Psychosocial Factors and Glycemic Control in Young Adults With Youth-Onset Type 2 Diabetes

Importance

Youth-onset type 2 diabetes is associated with poor glycemic control and early onset of complications. Identification of psychosocial factors associated with poor glycemic control is needed to inform efficacious interventions.

Objective

To identify psychosocial factors associated with glycated hemoglobin (HbA1c) levels in young adults with youth-onset type 2 diabetes.

Design, Setting, and Participants

For the iCount cohort study, HbA1c levels were measured twice (at baseline [T1] and at 1 year [T2]) during the last years (2017-2019) of the observational phase of the multicenter Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY2) study. Participants were young adults who had been diagnosed with type 2 diabetes during childhood or adolescence. Data were analyzed from December 2021 to September 2023.

Main Outcomes and Measures

Glycemic control was examined categorically (high [≥8.0%] vs low [<8.0%] HbA1c), continuously (HbA1c level), and over time (change in HbA1c: decreased ≥0.5%, remained stable, or increased ≥0.5%). Psychosocial measures included beliefs about medicines, depression and anxiety symptoms, diabetes distress, diabetes self-efficacy, self-management support, and unmet material needs. Multivariable logistic and linear regression models evaluated the association of each psychosocial factor with the probability of T2 HbA1c of 8.0% or greater, T2 HbA1c level, and change in HbA1c.

Results

Of the 411 TODAY2 participants approached, 381 enrolled in the iCount study, and 348 with T1 and T2 HbA1c data comprised the analysis group. The 348 participants had a mean (SD) age of 26.1 (2.5) years and a mean (SD) HbA1c of 9.4% (2.8%). Most participants (229 [65.8%]) were women. In adjusted multivariable regressions, greater beliefs that diabetes medicines are necessary (odds ratio [OR], 1.19 [95% CI, 1.03-1.37]; P = .02), concerns about medicines (OR, 1.20 [95% CI, 1.00-1.45]; P = .049), diabetes distress (OR, 1.08 [95% CI, 1.02-1.15]; P = .006), and high distress (OR, 2.18 [95% CI, 1.15-4.13]; P = .02) increased the odds of high HbA1c at T2. Greater support (OR, 0.67 [95% CI, 0.46-0.97]; P = .04) and diabetes self-efficacy (OR, 0.91 [95% CI, 0.84-0.99]; P = .02) decreased the odds of high HbA1c at T2. Diabetes distress was associated with higher HbA1c level at T2 (coefficient, 0.08 [95% CI, 0.02-0.13]; P = .01). Beliefs that diabetes medicines are necessary (OR, 1.20 [95% CI, 1.03-1.39]; P = .02) and concerns about medicines (OR, 1.22 [95% CI, 1.00-1.47]; P = .048) increased the odds of an HbA1c decrease of at least 0.5% over 1 year.

Conclusions and Relevance

In this cohort study of young adults with youth-onset type 2 diabetes, beliefs about medicines, high diabetes distress, low diabetes self-efficacy, and self-management support were associated with high HbA1c over time. Future research should assess whether interventions that address these factors result in improved glycemic control in this at-risk group.

Psychosocial Factors Predicting Healthcare Usage in Young Adults with Youth-Onset Type 2 Diabetes: The TODAY2 iCount Observational Study

BACKGROUND

Established diabetes care ("diabetes home") and regular healthcare visits are important to achieve optimal health. Nothing is known about psychosocial factors that predict healthcare usage (HCU) in young adults with youth-onset type 2 diabetes, at risk for early complications.

OBJECTIVE

To identify psychosocial predictors of HCU in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY2) cohort.

DESIGN

Longitudinal, measured at T1 (baseline) and T2 (1 year later). Logistic and linear regressions, adjusted for potential confounders, identified predictors of sub-optimal HCU (defined as no diabetes home, 0 visits for routine care, or  ≥ 1 urgent care visit in prior 6 months).

PARTICIPANTS

N = 366 TODAY2 participants with T1 and T2 data (381 consented). Mean age = 26.0 years, 67.8% female, 37.7% non-Hispanic Black, 35.8% Hispanic, 20.2% non-Hispanic white, 6.3% "other," mean HbA1c = 9.4%.

MAIN MEASURES

HCU survey; reliable and valid measures of diabetes self-efficacy, depressive symptoms, anxiety symptoms, diabetes distress, beliefs about medicines, diabetes attitudes, material need insecurities, self-management support.

KEY RESULTS

25.4% had no diabetes home, 23.7% had 0 routine care visits, 46% had  ≥ 1 urgent care visit (prior 6 months). Beliefs in the necessity of (adjusted odds ratio [OR] = 1.28; 95% confidence interval [CI] = 1.12, 1.46, p < 0.001), and concerns about (OR = 1.29;CI = 1.08,1.54, p = 0.004), diabetes medicines, and its negative psychosocial impacts (OR = 1.57;CI = 1.04, 2.38, p = 0.03), predicted higher odds of having a diabetes home at T2. Beliefs that medicines are harmful predicted lower odds of a diabetes home (OR = 0.56;CI = 0.37,0.85, p = 0.006). Necessity beliefs (OR = 1.2;CI = 1.06,1.36, p = 0.004), and self-management support (OR = 1.5;CI = 1.08,2.07, p = 0.01) predicted higher odds of having  ≥ 1 diabetes care visit, harm beliefs predicted lower odds (OR = 0.6;CI = 0.41,0.88, p = 0.01).

CONCLUSIONS

Sub-optimal healthcare usage, common in young adults with youth-onset type 2 diabetes, is predicted by beliefs about medicines, diabetes impact, and self-management support. We must address these factors to help this vulnerable group establish stable diabetes care.

Antihypertensive and Lipid-Lowering Medication Adherence in Young Adults With Youth-Onset Type 2 Diabetes

Importance

Youth-onset type 2 diabetes is associated with early development of chronic complications. Treatment of elevated blood pressure (BP), nephropathy, and dyslipidemia are critical to reduce morbidity. Data are needed on adherence to BP- and lipid-lowering medications in young adults with youth-onset diabetes.

Objective

To assess adherence and factors associated with adherence to BP- and lipid-lowering medications in young adults with youth-onset type 2 diabetes and diagnoses of hypertension, nephropathy, or dyslipidemia.

Design, Setting, and Participants

This cohort study measured medication adherence with 3 monthly unannounced pill counts at 2 time points 1 year apart during iCount, conducted during the last years (2017-2019) of the observational phase of the Treatment Options for Type 2 Diabetes in Adolescents and Youth study. Psychosocial factors associated with medication adherence were examined. Participants included individuals with youth-onset type 2 diabetes with hypertension, nephropathy, or dyslipidemia receiving diabetes care in their communities. Data were analyzed from September 2022 to September 2023.

Main Outcomes and Measures

The main outcome was BP- and lipid-lowering medication adherence, with low adherence defined as using less than 80% of pills and high adherence, at least 80% of pills. Psychosocial factors were measured using the Beliefs about Medicines Questionnaire and Material Needs Insecurities Survey.

Results

Of 381 participants in iCount, 243 participants (mean [SD] age, 26.12 [2.51] years; 159 [65.43%] women) with hypertension, nephropathy, or dyslipidemia were included in analysis. Among 196 participants with hypertension or nephropathy, 157 (80.1%) had low adherence. Participants with low adherence, compared with those with high adherence, were younger (mean [SD] age, 25.99 [2.41] vs 27.26 [2.41] years; P = .005), had higher glycated hemoglobin A1c (mean [SD], 10.33% [2.66 percentage points] vs 8.85% [2.39 percentage points]; P = .001), shorter diabetes duration (mean [SD], 12.32 [1.49] vs 12.90 [1.46] years; P = .03), and less education (eg, 17 participants [10.83%] vs 0 participants with no high school diploma; P = .004). Of 146 participants with dyslipidemia, 137 (93.8%) had low adherence and only 9 participants (6.2%) had high adherence. Of 103 participants with low adherence to BP-lowering medications and using oral hypoglycemic agents, 83 (80.58%) had low adherence to oral hypoglycemic agents. Beliefs that medications are necessary were higher for participants with high adherence to BP-lowering medications than those with low adherence in unadjusted analyses (mean [SD] necessity score, 16.87 [6.78] vs 13.89 [9.15]; P = .03). In adjusted multivariable analyses of participants with hypertension or nephropathy, having at least 1 unmet social need (odds ratio [OR], 0.20; 95% CI, 0.05-0.65; P = .04) and medication concerns (OR, 0.63; 95% CI, 0.40-0.96; P = .01) were associated with worse medication adherence 1 year follow-up. Diabetes distress, self-efficacy, depressive and anxiety symptoms, and self-management support were not associated with 1-year medication adherence.

