Description:Objective
To examine the longitudinal associations between sex, diabetes self-care and the health-related quality of life (HRQL) of children and adolescents with Type 1 or Type 2 diabetes.
Study design
The sample included 910 Type 1 and 241 Type 2 participants, ages 10–22 at baseline, from SEARCH for Diabetes in Youth, a longitudinal observational study. The primary outcome measure was the Pediatric Quality of Life Inventory (PedsQL). Repeated measures, mixed model regression analysis was conducted using data from baseline and at least one follow-up assessment, spanning approximately 4 years.
Results
HRQL was higher among those with Type 1 versus Type 2 diabetes. Among Type 1 participants, higher (better) PedsQL total scores over time were related to higher parent education (p=0.0007), lower HbA1c values (p<.0001), and greater physical activity during the past 7 days (p=0.0001). There was a significant interaction between sex and age (p<0.0001); girls’ HRQL remained stable or decreased over time, whereas males’ HRQL increased. For participants with Type 2 diabetes, there was no significant interaction by age and sex, but lower total HRQL was related to being female (p=0.011) and higher BMI-z scores (p=0.014).
Conclusions
HRQL in this cohort varied by diabetes type. The interaction between sex and age for Type 1 participants, coupled with poorer HRQL among females than males with Type 2 diabetes, suggests the impacts of diabetes on HRQL differ by sex and should be considered in clinical management. Encouraging physical activity and weight control continue to be important in improving HRQL.
