Objective Physical distancing and stay-at-home measures implemented to slow transmission of novel coronavirus disease (COVID-19) may intensify feelings of loneliness in older adults, especially those living alone. Our aim was to characterise the extent of loneliness during the first wave in a sample of older adults living in the community and assess characteristics associated with loneliness.

Design Online cross-sectional survey between 6 May and 19 May 2020.

Setting Ontario, Canada.

Participants Convenience sample of members of a national retired educators’ organisation.

Primary outcome measures Self-reported loneliness, including differences between women and men.

Results 4879 respondents (71.0% women; 67.4% 65–79 years) reported that in the preceding week, 43.1% felt lonely at least some of the time, including 8.3% who felt lonely always or often. Women had increased odds of loneliness compared with men, whether living alone (adjusted OR (aOR) 1.52, 95% CI 1.13 to 2.04) or with others (2.44, 95% CI 2.04 to 2.92). Increasing age group decreased the odds of loneliness (aOR 0.69 (95% CI 0.59 to 0.81) 65–79 years and 0.50 (95% CI 0.39 to 0.65) 80+ years compared with <65 years). Living alone was associated with loneliness, with a greater association in men (aOR 4.26, 95% CI 3.15 to 5.76) than women (aOR 2.65, 95% CI 2.26 to 3.11). Other factors associated with loneliness included: fair or poor health (aOR 1.93, 95% CI 1.54 to 2.41), being a caregiver (aOR 1.18, 95% CI 1.02 to 1.37), receiving care (aOR 1.47, 95% CI 1.19 to 1.81), high concern for the pandemic (aOR 1.55, 95% CI 1.31 to 1.84), not experiencing positive effects of pandemic distancing measures (aOR 1.94, 95% CI 1.62 to 2.32) and changes to daily routine (aOR 2.81, 95% CI 1.96 to 4.03).

Conclusions While many older adults reported feeling lonely during COVID-19, several characteristics—such as being female and living alone—increased the odds of loneliness. These characteristics may help identify priorities for targeting interventions to reduce loneliness.

Strengths and limitations of this study

  • The study leveraged a strong community-based partnership to obtain timely data from a large sample of older Canadians on the impacts of the first wave of COVID-19.

  • The study evaluated the association between sociodemographic characteristics, social support, and COVID-19-related attitudes and behaviours, and loneliness, stratified by sex and overall. The data were based on a convenience sample of retired educational staff, who are not fully representative of the Canadian population.

  • The perspectives of vulnerable groups who may be at greater risk for loneliness (eg, those with severe mental health illness, low income, no home internet access, and so on) are likely under-represented in this sample.


As data emerge on how common, yet harmful, it is to be lonely, loneliness is increasingly recognised as a public health priority. In the USA, more than 40% of respondents to the nationally representative Health and Retirement Study reported feeling lonely.1 In Canada, one in four older women and one in five older men report feeling lonely at least some of the time.2 While feelings of loneliness can occur at any age, research has shown that rates of loneliness follow a non-linear U-shaped distribution, with the highest levels reported in young (<25 years) and older (>65 years) adults.3 While predisposing factors differ by life stage, older adults are at increased risk because they are more likely to experience events such as retirement, chronic illness, widowhood and living alone.4 Women report higher rates of loneliness than men,2 4 possibly due to their longer life expectancy and greater likelihood of outliving their spouse, resulting in prolonged widowhood,5 6 their caregiver roles,2 7 8 lower incomes9 and their greater tendency to acknowledge feeling lonely.6 Addressing loneliness is important because of its profound impact on health and well-being, including increased risk for premature death,10 11 cardiovascular disease, depression, dementia and even suicide.12–18

The novel coronavirus pandemic (COVID-19) and accompanying physical distancing and stay-at-home measures (ie, closure of non-essential businesses and public spaces, as well as recommendations to practise physical distancing with anyone outside the home) are expected to intensify feelings of loneliness. Previous infectious disease outbreaks and pandemics have demonstrated increases in loneliness, anxiety and depression from quarantine-induced social isolation.19 20 Emerging research from the early stages of the COVID-19 pandemic support this hypothesis,21 with several studies demonstrating elevated rates of loneliness,22–24 psychological distress,25 26 and anxiety, depression and stress27 28 during lockdown periods.