Conclusions and Relevance

These findings suggest that adherence to BP- and lipid-lowering medications was very poor in this cohort. To improve medication adherence and prevent early vascular events, approaches that identify and address medication concerns and unmet social needs are needed.

Twelve-month psychosocial outcomes of continuous glucose monitoring with behavioural support in parents of young children with type 1 diabetes

AIM

Managing type 1 diabetes in young children can cause significant stress for parents. Continuous glucose monitoring (CGM) may reduce parental burden. The Strategies to Enhance CGM Use in Early Childhood (SENCE) trial randomized parents of children (ages 2 to <8 years) with type 1 diabetes to CGM with family behavioural intervention (CGM + FBI), CGM alone (Standard-CGM) or blood glucose monitoring for 26 weeks before receiving CGM + FBI (BGM-Crossover). This report assesses changes in psychosocial outcomes for all groups over 52 weeks.

METHODS

CGM + FBI (n = 45), Standard-CGM (n = 42) and BGM-Crossover (n = 44) participants completed psychosocial assessments at baseline, 26 weeks and 52 weeks. Repeated measures linear regression models evaluated change within and between treatment groups.

RESULTS

The BGM-Crossover group reported improved diabetes burden (Δ -6.9, 95% CI [-11.3, -2.6], p = 0.003), fear of hypoglycaemia (Δ -6.4, CI [-10.1, -2.6], p = 0.002) and technology satisfaction (Δ 7.3, CI [2.4, 12.2], p = 0.005) from 26 to 52 weeks, similar to published findings in the CGM + FBI group over the first 26 weeks. The Standard-CGM group reported increased technology satisfaction (Δ 7.3, CI [0.6, 14.0], p = 0.027) from baseline to 52 weeks. The CGM + FBI group reported less diabetes burden and fear of hypoglycaemia from baseline to 52 weeks, but changes were not statistically significant. Scores from 26 to 52 weeks did not deteriorate.

CONCLUSIONS

Parents demonstrated psychosocial benefits following FBI that appeared to maintain without additional intervention. CGM-focused education with behavioural support likely helps parents of young children with type 1 diabetes reduce burden and worry in the short- and long-term.

Long-term Continuous Glucose Monitor Use in Very Young Children With Type 1 Diabetes: One-Year Results From the SENCE Study

OBJECTIVES

Achieving optimal glycemic outcomes in young children with type 1 diabetes (T1D) is challenging. This study examined the durability of continuous glucose monitoring (CGM) coupled with a family behavioral intervention (FBI) to improve glycemia.

STUDY DESIGN

This one-year study included an initial 26-week randomized controlled trial of CGM with FBI (CGM+FBI) and CGM alone (Standard-CGM) compared with blood glucose monitoring (BGM), followed by a 26-week extension phase wherein the BGM Group received the CGM+FBI (BGM-Crossover) and both original CGM groups continued this technology.

RESULTS

Time in range (70-180 mg/dL) did not improve with CGM use (CGM+FBI: baseline 37%, 52 weeks 41%; Standard-CGM: baseline 41%, 52 weeks 44%; BGM-Crossover: 26 weeks 38%, 52 weeks 40%). All three groups sustained decreases in hypoglycemia (<70 mg/dL) with CGM use (CGM+FBI: baseline 3.4%, 52 weeks 2.0%; Standard-CGM: baseline 4.1%, 52 weeks 2.1%; BGM-Crossover: 26 weeks 4.5%, 52 weeks 1.7%, P-values <.001). Hemoglobin A1c was unchanged with CGM use (CGM+FBI: baseline 8.3%, 52 weeks 8.2%; Standard-CGM: baseline 8.2%, 52 weeks 8.0%; BGM-Crossover: 26 weeks 8.1%, 52 weeks 8.3%). Sensor use remained high (52-week study visit: CGM+FBI 91%, Standard-CGM 92%, BGM-Crossover 88%).

CONCLUSION

Over 12 months young children with T1D using newer CGM technology sustained reductions in hypoglycemia and, in contrast to prior studies, persistently wore CGM. However, pervasive hyperglycemia remained unmitigated. This indicates an urgent need for further advances in diabetes technology, behavioral support, and diabetes management educational approaches to optimize glycemia in young children.

Psychosocial factors predict medication adherence in young adults with youth-onset type 2 diabetes: Longitudinal results from the TODAY2 iCount study

AIM

To identify psychosocial predictors of medication adherence in young adults with youth-onset type 2 diabetes in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY2) cohort.

METHODS

Participants (mean age: 26 years) completed validated psychosocial measures. Unannounced telephone pill counts were completed at T1 (baseline) and T2 (follow-up, approximately 1 year later) to assess adherence to oral hypoglycaemia agents (OHAs). Adherence to insulin was assessed by self-report. Logistic and linear regressions identified factors that predicted 'low adherence' (<80% of pills/insulin) and per cent adherence, adjusted for potential confounders.

RESULTS

Of 171 participants with OHA adherence scores at T1 and T2 (65% women, 43% Hispanic and 35% non-Hispanic Black), 65.4% were low adherent. After adjustment (including T1 adherence), concerns about diabetes medicines (adverse effects, dependence) at T1 predicted higher odds of being low adherent (categorical) at T2 (p = 0.019). Housing insecurity (p = 0.045) and reporting ≥2 need insecurities (p = 0.027) at T1 predicted lower per cent adherence (continuous) at T2. Of 157 participants with insulin adherence scores at T1 and T2 (69% women, 38% Hispanic and 38% non-Hispanic Black), 36.3% were low adherent. After adjustment (including T1 adherence), beliefs that medicines are overused predicted higher odds of insulin low adherence at T2 (p = 0.013), and beliefs that medicines are harmful (p = 0.004) and overused (p = 0.010) predicted lower per cent insulin adherence at T2.

CONCLUSIONS

Suboptimal medication adherence, common in young adults with youth-onset type 2 diabetes, is predicted by interfering beliefs about medicines and social factors. We must address these beliefs and unmet needs to develop tailored interventions for this vulnerable group.

Observed Characteristics Associated with Diabetes Device Use Among Teens with Type 1 Diabetes

BACKGROUND

Despite advancements in diabetes technologies, disparities remain with respect to diabetes device use in youth with type 1 diabetes (T1D). We compared sociodemographic, diabetes, and psychosocial characteristics associated with device (pump and continuous glucose monitor [CGM]) use in 13- to 17-year-old teens with T1D.

MATERIALS/METHODS

Data were derived from a multicenter clinical trial to optimize self-care and glycemic control in teens with T1D. We categorized teens as pump users versus non-users and CGM users versus non-users based on their diabetes device usage. Chi-square and t-tests compared characteristics according to device use.

RESULTS

The sample comprised 301 teens (50% female) with baseline mean ± SD age 15.0 ± 1.3 years, T1D duration 6.5 ± 3.7 years, and HbA1c 8.5 ± 1.1% (69 ± 12 mmol/mol). Two-thirds (65%) were pump users, and 27% were CGM users. Pump users and CGM users (vs. non-users) were more likely to have a family annual household income ≥$150,000, private health insurance, and a parent with a college education (all P < .001). Pump users and CGM users (vs. non-users) also performed more frequent daily blood glucose (BG) checks (both P < .001) and reported more diabetes self-care behaviors (both P < .05). Pump users were less likely to have baseline HbA1c ≥9% (75 mmol/mol) (P = .005) and to report fewer depressive symptoms (P = .02) than pump non-users. Parents of both CGM and pump users reported a higher quality of life in their youth (P < .05).

CONCLUSION

There were many sociodemographic, diabetes-specific, and psychosocial factors associated with device use. Modifiable factors can serve as the target for clinical interventions; youth with non-modifiable factors can receive extra support to overcome potential barriers to device use.

Association of psychosocial factors with medication adherence in emerging adults with youth-onset type 2 diabetes: The iCount study

AIMS

To assess associations of psychosocial factors with medication adherence in young adults with youth-onset type 2 diabetes in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY2) cohort.

METHODS

Participants (mean age 26 years) completed validated psychosocial measures. Adherence to oral hypoglycemia agents (OHAs) was assessed with 3-monthly unannounced phone pill counts; insulin adherence by self-report. Logistic and linear regressions identified factors associated with "low-adherence" (<80% of pills/insulin) controlling for confounders.

