Association of SGLT-2 Inhibitors With Treatment Satisfaction and Diabetes-Specific and General Health Status in Adults With Cardiovascular Disease and Type 2 Diabetes.

Background It is unknown if initiation of a sodium-glucose cotransporter-2 inhibitor (SGLT-2i) is associated with changes in patient-reported health status outside of clinical trials. Methods and Results Using a prospective observational study design, adults with type 2 diabetes and cardiovascular disease were recruited from 14 US hospitals between November 2019 and December 2021 if they were new users of noninsulin antidiabetic medications. The primary outcome was change in 6-month diabetes treatment satisfaction. Secondary outcomes included diabetes-related symptom distress, diabetes-specific quality of life, and general health status for all patients and based on cardiovascular disease type. Inverse probability of treatment weight using propensity score was performed to compare outcome changes based on medication use. Of 887 patients (SGLT-2i: n=242) included in the inverse probability of treatment weight analyses, there was no difference in changes in treatment satisfaction in SGLT-2i users compared with other diabetes medication users (0.99 [95% CI, -0.14 to 2.13] versus 1.54 [1.08 to 2.00], P=0.38). Initiating an SGLT-2i versus other diabetes medications was associated with a greater reduction in ophthalmological symptoms (-3.09 [95% CI, -4.99 to -1.18] versus -0.38 [-1.54 to 0.77], P=0.018) but less improvement in hyperglycemia (1.08 [-2.63 to 4.79] versus -3.60 [-5.34 to -1.86], P=0.026). In subgroup analyses by cardiovascular disease type, SGLT-2i use was associated with a greater reduction in total diabetes symptom burden and neurological sensory symptoms in patients with heart failure. Conclusions Among patients with type 2 diabetes and cardiovascular disease, initiating an SGLT-2i was not associated with changes in diabetes treatment satisfaction, total diabetes symptoms, diabetes-specific quality of life, or general health status.

A middle range theory of self- and family management of chronic illness.

BACKGROUND: The Self- and Family Management Framework was created in 2006 to help structure self- and family management science. Based on a series of reviews and syntheses of emerging research and critical evaluation, we developed the Framework into a robust nursing theory. PURPOSE: In this article, we reintroduce the Self- and Family Management Framework as the Middle Range Theory of Self- and Family Management of Chronic Illness. METHODS: We review steps in the development and updating of the Framework, share rationale for advancement to a middle range theory, explicate components of the newly designed model, and propose future directions. DISCUSSION AND CONCLUSION: It is our hope that this middle range theory will guide researchers and clinicians more comprehensively in supporting patients and families managing chronic illness, which will in turn inform continued theory development.

Self-Management and Glycemic Targets in Adult Haitian Immigrants With Type 2 Diabetes: Research Protocol.

BACKGROUND: Type 2 diabetes (T2D) is a chronic condition affecting more than 34.2 million U.S. adults, and people of African descent have a disproportionate burden. Haitian immigrants' unique cultural and biological factors put them at elevated risk for T2D-related complications. Despite prior research highlighting the success of multimethod approaches to T2D self-management behaviors on glycemic targets, a dearth of studies have used these methods to improve diabetes self-management in this marginalized population. OBJECTIVES: This article describes a repeated-measures design protocol of a going study about self-management behaviors among adult Haitian immigrants with T2D and characterizing their barriers to T2D self-management. METHODS: We will enroll 100 Haitian immigrants aged 18-64 years who have lived with T2D for at least 1 year. Using multiple recruitment methods and Research Electronic Data Capture, subjective and objective data on T2D self-management practices, glucose variability via continuous glucose monitor, and a comprehensive view of physical activity via actigraphy are collected. RESULTS: Data analysis will follow a two-part approach mirroring the two primary study objectives. DISCUSSION: Findings from the study will guide the development and testing of a culturally tailored diabetes self-management education program that will contribute essential information about best practices for this population and break barriers that may impede research on unique individuals and subsequent effective self-management.

