Observing the dietary principles of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet has exhibited an association with a diminished occurrence of diverse ailments, enhanced mental well-being, and extended longevity. Nevertheless, current literature is deficient in terms of investigating the link between the MIND diet and subjective well-being (SWB) specifically in older adults. Hence, this study endeavors to examine the correlation between adhering to a Chinese-modified Mediterranean-DASH Intervention for Neurodegenerative Delay (cMIND) diet and SWB in the older Chinese adults, taking into account the unique dietary attributes of the Chinese population.
Using data from the latest four waves of the Chinese Longitudinal Healthy Longevity Survey. Multiple linear regression and multinomial ordered logistic regression were employed to examine the relationship between the duration of adherence to cMIND diet and SWB in Chinese older adults.
The results indicated a significant association between the duration of adherence to cMIND diet and SWB (1 ∼ 6 years: B = 0.907, 95%CI = 0.508 ∼ 1.307, P < 0.001; 7 ∼ 9 years: B = 1.286, 95%CI = 0.767 ∼ 1.805, P < 0.001; 10 years and above: B = 2.320, 95%CI = 1.677 ∼ 2.963, P < 0.001). The longer the duration of adherence to cMIND diet, the higher the scores for life satisfaction (B = 0.184, 95%CI = 0.110 ∼ 0.259; B = 0.312, 95%CI = 0.217 ∼ 0.407; B = 0.321, 95%CI = 0.193 ∼ 0.448), positive affect (B = 0.434, 95%CI = 0.209 ∼ 0.658; B = 0.701, 95%CI = 0.400 ∼ 1.003; B = 1.167, 95%CI = 0.775 ∼ 1.559), and negative affect (B = 0.289, 95%CI = 0.078 ∼ 0.500; B = 0.832, 95%CI = 0.479 ∼ 1.185), suggesting a higher SWB score. Sensitivity analysis further supports our findings.
Considering the poor knowledge, attitudes, and behaviors related to diet among Chinese adults, especially older adults, it is imperative to implement dietary policies that promote SWB in older adults to enhance their happiness in later life.
观察地中海饮食-得舒饮食干预神经退行性延迟（MIND）饮食的饮食原则与多种疾病发病率降低、心理健康状况改善和寿命延长有关。然而，目前的文献缺乏关于 MIND 饮食与老年人主观幸福感（SWB）之间联系的研究。因此，本研究旨在探讨在中国老年人中，遵循中国式改良地中海饮食-得舒饮食干预（cMIND）饮食与 SWB 之间的相关性，同时考虑到中国人群独特的饮食特征。
利用中国长寿老人健康长寿调查（CLHLS）最近四轮的数据。采用多元线性回归和多项有序逻辑回归分析 cMIND 饮食坚持时间与中国老年人 SWB 之间的关系。
cMIND 饮食坚持时间与 SWB 呈显著正相关（1 至 6 年：B=0.907，95%CI=0.508 至 1.307，P<0.001；7 至 9 年：B=1.286，95%CI=0.767 至 1.805，P<0.001；10 年及以上：B=2.320，95%CI=1.677 至 2.963，P<0.001）。cMIND 饮食坚持时间越长，生活满意度评分越高（B=0.184，95%CI=0.110 至 0.259；B=0.312，95%CI=0.217 至 0.407；B=0.321，95%CI=0.193 至 0.448），积极情绪评分越高（B=0.434，95%CI=0.209 至 0.658；B=0.701，95%CI=0.400 至 1.003；B=1.167，95%CI=0.775 至 1.559），消极情绪评分越低（B=0.289，95%CI=0.078 至 0.500；B=0.832，95%CI=0.479 至 1.185），表明 SWB 评分越高。敏感性分析进一步支持了我们的发现。
考虑到中国成年人，尤其是老年人，对饮食相关知识、态度和行为的认知较差，有必要实施促进老年人 SWB 的饮食政策，以提高他们晚年的幸福感。
