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 1,278 African American adults (age, 46.5 ± 12.6 years; 77% female) and explored potential mediators (stress and depressive symptoms) of those associations.
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.
Greater financial strain was associated with greater odds of insufficient physical activity (P < 0.003) and smoking (P = 0.005) and was positively associated with the total number of cancer risk factors (P < 0.0001). 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.
Future interventions aimed at reducing cancer disparities should focus on African Americans experiencing higher financial strain while addressing their stress and depressive symptoms.
Longitudinal studies are needed to assess the temporal and causal relations between financial strain and modifiable behavioral cancer risk factors among African Americans.
与其他种族群体相比,非裔美国人在癌症行为风险因素的不良后果方面遭受的影响更为严重。最近的研究评估了经济压力如何可能独特地导致人们参与可改变的癌症行为风险因素,但未针对非裔美国人进行此类评估。本研究调查了1278名非裔美国成年人(年龄46.5±12.6岁;77%为女性)中经济压力与可改变的癌症风险因素(吸烟、高危饮酒、超重/肥胖、体育活动不足、水果和蔬菜摄入量不足以及多种风险因素)之间的关联,并探讨了这些关联的潜在中介因素(压力和抑郁症状)。
采用逻辑回归模型来研究经济压力与癌症风险因素之间的关联。分析对年龄、性别、伴侣状况、收入、教育水平和就业状况进行了调整。涉及超重/肥胖状况的分析还控制了水果和蔬菜摄入量以及体育活动。使用非参数自助法程序来评估中介作用。
更大的经济压力与体育活动不足(P<0.003)和吸烟(P = 0.005)的更高几率相关,并且与癌症风险因素总数呈正相关(P<0.0001)。压力和抑郁症状分别对经济压力与身体活动不足和多种风险因素之间的关系产生了显著的间接影响。
未来旨在减少癌症差异的干预措施应关注经济压力较大的非裔美国人,同时解决他们的压力和抑郁症状。
需要进行纵向研究来评估非裔美国人中经济压力与可改变的行为癌症风险因素之间的时间和因果关系。