RESULTS

Of 212 participants taking OHAs (67% female, 39% Hispanic, 36% non-Hispanic Black), 69.8% were low-adherent. After adjustment, beliefs that medicines are necessary was associated with lower odds of low-adherence (p = 0.040, dichotomous). Less self-management support (p = 0.008), no healthcare coverage (p = 0.001), ≥1 (p = 0.008)/≥2 (p = 0.045) need insecurities were associated with higher odds of low-adherence. Factors associated with lower % adherence (continuous) were beliefs that medicines are harmful (p < 0.001)/overused (p = 0.007)/less necessary (p = 0.022), low self-management support (p = 0.003), food insecurity (p = 0.036), no healthcare coverage (p < 0.001), ≥1 (p = 0.003)/≥2 (p = 0.018) need insecurities. Of 192 taking insulin (69% female, 36% Hispanic, 41% non-Hispanic Black, 16% non-Hispanic white), 37.0% were low-adherent. Beliefs that medicines are overused (p = 0.009), that diabetes is not serious (p = 0.010), low diabetes self-efficacy (p = 0.035), high distress (p = 0.027), low self-management support (p = 0.001), food insecurity (p = 0.020), ≥1 (p = 0.011)/≥2 (p = 0.015) insecurities increased odds of insulin low-adherence.

CONCLUSIONS

Poor medication adherence, common in young adults with youth-onset type 2 diabetes, is associated with interfering beliefs, diabetes distress and social factors. We must address these factors to develop tailored interventions for this vulnerable group.

Risky self-management behaviors in adolescents with type 1 diabetes: Measurement validation for the Diabetes-Specific Risk-Taking Inventory

OBJECTIVE

Among persons with type 1 diabetes (T1D), adolescents often experience the greatest challenge achieving optimal treatment engagement and glycemic targets. Risk-taking behaviors often increase during adolescence and may interfere with engagement in T1D care. We developed the Diabetes-Specific Risk-Taking Inventory (DSRI) to assess risky T1D self-management behaviors in adolescents with T1D. In the current study, we aimed to examine the DSRI's psychometric properties.

RESEARCH DESIGN AND METHODS

We surveyed a national sample of 224 adolescents from the T1D Exchange registry (M age = 16.9 ± 1.1, 49% female, M A1c = 8.5% ± 1.3, 76.8% on insulin pumps) in a cross-sectional design. Participants completed the DSRI and measures of engagement, general risk-taking, and executive functioning and reported on incidence of severe hypoglycemia and diabetic ketoacidosis over the past year.

RESULTS

The DSRI demonstrated reliability (internal consistency: α = 0.89; test-retest reliability: r = 0.86, p < 0.01). Concurrent validity was demonstrated through significant associations between the DSRI and T1D engagement (r = -0.75), general risk-taking (r = 0.57), executive dysfunction (r = 0.34), and report of severe hypoglycemia over the past year (r = 0.22). The DSRI accounted for unique variance in adolescents' most recent glycated hemoglobin, above and beyond other variables, indicating its incremental validity.

CONCLUSIONS

Overall, initial psychometrics suggest the DSRI is a reliable and valid measure of risks that adolescents may take with their T1D care. This innovative self-report measure has potential to be an actionable clinical tool to screen for high-risk behaviors not routinely assessed in T1D clinical care.

Diabetes-Related Worries and Coping Among Youth and Young Adults With Type 1 Diabetes

OBJECTIVE

Although mood and anxiety symptoms are common in youth with type 1 diabetes (T1D), little research has described their worries across developmental stages or the strategies they use to cope with these worries. This secondary data analysis aimed to describe and characterize common T1D-related worries and coping strategies from middle childhood through young adulthood.

METHODS

Twenty-three youth (9 children, 7 adolescents, and 7 young adults) completed semistructured qualitative interviews about health-related quality of life. We coded interview transcripts using thematic analysis to generate common themes of diabetes-related worries and coping strategies.

RESULTS

Participants' worries fell into four major themes: Managing Blood Glucose, Self-Efficacy for Diabetes Management, Interpersonal Relationships, and Lifestyle Impact, and eight youth denied having diabetes-related worries. Coping strategies fell into the three major themes: Attempts to Change Source of Worry, Attempts to Change Reactions to Worry, and Attempts to Orient Away from the Worry.

CONCLUSIONS

Youths' worries about various aspects of living with and feeling able to self-manage diabetes are important to consider across pediatric development as they can impact youths' participation in daily activities and future plans. By adolescence, youth report longer-term worries about the health and lifestyle implications of diabetes. Youths' reported coping strategies are generally consistent with existing coping frameworks, though our data suggest some possible refinements. Social support emerged as an important coping strategy for all age groups. Thus, interventions supporting youth in building and strengthening their social networks may be particularly beneficial in helping youth cope with their diabetes-related worries across development.

Development and delivery of a brief family behavioral intervention to support continuous glucose monitor use in young children with type 1 diabetes

BACKGROUND

Despite potential glycemic benefits of continuous glucose monitor (CGM) use in young children with type 1 diabetes, psychosocial and behavioral challenges may interfere with sustained use. We developed a 5-session family behavioral intervention (FBI) to support CGM use.

OBJECTIVE

We report on the multi-step development of the FBI, training interventionists, implementation in a 14-site clinical trial, and participant satisfaction.

METHODS

A multidisciplinary team created the FBI based on mixed-methods (i.e., survey data, qualitative research) preliminary work with parents of young children. Investigators trained non-physician staff to deliver the 5 sessions per an intervention manual. Trial participants received the FBI either during the first (FBI group, n = 50) or second 6-months (Crossover group, n = 44) of the 1-year trial. Investigators listened to session recordings to rate intervention fidelity, and participants rated satisfaction with the FBI.

RESULTS

The complete 5-session FBI was delivered to 89% of participants, in-person (73%) or by telephone (23%). Sessions lasted 23 min on average, and fidelity was high across sessions. Over 80% of participants rated very high satisfaction with all aspects of the FBI and offered few recommendations for improvement.

CONCLUSIONS

Having been developed based on experiences and input of families of young children with type 1 diabetes, the FBI represented a novel behavioral approach to enhance sustained CGM use during a challenging developmental period. Evidence of strong feasibility and acceptability supports its potential for implementation in research and clinical care. As diabetes technologies evolve, the FBI may continue to be refined to address parents' most relevant concerns.

'I don't sleep through the night': Qualitative study of sleep in type 1 diabetes

AIMS

Individuals with type 1 diabetes (T1D) experience greater sleep disturbances than people without diabetes. However, the nature, causes and effects of sleep disruption in individuals with T1D and their family are not well understood. The purpose of this study was to explore and characterise the perspectives of parents, partners and individuals with diabetes about T1D-related sleep issues.

METHODS

Participants included 44 youth and adults with T1D (ages 9-69), 24 parents of youth with T1D, and 14 partners of adults with T1D, recruited from diabetes clinics at two academic medical centres in the Southwestern and Midwestern United States. Semi-structured qualitative interviews were transcribed verbatim, coded and analysed using hybrid thematic analysis.

RESULTS

We identified two central themes: Emotional Distress and Sleep Disruption. Each theme had multiple subthemes, and the two central themes were related to one another via a shared subtheme, Worry Impacting Sleep.

CONCLUSIONS

Complex T1D-related emotional and behavioural factors both contributed to and resulted from sleep difficulties. Diabetes care providers should routinely assess for sleep concerns in people with T1D and their parents and partners. It may be important to consider both diabetes-related causes of sleep disruptions and potential impacts on self management and emotional functioning.

Peer-support intervention for African American and Latino parents to improve the glycemic control trajectory among school-aged children with type 1 diabetes: A pilot and feasibility protocol

Background Type 1 diabetes (T1D) is a common, chronic pediatric health condition with complicated management demands. African American and Latino children with T1D have troubling disparities in glycemic outcomes and acute complications. While there are empirically supported behavioral interventions to support disease management in youth with T1D, there are few that specifically aim to reduce health disparities in this population. While collaborative parent involvement with the child with T1D management tasks is important to promote optimal glycemic outcomes during childhood, our formative research identified multiple individual, family, and broader system factors that impede or facilitate collaborative parental involvement among African American and Latino parents of children with T1D. Methods This paper describes the development, design, and study protocol for the Type 1 Diabetes Empowerment And Management (TEAM) pilot trial. The TEAM intervention is a novel, group-based behavioral intervention designed to enhance collaborative involvement in T1D management for African American and Latino parents of children aged 5-10. This randomized pilot trial's primary aim is to evaluate the TEAM intervention's feasibility and acceptability. The secondary aim is to examine preliminary intervention outcomes (i.e., children's HbA1c, treatment adherence, collaborative parent involvement in T1D management, parent/child quality of life, and parent's diabetes-related distress, depressive symptoms, and self-efficacy) compared to usual T1D care. Discussion The trial will provide preliminary information about whether optimizing appropriate parent involvement during the school-age years may increase T1D treatment adherence and stabilize or improve glycemic control in African American and Latino school-aged children.

Medication adherence in young adults with youth-onset type 2 diabetes: iCount, an observational study

AIMS

To assess prevalence of, and factors associated with, medication adherence of young adults with youth-onset type 2 diabetes.

