Mothers are key to the success of Children of the 90s. 14,500 women living in the greater Bristol area agreed to take part in the project when they were pregnant in 1991 or 1992. Since then they have attended numerous Focus visits, donated biological samples including their placenta and DNA, and answered thousands of questions about themselves and their children.
If you’re a Children of the 90s mother, you may have been involved in Focus on Mothers which ran from 2009 to 2015. Thanks to the 5,000 women who took part, we have gathered an enormous amount of information about women’s physical, mental and emotional health and wellbeing during the menopause years, which is often a time of great change. We’ll soon be able to share the results of this research with you, so watch this space!
Meet Michelle, the first Children of the 90s mother
"When my study child was born I already had a 20-month-old daughter and I was keen to make sure that the girls were brought up to be as healthy as possible. I thought that Children of the 90s was a very important study and I was keen to take part in it. Now, 24 years later and a grandmother I still do!"
Key discovery: vitamin D and bone health
Women are given a lot of advice during pregnancy, including to take a vitamin D supplement to keep bones and teeth healthy. So, we looked at mothers’ vitamin D levels three times during pregnancy and compared it with their child’s bone health when he or she was aged nine. In the largest study of its kind in the world, involving more than 4,000 pairs of mothers and children, we found no evidence that low vitamin D levels in the mothers affected their child’s bone health.
Professor Debbie Lawlor who did the research said: "We believe that there is no strong evidence that pregnant women should receive vitamin D supplementation to prevent low bone mineral content in their children, although we cannot comment on other possible effects of vitamin D in pregnant women."