Cognitive Behavioral Sleep Self-Management Intervention for Young Adults With Type 1 Diabetes (NCT04975230).

The purpose of this study was to explore perceptions of the first dose of a cognitive behavioral sleep self-management intervention (CB-sleep) among young adults aged 18 to 25 years with type 1 diabetes (T1D). We used a qualitative descriptive approach to conduct in-depth semi-structured focused interviews with a purposive sample of 16 young adults with T1D, transitioning from adolescence to early adulthood. Interviews were audio-recorded, transcribed verbatim, and analyzed using qualitative content analysis. Participants described their sleep knowledge (previous, new, and additional), sleep health goals, along with barriers and facilitators of the CB-sleep intervention. Based on these results, we suggest CB-sleep is a useful modality with the potential to support sleep self-management in young adults with T1D during this complex life transition. Furthermore, CB-sleep could be incorporated into an existing diabetes self-management education and support program after pilot testing and determining efficacy to improve sleep and glycemic health.

Use of the Self- and Family Management Framework in quantitative studies.

BACKGROUND: The Self- and Family Management Framework (SFMF) identifies factors and outcomes of patient and family management of chronic illness. In a previous citation analysis, we reported the frequency and nature of use of the SFMF. PURPOSE: We conducted a sub-analysis of quantitative articles in the citation analysis to examine testing of relationships depicted in the SFMF. METHODS: We analyzed study purposes, independent and dependent variables, study implications, and text that referred to the SFMF in 40 articles. FINDINGS: The SFMF has been used largely to explore factors affecting SFM behaviors, focusing on patient versus family self-management. Independent variables included all categories of facilitators/barriers specified in the SFMF. Dependent variables included all SFMF components (Facilitators/Barriers, Processes, Proximal and Distal Outcomes). Racial/ethnic diversity was limited among study participants. Study implications pertained mostly to psychosocial outcomes. Most studies referred to the SFMF generally. DISCUSSION: Findings will contribute to revision of the SFMF.

Objective Sleep-Wake Characteristics Are Associated With Diabetes Symptoms in Young Adults With Type 1 Diabetes.

PURPOSE: The primary purpose of this descriptive cross-sectional study was to examine the associations between sleep-wake characteristics (total sleep time, sleep variability, sleep onset latency, and sleep efficiency), distress symptoms (general and diabetes), and diabetes physical symptoms in young adults ages 18 to 30 years with type 1 diabetes (T1D). The secondary purpose was to determine whether biological sex, body mass index (BMI), and T1D duration (covariates) influence the relationships among the study variables. METHODS: Forty-six young adults with T1D, recruited from diabetes clinics from December 2018 to February 2020, wore a wrist actigraph and continuous glucose monitor concurrently for 6 to 14 days and completed the PROMIS Emotional Distress Scale, Diabetes Distress Scale, and Diabetes Symptom Checklist-Revised. RESULTS: Shorter total sleep time and poorer sleep efficiency were associated with higher diabetes emotional distress symptoms. Higher sleep variability was associated with higher neurological pain symptoms. A longer sleep onset latency was associated with higher symptoms of diabetes distress, including psychological, cognitive, hyperglycemia, and a higher total symptom burden. Associations remained statistically significant after adjusting for biological sex and BMI, with the exception of sleep onset latency and total symptom burden. CONCLUSIONS: Poorer objective sleep-wake characteristics were associated with higher diabetes symptoms even after considering biological sex and BMI among young adults with T1D.

Glucose and unstructured physical activity coupling during sleep and wake in young adults with type 1 diabetes.

