- Loneliness is associated with a 32% increased risk of cardiovascular disease events (Holt-Lunstad et al., 2015 meta-analysis)
- A study of young adults found loneliness symptoms associated with higher depressive symptom scores; each 1-point increase in loneliness scale corresponded to an increase in depressive symptoms (Weiss & colleagues, 2018)
- In the UK, 32% of young adults reported they cope with loneliness by increasing online interactions rather than meeting people in person (2020 survey)

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
