利用维持和可视化 BMI ≥95% 变异性的方法和图表工具来确定 BMI 轨迹，并研究这些轨迹上早期社会人口风险、婴儿生长和喂养模式以及母亲体重状况的个体差异。参与者包括来自家庭生活项目（纵向出生队列）的 1,041 个主要是农村贫困家庭。青少年人体测量在 2 个月至 12 岁之间进行了 8 次测量； 2 个月时，母亲报告了社会人口统计数据、青少年出生体重、婴儿喂养以及自我报告的儿童体重和身高（2 个月和 12 岁时）。 6 个月时，母亲报告母乳喂养。 2岁时测量了母亲的体重和身高。确定了三种 BMI 轨迹：“保持不超重”、“发展为肥胖”和“发展为严重肥胖”。与非超重轨迹相比，轨迹较重的儿童母乳喂养时间较短，并且在所有评估中都有较重的母亲。具有“发展性肥胖”轨迹的儿童出生时体重并不比非超重轨迹的儿童重，但他们在婴儿期的体重身长百分位数变化更大；此外，他们的母亲在 2 个月至 12 岁之间的 BMI 变化最大。具有“严重肥胖”轨迹的儿童出生时体重较重，并且更有可能在婴儿期体重增加并较早喂养固体食物。使用明智的分析和制图方法，我们描述了贫困农村青年的不同样本中的生长模式，并确定了肥胖和严重肥胖轨迹的早期预测因子。敦促研究人员在未来的工作中考虑这些方法，并重点关注确定肥胖和严重肥胖青少年的保护因素。
To identify BMI trajectories utilizing methods and graphing tools that maintain and visualize variability of BMIs ≥95th percentile, and to investigate individual differences in early sociodemographic risk, infant growth and feeding patterns, and maternal weight status on these trajectories. Participants included 1,041 predominantly rural, poor families from the Family Life Project, a longitudinal birth cohort. Youth anthropometrics were measured 8 times between ages 2 months and 12 years; at 2 months, mothers reported sociodemographics, youth birthweight, infant feeding, and self-reported child weight and height (at 2 months and 12 y). At 6 months, mothers reported breastfeeding. At 2 years maternal weight and height were measured. Three BMI trajectories were identified: “maintained non-overweight,” “developed obesity,” and “developed severe obesity.” Compared with the non-overweight trajectory, the children with heavier trajectories were breastfed for a shorter duration and had heavier mothers at all assessments. The children with “developed obesity” trajectory were not heavier at birth than those with non-overweight trajectory, yet, they displayed greater change in weight-for-length percentile during infancy; additionally, their mothers had the highest change in BMIs between 2 months and 12y. Children with the “developed severe obesity” trajectory was heavier at birth, and more likely to be heavy during infancy and fed solid foods early. Using informed analytical and graphing approaches, we described patterns of growth, and identified early predictors of obesity and severe obesity trajectories among a diverse sample of poor, rural youth. Researchers are urged to consider these approaches in future work, and to focus on identifying protective factors in youth with obesity and severe obesity.
