AKK Study in Improving Obesity and Metabolic Status in Children and Adolescents

Официальное название

A Randomized, Double-blind, Placebo-controlled Study of Akkermansia Muciniphila AKK PROBIO in Improving Obesity and Metabolic Abnormalities in Children and Adolescents Aged 7-18 Years

Обзор

The problem of obesity among children and adolescents is becoming increasingly serious and may affect their health in adulthood. Researches have found that a type of probiotic in the intestinal tract - "Akkermansia muciniphila" (referred to as AKK), may help regulate metabolism and weight. Although it has shown effects in adults, its safety and efficacy in children and adolescents still need further verification. This study aims to evaluate the effects of supplementing Akkermansia Muciniphila AKK PROBIO on weight, metabolic health and intestinal flora of obese children and adolescents aged 7 to 18.

Подробное описание

This study aims to evaluate the improvement effect of continuous supplementation with pasteurized inactivated Akkermansia muciniphila (AKK PROBIO) for 12 weeks on the body mass index z-score of obese children and adolescents aged 7 to 18 years, and systematically explore its impact on metabolic health indicators, anthropometric indicators, and sleep, as well as to clarify the safety and tolerance of this intervention. Through the integrated analysis of metagenomics and non-targeted metabolomics, the potential mechanism by which AKK PROBIO regulate the intestinal microbiota and host metabolic profiles in children and adolescents is revealed, providing a scientific basis and biomarker support for the development of precision nutrition intervention strategies for childhood and adolescent obesity.

Вмешательства

• Биопрепарат AKK
  This intervention trial intends to use pasteurized AKK PROBIO, with each dose containing the equivalent of 30 billion inactivated bacterial cells. AKK PROBIO is a research hotspot in the field of intestinal microecology. The pasteurized AKK PROBIO (belonging to prebiotics) have been proven to have good safety and metabolic improvement effects in adults. Compared to live bacterial preparations, the inactivated form has higher stability, a longer shelf life, and better safety. AKK group (n=50): Th
• Препарат Placebo (maltodextrin)
  Placebo group (n=50): The subjects took one placebo capsule (containing inert ingredients such as maltodextrin) identical in appearance and taste to the AKK probiotic capsules before each breakfast and dinner every day for 12 consecutive weeks. After the study ended, the subjects in the placebo group could receive the same dose and specification of AKK probiotic capsules.
