This article characterizes role models identified by emerging/young adults for healthy eating and physical activity (PA), explores variations in reported role models by age, sex and race/ethnicity, and examines dietary/physical activity behaviors in relation to role models. Emerging/young adults (n=397) enrolled in a randomized controlled weight management trial completed assessments at baseline: self-reported role models for healthy eating and PA, Healthy Eating Index, device-measured PA, and demographics. Participants were 78% female, 50% non-White, with mean age 23.3 years, mean BMI 31.1 kg/m². For both healthy eating and PA, the most frequently reported role model was friend (diet: 35%; PA: 39%). Parent was reported second most frequently for healthy eating (21%) and third most frequently for PA (11%). Role models for healthy eating, but not PA, differed by race/ethnicity. Role models did not differ by age or sex. Results may inform future interventions to promote healthy behaviors in emerging adults.

本文描述了新兴/年轻成年人为健康饮食和身体活动 (PA) 确定的榜样，探讨了按年龄、性别和种族/民族报告的榜样的变化，并检查了与榜样相关的饮食/身体活动行为。参加随机对照体重管理试验的新兴/年轻人 ( n = 397) 在基线时完成了评估：健康饮食和 PA、健康饮食指数、设备测量 PA 和人口统计的自我报告角色模型。参与者为 78% 的女性，50% 的非白人，平均年龄 23.3 岁，平均 BMI 31.1 kg/m ². 对于健康饮食和 PA，最常报告的榜样是朋友（饮食：35%；PA：39%）。据报道，父母在健康饮食方面排名第二（21%），在 PA 方面排名第三（11%）。健康饮食的榜样，但不是 PA，因种族/民族而异。榜样不因年龄或性别而异。结果可能会为未来的干预措施提供信息，以促进新兴成年人的健康行为。
