Background We evaluated (1) whether the public interest in prostate cancer and prostate cancer screening increased following Prostate Cancer Awareness Month (PCAM) and (2) whether PCAM was as effective as Breast Cancer Awareness Month (BCAM) at generating public interest. Methods Using Google Trends, we measured search volume in PCAM and BCAM. We used the search volume in Google Trends as a proxy for changes in public interest from January 01, 2009 to December 31, 2018 worldwide, including the specific keywords: "Prostate Cancer"; "Prostate-Specific Antigen"; "Prostate Cancer Screening"; "Prostate Cancer Management"; "Breast Cancer"; "Breast Cancer Screening"; "Mammography"; and "Breast Cancer Management". Also, we measured tweets containing "prostate cancer" and "breast cancer". We used an autoregressive integrated moving algorithm (ARIMA) to forecast expected weekly search volumes during PCAM and BCAM. We then compared the Google Trends data from during PCAM and BCAM to the forecasted values and determined a "greater than expected" range. Results The mean pooled percent increase in tweets associated with "prostate cancer" during PCAM from 2012 through 2018 was 15.9% (95% CI, -1% - 33%). The mean pooled percent increase in tweets associated with "breast cancer" during BCAM from 2012 through 2018 was 318.5% (95% CI, 268% - 369%). BCAM was associated with a 302.6% greater effect on increasing tweets referencing the disease of interest than PCAM from 2012-2018. "Breast cancer" Google searches were found to be 36.7% (95% CI, 34% - 39%) more frequent than "prostate cancer" per month from 2009-2019. Google Searches for "breast cancer screening" were 29.6% (95% CI, 28% - 31%) greater than "prostate cancer screening". Conclusions Our results indicate that PCAM is not generating substantial internet interest, especially when compared to BCAM. The search volume for Google Trends search terms related to PCAM was less than BCAM in every comparison, and Twitter indicated only a slight increase of Tweets during the month of PCAM. Suggestions are provided to improve the effect of PCAM and men's health.
背景 我们评估了：（1）在前列腺癌宣传月（PCAM）之后，公众对前列腺癌及前列腺癌筛查的兴趣是否增加；（2）PCAM在激发公众兴趣方面是否与乳腺癌宣传月（BCAM）同样有效。方法 使用谷歌趋势，我们测量了PCAM和BCAM期间的搜索量。我们将谷歌趋势中的搜索量作为2009年1月1日至2018年12月31日全球范围内公众兴趣变化的一个指标，包括特定关键词：“前列腺癌”；“前列腺特异性抗原”；“前列腺癌筛查”；“前列腺癌管理”；“乳腺癌”；“乳腺癌筛查”；“乳房X线摄影术”；以及“乳腺癌管理”。此外，我们测量了包含“前列腺癌”和“乳腺癌”的推文。我们使用自回归积分移动平均算法（ARIMA）来预测PCAM和BCAM期间的预期每周搜索量。然后，我们将PCAM和BCAM期间的谷歌趋势数据与预测值进行比较，并确定一个“高于预期”的范围。结果 2012年至2018年PCAM期间，与“前列腺癌”相关的推文的平均合并百分比增幅为15.9%（95%置信区间，-1% - 33%）。2012年至2018年BCAM期间，与“乳腺癌”相关的推文的平均合并百分比增幅为318.5%（95%置信区间，268% - 369%）。2012 - 2018年，BCAM在增加提及目标疾病的推文方面的效果比PCAM大302.6%。2009 - 2019年，每月“乳腺癌”的谷歌搜索频率比“前列腺癌”高36.7%（95%置信区间，34% - 39%）。谷歌对“乳腺癌筛查”的搜索比“前列腺癌筛查”多29.6%（95%置信区间，28% - 31%）。结论 我们的结果表明，PCAM并未引起大量的网络关注，尤其是与BCAM相比。在每次比较中，与PCAM相关的谷歌趋势搜索词的搜索量都低于BCAM，而且推特显示在PCAM月期间推文仅略有增加。我们提供了一些建议以提高PCAM和男性健康的效果。
