Real-time assessment of heart rate variability and loss of control eating in adolescent girls: A pilot study.

ABSTRACT: OBJECTIVE:Studying physiologic underpinnings of loss-of-control (LOC) eating may inform its etiology and contribute to intervention efforts. We therefore examined temporal relationships between autonomic indices [heart rate (HR), heart rate variability (HRV)] and LOC-eating in the natural environment. METHOD:For two days, adolescents (n?=?17, 14.77?±?1.55 years, BMI-Z 2.17?±?0.48) with LOC-eating reported on LOC using an electronic device while HR and HRV were assessed continuously using Holter monitoring. RESULTS:Higher HR and lower HRV in the 30-minutes before eating were significantly associated with LOC-eating overall (p's? 0.44). Examined categorically, HR was significantly higher, and HRV significantly lower, prior to high-LOC compared to low-LOC episodes (p's?

Heart Rate Variability and Laboratory-Based Loss-of-Control Eating in Children and Adolescents.

Project description:Among youth, greater heart rate (HR) and lesser HR variability (HRV) are precursors to loss-of-control (LOC) eating episodes in the natural environment. However, there are limited data examining whether pre-meal HR and HRV are associated with greater LOC-eating in the laboratory setting. We therefore examined temporal relationships between pre-meal HR, frequency- and time-based metrics of pre-meal HRV, perceived LOC-eating, and energy intake during a meal designed to simulate a LOC-eating episode. Among 209 participants (54.5% female, 12.58 ± 2.72 years, 0.52 ± 1.02 BMIz), 19 reported LOC-eating in the prior month. Perceived LOC-eating during the laboratory meal was not significantly linked to pre-meal HR (p = 0.37), but was positively related to pre-meal HRV (ps = 0.02-0.04). This finding was driven by youth with recent LOC-eating, as these associations were not significant when analyses were run only among participants without recent reported LOC-eating (p = 0.15-0.99). Pre-meal HR and HRV were not significantly related to total energy intake (ps = 0.27-0.81). Additional research is required to determine whether early-stage pediatric LOC-eating is preceded by a healthy pre-meal stress response. Longitudinal studies could help clarify whether this pattern becomes less functional over time among youth who develop recurrent LOC-eating episodes.

Cognitive Behavioral Treatment for Recurrent Binge Eating in Adolescent Girls: A Pilot Trial.

Project description:There is a need for treatment interventions to address the high prevalence of disordered eating throughout adolescence and early adulthood. We developed an adolescent-specific manualized CBT protocol to treat female adolescents with recurrent binge eating and tested its efficacy in a small, pilot randomized controlled trial. We present lessons learned in recruiting adolescents, a description of our treatment approach, acceptability of the treatment for teens and parents, as well as results from the pilot trial. Participants in the CBT group had significantly fewer posttreatment eating binges than those in a treatment as usual/delayed treatment (TAU-DT) control group; 100% of CBT participants were abstinent at follow-up. Our results provide preliminary support for the efficacy of this adolescent adaptation of evidence-based CBT for recurrent binge eating. The large, robust effect size estimate observed for the main outcome (NNT=2) places this among the larger effects observed for any mental health intervention.

History of weight control attempts among adolescent girls with loss of control eating.

Project description:OBJECTIVE:Loss of control (LOC) eating and a weight control attempt (WCA) history during adolescence are important behavioral risk factors for eating disorders and obesity. The current study investigated the significance of the presence of a WCA history among adolescent girls with LOC eating. METHOD:Participants were 114 obesity-prevention-seeking 12-17-year-old (M = 14.5, SD = 1.7 years) girls who were between the 75th and 97th body mass index (BMI) percentile (BMI-z: M = 1.5, SD = 0.3) and reported LOC eating episodes during the previous month (M = 4.0, SD = 4.9 episodes; Median = 2.0). Measures included the Eating Disorder Examination to assess LOC eating, eating pathology, and WCA history, and self-report questionnaires for symptoms of general psychopathology. Eating behavior was observed during a laboratory meal designed to capture a LOC eating episode. RESULTS:67.5% reported a WCA history. As compared to girls without a WCA history (no-WCA), those with a WCA history (WCA) had greater disordered eating attitudes and depressive symptoms (ps < .04). There were no significant group differences in BMI-z or LOC eating frequency (ps > .10). During the laboratory meal, WCA consumed less energy from snack-type foods than no-WCA (M = 245.0, SD = 156.1 vs. M = 341.6, SD = 192.3 kcal; p = .01). CONCLUSIONS:Reported WCAs are highly prevalent and are associated with greater psychopathology symptoms among adolescent girls with LOC eating. Prospective data are needed to determine whether these overlapping risk behaviors confer differential vulnerability for developing eating disorders and obesity.

