As part of the Harvard Cancer Prevention Program Project, we used a social contextual model of health behavior change to test an intervention targeting multiple risk-related behaviors in working-class, multiethnic populations. We examined the relationships between the social contextual factors in our conceptual model and changes in fruit and vegetable consumption from baseline to completion of intervention in health centers and small business studies. We analyzed change in fruit and vegetable consumption, measured at baseline and final assessments by self-report, in 2 randomized controlled prevention trials: 1 in small businesses (n = 974) and 1 in health centers (n = 1954). Stronger social networks, social norms that were more supportive, food sufficiency, and less household crowding were associated with greater change in fruit and vegetable intake. We also observed differences between our intervention sites. Social context can play an important role in promoting changes in fruit and vegetable consumption.
作为哈佛癌症预防项目的一部分，我们运用健康行为改变的社会情境模型，来测试一项针对工人阶级多民族人群多种风险相关行为的干预措施。我们研究了概念模型中的社会情境因素与健康中心及小企业研究中从基线到干预结束时水果和蔬菜消费量变化之间的关系。我们分析了在两项随机对照预防试验中，通过自我报告在基线和最终评估时测量的水果和蔬菜消费量的变化：一项在小企业（n = 974），另一项在健康中心（n = 1954）。更强大的社交网络、更具支持性的社会规范、食物充足以及较少的家庭拥挤与水果和蔬菜摄入量的更大变化相关。我们还观察到干预地点之间的差异。社会情境在促进水果和蔬菜消费变化方面可以发挥重要作用。
