| The study found pregnant women with low vitamin D levels at 20 weeks’ gestation were more likely to have a child with autistic traits by the age of six. | The study found pregnant women with low vitamin D levels at 20 weeks’ gestation were more likely to have a child with autistic traits by the age of six. |
| The finding has led to calls for the widespread use of vitamin D supplements during pregnancy, just as taking folate has reduced the incidence of spina bifida in the community. | The finding has led to calls for the widespread use of vitamin D supplements during pregnancy, just as taking folate has reduced the incidence of spina bifida in the community. |
| “This study provides further evidence that low vitamin D is associated with neurodevelopmental disorders,” said Professor John McGrath from the University of Queensland’s Brain Institute, who led the research alongside Dr Henning Tiemeier from the Erasmus Medical Centre in the Netherlands. | “This study provides further evidence that low vitamin D is associated with neurodevelopmental disorders,” said Professor John McGrath from the University of Queensland’s Brain Institute, who led the research alongside Dr Henning Tiemeier from the Erasmus Medical Centre in the Netherlands. |
| McGrath said supplements might reduce the incidence of autism, a lifelong developmental condition that affects, among other things, how an individual relates to their environment and other people. | McGrath said supplements might reduce the incidence of autism, a lifelong developmental condition that affects, among other things, how an individual relates to their environment and other people. |
| “We would not recommend more sun exposure, because of the increased risk of skin cancer in countries like Australia,” he said. “Instead, it’s feasible that a safe, inexpensive, and publicly accessible vitamin D supplement in at-risk groups may reduce the prevalence of this risk factor.” | “We would not recommend more sun exposure, because of the increased risk of skin cancer in countries like Australia,” he said. “Instead, it’s feasible that a safe, inexpensive, and publicly accessible vitamin D supplement in at-risk groups may reduce the prevalence of this risk factor.” |

| While it’s widely known vitamin D is vital for maintaining healthy bones, there’s also a solid body of evidence linking it to brain growth. | While it’s widely known vitamin D is vital for maintaining healthy bones, there’s also a solid body of evidence linking it to brain growth. |
| The study examined approximately 4,200 blood samples from pregnant women and their children, who were closely monitored as part of the long-term “Generation R” study in Rotterdam, the Netherlands. | The study examined approximately 4,200 blood samples from pregnant women and their children, who were closely monitored as part of the long-term “Generation R” study in Rotterdam, the Netherlands. |

| “There are likely dozens, if not hundreds, of different mechanisms that can lead to autism. Now this study gives us an inkling of one possible mechanism but before we think about anything we need to see a replication of this finding.” | “There are likely dozens, if not hundreds, of different mechanisms that can lead to autism.
