Past studies have suggested that weight loss history is associated with subsequent weight loss. However, questions remain whether method and amount of weight lost in previous attempts impacts current weight loss efforts. This study utilized data from the Weight Loss Maintenance Trial to examine the association between weight loss history and weight loss outcomes in a diverse sample of high-risk individuals. Multivariate regression analysis was conducted to determine which specific aspects of weight loss history predict change in weight during a 6-month weight loss intervention. Greater weight loss was predicted by fewer previous weight loss attempts with assistance (p = 0.03), absence of previous dietary/herbal weight loss supplement use (p = 0.01), and greater maximum weight loss in previous attempts (p < 0.001). Future interventions may benefit from assessment of weight loss history and tailoring of interventions based on past weight loss behaviors and outcomes.
过去的研究表明,减肥史与随后的减肥有关。然而,之前的减肥尝试中采用的方法和减肥量是否会影响当前的减肥努力仍存在疑问。本研究利用减肥维持试验的数据,在一个高危人群的多样化样本中检查减肥史与减肥结果之间的关系。多元回归分析用于确定减肥史的哪些特定方面可以预测 6 个月减肥干预期间体重的变化。以前减肥尝试次数较少(p=0.03)、以前没有使用过饮食/草药减肥补充剂(p=0.01)和以前减肥尝试中最大减肥量更大(p<0.001)预测减肥效果更好。未来的干预措施可能受益于评估减肥史,并根据过去的减肥行为和结果调整干预措施。
