Cortisol, glucose, and insulin levels in maternal and fetal plasma of control (C) and maternal nutrient reduction (MNR) groups. These parameters were determined in maternal and fetal plasma of control ad libitum-fed pregnancies and in the presence of MNR, characterized as 70% of the food consumed by control mothers on a weight-adjusted basis of baboons at 0.9 gestation. A: cortisol levels in maternal and fetal plasma of control and MNR baboons (male fetuses: n = 3; female fetuses: n = 3). C-M, male fetuses from the control group; C-F, female fetuses from the control group; MNR-M, male fetuses from the MNR group; MNR-F, female fetuses from the MNR group. B: glucose levels in maternal and fetal plasma of control and MNR (n = 6) baboons (male fetuses: n = 3; female fetuses: n = 3). C: insulin levels in maternal and fetal plasma of control and MNR baboons (male fetuses: n = 3; female fetuses: n = 3). Values are means ± SE; n = 3 (when separated by sex) or 6 (sexes combined) animals/group. *P < 0.05 vs. the respective controls.
