Nutr Neurosci. Birth spacing and risk of autism and other neurodevelopmental disabilities: a systematic review. Epub 2017 Jul 14. Int J Environ Res Public Health. Wu et al. Martinez-Biarge M, et al. It has been proposed that fathers with autistic traits are more likely to marry immigrant women [57]. Autism is affecting more families now than ever – yet, the causes remain unknown. 2010;22(2):219–25. The authors observed significantly higher risk of ASD in the immigrants in three studies, whereas five studies showed no difference between immigrant and non-immigrant mothers, and two studies showed significantly lower risk of ASD in immigrants than that in non-immigrants. It has been suggested that the differential effect of testosterone on sexually dimorphic brain regions might be a key mechanism to push the brain beyond that of a typical male and toward an EMB. CAS  1995;39(Pt 2):141–4. MacGregor AJ, et al. Environ Health Perspect. Nutr Neurosci. Some experts suspect that exposure to heavy metals and other toxins in the environment raises your risk of ASD. Radaelli T, et al. The risk was precise but inconsistent. Compared to genetic studies of ASD, studies of environmental risk factors are in their infancy and have significant methodological limitations. A meta-analysis of the evidence on the impact of prenatal and early infancy exposures to mercury on autism and attention deficit/hyperactivity disorder in the childhood. The studies on toxic elements have been largely limited by their design, but there is enough evidence for the association between some heavy metals (most important inorganic mercury and lead) and ASD that warrants further investigation. Furthermore, it is difficult to establish causality from observational studies due to possibility of genetic and/or environmental confounding. Human stem cell-based models for studying autism spectrum disorder-related neuronal dysfunction. Environmental toxicants and autism spectrum disorders: a systematic review. Bandim JM, et al. Curr Med Chem. Biological underpinning of environmental risk factors of ASD are debated but might include non-causative association, gene-related effect, oxidative stress, inflammation, hypoxia/ischemia, endocrine disruption, neurotransmitter alterations, and interference with signaling pathways. J Child Neurol. The estimates were of small magnitude, inconsistent, and imprecise. This site needs JavaScript to work properly. Maternal mid-pregnancy autoantibodies to fetal brain protein: the early markers for autism study. Science. They did find significantly higher levels of lead in the hair of patients with ASD than those of controls. The lack of association was consistent in pooled analysis of the adjusted estimates, studies of anti-RhD antibody treatment, and studies of direct thimerosal exposure. J Child Psychol Psychiatry. The association between maternal antidepressant use during pregnancy and ASD is more controversial. Novel uses to study complex traits and genetic diseases. 2013;103 Suppl 1:S46–55. Wang et al. Hum Reprod Update. Levels of two diet-related factors that also can be affected via pharmacological (supplements) or physical routes (sunlight) have taken on new importance in the search for the environment-autism connection. Eur J Neurosci. 2 > 50% or P value of heterogeneity test < 0.10), magnitude of association (relative risk estimate <2.0 small, 2.0–5.0 medium, >5.0 large), publication bias, and indirectness (that is measuring exposure based on population-level assessment) [21, 22]. Kinney DK, et al. Epigenetic transmission of the impact of early stress across generations. Baxter AJ, et al. Immaturity of autoregulatory mechanisms and white matter susceptibility in the neonate are important contributory factors in hypoxic-ischemic brain damage [85]. The reviews on nutritional elements have yielded limited useful and/or inconclusive information about the beneficial effects of folic acid and omega-3, while vitamin D deficiency seems to be common in children with ASD. Not only the prevalence of ASD seems to be higher in boys but also the psychopathological, biochemical, and genetic aspects of ASD also appear to be different between males and females [89, 90]. J Child Neurol. These epiphenomena are observed with higher frequency in children with ASD but are not necessarily causal [55]. Influence of prenatal exposure to environmental pollutants on human cord blood levels of glutamate. The authors found no evidence for a higher risk of ASD in subjects who are vaccinated. In subgroup analysis, family history of autoimmune thyroid disease, diabetes, psoriasis, and rheumatoid arthritis were associated with an average 49–64% increase in risk of ASD in the offspring (Table 1).

