Relationship between Mental Health and Emotional Eating during the COVID-19 Pandemic: A Systematic Review.

Obesity is one of the most dangerous epidemics of the 21st century. In 2019, the COVID-19 pandemic began and caused many deaths among patients with obesity with and without complications. Simultaneously, the lockdown related to the COVID-19 pandemic caused a host of emotional problems including anxiety, depression, and sleep disturbances. Many people began to cope with their emotions by increasing food (emotional eating) and alcohol consumption and in combination with decreased physical activity, promoted the development of overweight and obesity. Emotional eating, also known as stress eating, is defined as the propensity to eat in response to positive and negative emotions and not physical need. It should be noted that emotional eating may be the first step in the development of binge eating disorder and its extreme subtypes such as food addiction. Interestingly in some post-bariatric surgery patients, an increased frequency of addictive disorders has been observed, for example food addiction replaced by alcohol addiction called: "cross addiction" or "addiction transfer". This data indicates that obesity should be treated as a psychosomatic disease, in the development of which external factors causing the formation of negative emotions may play a significant role. Currently, one of these factors is the COVID-19 pandemic. This manuscript discusses the relationships between the COVID-19 pandemic and development of emotional eating as well as potential implications of the viral pandemic on the obesity pandemic, and the need to change the approach to the treatment of obesity in the future.

Persisting olfactory dysfunction in post-COVID-19 is associated with gustatory impairment: Results from chemosensitive testing eight months after the acute infection.

Olfactory and gustatory disorders are prominent symptoms of acute COVID-19. Although both senses recover in many patients within weeks to months, persistency has been described in up to 60%. However up to now most reports on the course of chemosensitive disorders after COVID-19 are not based on psychophysical testing but only on subjective patients' ratings. In this study we assessed both olfaction and gustation using psychophysical tests eight months after COVID-19. Validated psychophysical testing revealed hyposmia in 18% and hypogeusia in even 32% of 303 included patients. This shows that olfactory and especially gustatory disorders have to be seen as important chronic symptoms post-COVID-19. The high prevalence of gustatory dysfunction indicates that gustatory function does not recover or might even deteriorate in the months following the acute infection.

"Are people thinking I'm a vector because I'm fat?": Cisgender experiences of body, eating, and identity during COVID-19.

While a range of studies have shown the negative impact of COVID-19 on disordered eating and body image, few have engaged with how identity and social context interact with these domains. The current study used inductive codebook thematic analysis to understand experiences of body and eating during the pandemic among a diverse (sub)clinical sample of individuals with self-reported disordered eating. We interviewed 31 cisgender participants (18/31 Black Indigenous People of Color (BIPOC), 24/31 women) with a history of disordered eating (diagnosed and undiagnosed). Five themes were identified: Body Surveillance and Dissatisfaction, Movement and Intake Fixation, Food Scarcity and Resource Concerns, Changes in Visibility of Body and Eating, and Bodies Are Vulnerable. We examined the extent to which themes pertained to certain identities over others. Notably, BIPOC, large-bodied, queer participants more commonly spoke to body vulnerability than White, small/medium-bodied, straight participants. BIPOC and large-bodied participants also particularly spoke to feeling relief from discrimination as social distancing and mask wearing reduced their public visibility. Participants related these themes to changed body and eating experiences that spanned distress and resilience. Our analysis offers insight into multifaceted and contextual impacts of COVID-19 on experiences of body, eating, and identity.

Comparison of Food-Based and Music-Based Regulatory Strategies for (Un)Healthy Eating, Depression, Anxiety and Stress.

There are many ways to regulate emotions. People use both adaptive (e.g., regulation by music) and maladaptive (e.g., regulation by food) strategies to do this. We hypothesized that participants with a high level of food-based regulatory strategies and a low level of music-based regulatory strategies (a group with the least adaptive form of emotion regulation) would have significantly greater levels of unhealthy eating behaviours, depression, anxiety and stress, as well as a significantly lower level of healthy eating behaviours than those with a low level of food-based regulatory strategies and a high level of music-based regulatory strategies (a group with the greatest adaptive form of emotion regulation). Participants (N = 410; Mage = 31.77, SD = 13.53) completed: the Brief Music in Mood Regulation Scale, the Emotional Overeating Questionnaire, the Healthy and Unhealthy Eating Behavior Scale, the Depression, Anxiety and Stress Scale and a socio-demographic survey. The four clusters were identified: (a) Cluster 1 (N = 148): low food-based regulatory strategies and high music-based regulatory strategies; (b) Cluster 2 (N = 42): high food-based regulatory strategies and high music-based regulatory strategies; (c) Cluster 3 (N = 70): high food-based regulatory strategies and low music-based regulatory strategies; (d) Cluster 4 (N = 150): low food-based regulatory strategies and low music-based regulatory strategies. Overall, our outcomes partially support our hypothesis, as higher levels of unhealthy eating behaviours, depression, anxiety and stress were observed in participants with high food-based and low music-based regulatory strategies as compared with adults with low food-based and high music-based regulatory strategies. To sum up, the results obtained indicate that during the COVID-19 pandemic the group of people regulating their emotional state and unhealthy eating predominantly with food is potentially characterized by worse functioning than the group of people regulating with music. Therefore, it can be concluded that people who regulate their functioning using food should be included in preventive measures by specialists. During the visit, psychologists and primary care physicians can ask patients about their daily strategies and based on this information specialists can estimate the potential risk of developing high levels of stress and anxiety, depressive disorders and unhealthy eating habits and provide specific (match) intervention.
