How do close relationships lead to longer life?


While recent research has shown that loneliness can play a role in early death, psychologists are also concerned with the mechanisms by which social relationships and close personal ties affect health. A special issue of American Psychologist, the flagship journal of the American Psychological Association, offers an overview of the science and makes the case for psychological scientists to work together to make close relationships a public health priority.

Among the articles:
"Advancing Social Connection as a Public Health Priority in the United States," by Julianne Holt-Lunstad, PhD, Brigham Young University; Theodore Robles, PhD, University of California Los Angeles; and David Sbarra, PhD, University of Arizona.

This article outlines the potential and promise of elevating social connection as a public health priority. A robust body of scientific evidence suggests that being in high quality close relationships and feeling socially connected are associated with decreased risk of mortality. Social isolation, loneliness and relationship discord are well-established risk factors for poor health. Despite the importance of social connection for good health, government agencies, health care providers and health care funders have been slow to recognize social connection as a public health priority, according to the authors. They give an overview of the extent of the problem (as many as 43 percent of U.S. adults older than 60 experience frequent or intense loneliness) and provide suggestions on how to integrate social relationships into public health priorities by researching and developing interventions to improve social connection.

"Interpersonal Mechanisms Linking Close Relationships to Health" by Paula Pietromonaco, PhD, University of Massachusetts, Amherst, and Nancy Collins, PhD, University of California, Santa Barbara.

Close relationships can protect and promote health in various ways. This article provides an overview for understanding how interpersonal processes influence health and disease. For example, in times of stress, relationships can help protect against its negative effects, while in more peaceful times, relationships can foster positive emotions, personal growth and health-promoting behaviors. The authors also examine the negative health effects of social disconnection through hostile relationships or social rejection, as well as what is known about factors that influence these effects, such as emotion and biological factors.

"Childhood Close Family Relationships and Health" by Edith Chen, PhD, and Gregory Miller, PhD, Northwestern University, and Gene Brody, PhD, University of Georgia.

The relationships that children and adolescents have early in life can have important ramifications for health across the life span. Emotionally significant, comforting relationships during childhood are linked to better physical health from infancy to adulthood. Close family relationships can mitigate the impact of adversity on physical health across the life span. The authors propose a model to examine how aspects of family relationships -- such as support, conflict, obligations and parenting behaviors -- evolve over time and how these characteristics play a role in protecting against the health effects of childhood adversity.



"Integrative Pathways Linking Close Family Ties to Health: A Neurochemical Perspective" by Bert Uchino, PhD, University of Utah, and Baldwin Way, PhD, Ohio State University.

The quality of one's family life, for better or for worse, has been linked to physical health. As research increasingly documents these links, an important next step is to refine theoretical models and understand the biological mechanisms involved. This article uses the oxytocin system as an example of how complex biological pathways can link positive and negative family relationships to physical health. Oxytocin is a powerful hormone that is released in response to close relationships and helps facilitate bonding. But oxytocin can have other effects on health. It inhibits release of the hormone cortisol, reducing the negative effects of stress. There is also evidence, in animal models, that it can protect against heart attacks, high blood pressure and even obesity.
