Youth internalizing symptoms, sleep-related problems, and disordered eating attitudes and behaviors: A moderated mediation analysis

Associations between disordered eating and body focused repetitive behaviors in college students

Objective: College students with disordered eating (DE) are at increased risk of body focused repetitive behaviors (BFRBs). Both DE and BFRBs are described as impulsive and compulsive. However, the associations of impulsive DE with impulsive BFRBs and compulsive DE with compulsive BFRBs have not been examined. Methods: 191 college-aged students completed a survey of BFRBs and DE. Results: Participants who reported hair pulling were twice as likely to report clinically significant DE than those who denied hair pulling (p = .022). Participants who endorsed distressing hair pulling (p = .026), skin picking (p = .052), and nail biting (p = .094) were twice as likely to report clinically significant DE than those who were not distressed by these behaviors. Evidence did not support the association of BFRBs and DE along an impulsive/compulsive continuum. Conclusions: Results suggest that BFRBs and DE often co-occur, and the role of impulsivity and compulsivity in these behaviors is complex.

Risk factors of disordered eating in adolescent girls from a community sample: a multidimensional approach

BACKGROUND

Eating disorders (ED) are severe, chronic, and complex in nature mental illnesses that are difficult to treat. One of the ways to stave off EDs is by screening among adolescents to preempt the development of clinical forms of ED in risk groups.

AIM

1) to investigate the prevalence of ED risk among adolescent girls and compare subgroups at high and low risk of ED; 2) to investigate using a multidimensional approach those variables that can interact with temperament and character traits to predict ED symptomatology.

METHODS

The cross-sectional observational self-report study of a community sample of adolescent girls 1217 years old (n=298; M=14.771.13) was carried out in the city of Ryazan, Russia. The Russian versions of Eating Attitudes Test and Cloningers Temperament and Character Inventory-Revised were used. In addition, an original questionnaire (Risk Factors of Eating Disorders) was developed. Regression models (to test for significant moderation) and path analysis (to test for significant mediations) were used.

RESULTS

Girls at risk of developing EDs are characterized by a heightened level of concern about weight and dissatisfaction with their body, tend to suffer from low self-directedness, higher novelty seeking and tendency to higher harm avoidance, display high alexithymia, experience self-distrust, negative emotionality and are dissatisfied with family relationships. They also suffer from low self-esteem and tend to be perfectionism and engage in risk behavior. Significant moderating effects were uncovered between the following ED risk factors: (1) self-distrust/risk behavior and BMI; (2) alexithymia/negative emotionality/self-esteem and cooperativeness; and (3) negative emotionality/risk behavior and self-transcendence. Family relationship dissatisfaction mediates the association between self-directedness/cooperativeness/self-transcendence and disordered eating.

CONCLUSION

There are various mutual influences between the numerous ED risk and prevention factors, which all together determine the paths between the predictors and final outcome.

Moderating Effects of Mindfulness in the Relation between Bullying Victimization and Sleep Disturbance in Chinese Children: Sex Differences

Bullying victimization is associated with sleep disturbance. The present study aimed to investigate the impact of bullying victimization on sleep disturbance, and the moderating effect of mindfulness on this association, also exploring differences across sex. A sample of 420 Chinese children (Mage = 9.60, SD age = 1.11, 48.10% girls) in grade 3 to grade 6 were recruited to complete the revised Bully/Victim Questionnaire, the Chinese version of Pittsburg Sleep Quality Index, the Child and Adolescent Mindfulness Measure, as well as the Family Affluence Scale. Results showed that bullying victimization was positively associated with sleep disturbance (β = 0.20, p < 0.001). And the effect of bullying victimization on sleep disturbance was moderated by mindfulness (β = -0.16, p < 0.001), and the effect was invalid for children with high mindfulness (β = 0.04, p > 0.05). Subgroup analyses indicated the buffering effect of mindfulness only existed among boys (β = -0.19, p < 0.01) but not girls (β = -0.11, p > 0.05), suggesting that mindfulness may buffer this association, mainly for boys.

Social and Individual Factors Associated with Eating Disorders in Young Athletes: Effects on Concentration and Fatigue

Eating disorders are a growing societal problem, especially among young people. This study aims to determine the individual and social factors that support and perpetuate the risk of eating disorders (ED) and their possible consequences on an individual's athletic and academic performances. The sample consisted of 395 athletes between 12 and 16 years of age (M = 14.07; SD = 1.35), of whom 142 (35.9%) were female, and 253 (64.1%) were male. A questionnaire was administered to collect information on sociodemographic data, body image, use of social networks, social relationships, sports practice, risk of developing ED, and academic and sports performance. In the resulting analysis, an initial cross-tabulation was carried out to observe the body distortion of the respondents as a function of BMI, followed by a linear regression to analyze the factors influencing the risk of suffering from ED. In addition, correlations were made to determine the relationship between the risk of manifesting ED and academic and sports performance. The main results show that 77.7% of the young athletes present a risk of ED (M = 13.3; DT = 3.33) due to a high body image distortion, which becomes the determining factor. In addition, relationships with family and friends have a significant influence on this. On the other hand, behaviors related with eating disorders affect concentration (r = -0.122; p = 0.01) and fatigue (r = -0.376; p < 0.01). For all these reasons, generating and promoting prevention and early detection guidelines during adolescence is necessary.

