Abstract

BACKGROUND: Introducing complementary foods other than breastmilk or formula acutely changes the infant gut microbiota composition. However, it is unknown whether the timing of introduction to complementary foods (early vs. late) in infancy is associated with early childhood gut microbiota and BMI, and if these associations depend on breastfeeding duration. OBJECTIVE: Our primary objective was to investigate whether timing of infant complentary feeding with solid foods is associated with early childhood gut microbiota composition and BMI-z, and whether these associations differ by duration of breastfeeding. METHODS: We used data from a Canadian pre-birth cohort followed till age 5 years. We examined timing of introduction to solid foods with the gut microbiota, determined by 16S rRNA gene sequencing of stool collected at 5 years of age, and age-and-sex specific BMI-z. We conducted analyses before and after stratifying by breastfeeding duration, and adjusted for delivery mode, gestational age and birth weight. RESULTS: Of the 392 children in the analysis, 109 (27.8%) had early (≤4 months) solids. The association between early (vs later) solids and BMI-z at 5 years was modified by breastfeeding status at 4 months (P = .06). Among children breastfed >4 months, early (vs later) solids were associated with differential relative abundance of 6 bacterial taxa, including lower Roseburia, and 0.30 higher BMI-z (95% CI: 0.05, 0.55) at 5 years. In children breastfed <4 months, early solids were associated with differential relative abundance of 9 taxa, but not with child BMI-z. CONCLUSIONS: Early (vs. later) introduction to solid foods in infancy is associated with altered gut microbiota composition and BMI in early childhood, however these associations differ by duration of breastfeeding.

  • Accelerated maturation of the gut microbiota has been proposed as a contributing pathway to the detrimental effects of early weaning on host processes.

    “Due to the known profound effects of the microbiota on host development, accelerated maturation of the gut microbiota has been proposed as a contributing pathway to the detrimental effects of early weaning on host processes (275).”
  • In human studies, early introduction of solid food was associated with a higher risk of obesity or immunological diseases.

    “In human studies, early introduction of solid food was associated with a higher risk of obesity (274, 275) or immunological diseases (276).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
