NINFEA project

Study design

NINFEA is an internet-based multi-purpose mother-child cohort i set up to investigate the effects of exposures acting during pre-natal and early post-natal life on infant, child and adult health.

Members of the cohort are all babies born to women who:

  • have access to the internet,
  • have enough knowledge of the Italian language to complete the online questionnaires,
  • become aware of the study,
  • volunteer to participate.

Women are recruited during pregnancy. To participate they register at the study website and complete a baseline online questionnaire (Q1).

Participants complete three main online questionnaires :

  • during pregnancy (Q1),
  • 6 months after delivery (Q2),
  • 18 months after delivery (Q3).

The questionnaires include questions on the mother and/or the child on several exposures and some outcomes, including environmental exposures (passive smoking, traffic, residential history, maternal occupation and occupational exposures, noise, dampness), reproductive factors, medical history, anthropometrical measures, diet, supplements, health status, asthma, growth, etc.

Women are invited via email and/or telephone or mail to complete the Q2 and Q3 questionnaires.

Follow-up is conducted using both active and passive methods.

Currently the follow-up questionnaires are at 4, 7, 10, 13 and 16 years of the child. Passive follow-up involves linkage with available population registries, including the Hospital Inpatient Registry, the Birth Registry, the Cancer Registry, etc.

All participants were invited to fill in a short online anonymous questionnaire in April 2020 which aims to investigate COVID-19 the households, with particular focus on children and, again, at the end of 2020, women were invited to complete a full follow-up questionnaire COVID related.

The NINFEA project intends to deepen the study of the health effects of exposure to electromagnetic fields. For this purpose, specific questions were formulated to be proposed twice, one and a half years apart, to the mothers of the participants in the 10-13 age group.

The NINFEA follow-up continues with the 19-years questionnaire which involves the direct involvement of boys and girls who are now adults; mothers in the cohort who wish to continue participating in the project are also subjected to new questionnaires.

To explore environmental exposures and the related influences on the human epigenome, at the end of the second questionnaire (6 months), women were asked to donate a sample of their own saliva and a sample of their child's saliva. At the 19-year questionnaire, participants who are now adults are asked if they are available to participate in the new collection of a saliva sample.
