It has recently come to our attention that the above paper contains an error. One of the variables in table 3 labelled “moderate activity ≥ three times a week”, and also referred to in the text as “Achieving recommended levels of physical activity”, was extracted incorrectly. Please see below an updated version of table 3 with the changes highlighted. The numbers of participants who are positive for this measure is much reduced, but our conclusion that there was no difference between the groups is unchanged.
Table 3 Socioeconomic factors by status for lifetime occurrence (people may be included in more than one category). See lettered table notes, and Appendix 2 for full case definitions

k) Criteria met for adverse situations as an adult: lack of confiding relationship, abusive relationships and money problems.
