Methods A case-control study was conducted through a questionnaire with 108 ASD cases, 79 ID cases, and 108 controls. The ASD and ID cases were students from special educational schools in Tianjin from 2012 to 2014. The age- and sex-matched controls were from a high school, three primary schools, and a kindergarten in Tianjin. Multivariate logistic regression was performed. Results Paternal habit of eating hairtail before fertilization, maternal preference for fruits during pregnancy, and maternal habit of eating grass carp during pregnancy were preventive factors for ASD. Paternal habit of drinking alcohol before fertilization was a risk factor for ID, whereas maternal preference for fruits during pregnancy and maternal habit of eating crucian carp during pregnancy were protective factors for ID. Conclusion Parental fish consumption is beneficial for the prevention of ASD and ID. Meanwhile, the protective effects of fish consumption on ASD and ID differ. More attention should be paid to the combined effect of other food when eating fish.展开更多