METHODS

Oral hypoglycaemia agent (OHA) adherence was measured with unannounced telephone pill counts, insulin adherence was self-reported. Those taking ≥ 80% of pills/insulin were classified "high-adherent," <80% of pills/insulin "low-adherent." Analyses included unadjusted, and adjusted linear and logistic regressions assessing associations of participant factors with adherence.

RESULTS

For people taking OHAs (N = 212, mean age 26 yrs, 67% women, 18% non-Hispanic White, 35% non-Hispanic Black, 41% Hispanic), 69.8% were low-adherent. HbA1c was lower in the high-adherent group (9.2%/77 mmol/mol vs. 10.0%/86 mmol/mol, p < 0.04). More non-Hispanic Blacks were low-adherent (85.7%) than Hispanics (60.2%) and non-Hispanic whites (55.3%, p < 0.002); 91.4% of participants without healthcare coverage were low-adherent vs. 65.5% of those with coverage (p < 0.004). After adjustment, gender (p = 0.024), race/ethnicity (p < 0.001) and healthcare coverage (p = 0.001) remained related to OHA adherence. For insulin (N = 192), 37% were low-adherent. HbA1c was associated with insulin adherence (low = 11.2%/99 mmol/mol vs. high = 10.0%/86 mmol/mol, p < 0.001) with and without adjustment.

CONCLUSIONS

Young adults with youth-onset type 2 diabetes, especially females, non-Hispanic Blacks and those without healthcare coverage, commonly had low-OHA adherence. Glycaemic control was also poor. Interventions to improve medication adherence are needed for this vulnerable group.

Here for You: A Review of Social Support Research in Young Adults With Diabetes

Living with and managing diabetes is challenging during young adulthood, and social support may help relieve or minimize the burdens young adults with diabetes experience. This article reviews the types and sources of support young adults with diabetes receive and their associations with behavioral, psychosocial, and glycemic outcomes. Intervention research integrating social support and future directions for care are discussed.

'La Vida Normal': Young people adapting to Type 1 diabetes in Bolivia

OBJECTIVES

To identify challenges and coping strategies of young people with Type 1 diabetes (T1D) and their families in Bolivia through qualitative analysis of interviews with beneficiaries of Centro Vivir con Diabetes (CVCD), a diabetes health center supported by the International Diabetes Federation Life for a Child (LFAC) program.

METHODS

Eighteen young people aged 14-33 and at least one caregiver participated in semi-structured interviews in five cities in Bolivia from May to June 2016. Interviews were recorded, transcribed, and analyzed using inductive thematic analysis.

RESULTS

Participants described needing guidance at diagnosis and facing stigma in communities. Young people expressed that life with T1D was 'la vida normal' (a normal life), although interpretations of normalcy varied. For some, 'la vida normal' meant resistance to T1D; for others it indicated acceptance.

DISCUSSION

Access to interdependent spheres of support allowed young people to form a new normal around T1D. Receiving supplies through the CVCD/LFAC partnership maintained family connection to clinical care, CVCD education helped families share in T1D management, and peer support mitigated stigma for young people. Programs like CVCD that combine supply-based aid with clinical education for whole families, create effective support for young people with T1D in low- and middle-income countries.

The Diabetes-Specific Risk-Taking Inventory: Piloting a New Measure for Adolescents With Type 1 Diabetes

OBJECTIVE

We sought to develop and pilot a new measure, the Diabetes-Specific Risk-Taking Inventory (DSRI), to assess unhealthy risk-taking behaviors among adolescents with type 1 diabetes.

METHODS

Thirteen diabetes health care providers, 30 adolescents with type 1 diabetes (aged 15-19 years, 60% female, mean A1C 8.7% [72 mmol/mol], and 33% on insulin pumps), and the adolescents' caregivers rated the perceived riskiness of each item on the DSRI. Adolescents completed the DSRI, for which they reported how often they engaged in 34 behaviors that could place them at risk for acute complications of type 1 diabetes or out-of-range blood glucose levels. Adolescents also completed the risk-taking subscale from the Risk-Taking and Self-Harm Inventory for Adolescents, and parents completed the parent-proxy Diabetes Management Questionnaire. Mean A1C during the previous year was obtained via medical chart review.

RESULTS

Results indicated good content validity and feasibility for using the DSRI in a research context, as 100% of adolescents who consented to the study completed the measure. The DSRI was positively correlated with general risk-taking and negatively correlated with diabetes management, indicating preliminary evidence of convergent validity. The DSRI also correlated with A1C.

CONCLUSION

This pilot study extends our previous work in developing a conceptual model for illness-specific risk-taking. The DSRI is a promising new measure to assess illness-specific risk-taking, including unhealthy risk-taking behaviors, for adolescents with type 1 diabetes.

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

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. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

"We are a family with diabetes": Parent perspectives on siblings of youth with type 1 diabetes

Having a child with type 1 diabetes (T1D) impacts the entire family system. Parental distress and burden have been well studied, but other family members, including siblings, have received little attention. Based on research about family life and sibling experiences in other chronic condition populations (e.g., autism, cancer), we expected parents of youth with T1D would report that siblings participated in T1D management and that T1D had a psychological impact on siblings. As part of a larger qualitative study, parents of youth with T1D age 5-17 (M = 10.8 ± 3.6 years) participated in semistructured interviews about T1D-specific health-related quality of life. For this study, we conducted secondary analyses on transcripts from 20 parents (95% mothers) from households with at least 1 sibling of the child with T1D. Three themes emerged: (a) siblings share the workload and help with T1D management, (b) T1D takes an emotional toll on siblings, and (c) parents feel guilty about prioritizing T1D over siblings' needs and desires. Parents recognized siblings have impactful roles in T1D management and family functioning. Future research into these themes can guide clinical and research efforts to develop sibling-inclusive resources and interventions for families with T1D. Enhancing family-focused interventions to recognize and support the needs of siblings may ultimately improve family T1D-related quality of life.

Design and psychometrics for new measures of health-related quality of life in adults with type 1 diabetes: Type 1 Diabetes and Life (T1DAL)

AIMS

To use a three-phase process to develop and validate new self-report measures of diabetes-specific health-related quality of life (HRQOL) for adults with type 1 diabetes. We report on four versions of the Type 1 Diabetes and Life (T1DAL) measure for people age 18-25, 26-45, 46-60, and over 60 years.

METHODS

We first conducted qualitative interviews to guide measure creation, then piloted the draft measures. We evaluated psychometric properties at six T1D Exchange Clinic Network sites via completion of T1DAL and validated measures of related constructs. Participants completed the T1DAL again in 4-6 weeks. We used psychometric data to reduce each measure to 23-27 items in length. Finally, we obtained participant feedback on the final measures.

RESULTS

The T1DAL-Adult measures demonstrated good internal consistency (α = 0.85-0.88) and test-retest reliability (r = 0.77-0.87). Significant correlations with measures of general quality of life, generic and diabetes-specific HRQOL, diabetes burden, self-management, and glycemic control demonstrated validity. Factor analyses yielded 4-5 subscales per measure. Participants were satisfied with the final measures and reported they took 5-10 min to complete.

CONCLUSIONS

The strong psychometric properties of the newly developed self-report T1DAL measures for adults with type 1 diabetes make them appropriate for use in clinical research and care.

Associations of diabetes self-management characteristics, HbA1c, and psychosocial outcomes with depressive symptoms in a contemporary sample of adolescents with type 1 diabetes

AIMS

We sought to examine the associations between diabetes self-management, HbA1c, and psychosocial outcomes with the frequency of depressive symptoms.

METHODS

We surveyed 301 teens (50% male, 22% non-white), mean age of 15.0±1.3 years, diabetes duration of 6.5±3.7 years. Biomedical variables: daily frequency of blood glucose monitoring of 4.5±1.9, 63% insulin pump use, mean HbA1c 8.5±1.1% (69±12 mmol/mol); 15% of the sample achieved the target HbA1c of <7.5% (<58 mmol/mol).

RESULTS

Nearly 1 in 5 (18%, n=54) adolescents reported significant depressive symptoms and, of those participants, slightly under half reported moderate/severe depressive symptoms. Teens with moderate/severe depressive symptoms (CES-D scores ≥24) were more likely to be female, have parents without a college education, and not utilize insulin pumps. Teens with more depressive symptoms reported higher diabetes family conflict, higher diabetes burden, and lower quality of life. In the group reporting no depressive symptoms (10%), scores on psychosocial variables and diabetes treatment variables were the most favorable.

CONCLUSION

In our sample, the presence of depressive symptoms appears to relate to both diabetes treatment and quality of life. In addition, studying teens without depressive symptoms can help us learn more about protective factors that potentially buffer against depressive symptoms and that are associated with better outcomes.

