Table 4 Logistic regression of young adult SES on MRB score, stratified by early life SES variables

From: Is adolescent multiple risk behaviour associated with reduced socioeconomic status in young adulthood and do those with low socioeconomic backgrounds experience greater negative impact? Findings from two UK birth cohort studies

  1. aModels in BCS70 were adjusted for sex and conduct score at age 10 and sex, IQ score age 8, conduct score at age 10, Key Stage 2 score and season born for ALSPAC
  2. bEarly life SES variables are binary variables, with high SES as the reference category
  3. cLikelihood ratio test p-values are presented, with p ≤0.05 taken as evidence of difference between the groups and thus a moderation effect. OR are presented indicating the odds of the outcome for each incremental single behaviour out of a possible eight behaviours for BCS70 and thirteen behaviours for ALSPAC, stratified by origin SES
