AbstractWe analyzed the characteristics associated with the growth in length and height of Japanese triplets from birth to 6 years of age and present the growth charts for them. The study included 354 mothers and their 1,061 triplet children, who were born between 1978 and 2006. Data were collected through a mailed questionnaire sent to the mothers asking for information recorded in medical records. For these births, data on triplets' length and height growth, gestational age, sex, parity, and maternal age at delivery were obtained from records in the Maternal and Child Health Handbooks, which is provided by the authorities after a report of pregnancy. Birth length showed the strongest contribution to height of triplets from 1 to 6 years of age. In addition, birthweight was also a significant contributing factor to height from 1 to 3 years of age. Compared to the 50th percentile of the growth standard for the general population of Japan, the length and height deficit of the triplets was approximately 15% at birth (male, –7.0 cm; female, –7.0 cm), decreased within the first year of age, and fluctuated between 2 and 5% until 6 years of age (male, –3.7 cm; female, –3.3 cm). In conclusion, triplets have lower birth length and subsequent height than singletons. In spite of the catch-up growth during the first year of life, they are behind singletons even in mid-childhood. This study provides height growth curves for triplets.
Abstract Background Growth charts are the most commonly used tool for evaluating the development and nutrition of children. The UAE had its first chart produced 30 years ago. Aim The goal of the present study was to derive updated growth charts based on the current UAE child population. A national cross-sectional study involving children in all the seven Emirates that comprise the UAE was undertaken (UAEMCGS 2 study- the United Arab Emirates Multi-Centre Growth Study 2). Subjects and methods Anthropometric measurements (height/length and weight) were made on 20,998 children of both sexes from birth to 18 years of age. Growth charts were constructed using the LMS method and are presented. Results On comparing the 1992 and the 2021 UAE growth charts it was found that there was a significant increase in the height of Emirati children at ages 4 and 5 years in 2021. Conclusion The children’s heights and weights in this study were generally larger than those of the UAE children measured in 1992, and the countries in the WHO study, but were generally smaller than those of USA children as seen from the CDC charts.
"In April 2006, the World Health Organization (WHO) released new international growth charts for children aged 0--59 months. Similar to the 2000 CDC growth charts, these charts describe weight for age, length (or stature) for age, weight for length (or stature), and body mass index for age. Whereas the WHO charts are growth standards, describing the growth of healthy children in optimal conditions, the CDC charts are a growth reference, describing how certain children grew in a particular place and time. However, in practice, clinicians use growth charts as standards rather than references. In