Association between several persistent organic pollutants and thyroid hormone levels in cord blood serum and bloodspot of the newborn infants of Korea. In a systematic review of the association between maternal immigration and risk of ASD, Crafa and Varfa [53] found ten eligible studies. Oxidative stress-related biomarkers in autism: systematic review and meta-analyses. Xu and colleagues conducted a meta-analysis on the association between maternal diabetes and ASD in the offspring. International Journal of Epidemiology, 43(2), 443-464 "Environmental chemical exposures are increasingly understood to be important in causing autism, with current theories positing that autism is caused by the interplay of multiple genetic and environmental contributions that differ from individual to individual. Environ Health Perspect. Newer studies of monozygotic twins have yielded concordance rates of <50%, with lower concordance for dizygotic twins, suggesting that both genes and environment play roles in the development of ASD [4, 14–16]. Schizophr Res. Background: According to recent evidence, up to 40-50% of variance in autism spectrum disorder (ASD) liability might be determined by environmental factors. Maternal smoking and autism spectrum disorder: a meta-analysis. PubMed Google Scholar. J Autism Dev Disord. Environmental, genetic, and epigenetic factors all play a role in determining the risk of autism and some of these effects appear to be transgenerational. Another meta-analysis of 12 studies by Babaknejad et al. Genetic heritability and shared environmental factors among twin pairs with autism. Am J Obstet Gynecol. The epidemiology and global burden of autism spectrum disorders. Google Scholar. Vaccine. Neuroglial activation and neuroinflammation in the brain of patients with autism. PubMed  The reviews on nutritional elements have been inconclusive about the detrimental effects of deficiency in folic acid and omega 3, but vitamin D seems to be deficient in patients with ASD. Importantly, the authors observed an overexpression of FMRP between 36 and 39 weeks of pregnancy in the normal brain, which suggested an important physiological role for FMRP in synaptic plasticity during this period. While genetics is now a well-established risk factor, several data support a contribution of the environment as well. Google Scholar. In a meta-analysis, Lam and colleagues [46] found a small but significant and precise association between prenatal exposure to particulate matters and risk of ASD. Mol Psychiatry. Molecular neurobiology of lead (Pb(2+)): effects on synaptic function. The effect size was small and inconsistent but precise. Importantly, a recent Cochrane systematic review found no evidence for the beneficial effect of chelation therapy on ASD [50] (Table 2).

[41] showed significantly lower zinc levels in children with ASD. Moreover, gene-environment interaction and epigenetics of ASD are two areas that are clearly understudied but, as recent evidence shows, could potentially provide a substantial insight into the etiology of ASD. However, the findings were inconsistent and were limited by the self-report in the majority of studies (Table 2). They found statistically significant pooled estimates with small effect size for abnormal presentation, breech presentation, cord complications, fetal distress, multiple births, low birth weight, small for gestational age, congenital malformations, hyperbilirubinemia, and earlier birth (first vs. third born). Neurotherapeutics. AM was responsible for the data collection and abstraction and quality assessment. Evidence suggested a medium yet imprecise effect size for five risk factors including maternal hemorrhage, Rh or ABO incompatibility, birth injury or trauma, birth weight <1500 g, and feeding difficulties at birth. Autism spectrum disorders, endocrine disrupting compounds, and heavy metals in amniotic fluid: a case-control study. Int J Epidemiol. 1997;36(2):272–81. Article  Baron-Cohen S, Knickmeyer RC, Belmonte MK. In a meta-analysis of five studies, Gardener et al. Deth et al. We extracted the following for meta-analyses: number of studies, study design, imprecision (>0.25 difference between effect estimates and their upper or lower confidence bound for dichotomous variables and >0.5 difference for continuous outcomes), inconsistency (presence of heterogeneity I Van Wijngaarden-Cremers PJ, et al. Advanced parental age and autism risk in children: a systematic review and meta-analysis. [24, 25] carried out two comprehensive reviews of prenatal and perinatal risk factors for ASD. 2013;36:67–81. Pediatrics. Another systematic review suggested that folate deficiency might interact with certain polymorphism in the methylene tetrahydrofolate reductase (MTHFR) gene to increase risk of ASD [45]. 2015;10(6):e0129906. 2015;42(10):2742–60. 2019 Jan 9;10:1. doi: 10.1186/s13229-018-0253-1. Kim YS, Leventhal BL. Autism spectrum disorders and autistic traits: a decade of new twin studies. Current evidence suggests that several environmental factors including vaccination, maternal smoking, thimerosal exposure, and most likely assisted reproductive technologies are unrelated to risk of ASD. GRADE: an emerging consensus on rating quality of evidence and strength of recommendations. 