Abstract

The Norwegian Institute of Public Health in Oslo has an ongoing program of twin research using population-based cohorts of twins. The current database includes information on twins identified through the Medical Birth Registry of Norway and born from 1967–1979, altogether 15,370 twins. This is a longitudinal study with a cohort sequential design whereby new cohorts are recruited into the study at 5–6 year intervals. Sub-samples of these twins have participated in questionnaire studies and clinical assessment sub-projects. These projects include national and international collaborations. Our primary areas of interest include mental health and psychological well-being, obesity, asthma and allergies, health behaviors and health perceptions, comorbidity, and perinatal influences on health outcomes. This paper provides a brief overview of the data, sample, and the various research projects associated with this twin program of research.