Understanding how older adults have been impacted by COVID-19 is vital to address their needs promptly and effectively and prevent unnecessary harms as the pandemic persists. Cross-sectional studies published as early as April 2020 examined public concerns regarding COVID-19 (eg, becoming infected, reduced healthcare access) and its impact on daily life.29 30 While valuable, these studies were conducted prior to or on the cusp of the implementation of physical distancing and stay-at-home measures, did not report on mental health, under-represented older adults,29 a key high-risk group and did not explore important differences between women and men. More recently, McGinty et al published prevalence estimates of psychological distress and loneliness in the USA; although subgroup analyses focused on psychological distress rather than loneliness.25

More data on loneliness in older adults during COVID-19 continue to emerge as the pandemic unfolds,24 31–34 yet important knowledge gaps remain. A key gap is whether older women and men have shared, or unique, risk factors for loneliness during the pandemic. Before COVID-19, it has been shown that while there are common contributors to loneliness in older adults, like widowhood or declining health, some risk factors affect the sexes differently. For example, mobility problems have been shown to be a strong predictor of loneliness in women, while a reduced social network strongly predicts loneliness in men.35 There are also comparatively little data on the relationship between COVID-19-specific factors (eg, level of concern, impact to daily life, COVID-19 infection, and so on)22 24 32 and behaviours (eg, use of technology for social connection) with loneliness in general, but particularly in older adults. Timely data relevant to older women and men are needed to inform public health responses and healthcare delivery.

We conducted an online cross-sectional survey to assess how the first wave of the COVID-19 pandemic affected older adults living in the community in Canada. Our objective was to characterise the extent of loneliness in older adults, including differences between women and men, and examine factors associated with loneliness to identify groups likely to benefit most from intervention. We hypothesised that loneliness would be common, particularly in women and those living alone, and that higher pandemic concern would increase loneliness.


Study design and setting

A closed, online cross-sectional survey was administered to members of the RTOERO (formerly known as the Retired Teachers of Ontario) between 6 May and 19 May 2020. At this time in Ontario, Canada, physical distancing measures (eg, lockdown) had been in place for about 7 weeks; daily case and death counts were in decline after peaks in late April; and outbreaks in long-term care homes were a focus of news headlines (figure 1 for timeline).

Figure 1

Timeline of COVID-19 in Ontario, Canada’s largest province. Physical distancing measures beginning 17 March included closure of all indoor recreational facilities, public libraries, theatres, cinemas, bars and restaurants. Publicly funded schools were closed by this point as well, and all employers in Ontario were asked to facilitate virtual work arrangements for employees. Remaining non-essential businesses were closed on 25 March. Gatherings of more than five people were prohibited on 28 March. On 30 March, Ontario’s Chief Medical Officer of Health strongly recommended individuals over 70 years of age or those with compromised immune systems or underlying medical conditions to stay at home.

RTOERO is a voluntary membership organisation of more than 81 000 retired educators, administrators and educational support staff from child care, K-12 and postsecondary settings that provides group health insurance benefits, as well as other programmes and services, to the broader education community ( Members were invited to participate by email from RTOERO’s chief executive officer. Two reminder emails were sent at 7 and 10 days. The survey was not publicly advertised. All members were eligible to participate if they had a registered email address (~62 000). Study materials were provided in English and French. Our study design and reporting followed the Checklist for Reporting Results of Internet E-Surveys.36

A link to a study information sheet was provided on the survey’s home page and informed consent was obtained electronically. Participation was voluntary, and no incentives were provided. Minimal identifying personal information was collected (eg, first three digits of postal code).


