背景虽然自我监测是改变健康行为的行为方法的核心原则，但临床和公共卫生建议更好地控制体重并不强调体重自我监测。目的：目的是确定更频繁的自我称重是否对体重减轻或预防体重增加产生积极影响。研究方法：这项研究在两个不同的组中检查了自我称重频率和体重之间的横向和纵向关联：1，226名参加体重增加预防试验的成年人和1，800名参加体重减轻试验的成年人。结果如下：尽管样本在体重和基线人口统计学特征方面存在显著差异，但基线称重频率的分布在研究中没有差异。在两组中，基线时更频繁的自我称重与年龄较大、脂肪摄入量较低、白色种族、当前不吸烟状态、更大的节食减肥史和较低的当前体重指数相关。尽管有类似的称重说明，但观察到随时间推移称重频率的差异模式：无论治疗组（对照组或干预组）如何，减肥节食者随时间推移增加体重，而体重增加预防者随时间推移降低对照组的体重，并随时间推移增加干预组的体重。最重要的是，更高的称重频率与24个月的体重减轻或体重增加有关。结论：结果支持每日称重对试图减肥或防止体重增加的个人有价值的观点。每日自我称重应强调在临床和公共卫生信息有关体重控制。在这些情况下，建议对称重频率的影响进行实验研究。
Background. Although self-monitoring is a central tenet Of behavioral approaches to changing health behavior, clinical and public health recommendations for better controlling body weight do not emphasize weight self-monitoring. Purpose: The objective was to determine whether more frequent self-weighing exerts a positive influence on weight loss or weight gain prevention. Methods: This study examined cross-sectional and longitudinal associations between self-weighing frequency and weight in two distinct groups: 1,226 adults who were enrolled in a weight gain prevention trial, and 1,800 adults who were enrolled in a weight loss trial. Results: Although the samples differed significantly in weight and baseline demographic characteristics, the distribution of baseline weighing frequencies did not differ by study. In both groups, more frequent self-weighing at baseline was associated with greater age, lower fat intake, White ethnicity, current nonsmoking status, a greater history of dieting to lose weight, and lower current body mass index. Despite similar weighing instructions, differential patterns of weighing frequency over time were observed: Weight loss dieters increased weighing over time regardless of treatment group (control or intervention), whereas weight gain preventers decreased weighing over time in the control group and increased weighing over time in intervention groups. Most important, higher weighing frequency was associated with greater 24-month weight loss or less weight gain. Conclusions: Results support the idea that daily weighing is valuable to individuals trying to lose weight or prevent weight gain. Daily self weighing should be emphasized in clinical and public health messages about weight control. Experimental studies on the effects of weighing frequency in these contexts are recommended.
