Concordantly, studies reported an increasing trend in the prevalence and severity of binge eating and emotional eating symptoms. Aims: To estimate the prevalence and severity rates of binge eating and emotional eating symptoms during the Covid-19 pandemic through systematic review with meta-analysis. Methods: Pre-registered systematic review with meta-analysis (Prospero ID: CRD42022316105). Results: Systematic searches in PubMed and Web of Science (final search date 19th of March, 2022) yielded 27 eligible studies on changes in binge eating and emotional eating prevalence and severity rates during the Covid-19 outbreak (total N = 22.029). An overall increase in the elicited and exacerbated binge eating and emotional eating symptoms during the Covid-19 pandemic was observed (number of studies (k) = 14, r = 0.27, 95% CIs = 0.059 to 0.478). Furthermore, overall 7% of participants reported increases in pooled binge eating and emotional eating behaviours. Conclusions: Our data show a significant increase in the prevalence and severity rates of binge eating and emotional eating during the Covid-19 outbreak. This increase may be expected due to raised emotions of stress, loss of control, fear, ineffectiveness, and boredom during the pandemic. Public health policies and intervention programs for preventing and treating binge eating and emotional eating symptoms should be considered during confinement or related circumstances.Show less

It is important to find out, because CA already predicts more risk for psychological problems such as depression. CA can also have an impact on the stress hormone cortisol, which can lead to less or more depressive symptoms. Research is needed to find out if CA and cortisol can be of risk for developing depression after lockdown due to COVID-19 or if adolescents will be resilient to these kinds of stressors. Method: The sample consisted of 89 adolescents with a history of CA, recruited through an earlier study named Resilience after Individual Stress Exposure (RAISE). The adolescents filled in two questionnaires: Childhood Trauma Questionnaire (CTQ) and Mood and feelings questionnaire (MFQ). They also performed an fMRI stress task (MIST) where prior to this test blood was contained for measurement of cortisol. After the first lockdown of COVID-19 the MFQ was filled in again. Results: The results stated that after the lockdown the depression symptoms were increased (Z = 4,122, p < .001). But threat and deprivation (both CA) were not predictors of cortisol (threat: b = -.214, t (87) = -200, p = .842, deprivation: b = .316, t (87) = .2523, p = .801). Cortisol did not have mediation effect between threat/deprivation and changes in depression symptoms (threat: 95% CI [-.017,.026], deprivation: 95% CI [-.037,.031]). And lastly only threat was a predictor for changes in depression symptoms (b = .255, t (87) = 2.3863, p = .019). Discussion: This research has proved that there is an increase in depressive symptoms after the first lockdown in April of the year 2020. Secondly, history of threat and deprivation are not predictors of cortisollevels in the adolescence. Third, cortisol did not play a mediation role between CA (threat/deprivation) and depressive symptoms. Lastly, threat predicts depressive symptoms after the lockdown. In future similar situations, to prevent development of (more) depressive symptoms that may lead to depression disorder, extra support for adolescents, especially with history of threat, is needed.Show less

Not much was known about the effect of lockdowns on social anxiety in adolescents. Aim. This study aimed to gain insight into changes in social anxiety before and after a school closure associated with COVID-19 lockdown and its relation to the experience of the lockdown in Dutch adolescents aged 12-15 years. Methods. A total of 188 adolescents (M = 13.48, SD = 0.81) completed self-report measures of social anxiety on March 2020 (T1). In September 2020 (T2) they completed the same self-report measures of social anxiety, enjoyment of the lockdown, and Worries about COVID-19. Results. Adolescents with average or high symptoms of social anxiety before the first school closure showed a significant reduction in social anxiety symptoms after the first school closure. The expected positive association between social anxiety before and after school closure was moderated by Enjoying the lockdown but not gender. Furthermore, higher symptoms of social anxiety before the first school closure were associated with higher levels of enjoying the lockdown. Conclusion. Results indicated that adolescents with moderate to high social anxiety symptoms and who enjoyed the lockdown and associated consequences such as less face-to-face interaction were most at-risk of reporting higher symptoms of social anxiety once the schools had reopened.Show less
