To examine the demographic and psychosocial factors associated with increased fruit and vegetable (FV) consumption among smokers residing in public housing.
Cluster randomized trial of 20 public housing developments (HDs). Ten housing developments were randomly assigned to a FV intervention and 10 to a smoking cessation intervention.
Change in daily FV intake over the past 7 days at 8 weeks postbaseline.
Above the effect of treatment, baseline confidence for vegetable consumption (model coefficient = 0.19, SE = 0.07, p = .01), decreased barriers (model coefficient = -0.12, SE = 0.04, p = .002) and increased agency (model coefficient = 0.08, SE = 0.04, p = .03) were significantly associated with week 8 FV consumption.
Although the intervention produced significant change in FV consumption, the majority of individual psychosocial factors were not associated with this change. Future studies examining the dynamic interaction between interventions and individual, social, and environmental factors are needed to more fully explain dietary change among public housing residents.
研究公共住房吸烟者中与增加水果和蔬菜（FV）摄入量相关的人口统计学和社会心理因素。
对20个公共住房开发区（HDs）进行整群随机试验。10个住房开发区被随机分配到FV干预组，10个被分配到戒烟干预组。
基线后8周时过去7天每日FV摄入量的变化。
除治疗效果外，蔬菜消费的基线信心（模型系数=0.19，标准误=0.07，p=0.01）、减少的障碍（模型系数=-0.12，标准误=0.04，p=0.002）和增强的能动性（模型系数=0.08，标准误=0.04，p=0.03）与第8周的FV消费显著相关。
虽然干预使FV消费产生了显著变化，但大多数个体社会心理因素与这种变化无关。未来需要研究干预措施与个体、社会和环境因素之间的动态相互作用，以更全面地解释公共住房居民的饮食变化。
