Obesity prior to pregnancy found to increase risk of autism, according to new study

(Natural News) Being obese before getting pregnant has been found to increase the chance of having a child with autism, according to a study. The study, conducted by researchers at Northwestern University, found that mothers whose waists were at least 80 centimeters (cm) before pregnancy had a 65 percent higher chance of giving birth to a child...

CONCLUSION: Lower maternal postpartum plasma LDL concentration was associated with increased odds of ASD in offspring among children born to overweight and obese mothers. Our findings suggest that both maternal BMI and lipids should be considered in assessing their role in offspring ASD risk; and additional longitudinal studies are needed to better understand maternal lipid dynamics during pregnancy among normal weight and overweight/obese mothers.

Abstract Obesity as determined by BMI is a confounder in clinical evaluations of the effects of endocrine disrupting chemicals (EDCs). Validated regulatory tests are used to determine whether a chemical acts via a mode of action (MOA) that affects estrogen, androgen, thyroid or steroidogenic pathways. Test batteries for evaluating EDCs include QSAR, in vitro assays, and animal testing. Studies suggest that EDCs pose the greatest risk during prenatal and early infant development when organ systems are developing. Health effects include lowered fertility, endometriosis, and cancers associated with estrogenic activit...

Abstract Intestinal alkaline phosphatase (IAP) is an endogenous enzyme that promotes gastrointestinal homeostasis by detoxifying inflammatory mediators, tightening the gut barrier and promoting a healthy microbiome. Oral IAP administration was efficacious in ameliorating diabetes in a high fat diet (HFD) induced murine model. In humans, maternal obesity and diabetes during pregnancy has been associated with an increased risk of autism spectrum disorders (ASD). In mice, HFD-induced maternal obesity lead to offspring with cognitive deficiency. Here we investigated whether IAP administration to obese dams could ameli...

AbstractObjectiveTo evaluate the long-term pediatric neuropsychiatric morbidity of children born to obese patients.Study designA population-based cohort analysis was performed comparing all deliveries of obese (maternal pre-pregnancy body mass index of 30  kg/m2 or more) and non-obese patients between 1991 and 2014 at a single tertiary medical center. Hospitalizations of the offspring up to the age of 18  years involving neuropsychiatric morbidities were evaluated according to a pre-defined set of ICD-9 codes, including autistic, eating, sleeping and movement disorders, cerebral palsy, developmental disorders, an...

ConclusionOur findings support increased paternal BMI negatively affecting pregnancy and child health outcomes. Future studies must include or adjust for paternal contributions, as the longstanding assumption that only maternal factors are relevant is likely to have considerably confounded prior work.

Authors: Brodowski L, Büter W, Kohls F, Hillemanns P, von Kaisenberg C, Dammann O Abstract Maternal overweight and obesity are prenatal risk factors for obstetrical complications, preterm birth, neonatal morbidity as well as cognitive and behavioural developmental disorders in children. Paediatric morbidity and mortality as well as child development disorders are significantly associated with maternal obesity. Particularly in the neurodevelopmental and psychiatric area, it is becoming increasingly clear that, in children of mothers with an increased body mass index (BMI), there is a high correlation with child...

We examined small study effects and excess significance. We did analyses under credibility ceilings. This review is registered with PROSPERO, number CRD42018091704.Findings46 eligible articles yielded data on 67 environmental risk factors (544 212 cases, 81 708 787 individuals) and 52 biomarkers (15 614 cases, 15 433 controls). Evidence of association was convincing for maternal age of 35 years or over (relative risk [RR] 1·31, 95% CI 1·18–1·45), maternal chronic hypertension (odds ratio [OR] 1·48, 1·29–1·70), maternal gestational hypertension (OR 1·37,...

Publication date: Available online 15 March 2019Source: Neurochemistry InternationalAuthor(s): Roger Maldonado-Ruiz, Lourdes Garza-Ocañas, Alberto CamachoAutism spectrum disorder (ASD) is a complex neurodevelopmental disease which involves functional and structural defects in selective central nervous system (CNS) regions harming capability to process and respond to external stimuli. In addition to genetic background, etiological causes of ASD have not been fully clarified. Maternal immune activation (MIA) during pregnancy have been proposed as a potential etiological cause leading to aberrant synaptic pruning and m...

AbstractStudies have examined the association between parental body mass index (BMI) and autism spectrum disorder (ASD) in offspring, with inconsistent results, especially regarding maternal obesity, overweight and underweight. Cochrane Library, EMBASE, PubMed and PsycINFO databases were searched up to March 2018 for relevant observational studies with no language restriction. Our literature search identified 13 eligible studies for meta-analysis (involving 943,293 children and 30,337 cases). For maternal BMI (13 studies), both maternal obesity [OR 1.41 (95% CI 1.19 –1.67)] and maternal overweight [OR 1.16 (95% CI 1....
