Associations Between Objective Sleep Behaviors and Blood Glucose Variability in Young Children With Type 1 Diabetes.

BACKGROUND: Young children with Type 1 diabetes (T1D) are at risk for extreme blood glucose variability, a risk factor for suboptimal glycated hemoglobin A1c (HbA1c) and long-term health complications. We know that a reciprocal relationship exists between sleep and glycemic outcomes in older youth with T1D; however, little research has examined objective sleep in young children (<7 years) with T1D. PURPOSE: This study examines bidirectional associations between sleep behaviors and glycemic variability in young children with T1D. METHODS: Thirty-nine young children with T1D (Mage 4.33 ± 1.46 years; MHbA1c 8.10 ± 1.06%) provided accelerometry data to objectively measure sleep onset latency, number of nighttime awakenings, and total sleep time. We also assessed HbA1c, average blood glucose, and glycemic variability (i.e., standard deviation of blood glucose from device downloads). We evaluated bidirectional relationships using multilevel modeling in SAS, with weekday/weekend as a Level 2 moderator. RESULTS: Children averaged 8.5 ± 1.44 hr of sleep per night, but only 12.8% met current sleep recommendations. Children experienced more nighttime awakenings, higher blood glucose, and more glycemic variability on weekends. Sleep onset latency and nighttime awakenings predicted greater glycemic variability on weekends, and weekend glycemic variability predicted increased nighttime awakenings. CONCLUSIONS: Most young children with T1D did not meet sleep recommendations. Young children experienced more nighttime awakenings, higher blood glucose, and increased glycemic variability on weekends only, when routines may be less predictable. Findings suggest that one way families of young children with T1D may be able to decrease glycemic variability is to keep consistent routines on weekdays and weekends.

Parent Perspectives on Educational and Psychosocial Intervention for Recent-Onset Type 1 Diabetes in Their School-Age Child: A Qualitative Study.

OBJECTIVE: The recent-onset period of type 1 diabetes (T1D) in early school-age children should include comprehensive, parent-focused T1D education as well as family-centered resources and support to help with adjustment. Here, we present parent/caregiver perspectives on specific areas of concern during the recent-onset period of T1D and their preferred timing for different topics related to T1D education. METHODS: Parents/caregivers of 5- to 9-year-old children with T1D completed a card-sorting task and qualitative interview to describe ongoing areas of concern and preferred educational topics during the first year after T1D diagnosis. RESULTS: Thirteen parents/caregivers (aged 35.1 ± 6.9 years) of a child with T1D (aged 8.9 ± 0.8 years, 11.3 ± 7.0 months post-diagnosis) completed the card-sorting task, and 11 completed the qualitative interview. Parents/caregivers endorsed four preferred stages of education: basic education and T1D survival skills during month 1 post-diagnosis, application and practice of T1D skills from months 1-3, access to community supports to cope with anxiety and distress from months 3-6, and support to build autonomy and manage burnout beyond month 6 post-diagnosis. Parents/caregivers endorsed four main themes for ongoing concerns: anxiety, autonomy, distress, and support. CONCLUSION: Parents endorsed four time points for education and psychosocial services within the first year of a T1D diagnosis. Parents/caregivers may benefit the most from psychosocial interventions 3-6 months post-diagnosis, once they have had sufficient time to develop basic T1D management skills. These findings support the need for regular parent psychosocial screening and access to scalable psychosocial interventions in the first year post-diagnosis of T1D.

Intervention to reduce hypoglycemia fear in parents of young kids using video-based telehealth (REDCHiP).

