Existing research indicates that the Mediterranean diet has a positive impact on preventing and treating hypertension. However, its specific effect on hypertension among elderly Chinese individuals is unclear.
The objective of this research was to explore the association between the Chinese version of the Mediterranean-DASH Intervention for Neurodegenerative Delay (cMIND) diet and hypertension among elderly Chinese individuals, aiming to offer novel strategies for alleviating the burden of hypertension in this demographic.
In this study, we used cross-sectional data published in 2018 by the China Longitudinal Health and Longevity Survey (CLHLS) to develop a binary logistic regression model to investigate the correlation between cMIND diet and hypertension in a Chinese elderly population. Restricted cubic spline was used to test for linear associations, and further subgroup analyses were performed to test for interactions.
In total, 7,103 older adults were included in the study, with a prevalence of hypertension of 39.0%. When the cMIND diet score was used as a continuous variable, a significant protective effect against hypertension was present (OR = 0.955, 95% CI:0.923-0.988, p = 0.008); when used as a categorical variable, this protective effect was still present at higher levels (compared to lower levels) of the cMIND diet (OR = 0.869, 95% CI: 0.760-0.995, p = 0.042).
Although the Mediterranean diet has great potential to reduce the chance of hypertension, it should also consider the effect on the Chinese population. The results of this study provide new ways to reduce the disease burden of hypertension in Chinese older adults and improve quality of life in later life.
The cMIND diet can considerably reduce the risk of hypertension among older adults in China.
现有研究表明，地中海饮食对预防和治疗高血压有积极影响。然而，其对中国老年人群高血压的具体影响尚不清楚。
本研究旨在探讨中国版地中海- DASH 干预神经退行性延迟饮食（cMIND）与中国老年人群高血压之间的关系，旨在为缓解该人群高血压负担提供新策略。
本研究使用 2018 年中国健康与长寿纵向研究（CLHLS）发表的横断面数据，构建二元逻辑回归模型，探讨中国老年人群 cMIND 饮食与高血压的相关性。采用限制性三次样条检验线性关联，并进行进一步的亚组分析以检验交互作用。
共纳入 7103 名老年人，高血压患病率为 39.0%。当 cMIND 饮食评分作为连续变量时，与高血压呈显著保护相关（OR=0.955，95%CI：0.923-0.988，p=0.008）；当作为分类变量时，这种保护作用在 cMIND 饮食较高水平（与较低水平相比）时仍然存在（OR=0.869，95%CI：0.760-0.995，p=0.042）。
尽管地中海饮食具有降低高血压风险的巨大潜力，但也应考虑其对中国人群的影响。本研究结果为降低中国老年人群高血压疾病负担、提高晚年生活质量提供了新方法。
cMIND 饮食可显著降低中国老年人群高血压风险。
