Comorbid Chronic Physical Illnesses in Type 1 Diabetes Adolescents: Personal, Caregiver, and Family Functioning.

Having diabetes and comorbid chronic physical illnesses (CCPIs) suggests a higher risk for depression and lower health-related quality of life and treatment adherence. Caring for these patients is often overwhelming. Although CCPIs affect youths with type 1 diabetes (T1D), no study has examined the psychosocial or health-related impact of CCPIs in this population. We examined individual, caregiver, and family functioning differences among T1D adolescents with (G1; n = 25) and without (G2; n = 26) CCPIs. Participants were 51 youth (aged 12-17 years) enrolled in a depression treatment study. We administered diagnostic interviews and rating scales to assess each domain of interest. Using MANOVA, followed by individual univariate analyses, and Chi-square tests, we compared groups in continuous and categorical variables, respectively. MANOVA results were significant, F(4, 46) = 2.62, p = .047. Participants from G1 obtained lower global functioning scores compared to G2. Caregivers whose offspring had CCPIs were more depressed and reported higher burden but lower family functioning scores than their counterparts did. A higher percent of youths with CCPIs needed reminders about insulin use and met the criteria for major depression, but a lower proportion had access to insulin pumps. Taking care of youths from G1 was associated with a lifetime history of depressive disorder or suicidality. Our findings support the existence of individual, caregiver, and family functioning differences between T1D adolescents with vs. without CCPIs. Psychosocial interventions should consider the incremental burden that CCPIs may pose over these youth and their families.
