  1. inactive: physical activity < 30 min./day on 5 d./w, based on the SQUASH questionnaire, which was completed by 89 controls and 85 intervention participants. For missing data, treatment indication was based on the 2 questions about physical activity from the invitation letter.
  2. * Level of education: 1 = no education or only primary education 2 = lower secondary education, 3 = higher secondary education, 4 = college or university.
