Observable essential fatty acid deficiency markers and autism spectrum disorder
Insights
Early breastfeeding, specifically intake of colostrum within the first hour, may reduce the risk of Autism Spectrum Disorder (ASD). Infants with essential fatty acid (EFA) deficiency signs and not breastfed were more likely to be diagnosed with ASD.
Area of Science:
- Neurodevelopmental Disorders
- Nutritional Neuroscience
- Pediatric Health
Background:
- Autism Spectrum Disorder (ASD) is linked to essential fatty acid (EFA) deficiencies.
- Dysregulation in phospholipid metabolism is hypothesized as a biological basis for ASD.
- Early life nutrition and fatty acid metabolism are critical for neurodevelopment.
Purpose of the Study:
- To compare the fatty acid status in children with ASD and their typically developing siblings.
- To investigate the association between infant feeding practices, particularly colostrum intake, and ASD diagnosis.
- To explore potential risk factors for ASD related to early nutrition and fatty acid metabolism.
Main Methods:
- Pilot study comparing 19 children with ASD to 23 typically developing siblings.
- Assessment of observable signs of essential fatty acid (EFA) status.
- Collection of parental reports on pregnancy, birth, breastfeeding history, and infant colostrum intake.
Main Results:
- Infants not breastfed (with colostrum) within the first hour, and with a history of EFA deficiency symptoms, were more likely to have an ASD diagnosis when analyzed within their family group.
- No significant association was found between ASD diagnosis and formula use, breastfeeding duration, gestational age, or Apgar scores.
- Results suggest a potential link between early infant feeding practices, fatty acid metabolism, and ASD risk.
Conclusions:
- Early infant feeding, including immediate post-partum colostrum intake, may play a role in the risk of developing Autism Spectrum Disorder (ASD).
- Findings support previous research highlighting the importance of fatty acid metabolism and breastfeeding in relation to ASD.
- Further research into early nutritional interventions and their impact on neurodevelopmental outcomes is warranted.
Abstract:
Autism Spectrum Disorder (ASD) has been associated with essential fatty acid (EFA) deficiencies, with some researchers theorising that dysregulation of phospholipid metabolism may form part of the biological basis for ASD. This pilot study compared observable signs of fatty acid status of 19 children with an ASD diagnosis to 23 of their typically developing siblings. A pregnancy, birth and breastfeeding history was also obtained from their parents, which included a measure of infant intake of fatty acid rich colostrum immediately post-partum. When considered within their family group, those infants not breastfed (with colostrum) within the first hour of life and who had a history of fatty acid deficiency symptoms were more likely to have an ASD diagnosis. Other variables such as formula use, duration of breastfeeding, gestational age and Apgar scores were not associated with group membership. The results of this study are consistent with previous research showing a relationship between fatty acid metabolism, breastfeeding and ASD such that early infant feeding practices and the influence this has on the fatty acid metabolism of the child may be a risk factor for ASD.

These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
