South East Asian Nutrition Surveys II (SEANUTS II) Thailand: triple burden of malnutrition among Thai children aged 6 months to 12 years

Abstract

Abstract Objective: This study assessed nutritional status among Thai children using anthropometry, dietary intakes and micronutrient status. Design: Cross-sectional survey with multi-stage cluster sampling. Body weight and height were measured in all children. Dietary intakes were assessed using 24-h dietary recall. Biochemical assessment was performed in one-third of the children. Setting: The study was conducted in Thailand’s four geographical regions and Bangkok. Participants: 3478 Thai children aged 0·5–12·9 years. Results: Stunting showed a downward trend by age group and was most prevalent among infants and toddlers. Overweight and obesity showed a significant upward trend by age group, location and sex and were highest among children aged 7–12·9 years. Risks of inadequate micronutrient intakes (Ca, Fe, Zn, vitamins A, C and D) were high (53·2–93·6 %). Prevalence of Zn and mild vitamin A deficiencies were low; vitamin D and B12 deficiencies were nil. Vitamin D insufficiency was significantly higher in the urban area and among girls. Anaemia was very high in infants and toddlers (56·6 and 35·2 %) but showed a significant downward trend by age group. There was an overall high prevalence of Fe deficiency (25 %) v. Fe deficiency anaemia (4·2 %) among children aged 4–12·9 years old. Conclusions: The high prevalence of stunting and anaemia among children aged 0·5–3·9 years and overweight and obesity among children aged 7–12·9 years requires continued attention. While prevalence of biochemical micronutrient deficiencies was not high (except for Fe), high prevalence of dietary inadequacies for several micronutrients warrants further in-depth investigations.
