“…(19) indicated that a 3400‐g baby in the vertex position could pass through a pelvis with an obstetric conjugate of 10 cm. The mean birthweight of Malawian adolescents (2688 g) was well below this value, confirming the view (21, 22) that the effects of nutritional supplementation would need to be many fold greater before the risk of CPD would be increased. The evidence for adolescents who are better nourished and who have larger babies suggests a lower incidence of CPD compared with older women (23).…”

“…Using X-ray pelvimetry, Joyce et al (19) indicated that a 3400-g baby in the vertex position could pass through a pelvis with an obstetric conjugate of 10 cm. The mean birthweight of Malawian adolescents (2688 g) was well below this value, confirming the view (21,22) that the effects of nutritional supplementation would need to be many fold greater before the risk of CPD would be in-creased. The evidence for adolescents who are better nourished and who have larger babies suggests a lower incidence of CPD compared with older women (23).…”

“…Based on this evidence it is doubtful that, “interventions to increase fetal growth in these circumstances might result in worse, rather than better, maternal and child health” 11 . Whereas the change in head size and therefore delivery risk is not significantly changed, the benefit of nutritional supplementation to maternal nutritional status and fetal growth during pregnancy and the benefits derived later during lactation are well documented 26 . Stunted growth has long been recognised as a consequence of chronic under nutrition and poor health.…”

Objective To estimate the changes in risk of intrapartum caesarean delivery and perinatal distress that may be introduced through increased birth size, resulting from interventions such as improving nutrition of the mother; and to characterise delivery risk relative to maternal stature by birth size. Design Model these risks using data from the Guatemalan Perinatal Study. Setting The antenatal clinic of the Gynaecology and Obstetrics Hospital of the Guatemalan Social Security Institute in Guatemala City serving predominantly working class women. Population Women who had their first prenatal visit between April 1984 and January 1986. Methods Multivariate logistic regression models were developed to estimate incidence of intrapartum caesarean delivery and perinatal distress and used to calculate changes in risk associated with changes in size. Main outcome measures Incidences of intrapartum caesarean delivery and perinatal distress. Results A woman of 146cm height (‐1 SD) relative to another of 160cm (+1 SD) has a 2.5 times higher risk of intrapartum caesarean delivery. An increase in newborn head circumference and weight (from ‐1 SD to +1 SD) are each independently associated with an increase in risk of intrapartum caesarean delivery (2.0 times and 1.5 times, respectively). An increase in birthweight from 2,450 g to 2,550 g is associated with a decrease in risk of perinatal distress of 34/1000 cases and an increase in risk of intrapartum caesarean delivery of 8/1000 cases. Conclusions Increases in fetal growth comparable to those attributable to improved nutrition during pregnancy are associated with a larger decrease in risk of perinatal distress relative to the increase in risk of intrapartum caesarean delivery for the mother. Greater maternal stature is associated with lower risk of intrapartum caesarean delivery.
