Rates of obesity and overweight in the U.S. are increasing rapidly, while current weight control programs remain relatively ineffective. A primary' prevention approach, which targets individuals at risk for weight gain, may prove more efficacious. Such prevention programs should include assessment of long-term outcome and, to maximize participation rates, should be tailored to appeal to the at-risk population. The aim of the present study is, therefore, to test the long-term efficacy of two programs for primary prevention of weight gain in normal-weight women aged 25-34, a group at high risk for weight gain, and to assess participation rates in these two treatment formats. Subjects (N=300) responding to recruitment materials will be randomly assigned to 1 of 3 treatment formats (group meetings designed to appeal to women aged 25- 34, correspondence course, no-treatment control). Subjects in the group meeting format and the correspondence course will participate in 24- month behavioral weight gain prevention programs. For all three formats, weight will be assessed at 0, 12, 24 and 36 months. Participation rates for the two active treatments will be assessed at 12 and 24 months. Primary' outcome variables will be the proportions of subjects in each format maintaining baseline weight at 36 months and participation rates for the two active treatments at 12 and 24 months. The proposed research is important because it explicitly focuses on primary prevention of weight gain in individuals at risk for future weight gain. It seeks to determine the long-term efficacy of two such programs and to determine the treatment format which produces the largest participation rates. If efficacious, the interventions can be adapted for use in clinical settings. Determination of participation rates can also be used to increase the population outreach of weight gain prevention programs.

美国的肥胖率和超重率正在迅速上升，而目前的体重控制计划仍然相对无效。针对有体重增加风险的个体的初级预防方法可能更有效。这种预防方案应包括对长期结果的评估，并且为了最大限度地提高参与率，应针对高危人群进行调整。因此，本研究的目的是测试25-34岁正常体重女性（体重增加的高风险群体）体重增加的两个初级预防方案的长期疗效，并评估这两种治疗形式的参与率。响应招聘材料的受试者（N=300）将被随机分配到三种治疗形式中的一种（旨在吸引25- 34岁女性的小组会议、函授课程、无治疗对照组）。参加小组会议和函授课程的受试者将参加为期24个月的行为体重增加预防计划。对于所有三种格式，将在0、12、24和36个月时评估体重。两种积极治疗的参与率将在12个月和24个月时进行评估。主要结果变量将是每种形式的受试者在36个月时保持基线体重的比例，以及两种积极治疗在12个月和24个月时的参与率。这项提议的研究很重要，因为它明确地关注了未来有体重增加风险的个体体重增加的初级预防。它试图确定这两个项目的长期效果，并确定产生最大参与率的治疗形式。如果有效，干预措施可适用于临床环境。参与率的确定也可以用来增加预防体重增加项目的人口覆盖面。
