Previous studies have identified several factors to be associated with physical activity (PA) among African-Americans, e.g., demographic and health-related characteristics. Formative studies suggest a link between sociocultural factors and PA among ethnic minorities; yet, it is unclear whether these factors play a role in PA among African-Americans. This paper explores the association of selected sociocultural characteristics with self-reported PA by gender among African-American adults, taking into account demographic and health-related characteristics.
Data from the baseline survey of a colorectal cancer communication intervention trial were used. Participants included 446 African-American men and women, aged 45-75 years. Self-report data were collected on demographics, health-related characteristics, selected sociocultural constructs (e.g., ethnic identity, religiosity, collectivism, and medical mistrust), and PA. PA was categorized as meeting or not meeting recommended levels; recommended levels were defined as participating in vigorous PA for 20 minutes/day for at least three days/week or moderate PA for 30 minutes/day for at least five days/week or a minimum of 600 MET-minutes/week in at least five days. Chi-square and multivariate logistic regression models were used to characterize the association between the selected sociocultural constructs and PA among men and women, after adjusting for demographic and health-related characteristics.
Most participants reported some PA but only 59% were found to be meeting recommended levels. Univariate analyses revealed that high collectivist attitudes were associated with meeting recommended PA (OR = 1.74), particularly for women (OR = 1.81). In multivariate analyses, high collectivist attitudes were significantly associated with meeting PA recommendations among men (OR = 1.87); while high religiosity and high collectivism were significant among women (OR = 1.87 and 1.85, respectively).
Few of the selected sociocultural characteristics were found to be associated with meeting recommended PA levels. Further study is needed to understand the association of these characteristics with PA among African-Americans.
先前的研究已经确定了一些与非裔美国人的身体活动（PA）相关的因素，例如人口统计学和健康相关特征。形成性研究表明，社会文化因素与少数民族的 PA 之间存在联系；然而，这些因素在非裔美国人的 PA 中是否起作用尚不清楚。本文探讨了在考虑人口统计学和健康相关特征的情况下，选定的社会文化特征与非裔美国成年人按性别报告的 PA 之间的关联。
使用大肠癌传播干预试验基线调查的数据。参与者包括 446 名年龄在 45-75 岁的非裔美国男女。收集了人口统计学、健康相关特征、选定的社会文化结构（如民族认同、宗教信仰、集体主义和医疗不信任）和 PA 的自我报告数据。PA 分为符合或不符合推荐水平；推荐水平定义为每周至少三天每天进行 20 分钟剧烈 PA 或每周至少五天每天进行 30 分钟中度 PA 或每周至少五天进行至少 600 分钟代谢当量的 PA。使用卡方检验和多变量逻辑回归模型，在调整人口统计学和健康相关特征后，描述选定的社会文化结构与男女 PA 之间的关联。
大多数参与者报告了一些 PA，但只有 59%的人达到了推荐水平。单变量分析显示，高集体主义态度与达到推荐 PA 有关（OR=1.74），特别是对女性（OR=1.81）。在多变量分析中，高集体主义态度与男性达到 PA 推荐水平显著相关（OR=1.87）；而高宗教信仰和高集体主义在女性中也显著相关（OR=1.87 和 1.85）。
只有少数选定的社会文化特征与达到推荐的 PA 水平有关。需要进一步研究这些特征与非裔美国人 PA 之间的关系。
