[Research progress on the association between prenatal nutritional factors and autism spectrum disorder].

This review looks at how a mother's diet during pregnancy might affect the risk of autism in children. Some nutrients like multivitamins, vitamin D, healthy fats, and iron may help reduce autism risk. However, different studies show mixed results, so more research is needed to be certain about these connections.

This Chinese review examines the relationship between maternal nutrition during pregnancy and autism spectrum disorder (ASD) risk. The review suggests that certain prenatal nutritional factors may influence ASD development, with multivitamin supplementation and adequate vitamin D intake potentially reducing risk. Polyunsaturated fatty acids (PUFA) and iron consumption also show similar protective associations. However, the authors acknowledge that research findings remain inconsistent across studies.

The review aims to synthesize current knowledge on key nutrients that may affect ASD risk during pregnancy, providing a foundation for developing targeted perinatal nutritional intervention strategies.

Findings support the importance of comprehensive prenatal nutrition counseling. Healthcare providers should consider discussing multivitamin supplementation, vitamin D status, and adequate PUFA and iron intake with pregnant women, while noting the preliminary nature of current evidence.

Research findings are inconsistent across studies. As a narrative review, specific study quality and methodology details are not provided. Sample sizes and effect sizes are not reported.

Autism spectrum disorder (ASD) is a neurodevelopmental condition originating in early life, presenting significant challenges for affected families and society. ASD is characterized by atypical brain development occurring throughout gestation. Maternal diet during pregnancy plays a crucial role in ASD pathogenesis. Specifically, prenatal multivitamin supplementation and adequate vitamin D intake may reduce ASD risk; similar protective effects have been associated with polyunsaturated fatty acid (PUFA) and iron consumption.

Although research findings are inconsistent, prenatal nutritional interventions represent a promising strategy for mitigating the future risk of mental health and other disorders in offspring. Therefore, this article reviews key nutrients implicated in ASD risk during pregnancy, to provide a theoretical foundation for developing precise perinatal nutritional intervention plans.
