肥胖儿童胰岛素抵抗、骨代谢与骨龄超前的 关联

Association between Insulin Resistance, Bone Metabolism, and Advanced Bone Age in Obese Children

摘要: 学龄期儿童中肥胖问题突出，为探讨肥胖儿童胰岛素抵抗、骨代谢与骨龄超前的关联机制，本研究通过系统检索国内外相关文献，采用文献综述方法，分析肥胖儿童胰岛素抵抗机制及其对骨代谢的影响，介绍骨龄超前评估方法，阐述肥胖与骨龄超前的关联，并开展相关临床案例与数据分析，探讨三者综合关联。发现肥胖儿童胰岛素抵抗显著，通过多种途径影响骨代谢平衡，导致骨形成减少、骨吸收增加，面临更高骨质疏松和骨折风险；肥胖与骨龄超前关联紧密，通过内分泌激素紊乱等机制加速骨龄；三者相互作用，胰岛素抵抗影响骨代谢促进骨龄超前，骨龄超前又反馈影响胰岛素敏感性和骨代谢，且遗传、营养和运动等因素也影响骨龄超前。肥胖儿童应采取生活方式调整、药物治疗及定期监测的综合干预策略，未来需多学科合作深入探究分子机制，开展大规模研究验证干预措施。

Abstract: Obesity is a prominent issue among school-aged children. To explore the mechanisms linking obesity, insulin resistance, and advanced bone age, this study systematically reviewed domestic and international literature using a literature review approach. It analyzed the mechanisms of insulin resistance in obese children and its impact on bone metabolism, introduced advanced bone age assessment methods, and examined the association between obesity and advanced bone age. Clinical cases and data analysis were conducted to investigate the comprehensive interrelationships among these factors. The findings revealed that obese children exhibit significant insulin resistance, which disrupts bone metabolism balance through multiple pathways, leading to reduced bone formation and increased bone resorption, thereby elevating the risk of osteoporosis and fractures. Obesity is closely linked to advanced bone age, accelerating bone development via mechanisms such as endocrine hormone disorders. These three factors interact synergistically: insulin resistance affects bone metabolism, promoting advanced bone age, which in turn influences insulin sensitivity and bone metabolism. Genetic, nutritional, and exercise factors also impact advanced bone age. A comprehensive intervention strategy involving lifestyle adjustments, pharmacological treatment, and regular monitoring is recommended for obese children. Future research should involve multidisciplinary collaboration to delve into molecular mechanisms and conduct large-scale studies to validate intervention measures.
