TABLE 3.
Enrichment of 57Fe in cord blood following maternal ingestion during the third trimester of pregnancy among women who were obese and nonobese prepregnancy1
| Variable | Obese women (n = 20) | Nonobese women (n = 22) | P value |
|---|---|---|---|
| Enrichment in cord blood, Δ%2,3 | 3.16 (2.63–3.80) | 3.09 (2.63–3.72) | 0.90 |
| Maternal ingested Fe tracer present in neonate at birth, %4 | 6.13 (4.57–7.68) | 5.57 (4.05–7.09) | 0.61 |
1
Data are presented as standard least squares means (95% CIs) from generalized linear models (proc GLM). Δ% enrichment in cord blood was controlled for marital status. Statistical significance was set at P < 0.05. Analysis was run from whole cord blood samples. Fe, iron.
2
Percent excess was adjusted for the natural abundance of isotope administered (0.02,317 for 57/56Fe).
3
Data are presented as geometric least squares means (95% CIs).
4
Quantity of tracer dose in neonate divided by average tracer dose administered to mother.
