Background
Analysis of Internet search trends has been performed to evaluate interest in sun protection, artificial tanning, and skin cancers among the public, particularly in Western countries. This observational study aimed to investigate the relative popularity of search terms relating to sun protection, sunburn, skin cancers, and tanning used in Google TrendsÂź in three SouthâEast Asian countries (Malaysia, Singapore, and Indonesia).
Methods
The relevant search terms were queried using the Google TrendsÂź in each location and worldwide. The search volume indices were compared between locations and over a time period from January 1, 2004, to January 31, 2019. Correlations between âsunblockâ and âsunburnâ as well as âsunblockâ and search terms relating to skin cancers (âskin cancer,â âmelanoma,â âbasal cell carcinoma,â and âsquamous cell carcinomaâ) were evaluated.
Results
The favored search term relating to sun protection in this region was âsunblockâ despite the term itself being a misnomer. The relative popularity of searches for âsunblockâ also showed an increase over time and was generally higher compared with interest in sunburn, skin cancers, and artificial tanning practices. Positive correlations were noted between âsunblockâ and âsunburnâ in Malaysia and âsunblockâ and âmelanomaâ in Singapore.
Conclusion
Insights into search trends may assist public health promotion to raise awareness regarding sun protection and skin cancers in the region by targeting commonly used terms for each geographical location.
