Infant Weight and Gut Microbiota Data from a Maternal Yoghurt Intervention Study

Clinical trial data from a study of 226 infants examining the effects of maternal overweight/obesity and probiotic yoghurt supplementation on infant weight and gut microbiota composition. The dataset includes infant weight measurements at 42 days and 3 months, and gut microbiota alpha diversity (Shannon index) and relative abundance data for genera like Akkermansia and Lactobacillus over 0–6 months. The data was authored by Longlong Jia and last updated in March 2026.

Use Cases

• Analyze correlations between infant weight and specific gut bacteria like Veillonella and Akkermansia based on the study's findings.
• Compare gut microbiota diversity (Shannon index) between intervention and control groups over the first six months of life.
• Model the temporal dynamics of bacterial genera such as Blautia and Lactobacillus across different maternal BMI groups.
• Investigate the impact of a maternal dietary intervention on infant enterotype composition during early development.

Strengths

• Data originates from a controlled clinical trial with 226 infants across three defined groups (YC, NC, CC).
• Includes longitudinal measurements of infant weight and gut microbiota over a 6-month period.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small (14.5 KB), suggesting it contains summary or processed results rather than raw sequencing data.
• Geographic and demographic details of the study population are not specified in the provided metadata.
