Examination of the Interpersonal Model With Adolescent Military Dependents at High Risk for Adult Obesity.

ABSTRACT: OBJECTIVE:Adolescent military dependents may be at higher risk for psychosocial stressors and disordered eating compared with civilian youths, but the mechanisms underlying these risks are unclear. Interpersonal theory proposes that difficult relationships lead to negative affect, thereby promoting emotional eating, which has been linked to and predictive of disordered eating. The interpersonal model may have particular relevance for understanding disordered eating among adolescent military dependents, given the unique stressors related to their parents' careers. This study aimed to examine the premise of the interpersonal model (that negative emotions mediate the association between multiple aspects of social functioning and emotional eating) among a cohort of adolescent military dependents. METHODS:Military dependents (N=136; 56% female, mean±SD age=14±2 years, body mass index adjusted for age and sex [BMIz]=2.0±0.4) at risk for adult obesity and binge eating disorder, as indicated by reported loss-of-control eating and/or anxiety symptoms, were assessed prior to participation in a study of excess weight-gain prevention. Bootstrapped mediation analyses were conducted to examine depressive symptoms as a potential mediator of the relationship between social functioning and emotional eating. Analyses were adjusted for age, sex, race-ethnicity, BMIz, and presence of reported loss-of-control eating and anxiety. RESULTS:Depressive symptoms were a significant mediator of the relationship between multiple domains of social functioning, including loneliness, social adjustment related to family and friends, attachment to father and peers, and emotional eating (p<0.05). CONCLUSIONS:The interpersonal model may contribute to our understanding of excess weight gain and binge eating disorder among adolescent military dependents. Prospective data are needed to determine the utility of interpersonal theory in predicting treatment response and outcomes among this population.

Project description:PurposeEvidence suggests that difficulties identifying and describing one's feelings, core components of alexithymia, are associated with attitudinal and behavioral symptoms of disordered eating; depressive symptoms also may underlie these associations. Specifically, research indicates that alexithymia is positively related to depressive symptoms, which in turn may promote both disordered-eating attitudes and certain disinhibited-eating behaviors (e.g., emotional eating). Findings also suggest that military-dependent youth with high weight may exhibit elevated depressive symptoms and disordered eating. As such, understanding associations among alexithymia, depressive symptoms, and disordered eating is particularly relevant for this vulnerable population.MethodsWe examined 149 adolescent military dependents (14.4 ± 1.6y; 55.0% female; 20.0% non-Hispanic Black; BMIz: 1.9 ± 0.4) at high risk for binge-eating disorder and obesity in adulthood. Participants completed questionnaires assessing two components of alexithymia (difficulty identifying feelings [DIF] and difficulty describing feelings [DDF]), depressive symptoms, emotional eating, and trait anxiety; disordered-eating attitudes were assessed via semi-structured interview.ResultsA series of regression-based models examined indirect relationships of DIF and DDF with disordered-eating attitudes and emotional eating through depressive symptoms. Bootstrapped 95% confidence intervals revealed a significant indirect path from each of the alexithymia components to disordered-eating attitudes via depressive symptoms; indirect paths to emotional eating were non-significant.ConclusionResults support the salience of depressive symptoms in the relationship between alexithymia and disordered-eating attitudes. Future research should utilize prospective designs and explore direct and indirect associations of alexithymia with other disordered-eating behaviors.Level of evidenceLevel III, evidence obtained from a well-designed cohort study.

Project description:IntroductionAdolescent military-dependents face unique psychosocial stressors due to their parents' careers, suggesting they may be particularly vulnerable to excess weight gain and symptoms of depression and anxiety. Despite these risk factors, there is a lack of tested preventative interventions for these youths. Given the transient nature of military family deployments, research may be hindered due to difficulty in collecting long-term prospective outcome data, particularly measured height and weight. The primary aim of this study was to examine the feasibility and acceptability of collecting body mass index (BMI, kg/m2) outcome data up to 2 years following a randomized controlled pilot trial of an adapted interpersonal psychotherapy (IPT) program aimed at preventing excess weight gain and improving psychological functioning for adolescent military-dependents. In exploratory analyses, patterns in body composition over time were examined.Materials and methodsTwenty-seven adolescent military-dependent girls (baseline: Mage: 14.4 ± 1.6 years; MBMI: 30.7 ± 4.9 kg/m2; MBMI-z: 1.9 ± 0.4) participated in this study. After a baseline assessment, utilizing a computerized program to create a randomization string, girls were assigned to either an IPT or a health education (HE) program. Participants completed three follow-up visits (posttreatment, 1-year follow-up, and 2-year follow-up). Girls completed a Treatment Acceptability Questionnaire at posttreatment; at all time points, height and fasting weight were collected. For the primary aim, Fisher's exact tests examined the rate of obtained follow-up data and lost to follow-up status between the two groups, Mann-Whitney U tests examined the session attendance between groups, and treatment acceptability ratings were compared between the two groups at posttreatment using an independent samples t-test. For the exploratory aim, one-way analyses of covariance (ANCOVAs) examined the group differences in BMI at each time point, adjusting for baseline values, and paired samples t-tests examined the within-group differences at each time point relative to baseline. Using imputed data in the full intent-to-treat sample, mixed model ANCOVAs were conducted to examine the group differences over time.ResultsAcross both groups, girls attended an average of 72.0% of sessions. At least partial data were collected at posttreatment, 1-year follow-up, and 2-year follow-up for 96.3%, 85.2%, and 74.1% of the participants, respectively. There were no significant group differences in follow-up data collection rates, follow-up status, number of sessions attended, or treatment acceptability. BMI-z stabilized across groups, and there were no group differences in BMI-z. In adjusted ANCOVA models with imputed data, no significant group-by-time effects emerged.ConclusionsFor this randomized controlled prevention trial, long-term outcome data collection of measured BMI was possible in adolescent military-dependents and IPT was an acceptable and feasible intervention. An adequately powered trial is required to assess the efficacy of this intervention among military-dependents for obesity prevention and improvements in BMI.
