背景：尽管流感相关疾病具有高风险和经济负担，但约三分之一的65岁及以上成年人仍放弃每年接种流感疫苗。大众传媒作为公众健康信息的主要来源，可以影响和促进健康行为，如接种疫苗。然而，关于媒体报道对流感疫苗接种影响的经验证据仍然有限。目的：探讨按月媒体报道对老年人流感疫苗接种的影响。方法：本研究利用流感相关新闻报道数量随月份和季节的变化，并在具有状态固定效应和季节性随机效应的线性概率模型中检验其对疫苗摄取的影响。我们结合了2010-2017年来自行为风险因素监测系统（BRFSS）的个人流感疫苗接种数据、NewsBank数据库的媒体报道数据以及其他几个数据源，包括来自全球历史气候网络的天气数据和来自疾病控制与预防中心的FluView流感季节数据。结果：我们的主要结果表明，10月份每增加100篇关于流感的媒体报道，65岁以上人群的疫苗接种率就会增加0.3个百分点。这个协会在1月举行，但不是在11月或12月。在流感高峰期的后期和疫苗非常有效的季节，这种情况更为明显。结论：本研究提供了提示性证据，表明媒体报道数量的变化与流感疫苗接种的变化有关。(C) 2019 Elsevier Ltd.版权所有。
Background: Despite the high risk and economic burden of influenza-related diseases, about one-third of adults aged 65 and older still forego annual influenza vaccination. Mass media, as a leading source of health information for the public, can influence and promote health behaviors, such as vaccination. However, empirical evidence on the effect of media coverage on influenza vaccination uptake remains limited.Objective: We examine the impact of media coverage by month on influenza vaccination among the elderly.Methods: This study exploits variation in the number of influenza-related news reports by month and across seasons and examines its impact on vaccine uptake in a linear probability model with state fixed effects and seasonable random effects. We combine individual-level influenza vaccination data from the Behavioral Risk Factor Surveillance System (BRFSS), 2010-2017, and media coverage data from the NewsBank database along with several other data sources including weather data from the Global Historical Climatology Network and data on the influenza season from FluView from the Centers for Disease Control and Prevention.Results: Our main results indicate every 100 additional media reports about influenza published in October were associated with an increase in the vaccination uptake rate among those aged 65+ of 0.3 percentage points. This association holds in January, but not in November or December. It was more pronounced in late-peak seasons and in seasons where the vaccine was highly effective.Conclusion: This study provides suggestive evidence that variation in the number of media reports is associated with variation in influenza vaccination uptake.
