目的探讨青春期潜在关键期动物和植物蛋白的习惯性摄入与青年期身体组成的关系。设计和方法对DONALD研究的140名女性和122名男性参与者的数据进行多变量回归分析，这些参与者在青春期（女孩9-14岁;男孩10-15岁）有2个3天称重的饮食记录，并在年轻的成年期（18-25岁）进行人体测量。无脂肪质量指数（FFMI）和脂肪质量指数（FMI）估计从四个皮褶。结果在女性中，青春期动物蛋白摄入量与FFMI水平独立相关（p趋势= 0.001），但与FMI无关（p趋势= 0.5）。在能量调整的动物蛋白摄入量三分位数中，FFMI的调整平均值分别为15.3（95%置信区间：15.0，15.5）、15.4（15.1，15.7）、16.2（15.9，16.6）kg/m2。在男性中，仅在根据当前FMI水平调整FFMI后，较高的动物蛋白摄入量与较高的FFMI（ptrend = 0.04）和较低的FMI（ptrend = 0.001）相关，反之亦然。植物蛋白与两性的身体组成无关。结论我们的研究结果表明，青春期动物蛋白质摄入量越高，成年后的去脂质量越高。
Objective To examine the association of habitual animal and plant protein intake during the potentially critical period of puberty with body composition in young adulthood. Design and Methods Multivariable regression analyses were performed on data from 140 female and 122 male participants of the DONALD Study with 2 3-day weighed dietary records during puberty (girls 9-14 years; boys 10-15 years) and anthropometric measurements in young adulthood (18-25 years). Fat-free mass index (FFMI) and fat mass index (FMI) were estimated from four skinfolds. Results In women, a higher pubertal animal protein consumption was independently related to higher levels of FFMI (ptrend = 0.001), but not to FMI (ptrend = 0.5). Adjusted means of FFMI in energy-adjusted tertiles of animal protein intake were 15.3 (95% confidence interval: 15.0, 15.5), 15.4 (15.1, 15.7), 16.2 (15.9, 16.6) kg/m2. In men, a higher animal protein intake was related to a higher FFMI (ptrend = 0.04) and a lower FMI (ptrend = 0.001) only after adjusting FFMI for current FMI levels and vice versa. Plant protein was not associated with body composition among either sex. Conclusions Our results show that a higher pubertal animal protein consumption may yield a higher fat-free mass in young adulthood.
