研究发现,通过伤害脑血管,BMI水平越高,血管痴呆的风险越高。 Higher BMI increases vascular dementia risk by harming brain blood vessels, study finds.

2026年1月22日发表的一份新研究报告提供了有力的证据,证明高体质指数(BMI)通过损害脑血管,直接增加了血管痴呆的风险,血管痴呆是第二常见的痴呆症。 A new study published on January 22, 2026, provides strong evidence that higher body mass index (BMI) directly increases the risk of vascular dementia, the second most common form of dementia, by damaging brain blood vessels. 研究人员利用遗传数据和先进的统计方法,对来自丹麦和联合王国的500 000多人进行了分析,发现BMI每上升4.5点与血管痴呆的风险明显增加有关,而高血压是这一联系的主要部分。 Using genetic data and advanced statistical methods, researchers analyzed over 500,000 individuals from Denmark and the UK and found that each 4.5-point rise in BMI correlated with a significantly higher risk of vascular dementia, with high blood pressure explaining a major portion of this link. 专家说,保持健康的体重和通过饮食、锻炼和定期监测来管理血压(最好是低于120/80毫米汞)有助于预防痴呆症,因为目前没有治疗方法。 Experts say maintaining a healthy weight and managing blood pressure through diet, exercise, and regular monitoring—ideally below 120/80 mm Hg—can help prevent dementia, as there is currently no cure. 研究结果支持这样一种观点,即心脏健康习惯保护大脑健康,并强调早期干预的重要性,尽管由于抽样中的多样性有限,研究的结果可能不完全适用于非白人人口。 The findings support the idea that heart-healthy habits protect brain health and highlight the importance of early intervention, though the study’s results may not fully apply to non-White populations due to limited diversity in the sample.
