目的：观察性研究旨在确定参与者完成亚拉巴马大学伯明翰分校EatRight体重管理计划后>= 1年的体重结果和相关饮食摄入模式。研究方法和程序：74名前参与者（64%女性）在参与EatRight后>= 1年完成随访，EatRight促进低能量密度，高复合碳水化合物食物。体重维持的定义是增加< 5% of body weight since completion of the EatRight program and staying below their program entry weight. Those who gained >= 5%的体重，因为完成被归类为gainers.Results：在EatRight，参与者的后续研究失去了平均4.0公斤。平均随访2.2年后，平均体重变化为+0.59 kg（平均BMI为32.5 kg/m2）。78%的参与者体重增加< 5%; 46%的人没有体重反弹或体重继续下降。维持者未经调整的平均摄入量为1608千卡，而增益者的卡路里摄入量为1989千卡。尽管摄入的卡路里略少（调整后的差异为244; p = 0.058），但与体重恢复>= 5%的人相比，保持者摄入的食物量相似，导致能量密度模式较低（p = 0.016）。讨论：我们的研究结果表明，低能量密度的饮食习惯与长期的体重维持有关。那些在EatRight计划后保持体重的人消耗低能量密度的饮食模式，并且比那些恢复体重的人消耗更少的能量密度可能高的食物组。
Objective: Observational study designed to determine weight outcomes and associated dietary intake patterns for a sample of participants >= 1 year after completing the University of Alabama at Birmingham EatRight Weight Management Program.Research Methods and Procedures: Seventy-four former participants (64% women) completed follow-up visits >= 1 year after participating in EatRight, which promotes low-energy density, high-complex carbohydrate foods. Weight maintenance was defined as gaining < 5% of body weight since completion of the EatRight program and staying below their program entry weight. Those who gained >= 5% of their body weight since completion were classified as gainers.Results: During EatRight, participants of the follow-up study lost an average of 4.0 kg. After a mean follow-up time of 2.2 years, the average weight change was +0.59 kg (mean BMI, 32.5 kg/m(2)). Seventy-eight percent of participants gained < 5% of their body weight; 46% had no weight regain or continued weight loss. Unadjusted mean intake for maintainers was 1608 kcal, whereas calorie intake for gainers was 1989 kcal. Despite eating slightly fewer calories (adjusted difference, 244; p = 0.058), maintainers ate a similar amount of food, resulting in a lower energy-density pattern (p = 0.016) compared with those who regained >= 5% of body weight. Gainers also reported consuming larger portions of several food groups.Discussion: Our results indicate that low-energy-density eating habits are associated with long-term weight maintenance. Those who maintain weight after the EatRight program consume a low-energy-density dietary pattern and smaller portions of food groups potentially high in energy density than those who regain weight.