OBJECTIVE: To evaluate the efficacy of a new video-based telehealth intervention to reduce hypoglycemia fear in parents of young children with type 1 diabetes. METHODS: We randomized 42 parents to either immediate treatment (reducing emotional distress for childhood hypoglycemia in parents, REDCHiP; n = 22) or a waitlist control (WAITLIST; n = 21) condition. REDCHiP parents completed a 10-session video-based telehealth intervention, while WAITLIST parents continued in usual care. After 14-weeks, WAITLIST parents completed the telehealth treatment. We examined for between group changes in parental hypoglycemia fear and parenting stress (n = 18 per condition), 3-month maintenance of treatment effects for parents randomized to REDCHiP (n = 15), and pre-post changes for the entire sample (n = 36). RESULTS: Mostly mothers participated (97.6%). They reported a mean age of 35.2 ± 5.0 years at pre-treatment. Children were 4.4 ± 1.4 years old and 59.5% boys. Between group comparisons showed a significant reduction in hypoglycemia fear (P = .04) and a trend toward reduction in parenting stress-frequency (P = .092) for REDCHiP parents compared to WAITLIST parents. After the three-month maintenance period, REDCHiP parents reported significant reductions in hypoglycemia fear, parenting stress-frequency, and parenting stress-difficulty (P's < .01) compared to pre-treatment. When all parents received the telehealth treatment, we also observed significant reductions in hypoglycemia fear, parenting stress-frequency, and parenting stress-difficulty (P's < .001), and sensitivity analyses revealed a significant reduction in child glycated hemoglobin for children who entered the treatment above target (P < .05). CONCLUSION: Our new video-based telehealth intervention appears to reduce hypoglycemia fear and parenting stress and may help parents of very young children with T1D to better achieve optimal child glycemic control when children are above target.

Implementing clinic-wide depression screening for pediatric diabetes: An initiative to improve healthcare processes.

OBJECTIVE: Youth with type 1 diabetes (T1D) endorse high rates of depressive symptoms, which can significantly impair self-management, glycemic control, and quality of life. Current guidelines recommend annual depression screening for all adolescents with T1D, but few models exist to implement screening procedures across clinics in this population. The primary aim of this project was to increase depression screening from 0% to 80% in four clinics, and to describe the structured quality improvement process to reach this goal. METHODS: All patients aged 12 to 21 years old with T1D at four participating clinics in a Midwestern hospital system were eligible to participate. Using a two-stage process, patients were administered the Patient Health Questionnaire (PHQ-2 plus PHQ-9 if positive) annually. Rates of depression screening by clinic site, rates of positive depression screens, social worker documentation of follow-up care, and associations with diabetes-related health outcomes were analyzed. RESULTS: Over 2 years, average depression screening rates increased from 0% to 75% across all clinics, and 89% of patients with a positive screen met with a social worker for a targeted mental health assessment. At initial screening, 7.6% of patients screened positive for at-risk depressive symptoms on the PHQ-2 and from that group, 6.7% additionally screened positive on the PHQ-9. CONCLUSIONS: Annual depression screenings were feasibly implemented across four clinics and the use of real-time data listening and automated processes facilitated successful implementation. Future directions include further automation, targeted training and billing mechanisms, dissemination to non-metropolitan clinics, and further assessment of depression screening tools for adolescents with T1D.

Hope and mealtime insulin boluses are associated with depressive symptoms and glycemic control in youth with type 1 diabetes mellitus.

Adherence to treatment regimen is associated with improved glycemic control and is particularly problematic during adolescence for those with type 1 diabetes mellitus (T1DM). Both glycemic control and adherence may be negatively impacted by poor psychological outcomes in adolescence, such as depressive symptoms and low hopefulness. The purpose of this study was to examine associations between the mealtime insulin bolus score (BOLUS), a more robust proxy measure of adherence than frequency of blood glucose monitoring or self-report, with depressive symptoms, hope, and hemoglobin A1c (HbA1c). Ninety adolescents completed measures of hope (Children's Hope Scale) and depressive symptoms (Center for Epidemiologic Studies-Depression Scale), as well as lab-based measures of HbA1c and mealtime insulin bolus scores (BOLUS). Higher levels of hope were associated with lower levels of depressive symptoms, more frequent mealtime insulin boluses, and better glycemic control. Higher levels of BOLUS behavior were associated with lower depressive symptoms and better glycemic control. Both BOLUS behavior and hope independently and significantly impacted the relationship between depressive symptoms and HbA1c, suggesting a possible mediation. Since hope and BOLUS were each associated with the relationship between depressive symptoms and glycemic control, following confirmation of this relationship in a longitudinal study, clinics may consider measuring hope and BOLUS among youth with high depressive symptoms and further investigating BOLUS behavior and hope as potential intervention targets to improve glycemic control.

Shared Responsibility for Type 1 Diabetes Care Is Associated With Glycemic Variability and Risk of Glycemic Excursions in Youth.

