Brief summary

The aims of the Kidskin Follow up Study is to; - Determine if there is a difference in the prevalence of myopia between children in the Kidskin intervention and control schools and whether an individual's of sun protection during childhood is associated with myopia. - Determine if myopia is associated with other markers of outdoor activity, conjunctival UV auto-fluorescence (CUVAF), pterygium, melanocytic naevi counts and trajectory dorsal hand skin wrinkling and vitamin D levels. - Determine which aspects of myopia-related ocular biometry are associated with the protective effect of outdoor activity. - Investigate gene-environment interactions of myopia-risk gene-markers with sun-exposure measures.

Interventions

We aimed to assess myopia or short-sightedness rates in young adult participants, who were part of the Western Australian Kidskin Study while they were in primary school in the 1990s. The Kidskin study intervention resulted in a reduction in time spent outdoors and an increase in the use of sun protection while outdoors. We wish to now investigate the possible impact that this intervention has had on the development of myopia in these participants who are now young adults. To gather the data

We aimed to assess myopia or short-sightedness rates in young adult participants, who were part of the Western Australian Kidskin Study while they were in primary school in the 1990s. The Kidskin study intervention resulted in a reduction in time spent outdoors and an increase in the use of sun protection while outdoors. We wish to now investigate the possible impact that this intervention has had on the development of myopia in these participants who are now young adults. To gather the data we repeated during one follow-up visit, some of the questions and measures that were performed in the original Kidskin Study (1995-2001). This includes completing a questionnaire, undertaking a comprehensive eye examination, have naevi counts, and we will also ask to provide a blood sample. In addition to this, participants underwent a comprehensive eye examination. Schools in the intervention groups received a multicomponent intervention. Both the moderate and high intervention groups were taught a specially designed sun protection curriculum.
