Association between cMIND diet and hypertension among older adults in China: a nationwide survey.

Background: 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. Aims: 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. Methods: 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. Results: 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). Discussion: 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. Conclusion: The cMIND diet can considerably reduce the risk of hypertension among older adults in China. [ABSTRACT FROM AUTHOR]
