Between April 1998 and October 2002 we interviewed some 12,583 women – an amazing level of support from the women of Southampton. Of those, 3,158 have gone on to have babies in the study – nearly all of whom were measured at birth. The following number of home visits to see the mums and children have been undertaken by our research nurses:-

2,963 – 6 month visits
2,877 – 1 year visits
2,779 – 2 year visits
2,644 – 3 year visits
1,076 – 4 year visits
2,027 – 6-7 year visits
1,055 – 8-9 year visits
1148 – 11-13 year visits

The 4 year visits have resulted in the following data:

900 – DXA (bone scans)
593 – Actiheart physical activity measures (mother and child)

1,399 – 6-7 year clinic visits

At 8-9 years, we have the following:

1,055 clinic visits
973 DXA bone scans
353 MRI heart scans

At 11-13 years, we have the following:

1,148 clinic visits
1,133 DXA bone scans
1,112 brain development assessments in child
