to evaluate the agreement between measured height, weight, and body mass index (BMI) during the 22-year follow-up of the 1993 Pelotas Birth Cohort, state of Rio Grande do Sul, Brazil, and self-reported data during the online follow-up of the coortesnaweb.
this was a cross-sectional validation study; agreement was assessed by means of Lin's concordance correlation coefficient for continuous measures and weighted Kappa for nutritional status; Spearman's rank correlation coefficient was used to estimate the correlation between measurements.
a total of 783 participants were included; it could be seen high correlation and high agreement between the measured height (r = 0.966; ρ = 0.966), weight (r = 0.934; ρ = 0.928), and BMI (r = 0.903; ρ = 0.910) and Web-based self-reported data; there was no correlation between mean difference and the time interval between measurements.
using the Internet to collect self-reported anthropometric measurements is as valid as the traditional method.
评估巴西南里奥格兰德州佩洛塔斯 1993 年出生队列在 22 年随访期间测量的身高、体重和体重指数（BMI）与队列网站在线随访期间自我报告数据的一致性。
这是一项横断面验证研究；通过连续测量的林氏一致性相关系数和营养状况的加权 Kappa 评估一致性；Spearman 秩相关系数用于估计测量值之间的相关性。
共纳入 783 名参与者；可以看出，测量身高（r = 0.966；ρ = 0.966）、体重（r = 0.934；ρ = 0.928）和 BMI（r = 0.903；ρ = 0.910）与基于网络的自我报告数据之间存在高度相关性和高度一致性；测量值之间的平均差异与时间间隔之间没有相关性。
使用互联网收集自我报告的人体测量数据与传统方法一样有效。
