HELMi is a birth cohort that aims to identify environmental, lifestyle and genetic factors that modify the intestinal microbiota development in the first years of life and their relation to child health and well-being. The cohort consists of 1,055 healthy-term infants born between 2016 and 2018, mainly in the capital region of Finland, and their parents. Participants were followed from birth to 24 months through weekly to monthly questionnaires and repeating microbiota sampling. Home dust samples were collected when the children were between 1.5 and 3 years old. In 2021, a follow-up began to assess participants at ages 4 to 5 years, with plans for additional follow-ups every 4 to 5 years for over 15 years.
