Concentrations of folate and vitamin B12 biomarkers in cases and controls according to birth statusa
| Biomarker | SGA birth | pb | Prematurity | pc | ||
|---|---|---|---|---|---|---|
| Cases (n = 16) | Controls (n = 229) | Cases (n = 15) | Controls (n = 231) | |||
| Plasma folate (ng/ml) | 10.08 ± 4.54 | 13.64 ± 5.44 | 0.011 | 10.28 ± 5.47 | 13.59 ± 5.40 | 0.022 |
| RBC folate (ng/ml) | 765.58 ± 270.51 | 768.02 ± 311.92 | 0.976 | 740.97 ± 311.78 | 767.36 ± 307.45 | 0.749 |
| Vitamin B12 (pg/ml) | 808.67 ± 306.38 | 775.72 ± 341.17 | 0.707 | 732.50 ± 311.44 | 783.78 ± 339.79 | 0.570 |
aAll values are mean ± SD. N represents the number of subjects with data available. SGA defined as, 10th customised birth weight percentile. Prematurity defined as a live birth with a gestational age <37 weeks gestation. The numbers of case and control subjects vary slightly because of missing values for some variables. bp values between SGA and non-SGA births, by independent samples t test between the two groups. cp values between prematurity and non-prematurity births, by independent samples t test between the two groups.
