Follow Up
Register-linkages to various medical registers have taken place. Since the 1990 questionnaire, many twins have been asked to participate in selected sub-studies which have focused on specific study questions and traits, but no unselected questionnaire survey had been conducted after that. In 2011 a questionnaire was mailed for the 35-year follow-up.