Defining features of diabetes resilience in emerging adults with type 1 diabetes

BACKGROUND

Emerging adulthood presents unique challenges for type 1 diabetes (T1D) management. Barriers to achieving optimal diabetes outcomes have been studied but less is known about how emerging adults overcome these challenges. Characterizing emerging adults' protective factors may help guide T1D care during this developmental period. We anticipated identifying social, cognitive, and behavioral protective factors and were open to additional themes.

METHODS

We analyzed transcripts from semi-structured qualitative interviews with 62 emerging adults (age 18-24 years) with T1D using hybrid thematic analysis. Interviews queried about participants' perspectives on diabetes management challenges, how they overcome challenges, and diabetes resilience.

RESULTS

We categorized responses into three types of protective factors: (a) Social: Interpersonal strategies such as obtaining tangible support (especially from parents) and emotional support from friends, medical professionals, and community leaders. (b) Cognitive: Believing one can live a "normal" life with T1D, benefit-finding, and viewing diabetes management as an important part of life. (c) Behavioral: Proactively planning for diabetes challenges, maintaining a consistent routine while allowing for flexibility, balancing diabetes and non-diabetes activities, and using diabetes-specific and general technologies to support self-management.

CONCLUSIONS

The adaptive approaches emerging adults with T1D use to handle the challenges of diabetes include seeking interpersonal support, managing their thoughts about T1D, and taking specific actions to prevent or resolve challenges. Helping emerging adults identify and strengthen their protective factors has potential to affect clinical outcomes. Strengths-based assessment and clinical attention to protective factors may prepare adolescents to successfully manage the challenges of transition to adult care.

Profiles of Depressive Symptoms and Diabetes Distress in Preadolescents With Type 1 Diabetes

OBJECTIVES

Diabetes distress and depressive symptoms are common psychosocial concerns for people with diabetes. These are related, yet distinct, mood states, which have each been related to diabetes management and glycated hemoglobin (A1C) among adolescents and adults with diabetes. However, they have not been examined concurrently in preadolescents with type 1 diabetes. Understanding the overlaps and distinctions between diabetes distress and depressive symptoms in youth would help guide decisions about psychosocial screening in diabetes clinical practice. In this study, we aimed to categorize preadolescents based on clinical cutoffs of concurrently administered measures of depressive symptoms and diabetes distress, and identify clinical and demographic characteristics of each group.

METHODS

One hundred eighty youth (age range, 9 to 13 years; age [mean ± standard deviation], 11.3±1.3 years; 55% female; 56% Caucasian; mean A1C, 8.4±1.6% [68 mmol/mol]) completed measures of diabetes distress, depressive symptoms and quality of life. Daily blood glucose monitoring frequency was calculated from meter download. A1C values were obtained from electronic medical records.

RESULTS

Depressive symptoms and diabetes distress each significantly correlated with A1C and quality of life. Although most (69%) participants had no clinically significant elevations in either diabetes distress or depressive symptoms, 14% had elevated depressive symptoms only and 17% had elevated distress without concurrent elevated depressive symptoms. Groups differed based on A1C, quality of life and insurance status.

CONCLUSIONS

Routine assessment of both depressive symptoms and diabetes distress may help to identify preadolescents with type 1 diabetes who require psychosocial support.

Assessing Health-Related Quality of Life in Children and Adolescents with Diabetes: Development and Psychometrics of the Type 1 Diabetes and Life (T1DAL) Measures

OBJECTIVE

To develop and validate new measures of diabetes-specific health-related quality of life (HRQOL) for people with type 1 diabetes (T1D) that are brief, developmentally appropriate, and usable in clinical research and care. Here we report on the phases of developing and validating the self-report Type 1 Diabetes and Life (T1DAL) measures for children (age 8-11) and adolescents (age 12-17).

METHODS

Measure development included qualitative interviews with youth and parents (n = 16 dyads) followed by piloting draft measures and conducting cognitive debriefing with youth (n = 9) to refine the measures. To evaluate the psychometric properties, children (n = 194) and adolescents (n = 257) at three T1D Exchange Clinic Network sites completed the age-appropriate T1DAL measure and previously validated questionnaires measuring related constructs. Using psychometric data, the investigators reduced the length of each T1DAL measure to 21 and 23 items, respectively, and conducted a final round of cognitive debriefing with six children and adolescents.

RESULTS

The T1DAL measures for children and adolescents demonstrated good internal consistency (α = 0.84 and 0.89, respectively) and test-retest reliability (r = 0.78 and 0.80, respectively). Significant correlations between the T1DAL scores and measures of general quality of life, generic and diabetes-specific HRQOL, diabetes burden, and diabetes strengths demonstrated construct validity. Correlations with measures of self-management (child and adolescent) and glycemic control (adolescent only) demonstrated criterion validity. Factor analyses indicated four developmentally specific subscales per measure. Participants reported satisfaction with the measures.

CONCLUSIONS

The new T1DAL measures for children and adolescents with T1D are reliable, valid, and suitable for use in care settings and clinical research.

Diabetes distress and HbA1c in racially/ethnically and socioeconomically diverse youth with type 1 diabetes

BACKGROUND

Diabetes distress, the emotional burden of caring for the chronic demands of diabetes, has not been well described in children and preadolescents with type 1 diabetes (T1D). This gap is particularly evident among youth of lower socioeconomic status (SES) and/or racial/ethnic minorities. Since these groups are more likely to have disparities in health outcomes and healthcare related to their diabetes, factors that could potentially improve glycemic and other diabetes-related outcomes should be studied closely.

OBJECTIVE

We hypothesized that (a) diabetes distress levels would be elevated in children with markers of lower SES and those of racial/ethnic minorities, and (b) higher HbA1c would be predicted by higher diabetes distress levels, when controlling for race/ethnicity, SES, and clinical covariates.

METHODS

One hundred and eighty-seven youth age 9 to 13 with T1D completed age-appropriate Problem Areas in Diabetes (PAID) questionnaires using a web-based portal during routine diabetes care visits.

RESULTS

PAID scores were significantly elevated in youth who had surrogate markers of lower SES and who were from racial/ethnic minority backgrounds. In multivariate models including race/ethnicity or the SES variables and controlling for clinical covariates, the factor most predictive of higher HbA1c was elevated PAID score.

CONCLUSIONS

Diabetes distress is elevated in a younger population of children with T1D who are from racial/ethnic minority backgrounds or have markers of lower SES. Interventions that target distress and/or expand the safety net in these populations could potentially improve glycemic outcomes.

Type 1 Doing Well: Pilot Feasibility and Acceptability Study of a Strengths-Based mHealth App for Parents of Adolescents with Type 1 Diabetes

Background: We evaluated the feasibility and acceptability of a pilot behavioral intervention delivered to parents of adolescents with type 1 diabetes (T1D) via mobile-friendly web app. The Type 1 Doing Well app aimed to promote supportive family diabetes management by helping parents recognize and reinforce teens' positive diabetes-related behaviors ("strengths"). Methods: Parents (n = 80, 74% recruitment) of adolescents (age range = 12-17 years, M = 15.3 ± 1.5 years, 59% female, 56% insulin pump, M hemoglobin A1c (HbA1c) = 9.0% ± 2.1%) were randomized 2:1 to intervention or control (i.e., usual medical care with or without app) for 3-4 months between diabetes appointments. The app prompted parents daily to track adolescents' strengths and generated weekly summaries of their teen's top strengths. Parents could access a library of text messages to praise their teens. Exploratory pre/post data included questionnaires (98% completed) and HbA1c. Results: Parents used the app for M = 106.1 ± 37.1 days, logging in ≥once/day on 80% of days. Ninety-one percent of parents used the app ≥2 days/week on average. Parents viewed M = 5.6 ± 4.7 weekly summaries and "favorited" 15 praise texts in the library. App acceptability ratings (7-point scale) were high: Satisfaction 5.0 ± 1.5, Usefulness 4.8 ± 1.5, Ease of Use 6.2 ± 0.8, and Ease of Learning 6.5 ± 0.8. Parents (n = 48) and adolescents (n = 47) gave positive feedback and suggestions via qualitative interviews. There were no significant between-group differences for change in exploratory outcomes (HbA1c, questionnaires). Conclusions: Type 1 Doing Well was feasible to deliver and highly acceptable and engaging for parents of adolescents with T1D. It may have a larger impact on behavioral or clinical outcomes as part of a multicomponent intervention protocol. Trial Registration: ClinicalTrials.gov NCT02877680.

