Results are interpreted as the difference in HRQoL when time spent in one behaviour is increased at the expense of another, while the remaining two behaviours remain constant.
Analysis performed using multivariable linear regression models, results presented as the predicted changes in HRQoL scores at age 10 years and their 95% confidence intervals reported within the brackets. Models were adjusted for sex, ethnicity, maternal education level, child's categorical weight status at age 8 years, and whether the participant was followed up before or after the onset of the COVID-19 pandemic.
