This study evaluates the relationship of goal setting to low-fat vegetable (LV) and fruit/100% juice (FJ) consumption and physical activity (PA) change.
A total of 473 10- to 14-year-old Boy Scouts from Houston took part in a 9-week intervention. A two-group (LV and FJ or PA) intervention design was used with each group serving as the control for the other. Internet-based activities included goal setting at home. Food frequencies measured dietary intake.
Goals attained were not related to LV intake or PA. Immediate posttest FJ consumption increased about 0.7 servings as home FJ availability increased, but social desirability of response appeared to confound reports of FJ intake at posttest 6 months assessment.
Goals attained were not related to LV intake or PA but was related to FJ intake, but only when home FJ availability was high and the relationship was confounded by social desirability of response. Further research is needed with higher quality measures of dietary intake to clarify these relationships.
本研究评估了目标设定与低脂蔬菜（LV）和水果/100%果汁（FJ）消费以及身体活动（PA）变化之间的关系。
休斯顿的 473 名 10 至 14 岁的男童子军参与了为期 9 周的干预。采用两组（LV 和 FJ 或 PA）干预设计，每组均为另一组的对照组。基于互联网的活动包括在家设定目标。食物频率法测量饮食摄入量。
目标的实现与 LV 摄入量或 PA 无关。随着家庭 FJ 供应的增加，即时后测 FJ 消费增加了约 0.7 份，但反应的社会期望似乎混淆了后测 6 个月评估时 FJ 摄入量的报告。
目标的实现与 LV 摄入量或 PA 无关，但与 FJ 摄入量有关，但前提是家庭 FJ 供应充足，并且这种关系受到反应的社会期望的影响。需要使用更高质量的饮食摄入测量方法进一步研究这些关系。
