德克萨斯大学圣安东尼奥分校的研究表明，中年时期的体育活动和健康血糖水平可能与日后认知能力下降速度较慢相关联1。该项长期追踪研究涵盖402名圣安东尼奥居民，其中平均年龄为57.9岁，58.5%为女性，52%为西班牙裔，其余为非西班牙裔白人1。
研究发现体育活动对西班牙裔成人的认知保护作用尤为显著，而空腹血糖读数为126毫克/分升或更低与非西班牙裔白人参与者认知衰退速度较慢相关1。这一发现具有重要意义，因为西班牙裔65岁以上老年人中约14%患有阿尔茨海默病，高于非西班牙裔白人的10%1。美国现有670万人患阿尔茨海默病1，而近40%的阿尔茨海默病病例可能与可改变的风险因素相关1。
研究的主导者之一Claudia Satizabal博士指出："通过改善心血管健康，有可能有意义地减轻阿尔茨海默病和其他痴呆症的公共卫生负担，特别是在高风险人群中"1。该研究于2026年7月23日发表在《阿尔茨海默病：衰老的行为与社会经济学》期刊上1。
Researchers at the University of Texas at San Antonio have found that physical activity and healthy blood sugar levels during middle age may be associated with slower cognitive decline in subsequent years.1 The longitudinal study tracked 402 San Antonio residents with an average age of 57.9 years, of whom 58.5% were women and 52% were Hispanic.1 The protective effects of physical activity proved particularly significant for Hispanic adults, while lower fasting blood glucose levels correlated with reduced cognitive decline among non-Hispanic white participants.1
The research underscores the importance of modifiable risk factors in brain health, as approximately 40% of Alzheimer's disease cases may be attributable to changeable lifestyle factors.1 Hispanic adults aged 65 and older experience higher rates of Alzheimer's disease at roughly 14%, compared with 10% among non-Hispanic white adults.1 Currently, approximately 6.7 million Americans are living with Alzheimer's disease.1 Fasting blood glucose readings of 126 milligrams per deciliter or lower showed an association with slower cognitive deterioration in non-Hispanic white study participants.1 According to Dr. Claudia Satizabal, "by improving cardiovascular health, it is possible to meaningfully reduce the public health burden of Alzheimer's disease and other dementias, particularly in high-risk populations."1 The findings were published on July 23, 2026, in the journal Alzheimer's Disease: Demography and Socioeconomics.1
