NewTwin – Genetic, Social and Environmental Factors Impact on Health and Behavior - A Study from the Swedish Twin Registry

This ongoing twin study, initiated in 2021, focuses on all twins born in Sweden. Parents are invited to complete an online questionnaire when their twins are approximately nine months old. The questionnaire includes areas such as pregnancy, neonatal care, screen time and parental health habits. Additionally, saliva samples are collected to determine the twins' zygosity and genotyping. The genotype data is used in genetic association studies to explore diseases, health-related traits and behaviors. Question Areas: Parents' education, income and occupation Fertility treatment Parents’ health Parents’ smoking and alcohol habits (current and during pregnancy) Pregnancy from the mother's perspective Pregnancy from the twins' perspective Birth weight and length Neonatal care Breastfeeding Vaccinations Twin development Sleep habits of the twins Zygosity, twin similarities and differences Family screen time and screen use
