Id Subject Object Predicate Lexical cue
T57 0-4 Sentence denotes 2.3.
T58 5-25 Sentence denotes Statistical Analysis
T59 26-110 Sentence denotes Only participants with complete data for all sections were included in the analysis.
T60 111-291 Sentence denotes Mean (standard deviation, SD), median (interquartile range, IQR), and proportions were used to describe participants on key characteristics and outcomes based on data distribution.
T61 292-450 Sentence denotes Comparisons between sociodemographic characteristics were performed using parametric and non-parametric tests to compare behaviors before and during COVID-19.
T62 451-520 Sentence denotes Multicollinearity was assessed with variable inflation factors (VIF).
T63 521-842 Sentence denotes We used multiple linear regressions with a residualized change score approach [13,14] to investigate the sociodemographic predictors (independent variables) of changes in physical activity, recreational screen time, sleep duration, and sleep quality (dependent variables) during the early stages of the pandemic in Chile.
T64 843-1027 Sentence denotes This approach provides robust estimates by eliminating auto-correlated errors and regression towards the mean, which often makes it preferable to the simple change score approach [13].
T65 1028-1205 Sentence denotes First, we regressed the standardized score during the COVID-19 pandemic on the standardized scores before the COVID-19 pandemic for each of the behaviors assessed in this study.
T66 1206-1413 Sentence denotes The residualized change score (i.e., trend) for each behavior was then estimated as the average of each participant’s residual score (i.e., the difference between the estimated value and the observed value).
T67 1414-1570 Sentence denotes A positive residualized change score indicates an increase in the specific behavior from the time before COVID-19 and a negative score indicates a decrease.
T68 1571-1803 Sentence denotes For each residualized change score, we explored the predictive role of a series of sociodemographic factors a priori thought to have influenced changes in the behaviors herein assessed after ECEC and school closures due to COVID-19.
T69 1804-1905 Sentence denotes We adjusted all models for age and sex of the child, family income, presence of lockdown, and region.
T70 1906-1994 Sentence denotes Data preparation and validation was conducted with Stata 15.0 (College Station, TX, USA:
T71 1995-2120 Sentence denotes StataCorp LLC), while analyses were conducted in R (version 3.5.2) (R Foundation for Statistical Computing, Vienna, Austria).
T72 2121-2185 Sentence denotes The level of significance was set at usual p < 0.05, two-tailed.
