Daily mindfulness, negative affect, and eating behaviors in adolescents at risk for excess weight gain.

OBJECTIVE: Loss-of-control and overeating are common in adolescents with high body mass index (BMI). Mindfulness may affect negative affect, and both may relate to loss-of-control and overeating. Yet, there is limited understanding of these associations in adolescents' daily lives. METHODS: Forty-five adolescents (77% female; Mage = 14.4 years, SDage = 1.7 years) with high weight (92% with BMI [kg/m2 ] ≥85th percentile for age/sex) provided daily, repeated measurements of mindfulness, negative affect, loss-of-control, and overeating for ~7 days (M = 5.6 days; range = 1-13). Multilevel mixed modeling was conducted to test within-person (intraindividual) and between-person (interindividual) associations for the same-day (concurrent) and next-day (time-ordered/prospective). RESULTS: There were within-person and between-person associations of higher mindfulness with lower negative affect on the same-day and next-day. Greater between-person mindfulness related to lower odds of adolescents' loss-of-control occurrence (same-day) and conversely, more perceived control over eating (same-day and next-day). Greater within-person mindfulness related to less odds of next-day overeating. DISCUSSION: Dynamic relations exist among mindfulness, negative affect, and eating in adolescents at-risk for excess weight gain. Mindfulness may be an important element to consider in loss-of-control and overeating. Future work using momentary-data within an experimental design would help disentangle the intraindividual effects of increasing mindfulness/decreasing negative affect on disordered eating. PUBLIC SIGNIFICANCE: Loss-of-control and overeating are common in teenagers with high weight. Greater mindfulness-present-moment, non-judgmental attention-and less negative emotions may relate to healthier eating, but we do not know how these processes play out in teenagers' daily lives. Addressing this knowledge gap, the current findings showed that greater daily mindfulness, but not negative affect, related to less loss-of-control/overeating, suggesting the importance of mindfulness for eating patterns in teenagers' daily lives.

Mindfulness-Based Interventions: Focus on Pediatric Type 1 and Type 2 Diabetes.

PURPOSE OF REVIEW: Mindfulness-based interventions (MBIs) focus on promoting nonjudgmental, purposeful awareness of the present experience, and they include specific components such as body scan, meditation, and breathing techniques for healthier coping with stress and reduced negative affect. In adult populations with chronic illness (e.g., type 1 diabetes [T1D], type 2 diabetes [T2D], overweight), MBIs have been shown to improve psychosocial outcomes with some improvements in health outcomes as well. Youth with T1D/T2D frequently experience heightened depression as well as diabetes distress, which are associated with less frequent blood glucose monitoring, insulin administration, and nutrition oversight. Thus, MBIs have potential to alleviate psychosocial distress in youth with T1D/T2D and also improve health outcomes. This paper is a review of the literature on potential psychosocial and health benefits of MBIs for youth with T1D/T2D. RECENT FINDINGS: Among youth with T1D/T2D, MBIs have been shown to reduce symptoms of depression and diabetes distress. Improvements in health outcomes, such as A1c, have been inconsistent across studies. Although research on the efficacy of MBIs to improve psychosocial and health outcomes in youth with T1D/T2D is promising, this area of study is in its early stages. Future investigation of MBIs in youth with T1D and T2D is warranted, recognizing that these are heterogeneous groups with potential benefit of specifically tailored interventions.

Within-Person variations in mindfulness mediate effects of daily stressors on psychological distress in adolescence.

OBJECTIVE: We tested two competing models linking daily stress, mindfulness, and psychological distress in adolescence: 1) whether daily mindfulness moderates the impact of daily stressors on psychological distress or 2) whether mindfulness mediates the relationship between greater daily stressors and psychological distress. METHODS: Every evening for a week, 138 adolescents completed ecological momentary assessments (EMAs). Daily diaries assessed negative events, work-school conflict, mindfulness, and perceived stress. Multilevel mediation and moderation were tested. RESULTS: Results indicated that there were meaningful variations in adolescent mindfulness from day-to-day, and supported mediation rather than moderation; the within-person association between stressors and psychological distress was mediated by mindfulness at the daily level. CONCLUSION: It may be too challenging for adolescents to remain in a mindful state during stress to effectively use mindfulness as a buffer. Instead, daily stressors may indirectly impact psychological distress through decreasing mindfulness.

Mindfulness-based intervention in adolescents at risk for excess weight gain: 1.5-year follow-up of pilot randomized controlled trial.