Objective: We examined how parent and youth responsibility for type 1 diabetes (T1D) care is related to adherence and glycemic outcomes, namely, glycemic variability and risk of glycemic excursions. Methods: One hundred thirty-five parent-youth dyads (10-16 years old; diagnosed with T1D for at least 6 months) participated in this study. Percent responsibility of T1D care attributed to the youth, parent, or shared was measured using the Diabetes Family Responsibility Questionnaire. We collected youth's hemoglobin A1c (HbA1c) and glucometer downloads to examine relationships between responsibility and HbA1c, frequency of blood glucose monitoring (self-monitoring blood glucose, SMBG), risk of glycemic excursions, and actual glycemic variability using bivariate correlations and path analysis. Results: Participants reported shared responsibility for almost half of T1D self-care tasks. Bivariate correlations showed shared responsibility was associated with less variability, whereas parent responsibility was associated with greater glycemic variability and risk for glycemic excursions. Youth responsibility was associated with lower frequency of SMBG. The path analyses confirmed our correlational findings (ps<.05) and better characterized interactions with age for youth-reported responsibility. Conclusions: Our results support the hypothesis that shared T1D responsibility is associated with better diabetes outcomes in youth.

The Influence of Neighborhood Crime on Increases in Physical Activity during a Pilot Physical Activity Intervention in Children.

The purpose of this study was to examine whether neighborhood crime moderated the response (increases in steps) to a pilot intervention to increase physical activity in children. Twenty-seven insufficiently active children aged 6-10 years (mean age = 8.7 years; 56 % female; 59 % African American) were randomly assigned to an intensive intervention group (IIG) or minimal intervention group (MIG). Change in average daily number of steps from baseline was regressed against an index of neighborhood crime in a multilevel repeated-measures model that included a propensity score to reduce confounding. Safer neighborhoods were associated with higher increases in steps during the pilot intervention (interaction p = 0.008). Children in the IIG living in low-crime neighborhoods significantly increased their physical activity (5275 ± 1040 steps/day) while those living in high-crime neighborhoods did not (1118 ± 1007) (p for difference = 0.046). In the IIG, the increase in daily steps was highly correlated with neighborhood crime (r = 0.58, p = 0.04). These findings suggest the need for physical activity interventions to account for participants' environments in their design and/or delivery. To promote healthy behaviors in less-supportive environments, future studies should seek to understand how environments modify intervention response and to identify mediators of the relationship between environment and intervention.

A Nonrandomized Pilot of a Group, Video-Based Telehealth Intervention to Reduce Diabetes Distress in Parents of Youth With Type 1 Diabetes Mellitus.

OBJECTIVES: Our aim in this study was to refine and pilot a video-based telehealth intervention to reduce diabetes distress, depressive symptoms and hypoglycemia fear in parents of school-age children with type 1 diabetes and to assess for changes in child glycated hemoglobin (A1C). METHODS: We recruited 41 parents of children (5 to 12 years) to participate in a manualized, video-based telehealth intervention (Cognitive Adaptions to Reduce Emotional Stress [CARES]). Of these, 29 parents completed either a 12-week (n=13) or 8-week (n=16) version of CARES based on the timing of their recruitment. We assessed feasibility (i.e. attrition, attendance) and parent satisfaction with CARES. We used repeated-measures analysis of variance with parent group (8 vs 12 sessions) as a between-subject variable and time as a within-subject variable to measure change in our dependent variables. RESULTS: Mostly mothers participated (97.3%). Parents' mean age was 39.65±6.84 years and children's mean age was 9.86±1.57 years at pretreatment. CARES had low attrition (20% to 25%) and good attendance (96% to 98%). Parents also reported high levels of treatment satisfaction (>85%). There were significant main effects for time for parent-reported diabetes distress and depressive symptoms at posttreatment and 3-month follow-up. There was a statistical trend suggesting a time × group interaction for parent depressive symptoms at posttreatment. There was a significant main effect for time for hypoglycemia fear at the 3-month follow-up but no change at posttreatment. There was no change in child A1C at posttreatment. CONCLUSION: CARES showed high parent satisfaction, good feasibility and promising results for reducing diabetes distress in parents of school-age children with type 1 diabetes.

Adjusted Cutoff Scores Increase Sensitivity of Depression Screening Measures in Adolescents With Type 1 Diabetes.

