Long-term development of loneliness in older people and associations with stringency of COVID-19 measures: an observational cohort study.
Observational study in Age and ageing, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMost longitudinal studies found heightened feelings of loneliness in older people in spring 2020 compared to times before the pandemic. However, longer-term effects are more disputed. We, therefore, investigated changes in loneliness in older people throughout the first 21 months of the COVID-19 pandemic in Switzerland and examined the association between the stringency of COVID-19 measures and feelings of loneliness.
methodsWe assessed loneliness (3-item University of California Los Angeles (UCLA) loneliness scale) in a nationally representative longitudinal observational online survey. Older people (65-79 years) were surveyed between March 2020 and December 2021. Proportions of people feeling lonely (UCLA loneliness scale >6) were compared in two stringent phases ('lockdown', Oxford University stringency index ≥55) and two less restricted phases. Additionally, we explored the situation of potentially more susceptible subgroups (living alone, women, chronic and mental diseases, low educational level and low income).
resultsPhases with stringent measures were associated with higher levels of loneliness in older people. People living alone, women, people with noncommunicable or mental disease diagnoses and lower income show consistently higher levels of loneliness. However, the differences are not accentuated in phases with more stringent measures. We found little differences between subgroups with varying educational levels.
conclusionsEven in a country with relatively less stringent COVID-19 measures like Switzerland, an increase in the proportion of older people that feel lonely could be found during phases with more stringent COVID-19 measures. Lockdown phases should, therefore, be accompanied by evidence-based interventions to relieve loneliness to avoid adverse short- and long-term consequences.
