Health disparities between African Americans (AA) and European Americans (EA) living in the USA, as well as disparities within each population are well documented. These disparities persist, even when socioeconomic and environmental factors are controlled, suggesting that some of the between group health disparity reflects the effects of non-economically based race-related experiences, such as racial discrimination, on psychological and physical health. In this project, we will document individual and group differences in trajectories of health and health-related behaviors from age 12 to age 32, focusing primarily on race, gender, and social class disparities. We will then evaluate the role of racial discrimination outside one?s home and socialization within one?s home in moderating the shape of these trajectories. Although some research has explored the impact of parent socialization on their children?s health and ability to cope with discrimination in the short term, little work has examined the role of parents and families on developmental health trajectories in the second and third decades of life. Using the Maryland Adolescent Development in Context Study (MADICS), a nationally-recognized 18-year longitudinal study of family, school, neighborhood, and peer influences on psychological, social, and physical development, we seek to understand the effects that parents have on the development of their children?s mental and physical health during the second and third decades of life. Specifically, we will create trajectories of physical health and health-related behaviors from approximately age 12 to approximately age 32 (Aim 1). Next, we will examine extent to which the individual differences in these health trajectories vary as a function of: (a) racial/ethnic (R/E) classification, gender, and SES; (b) individual differences in experiences of racial discrimination and other critical life events; and (c) other individual differences known to predict effective coping with stressors like racial discrimination (Aim 2). We will next create profiles of general and R/E specific parent socialization and examine their relations (Aim 3). Finally, we will examine the relation between these socialization profiles and trajectories of physical health and health-related behavior (Aim 4).
