Ambiguity around age ranges for adolescence and adulthood can make the application of age-based nutrition cutoffs confusing. We examined how estimates generated using the age-based anthropometric cutoffs for adolescent girls (10 to <19 y) and women of reproductive age (15-49 y) compared between late-adolescent and young women, and determined how application of both cutoffs affected late-adolescents' estimates. Using cross-sectional data from participants aged 15-23 y in the Pakistan-based Matiari emPowerment and Preconception Supplementation (MaPPS) Trial ( = 25,447), notably large differences in estimates were observed for stunting (30.5% and 7.9% for late-adolescent and young women, respectively; < 0.001) and thinness (9.3% and 30.8%, respectively; < 0.001). When both cutoffs were applied to adolescents' data, estimate differences were maintained. With each year of age, the difference for stunting increased and thinness decreased. Given the discrepancies observed both between and within groups, clarity around application of anthropometric cutoffs for youth (aged 15-24 y) is needed. This trial was registered at clinicaltrials.gov as NCT03287882.
青春期和成年期年龄范围的不明确会使基于年龄的营养临界值的应用变得混乱。我们研究了使用针对青春期女孩（10至<19岁）和育龄妇女（15 - 49岁）的基于年龄的人体测量临界值得出的估计值在青春期晚期和年轻女性之间的比较情况，并确定这两种临界值的应用如何影响青春期晚期人群的估计值。利用巴基斯坦马蒂阿里赋权与孕前补充（MaPPS）试验中15 - 23岁参与者的横断面数据（n = 25,447），观察到发育迟缓（青春期晚期和年轻女性分别为30.5%和7.9%；P < 0.001）和消瘦（分别为9.3%和30.8%；P < 0.001）的估计值存在显著差异。当将这两种临界值应用于青少年数据时，估计值差异依然存在。随着年龄每增加一岁，发育迟缓的差异增大，消瘦的差异减小。鉴于组间和组内均观察到差异，需要明确针对青年（15 - 24岁）的人体测量临界值的应用。该试验在clinicaltrials.gov上注册为NCT03287882。
