Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 06/10/2025: 1. Between-group difference in mean weight change (kg) from baseline to 6 months and baseline to 24 months, respectively. 2. Between-group difference in mean waist circumference (cm) measured by a flexible measuring tape at baseline, 6, 12 and 24 months. 3. Between-group difference in mean BMI (kg/m2) measured at baseline, 6, 12 and 24 months. 4. Between-group difference in proportions of women: i) gaining a substantial amount of weight (5 kg) at 12 and 24 months; ii) losing a substantial amount of weight (5 kg) between 12 and 24 months; iii) who have returned to their pre-pregnancy weight at 24 months; iv) who maintained a weight loss between 12 and 24 months. 5. Health behaviours are measured by: Fat and Fibre Barometer; self-report questionnaire on sugar and alcohol intake; International Physical Activity Questionnaire (IPAQ) - Short form; and self-report questionnaire on infant feeding practices (Infant Feeding Survey) measured at baseline, 6, 12 and 24 months 6. Study acceptability is measured by: recruitment; retention; engagement with the two-way text messages during 12 months; self-reported questionnaire on participant satisfaction with SMS messages (at 6 and 12 months) and rating of intervention (at 12 months); and qualitative interviews (at 6 and 12 months), 7. Economic evaluation outcomes are measured by: self-report questionnaire on health service resources use, prescribed and over-the counter medication usage and lifestyle-related costs; the EuroQol 5-dimension (EQ-5D-5L with visual analogue scale) quality of life questionnaire; and the ICEpop Capability Measure for Adults (ICECAP-A) at baseline, 6, 12 and 24 months 8. Moderators of intervention effect are measured by: Edinburgh Postnatal Depression Scale (EPDS); Generalised Anxiety Disorder (GAD-7); Pittsburgh Sleep Quality Index; and self-report questionnaire on confidence and desire for weight loss and maintenance at baseline, 6, 12 and 24 months 9 | — |
