CMAJ:肥胖是一种慢性病!加拿大肥胖管理指南

2020-08-15 xujing 中国循环杂志

近日,加拿大发布肥胖管理指南,指出肥胖管理的第一步就是要认识到肥胖是一种普遍、复杂、进行性和复发性疾病,是以不正常或过多的体脂为特征的有损健康的慢性病。

30年来,全球肥胖的流行呈升高态势,肥胖已经成为全球一个主要的公共卫生问题。近日,加拿大发布肥胖管理指南,指出肥胖管理的第一步就是要认识到肥胖是一种普遍、复杂、进行性和复发性疾病,是以不正常或过多的体脂为特征的有损健康的慢性病。

本指南建议肥胖管理重在改善以患者为中心的健康状况,而不是单纯的减肥。

肥胖管理应基于慢性病管理循证原则为基础解决肥胖的根源,不是简单的“少吃,多动”方案。

要避免歧视,因为歧视导致发病率和死亡率增加,且这与体重或体重指数无关。

肥胖管理的评估环节重点关注患者的健康行为,并针对体重增加的根本原因有的放矢。

指南还指出,测量身高、体重、腰围和体重指数是常规体检项目。

对于BMI增加(25~34.9 kg/m2)的人,建议应定期测量腰围,以识别内脏肥胖和肥胖相关疾病高危者。

肥胖的原始原因有生物因素,社会因素和个人生活经历、心理因素等。指南建议要全面了解肥胖者的这些情况,明确肥胖的根本原因,制定个性化的减重方案。

还建议测量血压、血糖及血脂,以确定心脏代谢风险,如有必要,还建议筛查非酒精性脂肪性肝病。

共识指出,所有肥胖者都能从健康均衡的饮食以及体力活动中获益。减肥和体重维持需要长期减少热量摄入。

长期坚持符合个人偏好的健康饮食模式,同时满足营养需求和治疗目标,是管理健康和体重的重要一环。

医学营养治疗是慢性病管理的基础。然而,医学营养疗法不应孤立地用于肥胖症的治疗,因为长期维持减肥可能是困难的,因为大脑中的代偿机制通过增加饥饿感促进热量摄入,最终导致体重增加。

相反,医学营养疗法应结合其他干预措施(心理干预、药物治疗、外科手术),进而为肥胖者量身定制减肥方案。

通过改变健康行为实现体重减轻3%~5%,可以显着改善肥胖相关的合并症。

体重降低多少在个体之间有很大的差异,这取决于生理和心理因素,而不仅仅是个人的努力。

指南指出,保持健康行为但体重仍保持不变,可被称为“最佳体重”,这可能不是体重指数量表中的“理想”体重。

达到一个“理想”的体重指数可能是非常困难的,不仅仅是通过行为改变就能实现的,可考虑药物或者手术治疗。

对BMI≥30 kg/m2或BMI≥27 kg/m2并伴有肥胖相关并发症的肥胖者,指南建议辅助药物治疗减肥,包括利拉鲁肽3mg,纳曲酮-安非他酮联合用药和奥利司他。

对于BMI≥40 kg/m2或BMI≥35 kg/m2且至少有1种肥胖相关疾病,可考虑减肥手术。
