研究目的:

本研究拟通过随机、双盲、安慰剂对照试验研究设计,探讨在限制能量减重状态下,黄烷醇是否能发挥少减或不减骨量的骨保护效应。如有,该效应是否通过与F.plautii 菌相互作用发挥。  

Objectives of Study:

This randomized, double-blind, placebo-controlled trial was designed to investigate whether flavanols could provide bone protection with little or no bone loss during energy-restricted weight loss. If so, whether the effect is exerted through interaction with F. prautii.

随机方法(请说明由何人用什么方法产生随机序列):

按照研究对象进入干预的顺序,采用最小随机化,以性别、年龄、BMI及是否绝经作为重要混杂因素将 160 名研究对象分为 2 组。1-160 号所对应的组别由不透明的信封封存。随机方法的实施由不参与本项研究的人员进行,并由其单独保管相关分组过程资料。

Randomization Procedure (please state who generates the random number sequence and by what method):

According to the order of the subjects entering the intervention, a total of 160 subjects were divided into two groups with gender, age, BMI and menopause as important confounding factors by minimal randomization. Groups corresponding to numbers 1-160 are sealed in opaque envelopes. Randomization was performed by personnel who were not involved in the study and who kept the study-group assignments separately.

盲法:

委托湖南佳沐生物科技有限公司加工形状、颜色、气味和包装均一致的补剂和安慰剂。补充剂和安慰剂按每人 6 个月所需的总量,由加工工厂在补充剂外包装上标注序号(1-160),每一序号对应的补充剂内容由不参与研究招募、分组、资料收集与分析的研究人员掌握,研究对象及直接与研究对象接触的研究人员均不知道代号。当研究结束、资料收集完毕和实验室检测及主要研究资料分析完成后解密。

Blinding:

Hunan Jiamu Biotechnology Co., Ltd. was commissioned to process the supplement and placebo with the same shape, color, smell and packaging. The supplement and placebo were labeled with serial numbers (1-160) according to the total amount required for 6 months by the processing factory. The supplement contents corresponding to each serial number were held by the investigators who were not involved in the recruitment, grouping, data collection and analysis of the study, and the code numbers were unknown to the study subjects and to the investigators who were in direct contact with the study subjects. After the end of the study, data collection, laboratory testing and analysis of the main study data were completed, the data were decrypted.
