Holidays are challenging for weight control and are consistently associated with weight gain. Managing holiday weight gain may be especially difficult for individuals with higher body weight or a history of overweight/obesity. The current study evaluated how individuals with a history of successful weight loss plan for the holiday season and how the use of weight control strategies was associated with weight change.
A subgroup of participants in the National Weight Control Registry (NWCR) were asked to complete a survey before (November) and after the holidays (January). At pre-holiday, participants reported height, weight, and weight goals for the holiday season (lose, maintain, minimize gains, or gain), and selected the top three weight control strategies they planned to use (from a list of 18). Post-holiday, participants reported weight and how often (frequently, infrequently, or not at all) they used each of the 18 strategies throughout the holidays.
Individuals who completed both surveys were included in the analysis ( = 683; 69% female, 93% white, 54.6 years [SD: 13.2], 26.9 kg/m [SD: 5.5]). Pre-holiday, 64% of participants were currently trying to lose weight. Only 35% of the sample wanted to continue losing weight during the holiday season. The most common strategies individuals planned to use during the holiday season were evidence based (maintaining exercise, monitoring portions, tracking foods, and self-weighing). Participants gained 0.66 kg (SD: 1.85) from pre- to post-holiday and reported using an average of 12/18 strategies. A greater number of strategies were associated with less weight gain ([1, 670] = 4.28, = 0.04). Daily self-weighing ( = 0.03) and prioritizing food choices ( = 0.02) were individually associated with less weight gain.
Participants in the NWCR entered the holiday season with a variety of goals for their weight and used many different strategies to control their weight. Having a wider range of strategies may be helpful to navigate the challenges to weight control during the holidays.
节假日对体重控制而言颇具挑战，且一直与体重增加相关。对于体重较高或有超重/肥胖史的个体来说，控制节假日期间的体重增加可能格外困难。本研究评估了有成功减肥经历的个体在节假日期间如何进行体重管理，以及体重控制策略的使用与体重变化之间的关联。
国家体重控制登记处（NWCR）的一部分参与者被要求在节假日之前（11月）和之后（1月）完成一项调查。在节假日之前，参与者报告身高、体重以及节假日期间的体重目标（减重、维持、尽量减少体重增加或增加体重），并从18种策略列表中选出他们计划使用的前三种体重控制策略。节假日之后，参与者报告体重以及他们在整个节假日期间使用18种策略中每种策略的频率（频繁、不频繁或根本不使用）。
完成两次调查的个体被纳入分析（n = 683；69%为女性，93%为白人，年龄54.6岁[标准差：13.2]，体重指数26.9 kg/m²[标准差：5.5]）。节假日之前，64%的参与者当前正在尝试减肥。样本中只有35%的人希望在节假日期间继续减肥。个体在节假日期间计划使用的最常见策略是基于证据的（保持锻炼、监控食量、记录食物和自我称重）。参与者从节假日之前到之后体重增加了0.66 kg（标准差：1.85），并报告平均使用了18种策略中的12种。更多的策略与更少的体重增加相关（r[1, 670] = 4.28，p = 0.04）。每日自我称重（p = 0.03）和优先选择食物（p = 0.02）分别与更少的体重增加相关。
NWCR的参与者在节假日期间对体重有各种各样的目标，并使用了许多不同的策略来控制体重。拥有更广泛的策略可能有助于应对节假日期间体重控制的挑战。
