The participants of the TCS cohort had all completed at least one semester of an open university course. Over 87,000 students returned the baseline questionnaire in 2005, and a random 10% of the cohort were followed up after two years, with full cohort follow ups in 2009 and 2014. The cohort was approximately 52% female, and aged between 15 and 87 years at baseline.
