Statistical analyses were performed using IBM SPSS Statistics, v27. Participants included in our analysis were (a) characterized using descriptive statistics, and (b) compared two ways (“In Lockdown” vs. “Not in Lockdown” and “Prior to any Lockdown” vs. “During or Following any Lockdown”) using independent sample t-tests or Mann Whitney U Tests (continuous variables) and Chi-square tests (categorical variables) as appropriate. Similarly, we conducted analysis to determine whether outcomes differed in participants located in an LGA of concern compared with those not located in an LGA of concern.
Qualitative data were uploaded to NVivo software v12 (QSR International Pty Ltd) for management and coding. For this sub-study, comments related to COVID-19 were identified and extracted from the interview transcripts by the interviewer. Interviews were not categorized by whether or not they were conducted during lockdowns, as participants described their experiences across the postnatal period, rather than at a single timepoint (or “during the last week”). De-identified extracts are included to provide depth to the findings from the quantitative analysis.
