What is the Relationship of to Physical ?

2008 Headlines/Trends Decades of research suggest that a stable marriage protects adult partners against premature death and illness, and provides children with the best physical health outcomes. The relationship of marriage to bet- ter health outcomes continues to be found in the most recent national health surveys and longitudinal stud- ies. These studies indicate married adults live longer and enjoy better physical health than adults who are never married, divorced, separated or widowed. In fact, these benefits seem to persist even when factors that affect health outcomes, such as health Studies reviewed by Wood et al in a recent synthesis status prior to marriage, income levels and race/ article show that marriage also benefits the health ethnicity are taken into account (Johnson et al, 2000; of children.
