Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with poorly understood etiology. Many maternal exposures during pregnancy and breastfeeding potentially interfere with neurodevelopment. Using data from two age- and sex-matched case-control studies in Jamaica (n = 298 pairs), results of conditional logistic regression…

Fairthorne, Jenny; Hammond, Geoff; Bourke, Jenny; de Klerk, Nick; Leonard, Helen – Journal of Autism and Developmental Disorders, 2016
Psychiatric disorders are more common in the mothers of children with autism spectrum disorder (ASD) or intellectual disability (ID) after the birth of their child. We aimed to assess the relationship between women's psychiatric contacts and subsequent offspring with ASD/ID. We linked three Western Australian registers to investigate pre-existing…

Grønborg, Therese K.; Hansen, Stefan N.; Nielsen, Svend V.; Skytthe, Axel; Parner, Erik T. – Journal of Autism and Developmental Disorders, 2015
Stoppage refers to changes in reproductive behavior following the birth of a child with a severe disease. The presence of stoppage can bias estimates of sibling recurrence risk if not properly addressed. If stoppage occurs non-randomly (differential stoppage), it is possibly an additional source of bias in sibling recurrence risk estimation. This…

Timonen-Soivio, Laura; Sourander, Andre; Malm, Heli; Hinkka-Yli-Salomäki, Susanna; Gissler, Mika; Brown, Alan; Vanhala, Raija – Journal of Autism and Developmental Disorders, 2015
The aim of this study was to evaluate the association between autism spectrum disorders (ASD) with and without intellectual disability (ID) and congenital anomalies (CAs) by organ system. The sample included all children diagnosed with ASD (n = 4441) from the Finnish Hospital Discharge Register during 1987-2000 and a total of four controls per…

Gidaya, Nicole B.; Lee, Brian K.; Burstyn, Igor; Yudell, Michael; Mortensen, Erik L.; Newschaffer, Craig J. – Journal of Autism and Developmental Disorders, 2014
We investigated whether there is an association between increased risk for autism spectrum disorders (ASD) and selective serotonin reuptake inhibitors (SSRIs) used during pregnancy. This study used Denmark's health and population registers to obtain information regarding prescription drugs, ASD diagnosis, and health and socioeconomic status. There…

Dodds, Linda; Fell, Deshayne B.; Shea, Sarah; Armson, B. Anthony; Allen, Alexander C.; Bryson, Susan – Journal of Autism and Developmental Disorders, 2011
We conducted a linked database cohort study of infants born between 1990 and 2002 in Nova Scotia, Canada. Diagnoses of autism were identified from administrative databases with relevant diagnostic information to 2005. A factor representing genetic susceptibility was defined as having an affected sibling or a mother with a history of a psychiatric…

Lee, Brian K.; Gardner, Renee M.; Dal, Henrik; Svensson, Anna; Galanti, Maria Rosaria; Rai, Dheeraj; Dalman, Christina; Magnusson, Cecilia – Journal of Autism and Developmental Disorders, 2012
Prenatal exposure to tobacco smoke is suggested as a potential risk factor for autism spectrum disorders (ASD). Previous epidemiological studies of this topic have yielded mixed findings. We performed a case-control study of 3,958 ASD cases and 38,983 controls nested in a large register-based cohort in Sweden. ASD case status was measured using a…

This article presents an overview of the Finnish Prenatal Study of Autism and Autism Spectrum Disorders (FIPS-A), a new study designed to examine the relationship between prenatal serologic factors, mediating and moderating developmental antecedents, and risk of autism spectrum disorders (ASD). The FIPS-A is based on register linkages between…

Atladottir, Hjordis O.; Thorsen, Poul; Ostergaard, Lars; Schendel, Diana E.; Lemcke, Sanne; Abdallah, Morsi; Parner, Erik T. – Journal of Autism and Developmental Disorders, 2010
Exposure to prenatal infection has been suggested to cause deficiencies in fetal neurodevelopment. In this study we included all children born in Denmark from 1980, through 2005. Diagnoses of autism spectrum disorders (ASDs) and maternal infection were obtained through nationwide registers. Data was analyzed using Cox proportional hazards…

Li, Jiong; Olsen, Jorn; Obel, Carsten; Christensen, Jakob; Precht, Dorthe Hansen; Vestergaard, Mogens – Journal of Autism and Developmental Disorders, 2009
We aimed to examine whether exposure to prenatal stress following maternal bereavement is associated with an increased risk of febrile seizures. In a longitudinal population-based cohort study, we followed 1,431,175 children born in Denmark. A total of 34,777 children were born to women who lost a close relative during pregnancy or within 1 year…

We conducted a case-control study using 190 Han children with and without autism to investigate prenatal and perinatal risk factors for autism in China. Cases were recruited through public special education schools and controls from regular public schools in the same region (Tianjin), with frequency matching on sex and birth year. Unadjusted…
