Objective : Identify the difference of the nutritional status of Thai children from birth to 24 months of age using the national
and international growth charts.
Material and Method: The analytic sample was of 4,224 children from the Prospective Cohort Study of Thai Children
(PCTC). Age-specific prevalence of malnutrition was estimated using the NCHS, WHO, and Thai growth charts.
Results : Rapid growth faltering was found in both genders during the first two years, regardless of the reference, but
the Thai charts reflected better Thai children. When using the Thai and NCHS charts, a steep fluctuation was observed in
infancy, although the prevalence of wasting, underweight, and overweight between the references became narrower at 24
months. Meanwhile, the WHO standards identified a higher number of stunted children and showed a linear increasing
trend of overweight with age, compared to the Thai reference.
Conclusion : Although the Thai growth charts better reflect the Thai children, in consideration of a double burden of stunting
and overweight in Thailand, the WHO standards can be used to identify Thai children at risk of stunting and overweight in
the first two years of life.
