Abstract
Prosocial behavior during adolescence has been associated with better physical health, including slower epigenetic aging. However, little is known about the specific role of empathy in epigenetic aging and the mechanisms explaining this relationship. One such mechanism may be substance use, which is predicted by low empathy and contributes to accelerated epigenetic aging. Thus, the present study examined whether empathy during early adolescence predicts epigenetic aging in young adulthood and whether substance use in late adolescence and young adulthood mediates this effect. Participants included 343 individuals (58% female, 81% Black, 19% White) who were interviewed at mean ages of 13, 17, and 27 years. Participants self-reported their empathy at Time 1 and their alcohol, tobacco, and cannabis use at Times 2 and 3. At Time 3, epigenetic aging was assessed from salivary DNA using the GrimAge, DunedinPACE, and PhenoAge clocks. A regression analysis demonstrated that higher empathy in early adolescence uniquely predicted lower epigenetic aging on the GrimAge clock in young adulthood even after adjusting for environmental and sociodemographic risk factors. Mediation models revealed that the link between empathy and lower epigenetic aging on all three clocks was mediated by lower tobacco use. These results suggest that higher empathy during early adolescence may contribute to better health throughout the lifespan due to lower tobacco use and slower epigenetic aging.

期刊介绍：
Developmental Psychology ® publishes articles that significantly advance knowledge and theory about development across the life span. The journal focuses on seminal empirical contributions. The journal occasionally publishes exceptionally strong scholarly reviews and theoretical or methodological articles. Studies of any aspect of psychological development are appropriate, as are studies of the biological, social, and cultural factors that affect development. The journal welcomes not only laboratory-based experimental studies but studies employing other rigorous methodologies, such as ethnographies, field research, and secondary analyses of large data sets. We especially seek submissions in new areas of inquiry and submissions that will address contradictory findings or controversies in the field as well as the generalizability of extant findings in new populations. Although most articles in this journal address human development, studies of other species are appropriate if they have important implications for human development. Submissions can consist of single manuscripts, proposed sections, or short reports.
