Abstract：
UNASSIGNED: To determine whether socio-demographic and preoperative clinical factors contribute to the percent total body weight loss (%TBWL) after bariatric surgery (BS).
UNASSIGNED: BS is the most effective long-term treatment for medically complicated obesity. More information is needed about the factors that contribute to postoperative %TBWL in large and ethnically diverse cohorts.
UNASSIGNED: This retrospective study conducted in the Kaiser Permanente Northern California region included 7698 patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between January 2009 and March 2015. Trajectory analyses were conducted from 5-year follow-up data to assign patients to \"low,\" \"average,\" or \"high\" postoperative %TBWL groups. We then evaluated whether age, sex, race/ethnicity, neighborhood deprivation index and preoperative body mass index (BMI)/weight loss, diabetes, hypertension, and sleep apnea contributed to postoperative %TBWL using logistic regression models.
UNASSIGNED: Of 7698 patients (83.2% women), 48.6% underwent a RYGB and 51.4% underwent a SG. Postoperative %TBWL trajectories over 5 years were obtained in 6229 (81%) of 7698 eligible patients. About 27.8% and 29.3% of patients followed the \"low\" postoperative %TBWL trajectory, for RYGB and SG, respectively. Men, older patients, and Asian, Black, and Hispanic/Latino patients were more likely to be classified in the low postoperative %TBWL group. Patients showing lower postoperative %TBWL had a lower preoperative BMI (but lost less weight before surgery) and were more likely to have preoperative comorbidities.
UNASSIGNED: This study confirms and extends prior findings of the effects of several demographic and preoperative clinical factors on postoperative weight loss. Findings could improve the support of patients to achieve desired surgical outcomes.

摘要：
■确定社会人口统计学和术前临床因素是否有助于减肥手术（BS）后的总体重减轻百分比（％TBWL）。
■BS是医学上复杂的肥胖最有效的长期治疗方法。在大型和种族不同的队列中，需要更多有关导致术后TBWL％的因素的信息。
这项在北加利福尼亚KaiserPermanente地区进行的回顾性研究包括了在2009年1月至2015年3月期间接受Roux-en-Y胃旁路术(RYGB)或袖状胃切除术(SG)的7698例患者。从5年的随访数据中进行了轨迹分析，以将患者分配到“低，\"\"平均值,\"或\"高\"术后%TBWL组。然后我们评估了年龄，性别,种族/民族,邻里剥夺指数和术前体重指数（BMI）/体重减轻，糖尿病,高血压,使用逻辑回归模型，睡眠呼吸暂停占术后TBWL的百分比。
■在7698名患者中（83.2%为女性），48.6%接受了RYGB，51.4%接受了SG。在7698例符合条件的患者中，6229例（81％）获得了5年的术后TBWL轨迹。大约27.8%和29.3%的患者遵循“低”术后TBWL%轨迹，对于RYGB和SG，分别。男人,老年患者,亚洲人,黑色,西班牙裔/拉丁裔患者更有可能被归类为术后TBWL%低的组。术后TBWL%较低的患者术前BMI较低（但手术前体重减轻较少），更有可能在术前合并症。
■本研究证实并扩展了一些人口统计学和术前临床因素对术后体重减轻的影响。研究结果可以提高患者的支持，以达到预期的手术效果。
