Statistically significant estimates (95% CI) in bold type. Models 1: Adjusted for G1 birth order and three bands of G1 birth years. Models 2: Model 1 + parents’ social class and marital status at G1 birth and mutually adjusted.

Models 3: Model 1 + parents’ social class and marital status at G1 birth.
