Overview of current/recent SIG activity

Currently a range of different projects are working with Raine Study dietary data; these involve other Raine Study SIGs, national collaborators, and international collaborators in the US, UK and Europe.  Considerable work is being undertaken using Raine Study dietary data, to better understand the relationships between dietary intake and the early development of chronic diseases, including cardiovascular disease, type 2 diabetes, obesity, bone disorders, and mental health disorders.  Projects are also examining the social and environmental determinants of dietary intake, to inform interventions for improving population dietary intakes. The longitudinal dietary data collected in the Raine Study makes it an ideal cohort to study these factors, and the Diet SIG welcomes new research proposals and collaborations.

Outline of SIG plans for next 5 years

  • Continue making high quality dietary assessments at each core follow up with increased use of digital technologies.
  • Increase the inclusion of early-career and mid-career researchers as CIs on grants relevant to Raine Study nutrition data, for capacity building and succession planning.
  • Undertake high quality dietary assessments in 1st and 3rd generations in the Raine Study.
  • Establish new collaborations with other Raine Study SIGs e.g. Respiratory, Immunology & Inflammation, Genetics, Biostatistics; and strengthen existing collaborations e.g. Cardiometabolic, Built & Social Environment, Psychological, Bio, Musculoskeletal
  • Increase international and national collaborations with the Diet SIG by attracting overseas and interstate postdocs, PhDs and other investigators

Brief list of potential student/early career researcher projects

  • Are dietary patterns associated with biomarkers of inflammation and vascular function? (Ambrosini)

Top 5-10 key findings (with reference)

Nutrition work in the Raine Study began with Prof Oddy’s PhD looking at early risk factors for childhood asthma.  She found a significant reduction in the risk of childhood asthma at six years if exclusive breast feeding is continued for at least the four months after birth.1 These findings are important for our understanding of the cause of childhood asthma and suggest that public health interventions to optimise breast feeding may help to reduce the community burden of childhood asthma and its associated traits. Raine data also indicated that a longer duration of breastfeeding may reduce the prevalence and subsequent morbidity of respiratory illness and infection in infancy.2
