Midlife Health in Japan (MIDJA) and the U.S. (MIDUS)

我们建议对日本成年人(N=1,000，除以1,000)进行一项调查 性别)，年龄在30岁至70岁之间，来自东京都。将收集有关社会人口统计的数据 特征(年龄、性别、婚姻状况、教育状况、收入)、心理社会特征(例如， 独立/相互依赖、个性特征、控制感、目标取向、社会支持、家庭 义务、社会责任)、精神健康(抑郁、焦虑、幸福感、生活满意度)； 身体健康(慢性病、健康症状、功能缺陷、健康行为)。这些 这些指标与被称为MIDUS的全国中年美国人纵向样本中的指标相似。这个 中心目标是比较日本样本(MIDJA)和美国样本(MIDUS)，以测试 假设相互依赖的结构预示着日本的幸福和健康，而 在美国，独立的结构预示着幸福和健康。我们还预测 健康和幸福，一些人提出了文化上的相似之处(例如，随着年龄的增长，生活目标不断下降)和 其他表明文化差异(例如，在日本，幸福的其他方面的年龄增长更多 与美国相比)。我们还建议收集大约一半的日本调查的生物标志物 样本(n=500)。我们将包括神经内分泌调节、免疫功能和 心血管风险。这些评估将与正在进行的中期开发和评估II P01项目4中的生物学评估并行。 因此，在这两种文化中，我们将检查心理社会因素和生物学之间的联系，以测试 假设相互依赖的结构与日本的生物风险有更强的联系， 然而，在美国，独立性的构建与生物风险的联系更紧密。 综合目标是将社会人口、心理社会和报告的健康评估结合起来，以确定 (通过递归分区)通向高或低不平衡负载的特定于文化的途径(多系统指标 生物风险)。自我们上次提交以来，我们已经在初步研究中添加了广泛的发现 证明(用试点数据)支持我们的指导性假设，并记录我们的 建议收集生物数据。

We propose to conduct a survey with a probability sample of Japanese adults (N = 1,000, divided equally by gender) aged 30 to 70 from the Tokyo metropolitan area. Data will be collected on sociodemographic characteristics (age, gender, marital status, educational status, income), psychosocial characteristics (e.g., independence/interdependence, personality traits, sense of control, goal orientations, social support, family obligation, social responsibility), mental health (depression, anxiety, well-being, life satisfaction), and physical health (chronic conditions, health symptoms, functional limitations, health behaviors). These measures parallel those in a national longitudinal sample of midlife Americans known as MIDUS. The central objective is to compare the Japanese sample (MIDJA) with the U.S. sample (MIDUS) to test the hypothesis that the construct of interdependence predicts well-being and health in Japan, whereas the construct of independence predicts well-being and health in the U.S. We also predict age differences in health and well-being, some suggesting cultural similarities (e.g., declining purpose in life with age) and others indicating cultural differences (e.g., more age increments on other aspects of well-being in Japan compared to the U.S.). We also propose to collect biomarkers on approximately half of the Japanese survey sample (n = 500). We will include assessments of neuroendocrine regulation, immune function, and cardiovascular risk. These will parallel biological assessments in Project 4 of the ongoing MIDUS II P01. Thus, in both cultures we will examine linkages between psychosocial factors and biology to test the hypothesis that the construct of interdependence is more strongly linked with biological risk in Japan, whereas the construct of independence is more strongly linked with biological risk in the U.S. A final integrative goal is to combine sociodemographic, psychosocial, and reported health assessments to identify (via recursive partitioning) culture-specific pathways to high or low allostatic load (a multi-system indicator of biological risk). Since our prior submission, we have added extensive findings to Preliminary Studies that demonstrate (with pilot data) support for our guiding hypotheses and also document the feasibility of our proposed biological data collection.
