Among life-style factors affecting mental health, dietary habits are becoming a public health concern in their relation to psychological distress and social capital. We examined associations between interest in dietary pattern, social capital, and psychological distress with a population-based cross-sectional study in rural Japan.
A total of 16,996 residents of a rural town in northern Japan aged 30-79 years participated in this questionnaire survey. The questionnaire gathered data about socio-demographic variables, psychological distress, issues related to dietary habits, including interest in dietary pattern, and the social capital factors of reciprocity and sense of community belonging. Factors related to psychological distress were analyzed by using multiple logistic regression analysis.
A high interest in dietary pattern was significantly associated with a high level of social capital. In addition, an association between interest in dietary pattern and frequencies of intake of vegetables and fruits was confirmed. The multiple logistic regression analyses showed significant associations between interest in dietary pattern, social capital, frequency of intake of vegetables, and psychological distress after adjusting for socio-demographic variables. Low interest in dietary pattern was positively associated with psychological distress after adjusting for socio-demographic variables (OR = 2.18; 95%CI: 1.69-2.81). Low levels of both reciprocity and sense of community belonging were associated with psychological distress after adjusting for socio-demographic variables (OR = 3.46 with 95%CI of 2.10-5.71 for reciprocity, and OR = 7.42 with 95%CI of 4.64-11.87 for sense of community belonging).
Low interest in dietary pattern, low frequency of intake of vegetables, and low levels of social capital were significantly associated with psychological distress after adjusting for socio-demographic variables.
在影响心理健康的生活方式因素中，饮食习惯因其与心理困扰和社会资本的关系正成为一个公共卫生问题。我们在日本农村地区进行了一项基于人群的横断面研究，以探讨饮食模式兴趣、社会资本和心理困扰之间的关联。
日本北部一个农村城镇的16996名年龄在30 - 79岁的居民参与了这项问卷调查。问卷收集了社会人口统计学变量、心理困扰、与饮食习惯相关的问题（包括对饮食模式的兴趣）以及互惠和社区归属感等社会资本因素的数据。使用多元逻辑回归分析来分析与心理困扰相关的因素。
对饮食模式的高兴趣与高水平的社会资本显著相关。此外，还证实了饮食模式兴趣与蔬菜和水果摄入频率之间的关联。多元逻辑回归分析显示，在调整社会人口统计学变量后，饮食模式兴趣、社会资本、蔬菜摄入频率与心理困扰之间存在显著关联。在调整社会人口统计学变量后，对饮食模式的低兴趣与心理困扰呈正相关（OR = 2.18；95%CI：1.69 - 2.81）。在调整社会人口统计学变量后，互惠和社区归属感水平低均与心理困扰相关（互惠的OR = 3.46，95%CI为2.10 - 5.71；社区归属感的OR = 7.42，95%CI为4.64 - 11.87）。
在调整社会人口统计学变量后，对饮食模式的低兴趣、蔬菜摄入频率低和社会资本水平低与心理困扰显著相关。
