ABSTRACT
OBJECTIVE: To evaluate the factors associated with sunburns and with sun protection practice in Hungarian primary school children. METHOD: We investigated children's (the median age: 8, range 5 to 12 years) and parents' assessment of sun sensitivity and sun protection characteristics in cities Gyor and Zalaegerszeg (Hungary) in 2004. This cross-sectional study was part of a programme intended to increase children's and parents' awareness of harmful effects of excessive sunbathing. Analyses were based on 1804 multiple choice questionnaires. RESULTS: At multivariate analysis a significant association between sunburns and fairness of complexion, freckles, use of sunscreens and T-shirts, and higher school-class level was observed. Sunburn was inversely associated with hat-wearing. Parents were more likely to apply sunscreen to children with light eyes and to the younger ones, to protect fair skinned children with T-shirts; to protect males and children with fair skin and light eyes with hats. CONCLUSION: Since environmental factors play an important role in the development of skin cancer, morbidity could be reduced by primary prevention. Sun protection habits should therefore be taught early in life, and parents' behaviour adapted. Phenotype is not only related to sunburns but it also appears to influence parents' sun safety behaviour.

For many years the molecular biology has been one of the most promising fields of science and its several methods have been used in practice. These new methods of molecular biology made impression on epidemiology and developed a new discipline, called molecular epidemiology. The molecular and predictive epidemiology play more and more important roles in the prevention of cancers. Early biomarkers could identify the high risk population to have the possibilities of primary preventive interventions. It uses both molecular biological methods and the elements of epidemiology. Its specificity is not high enough to establish the diagnosis but it can be used to follow the "minimal residual disease" and with markers of individual susceptibility, to assess the risk of tumors. As to the practice there are many problems because of the limited therapeutic possibilities, but the molecular and predictive epidemiology becomes an important part of medicine in the future.
