Change (per 10-year) in childhood socio-economic position inequalities (Slope Index of Inequality, SII (95% CI)) in adult adiposity and blood pressure (negative numbers indicate reduced childhood socio-economic position inequalities with increasing age, and positive numbers indicate increased socio-economic position inequalities with increasing age)

  • Models a–d are performed on the same sample with non-missing education and adult socio-economic position.

  • * SII modelled using mixed regression with random intercept and slope; fixed effects are reported.
