MHOA) services during the first UK COVID‐19 lockdown. Methods Referrals to MHOA services from a large South London catchment area were identified for the 16‐week period of the UK lockdown starting in March 2020 and for the corresponding period in 2019. A natural language processing algorithm identified loneliness in the patients' records. We applied logistic regression models adjusted for age, gender, ethnicity and diagnosis, to examine associations of loneliness in the study population. Results 1991 referrals were identified, 56.9% of whom were female, with a mean age of 77.9 years. Only 26.9% occurred during the 2020 lockdown, but with a higher prevalence of loneliness (22.0 vs. 17.7%, p = 0.028). In the whole sample, loneliness was associated with non‐accidental self‐injury (Odds ratio [OR]: 1.65), depressed mood (OR: 1.73), psychotic symptoms (OR: 1.65), relationship problems (OR: 1.49), problems with daytime activities (OR: 1.36), and antidepressant use (OR: 2.11). During lockdown, loneliness was associated with non‐accidental self‐injury (OR: 2.52), problem drinking or drug‐taking (OR 2.33), and antidepressant use (OR 2.10). Conclusions Loneliness is associated with more severe symptoms of affective illness, worse functional problems and increased use of antidepressant medication in older adults. During lockdown, loneliness in referrals to MHOA services increased and was associated with increased risk‐taking behaviour. Loneliness is a potential modifiable risk factor for mental illness, and efforts to minimise it in older adults should be prioritised as we emerge from the pandemic.

The Impact of COVID-19 on Self-Reported Substance Use, Well-Being, and Functioning Among United States Veterans: A Cross-Sectional Study

“…The strong association between loneliness and both physical and mental health functioning was also particularly important. This aligns with pre-pandemic evidence showing social support being associated with decreased all-cause mortality, cardiovascular disease, depression, and anxiety ( Leigh-Hunt et al, 2017 ), and pandemic-specific research showing loneliness as a strong predictor of worse functioning, affective illness, and non-accidental self-injury ( Greig et al, 2022 ). As loneliness can lead to worse outcomes, effective interventions that are also consistent with COVID-19 infection control and social distancing measures, such as those suggested in the systematic review by Williams et al (2021) , may be of particular importance in veteran treatment.…”

Distress, loneliness, and mental health during the COVID‐19 pandemic: Test of the extension of the Evolutionary Theory of Loneliness

“…The COVID‐19 pandemic has the potential to enhance this negative “feedback loop” since it reinforces withdrawal and distancing. This is especially true for individuals with limited health since they might lack strategies or opportunities for compensation (Greig et al, 2021 ). The ELT (Cacioppo & Cacioppo, 2018 ) can further explain the mechanisms.…”

Impact of transient and chronic loneliness on progression and reversion of frailty in community-dwelling older adults: four-year follow-up

“…A recent study systemtatically reviewed 57 studies from 113 countries or territories and reported a 21% to 24% of prevalence of loneliness in older adults, which was approximately 10 times that in young adults [9]. Increasing evidence indicates that the onset of the COVID-19 pandemic, along with the constainment measures -such as social distancing restrictions; the 'stay at home' order; and the closure of cafes, restaurants, and gyms -have disproportionately affected older adults, increasing the incidence of loneliness [10]. Loneliness is influenced by external circumstances (for example, bereavement and migration) and the human characteristics of the individual such as health status and personality [11].…”
