症例数は男性の方が女性より多いものの、全ての年齢層に影響が及んでいるということ
Although the number of cases is higher in men than women, all age groups are affected.

中南大学湘雅医院の研究チームは世界204カ国・地域の気温と脳卒中について調査
A research team from Xiangya Hospital of Central South University investigated temperature and stroke in 204 countries and regions around the world.

世界の疾患、死亡、障害に関するデータと、気温や雲、天候に関するデータを使ってモデルを作成した
The model was created using data on global disease, death, and disability, as well as data on temperature, clouds, and weather.

研究者によれば、脳卒中の患者数は人口の高齢化と増加に伴って増加していたが、それだけではなく、「最適ではない気温」が関係していたことが分かった
Researchers found that the number of stroke cases was increasing as the population aged and grew, but not only because of ’suboptimal temperatures’.

陸上の気温が上昇すると極渦(北極・南極周辺に密集する寒気)に干渉し、これが弱まると気温が下がる
When the temperature on land rises, it interferes with the polar vortex (cold air that gathers around the North and South poles), and when this weakens, the temperature falls.

現時点で、極端な暑さや寒さに起因する脳卒中の死者は、アフリカのように貧困率が高く医療態勢が脆弱(ぜいじゃく)な地域に集中している
At present, deaths from stroke caused by extreme heat or cold are concentrated in areas with high poverty rates and weak medical systems, such as Africa.

しかし中央アジアで暑さに伴う脳卒中負担が急増している現状にも注意を要すると研究者は指摘
However, researchers point out that attention must be paid to the current situation where the burden of stroke due to heat is rapidly increasing in Central Asia.
