Summary

This study was designed to follow a group of adolescents who were previously examined by questionnaire and pulmonary function tests when they were aged 8-10 years old. Approximately 50% of the population in 10 towns were seen again at age 17-18. Questionnaires and pulmonary function were repeated.
