Abstract：
Mental health is affected by both genetic and environmental factors. However, previous studies have showed conflict findings about the role of lifestyle and little is known about the situation of the Chinese population. The purpose of this study was to explore the relationship between the frequency of food consumption, physical exercise condition and mental health, as well as factors related to mental stress in Chinese.
We recruited 8160 residents who had health examinations in a public hospital during June 2016 to May 2018. Demographic characteristics, the frequency of food consumption, physical exercise condition and mental health status was collected by a questionnaire. We estimated the association using the odds ratio (OR) and 95% confidence interval (CI) based on Binary or ordinal logistic regression models. A classification and regression tree (CART) demonstrated the prediction of the value of a target variable based on other values.
The logistic regression model and classification tree model both found that the frequency of fresh vegetables or fruit and fried foods consumption and the current state of drinking alcohol were related to mental stress. The degree of mental stress reduced significantly with increasing consumption of fish (OR = 0.80, 95% CI: 0.71-0.90) and regular exercise (OR = 0.55, 95% CI:0.48-0.64) in females and increased consumption of fish (OR = 0.55, 95% CI: 0.48-0.64) and cereal crop (OR = 0.77, 95% CI: 0.68-0.89), fish (OR = 0.87, 95%CI:0.77-0.96) and regular exercise (OR = 0.61, 95%CI:0.53-0.70) in males. On the contrary, the frequency of consumption of desserts (OR = 1.43, 95% CI: 1.26-1.62) and the current of drinking alcohol (OR = 1.47, 95%CI:1.21-1.79) in females and meat (OR = 1.47, 95%CI: 1.31-1.65), pickled and smoked food (OR = 1.18, 95%CI:1.05-1.32) and the current state of drinking alcohol (OR = 1.25, 95%CI:1.12-1.40) in males were related to an increased risk of mental health.
Our study showed that both the frequency of some food consumption and physical exercise condition were associated with mental health and affected the degree of stress, which provided novel insights into interventions.

摘要：
心理健康受到遗传和环境因素的影响。然而,以前的研究表明，关于生活方式的作用存在冲突，而对中国人口的状况知之甚少。这项研究的目的是探讨食物消费频率之间的关系，体育锻炼条件和心理健康，以及与中国人的心理压力有关的因素。
我们招募了2016年6月至2018年5月在公立医院进行健康检查的8160名居民。人口特征，食物消费的频率，通过问卷调查收集体育锻炼情况和心理健康状况。我们使用基于二元或序数逻辑回归模型的比值比（OR）和95％置信区间（CI）来估计关联。分类和回归树（CART）演示了基于其他值的目标变量的值的预测。
Logistic回归模型和分类树模型均发现，新鲜蔬菜或水果和油炸食品的消费频率以及饮酒现状与精神压力有关。随着女性鱼类消费量（OR=0.80，95％CI：0.71-0.90）和定期运动（OR=0.55，95％CI：0.48-0.64）的增加以及鱼类消费量的增加，精神压力程度显着降低（OR=0.55，95％CI：0.48-0.64）和谷物作物（OR=0.77，95％CI：0.68-0.89），鱼类（OR=0.87，95CI：0.77-0.96）和定期运动（OR=0.61，95CI：0.53-0.70）。相反,女性和肉类的甜点消费频率（OR=1.43，95％CI：1.26-1.62）和饮酒电流（OR=1.47，95CI：1.21-1.79）（OR=1.47，95CI：1.31-1.65），腌制和熏制食物（OR=1.18，95CI：1.05-1.32）和男性饮酒现状（OR=1.25，95CI：1.12-1.40）与心理健康风险增加有关。
我们的研究表明，某些食物消耗的频率和体育锻炼状况都与心理健康有关，并影响压力的程度，这为干预措施提供了新的见解。
