Objective:To calculate intra-cluster and intra-household design effects and intra-class correlation coefficients for dietary nutrients obtained from a 24 h record-assisted recall.Design:Children were recruited using clustered probability sampling. Randomly selected starting-point addresses were obtained with probability proportional to mesh block size.Setting:Children aged 1–14 years in New Zealand.Subjects:There were 125 children in 50 clusters, giving an average of 2.498 children per cluster… CONTINUE READING