The questionnaire was developed with RTOERO leadership and included 32 questions (online supplemental appendix). Several questions were adapted with permission from the Stanford Coronavirus Survey ( Questions examined the impact of COVID-19 on daily life; loneliness; and the use of digital technologies for social connectivity. We used a single-item, direct measure of loneliness by asking respondents, ‘In the past seven days, which statement best applies?’ (I did not feel lonely; I felt lonely 1 or 2 days; I felt lonely several days; I felt lonely most days; I felt lonely every day). This approach was adapted from the Canadian Longitudinal Study on Aging (CLSA)2 and the UK’s Community Life Survey37 which measure loneliness by directly asking, ‘How often do you feel lonely?’ (often/always, some of the time, occasionally, hardly ever or never). We chose this approach because it allowed respondents to self-report on loneliness, anchored their response to a time during the pandemic stay-at-home measures and was considered more suitable for the pandemic context, where asking indirectly about feeling ‘left out’ to infer loneliness may be less relevant as distancing and stay-at-home measures were universally applied.

Respondents were also asked about their history of COVID-19 symptoms and testing, the extent to which they were practising physical distancing and stay-at-home measures, and sociodemographic characteristics (ie, age, sex, ethnicity, language, health status and location of residence). The ethnic response categories we used mirrored those used in Canada’s National Health Survey.38 The questionnaire was pretested in English with 18 RTOERO board members and staff, and in French by one staff member, for usability, technical functionality, clarity, flow, sensitive questions and timing. Pretest results were not included in the final analysis.

Patient and public involvement

As noted above, RTOERO leadership (which comprises members of RTOERO) was involved in all aspects of the study, including questionnaire development, pretesting and participant recruitment. Preliminary results were shared with the team and feedback was incorporated into the final analysis and manuscript. RTOERO’s chief executive officer is a coauthor (JG) and critically reviewed the manuscript. Results were shared with RTOERO members through a webinar in the fall of 2020.

Data collection

The questionnaire was administered using SimpleSurvey. Data were stored in an encrypted, password-protected form on the secure SimpleSurvey server and were downloaded to the secure, password-protected Women’s College Hospital server accessible to authorised team members. All questions were optional, so completeness checks were not performed; although respondents were reminded of unanswered questions before proceeding to the next section to minimise incomplete data. We used adaptive questioning to reduce the complexity of questions.36 39 Respondents were able to save their responses and return to the survey later to complete it. The survey completion rate was the number of respondents who finished the survey divided by the number consenting to participate.36 Surveys were only analysed if the respondent clicked ‘Submit’ and responded to more than one question.


Sociodemographic characteristics—sex, age, living alone, ethnicity, rural residence, health status and caregiver status—were collected based on factors previously reported to be associated with loneliness.4 5 We additionally collected self-reported measures of social support—communication frequency, receiving offers of assistance and social media use—as well as attitudes and behaviours towards COVID-19 hypothesised to contribute to loneliness, including level of concern, change in daily routine, extent of physical distancing and perceived positive effects of distancing measures. Variable definitions are presented in the online supplemental eMethods.


Our primary outcome was loneliness. Respondents were categorised as lonely ‘always or often’ if they reported feeling lonely every or most days in the preceding 7 days; lonely ‘some of the time’ if they reported feeling lonely on 1–2 or several days; and ‘not lonely’ if they reported they had not felt lonely at all. We further collapsed the first two categories to create a dichotomous variable for loneliness, where respondents were classified as lonely if they reported feeling lonely on 1 or more days in the preceding 7 days.2 37


Χ2 tests were used to identify sex differences. To identify predictors of loneliness for older women and men, exploratory analyses using sex-stratified and sex-pooled multivariable logistic regression models were conducted. In the sex-stratified regression analysis, we calculated unadjusted and minimally adjusted (age and health status) models, and used findings to inform which interactions to test for in the sex-pooled analysis. In the sex-pooled model, we additionally adjusted for all covariates and formally tested for sex interactions with explanatory factors, including age group, living alone, communication frequency, receiving offers of assistance, change in daily routine and perceived positive effects of distancing measures, using interaction terms. Statistical tests were two sided, with p<0.05 interpreted as statistically significant. Analyses were performed using SAS V.9.4.


