African Americans experience a high burden of chronic diseases and cancers that are prevented and ameliorated with physical activity (PA) and fruit and vegetable (FV) intake. The purpose of this study is to identify individual, social, and neighborhood variables associated with African Americans attaining high levels of both behaviors.
This study is a cross-sectional analysis.
Cohort of African Americans adults recruited from black churches in the Greater Houston area.
Self-administered questionnaires collected in 2012 assessed correlates and behavioral outcome variables (PA and FV consumption). A combined 4-category behavioral outcome was created: high PA/high FV, low PA/high FV, high PA/low FV, and low PA/low FV.
Standard and stepwise multinomial logistic regression examined the association between the various variables and the behavioral outcome.
This sample (n = 1009) had a mean age of 49 years, was mostly female, and obese. Compared to the low PA/low FV intake group, the high PA/high FV intake group had significantly lower odds of individual-level variables (worrying about getting cancer, perceived stress, loneliness, and financial strain) and higher odds of social-level variables (social status, social cohesion, social organization involvement, and social norms). Only social-level variables remained significantly associated with higher odds of high PA/high FV intake in stepwise regression.
These findings indicate that social influences may be most critical for high PA and FV intake in African Americans adults.
非裔美国人承受着很高的慢性病和癌症负担,而体育活动(PA)以及水果和蔬菜(FV)的摄入可以预防和改善这些疾病。本研究的目的是确定与非裔美国人同时达到高水平这两种行为相关的个人、社会和社区变量。
本研究为横断面分析。
从大休斯顿地区的黑人教堂招募的非裔美国成年人队列。
2012年收集的自填式问卷评估了相关因素和行为结果变量(PA和FV消费)。创建了一个包含4类的综合行为结果:高PA/高FV、低PA/高FV、高PA/低FV和低PA/低FV。
标准和逐步多项逻辑回归检验了各种变量与行为结果之间的关联。
该样本(n = 1009)的平均年龄为49岁,以女性为主,且存在肥胖问题。与低PA/低FV摄入组相比,高PA/高FV摄入组在个人层面变量(担心患癌症、感知压力、孤独和经济压力)上的几率显著较低,而在社会层面变量(社会地位、社会凝聚力、社会组织参与度和社会规范)上的几率较高。在逐步回归中,只有社会层面变量与高PA/高FV摄入的较高几率仍显著相关。
这些发现表明,社会影响可能对非裔美国成年人的高PA和FV摄入最为关键。
