Hypothesis
The study aimed to investigate the cumulative incidence of addictions in psoriasis patients and controls in the Stockholm Psoriasis Cohort.
Conclusion
Psoriasis patients showed a tendency towards a higher risk of addiction, particularly alcohol dependency, compared to controls.
Supporting Evidence
- Psoriasis patients had 1.4 times higher odds of addiction diagnosis than controls.
- Alcohol dependency was the most common addiction diagnosis among psoriasis patients.
- Patients were 4.3 times more likely to develop an addiction after their psoriasis diagnosis than before.
Takeaway
People with psoriasis might be more likely to have problems with addiction, especially alcohol, than those without psoriasis.
Methodology
The study used data from the Stockholm Psoriasis Cohort, which included psoriasis patients and matched controls, analyzing medical records and addiction diagnoses from 1987 to 2013.
Potential Biases
Potential biases include missing or incomplete data and reliance on physician-made diagnoses.
Limitations
The study may underestimate addiction due to reliance on ICD codes and lacks recent data, which could affect outcomes.
Participant Demographics
The cohort included 4,545 individuals, with 56.4% female and a median age of 40 years.