Sources and Valence of Information Impacting Parents' Decisions to Use Diabetes Technologies in Young Children <8 Years Old with Type 1 Diabetes

There are multiple information sources available to assist families in learning about rapidly advancing diabetes technologies as care options for their children. This study explored where and from whom families of young children with type 1 diabetes get information about diabetes technologies and the valence (positive vs. negative) of that information. Semi-structured interviews were conducted with parents (86% mothers) of 79 youth <8 years old with type 1 diabetes for ≥6 months, ([mean ± standard deviation] age 5.2 ± 1.5 years, diabetes duration 2.4 ± 1.3 years, 77% white, A1c 63 ± 10 mmol/mol [7.9 ± 0.9%], 66% pump-treated, 58% using continuous glucose monitors [CGMs]). Interviews were transcribed and underwent content analysis to derive central themes. Most parents reported learning about new technologies from three direct sources: diabetes care providers, people with diabetes, and caregivers of children with diabetes. Parents also cited three indirect sources of information: online forums, publications, and diabetes-specific conferences. Parents reported hearing primarily positive things about technologies. Families not using pump and/or CGM noted reluctance to use technology due to family-specific concerns (e.g., cost, child's unwillingness to wear device) rather than information from outside sources. In this subset of parents, many still expressed willingness to initiate use once family-specific concerns were resolved. Parents of young children received largely positive information about diabetes technologies, primarily from health care providers and others familiar with using devices personally or for their children. To maximize diabetes technology use in young children, it is incumbent upon providers to ensure families receive balanced realistic information about benefits and barriers.

Time spent outside of target glucose range for young children with type 1 diabetes: a continuous glucose monitor study

AIM

To assess the associations between demographic and clinical characteristics and sensor glucose metrics in young children with type 1 diabetes, using masked, continuous glucose monitoring data from children aged 2 to < 8 years.

RESEARCH DESIGN AND METHODS

The analysis included 143 children across 14 sites in the USA, enrolled in a separate clinical trial. Eligibility criteria were: age 2 to <8 years; type 1 diabetes duration ≥3 months; no continuous glucose monitoring use for past 30 days; and HbA_1c concentration 53 to <86 mmol/mol (7.0 to <10.0%). All participants wore masked continuous glucose monitors up to 14 days.

RESULTS

On average, participants spent the majority (13 h) of the day in hyperglycaemia (>10.0 mmol/l) and a median of ~1 h/day in hypoglycaemia (<3.9 mmol/l). Participants with minority race/ethnicity and higher parent education levels spent more time in target range, 3.9-10.0 mmol/l, and less time in hyperglycaemia. More time in hypoglycaemia was associated with minority race/ethnicity and younger age at diagnosis. Continuous glucose monitoring metrics were similar in pump and injection users.

CONCLUSIONS

Given that both hypo- and hyperglycaemia negatively impact neurocognitive development, strategies to increase time in target glucose range for young children are needed.

Text Message Intervention for Teens with Type 1 Diabetes Preserves HbA1c: Results of a Randomized Controlled Trial

Aims: Teens with type 1 diabetes (T1D) often struggle with diabetes self-management, which may lead to suboptimal self-care and worsening hemoglobin A1c (HbA1c). Innovative strategies are needed to improve self-care and protect against glycemic decline, especially during adolescence. We aimed to assess the impact on HbA1c of two interventions, problem-solving and text messaging, in teens with T1D. Methods: In a two-site randomized controlled trial, teens (N = 301) 13-17 years of age with T1D were randomized to one of the four groups using a 2 × 2 factorial design: Teenwork (TW), Text Messaging (Text), TW+Text, or Usual Care. TW intervention included problem-solving aimed at improving T1D self-care for blood glucose (BG) monitoring and insulin bolus dosing. Text intervention involved text reminders to check BG. The primary outcome was change in HbA1c from baseline to 12 months. Results: At baseline, teens (51% female, 78% white, 59% pump-treated) were (mean ± SD) 15.0 ± 1.3 years, had diabetes duration of 6.5 ± 3.7 years, and HbA1c 8.5% ± 1.1%. There was no significant difference in HbA1c over time by study group. Responsiveness to text reminders by teens in the TEXT and TW+TEXT predicted glycemic benefit; TW did not. Conclusions: Despite no HbA1c difference by study group, greater response to text message reminders to check BG led to better glycemic control and no deterioration in HbA1c; the problem-solving intervention did not. Given the high penetration of mobile phones and the wide acceptance of text messaging among teens in general, it is encouraging that a text messaging intervention can preserve HbA1c, thus preventing the expected deterioration in glycemic control often seen in teens with T1D.

Featured Article: Strengths-Based, Clinic-Integrated Nonrandomized Pilot Intervention to Promote Type 1 Diabetes Adherence and Well-Being

Objective

Given persistent challenges achieving optimal diabetes outcomes in adolescence, new interventions to support disease self-management and emotional well-being are needed. Approaches that emphasize adolescents' positive behaviors and attitudes ("strengths") are designed to incorporate positive provider communications into clinical encounters to encourage youths' engagement in adherence behaviors and enhance well-being.

Methods

This pilot study tested the feasibility, acceptability, and preliminary outcomes of a brief, strengths-based behavioral intervention for adolescents with type 1 diabetes. Adolescents (age 12-17 years) and parents were recruited, consented, and completed baseline and postintervention questionnaires. There was no randomization to a control group, and all participants received the pilot intervention. At the start of two clinic visits, diabetes care providers followed a semi-structured script to reinforce adolescents' diabetes-related strengths and adherence behaviors.

Results

Of 116 eligible families, 84 consented and 64 completed baseline (M age = 15.0 ± 1.8 years, 56% female, 69% White, M HbA1c = 8.6 ± 1.6%). Providers reported the intervention usually (95%) took <10 min to deliver. Participants and providers enjoyed the intervention and would like to see it as part of routine clinical care. Pre-post data indicated significant improvements in youth-rated diabetes strengths, adherence, burden, and relationship with provider, parent-reported diabetes burden, and provider-rated relationship with family (p < .05). Objectively measured adherence and glycemic control did not change.

Conclusions

This brief strengths-based, clinic-integrated intervention was feasible to conduct and stakeholders were satisfied. This intervention holds promise to have a positive impact on adolescents' diabetes adherence, well-being, and provider relationships. Lessons were learned to improve implementation and participant experience for a larger study.

"I'm essentially his pancreas": Parent perceptions of diabetes burden and opportunities to reduce burden in the care of children <8 years old with type 1 diabetes

BACKGROUND

Across all age groups, management of type 1 diabetes (T1D) places substantial responsibility and emotional burden upon families. This study explored parent perceptions of the burdens of caring for very young children with T1D.

METHODS

Semi-structured qualitative interviews were conducted with parents (85% mothers) of 79 children with T1D, aged 1 to <8 years old, from four diverse pediatric diabetes clinical centers. Interviews were transcribed, coded, and analyzed using hybrid thematic analysis to derive central themes.

RESULTS

Youth (77% White) had T1D for ≥6 months: age (M ± SD) 5.2 ± 1.5 years, diabetes duration 2.4 ± 1.3 years, and A1c 63 ± 10 mmol/mol (7.9 ± 0.9%); 66% used an insulin pump and 61% used CGM. Three major themes emerged related to diabetes burdens: (a) the emotional burden of diabetes on themselves and their children, (b) the burden of finding, training, and trusting effective secondary caregivers to manage the child's diabetes, and (c) suggestions for how more comprehensive, personalized diabetes education from healthcare providers for parents and secondary caregivers could help reduce parent burden and worry.

CONCLUSIONS

In families with very young children with T1D, parental perceptions of the burden of managing diabetes are common and could be mitigated by tailored education programs that increase parent knowledge, bolster parents' confidence in themselves, and increase trust in their secondary caregivers to manage diabetes. Reduced parental burden and increased caregiver knowledge may positively impact child's glycemic control, as well as improve parent and child quality of life.

Adherence to multiple medications in the TODAY (Treatment Options for type 2 Diabetes in Adolescents and Youth) cohort: effect of additional medications on adherence to primary diabetes medication

Background Non-adherence to diabetes medication leads to poor outcomes and increased healthcare costs. Multiple factors affecting adherence in adults with type 2 diabetes (T2D) have been identified, but pediatric data is sparse. We aimed to determine whether initiation of additional oral medications or insulin affects adherence to primary study medication (PSM) in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) study. Methods Six hundred and ninety-nine youth (aged 10-17 years) with recent-onset T2D were randomized in the TODAY study. Participants were categorized as adherent (≥80% taken by pill count) or non-adherent (<80%), and adherence was compared between those on additional medications or not. Subgroup analyses to assess influence of race/ethnicity, gender, medication type, or depression were performed. Results At 36 months, 46.3% of participants were taking additional oral medications and 31.9% were on insulin. There was no difference in study medication adherence with additional oral medications (55.1%, 67.1%, and 56.7% at month 36 in those prescribed 0, 1, or 2+  additional medications; p = 0.16). Girls on oral contraceptives (OC) had higher adherence (65.2% vs. 55.8% at month 36; p = 0.0054). Participants on insulin had lower adherence (39.7% vs. 59.3% at 36 months; p < 0.0001). There was decreased adherence in participants with baseline depression (p = 0.008). Conclusions Additional oral medications did not influence adherence to diabetes medications in TODAY. Addition of insulin led to reduced adherence. In subgroup analyses, OC use was associated with higher adherence in girls, while baseline depression was associated with lower adherence overall. Further studies examining potentially modifiable risk factors of adherence in pediatric T2D are needed.

