The younger the better: importance of age in treatment of childhood obesity.

Children living with obesity are prevalent worldwide. It is an established finding that many children who start a lifestyle intervention tend to leave prematurely. The aim of this study was to identify characteristics in children with obesity who prematurely leave a lifestyle intervention. The cohort study includes children living with obesity aged 4-17, treated in a Danish family-centered lifestyle intervention between 2014 and 2017. Data were collected from patient records. BMI-SDS was calculated using an external Danish reference population and multivariable regression analysis was used to answer the research question. Of the 159 children included, 64 children who left the intervention within the first 1.5 years were older compared to those who stayed in the intervention (10.2 years ± 2.9 vs 11.5 years ± 3.1, p = 0.005). Older participants (> 66.6th percentile) had a shorter treatment duration (489 days) compared to the youngest (190 days 95% CI: 60; 320, p = 0.005) and middle third (224 days 95% CI: 89; 358, p = 0.001). Additionally, an inverse association was found between duration of treatment and age at baseline (-31 days, 95% CI (-50; -13), p = 0.001).   Conclusion: The risk of leaving a lifestyle intervention prematurely was primarily dependent on the age of the participants, emphasizing the importance of including children early in lifestyle interventions. What is Known: • Lifestyle interventions for childhood obesity that are shorter in duration often lead to short-term weight reductions only. Limited knowledge exists on why some children prematurely leave these interventions. What is New: • This study observes a solid inverse correlation and association between age and time spent in the interventions, when treating childhood obesity. We hereby suggest age as an important determinant for the adherence to lifestyle interventions and emphasize the importance of treatment early in life.

The association between weight loss and long term development in quality-of-life among children living with obesity: a pragmatic descriptive intervention study.

BACKGROUND: Childhood obesity is associated with impaired Quality-of-Life (QoL), increased stigmatization and higher risk of development of depression compared to their peers. This report describes the long-term development in QoL for cohort of children with obesity after a sustainable weight reduction. METHODS: This pragmatic descriptive intervention study enrolled 120 children with obesity, age 5-17 years, in a multifactorial lifestyle intervention. The intervention was an across sectors collaboration between a department of pediatrics and community health care workers. QoL was assessed yearly throughout the intervention and evaluated by a 6-item Visual Analogue Scale (VAS). For analyzing changes in VAS, as function BMI-SDS, regression models were used, while ANOVA and Wilcoxon test were applied for normal and not-normal distributed data. 95% confidence interval not containing 0 and p-value < 0.05 was considered statistically significant. RESULTS: After 26.4 months (13.9 SD) an overall decrease in bullying (0.6 vs. 0.0 median) and motivation (10.0 vs. 9.6) was observed. QoL increased in children with a BMI-SDS reduction (0.65 (2.49 SD)) opposite children with no-change or increasing BMI-SDS who reported reduced QoL (-0.36 (1.55 SD) and -0.96 (2.27 SD)). A significant inverse relationship was observed for Joy of Life, QoL and body perception as a function of BMI-SDS per year. CONCLUSION: Weight reduction causes improvement in QoL for children with obesity and an inverse relationship for QoL and changing BMI-SDS / year was establish.

Sustainable weight loss over three years in children with obesity: a pragmatic family-centered lifestyle intervention.

INTRODUCTION: Childhood obesity has psychological consequences and increases the risk of continuous obesity into adulthood, associated with development of non-communicable disease (e.g. type 2 diabetes). Short-term weight loss intervention studies show good results but long-term studies are limited. METHODS: One hundred ninety-nine obese children (4-18 years of age), with a BMI-SDS (standard deviation score) above + 2 SDS were enrolled into a multifactorial family-centered lifestyle intervention study. The children had yearly visits in the outpatient clinic for anthropometrics, blood samples and DXA-scans, and 6-8 meeting with community health workers between these visits. The children followed the intervention up to 3 years. RESULTS: After a follow-up of 26.7 ± 17.5 months a reduction in BMI-SDS of - 0.25 SDS (p < 0.001) was observed. The 57 children who were adherent to the intervention for ≥ 2 years had significantly reduced BMI-SDS compared to the 142 children with shorter intervention (BMI-SDS: - 0.38 ± 0.67 vs. - 0.20 ± 0.50, p = 0.036). All weight loss was accompanied by decrease in fat mass and increase in muscle mass (p < 0.001). CONCLUSION: The intervention was found to induce long-term reduction in BMI-SDS in obese children, with beneficial change in body composition. Children who followed the intervention the longest had the greatest reduction in BMI-SDS. LEVEL OF EVIDENCE: Level III, longitudinal cohort study.

Uric Acid Is Elevated in Children With Obesity and Decreases After Weight Loss.

Introduction: Childhood obesity is an increasing condition associated with continuous obesity into adulthood and development of comorbidities. Adult studies show an association between serum uric acid (SUA) levels and body mass index (BMI). The aim of this retro perspective exploratory study was to investigate SUA in obese children and adolescents and the effects of a subsequent weight reduction. Materials and Methods: One hundred and seventy-one children (age 4-18), with obesity (i.e. BMI-SDS of +2 or higher) were included in a multifactorial lifestyle intervention. The children participating were annually measured for anthropometrics, blood samples and DEXA-scans for up to 3 years. Eighty-nine children were included for follow-up analysis. Results: After a follow-up of 20.7 ± 9.4 months a reduction in BMI-SDS of -0.34 ± 0.53 (p < 0.01) was observed. SUA was found to be positively associated with changes in BMI-SDS. SUA levels decreased in the 65 children who lost weight during the trial, conversely, SUA increased in the 23 children who gained weight during the trial (p < 0.01 between groups). Conclusion: SUA was found to correlate with measures of obesity and for the first time, this intervention demonstrates a positive relationship between SUA and weight reduction in children with obesity.

[Common variable immunodeficiency can present as a multisystemic disorder]. / Almindelig variabel immundefekt kan vise sig som en multisystemsygdom.

Common variable immunodeficiency is the second most common primary immunodeficiency with a prevalence of approx. 1/10.000-50.000. The clinical challenge is early diagnosis and efficient supportive treatment. The purpose of the present article is to focus on the complexity of the disease, including the risk of a long pre-diagnostic period and to focus on the sarcoidosis-like variant and the possible impact of immunoglobulin subclass deficiency.