Parent-child relationship and problematic smartphone use among chinese adolescents: a moderated mediation model

To explore the influence and mechanism of parent-child relationship on adolescents' problematic smartphone use, a sample of 3355 Chinese adolescents (M age=16.93, SD = 0.49, range: 14-19 years old; 48% boys) is recruited to measure parent-child relationship, problematic smartphone use, personal growth initiative, and school belonging. The results are as follows. (1) After controlling for gender, age and time spent online per day, parent-child relationship is negatively correlated with problematic smartphone use, and the negative association between parent-child relationship and problematic smartphone use is mediated by the personal growth initiative. (2) The association between parent-child relationship and problematic smartphone use, the association between parent-child relationship and personal growth initiative, and the association between personal growth initiative and problematic smartphone use are all moderated by school belonging and are stronger in adolescents with a high level of school belonging. The present study highlights the mediating role of personal growth initiative and the moderating role of school belonging in the association between parent-child relationship and problematic smartphone use. This study also contributes to a better understanding of the effects, paths, and conditions of parent-child relationship on the problematic smartphone use of adolescents and provides constructive suggestions for preventing adolescents' problematic smartphone use in the mobile Internet era.

Potential eating disorder exhibited with daytime functional vulnerabilities associated with sleep problems in Japanese adolescents: A cross-sectional study

OBJECTIVES

Eating disorders (ED) are serious psychiatric disorders that affect individuals, especially adolescents. It has been suggested that nonclinical ED-like characteristics are related to sleep problems. We conducted a survey of Japanese adolescents to investigate this claim.

METHOD

In this cross-sectional study, 398 adolescents aged 12-18 years responded to a self-administered questionnaire survey. We used the Eating Attitudes Test-26 (EAT-26) and the Athens Insomnia Scale (AIS) to measure potential ED and sleep problems, respectively.

RESULTS

Adolescents with potential ED had significantly higher daytime functional vulnerability potentially associated with sleep problems than those without ED. In particular, problems with a sense of well-being and physical and mental functioning during the day were significant. In contrast, no significant associations were found between potential ED and sleep initiation, awakenings during the night, early morning awakening, total sleep duration, or overall quality of sleep. Finally, nocturnal and daytime sleep scores were significantly associated with dieting, bulimia, and oral control EAT-26 subscores.

DISCUSSION

Participants with possible ED experienced problems related to well-being and mental and physical functioning, which are indicators of daytime functional vulnerability potentially associated with sleep problems. Further, adolescents with more severe ED characteristics are more likely to have a higher degree of daytime psychological vulnerability potentially attributable to sleep problems. The study suggested that professionals treating adolescent mental health issues need an approach that comprehensively integrates both sleep problems and potential ED.

Poor sleep and adolescent obesity risk: a narrative review of potential mechanisms

Poor sleep is related to increased obesity risk in adolescents, though the mechanisms of this relationship are unclear. This paper presents a conceptual framework of the various pathways that have been proposed to drive this relationship. In this framework, increased food reward, emotional reactivity, decreased inhibitory control, metabolic disturbances, poorer dietary quality, and disrupted meal timings may increase the likelihood of increasing overall energy intake. This paper further notes how poor sleep increases sedentary behavior and screen time, which likely limits overall energy expenditure. The model posits that these mechanisms result in an imbalance of energy intake and expenditure following poor sleep, intensifying the overall risk for obesity. Increases in food reward processes, decreases in insulin sensitivity, disrupted meal timing, and increases in sedentary behavior seem to be the most compelling mechanisms linking poor sleep with increased obesity risk in adolescents. Future directions and clinical implications of this framework are discussed.

Health Outcomes Associated With Internalizing Problems in Early Childhood and Adolescence

Physical and mental health problems are becoming more common among the general population. Studies examining mental and physical health often indicate that mental illness early in life is associated with more detrimental health outcomes later. However, additional work is needed to better identity which psychological problems may contribute to poorer health outcomes. Given recent increases in childhood anxiety and depression specifically, it is beneficial to further investigate the relationship between internalizing problems, both early and later in life, and related health problems. Furthermore, little work has focused on studying internalizing problems in children as young as preschool-aged. Therefore, the current project used a longitudinal design to assess the effects of preschool and adolescent internalizing problems on health-related problems in adolescence. We analyzed data from 70 youth (47% male) who had been tested in our lab when they were 5 years old and then were administered questionnaires over a telephone interview when they were adolescents, between the ages of 12 and 20 years old. We used multi-informant measures, including parent-report at age 5 and youth-report at follow-up, 7 to 15 years later. Parents reported on children's internalizing behavior problems and negative emotionality (NE). Youth reported on their own internalizing behavior problems as well as health problems, physical activity, and overeating behaviors. Path modeling was used to examine predictions of internalizing and health behaviors. At age 5, parent-reported NE and internalizing problems were related, in addition to 5-year-old internalizing predicting health problems and overeating at follow-up. At follow-up, youth-reported internalizing was positively related to health problems and negatively related to physical activity, suggesting some similarities and differences between parent and youth responses. Additionally, girls reported significantly higher rates of internalizing and health problems at follow-up. These results indicate a significant relationship between preschool-aged and adolescent internalizing problems and related health outcomes experienced in adolescence.

Lack of implementation of eating disorder education and prevention programs in high schools: Data from incoming college freshmen

The purpose of this study was to examine the implementation of eating disorder education and prevention programs in high schools retrospectively, as reported by incoming college freshmen, exploring whether characteristics of the school influenced implementation. The sample, 169 first-year students from a public university, participated in an online survey inquiring about exposure to programs and high school characteristics. Results demonstrated few students exposed to any eating disorder programming (29.0%), with no students reporting exposure to prevention programming. Furthermore, there were no significant differences in the implementation based on school characteristics, suggesting that this is a universal issue across high schools.
