Design
- Study design
- Cohort
- Follow Up
- Since recruitment, mothers have completed two questionnaires during pregnancy (less than 25 weeks and 34 to 36 weeks gestation). Children and mothers were followed up when the children were 4 months, 1, 2, 3, 5, 8 and 12 to 14 years of age. Participants who agreed to be contacted for additional research were mailed a flood impact questionnaire in the autumn of 2013 and three COVID-19 impact questionnaires between May 2020 and January 2022.
- Supplementary Information
- Starting from the COVID-19 questionnaire in 2020, youth participants may complete their own questionnaires if their mothers consent to it.
