This chapter presents an illustration of the complexities involved in studying ethnic and racial influences on psychosocial processes and how they are intimately tied to physical outcomes in later life. It focuses on psychology as a discipline, minority aging research during the last several decades has revealed the need for multidisciplinary and intersectional conceptual and research approaches. The chapter also focuses on the age, gender, socioeconomic, cultural, and racial and ethnic graded influences on life course development that eventuate in unequal burdens of psychological and physical health morbidity and mortality for certain groups in late life. No section on psychology could be complete without a discussion of religion and spirituality among racial and ethnic minorities. Generational processes are clearly implicated in ideas about the cyclical nature of poverty and health behaviors that are intricately linked with environmental factors and social influence.

This chapter presents an integrative approach to the psychological study of minority populations and the reduction of health disparities through positive nonmaterial resources. It provides a brief introduction to positive psychology and to the concept of early life origins of disease, highlighting the value of integrating these seemingly disparate literatures as a lens for studying health and broader aging processes among minority populations. Minority status whether based on ethnicity, gender, socioeconomic status (SES), citizenship, religion, or other factors is a robust determinant of health, well-being, and success across the life span and intergenerationally. Positive psychology is relevant to health and development particularly physiological and psychological adaptation to stress across the life span, and even across multiple generations among humans in general and among minority populations in particular. Health inequalities are the result of unique challenges to successful psychological and physiological adaptation faced by minority group members.

This chapter provides selective review of research on religion and spirituality across three groups of racial and ethnic minority older adults African American, Asian American, and Hispanic/Latino. It discusses major denomination and faith traditions, as well as information about types and patterns of participation and their sociodemographic correlates. The chapter examines informal social support provisions within faith communities and the types of assistance exchanged. It also examines associations between religion, spirituality and physical/mental health, and psychological well-being. Religion and spirituality, through a variety of psychosocial mechanisms and pathways are thought to have largely beneficial impacts on physical and mental hea.

Improved nutritional status is an important component of efforts to improve the health of older adults, whose ability to consume a healthy diet is affected by comorbidities and behavioral, cognitive, and psychological factors. In addition to genetics and nutrition intake, nutritional status of the elderly could be affected by socioeconomic factors, such as education and income levels, and environmental factors, such as proximity to stores and transportation, that can affect food variety and availability. Nutrition and aging are connected inseparably because eating patterns affect progress of many chronic and degenerative diseases associated with aging. Anthropometric measurements are often used for nutritional assessment of older adults and are reliable across ethnicities. The Mini-Nutritional Assessment (MNA) tool was developed to evaluate the risk of malnutrition among frail older adults. Dietary patterns may better capture the multifaceted effects of diet on body composition than individual nutrients or foods.
