OBJECTIVE To understand preferences for features of weight loss programs among adults with or at risk of type 2 diabetes in the U.K. RESEARCH DESIGN AND METHODS We conducted a discrete choice experiment with 3,960 U.K. adults living with overweight (n = 675 with type 2 diabetes). Preferences for seven characteristics of weight loss programs were analyzed. Simulations from choice models using the experimental data predicted uptake of available weight loss programs. Patient groups comprising those who have experience with weight loss programs, including from minority communities, informed the experimental design. RESULTS Preferences did not differ between individuals with and without type 2 diabetes. Preferences were strongest for type of diet. Healthy eating was most preferred relative to total diet replacement (odds ratio [OR] 2.24; 95% CI 2.04–2.44). Individual interventions were more popular than group interventions (OR 1.40; 95% CI 1.34–1.47). Participants preferred programs offering weight loss of 10–15 kg (OR 1.37; 95% CI 1.28–1.47) to those offering loss of 2–4 kg. Online content was preferred over in-person contact (OR 1.24; 95% CI 1.18–1.30). There were few differences in preferences by gender or ethnicity, although weight loss was more important to women than to men, and individuals from ethnic minority populations identified more with programs where others shared their characteristics. Modeling suggested that tailoring programs to individual preferences could increase participation by ∼17 percentage points (68% in relative terms). CONCLUSIONS Offering a range of weight loss programs targeting the preferred attributes of different patient groups could potentially encourage more people to participate in weight loss programs and support those living with overweight to reduce their weight.

确定患有 2 型糖尿病或有 2 型糖尿病风险的成年人的减肥计划的首选特征：针对英国 3,960 名成年人的离散选择实验

目的 了解英国患有 2 型糖尿病或有患 2 型糖尿病风险的成年人对减肥计划特征的偏好 研究设计和方法 我们对 3,960 名超重的英国成年人（n = 675 患有 2 型糖尿病）进行了离散选择实验。分析了对减肥计划七个特征的偏好。使用实验数据对选择模型进行的模拟预测了可用减肥计划的采用情况。由具有减肥计划经验的患者组成的患者群体（包括来自少数民族社区的患者）为实验设计提供了信息。结果 患有和未患有 2 型糖尿病的个体之间的偏好没有差异。对饮食类型的偏好最强。相对于总饮食替代，健康饮食是最受青睐的（比值比 [OR] 2.24；95% CI 2.04–2.44）。个体干预比团体干预更受欢迎（OR 1.40；95% CI 1.34-1.47）。与那些减重 2-4 公斤的项目相比，参与者更喜欢减重 10-15 公斤（OR 1.37；95% CI 1.28-1.47）的项目。在线内容优于面对面接触（OR 1.24；95% CI 1.18–1.30）。尽管减肥对女性比男性更重要，但不同性别或种族的偏好几乎没有差异，而且少数民族人群更认同其他人具有相同特征的项目。模型表明，根据个人偏好定制计划可以将参与度提高约 17 个百分点（相对而言为 68%）。结论 针对不同患者群体的偏好特征提供一系列减肥计划可能会鼓励更多的人参与减肥计划，并支持超重者减轻体重。
