Effective management of diabetes can be complicated by other chronic conditions. This analysis of World Health Organization’s survey looked for an association between symptoms of psychosis and the prevalence of diabetes.
Are people with psychotic symptoms more likely to have diabetes?
The researchers interviewed a sample of patients from the WHO World Health Survey to establish whether they experienced any symptoms of psychosis.
The researchers found:
After controlling for different potential confounders, there was a clear increase in the probability of having diabetes as the number of psychotic symptoms increased.
Users of this research should consider:
- The representativeness of the sample. Could responder bias have influenced the results?
- How many people were interviewed.
- Whether the definitions of “diabetes” and “psychotic symptoms” were adequate.
