Data are presented as means (standard deviations) unless otherwise indicated. Data were missing for 2 participants for birth weight and for 3 participants for maternal self-reported BMI. P values were not calculated for baseline measurements, as the groups are randomized. Abbreviations: BLISS, Baby-Led Introduction to SolidS; BMI, body mass index (calculated as weight in kilograms divided by height in meters squared).
School or postschool only includes primary school, secondary school, trade, certificates, and diplomas.
Determined using the 2013 New Zealand index of deprivation (47). The index combines 9 variables from the 2013 New Zealand National Census to provide a deprivation score for each mesh block (a geographical unit defined by Statistics New Zealand that contains approximately 81 people). The score reflects the extent of material and social deprivation and is used to construct deciles from 1 (low deprivation) to 10 (high deprivation).
