My research interests focus on the influence of health and health behaviours before and during pregnancy on the development of the offspring. I run a large cohort study, the Southampton Women’s Survey (SWS), which recruited women when not pregnant and we are following up their children (now aged 12 to 20 years). We have developed various intervention studies based at least in part on SWS findings, with the aim of improving preconception and pregnancy health behaviours, body composition and health in parents. A particular interest is in adolescent health as teenagers will become parents of the next generation.
