BACKGROUND AND OBJECTIVES Evidence is scarce on the clustering patterns of disordered eating dimensions or symptoms and their effects on future cardiometabolic health. This study examines associations of disordered eating trajectory profiles (from 13 to 21 years), with BMI and related cardiometabolic features at ages 21, 24 and 27. METHODS Participants are from the Epidemiological Health Investigation of Teenagers cohort (Porto, Portugal). At 13, 17 and 21 years, 3 Eating Disorder Inventory subscales were assessed (drive for thinness, bulimia and body dissatisfaction), and a latent class analysis derived trajectory profiles. Associations with BMI and having ≥1 metabolic syndrome feature at 21 (n = 1619), 24 (n = 916) and 27 years (n = 720) were tested using generalized linear models and binary logistic regressions. RESULTS The following 4 profiles were obtained: "higher" levels (highest severity of symptoms at all ages, 16-19%), "increasing" (especially of body concerns, 26-28%), "decreasing" (18-19%), and "lower" (highest proportion of individuals with low/without disordered eating, 35-37%). Compared with the lower levels profile, both sexes with higher and increasing disordered eating presented heightened BMI at 21, 24 and 27 years. Women in the higher levels profile had higher odds of having ≥1 metabolic syndrome feature at 21 and 24 years, while men with higher and increasing disordered eating presented increased odds at 21, 24 and 27 years. CONCLUSIONS Individuals, particularly males, with higher or increasing disordered eating levels from 13 to 21 years of age presented a higher risk of worsened cardiometabolic health up to 6 years later in adulthood.

青春期至成年早期的饮食失调概况和未来的心脏代谢健康。


背景和目标 关于饮食失调维度或症状的聚集模式及其对未来心脏代谢健康的影响的证据很少。本研究检查了饮食失调轨迹概况（13 至 21 岁）与 21、24 和 27 岁时 BMI 和相关心脏代谢特征的关联。方法 参与者来自青少年流行病学健康调查队列（葡萄牙波尔图）。在 13 、 17 和 21 岁时，评估了 3 个饮食失调量表分量表 （瘦、贪食症和身体不满意的驱动力），并进行了潜在类别分析得出的轨迹概况。使用广义线性模型和二元 logistic 回归测试与 BMI 的关联以及在 21 岁 （n = 1619）、24 岁 （n = 916） 和 27 岁 （n = 720） 时具有 ≥1 代谢综合征特征。结果获得了以下 4 个特征：“较高”水平（所有年龄段症状最严重，16-19%）、“增加”（尤其是身体问题，26-28%）、“减少”（18-19%）和“较低”（饮食失调/无饮食失调的个体比例最高，35-37%）。与较低水平相比，饮食失调较高和增加的两性在 21 、 24 和 27 岁时均表现出更高的 BMI。水平较高的女性在 21 岁和 24 岁时出现 ≥1 代谢综合征特征的几率较高，而饮食失调较高且增加的男性在 21 、 24 和 27 岁时出现的几率更高。结论 13 至 21 岁饮食失调水平较高或增加的个体，尤其是男性，在成年后 6 年内心脏代谢健康状况恶化的风险更高。
