摘要 通过对60名青少年4次脂肪发育数据的分析,介绍轨迹分析模型在流行病学研究中的应用.结果显示,正常脂肪组、偏高脂肪组、超高脂肪组具有不同的发展趋势.轨迹分析模型在拟合异质性追踪数据方面具有较好的优势. This article introduced the application of trajectory model in epidemiological study on fat development in sixty teenagers.Results showed that fat developing trend on three trajectories-normal fat group,high fat group and very high fat group,with independently different developing trend.Trajectory model seemed a suitable model for fitting the longitudinal data with heterogeneity.
