People with physical disabilities (PWD) have an increased risk of obesity and related comorbidities compared with people without physical disabilities (PWoD). Previously identified contributors to weight loss maintenance pose challenges to PWD. However, it is not known if PWD experience less success in weight management.Six hundred and nine participants in the International Weight Control Registry (IWCR) were eligible for this analysis (PWD, n = 174; PWoD, n = 435). Self‐reported weight history metrics were compared using general linear models. Perceived weight history category was compared using Chi‐squared tests. Importance of diet and physical activity strategies for weight management were compared using Wilcoxon rank‐signed tests.PWD reported higher current body mass index (BMI) (36.1 ± 0.7 vs. 31.0 ± 0.5; p < 0.0001) and more weight loss attempts (9.1 ± 0.7 vs. 7.1 ± 0.4; p = 0.01) than PWoD. Current weight loss percentage (PWD 13.0 ± 1.0; PWoD, 13.0 ± 0.6; p = 0.97) and weight loss category (χ2 [3, N = 609] = 2.9057, p = 0.41) did not differ between the groups. There were no differences in any weight strategy between PWD who were successful and those who regained.PWD and PWoD in the IWCR achieved similar levels of weight maintenance success. However, higher BMI and more weight loss attempts suggest that PWD may face challenges with weight management. More research is needed to identify strategies leading to success for PWD.
与非肢体残疾人(PWoD)相比,肢体残疾人(PWD)患肥胖症及相关并发症的风险更高。之前发现的影响减肥效果的因素给残疾人带来了挑战。国际体重控制注册中心(IWCR)的 69 名参与者符合本次分析的条件(残疾人,n = 174;非肢体残疾人,n = 435)。使用一般线性模型对自我报告的体重史指标进行比较。使用卡方检验比较感知体重史类别。与残疾人相比,残疾人报告的当前体重指数(BMI)(36.1 ± 0.7 vs. 31.0 ± 0.5; p < 0.0001)和减肥尝试次数(9.1 ± 0.7 vs. 7.1 ± 0.4; p = 0.01)更高。目前的减重百分比(PWD 13.0 ± 1.0;PWoD 13.0 ± 0.6;p = 0.97)和减重类别(χ2 [3, N = 609] = 2.9057, p = 0.41)在两组之间没有差异。成功减重的残疾人和体重反弹的残疾人在任何体重策略上都没有差异。然而,较高的体重指数和更多的减肥尝试表明,残疾人在体重管理方面可能面临挑战。需要开展更多研究,以确定帮助残疾人取得成功的策略。

There is substantial inter‐individual variability in response to weight loss interventions and emerging evidence suggests that weight loss during the early weeks of an intervention may be predictive of longer‐term weight loss. This secondary analysis of data from a commercial program therefore examined 1) the associations between early weight loss (i.e., week 4) with final visit weight loss and duration on the program, and 2) other predictors of lower weight loss at final visit.Client charts of adults with overweight or obesity (N = 748) were analyzed. Clients were stratified into categories of weight loss at the week 4 (< and ≥2%, 3% and 4%) and final visits (< and ≥5% and 10%). Multivariate logistic regression was used to assess predictors of <5% and <10% final visit weight loss.The odds ratios for losing <5% or <10% of weight at the final visit were higher (49.0 (95% CI: 13.84, 173.63) and 20.1 (95% CI: 6.96, 58.06)) for clients who lost <2% or <3% compared to those who lost ≥2% or ≥3% at week 4. Other predictors of not losing a clinically relevant amount of weight included female sex, use of higher calorie meal plans and shorter time in the program, among others. Those who lost ≥2% at week 4 also had a significantly greater percent program completion (109.2 ± 75.2% vs. 82.3 ± 82.4, p < 0.01) compared with those who did not meet the 2% threshold.Lower 4‐week weight loss was identified as a strong predictor of not losing a clinically relevant amount of weight. These results may be useful for the early identification of individuals who can be targeted for additional counseling and support to aid in attaining weight loss goals.
个体间对减肥干预措施的反应存在很大差异,而新出现的证据表明,干预措施初期几周的体重减轻情况可能预示着长期的体重减轻情况。因此,本研究对一项商业项目的数据进行了二次分析,研究内容包括:1)早期体重减轻(即第 4 周)与最终就诊体重减轻和项目持续时间之间的关联;2)最终就诊体重减轻较低的其他预测因素。分析了超重或肥胖成人的客户病历(N = 748),并将客户在第 4 周(< 和≥2%、3% 和 4%)和最终访问(< 和≥5% 和 10%)时的体重减轻情况进行了分层。与第4周体重下降≥2%或≥3%的客户相比,第4周体重下降<2%或<3%的客户最终就诊时体重下降<5%或<10%的几率比较大(49.0(95% CI:13.84,173.63)和20.1(95% CI:6.96,58.06))。其他预测体重未达到临床相关水平的因素还包括女性性别、使用高热量膳食计划以及参与该计划的时间较短等。与未达到 2% 临界值的人相比,第 4 周体重下降≥2% 的人的计划完成率也明显更高(109.2 ± 75.2% vs. 82.3 ± 82.4,p < 0.01)。这些结果可能有助于及早确定哪些人可以成为额外咨询和支持的目标,以帮助他们实现减肥目标。

Weight change in chronic kidney disease: Association with mortality and kidney function 慢性肾脏病患者的体重变化:体重变化:与死亡率和肾功能的关系

