中文摘要:
      目的:使用两样本孟德尔随机化(TSMR)作为研究方法,探索肠道菌群与运动动机之间的因果关联。方法:使用肠道菌群和运动动机的全基因组关联研究(GWAS)的汇总数据进行分析。主要使用逆方差加权(IVW),根据效应指标优势比(OR)和95%置信区间(CI)评估结果。采用加权中位数、MR-Egger回归等方法计算补充结果,结合敏感性分析用于检验结果的稳定性和可靠性。结果:普氏栖粪杆菌属(Faecalibacterium)(OR=1.01,95%CI[1.00,1.03],P=0.003)、梭状芽孢杆菌属(Clostridium)(OR=1.01,95%CI[1.00,1.01],P=0.007)、粪球菌属(Coprococcus1)(OR=1.00,95%CI[0.99,1.01],P=0.876)、乳杆菌目(Lactobacillales)(OR=1.02,95%CI[1.01,1.03],P=0.003)、肠杆菌属(Intestinibacter)(OR=1.01,95%CI[1.00,1.02],P=0.002)和霍华德属(Howardella)(OR=1.01,95%CI[1.00,1.01],P=0.001),以上6种肠道菌群的丰度升高会促进中高强度运动动机(MVPAM)和激烈运动动机(VPAM)的提升,增加运动动机的表现,具有正面促进作用;红螺菌科(Rhodospirillaceae)(OR=0.99,95%CI[0.98,1.00],P=0.05)、克里斯滕森氏菌(Christensenellaceae)(OR=0.97,95%CI[0.96,0.99],P=0.006)和巴氏杆菌目(Pasteurellales)(OR=1.01,95%CI[1.00,1.02],P=0.105),以上3种菌群的丰度升高与运动动机存在抑制作用,会降低运动动机的表现。结论:通过两样本孟德尔随机化全面评估了418种肠道菌群对两种强度运动动机的因果效应。
英文摘要:
      Using Two-Sample Mendelian Randomization (TSMR) as a research methodology to explore the causal relationship between gut microbiota (GM) and physical activity motivation (PAM). Methods: Analyze summary data from Genome-Wide Association Studies (GWAS) of GM and PAM. Mainly utilize Inverse Variance Weighting (IVW) as the primary analysis method, assessing results based on effect size odds ratio (OR) and 95% confidence intervals (CI). Supplementary results are computed using methods like Weighted Median Estimation, MR-Egger regression, combined with sensitivity analysis to examine the stability and reliability of the results. Results: Faecalibacterium (OR=1.01, 95%CI[1.00,1.03], P=0.003), Clostridium (OR=1.01, 95%CI[1.00,1.01], P=0.007), Coprococcus 1 (OR=1.00, 95%CI[0.99,1.01], P=0.876), Lactobacillus (OR=1.02, 95%CI[1.01,1.03], P=0.003), Escherichia (OR=1.01, 95%CI[1.00,1.02], P=0.002), and Howardella (OR=1.01, 95%CI[1.00, 1.01], P=0.001), an increase in the abundance of the six gut microbiota mentioned above will promote the enhancement of MVPAM and VPAM, increase the performance of exercise motivation, and have a positive promoting effect; The abundance of Rhodospirillaceae (OR=0.99, 95%CI[0.98,1.00], P=0.05), Christensenellaceae (OR=0.97, 95%CI[0.96,0.99], P=0.006), and Pasteurelales (OR=1.01, 95%CI[1.00,1.02], P=0.105) increases and has an inhibitory effect on exercise motivation, which can reduce the performance of exercise motivation. Conclusion: Through Mendelian Randomization, a comprehensive evaluation of 418 gut microbiota species on two levels of physical activity motivation was conducted.
