JAMA:饮食结合运动可治疗膝骨关节炎带来的疼痛

2013-09-27 佚名 EurekAlert!中文版

据9月25日发表在《美国医学会杂志》上的一则研究披露,在罹患膝骨关节炎的超重及肥胖的成年人中,强化的饮食与运动相结合的疗法可在18个月后带来比单独饮食疗法和单独运动疗法更少的膝部疼痛及较好的膝部功能。 根据文章的背景资料:“骨关节炎(OA)是老年人慢性残疾的首要原因。膝OA是活动能力依赖性及生活品质降低的最常见的原因,而肥胖症是膝部OA的一个主要的风险因子。目前对膝部OA的治疗是不足的;在接受药

据9月25日发表在《美国医学会杂志》上的一则研究披露,在罹患膝骨关节炎的超重及肥胖的成年人中,强化的饮食与运动相结合的疗法可在18个月后带来比单独饮食疗法和单独运动疗法更少的膝部疼痛及较好的膝部功能。

根据文章的背景资料:“骨关节炎(OA)是老年人慢性残疾的首要原因。膝OA是活动能力依赖性及生活品质降低的最常见的原因,而肥胖症是膝部OA的一个主要的风险因子。目前对膝部OA的治疗是不足的;在接受药物治疗的患者中,只有大约一半的人感到疼痛减轻了30%,但他们常常没有得到功能的改善。”【原文下载

北卡罗莱纳州温斯顿 - 塞勒姆维克森林大学的Stephen P. Messier, Ph.D.及其同事开展了一项研究,旨在确认在与运动相结合或者在不与运动相结合的情况下,通过饮食而使体重减轻10%或更多是否可比单独运动更能降低关节负荷及炎症并改善临床转归。这一随机化的试验是在2006年7月至2011年4月开展的。这项饮食及运动的干预是基于治疗中心的,而运动组有着过渡至基于家庭的计划的选项。这项研究包括了454名超重及肥胖的居住在社区的老年人(其年龄在55岁或以上,他们的身体质量指数为27-41),他们具有疼痛性及经过放射学检查证实了的膝OA。该项干预是由强化的饮食诱发的体重减轻与运动相结合、强化的饮食诱发的体重减轻或运动组成的。

在参与者中,有399人(88%)完成了这项研究(并接受了为期18个月的随访)。两组之间的保持没有差别。该研究的发现包括:

◆ 饮食及运动组与饮食组的平均体重减轻幅度比运动组更大;

◆ 当与运动组进行比较时,饮食与运动组有着较少的膝部疼痛、较好的功能、更快的行走速度及更好的与身体健康相关的生活品质;

◆ 饮食加运动组及运动组的参与者比那些在运动组的参与者有着较大幅的白细胞介素6(一种对炎症的检测)水平的减少;

◆ 那些饮食组的参与者有着比运动组参与者更大幅的膝部压力的减少。

文章的作者写道:“骨关节炎及其它的肥胖相关性疾病对美国的医疗保健系统造成了巨大的物力与财力负担。估计有9700万名超重及肥胖的美国人罹患多种威胁生命及包括OA在内的致残性疾病的风险显著增高。这一试验的发现提示,强化的体重减轻可能兼具消炎及生物力学方面的裨益;当减肥与运动结合时,病人能够安全地做到平均的长期体重减轻10%以上,并会比另外两种单独的干预取得更大的相关性症状改善。”