BACKGROUND: Mindfulness-based intervention (MBI) may offer a novel means of preventing excess weight gain in adolescents, theoretically by decreasing stress-eating through altering executive functioning (EF) and food-reward sensitivity. METHODS: N = 54 12-17y girls and boys at-risk for excess weight gain (i.e., BMI ≥70th percentile or two biological parents with reported obesity [BMI ≥30 kg/m2]) participated in a 1.5-year follow-up of a pilot randomized controlled trial comparing 6-week/6-session MBI (n = 29) and a health education (HE) control (n = 25). Laboratory stress-eating, food-reward sensitivity, EF, perceived stress, and BMI/adiposity were re-assessed at 1.5-years with validated measures. Changes from baseline to 1.5-year follow-up were explored with ANCOVA, accounting for the respective baseline outcome, age, and sex. RESULTS: Compared to MBI (M = -21, SE = 59), HE had greater increases in stress-eating from baseline to 1.5-years (M = 194, SE = 63, Cohen's d = 0.59, p = .01). There were no other between-condition differences. DISCUSSION: MBI may prevent worsening stress-eating for adolescents at-risk for excess weight gain. The potential for MBI as an intervention for stress-eating and ultimately, weight stabilization warrants testing in an adequately-powered trial.

Health effects of COVID-19 for vulnerable adolescents in a randomized controlled trial.

Emerging evidence suggests the coronavirus disease 2019 (COVID-19) pandemic is adversely affecting adolescents' mental health and health behaviors, particularly among those with preexisting mental health conditions and from lower socioeconomic backgrounds. However, direct tests of changes in health outcomes among vulnerable adolescents from before to during COVID-19 are limited. In addition, little is known about how to buffer adolescents, particularly those who are most vulnerable, against stress-related decrements in health. This randomized controlled trial begins to fill these gaps in the literature by exploring changes in mental health, health behaviors, executive function, emotion regulation, and mindfulness among vulnerable adolescents involved in a mentoring program during the COVID-19 pandemic. It also examined to what extent there were protective benefits of incorporating mindfulness training within a mentoring program for buffering adolescents from negative pandemic health effects. Thirty-five adolescents (Mage = 12.9, 37% female) and 32 parents (Mage = 44.75, 80% female) completed questionnaires at baseline (February 2020) and follow-up (July 2020). There were few significant reductions in health; instead, on average, youth reported improvements in sleep, emotion regulation, executive function, and mindfulness over time. Adolescents randomized to mentoring + mindfulness displayed significantly less posttraumatic stress disorder (PTSD) symptomatology and emotional impulsivity at follow-up, compared to the mentoring-as-usual condition. These pilot findings suggest that mentoring with a mindfulness training component may offer an effective strategy for protecting adolescents from deteriorations in health outcomes during COVID-19. Further, there may be unique benefits of mindfulness training for vulnerable youth as a way to adapt to stressful events. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The role of mindfulness in associations among depression symptoms, sleep duration, and insulin resistance in adolescents.

Sleep difficulties may be one explanatory factor in the association between depression and insulin resistance; yet, explicit tests of this hypothesis are lacking. We determined if there was an indirect effect of depression symptoms on insulin resistance through sleep duration in adolescents at risk for excess weight gain. We also investigated whether dispositional mindfulness moderated the interconnections among depression, sleep, and insulin resistance. Ninety adolescents (14.2 ± 1.6y; 50% female) at risk for excess weight gain (body mass index [BMI, kg/m2] z score 1.6 ± 0.6) participated in the cross-sectional, baseline phase of a health behaviors study. Depression was assessed with the Center for Epidemiologic Studies-Depression Scale, sleep duration with the Sleep Habits Survey, and mindfulness with the Mindful Attention and Awareness Scale. Homeostatic model assessment of insulin resistance was determined from fasting insulin and glucose. The product-of-coefficients method was used to test the indirect effect of depression on insulin resistance through sleep duration, accounting for age, sex, BMIz, puberty, and socioeconomic status (SES). Dispositional mindfulness was tested as a moderator of the associations among depression, sleep, and insulin resistance. There was a significant indirect effect of depression on insulin resistance through sleep duration, controlling for age, sex, BMIz, puberty, and SES, 95%CI [0.001, 0.05]. Dispositional mindfulness moderated the association between sleep duration and insulin resistance, such that lower sleep duration related to greater insulin resistance only among adolescents with lower mindfulness (p < .001). Short sleep may be one explanatory factor in the depression-insulin resistance connection in adolescents at risk for excess weight gain. Adolescents with poorer mindfulness and short sleep are at highest risk for insulin resistance, whereas higher mindfulness may be protective.

Effects of a mindfulness-induction on subjective and physiological stress response in adolescents at-risk for adult obesity.

