Background
The COVID-19 lockdowns had negative effects on children’s and adults’ mental and physical health. There is, however, a paucity of research that explores differences in health-related quality of life (HRQL) and well-being over time after the COVID-19 lockdowns had been lifted. Furlough during lockdowns, increases in unemployment, and the emerging cost-of-living crisis all put pressure on family finances, which could have a detrimental effect on HRQL and well-being. This study, part of the wider Active-6 study, explored how HRQL, capability well-being and family financial strain changed after the lockdowns, the relationship between these outcomes, and whether physical activity had any mediating effect on differences in HRQL and capability well-being.

Methods
Cross-sectional data were collected in May–December 2021 (Wave 1) and January–July 2022 (Wave 2). Children (aged 10–11) and their parent/carer were recruited from 23 to 27 schools in each wave, respectively, and completed validated questionnaires measuring HRQL (adults – EQ-5D-5L, children – CHU9D), capability well-being (adults – ICECAP-A) and family financial strain (adults – Family Economic Strain Scale, FESS). Children also completed questions on capability well-being. Weekday minutes of moderate-to-vigorous physical activity (MVPA) were measured using accelerometers. Mixed-effects regression models, adjusted for gender, age group (adults only), IMD and highest household education, were used to explore differences in HRQL and capability well-being between waves. In addition, the moderating effect of financial strain and the mediating effect of MVPA on HRQL and capability well-being were explored.

Results
Active-6 recruited 393 parent-child pairs in Wave 1 and 436 in Wave 2. There were no differences in HRQL (EQ-5D, CHU9D) and capability well-being (ICECAP-A) scores between waves, but financial strain was worse in Wave 2 compared to Wave 1 (FESS score difference 1.14 adjusted 95% CI 0.15 to 2.12). Increased financial strain was associated with lower (worse) EQ-5D-5L, CHU9D and ICECAP-A scores. There was no evidence of a mediating effect of MVPA.

Limitations and future work
Pre-COVID-19 data on HRQL were not collected, so analysis was limited to post-lockdown only. Participating parents were predominantly female and participation was lower among lower socio-economic groups, limiting our ability to explore inequalities. Intervention planning to increase physical activity and health and well-being during the COVID-19 recovery should consider the financial strain families are experiencing and the negative implications of financial strain on HRQL.

Conclusions
There were no differences in HRQL and capability well-being in children and adults after lockdowns lifted in 2021 and a year later in 2022. The results indicate increasing financial strain, which could reflect the UK’s ‘cost of living crisis’.
