| pubmed-article:3606030 | pubmed:abstractText | As part of a mixed cross-sectional and longitudinal survey of Hong Kong children which commenced in 1982, 1048 children (539 boys and 509 girls) with a mean age of 12 years 7 months were measured for standing height and weight. Positive secular trends had occurred in the past two decades when the results of this study were compared with those of Chang and his co-workers who performed a survey in 1961-63. At 12 years old, boys were 6.7 cm taller and 5.7 kg heavier, while girls were 4.2 cm taller and 2.9 kg heavier than subjects in 1961-63. | lld:pubmed |
