“…Risk for operative delivery (eg, cesarean section) due to obstructed labor has long been associated with variation in maternal height (Baird, 1949(Baird, , 1965Konje & Ladipo, 2000;Merchant, Villar, & Kestler, 2001;Mogren et al, 2018;Stulp, Verhulst, Pollet, Nettle, & Buunk, 2011;Van Roosmalen & Brand, 1992). Shorter women are more likely to experience disproportion between dimensions of the pelvic canal and fetal body (Aitken & Walls, 1986;Toh-adam, Srisupundit, & Tongsong, 2012;Tsu, 1992), despite some evidence for a protective effect of maternal height-pelvic shape covariance (Fischer & Mitteroecker, 2015;Kurki, 2007).…”

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.

“…This analysis examines the relationship between fetal mortality (early fetal death and stillbirth), pregnancy order, maternal age and previous fetal deaths in a population characterized by high fertility and mortality and the virtual absence of obstetric and other medical care. Most studies indicate that fetal and infant mortality are highest among first pregnancies, lowest among second and third, and increase in pregnancy orders four and above (Alberman, 1974;Baird, 1965;Baxi, 1957;Bierman & French, 1965;Butler & Bonham, 1963;Chase, 1974;Heady & Daly, 1955;Mettal, 1970). Several studies indicate that this relationship between mortality and pregnancy order diminishes after adjustment for age of the mother (Chowdhury, 1975;Feldstein, 1966), for risks of fetal and infant mortality are highest among the youngest (16 and under) and older groups of mothers (35+) and lowest in women between the ages of 20 and 25 (Baxi, 1957;Butler & Bonham, 1963;Chase, 1974;Chen et al, 1974).…”

SummaryIn rural Bangladesh, early fetal wastage and stillbirth are higher among pregnancy orders one and six or higher than among orders two and three. The increased risk is particularly apparent among those pregnancies following two or more previous fetal deaths. Woman in the higher pregnancy orders who have not experienced previous fetal deaths or only one fetal death have only a slight increase in the risk of fetal death compared to women in pregnancy orders two and three. The virtual absence of obstetric care and the high maternal mortality in this Bengali population may allow only woman without reproductive impairmetns to reach the higher pregnancy orders.
