NameDr Sarah Crozier
Sarah Crozier is a senior medical statistician who has worked extensively on the Southampton Women’s Survey, an internationally-renown cohort study which recruited 12,583 young non-pregnant women living in the city of Southampton. Of these women, 3,158 went on to become pregnant and deliver a live-born singleton infant and the detailed follow-up of the offspring is continuing. The study design (unique in the Western world) allows detailed research into pre-pregnancy and pregnancy influences on offspring health.
Sarah’s research using the Southampton Women’s Survey has focused on women’s health behaviours. She is particularly interested in the application of statistical techniques to describe diet, and has used Principal Component Analysis to develop dietary patterns scores that characterise broad features of women’s, infants’ and children’s diets. The prudent diet score has been a particularly useful means of characterising one of the most important aspects of women’s dietary choices. Sarah has developed a 20-item food frequency questionnaire which enables prudent diet scores to be estimated amongst young women in Southampton.
A further aspect of Sarah’s research has been the investigation of predictors of childhood adiposity. In particular, she has found that low levels of maternal vitamin D and excessive pregnancy weight gain are associated with greater adiposity at age 6.
Sarah is also involved in research into the use of statistical techniques to model growth. She is interested in the application of a variety of techniques to answer clinical questions by using the extensive resource of anthropometric data in the Southampton Women’s Survey cohort.
