Social media addiction, maternal mental health, and children's oral health behaviours among immigrants.
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
objectivesOral health disparities persist among immigrants. Little is known about how social media shapes the socio-psychological environment in which parenting and health behaviours occur. This study examined the link between immigrant mothers' anxiety and depression and children's oral health behaviours (OHBs) and evaluated social media addiction as a mediator or moderator.
methodsThis cross-sectional study recruited immigrant parents of children aged 2-12 years in Edmonton, Canada. Parents completed a questionnaire assessing demographics, children's OHBs (dental visits, toothbrushing, diet), anxiety and depression (The Hospital Anxiety and Depression Scale, HADS-14; scored 0-21), and social media addiction (Bergen-6; scored 6-30). Logistic regression, mediation, and moderation analyses were performed.
results302 questionnaires were analyzed. Mean (SD) ages of mothers and children were 37.7 (6.8) and 6.7 (3.3) years, respectively; 49% of children were female, and 65% born in Canada. On average, parents had lived in Canada for 9.9 years, and 68% had higher education. Higher maternal anxiety reduced the odds of child toothbrushing by 14% (OR: 0.86, 95% CI: 0.74 0.98), and higher depression was associated with a 21% reduction (OR: 0.79, 95% CI: 0.63-0.93). Each one-unit increase in anxiety and depression corresponded to a 49% and 51% increase in social media addiction scores (p < .05). No mediation or moderation effects were found.
conclusionsMaternal anxiety and depression reduced children's toothbrushing, with no mediation by social media addiction. Integrating mental health screening into dental care can improve oral health in immigrant communities, fostering better outcomes and inclusive policies.