OBJECTIVE: To measure the acceptability and diagnostic accuracy of commonly used depression screening measures to determine ideal cutoff scores that sensitively identify depressive disorders in adolescents with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: One hundred adolescents (12-17 years old) completed a reference standard, semistructured diagnostic interview and both long and short versions of five commonly used depression screening measures in the United States. To assess feasibility and acceptability, we used screener completion time and participant ratings, respectively. We used descriptive statistics, area under the receiver operating characteristic (ROC) curve analyses, and paired-sample area differences under the ROC curve to assess each measure's diagnostic validity against our reference standard and to determine ideal cutoff scores for this sample. RESULTS: Adolescents had a mean age of 15.0 ± 1.7 years, time since T1D diagnosis of 6.0 ± 4.1 years, and glycated hemoglobin (HbA1c) of 8.9 ± 1.8%. Sixty percent of adolescents were male, 15% endorsed a current depressive disorder, and 15% endorsed lifetime suicidality. Measures demonstrated low sensitivity (0.33-0.67) to detect current depressive disorders using preexisting cutoff scores. However, adjusted cutoff scores increased sensitivity and reduced false negatives. All depression screening measures demonstrated "good" to "excellent" predictive validity, and the Children's Depression Inventory-2 Short version demonstrated significantly greater diagnostic accuracy than the Patient Health Questionnare-2 item version for adolescents. CONCLUSIONS: Clinics should consider using screening measures with the greatest diagnostic accuracy as identified in this study and adjusting measure cutoff scores to increase sensitivity and reduce false negatives.

Reducing Emotional Distress for Childhood Hypoglycemia in Parents (REDCHiP): Protocol for a Randomized Clinical Trial to Test a Video-Based Telehealth Intervention.

BACKGROUND: Despite the introduction of new insulin analogs, insulin pumps, and continuous glucose monitoring (CGM), young children with type 1 diabetes mellitus (T1D) remain vulnerable to episodes of hypoglycemia because of their unpredictable eating and activity patterns and high degree of insulin sensitivity. Caregivers and young children living with T1D learn to fear hypoglycemia because it is uncomfortable, unpredictable, and dangerous. Up to 60% of caregivers of young children with T1D report moderate to severe levels of fear of hypoglycemia, and caregiver fear of hypoglycemia relates to lower quality of life for families and suboptimal child glycemic control. Yet, until recently, there have been no studies reporting on a targeted intervention to treat caregiver fear of hypoglycemia in families of young children. OBJECTIVE: The aim of this project is to conduct a randomized clinical trial of an innovative, video-based telehealth intervention to treat fear of hypoglycemia in caregivers of young children with T1D versus a relevant, age-appropriate attention control intervention. METHODS: We created the Reducing Emotional Distress for Childhood Hypoglycemia in Parents (REDCHiP) intervention by merging age-appropriate T1D education and behavioral parenting strategies with cognitive behavioral therapy strategies that are effective for reducing fear and promoting adaptive coping. REDCHiP uses 10 video-based telehealth sessions that are a combination of group and individual sessions. We will recruit up to 180 families of young children with T1D to participate in this clinical trial from two pediatric diabetes clinics located in the midwestern and southern United States. Once families have been enrolled, we will randomize caregivers based on child age (age 2-3 years or 4-5 years), child sex, and family CGM use to participate in the REDCHiP or attention control intervention. Families will complete 3 assessment visits that coincide with study entry, end of treatment, and 3-month posttreatment. At each assessment visit, we will collect questionnaire data from caregivers, accelerometry data from caregivers and children, CGM data from children, and a blood sample to measure glycated hemoglobin levels from children. RESULTS: Recruitment began in July 2019, and enrollment is ongoing. The first wave of intervention delivery began in December 2019. We anticipate completing enrollment in 2023. Final reporting of results will occur within 12 months of the primary completion date. CONCLUSIONS: If the REDCHiP intervention is efficacious, next steps will be to examine multiple implementation strategies to determine how best to disseminate the intervention to pediatric diabetes clinics around the world. TRIAL REGISTRATION: ClinicalTrials.gov NCT03914547; https://clinicaltrials.gov/ct2/show/NCT03914547. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): PRR1-10.2196/17877.

An Intervention to Reduce Hypoglycemia Fear in Parents of Young Kids with Type 1 Diabetes Through Video-Based Telemedicine (REDCHiP): Trial Design, Feasibility, and Acceptability.