Glucose variations have a bidirectional relationship with the sleep/wake and circadian systems in type 1 diabetes (T1D); however, the mechanisms remain unclear. The aim of this study was to describe the coupling between glucose and unstructured physical activity over 168 h in young adults with T1D. We hypothesized that there would be differences in sleep and wake characteristics and circadian variations. Glucose was measured with a continuous glucose monitoring device every 5 min and activity with a non-dominant wrist-worn actigraph in 30-s epochs over 6-14 days. There was substantial glucose and unstructured physical activity coupling during sleep and wake, along with circadian variation based on the wavelet coherence analysis. The extent to which glucose fluctuations result in disrupted sleep over longer than one week should be examined considering the harmful effects on achieving glycemic targets. Further studies are needed to delineate the respective roles of glucose production and utilization and the potential for improved meal and insulin timing to optimize glucose and sleep in this population reliant on exogenous insulin.

Variations in Sleep Characteristics and Glucose Regulation in Young Adults With Type 1 Diabetes.

CONTEXT: Short sleep duration and sleep disruptions are associated with impaired glucoregulation in type 1 diabetes (T1D). However, the mechanistic pathways between sleep and glucose variability remain unclear. OBJECTIVE: To determine within- and between-person associations between objective sleep-wake characteristics and glucose variability indices. METHODS: Multilevel models were used to analyze concurrent sleep and glucose patterns over 7 days in 42 young adults with T1D in their natural home environment. Young adults with T1D (mean age 22.2 ± 3.0 years, HbA1c 7.2%, 32.6% male) for at least 6 months with no other medical or major psychiatric comorbidity were included. Sleep-wake characteristics were measured via wrist actigraphy and glucose variability indices via a continuous glucose monitor (CGM). RESULTS: Lower sleep efficiency predicted higher glucose variability (less time in range ß = 0.011 and more time in hyperglycemia ß = -0.011) within-person. A longer wake after sleep onset and more sleep disruptions were associated with higher glucose variability between persons (ß = 0.28 and 0.31). Higher glucose variability predicted poorer sleep within-person (delayed bedtime, waketime, mid-sleep time, and lower sleep efficiency), while higher glucose variability was associated with poorer sleep and more sleep disruptions between persons (lower sleep efficiency, longer wake after sleep onset, and a higher sleep fragmentation index). CONCLUSION: Clinicians can address the reciprocal nature of the sleep-glucose relationship by optimizing sleep and targeting efforts toward a euglycemic range overnight. Sleep habits are a modifiable personal target in diabetes care.

Youth and Parent Perspectives on the Acceptability of a Group Physical Activity and Coping Intervention for Adolescents With Type 1 Diabetes.

PURPOSE: To examine youth and parent perspectives on the acceptability of Bright 1 Bodies, a group physical activity and coping intervention for adolescents with type 1 diabetes mellitus (T1DM). METHODS: Adolescents participated in 12 weekly sessions of moderate to vigorous physical activity and discussion with peers with T1DM. Adolescents completed an exit survey measuring satisfaction with the intervention on a 5-point Likert scale. Semistructured interviews were conducted with adolescents and at least one parent. Qualitative description was used to develop themes that summarize the acceptability of the intervention. RESULTS: Mean scores for survey subscales were: 4.5 (SD = 0.39) for program components and strategies, 4.4 (SD = 0.44) for comfort with the intervention, and 4.3 (SD = 0.62) for instructors. Themes included: (1) adolescents and parents valued being around others with T1DM and their families, (2) the intervention helped adolescents gain knowledge and reinforce diabetes self-management behaviors, (3) challenges included convenience and sustaining participant engagement, and (4) adolescents intended to sustain physical activity and diabetes self-management behaviors after the intervention. CONCLUSIONS: Adolescents and parents viewed the intervention as acceptable across multiple domains. Participants valued the group aspect of the intervention, and future interventions would benefit from integrating social interactions with others with T1DM.

Exploring Sleep Health in Young Adults with Type 1 Diabetes.

