Comparisons of plasma levels of micronutrients between day eaters and night eaters (n = 852) at 26–28 weeks gestation.

	Day Eaters (n = 730)	Night Eaters (n = 122)
Plasma Nutrients	Mean ± SE	Mean ± SE	p-Value
Vitamin B6, nmol/L	78.0 ± 2.7	64.2 ± 8.0	0.107
Vitamin B12, pmol/L	299.7 ± 5.1	272.9 ± 15.2	0.126
Folate, nmol/L	17.3 ± 0.9	13.4 ± 2.7	0.010
Vitamin D (25OHD), nmol/L	78.4 ± 1.2	71.3 ± 3.7	0.025
Ferritin, ng/mL	26.1 ± 0.6	28.7 ± 1.7	0.079

Data were drawn from the Growing Up in Singapore Towards Healthy Outcomes study and analyzed using general linear models, adjusting for maternal age, ethnicity, educational level, early pregnancy body mass index and total daily energy intake. All nutrients were log-transformed for analysis. Day eaters, consumption of ≥50% of total daily energy intake between 7:00 a.m. and 6:59 p.m.; night eaters, consumption of >50% of total daily energy intake between 7:00 p.m. and 6:59 a.m.; SE, standard error; 25OHD, 25-hydroxyvitamin D. p-Value was based on independent t-test, p < 0.05 indicates statistical significant.
