Both human epidemiologic and animal model studies demonstrate that prenatal and lactational exposure to maternal obesity and high-fat diet are associated with adverse neurodevelopmental outcomes in offspring. Neurodevelopmental outcomes described in offspring of obese women include cognitive impairment, autism spectrum disorder (ASD), attention deficit hyperactivity disorder, anxiety and depression, disordered eating, and propensity for reward-driven behavior, among others. This review synthesizes human and animal data linking maternal obesity and high-fat diet consumption to abnormal fetal brain development, and neurodevelopmental and psychiatric morbidity in offspring. It highlights key mechanisms by which maternal obesity and maternal diet impact fetal and offspring development, and sex differences in offspring programming. In addition, we review placental effects of maternal obesity, and the role the placenta might play as an indicator vs mediator of fetal programming.


Perinatal exposure to maternal obesity: Lasting cardiometabolic impact on offspring
Kışlal, Sezen; Edlow, Andrea G. (2020-08-01)
Evidence from epidemiological, clinical, and animal model studies clearly demonstrates that prenatal and lactational maternal obesity and high-fat diet consumption are associated with cardiometabolic morbidity in offspring. Fetal and offspring sex may be an important effect modifier. Adverse offspring cardiometabolic outcomes observed in the setting of maternal obesity include an increased risk for obesity, features of metabolic syndrome (hypertension, hyperglycemia and insulin resistance, hyperlipidemia, i...
Maternal and Perinatal Outcomes of White Coat Hypertension During Pregnancy A Systematic Review and Meta-Analysis
Johnson, Sonia; Liu, Becky; Kalafat, Erkan; Thilaganathan, Basky; Khalil, Asma (Ovid Technologies (Wolters Kluwer Health), 2020-07-01)
The aim of this meta-analysis is to investigate whether white-coat hypertension (WCH) has an adverse effect on maternal, fetal, and neonatal outcomes. Medline, EMBASE,, and Cochrane Library databases were searched electronically in December 2019. The outcomes were compared between pregnant women with WCH and normotensive controls, women with chronic hypertension, gestational hypertension or any hypertensive disorder of pregnancy. Twelve studies were eligible for inclusion in the systematic review. Women wit...
Mismatch between obesogenic intrauterine environment and low-fat postnatal diet may confer offspring metabolic advantage
Kışlal, Sezen; Maesner, Claire; Edlow, Andrea G. (2021-08-01)
Objective: Mismatch between a depleted intrauterine environment and a substrate-rich postnatal environment confers an increased risk of offspring obesity and metabolic syndrome. Maternal diet-induced obesity (MATOB) is associated with the same outcomes. These experiments tested the hypothesis that a mismatch between a nutrient-rich intrauterine environment and a low-fat postnatal environment would ameliorate offspring metabolic morbidity.
Control and manipulation of life : a critical assessment of genetics through the perspectives of Hans Jonas, Martin Heidegger and Michel Foucault
Bilginer, Onur; Deveci, Cem; Department of Political Science and Public Administration (2006)
This study is on the political and ethical aspects of recent advances in genetics. Its aim is to explicate the scientific and technological premises of genetics along historical, philosophical and political axes by employing the critical perspectives of Jonas, Heidegger and Foucault. Starting the discussion from a brief account of scientific and technological revolutions initiated in the 16th and 17th centuries, I defend the thesis that the idea of control and manipulation of life is not a novelty introduce...
Determinants of healthy eating behaviours among middle school students: the theory of planned behaviour approach
Bilim, İbrahim; Öztekin, Ceren; Department of Elementary Science and Mathematics Education (2015)
This study was conducted in attempt to integrate a number of cognitive and motivational factors in healthy eating domain and to develop a structural model that might explain young students’ healthy eating intentions and behaviors. Founded on the theory of planned behavior framework, the current study explored the interrelationships among students’ behavioral beliefs, control beliefs, normative beliefs, and attitudes toward behavior, subjective norms, perceived behavioral control (PBC), intentions, personal ...
