Overview of the current data resources available in the SIG area

Hearing

The Senses SIG has access to parent report of ear and hearing problems at age 3 and 6 years, middle ear function (tympanometry) and hearing thresholds at age 6 years. This has enabled the Senses SIG to create various diagnostic criteria for otitis media at 3 and 6 years of age, and hearing loss at 6 years of age.

Vision

The cohort had no ocular examination until the 20-year follow-up. However, at ages 3 and 5 years, a study nurse screened participants’ eyes and recorded if they had a gross anomaly. At the 20-year follow-up, each participant had 3-hours long eye examination which included fundus photography, corneal topography, conjunctival UV autofluorescence (CUVAF) photography, measurement ocular biometry and several other tests.  Additionally, they completed a questionnaire on their previous ocular history, sun exposure behaviours and family history of eye diseases. At the 22-year follow-up, abridged version of these questions was repeated.

Overview of current/recent SIG activity

Hearing

There is a core dataset for ear and hearing outcomes for Raine Study participants at 3 and 6 years of age and are conducting a survey of listening habits for Raine Study participants in the 26-year follow-up. Currently the Senses SIG is leading a series of studies to examine the longer term developmental effects of otitis media and hearing loss on developmental outcomes (including language, behavioural and cognitive development) at 5, 8, 12 and 16 years of age.

Vision

A short eye examination is now completed on all parents who has attended to the Raine Study Parent Sleep Study.  Currently, the Raine Study participants are undergoing the same eye exam at the 26-year follow-up to determine any changes in their vision and eye measures compared to results at the 20-year follow-up. The Vision team of Senses SIG continues to analyse data from 20 and 22 years of age and gather evidence on genetic and environmental risk factors associated with development and progression of many eye diseases including myopia, pterygium, strabismus, keratoconus and glaucoma.

Outline of SIG plans for next 5 years

Hearing
  • Complete and publish analyses of otitis media and hearing loss on long-term developmental outcomes
  • Complete data collection from the hearing and listening habits survey for the 26-year follow-up
Vision
  • To identify genes specifically associated with measures of progression of diagnosed myopia and with development of myopia in young adulthood
  • To determine the association of detailed measures of education – including educational attainment, scores and gap year activities – with progression of childhood myopia and development of myopia in young adulthood
  • To determine whether there is any association between longer duration and intensity of use of personal electronic devices and risk of later-onset myopia, or childhood myopia progression.
  • To determine gene-environment interactions that are important to the progression of childhood myopia and the onset of young adult myopia and to identify the molecular pathways that these genes involve.

Brief list of potential student/early career researcher projects

Hearing
  • Influence of otitis media on later cognitive development in children

Top 5-10 key findings (with reference)

Hearing
  • This study showed that 26.8% of children suffered recurrent otitis media and was the first study to provide prevalence data for this disease in a general Australian paediatric population.   Brennan-Jones, C.G., Whitehouse, A.J.O., Park, J., Hegarty, M., Eikelboom, R.H., Swanepoel, D., White, J.D., Jamieson, S.E. Prevalence and risk factors of parent-reported recurrent otitis media during early childhood in the Western Australian Pregnancy Cohort (Raine) Study. Journal of Paediatrics and Child Health, 51(4): 403-9, 2015.
  • This study showed that predominant breastfeeding for >6 months is protective against otitis media in children at three years of age but that the protective effect does not extend to children at six years of age, where other social and environmental factors may be stronger predictors of otitis media.   Brennan-Jones, C.G., Eikelboom, R.H., Jacques, A., Swanepoel, D., Atlas, M.D., Whitehouse, A.J.O., Jamieson, S.E., Oddy, W.H. Predominant breastfeeding for the first six months of life is protective against middle ear effusion in early childhood: a prospective birth cohort study. Clinical Otolaryngology, Mar 31, 2016.
Vision
  • Analysis of genetic profiles from DNA collected in blood samples and data from comprehensive eye assessments in over 45,000 individuals (including Raine participants) identified 24 new gene variants associated with refractive error. (Verhoeven, Virginie J M, Pirro G Hysi, Robert Wojciechowski, Qiao Fan, Jeremy A Guggenheim, René Höhn, Stuart MacGregor, et al. 2013. “Genome-Wide Meta-Analyses of Multiancestry Cohorts Identify Multiple New Susceptibility Loci for Refractive Error and Myopia.” Nature Genetics 45 (3) (March): 314–8. doi:10.1038/ng.2554)
  • Eye length is a major determinant of refractive error and thus of myopia. We identified eight markers for eye length and confirmed one previously reported markers. Of the nine genetic markers, five were associated with refractive error in 18 independent cohorts. This study provided the evidence of shared genes between eye length and refractive error, but importantly also suggested that these traits may have unique pathways. (Cheng, C.Y., Schache, M., Ikram, M.K., et al.,(2013). Nine loci for ocular axial length identified through genome-wide association studies, including shared loci with refractive error. American Journal of Human Genetics, 93(2):264-77)
  • Vitamin D levels in blood samples and eye examination data from Raine participants at 20 years of age found that young adults with myopia had lower vitamin D levels. Vitamin D deficiency was also associated with a higher risk of myopia (Yazar, S., Hewitt, A. W., Black, L. J., McKnight, C. M., Mountain, J. A., Sherwin, J. C., … Mackey, D. A. (2014). Myopia is associated with lower vitamin D status in young adults. Investigative Ophthalmology & Visual Science, 55(7), 4552–9. doi:10.1167/iovs.14-14589.)
  • Every 2 years of additional education increases the myopia levels by one diopter thus indicating a causal relationship between myopia and education. (Cuellar-Partida, G., Lu, Y., Kho, P.F., et al., (2016). Assessing the Genetic Predisposition of Education on Myopia: A Mendelian Randomization Study. Genetic Epidemiology, 40(1):66-72.)
  • Conjunctival UV autofluoresence (CUVAF) is a quantifiable measure of ocular sun exposure. In the Raine Study, myopia was inversely associated with CUVAF levels further supporting the relationship between myopia and time outdoors (McKnight, C. M., Sherwin, J. C., Yazar, S., Forward, H., Tan, A. X., Hewitt, A. W., Pennell, C. E., et al. (2014). Myopia in young adults is inversely related to an objective marker of ocular sun exposure: The Western Australian Raine Cohort Study. American Journal of Ophthalmology, 158(5), 1079–1085.e2.). However, the following characteristics must be considered when used: [1] prevalence of CUVAF increases with increasing latitude (toward equator); [2] although it is largely environmental, genes also play a significant role in its development (Yazar, S., Cuellar-Partida, G., McKnight C.M., Quach-Thanissorn, P., Mountain, J.A., Coroneo, M.T., et al. (2015) Genetic and Environmental Factors in Conjunctival UV autofluorescence. JAMA Ophthalmology, 133(4): 406-12.)
