Relationships between pre-pandemic mental health, sociodemographic factors and health behaviours in older adults during the acute onset of COVID-19 in Australia: A descriptive analysis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo gain a comprehensive understanding of associations between mental health symptoms and sociodemographic and health factors assessed during COVID-19 restrictions in existing, longitudinal community-based cohorts.
methodsParticipants of The North West Adelaide Health Study (NWAHS, n = 982) and the Florey Adelaide Male Ageing Study (FAMAS, n = 338) in South Australia, undertook a COVID-19 impacts survey during October 2020-May 2021. The Centre for Epidemiologic Studies Depression Scale (score≥16;NWAHS) and the Beck Depression Inventory 1A (score≥13;FAMAS) were used to characterise mild-severe depressive symptoms. The Generalised Anxiety Disorder questionnaire was used to identify moderate-severe anxiety (score 10-21).
resultsOf 1,320 participants (male n = 797), 62.4% (n = 824) were aged ≥65years (range 36-100 years), and 37.8% reported workforce participation at the time of the COVID-19 survey. Depressive and anxiety symptoms were observed for participants aged 35-54years (OR=1.92,95%CI = 1.01-3.67), financial stress (1.81,1.02-3.21), change in overall food intake (increase and decrease), social support none/sometimes(2.74,1.48-5.07), low control/mastery since COVID-19 (6.00,3.37-10.6) and poor sleep during restrictions (7.94,4.25-14.8), independent of previous depressive symptoms (8.30,1.9-13.2). Change in mental health status from pre-COVID to COVID-19 restriction was associated with sex (p = 0.013) and age (p < 0.001), such that females and younger participants (35-54yr) reported depressive symptoms at both times. Younger adults (35-54 yr) showed a higher prevalence of depressive symptoms only during COVID-19.
conclusionsDepressive and anxiety symptoms were consistent during COVID-19 relative to pre-COVID-19. Those with a history of depression, were more likely to report depressive and anxiety symptoms during COVID-19. Government-funded initiatives employed during future pandemics should consider tailored mental health and social support for vulnerable groups.
