Research on the relationship between vegetable consumption and stroke among the Chinese population is still rare. This study aimed to explore the association between vegetable consumption and stroke. Using data from the China Health and Nutrition Survey (1991-2018), we included 15,145 participants over 40 years old without stroke as the baseline. Participants were categorized into five groups according to vegetable consumption. The adjusted HRs of stroke associated with vegetable consumption were calculated using the COX proportional hazards model. During the follow-up, 504 stroke cases were detected (303 men and 201 women). For the females, compared with the Q1 group of vegetable consumption, the multivariable-adjusted HRs for stroke were 0.60 (95%CI 0.36, 1.00) in the group of Q4. No significant associations between vegetable consumption and stroke were found among males. Furthermore, compared with the Q1 group of dark vegetable consumption, for the whole subjects, the multivariable-adjusted HRs for stroke were 0.68 (95%CI 0.50, 0.92) in the group of Q4. For the females, compared with the Q1 group of dark vegetable consumption, the multivariable-adjusted HRs for stroke were 0.49 (95%CI 0.30, 0.80) in the group of Q4. In conclusion, this study suggested that vegetable consumption decreases the risk of stroke among Chinese females. In addition, the intake of dark vegetables was inversely associated with stroke.
在中国人群中，关于蔬菜摄入与中风之间关系的研究仍然很少。本研究旨在探讨蔬菜摄入与中风之间的关联。我们使用了中国健康与营养调查（1991-2018 年）的数据，纳入了 15145 名年龄在 40 岁以上且无中风的参与者作为基线人群。根据蔬菜摄入情况，将参与者分为五组。使用 COX 比例风险模型计算与蔬菜摄入相关的中风调整后的 HR。在随访期间，共检测到 504 例中风病例（303 名男性和 201 名女性）。对于女性，与蔬菜摄入量 Q1 组相比，蔬菜摄入量 Q4 组的中风多变量调整后的 HR 为 0.60（95%CI 0.36,1.00）。男性中蔬菜摄入量与中风之间未发现显著相关性。此外，与深色蔬菜摄入量 Q1 组相比，对于所有受试者，蔬菜摄入量 Q4 组的中风多变量调整后的 HR 为 0.68（95%CI 0.50,0.92）。对于女性，与深色蔬菜摄入量 Q1 组相比，蔬菜摄入量 Q4 组的中风多变量调整后的 HR 为 0.49（95%CI 0.30,0.80）。综上所述，本研究表明蔬菜摄入降低了中国女性中风的风险。此外，深色蔬菜的摄入量与中风呈负相关。
