Children of the 90s has recently started enrolling the grandparents of the original children who were born in 1991 and 1992, and we would like to enrol up to 1000 grandparents into the study in their own right.
Having information on three generations of the same family will be an incredibly important resource for scientists around the world. It will help us to examine the importance of lifestyle and genetics on health, and how this is passed through the generations.
If you are a Children of the 90s grandparent, this is a great opportunity for you to take an active role in one of the world's most important long-term health research projects. By taking part you will be helping us carry out even more research that will potentially lead to benefits in public health.
All grandparents of the original Children of the 90s children are equally important to us – whether biological or not.
Please read on to find out more:

Our discoveries: autism and grandmothers
We’ve discovered that the mothers of children with an autistic spectrum disorder (ASD) are more likely to have had older mothers themselves. Women who were 30 or more when they gave birth are about 50% more likely to have a child with an ASD compared with younger mothers. And grandmothers who were 30 or more when they gave birth to their daughters are nearly twice as likely to have a grandchild with an ASD. This rises to three times as likely in grandmothers who were over 35 when they gave birth.
Professor Jean Golding, who did the research, said: "No other study, to my knowledge, has considered the grandparents’ ages in relation to autism."
Professor Marcus Pembrey, who worked with Jean on this research, added: "This discovery points to factors operating at the time when the mother was in the womb which may influence her developing ovaries and thus the genomes of her future children."
Calling all grandparents!
