- CI confidence interval, RRR crude relative risk ratio, aRRR adjusted relative risk ratio, AGA appropriate for gestational age, LGA large for gestational age, SGA small for gestational age
- Group 1 = health conscious; Group 2 = body-shape and health conscious; Group 3 = not body-shape or health conscious
- aRRR1: Adjusted maternal characteristics included age, pre-pregnancy body mass index, marital status, parity, educational level, weight loss methods, total energy intake, physical activity, smoking and alcohol consumption habit, past medical history (anaemia, hypertension, diabetes), previous caesarean delivery, pregnancy-related nausea and vomiting, and receipt of health guidance
- aRRR2: Adjusted for gestational weight gain in addition to maternal characteristics adjusted in aRRR1