Background: Fear of hypoglycemia (FH) is common in parents of young children with type 1 diabetes (T1D) and problematically linked to maladaptive behaviors to avoid low blood glucose, parenting stress, and burnout. This study examined the feasibility and acceptability of a novel group-based telemedicine intervention to reduce FH in parents of young children with T1D. Materials and Methods: Forty-three families of a young child with T1D (1-6 years of age; diagnosed with T1D for at least 6 months) enrolled in the study and 36 completed the Reducing Emotional Distress for Childhood Hypoglycemia in Parents (REDCHiP) intervention. We assessed intervention feasibility with rates of attrition, intervention attendance, and fidelity to the treatment manual. We assessed acceptability with treatment satisfaction surveys and qualitative interviews (from a subset of completers; n = 10) about intervention acceptability, facilitators, and challenges. Results: Study attrition was 21%, including long-term follow-up (16% before or during the treatment phase). On average, parents attended 94% of intervention sessions and fidelity to the treatment manual was 89%. Intervention completers reported high satisfaction with the treatment groups (89% average satisfaction rating). Parent-reported positive influencers of the REDCHiP intervention were increased knowledge, fear awareness, coping strategies, confidence, behavioral parenting strategies, and support, whereas intervention challenges included feeling fearful or overwhelmed, family stress, lack of trust, and difficulty connecting with other group members. Conclusions: The REDCHiP intervention demonstrated initial feasibility and acceptability. Next steps include determining the intervention's impact on objective parent and child outcomes (e.g., glycemic control, parental FH, and parental stress/distress) as well as large-scale efficacy testing.

A Time-Friendly, Feasible Measure of Nutrition Knowledge in Type 1 Diabetes: The Electronic Nutrition and Carbohydrate Counting Quiz (eNCQ).

BACKGROUND: Greater knowledge about nutrition and carbohydrate counting are associated with improved glycemic control and quality of life in youth with type 1 diabetes (T1D). However, limited assessments of nutrition and carbohydrate knowledge have been developed, and existing measures can be time-consuming, overly broad, or not conducive to routine clinical use. To fill this gap, we developed and examined the feasibility of administering the electronic Nutrition and Carbohydrate Counting Quiz (eNCQ). METHOD: Ninety-two caregivers and 70 youth with T1D (mean age 12.5 years; mean time since diagnosis 5 years; English speaking) completed the 19-item eNCQ via tablet during a routine clinical visit. Completion time and item completion rates were used to assess feasibility. Relationships between eNCQ scores and patient demographics, diabetes management, and health outcomes were examined. RESULTS: Participants took 10 minutes, on average, to complete the eNCQ. Total and Carbohydrate subscale scores (youth report) were negatively correlated with youth hemoglobin A1c (total r = -.38, carbohydrate r = -.38, Ps < .05), indicating that greater nutrition knowledge related to better glycemic control. Nutrition knowledge scores were generally high, but knowledge was negatively related to time since diabetes diagnosis ( r = -.276, P < .05). CONCLUSIONS: Findings support feasibility of the eNCQ to assess nutrition knowledge in routine clinical care. Following additional acceptability and validity testing, the eNCQ may identify families in need of further nutrition education. Nutrition assessment is particularly indicated for youth over one year since T1D diagnosis, as these families displayed lower nutrition knowledge and may need continuing education to maintain diabetes-specific nutrition knowledge over time.

Iterative development of a web-based intervention for families of young children with type 1 diabetes: DIPPer Academy.

OBJECTIVE: A new diagnosis of Type 1 diabetes mellitus (T1D) can be stressful for families as they are expected to learn a large amount of information regarding disease management and treatment in a short period of time. Currently, parents complete diabetes education at the time of diagnosis. However, this format may not be sustainable as rates of T1D climb. The current study aimed to develop an online platform to provide educational material in the form of video micro-lectures using an iterative, user-centered, design process. METHODS: In the first stage of development, parents of young children with T1D identified information they felt most important to their child's T1D care. In the second stage, healthcare providers contributed qualitative and quantitative feedback regarding the educational material and video mock-ups. The third stage involved parents of young children with T1D providing feedback on the completed video micro-lectures. RESULTS: Providers and parents reported that the videos were highly useful, important to T1D care, and the majority would recommend them to other parents. CONCLUSIONS: The iterative design process used by the research team incorporated multiple perspectives and ultimately developed educational resources that were well-received by providers, researchers, and parents. IMPLICATIONS FOR IMPACT STATEMENT: This study used an iterative, user-centered design to develop a series of web-based videos for parents of young children with type 1 diabetes. Primary stakeholders, both healthcare providers and parents, described videos as highly important, useful, enjoyable, and would recommend these resources to others. Parents rated videos highly across a variety of presentations that ranged in development time and cost, indicating that researchers can feasibly and cost-effectively create web-based resources for parents.

