“…Lastly, we found that depression and anxiety could positively predict disordered eating in the lockdown group. This was consistent with many previous studies from different countries, showing that poor mental health due to lockdown would lead to unhealthy and even dysfunctional eating [ 37 – 39 ].…”

Objective The rapid spread of the Omicron variant of COVID-19 in China had resulted in campus lockdown in many universities since February 2022, profoundly affecting students’ daily lives. Campus lockdown conditions differ considerably from home quarantine, so that the eating patterns of university students may be different. Thus, the current study aimed to: (1) investigate university students’ eating patterns during campus lockdown; (2) identify factors associated with their disordered eating. Method An online survey about recent life changes, disordered eating, stress, depression, and anxiety was carried out from April 8th to May 16th, 2022. A total of 2541 responses from 29 provinces/cities of China were received. Results 2213 participants were included in the main analysis, and other 86 participants were analyzed separately as a subgroup due to their diagnosis of eating disorder. Participants who were undergoing campus lockdown (the lockdown group) showed less disordered eating than those who had never been in campus lockdown (the never-lockdown group), as well as those who had experienced campus lockdown before (the once-lockdown group). However, they perceived more stress and felt more depressed. Being female, higher BMI, gaining weight, increasing exercise, spending more time on social media, higher level of depression and anxiety were all related to disordered eating in the lockdown group. Conclusions Disordered eating among Chinese university students was less prevalent during campus lockdown due to the strict and regular diet. However, there is a potential risk of “revenge eating” after campus lockdown ends. Thus, there should be further tracking and related prevention. Level of evidence IV, uncontrolled trials without any interventions.

“…Patients who had AN or BN were recruited from the ED outpatient clinic in Seoul Paik Hospital during the same period. Parts of the study were previously published (23)(24)(25). The groups were defined as underweight (UW, BMI; body mass index < 18 kg/m 2 ), normal-weight (NW, 18 kg/m 2 ≤ BMI < 25 kg/m 2 ), and overweight or obese (OW, BMI ≥ 25 kg/m 2 ) according to the conventional World Health Organization (WHO) classification (26) instead of the Asia-Pacific regional guidelines (27), and AN and BN based on the Diagnostic and Statistical Manuals of Mental Disorders, Fifth Edition (12).…”

BackgroundExtreme weight conditions in young women are associated with adverse health outcomes. Closely linked with extreme weight status, eating disorders (EDs) are associated with several medical complications and high mortality rates.ObjectiveThe study aimed to investigate the biochemical, hematologic, and skeletal features of young Korean women with underweight (UW) and overweight/obesity (OW) conditions, and patients with anorexia nervosa (AN) and bulimia nervosa (BN) compared to women with normal-weight (NW).MethodA total of 808 women (mean age 22.3 ± 3.4 years) were recruited for the study, including 144 with UW status [body mass index (BMI) < 18.5 kg/m2], 364 with NW, 137 with OW or obesity (27 with obesity; BMI ≥ 25 kg/m2), 63 patients with anorexia nervosa (AN), and 100 with bulimia nervosa (BN). We measured blood pressure and performed biochemical, hematologic and bone mineral density (BMD) evaluations at the lumbar and femoral neck.ResultsBlood pressure and triiodothyronine levels were found to be lower in both ED groups and higher in the OW group, but no difference in the UW group, compared to the NW group. The aminotransferases and total cholesterol levels were higher in the ED and OW groups, compared to the NW group. Blood cell counts were decreased in the AN group, while increased in the OW group, compared to the NW group. Blood urea nitrogen was elevated in both ED groups. The UW and AN groups had lower BMD, whereas the OW group had higher BMD, compared to the NW group.ConclusionOur findings suggested that both ED groups were associated with decreases in the resting energy expenditure. OW status was associated with a risk of metabolic syndrome, and UW status with lower BMD in young women. Overall, the medical parameters in Korean patients with ED were similar to the patterns reported in Western samples in previous studies, with few exceptions such as potassium level in BN.
