Overview of Health Disparities Research

In This Section:





Health Disparities Definition

Health disparities are differences in the incidence, prevalence, mortality, and burden of cancer and related adverse health conditions that exist among specific population groups in the United States. These population groups may be characterized by gender, age, ethnicity, education, income, social class, disability, geographic location, or sexual orientation.

Mission

The Division of Cancer Control and Population Sciences (DCCPS) health disparities mission is to monitor the differential burden of cancer among Americans and promote and conduct research that identifies and addresses the economic, social, cultural, psychological, behavioral, and biological mechanisms contributing to these disparities across the cancer control continuum and throughout the human lifespan.

Goals

In response to this challenge, the HDWG will monitor the progress of DCCPS’ efforts to reduce health disparities and will support the following goals:

  • Encourage and improve the development of theory and qualitative and quantitative methods to investigate health disparities.
  • Assess existing data sources and identify additional data needs to expand health disparities research.
  • Describe health disparities in cancer and associated economic, social, cultural, psychological, behavioral, and biological mechanisms over time and across the cancer continuum.
  • Develop efficacious, effective, and culturally relevant interventions to reduce health disparities.
  • Develop strategies for disseminating research knowledge and evidence-based interventions.
  • Disseminate research knowledge and evidence-based interventions.
  • Promote intellectual synergy across the Division’s health disparities efforts.
  • Integrate health disparities activities across the Division.
  • Enhance and strengthen existing networks within the broader cancer control community to support health disparities research.
  • Develop a scientific and conceptual basis of the unequal burden of cancer through seminars, discussions, and reviews.

These goals are directed toward achieving the NCI mission to reduce cancer health disparities.

Major Initiatives

DCCPS has identified a number of critical gaps in research and has worked to focus more research attention to these areas by developing special initiatives. DCCPS also has the responsibility within NCI to monitor the burden of cancer in the United States and to identify health disparities in cancer, and has developed a broad surveillance program to accomplish these goals. Major initiatives and the surveillance program are described in the table. These initiatives are organized by DCCPS Program, and Programs are organized along the cancer control continuum.

Several DCCPS initiatives that focus on health disparities cross cut other NCI priorities. These other priorities are:

  • Quality of cancer care
  • Cancer communications
  • Tobacco
  • Genes and the environment

  • Examines preferred information channels, sources, and information needs of diverse audiences and yields data on perceptions about cancer risks related to health hazards.

2002

Survivorship

Description

Years

Center for Psycho-Oncology Research Specialized Center (P50) Project

  • Conducts biomedical, behavioral, psychological, and social research on the interrelationships among biological processes, cognition, emotion, and physical health among ethno-culturally diverse survivors of breast, prostate, and AIDS-related cervical cancer.
  • Supports 4 R01-level clinical trials to evaluate the efficacy of group-based Cognitive Behavioral Stress Management (CBSM) interventions, and a hormonal treatment to ameliorate adverse consequences of cancer and its treatment among ethno-culturally diverse cancer survivors.
  • Assesses whether CBSM interventions can modulate the output of the sympathetic nervous system, the Hypothalamo-Pituitary-Adrenal axis, and Hypothalamic Pituitary Gonadal hormones; and normalize immunologic status in different populations.
  • Supports pilot studies of CBSM intervention effects in individuals with other cancers, such as malignant melanoma.
  • Develops and tests Spanish translations of interventions for breast and prostate cancer patients.

1999-2003

Minority and Underserved Cancer Survivors Supplement
