Abstract

Introduction

Limited insight exists into the weight development in children with obesity not receiving obesity treatment.

Methods

This cohort study included 467 Danish children aged 5–10 years with obesity (iso-BMI >30 kg/m²) not receiving treatment. Data from mandatory health check-ups on school-children's height and weight (converted to BMI z-scores) were merged with the Danish National Registries. A multivariable logistic regression weighted for the duration of follow-up was used to estimate odds ratios (OR) for normalization of BMI (iso-BMI 18.5–25 kg/m²) and obesity remission (iso-BMI 18.5–30 kg/m²).

Results

During a median follow-up of more than 6 years, 7.9% of the children normalized their BMI, while 45.4% obtained obesity remission. BMI z-score at inclusion acted as a strong inverse predictor for normalizing BMI (OR 0.14 per one-unit SD, CI: 0.03–0.53) and for obesity remission (OR 0.17 per one-unit SD, CI: 0.08–0.37). No other significant predictors were observed in the weighted multivariable models.

Conclusion

Higher BMI z-scores inversely predict normalizing BMI and achieving obesity remission in untreated children. Given that many children naturally achieve obesity remission or weight normalization, resources should focus on understanding barriers of obesity maintenance and to develop effective strategies for those who do not experience improvement.

未经治疗的肥胖儿童体重发展：一项丹麦长期随访队列研究。

对未接受肥胖治疗的肥胖儿童体重发展的了解有限。方法：该队列研究纳入467名5-10岁未接受治疗的丹麦肥胖儿童（iso-BMI >30 kg/m2）。强制性健康检查的学龄儿童身高和体重数据（转换为BMI z分数）与丹麦国家登记处合并。采用随访时间加权的多变量logistic回归来估计BMI正常化（iso-BMI 18.5-25 kg/m2）和肥胖缓解（iso-BMI 18.5-30 kg/m2）的比值比（OR）。结果：在中位超过6年的随访期间，7.9%的儿童BMI恢复正常，45.4%的儿童肥胖得到缓解。纳入时的BMI z评分是BMI正常化（OR 0.14 /单位SD， CI: 0.03-0.53）和肥胖缓解（OR 0.17 /单位SD， CI: 0.08-0.37）的一个强有力的反向预测因子。在加权多变量模型中没有观察到其他显著的预测因子。结论：较高的BMI z分数与未治疗儿童BMI正常化和肥胖缓解呈负相关。鉴于许多儿童自然达到肥胖缓解或体重正常化，资源应该集中在了解肥胖维持的障碍，并为那些没有经历改善的儿童制定有效的策略。

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