The purpose of this qualitative descriptive study was to describe the sleep health goals in 35 young adults age 18-30 years with type 1 diabetes (T1D). We reviewed clinician sleep reports generated from wrist-worn actigraphs with participants during an in-depth semistructured telephone interview. Interviews were audio-recorded then transcribed verbatim. We performed a constant comparison method for content analysis using NVivoTM. The following two overarching health goals are identified: (a) promoting sleep (quantity, quality, hygiene, bedtime/waketime) and (b) improving diabetes self-management (time in range, sleep and glucose monitoring, and diet). Young adults in the study readily generated goals after visualizing their sleep reports. Sleep data visualization and debriefing is an effective strategy to elicit health goals for young adults with T1D. Supporting young adults with T1D to achieve their health goals for sleep promotion and diabetes self-management is a promising direction for improved sleep and consequently the attainment of glycemic targets.

Expect the unexpected: Adolescent and pre-teens' experience of diabetes technology self-management.

OBJECTIVE: Only 17% of adolescents with type 1 diabetes (T1D) are currently meeting their glycemic targets despite advances in diabetes technologies. Self-management behaviors and challenges specific to use of diabetes technologies are insufficiently studied in adolescents. We aimed to describe the experience of diabetes technology self-management, including facilitators and barriers, among preteens/adolescents with low and high A1C. RESEARCH DESIGN AND METHODS: Youth (10-18 years of age) with T1D who use insulin pump therapy were recruited from the larger quantitative cohort of a mixed methods study for participation in semi-structured qualitative interviews. Maximum variability sampling was used to recruit youth with A1C <7.5% (n = 5) and A1C >9% (n = 5). Participants' personal insulin pump and continuous glucose monitoring data were downloaded and served as a visual reference. Interviews were analyzed using a qualitative descriptive approach. RESULTS: Participants were 50% female with a median age of 14.9 years and 80% used CGM. The sample was predominantly white (90.0%). Analysis produced four major themes, Bad Day, Expect the Unexpected, Nighttime Dependence, and Unpredictability, It's Really a Team and interconnecting subthemes. Youth characterized ''Bad Days'' as those requiring increased diabetes focus and self-management effort. The unpredictability (''Expect the Unexpected'') of glucose outcomes despite attention to self-management behaviors was considerable frustration. CONCLUSIONS: Diabetes devices such as insulin pumps are complex machines that rely heavily on individual proficiency, surveillance, and self-management behaviors to achieve clinical benefit. Our findings highlight the dynamic nature of self-management and the multitude of factors that feed youths' self-management behaviors.

Use of the self- and family management framework and implications for further development.

BACKGROUND: The Self- and Family Management Framework (SFMF) was created in 2006 and revised in 2015 to guide research on self- and family management of chronic conditions. There has been no review of use of the SFMF. PURPOSE: We reviewed articles citing the SFMF to identify the frequency and nature of use. METHOD: We conducted a citation analysis, searching Web of Science, Scopus, and Google Scholar databases and extracted key data from identified articles. FINDINGS: Of 126 articles, 84(66%) cited the 2006 SFMF, 37(29%) cited the 2015 SFMF, and 6(5%) cited both. The SFMF was used most to inform study design. Users noted strengths (e.g., considers family context) and limitations (e.g., non-specification of patient- family caregiver synergies) of the framework. DISCUSSION: The SFMF has been used broadly to guide research on self- and family management of chronic conditions. Findings will inform development of a third version of the SFMF.

Circadian characteristics of the rest-activity rhythm, executive function, and glucose fluctuations in young adults with type 1 diabetes.

