Mental health visits and low socio-economic status in adolescence are associated with complications of Type 1 diabetes in early adulthood: a population-based cohort study.

AIM

To determine the association of mental health visits and socio-economic status in late adolescence with the risk of mortality and acute and chronic diabetes complications in early adulthood.

METHODS

We conducted a population-based cohort study of individuals in Ontario, Canada, who had their 20th birthday between January 1999 and March 2015 and a diagnosis of diabetes prior to their 15 birthday, using linked administrative databases (n=8491). The main outcome was death; other outcomes were hypoglycaemia or hyperglycaemia-related hospitalizations and emergency department visits and chronic diabetes complications (dialysis, ophthalmological and macrovascular complications).

RESULTS

Over the course of 59 361 person-years there were 127 deaths.. Low socio-economic status and mental health visits were both associated with a higher risk of death [hazard ratio 2.03, (95% CI 1.13 to 3.64) and 2.45 (95% CI 1.71 to 3.51), respectively]. Those with the lowest socio-economic status and a mental health visit had a higher rate of diabetes-related hospitalizations (rate ratio 4.84, 95% CI 3.64 to 6.44) and emergency department visits (rate ratio 3.15, 95% CI 1.79 to 5.54). Low socio-economic status and mental health visits were both associated with an increased risk of any chronic complication [hazard ratio 1.54 (95% CI 1.21 to 1.96) and 1.57 (95% CI 1.35 to 1.81), respectively].

CONCLUSION

We identified significant socio-economic and mental health disparities in the risk of death and acute and chronic complications in early adulthood for people with childhood-onset diabetes. Targeted interventions to prevent adverse events for these adolescents at highest risk should be evaluated.