Excess body weight is a risk factor for the progression of chronic kidney disease (CKD), but weight loss in CKD has been associated with higher mortality. Consequently, blanket weight loss recommendations in this population are controversial. Little data is available on the patterns of weight‐change in CKD. The authors aimed to describe weight‐changes in moderate/severe CKD and explore associations with mortality and renal endpoints in patients with overweight and obesity.Non‐dialysis Canberra Hospital patients with estimated glomerular filtration (eGFR) < 60 mL/min/1.73 m2 and body mass index (BMI) ≥25 kg/m2 were followed for up to 5.5 years. Weight‐change ≥5% was considered clinically significant. The renal endpoint was defined as the commencement of dialysis or transplant or a ≥40% fall in eGFR. Relationships between weight‐change in the first year of follow‐up and mortality or the renal endpoint were assessed using Cox‐regression.Three hundred ten patients (median age 75, median BMI 31 kg/m2) were identified. 68% had Stage‐4 CKD at baseline. Over 4.4‐years median follow‐up, 128 died and 140 had significant weight‐change. During the first year of follow‐up, 42 patients lost and 23 gained ≥5% body weight, of whom only 3 had intentionally lost weight. On multivariate regression, significant weight loss/gain at 1‐year was associated with 2.74 (p < 0.0005) and 2.67 (p = 0.003) hazard of subsequent death and with 2.51 (p = 0.004) and 2.20 (p = 0.05) hazard of the renal endpoint respectively. There was no association between baseline eGFR and subsequent weight change.Patients with moderate/severe CKD experience significant weight‐change, but this has no relationship to baseline kidney function. Significant weight‐change is associated with higher subsequent mortality and loss of kidney function, but this association is likely significantly affected by confounding.
体重过重是慢性肾脏病(CKD)恶化的一个危险因素,但慢性肾脏病患者体重减轻与死亡率升高有关。因此,针对这一人群的全面减肥建议存在争议。有关 CKD 患者体重变化模式的数据很少。作者对估计肾小球滤过率(eGFR)< 60 mL/min/1.73 m2、体重指数(BMI)≥25 kg/m2的堪培拉医院非透析患者进行了长达 5.5 年的随访,旨在描述中度/重度 CKD 患者的体重变化,并探讨其与超重和肥胖患者的死亡率和肾脏终点的关系。体重变化≥5%被认为具有临床意义。肾脏终点定义为开始透析或移植或 eGFR 下降≥40%。采用 Cox 回归法评估随访第一年体重变化与死亡率或肾脏终点之间的关系。在基线时,68%的患者为四期 CKD。中位随访时间为 4.4 年,其中 128 人死亡,140 人体重发生显著变化。在随访的第一年中,42 名患者体重下降,23 名患者体重增加≥5%,其中只有 3 名患者是故意减肥。多变量回归结果显示,1年内体重明显减轻/增加分别与2.74(p < 0.0005)和2.67(p = 0.003)的后续死亡风险以及2.51(p = 0.004)和2.20(p = 0.05)的肾脏终点风险相关。中度/重度慢性肾功能衰竭患者的体重会发生显著变化,但这与基线肾功能没有关系。显著的体重变化与较高的后续死亡率和肾功能丧失有关,但这种关联很可能受到混杂因素的显著影响。

Very low‐calorie diets (VLCDs) employing total meal replacement (TMR) offer substantial short‐term weight loss. Concurrently, anti‐obesity medications (AOMs) have shown promise as adjunctive treatments when combined with VLCDs.This study aimed to investigate the impact of adjuvant AOMs on weight loss and weight regain within a comprehensive lifestyle program.This is a retrospective study of patients with obesity enrolled in VLCD/TMR programs,  specifically the OPTIFAST program.Data from 206 patients (68% women, mean age 52.39 ± 13.05 years, BMI 41.71 ± 7.04 kg/m2) were analyzed. Of these, 139 received no AOM (AOM‐), while 67 received AOMs (AOM+). Total body weight loss percentages (TWL%) at 6 and 18 months were −17.87% ± 7.02 and −12.10% ± 11.56, respectively. There was no significant difference in 6‐month weight loss between the AOM groups. However, the AOM + group exhibited lower weight regain (3.29 kg ± 10.19 vs. 7.61 kg ± 11.96; p = 0.006) and weight regain percentage (WR%) (31.5% ± 68.7 vs. 52.16% ± 64.4; p = 0.04) compared with the AOM‐ group.The findings highlighted the potential of AOMs and VLCD/TMR as effective strategies for long‐term weight management in individuals with obesity.
采用全餐替代(TMR)的超低卡路里饮食(VLCD)可在短期内大幅减轻体重。本研究旨在调查在一项综合生活方式计划中,辅助性抗肥胖药物(AOMs)对体重减轻和体重反弹的影响。本研究是一项回顾性研究,研究对象是参加 VLCD/TMR 计划(特别是 OPTIFAST 计划)的肥胖症患者。其中,139 人未接受 AOM(AOM-),67 人接受了 AOM(AOM+)。6个月和18个月的总体重减轻率(TWL%)分别为-17.87% ± 7.02和-12.10% ± 11.56。AOM组与AOM+组在6个月的体重减轻率上没有明显差异。然而,与AOM-组相比,AOM +组的体重反弹率(3.29 kg ± 10.19 vs. 7.61 kg ± 11.96; p = 0.006)和体重反弹百分比(WR%)(31.5% ± 68.7 vs. 52.16% ± 64.4; p = 0.04)较低。
