Brief Summary

This protocol explains the MAINHEALTH cohort. The study examine the influence of maternal health parameters on human breast milk composition and integrates milk phenotype with infant metabolism and infant gut microbial content and metabolism.

Outcome Measures

Primary Outcomes (1)

  • Metabolite profile of human milk

    Human milk metabolites by Nuclear Magnetic Resonance (NMR) spectroscopy. Data will be analysed as absolute concentrations of milk metabolites; how milk metabolite profiles are related to mother's blood chemistry, milk microbial profiles, milk oligosaccharides, infant urine metabolome, and infant fecal microbiomes will be explored using multivariate analyses.

    Birth to 3 months

Secondary Outcomes (12)

  • Metabolite profile of human milk by Liquid Chromatography-Mass Spectrometry (LC-MS) analysis

    Birth to 3 months

  • Milk proteome profile

    Birth to 3 months

  • Milk protein post-translational modification (PTM) profile

    Birth to 3 months

  • Milk glycome profile

    Birth to 3 months

  • Microbial structure of human milk

    Birth to 3 months

  • +7 more secondary outcomes

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Residence in Aarhus area is necessary and Aarhus University Hospital has to be the place of giving birth. This is due to samples being collected by midwifes during labor and when study personnel collect samples in study participants' homes.

You may qualify if:

  • Residing in Aarhus area
  • Above 18 years of age
  • BMI above 18.5 kg/m2
  • Intention to breastfeed the first four to six months following birth
  • Be able to communicate in Danish

You may not qualify if:

  • Smoking
  • Multiple gestation
  • Suffering from the following chronic diseases that demands medical treatment: diabetes mellitus, celiac disease, inflammatory bowel disease (Chrohn's disease or ulcerosa colitis)
  • Taking medicaments for irritable bowel syndrome
  • Taking medicine for metabolic disorders
  • Taking medicine for psychological disorders
  • Have had gastric bypass surgery
  • Planned caesarean section
  • Received antibiotics after week 12 in their pregnancy
  • Utilizing significant amount of infant formula following birth
  • Infants born after gestational age 37 weeks
  • Infants with a birth weight between 2500 g and 5000 g
  • Inborn errors of metabolism
