Trajectories of probability of depression symptom episodes over time in the NPHS (2000/01-2010/11).

<p>Trajectories from a 3-class latent class growth model incorporating age, sex, marital status, education, income adequacy, childhood life events, chronic condition and family history of depression. The red line represents the trajectory with high prevalence of depression symptom episodes; the green line, moderate prevalence; the blue line, low prevalence.</p

Association of time-varying neighbourhood variables with the log-odd of having an episode of depressive symptoms over the study period within each trajectory class.

<p>All models were weighted using Statistics Canada survey weights and included age, sex, marital status, education, income adequacy, childhood life events, chronic condition and family history of depression.</p

Association between baseline characteristics and trajectory class of depression symptom episodes.

<p>All estimates were weighted using Statistics Canada survey weights.</p
