In this retrospective longitudinal study including UK and US participants, we collected diet and lifestyle data pre-pandemic (896,286) and peri-pandemic (291,871) using a mobile health app, and we computed a bidirectional health behaviour disruption index. Disruption of health behaviour was higher in younger, female and socio-economically deprived participants. Loss in body weight was greater in highly disrupted individuals than in those with low disruption. There were large inter-individual changes observed in 46 health and diet behaviours measured peri-pandemic compared with pre-pandemic, but no mean change in the total population. Individuals most adherent to less healthy pre-pandemic health behaviours improved their diet quality and weight compared with those reporting healthier pre-pandemic behaviours, irrespective of relative deprivation; therefore, for a proportion of the population, the pandemic may have provided an impetus to improve health behaviours. Public policies to tackle health inequalities widened by the pandemic should continue to prioritize diet and physical activity for all, as well as more targeted approaches to support younger females and those living in economically deprived areas. date: 2021-12-16 date_type: published publisher: NATURE PORTFOLIO official_url: http://dx.doi.org/10.1038/s43016-021-00398-3 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1911913 doi: 10.1038/s43016-021-00398-3 lyricists_name: Sudre, Carole lyricists_id: SUDRE45 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Nature Food volume: 2 number: 12 pagerange: 957-969 pages: 14 citation: Mazidi, M; Leeming, ER; Merino, J; Nguyen, LH; Selvachandran, S; Pujal, JC; Maher, T; ...
