All analyses used generalised linear models with logit link. Significant p values are highlighted in bold.
Adjustment was made for the individualised combined weight (accounting for non-response and stratified cohort design where appropriate), sex, ethnicity, highest educational attainment (adult SEP), childhood SEP, presence of chronic illness and shielding letter.
*COVID-19 infection was coded as 0=no, 1=yes.
†Change in financial situation was coded as 0=same or better, 1=worse.
‡Change in trust in government was coded as 0=same or more, 1=less.
§Change in conflict during lockdown was coded as 0=less, 1=same or more.
¶Change in household composition during lockdown was coded as 0=no, 1=yes.
**Change in psychological distress during lockdown was coded as 1=an increase in the mental health score, 0=same or lower score.
††Change in alcohol consumption was coded as 1=more drinks per week during lockdown compared with pre-lockdown or 0=same or lower.
‡‡Change in smoking was coded as 0=same or less cigarettes smoked during lockdown compared with before lockdown, 1=more cigarettes.
§§Change in sleep duration was coded as 0=same or more hours slept during lockdown and 1=less hours slept during lockdown.
