MS more prevalent in people born in spring

04 January 2010

Newly published research from Scotland suggests that babies born in spring face an increased risk of developing multiple sclerosis later in life.

The researchers looked at records of 1,300 people with MS born in the west of Scotland between 1922 and 1992. A much higher than expected proportion was born in March, April or May. In contrast, a lower proportion of those born in the autumn, particularly in November went on to develop MS.

The study, published in European Neurology, reflects earlier studies that have drawn a connection with vitamin D levels in the mother. A principal source of vitamin D is regular exposure to sunlight. For children born in April, the last stages of the pregnancy will have coincided with the darkest months of the year.

Pam Macfarlane, Chief Executive of the MS Trust said, "This study adds to the evidence that suggests that vitamin D may have a role in the development of MS. Further research will make the implications of this work more apparent."
