Results are reported from a nutritional questionnaire completed by 422 South Auckland women during late pregnancy. Participants reported ethnicity as Māori (24.2%), Pacific (40.5%), Asian (12.8%) and European/Others (21.8%). Most (95.0%) reported receiving information about healthy eating while pregnant and 61% reported eating healthy foods frequently or very frequently. Nearly half (44.3%) reported eating more in pregnancy; the commonest reasons were cravings and ‘eating for two’. In a multivariable logistic regression analysis adjusting for ethnicity and gestation, the self-reported factors associated with infrequent healthy eating in this sample were Māori (adjusted OR 17.66; 95% CI, 8.49 to 36.77) and Pacific ethnicity (aOR 14.54; 95% CI, 7.32 to 28.88); parity ≥3 (aOR 2.09; 95% CI, 1.26 to 3.48); obesity (aOR 2.84; 95% CI, 1.35 to 5.97); unplanned pregnancy (aOR 1.95; 95% CI, 1.18 to 3.22); and eating takeaways ≥3 times/week (aOR 4.46; 95% CI, 1.88 to 10.56). The majority (83.4%) of the sample stated that they would likely/very likely participate in a nutritional intervention.
