In many countries the incidence of melanoma has been doubling in every 10 years. Since 1930, the rate of melanoma has increased over 1,800% and researchers are expecting this trend to continue and increase for the next 10 to 20 years. Primary prevention and early detection of skin cancer in childhood is important to reduce the risk of developing skin cancer later in life. Primary prevention programmes are more beneficial and effective in children, not only due to the particular importance of sunlight exposure during this period, but because this is when individuals are more open to changes and adopt new attitudes and behaviour. The purpose of this manuscript is to review the results of intervention studies designed to modify sun exposure behaviour among children in the United States of America, Australia and Europe. An additional purpose is to summarize the recommendations obtained from the reviewed studies. The strongest recommendation to emerge from this review is that the skin cancer primary prevention programme should be carried out over several school years, not just one time, to produce changes in the sun safety behaviour. Moreover, it recommends that parents should be targeted to educate their children about sun protective skills and promote skin cancer prevention behaviour.
