Study design:

Cohort study 

研究目的:

1.主要目的:在实现临床意义减重(幅度≥5%)的肥胖人群中,量化减重速度与各身体成分变化率之间的独立关联。 2.次要目的:量化比较减重后不同身体成分(宏观及微观)变化率的差异,系统评估生活方式管理对该人群身体成分的影响。  

Objectives of Study:

1. Primary Objective: To quantify the independent association between the rate of weight loss and the rates of change in various body composition measures among individuals with obesity who achieved clinically meaningful weight loss (≥5%). 2. Secondary Objective: To compare and quantify the differences in change rates among different body composition components (both at the macro and micro levels) following weight loss, thereby systematically evaluating the impact of lifestyle management on body composition in this population.

5.Participation in other weight loss programs or surgeries within the past 3 months;
6.Presence of severe psychiatric or behavioral disorders that, in the investigator’s judgment, could interfere with study procedures;
7.Any other condition deemed by the investigator as unsuitable for study participation;

测量指标:

Outcomes:

指标中文名:

减重速度

指标类型:

主要指标

Outcome:

Weight Loss Rate

Type:

Primary indicator

测量时间点:

终点

测量方法:

减重速度指基于体脂秤数据计算的,计算公式为:减重速度=减重幅度(%)/减重时长(周),其中减重幅度=(基线体重-终点体重)/基线体重×100%

Measure time point of outcome:

Endpoint

Measure method:

The weight loss rate was calculated based on body weight data obtained from the body fat scale. The calculation formula was as follows: Weight Loss Rate = Weight Loss Percentage (%) / Weight Loss Period (weeks), where Weight Loss Percentage = (Baseline Weight ? Final Weight) / Baseline Weight × 100%.

指标中文名:

体成分变化率

指标类型:

主要指标

Outcome:

Body Composition Change Rates

Type:

Primary indicator

测量时间点:

终点

测量方法:

对体脂肪量、体脂肪率、去脂体重、身体水分量、肌肉量、蛋白质、无机盐,根据体脂秤数据,统一按以下公式计算变化率:身体成分变化率=(终点值-基线值)/基线值×100%

Measure time point of outcome:

Endpoint

Measure method:

The change rates for the seven body composition parameters—fat mass (FM), body fat percentage (FM%), fat-free mass (FFM), total body water (TBW), skeletal muscle mass (SMM), body protein, and bone mineral content (BMC)—were calculated from the body fat scale data using the following formula: Component Change Rate (%) = (Post-value ? Baseline value) / Baseline value × 100%

指标中文名:

身体成分

指标类型:

次要指标

Outcome:

Body Composition Parameters

Type:

Secondary indicator

测量时间点:

基线、每次随访、终点

测量方法:

使用体脂秤(生物电阻抗分析法)测量数据,包括体重、身体质量指数(BMI)、体脂肪量、体脂肪率、去脂体重、身体水分量、肌肉量、蛋白质、无机盐、基础代谢率。

Measure time point of outcome:

Baseline, Each Follow-up, Endpoint

Measure method:

Body composition was assessed using bioelectrical impedance analysis (BIA) via a body fat scale. The following parameters were measured or derived: body weight, body mass index (BMI), fat mass (FM), body fat percentage (FM%), fat-free mass (FFM), total body water (TBW), skeletal muscle mass (SMM), body protein, bone mineral content (BMC), and basal metabolic rate.
