Disparities in Obesity, Physical Activity Rates, and Breast Cancer Survival.

Area of Science:

• Public Health
• Cancer Disparities
• Health Behavior

Background:

• African-American (AA) women experience significantly higher breast cancer (BCa) mortality rates compared to non-Hispanic white (NHW) women, representing a major US health disparity.
• While tumor biology is often cited, lifestyle factors like obesity, prevalent in AA communities, also significantly impact BCa progression and recurrence.
• Limited access to care, socioeconomic status, and education levels in AA communities contribute to sedentary lifestyles and reduced healthy food options.

Purpose of the Study:

• To explore the utility of the Social Ecological Model (SEM) as a framework for developing interventions to reduce obesity among AA women.
• To identify how SEM-based interventions can positively modify lifestyle behaviors to mitigate BCa risk, progression, and recurrence in AA women.

Main Methods:

• Conceptual framework analysis using the Social Ecological Model (SEM).
• Review of factors contributing to obesity and BCa disparities in AA communities.

Main Results:

• The SEM, encompassing intrapersonal, interpersonal, organizational, and community/institutional factors, offers a comprehensive approach to behavior modification.
• Interventions based on the SEM are more effective when considering the participant's environmental context.

Conclusions:

• Implementing SEM-based interventions in AA communities can effectively modify lifestyle behaviors.
• These lifestyle modifications hold significant potential for reducing breast cancer risk, progression, and recurrence among AA women.
