Financial Strain and Cancer Risk Behaviors among African Americans

Abstract

Background African Americans suffer disproportionately from the adverse consequences of behavioral risk factors for cancer relative to other ethnic groups. Recent studies have assessed how financial strain might uniquely contribute to engagement in modifiable behavioral risk factors for cancer, but not among African Americans. The current study examined associations between financial strain and modifiable cancer risk factors (smoking, at-risk alcohol use, overweight/obesity, insufficient physical activity, inadequate fruit and vegetable intake, and multiple risk factors) among 1278 African American adults (age=46.5±12.6, 77% female) and explored potential mediators (stress and depressive symptoms) of those associations. Methods Logistic regression models were used to examine associations between financial strain and cancer risk factors. Analyses were adjusted for age, sex, partner status, income, educational level, and employment status. Analyses involving overweight/obesity status additionally controlled for fruit and vegetable intake and physical activity. Nonparametric bootstrapping procedures were used to assess mediation. Results Greater financial strain was associated with greater odds of insufficient physical activity (p<.003) and smoking (p=.005) and was positively associated with the total number of cancer risk factors (p<.0001). There was a significant indirect effect of both stress and depressive symptoms on the relations of financial strain with physical inactivity and multiple risk factors, respectively. Conclusions Future interventions aimed at reducing cancer disparities should focus on African Americans experiencing higher financial strain while addressing their stress and depressive symptoms. Impact Longitudinal studies are needed to assess the temporal and causal relations between financial strain and modifiable behavioral cancer risk factors among African Americans.

HPV Awareness, Knowledge and Attitudes among Older African-American Women

“…Details about this study have been previously published. 24-31 Participants (N = 1501) were recruited into the cohort study from a large, Methodist church in Houston, Texas, via televised media and in-person solicitation. Participants were required to be ≥18 years old, residents of the Houston area with a functional telephone number, able to read and speak English, and church attendees.…”

A comparative effectiveness education trial for lifestyle health behavior change in African Americans

“…Another possible explanation for the lack of significant change in FV intake is because of the high unemployment rates and low incomes of our study population. Financial strain has been associated with cancer risk behaviors among African Americans [43].…”

The Built Food Environment and Dietary Intake among African-American Adults

“…This site was selected based on a successful multi-year partnership with church leadership and parishioners within which several previous studies have been conducted. 32-38 Individuals who participated in our previous studies and who consented to be contacted for future studies were sent a flyer about the present data collection via email. The email announcement indicated we were engaging in limited recruitment for a new study focused broadly on stress and health behaviors among African-American adults.…”
