To examine associations between glucoregulation and 3 categories of psychological resources: hedonic well-being (i.e., life satisfaction, positive affect), eudaimonic well-being (i.e., personal growth, purpose in life, ikigai), and interdependent well-being (i.e., gratitude, peaceful disengagement, adjustment) among Japanese adults. The question is important given increases in rates of type 2 diabetes in Japan in recent years, combined with the fact that most prior studies linking psychological resources to better physical health have utilized Western samples.
Data came from the Midlife in Japan Study involving randomly selected participants from the Tokyo metropolitan area, a subsample of whom completed biological data collection (N = 382; 56.0% female; M(SD)age = 55.5(14.0) years). Glycosylated hemoglobin (HbA1c) was the outcome. Models adjusted for age, gender, educational attainment, smoking, alcohol, chronic conditions, body mass index (BMI), use of antidiabetic medication, and negative affect.
Purpose in life (β = -.104, p = .021) was associated with lower HbA1c, and peaceful disengagement (β = .129, p = .003) was associated with higher HbA1c in fully adjusted models. Comparable to the effects of BMI, a 1 standard deviation change in well-being was associated with a .1% change in HbA1c.
Associations among psychological resources and glucoregulation were mixed. Healthy glucoregulation was evident among Japanese adults with higher levels of purpose in life and lower levels of peaceful disengagement, thereby extending prior research from the United States. The results emphasize the need for considering sociocultural contexts in which psychological resources are experienced in order to understand linkages to physical health. (PsycINFO Database Record
探讨日本成年人的血糖调节与三类心理资源之间的关联，这三类心理资源分别是享乐幸福感（即生活满意度、积极情绪）、自我实现幸福感（即个人成长、生活目标、生活意义）和相互依存幸福感（即感恩、平和超脱、适应能力）。鉴于近年来日本2型糖尿病发病率上升，且之前大多数将心理资源与更好的身体健康联系起来的研究都采用了西方样本，因此这个问题很重要。
数据来自日本中年研究，参与者是从东京都市区随机选取的，其中一部分子样本完成了生物数据收集（N = 382；56.0%为女性；平均年龄（标准差）= 55.5（14.0）岁）。糖化血红蛋白（HbA1c）是研究结果指标。模型对年龄、性别、教育程度、吸烟、饮酒、慢性病、体重指数（BMI）、抗糖尿病药物使用情况和消极情绪进行了调整。
在完全调整后的模型中，生活目标（β = -0.104，p = 0.021）与较低的HbA1c相关，而平和超脱（β = 0.129，p = 0.003）与较高的HbA1c相关。与BMI的影响相当，幸福感每变化1个标准差，HbA1c就会变化0.1%。
心理资源与血糖调节之间的关联是复杂的。在生活目标水平较高且平和超脱水平较低的日本成年人中，健康的血糖调节较为明显，从而扩展了美国之前的研究。结果强调，为了理解与身体健康的联系，需要考虑心理资源所处的社会文化背景。（PsycINFO数据库记录）