Circadian alignment is an important element in individual health, and one behavioral marker, rest-activity rhythm, could influence self-management in young adults with type 1 diabetes (T1D). Little is known about the rest-activity rhythms, executive function, and glycemia among young adults with type 1 diabetes (T1D). The purpose of this study was to evaluate parametric and nonparametric circadian characteristics of the rest-activity rhythm and the associations between these variables, sleep-wake behavior, executive function, and glycemia among young adults with T1D. Young adults with T1D, recruited from diabetes clinics, wore wrist actigraphs and a continuous glucose monitor (CGM) concurrently for 6-14 days. Participants completed a 3-minute Trail Making Test on paper and electronic questionnaires - 8-item PROMIS v1.0 Emotional Distress Scale, 17-item Diabetes Distress Scale, including twice-daily Pittsburgh sleep diaries. Cosinor and nonparametric analyses were used to compute the rest-activity rhythm parameters, and linear regression modeling procedures were performed to determine the associations among the study variables. The sample included 46 young adults (mean age 22.3 ± 3.2; 32.6% male; 84.8% non-Hispanic White, HbA1c mean 7.2 ± 1.1%, BMI mean 27.0 ± 4.4 kg/m2). A number of parametric associations were observed between a stronger rhythm, better objective sleep-wake characteristics, and less daytime sleepiness. Nonparametric circadian parameters were significantly associated with several outcomes: a stronger rhythm adherence (higher inter-daily stability) with better objective sleep-wake characteristics, better executive function, lower diabetes distress, less hyperglycemia risk, and more time spent in hypoglycemia/hypoglycemia risk; and a more robust rhythm (higher relative amplitude) with better objective sleep-wake characteristics and more time spent in hypoglycemia/higher hypoglycemia risk. Future work should be directed at designs that test causality, such as interventions directed at the strength and stability of rest-activity rhythms, for the potential to improve glucoregulation and other diabetes outcomes.

Sleep-wake characteristics, daytime sleepiness, and glycemia in young adults with type 1 diabetes.

STUDY OBJECTIVES: The purpose of this study was to describe objective sleep-wake characteristics and glycemia over 7-14 days in young adults with type 1 diabetes. In addition, person-level associations among objective sleep-wake characteristics (total sleep time, sleep variability, and sleep fragmentation index), daytime sleepiness, and glycemia (glycemic control and glucose variability) were examined. METHODS: In this cross-sectional study, objective sleep-wake characteristics were measured via actigraphy and glucose variability via continuous glucose monitoring over 6-14 days. At baseline, participants completed the Psychomotor Vigilance Test, the Trail Making Test, and questionnaires on daytime sleepiness, sleep quality, and sleep disturbance including sleep diaries. RESULTS: Forty-six participants (mean age, 22.3 ± 3.2 years) wore a wrist actigraph and underwent continuous glucose monitoring concurrently for 6-14 days. Greater sleep variability was directly associated with greater glucose variability (mean of daily differences; r = .33, P = .036). Higher daytime sleepiness was directly associated with greater glucose variability (mean of daily differences; r = .50, P = .001). The association between sleep variability and glucose variability (mean of daily differences) was no longer significant when accounting for daytime sleepiness and controlling for type 1 diabetes duration (P > .05). A higher sleep fragmentation index was associated with greater glucose variability (B = 1.27, P = .010, pr2 = 0.40) after controlling for type 1 diabetes duration and accounting for higher daytime sleepiness. CONCLUSIONS: Sleep-wake variability, sleep fragmentation, daytime sleepiness, and the associations with glycemia are new dimensions to consider in young adults with type 1 diabetes. Sleep habits in this population may explain higher glucose variability, and optimizing sleep may improve overall diabetes management.

Factors associated with diabetes distress among adolescents with type 1 diabetes.