Parental depression and diabetes-specific distress after the onset of type 1 diabetes in children.

OBJECTIVE: To examine trajectories of two types of type 1 diabetes (T1D) specific distress (i.e., daily T1D management and worries about the future and long-term complications) and the moderating role of parental depression in parents of children newly diagnosed with T1D. METHOD: A total of 126 families of 5- to 9-year-olds with new-onset T1D enrolled in the study. One-hundred twenty-five families completed study measures at baseline, 102 at 6-month follow-up, and 89 at 12-month follow-up. Parents completed measures of depression and T1D-specific distress concerning daily T1D management and worries about the future and long-term complications at baseline and at 6- and 12-month follow-ups. We used multilevel modeling to examine 12-month trajectories of daily and long-term T1D-specific distress and to examine if parental depression modified these trajectories. RESULTS: Results showed a significant reduction in daily T1D-specific distress from baseline to 6-month follow-up and maintenance of daily T1D-specific distress from 6- to 12-month follow-up. The significant interaction of baseline parental depression and time indicated that parents with depressive symptoms had a smaller reduction in daily T1D-specific distress from baseline to 6-month follow-up compared to parents without depressive symptoms. Findings for long-term T1D-specific distress indicated that parents with depressive symptoms reported higher distress across all assessment points, with peak long-term T1D-specific distress for parents with depressive symptoms occurring at 6-month follow-up. CONCLUSION: Many parents experienced significant T1D-specific distress for a period of time following their child's initial diagnosis and this distress appears to be exacerbated by parental depressive symptoms.

Physical activity and health-related quality of life in children and adolescents: A systematic review and meta-analysis.

OBJECTIVE: The purpose of this study was to quantify the effect of physical activity (in both descriptive and intervention studies) on health-related quality of life (HRQOL) in children and adolescents from both healthy and chronic illness populations. METHOD: A systematic review of PubMed, PsycINFO, and ProQuest identified 33 studies of physical activity and HRQOL in youth, including descriptive and prepost intervention designs. RESULTS: In descriptive studies (N = 14), there was a small, positive association between physical activity and HRQOL based on child-reports (Hedges' g = .302, p < .001, 95% confidence interval, CI [.178, .426]) and a negligible association based on parent-proxy reports (Hedges' g = .115, p = .101, 95% CI [-.023, .253]). Intervention studies (N = 19) yielded a small, positive effect of physical activity intervention on HRQOL based on child-reports (Hedges' g = .279, p = .014, 95% CI [.057, .500]) and a medium, positive effect based on parent-proxy reports (Hedges' g = .522, p = .012, 95% CI [.117, .928]). Intervention effects were attenuated by removal of a single study. Hypothesized and exploratory moderators did not moderate the relationship between physical activity and HRQOL. CONCLUSIONS: Findings supported the primary hypothesis that physical activity was related to better HRQOL in youth, although the magnitude of these effects did not represent a minimal clinically important difference (MCID) in most studies. Future studies are needed to assess HRQOL in youth before and after exercise interventions to quantify the type, frequency, duration, and intensity of physical activity needed to change HRQOL.

Individual Differences in the Flexibility of Peripersonal Space.

The current study investigated individual differences in the flexibility of peripersonal space (i.e., representational space near the body), specifically in relation to trait claustrophobic fear (i.e., fear of suffocating or being physically restricted). Participants completed a line bisection task with either a laser pointer (Laser condition), allowing for a baseline measure of the size of one's peripersonal space, or a stick (Stick condition), which produces expansion of one's peripersonal space. Our results revealed that individuals high in claustrophobic fear had larger peripersonal spaces than those lower in claustrophobic fear, replicating previous research. We also found that, whereas individuals low in claustrophobic fear demonstrated the expected expansion of peripersonal space in the Stick condition, individuals high in claustrophobic fear showed less expansion, suggesting decreased flexibility. We discuss these findings in relation to the defensive function of peripersonal space and reduced attentional flexibility associated with trait anxieties.

Family-Based Behavioral Treatment for Childhood Obesity: Caretaker-Reported Barriers and Facilitators.

