Improvement of sun-related knowledge and protection practice.

The aim of this study was to examine changes in sun-related knowledge and sun protection practice among Greek mothers and children during 1993-2002. A total of 315 mothers in 1993 and 295 mothers in 2002, with their 649 and 491 children respectively, were randomly selected to answer the same questionnaire on sun-related issues. Sun knowledge and protection practice were determined by an index score. Significantly more mothers in 2002 compared to 1993 had 'good' (58.9% versus 16%) and 'excellent' levels (28% versus 6%) of sun knowledge (p<0.001). In 2002, 40% of the mothers and children (versus 27% and 30% each in 1993) had 'good' levels of sun protection practice, while 28% of the mothers and 26% of the children (versus none in 1993) reported 'excellent' levels (p<0.001). Knowledge and sun protection practice were significantly improved, probably due to an information campaign conducted between both surveys.