Overall, 5556 RTOERO members responded to the survey, of which 5509 provided consent. A total of 4891 surveys were submitted for a completion rate of 88.8%. We excluded 12 respondents who responded to ≤1 survey question, leaving 4879 respondents included in the analysis.


Most respondents were women (3421/4818 (71.0%)), between the ages of 65 and 79 years (3279/4863 (67.4%)) and completed the survey in English (97.6%) (table 1). They were similar to the broader RTOERO membership in terms of sex (67% female), age distribution (14.5% <65 years; 64% 65–79 years; 21.5% ≥80 years) and preferred language (95% English) (J Grieve, personal communication). One-third of female respondents lived alone (1138/3356 (33.9%)) compared with one-fifth of men (266/1351 (19.7%)). Respondents were predominantly white (4454/4861 (91.6%)) and in good self-reported health (4370/4873 (89.7%)).

Table 1

Sociodemographic characteristics of older female and male survey respondents

Less than 5% (236/4790 (4.9%)) reported a cold or influenza-like illness in the preceding month. Overall, 8 of 4861 respondents tested positive for COVID-19 (0.2%). Most respondents strongly agreed that the COVID-19 pandemic had changed their daily routine (67.5% females vs 63.2% males, p=0.0047). Additional data on the impact of COVID-19 are reported in online supplemental table 1 and figure 1.

Loneliness during COVID-19

Overall, 43.1% of respondents felt lonely at least some of the time (34.8% some of the time and 8.3% always or often) (table 2). Women were more likely to report feeling lonely than males (p<0.001). Strategies to avoid feeling lonely included connecting with a friend or family member (82.1% women vs 70.7% men, p<0.001) and getting fresh air (65.3% vs 61.9%, p=0.025). Seven per cent (7.1%) described other strategies, such as reading, housework and/or gardening and practising their faith. Most participants frequently spoke with a friend, family member or neighbour, although a small proportion (0.4%) had no connection at all. Many used social networking websites or apps (87.3% females vs 78.2% males, p<0.001).

Table 2

Sex-stratified model

Most factors associated with loneliness were shared among women and men (table 3). Older age significantly reduced the odds of loneliness in both sexes after adjustment for self-reported health status. Living alone was associated with loneliness in both women and men; although the association was greater in men (adjusted OR (aOR) 3.86 (95% CI 2.88 to 5.18) vs aOR 2.50 (95% CI 2.14 to 2.92)). Self-reported poor health and higher concern for the pandemic were also associated with loneliness, as were experiencing change to a daily routine, and not experiencing any positive effects or ‘silver linings’ of pandemic distancing measures; effect sizes varied by sex. Among women, receiving offers of assistance (aOR 0.79, 95% CI 0.69 to 0.91) and communicating more often with a friend, family member or neighbour (aOR 0.47, 95% CI 0.34 to 0.66) reduced the odds of loneliness.

