Sex differences in metabolic syndrome components in adolescent military dependents at high-risk for adult obesity.

BACKGROUND: Metabolic syndrome in adolescence has been associated with adverse cardiometabolic outcomes in adulthood. Preliminary data suggest that boys may have worsened metabolic syndrome components compared to girls. Yet, little is known about the physical health of military dependents, a potentially at-risk population. OBJECTIVE: Examine sex differences in metabolic syndrome components in a sample of adolescent military dependents. METHODS: Participants were adolescents (N = 139; 14.4 ± 1.6 years; 45.3% male; 41.0% non-Hispanic White, 19.4% non-Hispanic Black; BMI-z: 1.9 ± 0.4) at-risk for adult obesity and binge-eating disorder due to an age- and sex-adjusted BMI ≥85th percentile and loss-of-control eating and/or elevated anxiety. A multivariate analysis of covariance was conducted to compare objectively measured metabolic syndrome components across boys and girls. Covariates were age, race, loss-of-control eating status, anxiety symptoms, and BMI-z. RESULTS: Metabolic syndrome components differed by sex (P = .01). Boys had higher systolic blood pressure (P = .049), lower high-density lipoprotein cholesterol (P = .01), and higher glucose (P = .001) than girls. Waist circumference, diastolic blood pressure, and triglycerides did not differ between boys and girls (P > .05). CONCLUSIONS: Future research should prospectively examine these relationships into adulthood. If the current findings are supported, prevention programs should consider targeting cardiometabolic health particularly among male adolescent military dependents.

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

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.

Parental deployment and distress, and adolescent disordered eating in prevention-seeking military dependents.

OBJECTIVE: Parental military deployment can lead to stress in the family system due to concerns about the deployed service-member's safety and increased responsibilities for those not deployed. Parent-related stress can impact adolescent disordered eating. Given the important role that stress plays in disordered eating and obesity, it is crucial to understand the impacts of unique stressors to which vulnerable populations are exposed. METHOD: We studied 126 adolescent (14.3 ± 1.6 years; 59.5% girls; 44.4% non-Hispanic White; BMI-z, 1.91 ± .39) military dependents prior to entering an obesity and binge-eating disorder prevention trial. The Eating Disorder Examination was used to assess adolescent disordered eating. Parents self-reported their own distress and family deployment history that occurred during the adolescent's lifetime. RESULTS: Parental distress interacted with frequency of parental deployments such that for those with high parental distress, more frequent deployment was associated with greater adolescent shape and weight concerns (ß = .21, p = .012) and global eating pathology (ß = .18, p = .024). DISCUSSION: In this hypothesis-generating study, the combination of number of deployments and parental distress may be associated with disordered eating among adolescent military dependents seeking prevention of binge-eating disorder and adult obesity. If these preliminary findings are supported longitudinally, interventions to reduce parental stress related to deployment may be warranted to reduce disordered eating in adolescent dependents.

Associations between Family Weight-Based Teasing, Eating Pathology, and Psychosocial Functioning among Adolescent Military Dependents.

Weight-based teasing (WBT) by family members is commonly reported among youth and is associated with eating and mood-related psychopathology. Military dependents may be particularly vulnerable to family WBT and its sequelae due to factors associated with their parents' careers, such as weight and fitness standards and an emphasis on maintaining one's military appearance; however, no studies to date have examined family WBT and its associations within this population. Therefore, adolescent military dependents at-risk for adult obesity and binge-eating disorder were studied prior to entry in a weight gain prevention trial. Youth completed items from the Weight-Based Victimization Scale (to assess WBT by parents and/or siblings) and measures of psychosocial functioning, including the Beck Depression Inventory-II, The Rosenberg Self-Esteem Scale, and the Social Adjustment Scale. Eating pathology was assessed via the Eating Disorder Examination interview, and height and fasting weight were measured to calculate BMIz. Analyses of covariance, adjusting for relevant covariates including BMIz, were conducted to assess relationships between family WBT, eating pathology, and psychosocial functioning. Participants were 128 adolescent military dependents (mean age: 14.35 years old, 54% female, 42% non-Hispanic White, mean BMIz: 1.95). Nearly half the sample (47.7%) reported family WBT. Adjusting for covariates, including BMIz, family WBT was associated with greater eating pathology, poorer social functioning and self-esteem, and more depressive symptoms (ps ≤ 0.02). Among military dependents with overweight and obesity, family WBT is prevalent and may be linked with eating pathology and impaired psychosocial functioning; prospective research is needed to elucidate the temporal nature of these associations.

Sex differences in eating related behaviors and psychopathology among adolescent military dependents at risk for adult obesity and eating disorders.

Stressors unique to military families may place dependents of military service members of both sexes at high-risk for disordered-eating. Yet, there are no data examining sex-related differences in eating pathology and distress among this population. Therefore, we examined disordered-eating attitudes and associated psychosocial characteristics in adolescent military dependents at high-risk for both eating disorders and adult obesity (i.e., BMI ≥ 85th percentile and elevated anxiety symptoms and/or loss-of-control eating). One-hundred-twenty-five (55.2% female) adolescent (12-17 y) military dependents were studied prior to entry in an eating disorder and obesity prevention trial. Youth were administered the Eating Disorder Examination interview to determine disordered-eating attitudes, and completed questionnaires to assess self-esteem, social functioning, and depression. Girls and boys did not differ in BMIz (p = .66) or race/ethnicity (p = .997/p = .55). Adjusting for relevant covariates, girls and boys did not differ significantly with regard to disordered-eating global scores (p = .38), self-esteem (p = .23), or social functioning (p = .19). By contrast, girls reported significantly more symptoms of depression (p = .001). Adolescent male and female dependents at high-risk for eating disorders and adult obesity reported comparable levels of eating-related and psychosocial stress. Data are needed to elucidate how adolescent military dependents respond to intervention and whether sex moderates outcome.
