Study profile
*Parents were not assessed in wave six. †Participants did not have to respond at all waves to be included in the analysis and those not responding at a particular wave were still contacted at subsequent waves unless they actively withdrew from the study or were lost to follow-up because they had no valid contact details; see table 2.