BACKGROUND: Mindfulness-training may benefit stress response and stress-eating, yet few studies have experimentally tested these effects in adolescents. In this short communication, we report whether a brief mindfulness-induction affected acute stress response and stress-eating in adolescents at-risk for adult obesity. We explored disordered eating as a moderator. METHOD: Twenty-nine adolescents (age 14 ± 2 y) at-risk for adult obesity participated in a within-subjects, randomized crossover experiment. Following a 10-minute mindfulness or neutral-induction on different days in random order, the Trier Social Stress Test adapted for adolescents was administered, followed by an ad libitum lunch meal. Physiological stress response (heart rate, blood pressure) and subjective stress response (anxiety, mindlessness) were determined with area under the curve with respect to increase. Stress-eating was measured as test meal energy consumed. Global disordered-eating and binge-eating were assessed with the Eating Disorders Examination-Questionnaire. RESULTS: Relative to a neutral-induction, a mindfulness-induction reduced state anxiety response (p = .04). There were significant interactions of induction-type by global disordered-eating (p = .02) and binge-eating (p = .03), such that the mindfulness-induction most reduced anxiety response in adolescents with relatively lower global disordered-eating and those with no binge-eating. Induction-type also interacted with binge-eating in predicting diastolic blood pressure (p = .03). A mindfulness-induction, versus neutral-induction, most reduced diastolic blood pressure response in adolescents with binge-eating. CONCLUSIONS: Brief mindfulness-training may alter some aspects of acute stress response, with variations by disordered-eating. Future research should test alternative mindfulness induction-types (e.g., acceptance/self-compassion) to improve our understanding of how mindfulness-training may benefit adolescents at-risk for adult obesity.

One-Year Follow-Up of a Randomized Controlled Trial Piloting a Mindfulness-Based Group Intervention for Adolescent Insulin Resistance.

INTRODUCTION: To explore if a brief mindfulness-based intervention (MBI) leads to sustained, improved clinical outcomes in adolescents at-risk for type 2 diabetes (T2D). METHODS: Participants were 12-17y girls with overweight/obesity, elevated depression symptoms, and T2D family history participating in a randomized, controlled pilot trial of a six-session MBI vs. cognitive-behavioral therapy (CBT) group. At baseline and 1-year, mindfulness, depression, insulin resistance (IR), and body composition were assessed with validated instruments. RESULTS: One-year retention was 71% (n = 12) in MBI; 81% (n = 13) in CBT. At 1-year, depression decreased (Cohen's d = 0.68) and IR decreased (d = 0.73) in adolescents randomized to MBI compared to those in CBT. There were no significant between-condition differences in mindfulness, adiposity, or BMI. DISCUSSION: One-year outcomes from this randomized, controlled pilot trial suggest that brief MBI may reduce depression and IR in at-risk adolescents. Replication and exploration of mechanisms within the context of a larger clinical trial are necessary. CLINICAL TRIAL REGISTRATION: www.ClinicalTrials.gov, identifier NCT02218138.

Mindfulness-based group intervention in adolescents at-risk for excess weight gain: A randomized controlled pilot study.

OBJECTIVES: To assess feasibility/acceptability of a mindfulness-based approach to excess weight prevention in adolescents at-risk for excess weight gain. To pilot test efficacy of a mindfulness-based intervention for improving food reward sensitivity, stress-eating, executive function (EF), and BMI/adiposity. METHODS: A pilot randomized controlled trial was conducted with 12-17y adolescents at-risk for excess weight gain based on above-average weight (body mass index [BMI]≥70%ile) or parental history of obesity (BMI≥30 kg/m2). Adolescents were randomized to a mindfulness-based (n = 29) or health education control group (n = 25) that met for six weekly one-hour sessions. Feasibility/acceptability were determined from attendance and acceptability survey ratings. At baseline, six-week and six-month follow-up, adolescents' perceived stress was measured with the Perceived Stress Scale, food reward sensitivity with a behavioral task, stress-eating during a laboratory test meal, and EF with the parent-reported Behavior Rating Inventory of Executive Function and NIH Toolbox. At the same intervals, BMI indices and body fat by air displacement plethysmography were assessed in a fasted state. RESULTS: Median session attendance was 6:6 sessions in both conditions; program acceptability ratings were above-average. Compared to health education, adolescents in mindfulness had lower food reward sensitivity at six-months (Cohen's d = 0.64, p = .01). There were no between-condition differences in BMI (mindfulness vs. health educationΔsix-months 95%CI 0.20, 1.52 kg/m2 vs. 0.21, 1.62 kg/m2) or adiposity (-3.64, -0.61% vs. -4.31, -1.04%) changes. CONCLUSIONS: A mindfulness-based group intervention is feasible/acceptable among adolescents at-risk for excess weight. In this pilot sample, mindfulness and health education were equivocal for BMI/adiposity outcomes. Future trials with a larger, adequately-powered sample and longer-term follow-up are necessary to test efficacy of a mindfulness-based intervention for food reward sensitivity, stress-eating, EF, and stabilizing growth trajectories in youth at-risk for adult obesity.