2006;9(4):350–8. Given that ASD has a high comorbidity rate with depression, such associations might reflect a shared risk mechanism rather than causality [56]. 2016;21(4):Np110–26. Factors to Reduce Risk. Genetic variance for autism screening items in an unselected sample of toddler-age twins. Halladay AK, et al. 2011;68(11):1095–102. J Autism Dev Disord. Folate deficiency in a background of methylene tetrahydrofolate reductase (MTHFR) gene polymorphism might impair methyl donation and subsequently lead to impaired epigenetic regulation [64]. De Palma and colleagues [48] performed a meta-analysis of studies that compared hair concentration of heavy metals between patients with ASD and controls. 2013;136(Pt 9):2799–815. The authors further identified seven studies that reported an association between heavy metal concentration (mostly mercury and lead) and severity of ASD. Evidence of the gluten-free and casein-free diet in autism spectrum disorders: a systematic review. Iran J Child Neurol. [39] found precise (but inconsistent) evidence that there was no association between maternal smoking and risk of ASD in the offspring. Ronald A, Hoekstra RA. Neurochemistry in the pathophysiology of autism. It has been suggested that some environmental factors such as certain toxins and vitamin D deficiency increase the risk of gene mutation that in turn can lead to an increased risk of ASD [58]. Kim S, et al. Arq Neuropsiquiatr. As we mentioned earlier, evidence suggests a role for birth asphyxia-hypoxia in risk for ASD. The teratology of autism. Article  2013;59:442–8. Six out of ten studies found that giving birth postmaternal migration significantly increased the risk of ASD, with the exception of children born to Hispanic migrant mothers who had lower rates of ASD (Tables 1 and 2). California Privacy Statement, Mitchell MM, et al. Although reviewing systematic reviews and meta-analyses inherently focuses on the most well-studied findings, it automatically excludes the studies that are published after the included reviews or that, for any reason, are not systematically reviewed. [51] found that three out of five studies of phthalate exposure showed a significant association between phthalate exposure and risk of ASD (Table 2). Systematic review of five metals (mercury, lead, cadmium, aluminum, and arsenic) contained eight or more case-control studies. In the present paper, we conducted a review of systematic reviews and meta-analyses of environmental risk factors for ASD. Of these, 584 records were excluded by title or abstract. Over the past 15 years or so, scientists have investigated many of these factors to determine how they may contribute to autism. Paradoxical Effects of a Cytokine and an Anticonvulsant Strengthen the Epigenetic/Enzymatic Avenue for Autism Research. Studies that use genetically informed approach (e.g., family-based studies and in vitro fertilization designs) offer a new way to address the challenge of gene-environment correlation [111]. 2013;10(4):742–56.

Studies of the association between endocrine-disrupting chemicals and ASD are scarce. Cases and controls were born between 2005 and 2009. There is evidence which clearly shows that the time before, during and close to birth are a critical period in the development. J Intellect Disabil Res. Methods: Risk factors were extracted from the birth certificates of singleton cases (n=198) and controls (n=4,801) from the Case-Control Study of Personal and Environmental Risk Factors for Childhood Autism in Southwestern Pennsylvania.

Dingemans MM, van den Berg M, Westerink RH. Goines PE, Ashwood P. Cytokine dysregulation in autism spectrum disorders (ASD): possible role of the environment. This maladaptive response is shaped by interplay between a multitude of risk and protective factors at various levels and evolves as the result of a dynamic interaction between a person and their environment across the lifespan [110]. But there’s still little definitive information. PubMed  According to recent evidence, up to 40–50% of variance in autism spectrum disorder (ASD) liability might be determined by environmental factors. EMB theory of ASD builds on an empathizing-systematizing theory of psychological sex differences and suggests that ASD might reflect an extreme male pattern (i.e., more systematizing, less empathizing) [92]. In a systematic review, Rossignol et al. Thyroid hormones are associated with exposure to persistent organic pollutants in aging residents of upper Hudson River communities. 2017 Oct 3;79(Pt B):340-368. doi: 10.1016/j.pnpbp.2017.07.011. Rosenberg RE, et al. 2014;9(2), e88661. James S, et al. 2013: American Psychiatric Pub. Bloom MS, et al. Environmental risk factors for autism include being born prematurely, soon after an older sibling or to a mother with diabetes, for example. Many environmental pollutants have been associated with altered glutamate levels in umbilical cord blood [105]. AM, EV, and AR drafted the manuscript. However, the included studies were generally of high quality. 2005;310(5749):819–23.
