Problem: Compared with other ethnic groups, Black women are the least likely group to engage in the recommended amount of physical activity. However, few studies have specifically identified or addressed barriers to physical activity in Black college-aged women. Method: This cross-sectional study analyzed data from the 2013 National Health Interview Survey (NHIS) to examine the relationships between LTPA and variables that operationally define social support. A hierarchical logistic regression was used to analyze these relationships and physical activity as well as examine differences in leisure time physical activity (LTPA) in Black college-aged women among different US regions. Results: Controlling for demographic and socioeconomic factors, there was no relationship between social support and LTPA among college-aged Black women. Additionally, the relationship between social support and LTPA did not vary by region. Conclusion: The results of this study indicated there was no relationship between social support and LTPA participation in Black college age women. Health educators may need to develop programs that help young Black women participate in LPTA regardless of social support. More research is necessary to fully understand the interpersonal factors that predict LTPA engagement in young Black female students.
