Abstract
BACKGROUND: To develop new growth references for height, weight, and body mass index (BMI) for children aged 0-5 years in the Taiwan Birth Cohort Study (TBCS) and to compare these references with both 1997 Taiwan references and World Health Organization (WHO) standards. METHODS: Data were obtained from the TBCS of a nationally representative sample of 24,200 children. A total of 18,466 children completed the baseline survey at 6 months of age and three follow-up surveys at 18 months, 3 years, and 5.5 years of age. The modified LMS method was used to construct percentile curves by sex, including length/height for age, weight for age, and BMI for age. RESULTS: TBCS children of both sexes were shorter and lighter at birth compared with 1997 Taiwan references and WHO standards. The growth patterns of TBCS children were close to those of the 1997 Taiwan references after 6 months of age. Compared with WHO standards, however, TBCS children were heavier after 6 months of age. CONCLUSION: This study has developed TBCS references to monitor the growth of children in Taiwan, whose weight growth patterns differed from those "prescribed" by WHO standards.