Relationship of Mindfulness to Distress and Cortisol Response in Adolescent Girls At-Risk for Type 2 Diabetes.

Altered stress response theoretically contributes to the etiology of cardiometabolic disease. Mindfulness may be a protective buffer against the effects of stress on health outcomes by altering how individuals evaluate and respond to stress. We engaged adolescent girls at risk for developing Type 2 diabetes in a cold-pressor test in order to determine the relationship of dispositional mindfulness to cortisol response and subjective stress, including perceived pain and unpleasantness during the stressor, and negative affect following the stressor. We also evaluated mindfulness as a moderator of psychological distress (depressive/anxiety symptoms) and stress response. Participants were 119 girls age 12-17 years with overweight/obesity, family history of diabetes, and mild-to-moderate depressive symptoms. Greater mindfulness was associated with less perceived pain and negative affect, but was unrelated to cortisol response to the stressor. Regardless of mindfulness, greater depressive/anxiety symptoms related to a more blunted cortisol response. Mindfulness might promote better distress tolerance in adolescents at risk for diabetes by altering how youth perceive and relate to acute stress, rather than through altering the physiological stress response. At all levels of mindfulness, depressive/anxiety symptoms relate to greater blunting of cortisol response. Findings contribute to emerging literature on the role of mindfulness in promoting the mental and physical health and well-being of individuals at risk for Type 2 diabetes.

Mindfulness and laboratory eating behavior in adolescent girls at risk for type 2 diabetes.

Mindfulness-based intervention has become increasingly popular to address disinhibited eating in obesity and type 2 diabetes (T2D). Theoretically, present-moment attention promotes the ability to recognize and respond to internal hunger cues and to differentiate physiological hunger from other stimuli. Yet, there is limited research describing the relationship of mindfulness with disinhibited eating patterns in adolescents. In this study, we evaluated the relationship of dispositional mindfulness to laboratory eating in 107 adolescent (12-17 years) girls at risk for T2D. Adolescents reported dispositional mindfulness, were evaluated for recent loss-of-control-eating (LOC-eating) by interview, and participated in two successive, standardized laboratory test meals to assess eating when hungry as well as eating in the absence of hunger (EAH). Adolescents rated state appetite throughout the test meal paradigms. In analyses adjusting for body composition and other possible confounds, mindfulness was inversely related to caloric intake during the EAH paradigm. Mindfulness did not relate to energy intake when hungry. Instead, there was a significant interaction of reported LOC-eating by state hunger, such that girls with recent, reported LOC-eating and high state hunger consumed more calories when hungry, regardless of mindfulness. Findings suggest that in girls at risk for T2D, mindfulness may play a role in disinhibited eating. A propensity for LOC-eating may be most salient for overeating in a high hunger state.

Mindfulness-based Group Intervention for an Adolescent Girl at Risk for Type 2 Diabetes: A Case Report.

CONTEXT: Behavioral lifestyle interventions to lower body mass index (BMI; kg/m2) are the standard approach for preventing adolescent-onset type 2 diabetes (T2D). Unfortunately, existing programs have had limited long-term success of lessening insulin resistance, the key physiological risk indicator for T2D. Underlying psychosocial factors, particularly depressive symptoms, have been related to insulin resistance, independent of BMI or body fat. Preliminary evidence indicates that mindfulness-based programs show promise for intervening with depression and T2D; yet, this approach is novel and data in adolescents are scarce. OBJECTIVE: The objectives of this study were (1) to evaluate the benefits, and potential underlying mechanisms, of a mindfulness-based intervention in adolescents at-risk for T2D with depressive symptoms and (2) to consider clinical implementation with this specific, psychologically, and medically at-risk adolescent population. DESIGN AND SETTING: The research team conducted a case study report. The setting was an outpatient therapy clinic and research laboratory at a university. PARTICIPANT: The participant was a 16-y-old female with elevated depressive symptoms, obesity, and insulin resistance, and a family history of T2D. INTERVENTION AND OUTCOMES: The intervention was a 6-wk mindfulness-based group program. The key outcomes were patterns of change in trait mindfulness, depression, and insulin resistance in the course of a 1-y follow-up. Secondary outcomes were patterns of change in reported-overeating patterns and cortisol awakening response. RESULTS: Compared with her scores at baseline, the participant displayed a pattern of increased trait mindfulness, decreased depressive symptoms, and lessening of insulin resistance immediately following the group program and at 1 y. BMI and body fat were stable. There was a remission in reported-overeating and a pattern of declining cortisol awakening response 1 y later. Participant feedback on the intervention was generally positive but also provided potential modifications to strengthen acceptability and effectiveness. CONCLUSIONS: The current case results suggest that teaching mindfulness skills to adolescent girls at risk for T2D with depressive symptoms may offer distinctive advantages for treating depression and T2D risk. Clinical implications for increasing the success of implementing mindfulness-based programs in this population include a focus on promotion of social connectedness within the group, implementation of strategies to increase adherence to home practice activities, and the use of facilitation techniques to promote concrete understanding of abstract mindfulness concepts. Future, adequately powered clinical trial data are required to test therapeutic mechanisms and recommended adaptations.

