“…The question of whether pelvimetry (measurement of the female pelvis) is useful for predicting obstructed labor or operative delivery at the individual level has been assessed by a number of authors, with mixed results (Connolly & McKenna, 2001;Harper, Odibo, Stamilio, & Macones, 2013;Lenhard et al, 2010;Liselele, Boulvain, Tshibangu, & Meuris, 2000;Spörri et al, 2002;Sun & Tong, 2014;Thubisi, Ebrahim, Moodley, & Shweni, 1993;Zaretsky et al, 2005). A recent Cochrane systematic review determined there was not enough evidence in the literature to support the use of X-ray pelvimetry for predicting risk of obstructed labor and optimal mode of delivery (Pattinson, Cuthbert, & Vannevel, 2017).…”

Objectives Pelvic growth may be sensitive to early‐life nutrition, with implications for maternal risk of obstructed labor. However, the “developmental origins” of adult pelvic variability require further investigation. We tested whether adult pelvic dimensions are associated with two components of height, indexing different periods of linear growth: tibia length, a proxy for early postnatal growth, and height‐residual (height regressed on tibia length), a proxy for later growth. We also tested whether adult pelvic dimensions are associated with birth weight, a marker of nutritional investment in utero. Methods In this cross‐sectional study, data were obtained on 68 nulliparous young women of South Asian ancestry. Pelvic dimensions (bi‐iliac and bi‐acetabular breadth, anteroposterior pelvic inlet and outlet, interspinous and intertuberous diameter) were measured using magnetic resonance imaging. Height and tibia length were measured manually. Birth weight and gestational age were obtained by recall. Multivariable regression models were fitted with a given pelvic dimension regressed on height‐residual, tibia, and birth weight, with the latter adjusted for gestational age. Results Controlling for birth weight, height‐residual was predictive of bi‐acetabular breadth, bi‐iliac breadth, and the pelvic inlet, while tibia length significantly predicted all dimensions except interspinous diameter. Controlling for the linear growth variables, birth weight was predictive of bi‐iliac breadth only. Conclusions Markers of linear growth during both early and later development were associated with adult pelvic dimensions, whereas size at birth was poorly predictive. Efforts to reduce stunting in early life may facilitate the attainment of maximum potential growth for both height and the pelvis.

“…Maternal height correlates positively with her pelvic dimensions and is an important predictor of obstructed labor (Connolly and McKenna, 2001; Kjærgaard et al, 2010; Benjamin et al, 2012). Furthermore, in the “head and trunk skeletal size” PC, trunk breadths feature relatively prominently along with head size.…”

“…The stronger association between maternal anthropometry and head circumference compared with paternal anthropometry, and the exclusive association between the "head and trunk skeletal size" PC and maternal anthropometry, might reflect processes that serve to prevent a mismatch between fetal size and maternal birth canal dimensions that could otherwise result in obstructed labor (Pembrey, 1996). Maternal height correlates positively with her pelvic dimensions and is an important predictor of obstructed labor (Connolly and McKenna, 2001;Kjaergaard et al, 2010;Benjamin et al, 2012). Furthermore, in the "head and trunk skeletal size" PC, trunk breadths feature relatively prominently along with head size.…”

The patterns of association between maternal or paternal and neonatal phenotype may offer insight into how neonatal characteristics are shaped by evolutionary processes, such as conflicting parental interests in fetal investment and obstetric constraints. Paternal interests are theoretically served by maximizing fetal growth, and maternal interests by managing investment in current and future offspring, but whether paternal and maternal influences act on different components of overall size is unknown. We tested whether parents' prepregnancy height and body mass index (BMI) were related to neonatal anthropometry (birthweight, head circumference, absolute and proportional limb segment and trunk lengths, subcutaneous fat) among 1,041 Australian neonates using stepwise linear regression. Maternal and paternal height and maternal BMI were associated with birthweight. Paternal height related to offspring forearm and lower leg lengths, maternal height and BMI to neonatal head circumference, and maternal BMI to offspring adiposity. Principal components analysis identified three components of variability reflecting neonatal “head and trunk skeletal size,” “adiposity,” and “limb lengths.” Regression analyses of the component scores supported the associations of head and trunk size or adiposity with maternal anthropometry, and limb lengths with paternal anthropometry. Our results suggest that while neonatal fatness reflects environmental conditions (maternal physiology), head circumference and limb and trunk lengths show differing associations with parental anthropometry. These patterns may reflect genetics, parental imprinting and environmental influences in a manner consistent with parental conflicts of interest. Paternal height may relate to neonatal limb length as a means of increasing fetal growth without exacerbating the risk of obstetric complications. Am J Phys Anthropol 156:625–636, 2015.

“…It is a common ground in obstetrics to assume that the greater the maternal size the lower the likelihood of obstructed labor, irrespective of the actual fetal size. Indeed, the available data suggests a direct relationship between maternal height and size of the birth canal [28][29][30]. Furthermore, the use of customized growth charts allows to correlate the fetal size to maternal (or parental) [31][32][33][34] and is supposed to define which is the appropriate biometry of a specific fetus in relation to the maternal anthropometric features.…”