AIMS: To describe the specific domains of diabetes distress and factors associated with these domains. BACKGROUND: Diabetes distress is a common problem but not well recognised in adolescents by healthcare providers or adolescents themselves. There is insufficient evidence on how specific domains of diabetes distress exist in adolescents, making it challenging to select precise components to alleviate diabetes stress. DESIGN: A quantitative, descriptive and cross-sectional study. METHODS: Data were collected on socio-demographic and clinical characteristics, diabetes distress, perceived stress, self-efficacy and diabetes self-management using established questionnaires. Multivariate linear regression was conducted to examine the associations between specific factors and four domains in diabetes distress. STROBE checklist was used as the guideline for this study. RESULTS: A total of 100 adolescents with type 1 diabetes aged 12 to 18 years participated in this study. Adolescents experienced the highest levels of distress in the regimen-related distress [2.41 (SD =0.82)] and physician-related distress [2.40 (SD =0.80)] domains. Older age, female gender, more diabetes problem-solving and higher levels of perceived stress were associated with higher regimen-related distress (ß = 0.21 ~ 0.45, p < 0.05). Older age, female gender, a lower degree of endorsement of relevant diabetes-related goals and higher levels of perceived stress were associated with higher physician-related distress (ß = -0.29 ~ 0.34, p < 0.05). CONCLUSIONS: Diabetes distress was reported more on regimen-related and physician-related domains among adolescents with type 1 diabetes in China, associating with older age, female, increased perceived stress and poor diabetes-related problem-solving. RELEVANCE TO CLINICAL PRACTICE: Nurses need to screen the specific domains of diabetes distress among adolescents with type 1 diabetes, especially for the older adolescents and girls. This study highlighted the importance of incorporating diabetes-related problem-solving support and stress management strategies into diabetes management for adolescents with type 1 diabetes, which could help relieve diabetes distress.

Parent-Child Relationship Quality as a Mediator of the Association between Perceived Stress and Diabetes Self-Management in Adolescents With Type 1 Diabetes.

Diabetes self-management is suboptimal in adolescents with type 1 diabetes (T1D), including those in China. The aim of the study was to investigate the impact of parent-child relationship quality on diabetes self-management. Data were collected by a self-report survey among 122 Chinese adolescents from April to July 2017. The data were analyzed using a one-way analysis of variance, descriptive analyses, correlation analyses, and mediation analyses. The mean age was 13.8 (range, 10-18) years, and the mean diabetes duration was 4.1 (±3.1) years. About half of the adolescents with T1D experienced high levels of perceived stress. Parent-child relationship quality mediated the associations between perceived stress and collaboration with parents, diabetes care activities, and diabetes communication on aspects of diabetes self-management (ps < 0.05). To reduce the negative impacts of perceived stress on diabetes self-management in this population, parent-child relationship quality should be considered an important element of family-based interventions and clinical practice.

Self-management among pre-teen and adolescent diabetes device users.

OBJECTIVE: Despite increased diabetes device use, few adolescents with type 1 diabetes (T1D) meet glycemic targets. We examine associations between utilization of insulin pumps and continuous glucose monitoring (CGM) and glycemic control. RESEARCH DESIGN AND METHODS: This prospective cohort study included 80 youths (10-18 years of age) with T1D. Multiple linear regression and linear mixed models (LMM) were used to estimate the effects of device self-management on HbA1c and daily time in range (70-180 mg/dL), respectively. RESULTS: Every blood glucose (BG) input/day was associated with a 0.2% decrease in HbA1c (95% CI: -0.297, -0.013), each bolus/day was associated with a 0.2% decrease (-0.327, -0.057), and use of CGM was associated with a 0.5% decrease (-1.00, -0.075). Among CGM users (n = 45) every 10% increase in CGM use was associated with a 0.3% decrease in HbA1c (-0.390, -0.180). In LMM accounting for within subject and between subject variability, there was a negative association between BG input/day frequency (coefficient = -1.880, [-2.640, -1.117]) and time in range. Residual random effects for CGM users were large showing time in range varied between youth with a SD of 15.0% (3 hours and 36 minutes) (SE 2.029, [11.484, 19.530]). Time in range varied significantly from day-to-day with SD of 18.6% (4 hours and 40 minutes) (SE0.455, [17.690, 19.473]). CONCLUSIONS: Device self-management behaviors among youth are significantly associated with both HbA1c and time in range. Our findings showing an association between reduced time in range and increased self-management behaviors is novel and deserves further investigation.

Daily variations in sleep and glucose in adolescents with type 1 diabetes.

