BackgroundWeight regain is a common problem following weight loss intervention, with most people who seek treatment for obesity able to lose weight, but few able to sustain the changes in behavior required to prevent subsequent weight regain. The identification of factors that predict which patients will successfully maintain weight loss or who are at risk of weight regain after weight loss intervention is necessary to improve the current weight maintenance strategies. The aim of the present study is identify factors associated with successful weight loss maintenance by women with overweight or obesity who completed group cognitive behavioral treatment (CBT) for weight loss.MethodsNinety women with overweight or obesity completed a 7-month weight loss intervention. The data of 86 who completed follow-up surveys 12 and 24 months after the end of the treatment was analyzed. Depression, anxiety, binge eating, food addiction, and eating behaviors were assessed before and after the weight loss intervention. Participants who lost at least 10% of their initial weight during the weight loss intervention and had maintained the loss at the month 24 follow-up were defined as successful.ResultsThe intervention was successful for 27 participants (31.3%) and unsuccessful for 59 (68.6%). Multiple logistic regression analysis extracted larger weight reduction during the weight loss intervention, a lower disinhibition score, and a low food addiction score at the end of the weight loss intervention as associated with successful weight loss maintenance.ConclusionThe results suggest that larger weight reduction during the weight loss intervention and lower levels of disinhibition and food addiction at the end of the weight loss intervention predicted successful weight loss maintenance.Trial registrationTrial registry name: Development and validation of effective treatments of weight loss and weight-loss maintenance using cognitive behavioral therapy for obese patients.Registration ID: UMIN000006803Registered 1 January 2012.URL: https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000008052
<b><i>Objective:</i></b> Current evidence suggests that obesity is associated with alteration of sweet taste perception. The purpose of this study was to determine if nonsurgical cognitive behavioral therapy (CBT)-based weight loss can cause a change in sweet taste perception. <b><i>Methods:</i></b> This case-control study consisted of 51 women aged 21–64 years. Twenty-seven with obesity or overweight were assigned to an obesity (OB) group (BMI: 29.8 ± 0.5 kg/m<sup>2</sup>) and 24 to a normal control (NC) group (BMI: 20.9 ± 0.3 kg/m<sup>2</sup>). The OB group underwent a 30-week weight loss intervention using CBT-based group therapy. The results of measurement of detection threshold, suprathreshold perceived intensity, preference, and palatability, elements of sweet taste perception, were compared before and after the intervention. Psychological variables and appetite-related hormonal levels were measured. <b><i>Results:</i></b> Twenty-three patients and 22 controls completed the study. The OB group showed a 14.6% weight loss after the intervention. At baseline, the OB group preferred significantly higher sucrose concentrations than did the NC group; however, this difference was no longer significant after intervention. In the OB group, persistent pleasure and reduced desire for other taste, measured by repeated exposure to sweetness, normalized after weight loss to levels comparable to those seen in the NC group. No significant difference in discriminative perception of the threshold concentration or the suprathreshold sensory value was found between the two groups before or after intervention. A significant correlation was found between the basal preferred sucrose concentration and the serum leptin level of the OB group after adjusting for confounding factors, such as BMI, depressive symptom score, and trait-anxiety scores. <b><i>Conclusions:</i></b> Weight loss induced by CBT-based nonsurgical intervention resulted in the normalization of the sucrose preference and palatability of women with obesity. Leptin activity may be associated with the altered sweet taste preference of people with obesity.
Background Doctors treating COVID-19 are under extreme stress. It was reported that healthcare workers providing palliative care could present elevated levels of compassion fatigue. We herein report a case if the attending doctor of severe COVID-19 cases who felt extreme psychological difficulty and suffered from compassion fatigue. Case presentation A 29-year-old female doctor presented with anxiety and insomnia. Her stress from overwork was exacerbated during the treatment of two related COVID-19 patients, a 47-year-old man with COVID-19 and his 76-year-old mother, who suffered acute stress disorder after the death of her son. The mother first refused treatment, but with psychiatric intervention she was able to recover and be discharged. In the course of these cases of COVID-19, their attending physician felt psychological distress and presented with insomnia and anticipatory anxiety due to the poor prognosis of the mother. After being presented with a systematic approach to improve her work situation by the hospital executive staff and undergoing psychotherapy for compassion fatigue, she recovered and was able to return to work. Conclusions We report a physician in charge of severe cases of COVID-19, who suffered an adverse impact on her mental health. Excessively empathic engagement in the care of patients who do not survive and their relatives provides high risk for compassion fatigue. The stress-related distress of HCWs should be more widely recognized in order to improve support systems for them.
This study aimed to identify occupational stress, psychosomatic symptoms, psychological distress, and their correlations among frontline nurses during and after the first peak of the coronavirus disease 2019 (COVID-19) outbreak in Japan. Sixteen frontline nurses, aged 25 to 52 years, working in a ward with COVID-19 patients participated in this study. Two months after the peak of the first wave of the COVID-19 outbreak in Japan, the COVID-19-related occupational stress scale (COS; questionnaire items: fear of infection and increased workload) and physical symptom scale (PS; questionnaire items: gastrointestinal symptoms, pain, appetite loss, and insomnia) were assessed. The degree of general psychological distress was evaluated using the 6-item Kessler Scale (K6). Simultaneously, participants were asked to recall their condition during the peak period of the first wave and rate it using the same scale. K6 was positively correlated with COS and PS during the peak period (rs = 0.574, P = .020 and rs = 0.587, P = .017, respectively). Increased workload was positively correlated with the K6 score both during and after the peak period (rs = 0.869, P < .001 and rs = 0.732, P = <.001, respectively) and was positively correlated with insomnia during the peak period (rs = 0.498, P < .05). The COS, PS, and K6 scores during the peak period were significantly higher than those after the peak period. Psychological distress at the peak was associated with PS and occupational stress. An increased workload during peak periods can cause psychological distress and insomnia. The occupational stress, PS, and psychological distress of nurses working in COVID-19 wards improved after the peak of COVID-19.
