BACKGROUND
The human papillomavirus (HPV) vaccine is recommended for adolescents and young adults to prevent HPV-related cancers and genital warts. However, HPV vaccine uptake among the target age groups is suboptimal.
OBJECTIVE
The aim of this infodemiology study was to examine public online searches in the United States related to the HPV vaccine from January 2010 to December 2021.
METHODS
Google Trends (GT) was used to explore online searches related to the HPV vaccine from January 1, 2010, to December 31, 2021. Online searches and queries on the HPV vaccine were investigated using relative search volumes (RSVs). Analysis of variance was performed to investigate quarterly differences in HPV vaccine searches in each year from 2010 to 2021. A joinpoint regression was used to identify statistically significant changes over time; the α level was set to .05.
RESULTS
The year-wise online search volume related to the HPV vaccine increased from 2010 to 2021, often following federal changes related to vaccine administration. Joinpoint regression analysis showed that HPV vaccine searches significantly increased on average by 8.6% (95% CI 5.9%-11.4%) across each year from 2010 to 2021. Moreover, HPV vaccine searches demonstrated a similar pattern across years, with search interest increasing through August nearly every year. At the state level, the highest 12-year mean RSV was observed in California (59.9, SD 14.3) and the lowest was observed in Wyoming (17.4, SD 8.5) during the period of 2010-2021.
CONCLUSIONS
Online searches related to the HPV vaccine increased by an average of 8.6% across each year from 2010 to 2021, with noticeable spikes corresponding to key changes in vaccine recommendations. We identified patterns across years and differences at the state level in the online search interest related to the HPV vaccine. Public health organizations can use GT as a tool to characterize the public interest in and promote the HPV vaccine in the United States.
背景
人乳头瘤病毒 (HPV) 疫苗被推荐用于青少年和年轻人，以预防 HPV 相关癌症和生殖器疣。然而，目标年龄组的 HPV 疫苗接种率并不理想。
目的
本项infodemiology 研究旨在调查 2010 年 1 月至 2021 年 12 月期间美国公众对 HPV 疫苗的在线搜索情况。
方法
使用 Google Trends（GT）来探索 2010 年 1 月 1 日至 2021 年 12 月 31 日期间与 HPV 疫苗相关的在线搜索。使用相对搜索量 (RSV) 调查对 HPV 疫苗的在线搜索和查询。采用方差分析 (ANOVA) 分析 2010 年至 2021 年每年 HPV 疫苗搜索的季度差异。采用 joinpoint 回归确定随时间的统计学显著变化；α 水平设置为.05。
结果
2010 年至 2021 年，与 HPV 疫苗相关的在线搜索量逐年增加，这通常与疫苗管理的联邦变化有关。Joinpoint 回归分析显示，2010 年至 2021 年，HPV 疫苗搜索量平均每年增加 8.6%（95%CI 5.9%-11.4%）。此外，HPV 疫苗搜索在各年呈现出相似的模式，每年 8 月之前搜索兴趣呈上升趋势。在州一级，2010 年至 2021 年期间，加利福尼亚州的 12 年平均 RSV 最高（59.9，SD 14.3），怀俄明州最低（17.4，SD 8.5）。
结论
2010 年至 2021 年，每年 HPV 疫苗相关的在线搜索量平均增加 8.6%，在疫苗推荐的关键变化时出现明显峰值。我们确定了各年的模式以及 HPV 疫苗在线搜索的州一级差异。公共卫生组织可以使用 GT 作为工具来描述美国公众对 HPV 疫苗的兴趣并推广 HPV 疫苗。
