BACKGROUND
Maternal dietary patterns during pregnancy have been shown to influence infant birth outcomes. However, to our knowledge, only a few studies have examined the associations in Asian populations.

OBJECTIVE
We characterized maternal dietary patterns in Asian pregnant women and examined their associations with the risk of preterm birth and offspring birth size.

DESIGN
At 26-28 wk of gestation, 24-h recalls and 3-d food diaries were collected from the women in the Growing Up in Singapore Towards healthy Outcomes mother-offspring cohort. Dietary patterns were derived from exploratory factor analysis. Gestational age was determined by a dating ultrasound scan in the first trimester, and infant birth anthropometric measurements were obtained from hospital records. Associations were assessed by logistic and linear regressions with adjustment for confounding factors.

RESULTS
Three maternal dietary patterns were identified: vegetable, fruit, and white rice (VFR); seafood and noodle (SfN); and pasta, cheese, and processed meat (PCP). Of 923 infants, 7.6% were born preterm, 13.4% were born small for gestational age, and 14.7% were born large for gestational age. A greater adherence to the VFR pattern (per SD increase in VFR score) was associated with a lower risk of preterm births (OR: 0.67; 95% CI: 0.50, 0.91), higher ponderal index (β: 0.26 kg/m(3); 95% CI: 0.06, 0.45 kg/m(3)), and increased risk of a large-for-gestational-age birth (RR: 1.31; 95% CI: 1.06, 1.62). No associations were observed for the SfN and PCP patterns in relation to birth outcomes.

CONCLUSIONS
The VFR pattern is associated with a lower incidence of preterm birth and with larger birth size in an Asian population. The findings related to larger birth size warrant further confirmation in independent studies.
