Brief Summary

In this project, the investigators aim to investigate the effects of soy consumption at early life on the development of gut microbiota and bone growth. The hypothesis to be tested is that early-life exposure to soy optimize bone growth via the alteration of gut microbiota composition. Clinical samples from mother-child pairs recruited into the SMART Gen Hong Kong cohort will be used to examine the association between maternal soy intake with infant gut microbiota and child's bone development. Primary outcome: Bone mineral density; dynamic bone formation parameters; messenger ribonucleic acid (mRNA) expression of bone markers. Secondary outcome: Gut microbiome profile; metabolomic profile in serum, urine or feces; correlation between soy-induced gut microbiota or metabolites and bone growth. The investigators expect that early life exposure to soy will improve bone growth via gut microbiota and provide scientific evidences for the use of soy preparation in early life as a preventive measure for optimizing bone health.

RECRUITING

Biospecimen

Retention: SAMPLES WITHOUT DNA

At around 36-month postpartum, mother and child will provide one urine sample (10-15 ml) for assessing equol production. Bone assessment will be performed when the child is at the age of 6 years old in a designated site at the Prince of Wales Hospital in Shatin: The child will undergo high-resolution peripheral quantitative computed tomography (HR-pQCT) to measure the cross-sectional geometry, volumetric bone mineral density, and bone microstructure at the distal radius of the non-dominant forearm. The scan region is 4% of the forearm length proximal to the lateral edge of the radial joint surface of the wrist. (Optional) The child will provide blood (2-3 ml) and urine sample (10-15 ml) for measuring bone markers.
