1989-95 cohort

Among the 1989-95 cohort, nearly 70% responded to Survey 2 in 2014, 55% to Survey 3 in 2015, 59% responded to Survey 4 in 2016 and 56% to Survey 5 in 2017 (See Table below). Retention of young women was associated with older age, higher education, higher self-rated health status, and low engagement with adverse health behaviors, the method of recruitment was a key determinant of study participation in the multivariate model. Although women were more likely to be recruited into the cohort via social media (eg, Facebook), retention over time was higher for women recruited through traditional media and referral approaches.