Pilot randomized controlled trial of a mindfulness-based group intervention in adolescent girls at risk for type 2 diabetes with depressive symptoms.

OBJECTIVE: (1) Evaluate feasibility and acceptability of a mindfulness-based group in adolescent girls at-risk for type 2 diabetes (T2D) with depressive symptoms, and (2) compare efficacy of a mindfulness-based versus cognitive-behavioral group for decreasing depressive symptoms and improving insulin resistance. DESIGN AND SETTING: Parallel-group, randomized controlled pilot trial conducted at a university. PARTICIPANTS: Thirty-three girls 12-17y with overweight/obesity, family history of diabetes, and elevated depressive symptoms were randomized to a six-week mindfulness-based (n=17) or cognitive-behavioral program (n=16). INTERVENTIONS: Both interventions included six, one-hour weekly group sessions. The mindfulness-based program included guided mindfulness awareness practices. The cognitive-behavioral program involved cognitive restructuring and behavioral activation. MAIN OUTCOME MEASURES: Adolescents were evaluated at baseline, post-intervention, and six-months. Feasibility/acceptability were measured by attendance and program ratings. Depressive symptoms were assessed by validated survey. Insulin resistance was determined from fasting insulin and glucose, and dual energy x-ray absorptiometry was used to assess body composition. RESULTS: Most adolescents attended ≥80% sessions (mindfulness: 92% versus cognitive-behavioral: 87%, p=1.00). Acceptability ratings were strong. At post-treatment and six-months, adolescents in the mindfulness condition had greater decreases in depressive symptoms than adolescents in the cognitive-behavioral condition (ps<.05). Compared to the cognitive-behavioral condition, adolescents in the mindfulness-based intervention also had greater decreases in insulin resistance and fasting insulin at post-treatment, adjusting for fat mass and other covariates (ps<.05). CONCLUSIONS: A mindfulness-based intervention shows feasibility and acceptability in girls at-risk for T2D with depressive symptoms. Compared to a cognitive-behavioral program, after the intervention, adolescents who received mindfulness showed greater reductions in depressive symptoms and better insulin resistance.

Mindfulness and eating behavior in adolescent girls at risk for type 2 diabetes.

OBJECTIVE: The purpose of this investigation was to examine the relationship of dispositional mindfulness to binge eating and associated eating attitudes and behaviors among adolescent girls at risk for type 2 diabetes (T2D). METHODS: Participants were 114 overweight or obese adolescents enrolled in a study of girls with a family history of T2D and mild depressive symptoms. Adolescent self-reports of mindfulness, eating in the absence of hunger, and depressive symptoms were collected. An interview was administered to determine presence of binge eating episodes and a behavioral task was used to assess the reinforcing value of food relative to other nonsnack food rewards. Body composition was assessed using dual-energy X-ray absorptiometry. RESULTS: In analyses accounting for race, percent body fat, lean mass, height, age, and depressive symptoms, dispositional mindfulness was associated with a lower odds of binge eating (p = .002). Controlling for the same potential confounds, mindfulness was also inversely associated with eating concern, eating in the absence of hunger in response to fatigue/boredom, and higher food reinforcement relative to physical activity (all p < .05). DISCUSSION: In girls with a family history of T2D, independent of body composition and depressive symptoms, intraindividual differences in mindfulness are related to binge eating and associated attitudes and behaviors that may confer risk for obesity and metabolic problems. Further research is needed to determine the extent to which mindfulness plays a role in the etiology and/or maintenance of disinhibited eating in adolescents at risk for T2D.