BACKGROUND: Family-based behavioral treatments are effective ways to promote children's weight management through healthy eating and exercise. However, programs typically have high attrition and low attendance. The aim of this study was to obtain in-depth caregiver input on barriers and facilitators to participate in a family-based, behavioral childhood obesity treatment program. METHODS: Three focus groups were facilitated among 21 parents/guardians at 2 school-based health centers and 1 federally qualified health center. Audio recordings were transcribed and uploaded into NVivo software to assist in thematic coding. RESULTS: Focus group participants were females aged 18-57 years, of whom 71% were black, and 81% were not married. Participants listed numerous barriers: lack of time, frustration from prior unsuccessful weight-loss attempts, and the perceived cost of healthy foods and exercise options. Facilitators included a convenient location, a supportive weight-loss program leader, and rewards for the child's progress. CONCLUSION: Future interventions should incorporate caregivers' perspectives to develop sustainable, feasible strategies for the treatment of childhood obesity.

Physical activity, mental health, and weight gain in a longitudinal observational cohort of nonobese young adults.

OBJECTIVE: To investigate the relationship among moderate-to-vigorous physical activity (MVPA), mental health symptoms, and weight gain in young adults. METHODS: Fifty-nine healthy men and women (age 26.8 ± 4.7 years, body mass index [BMI] 22.4 ± 2.3 kg/m(2) ) were assessed at baseline and year 2. Weight, BMI, fat mass by dual-energy X-ray absorptiometry, anxiety and depression by the SCL-90, and MVPA by accelerometry were assessed. Sex-stratified linear regression models were used to examine associations between baseline anxiety/depression and body composition change, then repeated controlling for baseline MVPA. RESULTS: Overall, weight, BMI, fat mass, and subcutaneous adiposity significantly increased at year 2 (P < 0.05). For women, a higher depression and anxiety score predicted increased weight, BMI, fat mass, and subcutaneous adiposity (P < 0.05). Controlling for MVPA attenuated these associations to nonsignificance. For men, MVPA did not alter the associations between anxiety and increased weight, BMI, fat mass, and subcutaneous adiposity (P < 0.05) or the associations between depression and decreased weight, BMI, fat mass, and subcutaneous adiposity (P < 0.05). CONCLUSIONS: Anxiety and depression were related to body composition change for young adults. In women, MVPA attenuated these associations to nonsignificance. MVPA may buffer the adverse effects of depression and anxiety symptoms on young women's weight gain.

Influence of Screen-Based Peer Modeling on Preschool Children's Vegetable Consumption and Preferences.

OBJECTIVE: To determine the influence of screen-based peer modeling on children's vegetable consumption and preference. METHODS: A total of 42 children aged 3-5 years were randomly assigned to view individually a video segment of peers consuming a modeled vegetable (bell pepper), vs a nonfood video segment or no video. Analysis of covariance models examined bell pepper preference and consumption during initial video exposure (day 1) and without video exposure (days 2 and 7), adjusted for age, sex, body mass index, and initial bell pepper consumption. RESULTS: Children in the vegetable condition ate more bell peppers (15.5 g) than did those in the control condition (5.9 g; P = .04; model η(2) = 0.85) on day 7, with no differences on days 1 or 2. Among children who ate the modeled vegetable, those in the vegetable DVD condition reported greater preference for eating the vegetable again (P = .01). CONCLUSIONS AND IMPLICATIONS: Screen-based peer modeling is a promising tool to influence children's vegetable consumption.

Better Together: Outcomes of Cooperation Versus Competition in Social Exergaming.

Children and adolescents most often play active videogames, or exergames, in a social environment. Social play may enhance the potential benefits of an exergaming experience, much like group exercise and team sports are observed to improve physical activity-related outcomes above those of solitary exercise. Two ubiquitous elements of exergames are cooperation and competition. Previous literature suggests that cooperative and competitive aspects of exergames may affect physiological and psychosocial changes. Competitive play has been found to increase energy expenditure and aggression in short bouts of exergaming. Cooperative exergaming has been found to increase motivation, promote continued play, enhance self-efficacy, and increase pro-social behaviors. In one study, a cooperative exergaming condition also resulted in significant weight loss for overweight and obese adolescents. Individual player differences such as individual preferences, competitiveness, weight status, age, gender, and ethnicity may moderate effects. Although the current volume of literature on competition and cooperation in exergaming is small, social exergames hold promise as an engaging alternative to traditional physical activity interventions and may promote a broad range of positive outcomes for children and adolescents. Principles of cooperation and competition are applicable for developers of health-promoting games. Future research is needed to further understand the mechanisms of how competition and cooperation in social exergaming impact physiological and psychosocial outcomes.
