To examine cross-sectional correlates of current, goal, and dream weight and their prospective associations with weight loss in treatment.
Goal and dream weights, demographic characteristics, and psychosocial factors were assessed by self-report questionnaire in 302 adult women enrolled in a weight loss trial. Height and weight were assessed at baseline, after 8 weeks of active treatment, and at 6- and 18-month follow-up. Regression techniques examined associations among baseline, goal, and dream weights, psychosocial factors, and treatment outcomes.
On average, goal and dream weight losses were unrealistically high (-24% and -30%, respectively). High goals were associated with greater expected effort and greater expected reward but were not associated with psychological distress. Goal and dream weight losses were only weakly associated with behavioral or weight outcomes. An association between higher dream weight losses and greater weight loss at 18 months was the only outcome result to reach statistical significance.
Results suggest that lack of realism in weight loss goals is not important enough to justify counseling people to accept lower weight loss goals when trying to lose weight.
研究当前体重、目标体重和理想体重的横断面相关性及其与减肥治疗中体重减轻的前瞻性关联。
通过自我报告问卷对302名参加减肥试验的成年女性进行目标体重和理想体重、人口统计学特征以及心理社会因素的评估。在基线、积极治疗8周后、6个月和18个月随访时测量身高和体重。采用回归技术研究基线体重、目标体重和理想体重、心理社会因素与治疗结果之间的关联。
平均而言，目标体重和理想体重的减轻幅度高得不切实际（分别为-24%和-30%）。高目标与更大的预期努力和更大的预期回报相关，但与心理困扰无关。目标体重和理想体重的减轻与行为或体重结果仅存在微弱关联。较高的理想体重减轻与18个月时更大的体重减轻之间的关联是唯一达到统计学显著性的结果。
结果表明，减肥目标缺乏现实性的重要性不足以证明在人们试图减肥时建议其接受更低的减肥目标是合理的。
