Social relationships play a critical role in health and well-being throughout life. We analyzed the genetic and environmental variance co-variance structure for social support and strain across four sets of relationships including with one's co-twin, spouse/partner, family and friends. The sample included 5288 Norwegian twins aged 40-80. Older people reported less support from their co-twin and friends and less strain from their family and friends. Genetic influences contribute importantly to variation across all the measures, with estimates ranging from 0 to 58%; variance due to shared environmental influences was most important for the twin-relationship, ranging from 0.11 to 0.42%. Social support was negatively correlated with social strain across all sets of relationships. With the exception of the co-twin relationship, these associations were primarily mediated by genetic and non-shared environmental effects.
社会关系在人的一生中对健康和幸福起着至关重要的作用。我们分析了四组关系（包括同卵双胞胎、配偶/伴侣、家人和朋友）中社会支持和压力的遗传与环境方差协方差结构。样本包括5288名年龄在40至80岁之间的挪威双胞胎。老年人报告称从同卵双胞胎和朋友那里获得的支持较少，来自家人和朋友的压力也较小。遗传影响对所有测量指标的变异都有重要贡献，估计范围从0%到58%；共同环境影响导致的方差对双胞胎关系最为重要，范围从0.11%到0.42%。在所有关系组中，社会支持与社会压力呈负相关。除了同卵双胞胎关系外，这些关联主要由遗传和非共享环境效应介导。