Interpersonal problem areas and alexithymia in adolescent girls with loss of control eating.

Project description:This study investigated the links among interpersonal problem areas, depression, and alexithymia in adolescent girls at high risk for excessive weight gain and binge eating disorder. Participants were 56 girls (Mage = 14.30, SD = 1.56; 53% non-Hispanic White) with a body mass index (BMI, kg/m(2)) between the 75th and 97th percentiles (MBMI z = 1.57, SD = 0.32). By design, all participants reported loss of control eating patterns in the past month. Adolescents were individually interviewed prior to participating in a group interpersonal psychotherapy obesity and eating disorder prevention program, termed IPT for the prevention of excessive weight gain (IPT-WG). Participants' interpersonal problem areas were coded by trained raters. Participants also completed questionnaires assessing depression and alexithymia. Primary interpersonal problem areas were categorized as interpersonal deficits [as defined in the eating disorders (ED) literature] (n = 29), role disputes (n = 22), or role transitions (n = 5). Girls with interpersonal deficits-ED had greater depressive symptoms and alexithymia than girls with role disputes (p's ? 0.01). However, girls with role transitions did not differ from girls with interpersonal deficits-ED or role disputes. Interpersonal problem area had an indirect association with depression via alexithymia; interpersonal deficits-ED were related to greater alexithymia, which in turn, was related to greater depressive symptoms (p = 0.01). Among girls at risk for excess weight gain and eating disorders, those with interpersonal deficits-ED appear to have greater distress as compared to girls with role disputes or role transitions. Future research is required to elucidate the impact of interpersonal problem areas on psychotherapy outcomes.

Real-time analysis of heart rate variability during aerobic exercise in patients with cardiovascular disease.

Project description:BackgroundExercise therapy for cardiovascular disease (CVD) is mainly evaluated based on the heart rate (HR) or Borg scale. However, these indices can be unreliable depending on the patient's medication or their subjective decisions; thus, alternative methods are required for easier and safer implementation of aerobic exercise. Here, we examined whether real-time analysis of HR variability (HRV) can help maintain exercise intensity at the ventilatory threshold (VT) during exercise.MethodsTwenty-eight patients with CVD treated at Keio University Hospital between August 2018 and March 2020 were enrolled. Initially, oxygen uptake (VO2) and HR at the VT were determined using the cardiopulmonary exercise test. Patients then performed aerobic exercise on a stationary bicycle for 30 min while a parameter of HRV, the high-frequency (HF) component, was monitored in real time using an electrocardiograph. The work rate during exercise was adjusted every 2 min to maintain the HF range between 5 and 10. The VO2 and HR values, recorded every 2 min during exercise, were compared with those at VT. The Bland-Altman method was used to confirm similarity.ResultsVO2 and HR during exercise were closely correlated with those at VT (e.g., 19 min after exercise initiation; VO2: r = 0.647, HR: r = 0.534). The Bland-Altman plot revealed no bias between the mean values (e.g., 19 min; VO2: -0.22 mL/kg/min; HR: -0.07/min).ConclusionReal-time HRV analysis with electrocardiograph alone during exercise can provide continuous and non-invasive exercise intensity measurements at VT, promoting safer and effective exercise strategies.

Heart Rate Variability, Vagus Nerve and Cancer

Project description:In France, new cancer cases keep on increasing with around 150 000 deaths yearly. Cancer therapy research is constantly evolving. Indeed, several studies explore new treatments or their combination with conventional cancer treatments. But, at the same time, complementary and alternative medicines, as osteopathy, remain little explored upon their role in the combination with conventional therapy. Several studies showed indirect interaction between vagus nerve and cancer. Firstly, vagus nerve regulates homeostasis and immunity by reducing systemic inflammation while maintaining local inflammation and antitumor effects. Secondly, vagus nerve stimulation increases Heart Rate Variability (HRV). Moreover, a higher HRV is associated with an improvement of vital prognosis in cancer patients. Vagus nerve could be stimulated by noninvasive osteopathic manipulations. This prospective, monocentric and randomized study is a collaboration between the Centre Hospitalier d’Avignon and the Institut de Formation en Ostéopathie du Grand Avignon. It focuses on using noninvasive osteopathic mobilizations to stimulate vagus nerve. Indeed, this study aims to evaluate effects of vagus nerve osteopathic stimulations on HRV in patients with lung cancer, colorectal cancer, Non Hodgkin Lymphoma or Multiple Myeloma. More specifically, this study will tell us whether vagus nerve noninvasive osteopathic stimulations induce increase of HRV associated with a decrease of systemic inflammation and an improvement of patient’s quality of life.

Comparison of overweight and obese military-dependent and civilian adolescent girls with loss-of-control eating.

