As part of the Harvard Cancer Prevention Program Project, we sought to address disparities reflected in social class and race/ethnicity by developing and testing a behavioral intervention model that targeted fruit and vegetable consumption, red meat consumption, multivitamin intake, and physical activity in working-class, multiethnic populations.
This paper examined the associations between change in leisure-time physical activity and individual and social contextual factors in participants employed in small businesses (n = 850) at both baseline and at 18-month final.
In bivariate analyses, age, language acculturation, social ties, and workplace social capital were significantly associated with physical activity at final. In multivariable analyses, being younger and having high language acculturation were significantly associated with greater leisure-time physical activity at final; high workplace social capital was significantly associated with a decline in physical activity at final.
These findings have implications for understanding factors that are integral to promoting change in physical activity among working-class, multiethnic populations.
作为哈佛癌症预防计划项目的一部分，我们旨在通过开发和测试一种针对工人阶级多民族人群的水果和蔬菜消费、红肉消费、多种维生素摄入和体育活动的行为干预模型，来解决社会阶层和种族/民族差异问题。
本文研究了在基线和 18 个月终期，在小企业工作的参与者（n=850）中，休闲时间体育活动的变化与个体和社会环境因素之间的关系。
在单变量分析中，年龄、语言文化适应、社会关系和工作场所社会资本与终期的体育活动显著相关。在多变量分析中，年龄较小和语言文化适应度较高与终期的休闲时间体育活动显著相关；高工作场所社会资本与终期体育活动的减少显著相关。
这些发现对于理解促进工人阶级多民族人群体育活动变化的重要因素具有重要意义。
