This study examines the association between Meat, Egg, and Dairy (MED) product consumption and depressive symptoms among older adults in China, focusing on rural/urban and gender differences.
This study employed data from the latest wave (year 2018) of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), and Ordinary Least Squares (OLS) models were applied to examine the association between MED consumption and depression levels.
The findings revealed a consistent negative relationship between MED consumption and depression, with higher MED intake associated with lower depression levels. Urban residents and males exhibited higher MED consumption, which correlated with less depressive symptoms. However, the impact of MED consumption on depression varied by subgroups; urban older adults benefited more from MED consumption than their rural counterparts, and the relationship between MED intake and depression was more pronounced in males than in females. The study highlighted the influence of socio-demographic factors, such as literacy, income, and self-rated health, on depression levels.
The results suggested that MED consumption may offer protective effects on mental health in older adults, although the association may not be causal. The study underscored the need for further research to explore the complex interplay between diet and mental health in older adults, particularly in diverse cultural contexts.
本研究探讨了中国老年人肉类、蛋类和奶制品（MED）消费与抑郁症状之间的关联，重点关注农村/城市以及性别差异。
本研究采用了中国健康与养老追踪调查（CLHLS）最新一轮（2018年）的数据，并应用普通最小二乘法（OLS）模型来检验MED消费与抑郁水平之间的关联。
研究结果显示，MED消费与抑郁之间存在一致的负相关关系，MED摄入量越高，抑郁水平越低。城市居民和男性的MED消费量较高，这与较少的抑郁症状相关。然而，MED消费对抑郁的影响因亚组而异；城市老年人从MED消费中受益比农村老年人更多，并且MED摄入量与抑郁之间的关系在男性中比在女性中更明显。该研究强调了社会人口学因素，如识字率、收入和自评健康状况，对抑郁水平的影响。
结果表明，MED消费可能对老年人的心理健康具有保护作用，尽管这种关联可能不是因果关系。该研究强调需要进一步研究，以探索老年人饮食与心理健康之间的复杂相互作用，特别是在不同文化背景下。
