“…One is that the occurrence of neurodevelopmental outcomes may have differed in children participating in CATSS with completed A-TAC assessment and those in the general population. Two Swedish studies found that children of immigrant parents had impaired psychological health (Gillberg et al, 1987;Magnusson et al, 2012;Van Leeuwen et al, 2012); however, the occurrence of neurodevelopmental disorders in our study was lower in families with both parents from outside of Scandinavian countries. The data linkage to other registers allowed us to acquire additional data on the CATSS non-responders, which indicated that children enrolled in the study had higher familial socio-economic status.…”

Exposure to Air Pollution From Traffic and Neurodevelopmental Disorders in Swedish Twins

Background: Recent studies have reported associations between air pollution exposure and neurodevelopmental disorders in children, but the role of pre-and postnatal exposure has not been elucidated. Aim: We aimed to explore the risk for autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD) among children in relation to pre-and postnatal exposure to air pollution from road traffic. Methods: Parents of 3,426 twins born in Stockholm during 1992-2000 were interviewed, when their children were 9 or 12 years old, for symptoms of neurodevelopmental disorders. Residence time-weighted concentrations of particulate matter with a diameter <10 m (PM 10 ) and nitrogen oxides (NO x ) from road traffic were estimated at participants' addresses during pregnancy, the first year, and the ninth year of life using dispersion modeling, controlling for seasonal variation. Multivariate regression models were used to examine the association between air pollution exposure and neurodevelopmental outcomes, adjusting for potential confounding factors. Results: No clear or consistent associations were found between air pollution exposure during any of the three time windows and any of the neurodevelopmental outcomes. For example, a 5-95% difference in exposure to NO x during pregnancy was associated with odds ratios (ORs) of 0.92 (95% confidence interval (CI): 0.44-1.96) and 0.90 (95% CI: 0.58-1.40) for ASD and ADHD respectively. A corresponding range in exposure to PM 10 during pregnancy was related to ORs of 1.01 (95% CI: 0.52-1.96) and 1.00 (95% CI: 0.68-1.47) for ASD and ADHD. Conclusions: Our data do not provide support for an association between pre-or postnatal exposure to air pollution from road traffic and neurodevelopmental disorders in children.

“…100 According to a Swedish study, migrant parents from countries with a low ranking on a human development index may be at increased risk of having children with ASD and comorbid ID compared with Swedish-born parents, particularly when migration occurred around time of pregnancy, suggesting a possible link with maternal stress. 249 However, migrant parents from developing countries may have a decreased risk of having children with PDD-NOS or Asperger.…”

“…Maternal immigrant status is another social factor that emerged in eight studies 104,208,243,[247][248][249][250][251] and two systematic reviews 13,100 supporting an association with ASD or ASD subtype. Migrant mothers had a higher prevalence of offspring with ASD in studies from Sweden, the United Kingdom and Australia.…”

Introduction: The number of children diagnosed with autism spectrum disorder (ASD) has been rapidly rising in the past decade. The etiology of this disorder, however, is largely unknown, although the environmental relative to the genetic contribution is substantial. We conducted a scoping review to comprehensively assess the current state of knowledge of the environmental factors present from preconception to early life associated with ASD, and to identify research gaps.

“…Although the specific mechanisms behind childhood autism are largely unknown, risk factors include male sex [1], familial history of autism [1,2], advanced age in either parent at childbirth [3][4][5], neuropsychiatric disorders [6], perinatal complications [7], ethnic background and migration [8,9], and low socioeconomic status [7,10,11]. In addition to these individual-level factors, it is possible that certain social features of the neighborhood environment are associated with autism.…”
