Abstract
A variety of research has documented the association between various measures of religion/spirituality and physical health outcomes. The purpose of this paper is to review the literature on this topic. The paper also discusses the mechanisms that are thought to underlie the associations found in the literature. Further, the paper presents several avenues along which future research might proceed in order to advance our understanding of these issues. The paper concludes by making a case for the need for empirical examinations of these issues in countries other than the United States. Particular focus is paid here to religion among older adults in Japan.
