We conducted a pilot randomised controlled trial comparing the effects of a dietetic intervention to usual care, in 40 individuals with a body mass index >30kg/m(2) undergoing total joint replacement (TJR). The dietetic weight loss intervention comprised at least four sessions with an Accredited Practising Dietitian. At 12 months, the usual care group gained weight, +2.01kg (6.45), whereas the treatment group lost weight, -3.38kg (6.62), (p=0.015). Percentage weight change in the treatment group was -3.20% (5.24), compared to +1.67% (6.16) for the usual care group (p=0.015) and more participants in the intervention group (45%) lost ≥5% of their baseline weight (13%), (p=0.057). Physical health scores were also better for the intervention group [42.2 (11.80); 32.86 (9.91), p=0.014]. Findings suggest that a structured dietitian-led weight loss intervention in patients undergoing TJR is more effective in achieving weight loss than usual care, and can result in improved physical health scores at 12 months post-TJR.
我们开展了一项初步随机对照试验，比较饮食干预与常规护理对40名体重指数>30kg/m²且正在接受全关节置换术（TJR）的个体的影响。饮食减肥干预包括至少与一名注册营养师进行四次会诊。在12个月时，常规护理组体重增加，增加了2.01kg（6.45），而治疗组体重减轻，减轻了3.38kg（6.62），（p = 0.015）。治疗组的体重变化百分比为-3.20%（5.24），而常规护理组为+1.67%（6.16），（p = 0.015），并且干预组中更多参与者（45%）体重减轻了≥其基线体重的5%（13%），（p = 0.057）。干预组的身体健康评分也更高[42.2（11.80）；32.86（9.91），p = 0.014]。研究结果表明，由营养师主导的结构化减肥干预对接受TJR的患者而言，在实现体重减轻方面比常规护理更有效，并且在TJR后12个月可使身体健康评分得到改善。
