Abstract

BACKGROUND

Obesity is highly correlated with the development of chronic diseases and has become a critical public health issue that must be countered by aggressive action. This study determined whether data from Google Trends could provide insight into trends in obesity-related search behaviors in Taiwan.

OBJECTIVE

Using Google Trends, we examined how changes in economic conditions-using business cycle indicators as a proxy-were associated with people's internet search behaviors related to obesity awareness, health behaviors, and fast food restaurants.

METHODS

Monthly business cycle indicators were obtained from the Taiwan National Development Council. Weekly Taiwan Stock Exchange (TWSE) weighted index data were accessed and downloaded from Yahoo Finance. The weekly relative search volumes (RSV) of obesity-related terms were downloaded from Google Trends. RSVs of obesity-related terms and the TWSE from January 2007 to December 2011 (60 months) were analyzed using correlation analysis.

RESULTS

During an economic recession, the RSV of obesity awareness and health behaviors declined (r=.441, P<.001; r=.593, P<.001, respectively); however, the RSV for fast food restaurants increased (r=-.437, P<.001). Findings indicated that when the economy was faltering, people tended to be less likely to search for information related to health behaviors and obesity awareness; moreover, they were more likely to search for fast food restaurants.

CONCLUSIONS

Macroeconomic conditions can have an impact on people's health-related internet searches.

摘要

背景

肥胖与慢性病的发展高度相关，已成为一个必须通过积极行动加以应对的关键公共卫生问题。本研究确定谷歌趋势数据是否能洞察台湾地区与肥胖相关的搜索行为趋势。

目的

利用谷歌趋势，我们研究了以商业周期指标为代理的经济状况变化如何与人们在肥胖认知、健康行为和快餐店方面的网络搜索行为相关联。

方法

月度商业周期指标取自台湾国家发展委员会。台湾证券交易所（TWSE）加权指数的每周数据从雅虎财经获取并下载。肥胖相关术语的每周相对搜索量（RSV）从谷歌趋势下载。使用相关分析对2007年1月至2011年12月（60个月）期间肥胖相关术语的RSV和TWSE进行分析。

结果

在经济衰退期间，肥胖认知和健康行为的RSV下降（分别为r = 0.441，P < 0.001；r = 0.593，P < 0.001）；然而，快餐店的RSV增加（r = -0.437，P < 0.001）。研究结果表明，当经济衰退时，人们往往不太可能搜索与健康行为和肥胖认知相关的信息；此外，他们更有可能搜索快餐店。

结论

宏观经济状况会对人们与健康相关的网络搜索产生影响。
