Fig. 2: Group-based trajectories of depressive symptoms and CRP.

Sample: ALSPAC (Nā=ā3931). The latent class growth analysis resulted in the following trajectories: (1) Depression: Class 1ālow depressive symptoms (68.9%), representing participants with low depressive symptoms at all assessments; Class 2āmoderate depressive symptoms (23.8%), representing participants with moderate depressive symptoms at all assessments; Class 3āsevere depressive symptoms (7.4%), representing participants with high levels of depressive symptoms at all assessments; (2) CRP: Class 1ālow-moderate CRP (69.8%), representing participants with low levels in late childhood and moderate levels in adolescence; Class 2āmoderate-high CRP (19.5%), representing participants with moderate levels in late childhood and high levels in adolescence; Class 3āhigh-moderate CRP (10.6%), representing participants with high levels in late childhood but lower levels in adolescence. The ālow depressionā and ālow-moderate CRPā trajectories were used as reference categories in multinomial logistic regression analysis.
