Of these, 159 (36.8%) youths were characterized by extreme obesity.

The aim of the present study was to investigate long-term weight development following children participating in one of two pragmatic family-centered lifestyle interventions for children with obesity. Methods This real-life observational study included Danish children 4-17 years of age classified as having obesity. Data from 2010-2020, from two community-based family-centered lifestyle interventions (designated hereafter as the Aarhus- and the Randers-intervention) were merged with national registers and routine health check-ups, including height and weight. Adjusted mixed effect models were used to model changes in Body Mass Index (BMI) z-score. We performed exploratory analyses of the development in BMI z-score within stratified subgroups of children treated in the interventions before investigating potential effect modifications induced by sex, age, family structure, socioeconomic or immigration status. Results With a median follow-up of 2.8 years (interquartile range: 1.3;4.8), 703 children participated in an intervention (445 the Aarhus-intervention; 258 the Randers-intervention) and 2,337 children were not invited to participate (no-intervention). Children in both interventions experienced a comparable reduction in BMI z-scores during the first 6 months compared to the no-intervention group (Aarhus-intervention: -0.12 SD/year and Randers-intervention: -0.25 SD/year). Only children in the Randers-intervention reduced their BMI z-score throughout follow-up (Aarhus-intervention vs. no-intervention: 0.01 SD/year; CI:-0.01;0.04; Randers-intervention vs. no-intervention: -0.05 SD/year; CI:-0.08;-0.02). In a subgroup comparisons combining the two interventions, family income below the median (-0.05 SD/year, CI: -0.02;-0.09), immigrant background (0.04 SD/year, CI: 0.00; 0.07), or receiving intervention less than one year (0.04 SD/year, CI: 0.00;0.08) were associated with a yearly change in BMI z-score. In addition, effect modification analyses did not observe any interaction by sex, age, family structure, socioeconomic or immigration. Conclusions Although the more dynamic intervention with longer duration obtained and sustained a minor reduction in BMI z-score, the clinical impact may only be modest. However, this effect may at the best be only modest and still not effective enough to induce a long-term beneficial development in BMI in children with obesity.","PeriodicalId":19414,"journal":{"name":"Obesity Facts","volume":"66 1","pages":"1-19"},"PeriodicalIF":3.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the complications of extreme obesity is massive localized lymphedema (MLL), due to compromised lymphatic drainage. There is a lack of literature guiding the medical management of these conditions.CASE PRESENTATIONWe present a 43-year-old male who was admitted to our specialized obesity center for weight management. His initial weight was 255 kg and BMI, 93.7 kg/m2. He suffered from massive multifocal lymphedema of his left leg. He was bedridden due to his condition and malnourished, as shown by multiple vitamin deficiencies. The patient received care from our multidisciplinary team including nurses, dieticians, physical therapists, and psychologists. Treatment with semaglutide was started in hospital and continued at home. The maximal dose used was 1 mg/week but decreased during follow-up to 0.25 mg/week to avoid malnutrition. Protein and nutritional supplements were added. At 28 weeks of therapy, the patient had lost 40 kg or 15.7% of his total body weight (TBW). His lymphedema decreased; he had lost at least 16 cm of his left thigh circumference. He was able to walk again and regain autonomy of his daily activities of living.CONCLUSIONSemaglutide can be effective in patients with extreme obesity, with the support of a multidisciplinary team in a specialized obesity center. It can also help decrease MLL.
