Abstract

The gut microbiome is associated with bone mass acquisition, yet evidence in childhood remains limited. Given that lower peak bone mass predicts osteoporosis in later life, understanding early influences is important. This analysis explores the association between the early life gut microbiome and bone health in later childhood. Data was obtained from 700 children recruited in pregnancy and followed prospectively within the Copenhagen Prospective Studies on Asthma in Childhood2010 cohort, a population-based mother-child cohort. The infant gut microbiome was measured at 1 wk (n = 445), 1 mo (n = 492), 1 yr (n = 508), 4 yr (n = 350), and 6 yr (n = 327) of age by 16S ribosomal ribonucleic acid amplicon sequencing targeting the fourth variable region. Total body less head bone mineral density and area-adjusted bone mineral content were measured by dual-energy X-ray absorptiometry at 6 yr of age. Associations were investigated by multiple linear regression, permutational analysis of variance, differential abundance analysis, and Random Forest machine learning. There were few associations between the early-life gut microbiome and bone health outcomes at age six. We found negative associations between alpha (within-sample) diversity and area-adjusted bone mineral content at 4 yr. Beta (between-sample) diversity of the gut microbiome at 6 yr was associated with concurrent bone mineral density. Escherichia-Shigella abundance at 1 mo of age associated with lower bone mineral density. Sutterella abundance at 1 yr was associated with lower bone mineral density and area-adjusted bone mineral content at 6 yr. There were no other associations between the gut microbiome and bone outcome measures at any time point. In a well-powered unselected cohort study with longitudinal sampling of the gut microbiome, there were some suggestive but no consistent associations between the early gut microbiome and bone health outcomes at 6 yr of age.

早期生命中的肠道微生物组和6岁时的骨骼健康结果:一项丹麦母婴队列研究
肠道微生物群与骨量获得有关,但在儿童时期的证据仍然有限。考虑到较低的峰值骨量预示着晚年的骨质疏松症,了解早期的影响是很重要的。该分析探讨了儿童早期肠道微生物群与儿童后期骨骼健康之间的关系。数据来自700名妊娠期儿童,并在哥本哈根儿童哮喘前瞻性研究2010队列中进行前瞻性随访,这是一个以人群为基础的母婴队列。在婴儿1周(n = 445)、1个月(n = 492)、1岁(n = 508)、4岁(n = 350)和6岁(n = 327)时,采用针对第四个可变区域的16S核糖体核糖核酸扩增子测序法测定婴儿肠道微生物组。6岁时用双能x线骨密度仪测定全身减头骨密度和面积调整骨矿物质含量。通过多元线性回归、置换方差分析、差分丰度分析和随机森林机器学习来研究相关性。幼年时期的肠道微生物群与6岁时的骨骼健康状况之间几乎没有关联。我们发现α(样本内)多样性与4年时的区域调整骨矿物质含量呈负相关。6年时肠道微生物组的β(样本间)多样性与同期骨矿物质密度相关。1月龄时的大肠杆菌-志贺氏菌丰度与较低的骨密度有关。1年时沙特尔菌丰度与6年时较低的骨密度和面积调整骨矿物质含量相关。在任何时间点,肠道微生物组与骨骼结果测量之间都没有其他关联。在一项对肠道微生物群进行纵向采样的有力非选择队列研究中,早期肠道微生物群与6岁时骨骼健康结果之间存在一些暗示但不一致的关联。

期刊介绍: The Journal of Bone and Mineral Research (JBMR) publishes highly impactful original manuscripts, reviews, and special articles on basic, translational and clinical investigations relevant to the musculoskeletal system and mineral metabolism. Specifically, the journal is interested in original research on the biology and physiology of skeletal tissues, interdisciplinary research spanning the musculoskeletal and other systems, including but not limited to immunology, hematology, energy metabolism, cancer biology, and neurology, and systems biology topics using large scale “-omics” approaches. The journal welcomes clinical research on the pathophysiology, treatment and prevention of osteoporosis and fractures, as well as sarcopenia, disorders of bone and mineral metabolism, and rare or genetically determined bone diseases.