OBJECTIVE: We used multilevel models (MLMs) to determine person (between-persons) and day level (within-person) associations between glucose variability indices and sleep characteristics in adolescents with type 1 diabetes (T1D). METHODS: Adolescents with T1D (Mean age 13.4 ± 1.8 years; 37.8% male; mean HbA1c 8.2 ± 1.2%, 66 mmol/mol) monitored their sleep and glucose patterns concurrently for 3-7 days with a wrist actigraph on their non-dominant wrist and a continuous glucose monitor (CGM) (their own or a provided, blinded CGM). Glucose variability indices included J index, coefficient of variation, low and high blood glucose risk indices (LBGI and HBGI), time in range, and sleep characteristics, including bedtime, wake time, total sleep time, sleep efficiency, wake after sleep onset, awakenings, and sleep fragmentation index. RESULTS: More overall glucose variability was associated within person, more sleep disruptions (more awakenings and more fragmentation) or poorer sleep in our study (earlier wake time or longer wake after sleep onset). Also, more time spent in hypoglycemia <70 mg/dL and a higher LBGI was associated within person with earlier wake time indicating poorer sleep. However, a lower LBGI was associated with a later between-persons wake time. CONCLUSIONS: Monitoring over a longer period of time in subsequent studies would allow researchers to determine the within person association between habitual short sleep duration and glucose variability. Providers should regularly assess sleep habits in adolescents as a way to improve glycemic control. Targeting a euglycemic range overnight is also important to promote better sleep and to decrease sleep disruptions.

A systematic review and meta-analysis of behavioral sleep interventions for adolescents and emerging adults.

In the United States, more than two-thirds of adolescents and one-third of emerging adults report habitual short sleep duration, which is a known risk factor for psychological distress. The primary aim of this systematic review and meta-analysis was to evaluate the effect of behavioral sleep-promoting interventions on the sleep characteristics (e.g., total sleep time and sleep efficiency) of adolescents and emerging adults (aged 12-25 y) who do not have a sleep disorder. The secondary aim was to determine the effect of behavioral sleep-promoting interventions on psychological distress. Multiple electronic databases were searched for relevant randomized controlled trials (RCTs) published in English. Fourteen RCTs were included in the qualitative synthesis (N = 932), seven were included in the meta-analysis (n = 711) to address the primary aim, and three (n = 253) were included to address the secondary aim. The pooled standardized mean difference for sleep-promoting interventions after treatment for total sleep time was 34.92 min (95% CI: 8.70, 61.14). Sleep-promoting interventions had no significant effect on sleep efficiency. More RCTs that involve adolescents and emerging adults are needed to determine the effect of sleep-promoting interventions on reducing psychological distress in this high-risk age group.

Sleep, self-management, neurocognitive function, and glycemia in emerging adults with Type 1 diabetes mellitus: A research protocol.

Type 1 Diabetes (T1D) affects 1.6 million Americans, and only 14% of emerging adults ages 18-25 years achieve targets for glycemic control (A1C < 7.0%). Sleep deficiency, including habitual short sleep duration (<6.5 hr total sleep time and high within-person variability in total sleep time), is associated with poorer glycemic control. Emerging adults with T1D have a more pronounced sleep extension on weekends compared with matched controls, consistent with sleep deficiency; however, associations among sleep variability and glycemic control have not been explored in this population. Sleep deficiency may affect the complex higher-order neurocognitive functioning needed for successful diabetes self-management (DSM). We report the protocol for an ongoing study designed to characterize sleep and the associations among sleep deficiency, neurocognitive function, DSM, diabetes quality of life, and glycemia among a sample of 40 emerging adults with T1D. We monitor sleep via wrist-worn actigraphy and glucose via continuous glucose monitoring concurrently over 14 days. We are collecting data on self-report and objective sleep, a 10-min psychomotor vigilance test on a PVT-192 device, a 3-min Trail Making Test on paper, and questionnaires, including twice-daily Pittsburgh sleep diaries using Research Electronic Data Capture (REDCap)TM . Results from this study will be used to support the development and testing of the efficacy of a tailored sleep self-management intervention that may improve total sleep time, sleep variability, neurocognitive function, DSM, glycemic control, and glucose variability among emerging adults with T1D.
