Glycemic control, depression, diabetes distress among adolescents with type 2 diabetes: effects of sex, race, insurance, and obesity

Abstract

Aims: To determine (1) differences in depression and distress scores between adolescents with type 1 (T1D) and type 2 diabetes (T2D), (2) how socioeconomic factors, obesity, race, and treatment regimen affect depression and diabetes distress in adolescent T2D, (3) the relationships between depression and diabetes distress scores in adolescents with T2D, and (4) how depression and diabetes distress scores relate to current and future glycemic control in adolescents with T2D.

Background: Diabetes distress is a negative emotional reaction to diabetes complications, self-management demands, unresponsive providers, poor interpersonal relationships, and to diabetes itself. It is frequently mistaken for depression and the two are interrelated. Increases in both predict poor glycemic control in adolescents with T1D.

Method: Depression (PHQ-9) and diabetes distress (PAID-T) scores from self-administered tests were studied in 364 patients with diabetes between the ages of 13-17. Kruskal-Wallis test was used to assess differences between types of diabetes, sexes, races, and insurance status. Spearman correlations, and robust rank order multivariable regression analysis were used to assess relationships. Medical records were reviewed for follow-up hemoglobin A1c (HbA1c) levels over 3 years.

Results: HbA1c was significantly lower in females with T2D than with T1D (p = 0.019) but not in males. It, also, did not differ between females and males with T2D. Median PHQ-9 score in females with T2D was significantly greater than in females with T1D (p = 0.007) but did not differ between females and males with T2D. PHQ-9 scores did not differ between males with T2D and T1D. PAID-T scores, however, were higher in males with T2D than in males with T1D but did not differ between females. PHQ-9 scores and PAID-T scores were significantly related in T2D (r_s = 0.65, p < 0.001). Neither was related to HbA1c in T2D.

Conclusions: As in adolescents with T1D, depression and diabetes distress screening scores are closely related in adolescent T2D. However, unlike T1D, they are not related to glycemic control in T2D. Depression and diabetes distress may be more closely related to weight and lifestyle concerns.
