This review focuses on the pathway leading from the marital relationship to
physical health. Evidence from 64 articles published in the past decade, p
articularly marital interaction studies, suggests that marital functioning
is consequential for health; negative dimensions of marital functioning hav
e indirect influences on health outcomes through depression and health habi
ts, and direct influences on cardiovascular, endocrine, immune, neurosensor
y, and other physiological mechanisms. Moreover, individual difference vari
ables such as trait hostility augment the impact of marital processes on bi
ological systems. Emerging themes in the past decade include the importance
of differentiating positive and negative dimensions of marital functioning
, the explanatory power of behavioral data, and gender differences in the p
athways from the marital relationship to physiological functioning. Contemp
orary models of gender that emphasize self-processes, traits, and roles fur
nish alternative perspectives on the differential costs and benefits of mar
riage for men's and women's health.
