High anxiety and depressive symptoms in partners of type 1 diabetes persons in a sample of the Brazilian population

BACKGROUND: Type 1 diabetes (T1D) affects psychologically not only the persons with diabetes themselves but affects their family members. Few studies were conducted to investigate mental health in T1D partners. This study aims: (1) to investigate the frequency of depressive and anxiety symptoms in T1D partners and, (2) to investigate the associations among partners’ depressive and anxiety symptoms and their sociodemographic and behavioral characteristics, and (3) to investigate the associations among partners’ depressive and anxiety symptoms and clinical, laboratory and demographic characteristics of their T1D spouses in a Brazilian population. METHODS: In a transversal study 72 T1D partners were interviewed. Partners were invited to take part in the study during their T1D spouses’ routine consultations. Those who consented to take part in the study signed the consent form. This study followed the principles of the Declaration of Helsinki and was approved by the University Ethics in Research Committee. Inclusion criteria were T1D partners age ≥ 18 and T1D diagnosis > 6 months. Exclusion criteria were cognitive impairment, history of major psychiatric disorders, and severe chronic and terminal diseases. Depressive symptoms were evaluated by the depression subscale of the Hospital Anxiety and Depression scale (HADD) and anxiety symptoms were evaluated by the anxiety subscale of the same instrument (HADA). T1D partners were divided into subgroups according to score ≥ 8 and < 8 in both subscales. Demographic and clinical data were obtained from interview. Descriptive analyses were undertaken using means and percentages, as appropriate. Differences between groups were assessed by the Mann–Whitney test for numerical variables, by the Chi Square test or by Fisher’s exact test for categorical variables, as appropriate. All analyses were undertaken using SAS version 9.2 for Windows. Statistical significance was set at 0.05. RESULTS: Of all 72 T1D partners, 72.2% were male, mean age was 42.7 ± 14.1 years old, years of school attendance were 11.8 ± 3.9 years, and 48.5% had income reaching until 3 Brazilian minimal wages. Forty-three percent reported high anxiety symptoms (HADA ≥ 8) and 18.1% reported high depressive symptoms (HADD ≥ 8). Comparing T1D partners group with HADA ≥ 8 and < 8, the first one was associated with CGM use (41.94% vs 19.51%; p = 0.03). Similarly, comparing T1D partners group with HADD ≥ 8 and < 8, the first one was associated with (1) longer duration of T1D of their spouses (28.6 ± 7.1 vs 22.4 ± 12.2; p = 0.02); (2) less years of school attendance of T1D partners (9.3 ± 3.2 vs 12.3 ± 3.8; p = 0.02), and (3) higher number of hypoglycemic episodes requiring other person’s intervention (6.3 ± 8.9 vs 2.4 ± 4.7; p = 0.009). Seventy-six percent of partners who helped personally in their spouses’ hypoglycemia recovery had HADD ≥ 8 vs 44.7% with HADD < 8 (p = 0.03). Likewise, 84.6% vs 54.2% of partners in which their spouses have T1D chronic complications had HADD ≥ 8 and < 8, respectively (p = 0.04). CONCLUSION: This study showed a high frequency of relevant anxiety and depressive symptoms in this T1D partner population. Several issues related to T1D of their spouses were associated with these symptoms. These results emphasize the need to incorporate the psychological and psychiatric aspects into T1D partners’ education and care.