Sex-pooled model

Women had increased odds of loneliness compared with men, irrespective of living arrangement (aOR 1.52 (95% CI 1.13 to 2.04) living alone; aOR 2.44 (95% CI 2.04 to 2.92) living with others) (table 4). Increasing age group was associated with decreasing odds of loneliness. The association of living alone with loneliness was significantly greater for men than women (aOR 4.26 (95% CI 3.15 to 5.76) vs 2.65 (95% CI 2.26 to 3.11), p=0.006 for interaction term). Additional characteristics associated with loneliness included: self-reported fair/poor health (aOR 1.93, 95% CI 1.54 to 2.41), being a caregiver (aOR 1.18, 95% CI 1.02 to 1.37) and receiving care from a caregiver (aOR 1.47, 95% CI 1.19 to 1.81). Pandemic-related factors associated with an increased odds of loneliness included having a high concern for the pandemic (aOR 1.55, 95% CI 1.31 to 1.84), not experiencing any positive effects or ‘silver linings’ of pandemic distancing measures (aOR 1.94, 95% CI 1.62 to 2.32) and experiencing change to a daily routine (aOR 2.81, 95% CI 1.96 to 4.03). Non-white ethnicity (aOR 0.71, 95% CI 0.54 to 0.94), high frequency of communication (aOR 0.55, 95% CI 0.43 to 0.72) and receiving offers of assistance (aOR 0.79, 95% CI 0.69 to 0.90) reduced the odds of loneliness. None of the other sex-based interactions we explored with explanatory factors were significant. Social media use was not associated with loneliness (aOR 1.13, 95% CI 0.94 to 1.36) and the addition of an interaction term between social media use and age was similarly not significant.

In a survey of 4879 older women and men, we found that loneliness was common during the COVID-19 pandemic, with more than one-third (34.8%) of respondents reporting feeling lonely some of the time and 8.3% feeling lonely always or often. More women reported feeling lonely than men and had higher odds of loneliness, despite controlling for factors hypothesised to contribute to sex differences including living alone, health status and caregiving. Our findings are similar to reports from the UK, where 22.4% and 4.1% of older adults reported feeling lonely sometimes or often, respectively, in the first 4 weeks of lockdown,32 and from the USA, where 13.8% (95% CI 11.4% to 16.6%) of adults aged ≥18 years reported feeling lonely always or often at the beginning of April 2020.25

Living alone is as an important risk factor for loneliness, both pre-COVID-195 40 41 and during the pandemic.31–33 We found that living alone predicted loneliness in women and men, although the effect was greater in men. Physical distancing and stay-at-home measures are anticipated to have a greater toll for those living alone as they severely limit opportunities for face-to-face interaction to combat loneliness.33 The effect of living alone on loneliness may be greater in men because they tend to have fewer social contacts and close friends than women.35 42 43 Indeed, male respondents in our survey communicated less frequently with family, friends and neighbours, and were less likely to seek out social connection to mitigate loneliness. Having a smaller social network may exacerbate some of the negative effects of living alone. Emerson recently found that older US adults who lived alone were less likely to have a close relationship that provided emotional security and well-being, and more likely to become ‘more lonely’ following the onset of COVID-19 than those living with others (42.4% vs 27.9%).31 Alternatively, our finding may be due to the inherent overlap in the constructs of ‘living alone’ and ‘marital status’ because we partially captured the impact of being widowed or unmarried in men versus women. Prior research has shown that being single has a greater impact on men’s loneliness, possibly explained by the fact that for many older men, their partners are their main confidante and source of intimacy.44 45

We found that older adults’ perceptions and pandemic experiences were also associated with loneliness. Respondents who had a high level of concern for COVID-19, experienced changes to their daily routine and reported no perceived positive effects or ‘silver livings’ from the pandemic had increased odds of loneliness, while receiving offers of support and frequently communicating with family, friends and neighbours were protective. These findings underscore the importance of public health messages from the WHO targeted at older adults, including maintaining regular routines or creating new ones that include exercise, regular cleaning/chores and enjoyable activities; keeping in regular contact with loved ones; and restricting news consumption to specific times of day from reputable sources to reduce undue anxiety or distress.46

Family physician visits have been suggested as an important opportunity to screen for loneliness during COVID-19.47 48 Particular attention is recommended to be paid to patients who are older, live alone or have pre-existing health conditions.47 Our findings suggest that considering the patient’s sex, if they have sufficient social support and how the pandemic is affecting their daily routines could further assist in identifying at-risk individuals. Such questions would also be beneficial to align patients more purposefully with interventions. Virtual consultations and social prescribing (ie, linking patients with non-clinical supports in their community such as outdoor exercise classes, walking groups, virtual bereavement programmes, and so on) may be effective strategies to reduce loneliness during COVID-19 and beyond.47 49 50 Additionally, the Campaign to End Loneliness recently profiled psychological approaches,51 including cognitive–behavioural therapy (CBT),52 53 mindfulness54 and positive psychology,55 as promising interventions for addressing loneliness in older adults.

