Updated J apanese growth references for infants and preschool children, based on historical, ethnic and environmental characteristics

View Article: PubMed Central

ABSTRACT

Aim: To provide updated growth references for Japanese children from birth to 6 years of age, for use in both growth monitoring and child care.

Methods: We analysed data from two national representative surveys that provided cross‐sectional data on 3000 areas in the 2005 national census and longitudinal data from 136 hospitals. Growth references for length/height, weight, head circumference and chest circumference were constructed using the lambda‐mu‐sigma (LMS) method, with estimates of the L,M and S parameters. These updated values were then compared with growth references published by the World Health Organization.

Results: The 3rd, 50th and 97th smoothed percentile values of length/height, weight, head circumference and chest circumference for boys and girls from birth to 6 years are presented. The comparisons show some large differences in median measurements between the charts.

Conclusion: Our growth references are based on a current, nationally representative sample of Japanese children. The results provide deep insight into child growth from a historical, ethnic and environmental point of view.

apa12587-fig-0003: Comparison of selected percentiles for weight references Japan 2010 reference in the present study, WHO 2006 reference 16. The three lines correspond to the 3rd, 50th and 97th percentile values from the lower to the upper lines.

Mentions: Figure 3 compares the third, 50th and 97th percentile curves between the WHO 2006 reference and the present study. The WHO 2006 curves are based on the values appearing in the tables of weight for age in weeks. At birth, the Japanese reference was 0.4 kg lower in both boys and girls. At 1 week of age, the Japanese reference was 0.6 kg lower in boys and 0.7 kg lower in girls. The Japanese reference was 0.3 kg lower at 4 weeks of age and 0.2 kg lower at 8 weeks of age in both boys and girls.
