OBJECTIVE: The purpose of this study of adults with type 1 diabetes was to analyze patterns of diabetes self-management behaviors and predictors of glycemic control across the adult life span.

RESEARCH DESIGN AND METHODS: This study was a secondary cross-sectional analysis of data from of 7,153 adults enrolled in the Type 1 Diabetes Exchange clinic registry who were divided into four developmental stages (emerging, young, middle-aged, and older adults). Data were collected by questionnaire and medical record review at enrollment. Statistical analyses compared sociodemographic, clinical, and diabetes-related factors across groups. Logistic regressions were conducted for each group to identify factors associated with hemoglobin A1c ≥7%.

RESULTS: The sample was divided according to adult developmental stage: emerging adults, age 18 to <25 years (n = 2,478 [35%]); young adults, age 25 to <45 years (n = 2,274 [32%]); middle-aged adults, age 45 to <65 years (n = 1,868 [26%]; and older adults, age ≥65 years (n = 533 [7%]). Emerging adults had the highest mean hemoglobin A1c level (8.4 ± 1.7% [68 mmol/mol]), whereas older adults had the lowest level (7.3 ± 0.97% [56 mmol/mol]; P < 0.0001). Emerging adults were less likely to use an insulin pump (56%) or a continuous glucose monitor (7%), but were more likely to miss at least one insulin dose per day (3%) and have had an episode of diabetic ketoacidosis in the past year (7%) (all P < 0.0001). Different factors were associated with hemoglobin A1c ≥7% in each age group, but two factors were noted across several groups: the frequency of blood glucose checks and missed insulin doses.

CONCLUSIONS: When discussing diabetes self-management, providers may consider a patient's developmental stage, with its competing demands, such as work and family; psychosocial adjustments; and the potential burden of comorbidities.
