Smartphone Use

Background: Sleep problems and eating disorders (EDs) are both serious public health concerns often seen in young adults. Yet, the underlying mechanisms for such associations are largely unknown. This study aims to examine potential serial multiple mediation effects of problematic smartphone use (PSU) and psychological distress (i.e., depressive and anxiety symptoms) in the relationship between sleep quality and disordered eating behaviors/attitudes (DEBs).Methods: A total of 4,325 students from two Tibet universities in China (2,657 females and 1,668 males) completed an online survey that included the following measurements: Eating Attitude Test-26 for disordered eating behaviors/attitudes, the Chinese Version of Pittsburgh Sleep Quality Index (CPSQI), Smartphone Addiction Scale—Short Version (SAS-SV) for problematic smartphone use, Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) for psychological distress.Results: While the direct path linking sleep quality and DEBs was not found to be significant (Standardized β = 0.006, 95% CI = −0.0667~0.0970), both PSU (Standardized β = 0.016, 95% CI = 0.0256~0.0591) and anxiety symptoms (Standardized β = 0.014, 95% CI = 0.0203~0.0526) may mediate a link between sleep quality and DEBs; serial multiple mediation analysis revealed that a serial indirect pathway of “sleep quality -> PSU -> anxiety symptoms -> DEBs” existed(Standardized β = 0.001, 95% CI = 0.0002~0.0012). Similarly, while the direct path linking sleep quality and DEBs was not found to be significant (Standardized β = 0.006, 95% CI = −0.0667~0.0970), both PSU (Standardized β = 0.020, 95% CI = 0.0337~0.0692) and depressive symptoms (Standardized β = 0.015, 95% CI = 0.0139~0.0652) may mediate a link between sleep quality and DEBs; serial multiple mediation analysis revealed that a serial indirect pathway of “sleep quality -> PSU -> depressive symptoms -> DEBs” existed (Standardized β = 0.001, 95% CI = 0.0006~0.0038).Conclusions: Psychological and behavioral factors may comprehensively work together, leading to flow-on effects from sleep problems to disordered eating behaviors among university students. Appropriate interventions that target problematic smartphone use could thus potentially reduce anxiety and depression levels, which in turn will provide a buffer against the negative impact of poor sleep quality on eating disorder symptoms.

Abstract Objective: This study aims to explore associations between disordered eating behaviors in adults during the COVID-19 lockdown period, and the experienced psychosocial impact of the COVID-19 pandemic, depressive symptomatology, anxiety/stress levels.Methods: This was a community-based cross-sectional study assessing 254 Portuguese adults (82.7% women; 35.82 ±11.82 years) one week after the end of the mandatory COVID-19 lockdown in Portugal. An online survey was conducted to evaluate psychological distress, disordered eating, and psychosocial impact of the COVID-19 pandemic. Pearson correlations and Structural Equation Modeling (SEM) were performed.Results: Participants reported the presence of meal skipping (52.8%), grazing eating behavior (80.9%), overeating (81.0%), loss of control over eating (47.2%), and binge eating episodes (39.2%) during lockdown. Uncontrolled and emotional eating were significantly correlated with the psychosocial impact of COVID-19 pandemic, depression, anxiety, and stress levels. SEM analyses indicated that the relationship between experienced psychosocial impact of COVID-19 pandemic on disordered eating behaviors was mediated through psychological distress experienced (CMIN/DF= 1.499, CFI = .99, RMSEA = .045).Conclusions: The psychosocial impact of the COVID-19 pandemic crisis may lead to disordered eating, and this relation may occur through the elevation of psychological distress. These findings inform about clinical targets for preventive interventions to promote disordered eating in a community sample during potential similar future situations.

Mediation Models

We investigated potential mechanisms that may explain the relationship between weight stigma and disordered eating behaviors, using 2 mediation models. In the first model we hypothesized that the relationship between weight stigma and disordered eating behaviors would be mediated by weight bias internalization, and jointly mediated by both weight bias internalization and core self-evaluation. In the alternative model we hypothesized that this relationship would be mediated by core self-evaluation, and jointly mediated by both core selfevaluation and weight bias internalization. Participants were 421 primary and secondary school students (aged 9–14 years) representing various weight categories, who responded to items about their weight stigma, weight bias internalization, core self-evaluation, and disordered eating behaviors. Results show that the 2 mediation models had a good fit to the data. Thus, improving core self-evaluation and reducing weight bias internalization appear to be significant for treating disordered eating behaviors in preadolescents and adolescents.