Diabetes disclosure strategies in adolescents and young adult with type 1 diabetes

OBJECTIVE

Adolescence and young adulthood have social and developmental challenges that can impact type 1 diabetes (T1D) management. New relationships (e.g. friends, schoolmates, dating partners, teachers, employers) introduce opportunities for disclosure of T1D status. Characterizing how adolescents and young adults (AYAs) disclose having T1D to others may help inform clinical strategies to help AYAs ensure their safety by obtaining social support.

METHODS

As part of a study about diabetes health-related quality of life across the lifespan, transcriptions of semi-structured qualitative interviews with AYAs with T1D (n = 16, age 12-25 years, mean age 18.7 ± 4.9, 38% female) were coded to derive themes related to T1D disclosure.

RESULTS

Participants described three disclosure strategies: (1) Open Disclosure: shares T1D status in straightforward, direct manner and readily requests diabetes-related support; (2) Disclosure Hesitancy: reluctant to tell others about or actively hides having T1D; (3) Passive Disclosure: discloses T1D via other people (e.g., parents) or through others' observation of T1D management tasks.

CONCLUSION

AYAs may benefit from guidance in approaches to informing others about having T1D in different contexts. Identifying individuals' use of these strategies can inform education and intervention strategies aimed at engaging AYAs in healthy T1D-related disclosure to seek and receive support.

Assessing strengths of children with type 1 diabetes: Validation of the Diabetes Strengths and Resilience (DSTAR) measure for ages 9 to 13

BACKGROUND

Adaptive diabetes-specific attitudes and behaviors, known as diabetes strengths, relate to positive self-management and quality of life outcomes in type 1 diabetes (T1D), but have not been studied in preadolescence. To facilitate strengths-based care and research on this topic, we developed and evaluated the psychometric properties of a measure of diabetes strengths for children age 9 to 13.

METHODS

Participants were 187 children receiving care for T1D at a tertiary care children's hospital. They completed the 12-item self-report Diabetes Strengths and Resilience scale for children (DSTAR-Child), which we adapted from a measure validated for adolescents. Youth completed the DSTAR-Child twice, and measures of relevant constructs at baseline: general and diabetes-related quality of life, depressive symptoms, and diabetes distress. Parents rated children's engagement in self-management behaviors and general resilience. We extracted HbA1c from the medical record.

RESULTS

The DSTAR-Child total score demonstrated reliability, including internal consistency and stability across two time points. The total score was significantly associated in expected directions with psychosocial measures and glycemic control but not self-management behaviors. In confirmatory factor analyses, the best-fitting structure contained two latent factors tapping intrapersonal and interpersonal strengths. Resulting subscale scores also appeared reliable and valid.

CONCLUSIONS

This brief, practical measure of diabetes strengths demonstrated sound psychometric properties. Diabetes strengths appeared unrelated to self-management behaviors, perhaps because of the primary role of adult caregivers in T1D management for preadolescents. As a research and clinical tool, the DSTAR-Child can facilitate greater understanding of diabetes strengths and inform strengths-based strategies to foster resilient T1D outcomes.

Using Relational Agents to Promote Family Communication Around Type 1 Diabetes Self-Management in the Diabetes Family Teamwork Online Intervention: Longitudinal Pilot Study

Background

Family conflict can reduce adolescent adherence to type 1 diabetes management tasks. The Family Teamwork in-person intervention was shown to be efficacious in reducing conflict and low adherence to diabetes-related tasks. Its reach and potential impact, however, were limited by the need to deliver the intervention sessions in person. Relational agents (ie, computerized versions of humans) have been shown to appeal to diverse audiences and may be an acceptable replacement for a human in technology-based behavior change interventions.

Objective

The purpose of this paper is to present the results of a pilot study assessing feasibility and acceptability of Diabetes Family Teamwork Online, an adapted version of the Family Teamwork intervention, delivered over the internet and guided by a relational agent.

Methods

Parent-adolescent dyads were recruited through a diabetes care clinic at a large tertiary care hospital in the southwestern United States. A one-group design, with assessments at baseline, immediate postintervention, and 3 months later, was used to assess feasibility. A priori feasibility criteria included an assessment of recruitment, completion, attrition, program satisfaction, therapeutic alliance, attitudes toward the relational agent, and data collection. The institutional review board at Baylor College of Medicine approved the protocol (H-37245).

Results

Twenty-seven adolescents aged 10 to 15 years with type 1 diabetes and their parents were enrolled. Criteria used to assess feasibility were (1) recruitment goals were met (n=20), (2) families completed ≥75% of the modules, (3) attrition rate was ≤10%, (4) program satisfaction was high (≥80% of families), (5) therapeutic alliance was high (average score of ≥60/84), (6) families expressed positive attitudes toward the relational agent (average item score of ≥5 on ≥4 items), (7) ≥80% of data were collected at post 1 and post 2, and (8) few technical issues (≤10%) occurred during intervention delivery. All feasibility criteria were met. Qualitative data confirmed that adolescents and parents had positive reactions to both the content and approach.

Conclusions

The Diabetes Family Teamwork Online intervention proved to be a feasible and acceptable method for enhancing communication around diabetes management tasks in families with an adolescent who has type 1 diabetes.

Can we predict which species win when new habitat becomes available?

Land cover change is a key component of anthropogenic global environmental change, contributing to changes in environmental conditions of habitats. Deforestation is globally the most widespread and anthropogenically driven land cover change leading to conversion from closed forest to open non-forest habitat. This study investigates the relative roles of geographic features, characteristics of species climatic niche and species traits in determining the ability of open-habitat plant species to take advantage of recently opened habitats. We use current occurrence records of 18 herbaceous, predominantly open-habitat species of the genus Acaena (Rosaceae) to determine their prevalence in recently opened habitat. We tested correlation of species prevalence in anthropogenically opened habitat with (i) geographic features of the spatial distribution of open habitat, (ii) characteristics of species climatic niche, and (iii) species traits related to dispersal. While primary open habitat (naturally open) was characterised by cold climates, secondary open habitat (naturally closed but anthropogenically opened) is characterised by warmer and wetter conditions. We found high levels of variation in the species prevalence in secondary open habitat indicating species differences in their ability to colonise newly opened habitat. For the species investigated, geographical features of habitat and climatic niche factors showed generally stronger relationships with species prevalence in secondary open habitat than functional traits. Therefore, for small herbaceous species, geographical features of habitat and environmental factors appear to be more important than species functional traits for facilitating expansion into secondary open habitats. Our results suggested that the land cover change might have triggered the shifts of factors controlling open-habitat plant distributions from the competition with forest trees to current environmental constraints.

Benefits and Barriers of Continuous Glucose Monitoring in Young Children with Type 1 Diabetes

Background: Continuous glucose monitoring (CGM) has potential to address challenges of type 1 diabetes (T1D) management for young children. CGM use is increasing, yet remains underutilized. Characterizing parents' experiences with CGM can inform clinical strategies to help parents make decisions about diabetes management, overcome obstacles to initiating and sustaining CGM use, and maximize benefits of CGM use in their children's diabetes care. Methods: Transcripts from semistructured qualitative interviews with 55 parents of children aged 1 to <8 years, with T1D duration ≥6 months, and whose child currently or previously used CGM were coded and analyzed to derive themes about their experiences with CGM. Results: Participants were 88% mothers and the mean child age was 5.0 ± 1.5 years. Parents described benefits of CGM use: decreased worry about glucose excursions, improved sleep, increased sense of safety with children who cannot recognize or express symptoms of hypo- or hyperglycemia, and greater comfort with other caregivers, especially using remote monitoring functionality when away from children. Challenges included painful insertions, wearing multiple devices on small bodies, disruptive alerts, data gaps due to lost signals, skin/adhesive problems, and difficulty interpreting the amount of information generated by CGM. For some, the challenges outweighed potential benefits and they stopped CGM use. Conclusions: CGM may address unique challenges of T1D in young children and increase parental comfort with diabetes management, yet there are multiple barriers to initiating or maintaining CGM use. Education and behavioral support to address these benefits and barriers may equip caregivers with skills to address challenges of CGM use.

