Table 3. Serum levels of homocysteine and its vitamin determinants in pregnant women who were sleep deprived (case group) and who had adequate sleep (control group).

Variables	Control group (n=38)	Case group (n=30)	p-value
Folate (ng/mL)	8.2±6.3	7.7±4.1	0.063
Vitamin B12 (pg/mL)	220.8±85.4	219.5±65.4	0.947
Homocysteine (µmol/L)	11.1±2.2	13.9±7*	0.045*

*p<0.050 when compared with pregnant women with adequate sleep using Student’s t-test and Mann-Whitney U test for parametric and nonparametric data, respectively.
