In the present study, we investigated nutritional status and health-related factors in a multistage cluster sample of 3119 Thai urban and rural children aged 0·5–12·9 years. In a subsample, blood samples were collected for the measurement of Hb, transferrin receptor, vitamin A and vitamin D concentrations. The prevalence of stunting and underweight was higher in rural children than in urban children, whereas the wasting rate was similar in both rural and urban areas. Among children aged 3·0–5·9 years, the prevalence of overweight was significantly higher in urban areas than in rural areas and so was the obesity rate in children aged 6·0–12·9 years. Protein intakes of all age groups were relatively high in both the areas. Intakes of Ca, Fe, Zn and vitamin C were significantly higher in urban areas than in rural areas. The prevalence of anaemia in rural areas was twice as high as that in urban areas, particularly in infants and young children. However, the prevalence of Fe-deficiency anaemia was similar in both urban and rural areas. While the prevalence of vitamin A deficiency (by serum retinol cut-off < 0·7 μmol/l) seemed to be very low, vitamin A insufficiency (by serum retinol cut-off < 1·05 μmol/l) was more prevalent (29·4–31·7 %) in both the areas. The prevalence of vitamin D insufficiency ranged between 27·7 and 45·6 % among the children. The present study indicates that the double burden of malnutrition is still a major public health problem in Thailand. Further studies need to explore the associated risk factors for these nutrient deficiencies. Effective strategies and actions are needed to tackle the nutritional problems in Thai children.

Nutritional Status Of Children

 Background: Family conscious nutrition (Kadarzi) is an Indonesia government program that aims to address the nutrition problem. The family expected to be able to independently giving the best nutrition to improve health. Each Kadarzi indicator has an important role to resolve and prevent the occurrence of utrition problem as indicator of vitamin A supplementation is used to resolve vitamin A deficiency.  Nutrition problems can be seen by using nutritional status. Children under five years are age-prone to experiencenutritional problem such as underweight, stunting, and wasting. Objective: The purpose of this study was to analyze the relationship between the application of Kadarzi behavior with the nutritional status of children under five (WAZ, HAZ, and WHZ). Method: The research was an analytic obsevation research, using cross sectional design. The sample consist of 72 toddlers in Salakkembang Village, Kalidawir Subdistrict, Tulungagung Regency. The data were collected by using weight and height measurement, also Kadarzi bahavior questionnaire. The data were analyzed using Fisher Exact test. Result: The results of the study showed that there was a correlation between Kadarzi behavior with nutitional status of toddlers based on WAZ (p=0.010), and HAZ (p=0.000) but not with WHZ (p=0.368). Conclusion: The better apllication of Kadarzi behavior, the better the nutritional status of toddlers WAZ and HAZ. Mothers should apply Kadarzi behavior to prevent toddlers from nutritional problems. ABSTRAK Latar belakang: Keluarga Sadar Gizi (Kadarzi) merupakan program pemerintah Indonesia yang bertujuan mengatasi masalah gizi. Keluarga diharapkan dapat secara mandiri mewujudkan keadaan gizi yang sebaik-baiknya untuk meningkatkan kesehatan. Setiap indikator Kadarzi memiliki peran penting untuk mengatasi dan mencegah terjadinya masalah gizi seperti indikator pemberian suplemen vitamin A digunakan untuk mengatasi kekurangan vitamin A. Masalah gizi dapat dilihat salah satunya dengan menggunakan status gizi. Balita merupakan usia yang rawan mengalami masalah gizi seperti underweight, stunting, dan wasting.Tujuan: Tujuan dari penelitian ini adalah menganalisis hubungan antara penerapan perilaku Kadarzi dengan status gizi balita (BB/U, TB/U, dan BB/TB).Metode: Penelitian ini merupakan penelitian observasinol analitik, dengan desain penelitian cross sectional. Sampel terdiri dari 72 balita di Desa Salakkembang, Kecamatan Kalidawir, Kabupaten Tulungagung. Pengumpulan data menggunakan penimbangan berat badan, tinggi badan, dan kuesioner perilaku Kadarzi. Data dianalisis menggunakan Fisher Exact test. Hasil: Hasil dari penelitian menunjukkan terhadap hubungan antara perilaku Kadarzi dengan status gizi balita BB/U (p=0,010) dan TB/U (p=0,000) namun tidak dengan BB/TB (p=0,368).Kesimpulan: Semakin baik penerapan perilaku Kadarzi maka semakin baik status gizi balita BB/U dan TB/U. Ibu dan seluruh anggota keluarga seharusnya menerapkan perilaku Kadarzi agar balita terhindar dari masalah gizi.

1. Changes in total retinol-binding protein (RBP), the holoprotein (holoRBP) and prealbumin (PA) concentrations have been monitored in plasma of thirty protein- and vitamin A-deficient preschool children from within a few hours up to 7 weeks after treatment with retinol and a good-quality protein diet.2. The children were classified into groups according to nutritional status as having either kwashiorkor, marasmus-kwashiorkor or marasmus, and given formula diets whose protein and energy contents increased stepwise from 1 g and 105 kJ/kg body-weight respectively up to 4 g and 733 kJ/kg body-weight after 4 weeks. Retinol was administered in the forms of retinyl palmitate either orally or intramuscularly.3. PA and total RBP were determined by electroimmunoassay procedures and the holoRBP by its fluorescence after separation from other plasma proteins.4. RBP in plasma of the vitamin A-deficient child is largely denatured and incapable of binding administered retinol, which must first be taken up by the liver before native holoRBP is released. An increased pool of native apoprotein accumulates in the liver during vitamin A deficiency which is released into plasma quickly after retinol uptake to form peak concentrations of total and holoRBP approximately 3 h after dosing intramuscularly and 6 h orally.5. The accumulated pool of RBP was highest in livers from the marasmus group and lowest in those from the kwashiorkor group, reflecting their relative capacities to synthesize plasma proteins.6. The mean plasma concentrations of total and holoRBP for the various groups were minimal 24–48 h after dosing with retinol and then improved almost linearly over the following week.7. Mean plasma PA concentrations of the various groups on admission were also in order of the severity of their malnutrition. There was little or no change in this protein concentration over the first 24 h after dosing with retinol, but thereafter the mean values rose almost linearly over 2 weeks. Albumin on the other hand changed little during the first week. The results show that PA is the more sensitive measurement of protein nutritional status.
