Psychosocial and demographic correlates of fruit, juice and vegetable (FJV) consumption were investigated to guide how to increase FJV intake.
Hierarchical multiple regression analysis of FJV consumption on demographics and psychosocial variables.
Houston, Texas, USA.
Boys aged 11-14 years (n = 473).
FJV preference and availability were both significant predictors of FJV consumption, controlling for demographics and clustering of Boy Scout troops. Vegetable self-efficacy was associated with vegetable consumption. The interaction of preference by home availability was a significant predictor of FJV. The interaction of self-efficacy by home availability showed a trend towards significantly predicting vegetable consumption. No significant interactions were found between body mass index and the psychosocial variables.
Findings suggest that future interventions emphasising an increase in preference, availability and efficacy may increase consumption of FJV in similar populations.
研究水果、果汁和蔬菜（FJV）消费的社会心理及人口统计学相关因素，以指导如何增加FJV摄入量。
对FJV消费与人口统计学和社会心理变量进行分层多元回归分析。
美国得克萨斯州休斯顿。
11至14岁男孩（n = 473）。
在控制人口统计学因素和童子军部队聚类的情况下，FJV偏好和可获得性均为FJV消费的显著预测因素。蔬菜自我效能感与蔬菜消费相关。家庭可获得性与偏好的交互作用是FJV的显著预测因素。家庭可获得性与自我效能感的交互作用显示出显著预测蔬菜消费的趋势。体重指数与社会心理变量之间未发现显著交互作用。
研究结果表明，未来强调增加偏好、可获得性和效能感的干预措施可能会增加类似人群中FJV的消费量。
