Hypothesis
Are loneliness and social isolation independently associated with the risk of non-alcoholic fatty liver disease (NAFLD)?
Conclusion
Loneliness and social isolation are associated with an increased risk of NAFLD, independent of other risk factors.
Supporting Evidence
- Loneliness was associated with a 22% increased risk of NAFLD.
- Social isolation was associated with a 13% increased risk of NAFLD.
- 30.4% of the loneliness-NAFLD association was mediated by unhealthy lifestyle factors.
- 33.2% of the loneliness-NAFLD association was mediated by depression.
- Participants with loneliness or social isolation had higher rates of obesity and smoking.
Takeaway
Feeling lonely or isolated can make your liver sick, even if you don't have other health problems.
Methodology
This study analyzed data from 405,073 participants in the UK Biobank, assessing loneliness and social isolation through questionnaires and tracking NAFLD incidence over a median follow-up of 13.6 years.
Potential Biases
The majority of participants were white Europeans, which may limit the generalizability of the findings.
Limitations
The study's observational design limits causal inferences, and loneliness and social isolation were assessed only once at baseline.
Participant Demographics
Mean age was 56.2 years, with 46.5% men; 4.7% reported loneliness and 8.9% reported social isolation.
