NCT05603455

Brief Summary

This study will include middle-aged and elderly people aged 45-65 years to carry out the translational study of Bifidobacterium adolescentis, and design a double-blind, randomized controlled clinical trial according to strict inclusion/exclusion criteria, using aging-related functional indicators, intestinal flora, DNA methylation and other advanced aging characteristic examination methods to fully and accurately assess the effects and safety of Bifidobacterium adolescentis on aging, which has the advantages of strong safety, high practice and high credibility compared with previous clinical trial protocols, laying an important foundation for improving probiotic anti-aging and exploring the development of aging intervention programs suitable for the Chinese population.

Outcome Measures

Primary Outcomes (11)

  • Aging Ai 3.0

    Calculating physiological age through physical examination indicators.The lower the physiological age calculated by Aging Ai 3.0, the better the health status.

    Change from Baseline physiological age calculated by Aging Ai 3.0 at 6 months

  • Fasting glucose in mmol/L

    Within the normal range(3.9\~6.1 mmol/L), the health status is good

    Change from Baseline Fasting glucose at 6 months

  • BMI(Body Mass Index)in kg/m^2 BMI

    Within the normal range, the health status is good

    Change from Baseline BMI in kg/m^2 at 6 months

  • Epigenetic clock

    physiological age was calculated by Epigenetic clock through DNA methylation.The lower the physiological age calculated by Epigenetic clock, the better the health status.

    Change from Baseline physiological age calculated by Epigenetic clock at 6 months

  • Bone density in g/cm^3

    The higher the Bone density, the better the health status

    Change from Baseline Bone density in g/cm3 at 6 months

  • Triglycerides in mmol/L

    Within the normal range(2.26\~5.6 mmol/L), the health status is good

    Change from Baseline Triglycerides at 6 months

  • Cholesterol in mmol/L

    Within the normal range(3.6\~5.2 mmol/L), the health status is good

    Change from Baseline Cholesterol at 6 months

  • Telomere level

    Telomere level was detected by qRT(quantitative real-time)-PCR(Polymerase Chain reaction). The lower the Cycle Threshold,the higher the Telomere level,which means the healthier and younger.

    Change from Baseline Telomere level at 6 months

  • Blood pressure

    Within the normal range, the health status is good

    Change from Baseline Systolic Blood Pressure and diastolic blood pressure at 6 months

  • body fat percentage

    The higher the body fat percentage, the better the health status

    Change from Baseline body fat percentage at 6 months

  • Markers for cell senescence

    The expression level of Markers for cell senescence was detected by qRT(quantitative real-time)-PCR(Polymerase Chain Reaction).The higher the Cycle Threshold,the lower the expression level of Markers for cell senescence, which means the healthier.

    Change from Baseline the expression level of indicators at 6 months

Secondary Outcomes (4)

  • Flora Clock

    Change from Baseline physiological age calculated by Flora Clock at 6 months

  • Mini-Nutritional Assessment

    Change from Baseline score at 6 months

  • The Medical Outcomes Study Short Form 36(SF-36)

    Change from Baseline score at 6 months

  • Pittsburgh sleep quality index

    Change from Baseline score at 6 months