Lastly, technology can facilitate social connection and improve access to psychological interventions in the midst of physical distancing measures.49 56 For older adults experiencing social loneliness as a result of being disconnected from their social network, websites or apps such as FaceTime and Zoom can connect them to family and friends and provide continuity of group activities such as exercise classes, spiritual services, and so on.57 These platforms can similarly enable access to virtual CBT and other psychological supports.57 One important consideration, however, is that, in order to be effective, older adults must want to, know how to use, and have access to these technologies.57 Recent research shows that many older adults lack access to internet-enabled devices,58 and are unready for comparable technologies (ie, video telemedicine visits) due to inexperience with technology or physical disability.59 Consistent with prior research31 60 and likely a function of electronic survey administration, we found high levels (~85%) of social media engagement, with no increased risk for loneliness overall or by age. Our findings suggest there is a large segment of the older adult population for whom digital media-based interventions may be effective for mitigating and alleviating loneliness. Services that teach older adults how to use and connect with family and friends through social media platforms may be valuable.61 The importance of offline connection, however, should not be forgotten—phoning parents or older neighbours, and extending offers of assistance can go a long way to making someone feel connected and visible.62

A recent US study reported that 30.9% of older adults surveyed felt more lonely after COVID-19-related physical distancing was implemented.31 Our estimates of loneliness were almost double that of the CLSA’s collected between 2010 and 2015 using a similar age group and measurement approach (49.3% of women and 27.1% of men aged 65–79 years felt lonely some of the time vs 24.7% and 17.9%, respectively, for adults aged 65–74 years).2 63 Comparisons should be made cautiously considering differences in study populations. Longitudinal studies provide the most robust evidence of temporal changes. Using data collected at three time points, Luchetti et al found that older adults were the only group studied that showed a slight increase in loneliness in late March 2020 after social distancing measures were implemented in the USA compared with the baseline assessment in January/February, although levels remained stable in April.33 The study found that this increase was driven primarily by unavailable social connections, rather than feelings of isolation. O’Connor et al similarly observed an increase in self-reported loneliness in adults aged ≥60 years at two time points early in the pandemic but not in younger age groups,64 while other studies have reported no change in loneliness over the course of the first pandemic wave.26 65 As we move through successive pandemic waves, it will continue to be important to consistently measure how rates of loneliness change across different age groups to assess the longer term effects of protracted physical distancing and stay-at-home measures. Such longitudinal studies will be vital to characterising trajectories, identifying drivers of change and determining at-risk populations who could benefit from additional support, including young adults, who have reported among the highest levels of loneliness during this pandemic.33 64 65


Our study leveraged a strong community-based partnership to obtain timely data from a large sample of older Canadians on the impacts of COVID-19 during the first wave but had several limitations. Given the cross-sectional study design, causation should not be inferred. Analyses were exploratory and intended to identify characteristics and circumstances associated with loneliness to help target supports to those who could benefit from them. The second limitation is that the data are based on a convenience sample of retired educational staff, who are not fully representative of the Canadian population. The perspectives of vulnerable groups who may be at greater risk for loneliness (eg, those with severe mental health illness, low income, no home internet access, and so on) are likely under-represented in this sample. As such, our findings may be a conservative estimate of loneliness. Finally, the measure of loneliness used in our study has not been validated; although our findings support its criterion validity.


While many older adults reported feeling lonely during the first wave of COVID-19, several characteristics—in particular being female and living alone—increased the odds of loneliness. These characteristics may help guide targeting interventions to reduce loneliness as the pandemic persists.
