    Changes in Device Uptake and Glycemic Control Among Pregnant Women With Type 1 Diabetes: Data From the T1D Exchange
    (Sage, 2021) Levy, Carol J.; Foster, Nicole C.; DuBose, Stephanie N.; Agarwal, Shivani; Lyons, Sarah K.; Peters, Anne L.; Uwaifo, Gabriel I.; DiMeglio, Linda A.; Sherr, Jennifer L.; Polsky, Sarit; Pediatrics, School of Medicine
    Objectives: To examine changes in device use and glycemic outcomes for pregnant women from the T1D Exchange Clinic Registry between the years 2010-2013 and 2016-2018. Methods: Participant-reported device use and glycemic outcomes were compared for women aged 16-40 years who were pregnant at the time of survey completion, comparing 2010-2013 (cohort 1) and 2016-2018 (cohort 2). Hemoglobin A1c results within 30 days prior to survey completion were obtained from medical records. Results: There were 208 pregnant women out of 5,236 eligible participants completing the questionnaire in cohort 1 and 47 pregnant women out of 2,818 eligible participants completing the questionaire in cohort 2. Continuous glucose monitor (CGM) use while pregnant trended upward among cohort 2 (70% vs 37%, P = .02), while reported continuous subcutaneous insulin infusion (CSII) use while pregnant declined (76% vs 64%, P = .04). HbA1c levels trended downward (6.8% cohort 1 vs 6.5% cohort 2, P = .07). Conclusions: Self-reported CGM use while pregnant increased over the studied intervals whereas CSII use decreased. Additional evaluation of device use and the potential benefits for T1D pregnancies is needed.

    Health-related quality of life in parents and partners of people with type 1 diabetes: Development and validation of type 1 diabetes and life (T1DAL) measures
    (American Psychological Association, 2021) Hilliard, Marisa E.; Minard, Charles G.; Marrero, David G.; de Wit, Maartje; DuBose, Stephanie N.; Verdejo, Alandra; Jaser, Sarah S.; Kruger, Davida; Monzavi, Roshanak; Shah, Viral N.; Wadwa, R. Paul; Weinstock, Ruth S.; Thompson, Debbe; Cao, Viena T.; Anderson, Barbara J.; Medicine, School of Medicine
    Introduction: Despite the significant impact of type 1 diabetes (T1D) on family, few instruments are available to assess health-related quality of life (HRQOL) among family members of people with T1D. This study aimed to develop and evaluate the psychometric properties of new measures of diabetes-specific HRQOL for parents and partners of people with T1D. We report on the multistep development and validation process for the self-report Type 1 Diabetes and Life (T1DAL) measures, with versions for parents of youth age <8, 8-11, 12-17, and 18-25 years, and for partners of people age ≥18 years with T1D. Method: First, we conducted qualitative interviews (total parents/partners n = 38) to develop draft measures and piloted them (total n = 20). Next, we tested the measures' psychometric properties. Participants (total across versions n = 813) at six T1D Exchange Clinic Network sites completed the appropriate T1DAL measure and validated measures of related constructs. We then reduced each T1DAL measure to 20-30 items in length based on psychometric data and participant feedback. Eleven participants reviewed the final measures via cognitive debriefing. Results: The T1DAL measures for parents and partners demonstrated good internal consistency (α = .80-.88) and test-retest reliability (r = .73-.86). Correlations with measures of general quality of life, generic and diabetes-specific HRQOL, and diabetes burden demonstrated construct validity. Factor analyses identified 3-4 subscales/measure. Participants reported being satisfied with the shortened measures, which took 5-10 minutes to complete. Discussion: The new T1DAL measures for parents and partners of people with T1D are reliable, valid, and ready for use in research and clinical settings.

    Incident Diabetes Complications among Women with type 1 diabetes based on Parity
    (Taylor & Francis, 2020) Polsky, Sarit; Foster, Nicole C.; DuBose, Stephanie N.; Agarwal, Shivani; Lyons, Sarah; Peters, Anne L.; Uwaifo, Gabriel I.; DiMeglio, Linda A.; Sherr, Jennifer L.; Levy, Carol J.; Pediatrics, School of Medicine
    Objectives To assess risk factors and incidence of diabetes complications in women with type 1 diabetes (T1D) based on parity. Research design/methods Data were collected from women (16–40 years old) in the T1D Exchange completing pregnancy/childbirth questionnaires during 2011–2013 and 2016–2018. Incidence of risk factors and diabetes complications were compared between women with a first pregnancy at/within 1-year of enrollment (n = 28) and never pregnant women by year 5 (n = 469). Results There was a trend for lower HbA1c (adjusted p = .14) and higher rates of overweight/obesity, triglyceride/HDL > 2, log (triglyercide/HDL), and hypertension among parous women compared with nulliparous women. There were no significant differences in rates of advanced nephropathy, albuminuria or cardiovascular disease. Conclusions Four-5 years after delivery, parous women with T1D tended to have lower HbA1c levels despite higher body mass indices and more frequent adverse lipid profiles and hypertension compared with nulliparous women. Further studies based on these trends are warranted.

    The obesity epidemic in 32,936 youth with type 1 diabetes (T1D) in the German/Austrian DPV and US T1D Exchange (T1DX) registries
    (Elsevier, 2015-09) DuBose, Stephanie N.; Hermann, Julia M.; Tamborlane, William V.; Beck, Roy W.; Dost, Axel; DiMeglio, Linda A.; Schwab, Karl Otfried; Holl, Reinhard W.; Hofer, Sabine E.; Maahs, David M.; Department of Pediatrics, IU School of Medicine
    Objective To examine the current extent of the obesity problem in 2 large pediatric clinical registries in the US and Europe and to examine the hypotheses that increased body mass index (BMI) z-scores (BMIz) are associated with greater hemoglobin A1c (HbA1c) and increased frequency of severe hypoglycemia in youth with type 1 diabetes (T1D). Study design International (World Health Organization) and national (Centers for Disease Control and Prevention/German Health Interview and Examination Survey for Children and Adolescents) BMI references were used to calculate BMIz in participants (age 2-<18 years and ≥1 year duration of T1D) enrolled in the T1D Exchange (n = 11 435) and the Diabetes Prospective Follow-up (n = 21 501). Associations between BMIz and HbA1c and severe hypoglycemia were assessed. Results Participants in both registries had median BMI values that were greater than international and their respective national reference values. BMIz was significantly greater in the T1D Exchange vs the Diabetes Prospective Follow-up (P < .001). After stratification by age-group, no differences in BMI between registries existed for children 2-5 years, but differences were confirmed for 6- to 9-, 10- to 13-, and 14- to 17-year age groups (all P < .001). Greater BMIz were significantly related to greater HbA1c levels and more frequent occurrence of severe hypoglycemia across the registries, although these associations may not be clinically relevant. Conclusions Excessive weight is a common problem in children with T1D in Germany and Austria and, especially, in the US. Our data suggest that obesity contributes to the challenges in achieving optimal glycemic control in children and adolescents with T1D.
