We analyzed outcomes from a study that examined social-contextual factors in cancer prevention interventions for working class, multiethnic populations.
Ten community health centers were randomized to intervention or to control. Patients who resided in low-income, multiethnic neighborhoods were eligible; the intervention targeted fruit and vegetable consumption, red meat consumption, multivitamin intake, and physical activity. Outcomes were measured at 8 months.
The intervention led to significant increases in fruit and vegetable consumption and multivitamin intake and reductions in red meat consumption; no change was found in physical activity levels. The intervention effect was not changed when contextual variables that may function as confounders or effect modifiers (e.g., gender, education, race/ethnicity, respondent and parents' country of birth, and poverty status) were included in the analyses.
The intervention led to significant improvements in health behaviors among a working class, multiethnic population, regardless of race/ ethnicity and socioeconomic status. Interventions that respond to the social context of working class individuals across racial/ethnic categories hold promise for improving cancer-related risk behaviors.
我们分析了一项研究的结果，该研究考察了针对工人阶级多民族人群的癌症预防干预措施中的社会背景因素。
将10个社区卫生中心随机分为干预组或对照组。居住在低收入多民族社区的患者符合条件；干预措施针对水果和蔬菜消费、红肉消费、复合维生素摄入和体育活动。在8个月时测量结果。
干预导致水果和蔬菜消费以及复合维生素摄入量显著增加，红肉消费减少；体育活动水平未发现变化。在分析中纳入可能作为混杂因素或效应修饰因素的背景变量（如性别、教育程度、种族/民族、受访者及其父母的出生国家和贫困状况）后，干预效果没有改变。
该干预措施使工人阶级多民族人群的健康行为得到显著改善，无论种族/民族和社会经济地位如何。针对不同种族/民族工人阶级个体的社会背景进行干预，有望改善与癌症相关的风险行为。
