Figure 1.

Proportion of cohort members in each study with a lifetime diagnosis of one or more mental disorders (see Table 1 for Study characteristics). Error bars represent 95% confidence intervals. Green bars represent estimates drawn from Danish registry data. Blue bars represent estimates from cross-sectional epidemiological surveys. Red bars represent estimates from prospective longitudinal studies with repeated mental health assessments. The estimates shown for the Christchurch Study and Dunedin Study are based on subsets (N = 1,041 and 988, respectively) of the full cohorts (N = 1,265 and 1,037, respectively) who contributed data to 3 + assessment waves. Age Range = age of cohort members at first mental health assessment, presented as a single number, range, or as “mean (SD)” where appropriate. No. of assessments = number of assessment waves in each longitudinal study; Length of follow-up = duration of longitudinal follow-up across assessments.
