Five-year changes in loneliness and mental health among adults 41-85 years: the Doetinchem Cohort Study.
Article in Journal of epidemiology and community health, 2025. 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
backgroundBoth loneliness and mental health represent important public health themes with stable or even worsening population figures. The association between loneliness and mental health is cross-sectionally well-established, but longitudinal studies are scarce. The aim of this study is to explore the individual changes in loneliness and mental health and the relation between these changes.
methodsWe used data from wave 5 (years: 2007-2012, n: 4016) and wave 6 (years: 2013-2017, n: 3437) of the Doetinchem Cohort Study, consisting of participants aged 41-86 years. Loneliness was measured using the De Jong-Gierveld 6-item Loneliness Scale and mental health was measured with the 5-item Mental Health Inventory. We assessed changes in loneliness and mental health over a 5-year period. Generalised estimating equations and linear regression were performed to determine the longitudinal association. Associations were adjusted for various sociodemographic, lifestyle and health factors.
resultsOver a 5-year period, 23.4% experienced a change in loneliness and 9.7% in mental health.Higher levels of loneliness were significantly associated with poor mental health both cross-sectionally and over time (β:-3.56, 95% CI: -3.79 to -3.32). Increasing feelings of loneliness were associated with worsening mental health, and decreasing feelings of loneliness were associated with improving mental health (β:-2.35, 95% CI: -2.61 to -2.08).
conclusionThe high rate of individual changes in loneliness, combined with the association between changes in loneliness and changes in mental health, shows a possible potential in improving poor mental health by designing public health interventions aimed at reducing feelings of loneliness.