Project description:ObjectiveLimited data suggest that the children of U.S. service members may be at increased risk for disordered-eating. To date, no study has directly compared adolescent military-dependents to their civilian peers along measures of eating pathology and associated correlates. We, therefore, compared overweight and obese adolescent female military-dependents to their civilian counterparts along measures of eating-related pathology and psychosocial functioning.MethodAdolescent females with a BMI between the 85th and 97th percentiles and who reported loss-of-control eating completed interview and questionnaire assessments of eating-related and general psychopathology.ResultsTwenty-three military-dependents and 105 civilians participated. Controlling for age, race, and BMI-z, military-dependents reported significantly more binge episodes per month (p < 0.01), as well as greater eating-concern, shape-concern, and weight-concern (p's < 0.01) than civilians. Military-dependents also reported more severe depression (p < 0.05).DiscussionAdolescent female military-dependents may be particularly vulnerable to disordered-eating compared with civilian peers. This potential vulnerability should be considered when assessing military-dependents.

Perceived Family Functioning in Relation to Energy Intake in Adolescent Girls with Loss of Control Eating.

Project description:Family functioning is hypothesized to influence the development, maintenance, and treatment of obesity and eating disorders. However, there are limited data examining family functioning in relation to energy intake in the laboratory among youth at high-risk for eating disorders and excess weight gain. Therefore, we examined the relationship between perceived family functioning and energy intake during a laboratory test meal designed to model a binge episode. We performed hierarchical multiple regression analyses among 108 adolescent girls in an excess weight gain prevention trial. Participants were at high-risk for eating disorders and excess weight gain due to reports of loss of control eating (LOC) and high body mass index (BMI). Participants completed the Family Adaptability and Cohesion Scale III to assess family adaptability and cohesion. Following an overnight fast, girls consumed lunch from a laboratory test meal. Poorer family adaptability, but not cohesion, was associated with lower percentage of total energy intake from protein and greater percentage of total energy intake from carbohydrates. Neither adaptability nor cohesion were significantly associated with total intake. We conclude that among girls with LOC eating and high BMI, poor reported family adaptability is associated with greater consumption of obesity-promoting macronutrients during binge episodes. Directionality and temporality of this association between unhealthy consumption and family rigidity requires further study.

Night Eating Among Latinos With Diabetes: Exploring Associations With Heart Rate Variability, Eating Patterns, and Sleep.

Project description:ObjectivesWe explored associations between night eating and health outcomes in Latinos with type 2 diabetes.MethodsParticipants (n = 85) completed surveys, were measured for anthropometrics, provided blood samples, and wore Holter monitors for 24 hours to assess heart rate variability.ResultsParticipant mean age was 60.0 years, hemoglobin A1c was 8.7%, most preferred Spanish (92%), and had less than a high school education (76%). Compared with their counterparts who denied night eating, night eaters had lower heart rate variability in the low (Cohen's d = -0.55; P = 0.04) and very-low-frequency bands (d = -0.54, P = 0.05), and reported more emotional eating (d = 0.52, P = 0.04), and poorer sleep quality (Cohen's h = 0.64). They did not differ on beverage intake or depressive symptoms. In regression that included depressive symptoms, associations between night eating and outcomes became nonsignificant.Conclusions and implicationsNight eaters demonstrated worse health outcomes. If results are replicated, nutrition education for this population might focus on night eating.

Non-invasive real-time autonomic function characterization during surgery via continuous Poincare quantification of heart rate variability.

Project description:Heart rate variability (HRV) provides an excellent proxy for monitoring of autonomic function, but the clinical utility of such characterization has not been investigated. In a clinical setting, the baseline autonomic function can reflect ability to adapt to stressors such as anesthesia. No monitoring tool has yet been developed that is able to track changes in HRV in real time. This study is a proof-of-concept for a non-invasive, real-time monitoring model for autonomic function via continuous Poincaré quantification of HRV dynamics. Anonymized heart rate data of 18 healthy individuals (18-45 years) undergoing minor procedures and 18 healthy controls (21-35 years) were analyzed. Patients underwent propofol and fentanyl anesthesia, and controls were at rest. Continuous heart rate monitoring was carried out from before aesthetic induction to the end of the surgical procedure. HRV components (sympathetic and parasympathetic) were extracted and analyzed using Poincaré quantification, and a real-time assessment tool was developed. In the patient group, a significant decrease in the sympathetic and parasympathetic components of HRV was observed following anesthesia (SD1: p = 0.019; SD2: p = 0.00027). No corresponding change in HRV was observed in controls. HRV parameters were modelled into a real-time graph. Using the monitoring technique developed, autonomic changes could be successfully visualized in real-time. This could provide the basis for a novel, fast and non-invasive method of autonomic assessment that can be delivered at the point of care.
