摘要

社会支持通常被认为是影响健康的环境因素，尤其是在老龄人口中。然而，它的遗传基础表明其起源更为复杂。本研究通过对荷兰双胞胎登记处 2009 年至 2011 年间收集的大量成年双胞胎样本（N = 8019）数据应用阈值模型，研究了社会支持的遗传性。研究采用杜克大学-联合国大学功能性社会支持问卷来评估社会支持质量。我们的分析表明，社会支持的遗传贡献率估计为 37%，没有共同环境的贡献，男女之间的遗传率也没有差异。研究结果强调了社会支持作为一种受遗传和环境因素影响的特质的复杂性，对社会支持仅仅是一种环境结构的观点提出了质疑。

Genetic Influence on Social Support: A Twin Study.

Social support is often considered an environmental factor affecting health, especially in aging populations. However, its genetic underpinnings suggest a more complex origin. This study investigates the heritability of social support through applying a threshold model on data of a large adult sample of twins (N = 8019) from the Netherlands Twin Register, collected between 2009 and 2011. The study employed the Duke - UNC Functional Social Support Questionnaire to assess social support quality. Our analysis revealed genetic contributions to social support, with heritability estimated at 37%, without a contribution of shared environment and no differences between men and women in heritability. The study's results underscore the complexity of social support as a trait influenced by genetic and environmental factors, challenging the notion that it is solely an environmental construct.

期刊介绍： Twin Research and Human Genetics is the official journal of the International Society for Twin Studies. Twin Research and Human Genetics covers all areas of human genetics with an emphasis on twin studies, genetic epidemiology, psychiatric and behavioral genetics, and research on multiple births in the fields of epidemiology, genetics, endocrinology, fetal pathology, obstetrics and pediatrics. Through Twin Research and Human Genetics the society aims to publish the latest research developments in twin studies throughout the world.
