Abstract
Background: Internet has been increasingly studied as a resource to identify patterns of searches useful to public policies for health promotion. Our hypothesis is that perceived overexposure to sun during Brazilian summer could raise attention towards web-based information on ultraviolet protection and self skin examination (SSE) – the “summer effectâ€. Our objective is to identify patterns of searches on skin cancer prevention along a 48 months observation.
Methodology: We employed log files tracking to analyze search patterns in the most visited institutional website on cancer (Brazilian National Cancer Institute /INCA) which provides contents of qualified information concerning prevention, diagnosis and treatment. We used a log analyzer software to study 4,800 webpages, number of accesses and users, IP addresses, time of visits and return ratio, among other variables. We compared the mean annual access using a confidence level of 95%.
Results: Over the 48 months of observation, there was a progressive increase in access to INCA's webpage, which is consistent with the increasing use internet as a health information source in Brazil.
The average number of accesses on prevention/protection pages during the first summer was 1141 (CI95% 968-1314) with 10 visits less then Annual Mean (AM); in the 2nd summer 1799 accesses (1612-1986) 186 access above AM; 3rd summer with 2426 accesses (2130-2721) 315 above AM; and 4th summer with 3102 accesses (2106-4098) 275 less then AM. All the oscillations in summer accesses means were within the Confidence Interval of AM.
Conclusion: we couldn't find significant difference between summer months and annual means. By the log files tracking employed, the perceived overexposure to sun during Brazilian summer couldn't raise significant attention towards information on UV protection and SSE.
