Trevathan, Ph.D. Date of Approval March 11, 2021 Keywords: Homebirth, Physiological Normal Birth, Evolutionary Medicine, Cortisol, Obligate Midwifery Copyright © 2021, Nicole Loraine Falk Smith DEDICATION In loving memory of my Mother, Linda, a free spirit. When I struggled, she would tell me that we were pebbles in a stream. That sometimes we’d get caught in a little whirlpool and we would stay awhile. Eventually, the current would carry us on, so don’t fight the current, she’d say, let it take you where you belong. ACKNOWLEDGMENTS I am so thankful to all the people who supported me in this endeavor and those who continued to encourage me on my worst of days. First, I want to thank the mothers and the midwives who participated in this study. Truly, the best part of conducting this research was talking to you. I enjoyed meeting you, especially those who invited me into their homes and let me hold their new born babies. Next, I want to thank Lorena Madrigal. Lorena has been a role model and an inspiration to me since I first met her almost 20 years ago. It is an honor to earn my PhD with you as my major professor. I also want to thank my committee members, David, Elizabeth, Linda, and Wenda. Thank you for your support, patience, and insight. I want to thank my father, Duane. Down every path I have taken, he has always been there for me. He has probably read more of my writing than anyone else. When I took my first college class and received a B, he said “always ‘B’ yourself.” I still live by those simple words. My mom, who I dedicated this work to, was an amazing woman. I miss talking to her dearly. When I was a girl, I struggled to read due to dyslexia, but with a mother’s love, I persisted. My dearest friends, Sara, Leslie, Janet, Etel, and Kimberly, thank you for your friendship. We have seen each other through a lot and I couldn’t have made it through without you. Finally, I thank my daughter, Dwana. You are a blessing beyond all blessings to me. You are wise beyond your years. Thank you for your understanding and encouragement as I worked through this writing process.

  • Human Variation in Pelvic Shape and the Effects of Climate and Past
    Human variation in pelvic shape and the effects of climate and past population history Lia Betti Centre for Research in Evolutionary, Social and Inter-Disciplinary Anthropology, Department of Life Sciences, University of Roehampton, London, SW15 4JD, UK. Email: [email protected] Tel: +44 (0)20 8392 3650 Running title: pelvic variation, climate and genetic drift ABSTRACT The human pelvis is often described as an evolutionary compromise (obstetrical dilemma) between the requirements of efficient bipedal locomotion and safe parturition of a highly encephalized neonate, that has led to a tight fit between the birth canal and the head and body of the foetus. Strong evolutionary constraints on the shape of the pelvis can be expected under this scenario. On the other hand, several studies have found a significant level of pelvic variation within and between human populations, a fact that seems to contradict such expectations. The advantages of a narrow pelvis for locomotion have recently been challenged, suggesting that the tight cephalo-pelvic fit might not stem from the hypothesized obstetrical dilemma. Moreover, the human pelvis appears to be under lower constraints and to have relatively higher evolvability than other closely related primates. These recent findings substantially change the way in which we interpret variation in the human pelvis, and help make sense of the high diversity in pelvic shape observed within and among modern populations. A lower magnitude of covariance between functionally important regions ensured that a wide range of morphological variation was available within populations, enabling natural selection to generate pelvic variation between populations living in different environments.

To the rest of my thesis committee, Professor Karakasidou and Professor Imber, for your insightful comments and valuable feedback. To Wellesley Career Education, who funded my internship at the Maxwell Museum of Anthropology’s Osteology Laboratory and the Office of Archaeological Studies. Without the opportunity to work there, I would never have had the chance to study the Maxwell’s Documented Skeletal Collection. To the Maxwell Museum’s Osteology Laboratory, for allowing me to work with the Documented Skeletal Collection, without which, this thesis would not be possible.

  • 1 Immature Pelvic Growth and Obesity: a Biocultural Analysis of Risks
    Immature pelvic growth and obesity: A biocultural analysis of risks associated with adolescent pregnancy in the U.S. by Emma Ronayne Anthropology Degree, from the University of Victoria, 2020 An Essay Submitted in Partial Fulfillment of the Requirements of the HONOURS PROGRAM in the Department of Anthropology © Emma Ronayne, 2020 University of Victoria All rights reserved. This thesis may not be reproduced in whole or in part, by photocopy or other means, without the permission of the author. 1 Abstract Adolescent pregnancy in women aged 10-19 years is associated with higher rates of adverse outcomes for both the mother and infant than adult pregnancy. Health conditions and immaturities such as obesity and immature pelvic growth compound the associated risks of adolescent pregnancy. Black and Indigenous women in the U.S. experience disproportionately high rates of adolescent pregnancy and obesity. This research project aims to answer two questions: (1) What are the contributing risks of pelvic immaturity and obesity on adverse outcomes in adolescent pregnancy, especially in the U.S.?; and (2) Why are Black and Indigenous women at particular risk of adolescent pregnancy and obesity in the U.S.? In this research project, I have conducted statistical analyses of the biological and social factors associated with adolescent pregnancy using the CDC WONDER database, and I have used case studies and ethnographic accounts to understand Black and Indigenous women’s experiences with adolescent pregnancy. In this essay, I examine the racial disparities in rates of adolescent pregnancy, obesity and adverse outcomes in the U.S. I focus on biological risks associated with adolescent pregnancy and the social factors associated with the most at-risk groups for adolescent pregnancy and obesity.

  • Obstetrical Dilemma’: Stunting, Obesity and the Risk of Obstructed Labour
    CORE Metadata, citation and similar papers at core.ac.uk Page 1 of 55 Provided by UCL Discovery The new ‘obstetrical dilemma’: stunting, obesity and the risk of obstructed labour Jonathan CK Wells UCL Institute of Child health 30 Guilford Street London WC1N 1EH [email protected] 1 Page 2 of 55 1 Abstract 2 The ‘obstetrical dilemma’ refers to the tight fit between maternal pelvic dimensions and 3 neonatal size at delivery. Most interest traditionally focused on its generic significance for 4 humans, for example our neonatal altriciality and our complex and lengthy birth process. 5 Across contemporary populations, however, the obstetrical dilemma manifests substantial 6 variability, illustrated by differences in the incidence of cephalo-pelvic disproportion, 7 obstructed labour and cesarean section. Beyond accounting for 12% of maternal mortality 8 worldwide, obstructed labour also imposes a huge burden of maternal morbidity, in 9 particular through debilitating birth injuries. This paper explores how the double burden of 10 malnutrition and the global obesity epidemic may be reshaping the obstetrical dilemma. 11 First, short maternal stature increases the risk of obstructed labour, while early age at 12 marriage also risks pregnancy before pelvic growth is completed. Second, maternal obesity 13 increases the risk of macrosomic offspring. In some populations, short maternal stature may 14 also promote the risk of gestational diabetes, another risk factor for macrosomic offspring. 15 These nutritional influences are furthermore sensitive to social values relating to issues such 16 as maternal and child nutrition, gender inequality and age at marriage. Secular trends in 17 maternal obesity are substantially greater than those in adult stature, especially in low- and 18 middle-income countries.
