The association between stroke and nutrition has recently been investigated. However, the association between diet and stroke in Japan has not been clarified. We hypothesized that there may be an association between consumption of ramen and stroke mortality. Therefore, we investigated the association between the prevalence of ramen restaurants and stroke mortality in Japanese prefectures.
We used Pearson's correlation coefficients to evaluate associations between the prevalence of each of four restaurant types (ramen, fast food, French or Italian, and udon or soba) and age- and sex-adjusted stroke mortality rates in each prefecture. We also investigated correlations between acute myocardial infarction and the prevalence of each type of restaurant as a control. We obtained age- and sex-adjusted stroke mortality rates and the acute myocardial infarction mortality rate in each prefecture from the 2017 Trends in National Health published in Japan. Data on the number of restaurants of each type in each prefecture were obtained from the database of the Nippon Telegraph and Telephone Corporation.
The prevalence of ramen restaurants, but not of other restaurant types, positively correlated with stroke mortality in both men and women (r > 0.5). We found no correlation between ramen restaurant prevalence and mortality from acute myocardial infarction.
The prevalence of ramen restaurants in Japanese prefectures has a significant correlation with the stroke mortality rate.
最近研究了中风与营养之间的关联。然而，日本饮食与中风之间的关系尚未阐明。我们假设拉面的消费与中风死亡率之间可能存在关联。因此，我们调查了日本各县拉面餐厅的流行程度与中风死亡率之间的关系。
我们使用皮尔逊相关系数评估了每种餐厅类型（拉面、快餐、法式或意式、乌冬面或荞麦面）的流行程度与每个县的年龄和性别调整后的中风死亡率之间的关联。我们还调查了每种餐厅类型的流行程度与急性心肌梗死之间的相关性作为对照。我们从日本发布的 2017 年《国家健康趋势》中获得了每个县的年龄和性别调整后的中风死亡率和急性心肌梗死死亡率数据。每个县每种类型餐厅数量的数据来自日本电报电话公司的数据库。
无论是男性还是女性，拉面餐厅的流行程度都与中风死亡率呈正相关（r > 0.5），而其他类型餐厅的流行程度则没有相关性。我们没有发现拉面餐厅流行程度与急性心肌梗死死亡率之间的相关性。
日本各县拉面餐厅的流行程度与中风死亡率显著相关。
