Abstract

Background: It is crucial to understand weight trends in patients undergoing total hip arthroplasty (THA).

Objective: To evaluate preoperative and postoperative weight trends for patients undergoing primary THA and factors associated with clinically significant weight change.

Methods: A prospective cohort who underwent primary unilateral THA (n= 3,011) at a tertiary healthcare system (January 2016 to December 2019) were included in the study. The primary outcomes were clinically significant weight change (> 5% change in body mass index [BMI]) during the one-year preoperative and one-year postoperative periods.

Results: Preoperatively, 66.6% maintained a stable weight, 16.0% gained and 17.4% lost weight, respectively. Postoperatively, 64.0% maintained a stable weight, while 22.6% gained and 13.4% lost weight, respectively. Female sex, Black race, obesity, higher Charlson Comorbidity Index (CCI) scores, and older age were associated with preoperative weight loss. Female sex, obesity, higher CCI scores, and Medicare insurance were associated with postoperative weight loss. Preoperative weight loss was associated with postoperative weight gain (OR = 3.37 [CI: 2.67 to 4.25]; p< 0.001), and preoperative weight gain was associated with postoperative weight loss (OR = 1.74 [CI: 1.30 to 2.3]; p< 0.001).

Conclusion: Most patients maintained a stable BMI one-year before and one-year after THA. Several factors are associated with weight loss before and after THA. Preoperative weight changes were associated with a reciprocal rebound in BMI post-operatively.

全髋关节置换术前后体重变化的纵向分析：体重趋势、模式和预测因素。

背景：了解接受全髋关节置换术（THA）患者的体重趋势至关重要：了解接受全髋关节置换术（THA）患者的体重趋势至关重要：目的：评估接受全髋关节置换术（THA）的患者术前和术后的体重趋势，以及与临床显著体重变化相关的因素：研究纳入了在一家三级医疗保健系统（2016 年 1 月至 2019 年 12 月）接受初级单侧 THA 的前瞻性队列（n= 3,011 人）。主要结果为术前一年和术后一年期间临床上明显的体重变化（体重指数[BMI]变化>5%）：结果：术前，66.6%的患者体重保持稳定，16.0%的患者体重增加，17.4%的患者体重减轻。术后，64.0%的人体重保持稳定，22.6%的人体重增加，13.4%的人体重减轻。女性、黑人、肥胖、夏尔森综合症指数（CCI）评分较高和年龄较大与术前体重减轻有关。女性性别、肥胖、CCI 评分较高和医疗保险与术后体重下降有关。术前体重减轻与术后体重增加有关（OR = 3.37 [CI：2.67 至 4.25]；P< 0.001），术前体重增加与术后体重减轻有关（OR = 1.74 [CI：1.30 至 2.3]；P< 0.001）：结论：大多数患者在THA术前一年和术后一年的体重指数保持稳定。有几个因素与 THA 手术前后体重下降有关。术前体重的变化与术后体重指数的反弹相互关联。

期刊介绍： Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered: 1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables. 2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words. Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics. 4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors. 5.Letters to the Editors: Discussions or short statements (not indexed).