Text-message responsiveness to blood glucose monitoring reminders is associated with HbA1c benefit in teenagers with Type 1 diabetes

AIMS

To evaluate an 18-month text-messaging intervention in teenagers with Type 1 diabetes and to assess factors associated with text responsiveness and glycaemic benefit.

METHODS

Teenagers with diabetes (N = 147), aged 13-17 years, received two-way text reminders at self-selected times to check blood glucose levels and reply with blood glucose results.

RESULTS

At baseline, the participants (48% boys, 78% white, 63% pump-treated) had a mean ± sd age of 14.9 ± 1.3 years, diabetes duration of 7.1 ± 3.9 years and HbA_1c concentration of 69 ± 12 mmol/mol (8.5 ± 1.1%). The mean proportion of days with ≥1 blood glucose response declined over time (0-6 months, 60 ± 26% of days, 7-12 months, 53 ± 31% of days, 13-18 months, 43 ± 33% of days). Over 18 months, 49% responded with ≥1 blood glucose result on ≥50% of days (high responders). Regression analysis controlling for baseline HbA_1c revealed no significant change in HbA_1c from baseline to 18 months in high responders (P = 0.54) compared with a significant HbA_1c increase in low responders (+0.3%, P = 0.01). In participants with baseline HbA_1c ≥64 mmol/mol (≥8%), high responders were 2.5 times more likely than low responders to have a clinically significant [≥5.5 mmol/mol (≥0.5%)] HbA_1c decrease over 18 months (P < 0.05). In participants with baseline HbA_1c <64 mmol/mol(<8%), high responders were 5.7 times more likely than low responders to have an 18-month HbA_1c <58 mmol/mol (<7.5%; P < 0.05).

CONCLUSIONS

Teenagers with Type 1 diabetes who responded to text reminders on ≥50% of days over 18 months experienced clinically significant glycaemic benefit. There remains a need to tailor interventions to maintain teenager engagement and optimize improvements.

Long-chain n-alkane and n-fatty acid characteristics in plants and soil - potential to separate plant growth forms, primary and secondary grasslands?

Plant-derived lipid molecular proxies can provide insight into present-day soil carbon input and to what extent organic carbon is degraded within soil. To explore whether soil characteristics of 'primary' (i.e., native grasslands above the historic treeline) and 'secondary' (i.e., human-modified grasslands below the historic treeline) grasslands reflect recent and/or past vegetation input we compared lipid characteristics in modern vegetation and soil from 30 locations around the historic treeline (1150 m) in Central Otago, New Zealand. At each location the dominant plant species and the mineral topsoil (0-10 cm) were analyzed for a range of n-alkane and n-fatty acid proxies. Grass/herbs and trees differed in their total n-alkane concentration (88.9 vs 232.6 μg/g plant dry weight), even-over-odd predominance (EOP, 10.2 vs 18.3) and n-C₂₀/n-C₂₄ ratio (2.2 vs 6.4). Soil samples under all plant growth forms had considerably lower n-alkane and n-fatty concentrations than the corresponding plant samples. Soil under grass/herbs had lower (4.1) odd-over-even predominance (OEP) values compared to soil under trees (10.1) indicating that lipid degradation under grass/herbs cover was higher. Principle component analysis demonstrated that soil lipid characteristics reflected the current vegetation cover. Principal component analysis also revealed a separation between 'primary' and 'secondary' grasslands. However, further evaluations are required to confirm the validity of lipid proxies in reconstructing the vegetation history of secondary grasslands.

Positive Well-Being in Youth With Type 1 Diabetes During Early Adolescence

Developmental shifts during early adolescence relate to type 1 diabetes (T1D) self-management, increased risk of emotional distress, and worsening health status. Less is known about positive experiences related to T1D. This study evaluated associations of positive well-being (PWB) with diabetes burden, self-management, and glycemic control. Youth (N = 55, age = 12-13 years; X̄ age = 12.75 + 0.56 years, 50.9% male, 38.2% non-Caucasian) reported PWB, depressive symptoms, and diabetes burden. Parents reported on overall T1D adherence. Adherence behaviors and glycemic control were assessed objectively. Higher PWB correlated with lower depressive symptoms (r s = -.45), less diabetes burden (r s = -.48), and better glycemic control (r s = -.43), all p < .01. When controlling for diabetes duration, higher PWB correlated with lower depressive symptoms and better glycemic control. PWB was not related to demographics or adherence. Initial exploration suggests PWB is related to key diabetes constructs, and maybe valuable to consider along with efforts to support youth with T1D during a vulnerable developmental period.

Screening and support for emotional burdens of youth with type 1 diabetes: Strategies for diabetes care providers

Multiple sources of burden for youth with type 1 diabetes (T1D) impact key outcomes including quality of life, self-management, and glycemic control. Professional diabetes organizations recommend diabetes care providers screen for psychosocial and behavioral challenges and implement strategies to support youth with T1D. The purpose of this article is to review the literature and recommend practical strategies medical providers can use for screening and behavioral support for youth with diabetes and their families. As part of their routine medical care, diabetes care providers are well-positioned to identify and intervene to address emotional distress related to the burdens of living with diabetes. In collaboration with multidisciplinary team members, including psychologists and mental health professionals, medical providers may be able to successfully implement brief behavioral strategies for screening and providing emotional support.

Dexmedetomidine metabolic clearance is not affected by fat mass in obese patients

BACKGROUND

Obesity has been associated with reduced dexmedetomidine clearance, suggesting impaired hepatic function or reduced hepatic blood flow. The aim of this study was to clarify the effect of obesity in dexmedetomidine metabolic clearance.

METHODS

Forty patients, ASA I-III, 18-60 yr old, weighing 47-126 kg, scheduled for abdominal laparoscopic surgery, were enrolled. Anaesthetic agents (propofol, remifentanil, and dexmedetomidine) were dosed based on lean body weight measured by dual X-ray absorptiometry. Serial venous samples were drawn during and after dexmedetomidine infusion. A pharmacokinetic analysis was undertaken using non-linear mixed-effect models. In the modelling approach, the total body weight, lean body weight, and adjusted body weight were first tested as size descriptors for volumes and clearances. Hepatic blood flow, liver histopathology, liver enzymes, and gene expression of metabolic enzymes (UGT2B10 and UGT1A4) were tested as covariates of dexmedetomidine metabolic clearance. A decrease in NONMEM objective function value (ΔOFV) of 3.84 points, for an added parameter, was considered significant at the 0.05 level.

RESULTS

A total of 637 dexmedetomidine serum samples were obtained. A two-compartmental model scaled to measured lean weight adequately described the dexmedetomidine pharmacokinetics. Liver blood flow was a covariate for dexmedetomidine clearance (ΔOFV=-5.878). Other factors, including fat mass, histopathological damage, and differential expression of enzymes, did not affect the dexmedetomidine clearance in the population studied (ΔOFV<3.84).

CONCLUSIONS

We did not find a negative influence of obesity in dexmedetomidine clearance when doses were adjusted to lean body weight. Liver blood flow showed a significant effect on dexmedetomidine clearance.

Strengths-Based Behavioral Intervention for Parents of Adolescents With Type 1 Diabetes Using an mHealth App (Type 1 Doing Well): Protocol for a Pilot Randomized Controlled Trial

Background

Supportive parent involvement for adolescents’ type 1 diabetes (T1D) self-management promotes optimal diabetes outcomes. However, family conflict is common and can interfere with collaborative family teamwork. Few interventions have used explicitly strengths-based approaches to help reinforce desired management behaviors and promote positive family interactions around diabetes care.

Objective

The aim of this protocol was to describe the development of a new, strengths-based behavioral intervention for parents of adolescents with T1D delivered via a mobile-friendly Web app called Type 1 Doing Well.

Methods

Ten adolescent-parent dyads and 5 diabetes care providers participated in a series of qualitative interviews to inform the design of the app. The 3- to 4-month pilot intervention will involve 82 parents receiving daily prompts to use the app, in which they will mark the diabetes-related strength behaviors (ie, positive attitudes or behaviors related to living with or managing T1D) their teen engaged in that day. Parents will also receive training on how to observe diabetes strengths and how to offer teen-friendly praise via the app. Each week, the app will generate a summary of the teen’s most frequent strengths from the previous week based on parent reports, and parents will be encouraged to praise their teen either in person or from a library of reinforcing text messages (short message service, SMS).

Results

The major outcomes of this pilot study will include intervention feasibility and satisfaction data. Clinical and behavioral outcomes will include glycemic control, regimen adherence, family relationships and conflict, diabetes burden, and health-related quality of life.

Conclusions

This strengths-based, mobile health (mHealth) intervention aims to help parents increase their awareness of and efforts to support their adolescents’ engagement in positive diabetes-related behaviors. If efficacious, this intervention has the potential to reduce the risk of family conflict, enhance collaborative family teamwork, and ultimately improve diabetes outcomes.
