ABSTRACT
The aim of this study to assess dental caries status and some growth indices among preschool children of Ulaanbaatar city, Mongolia. The study population consisted of 499 preschool children aged 3-5 years old randomly selected from 6 kindergartens of Ulaanbaatar city. The all children were examined oral examination and body weight and height by anthropometric methods. 1. The caries prevalence of all preschool children was 92.9%. The mean dmft and dmfs score were 8.2±4.8 and 11.7±8.6 of all children, 8.4±4.6 and 12.9±9.1 of 5 years old, 7.8±5.4 and 10.9±9.1 of 4 years old, 8.4±4.7 and 11.3±7.7 of 3 years old, respectively (p<0.01).2. The average body weight and height were 15.8±2.2 кg and 97.7±5.8 cm of 3 years old, 17.2±1.8 kg and 103.4±4.7 cm of 4 years old, 18.5±2.3 kg and 108.1±5.5 cm of 5 years old, respectively (p<0.001).The dental caries prevalence and mean dmft score among preschool children of Ulaanbaatar city were “VERY HIGH” stage, which is determined by criteria WHO. The body height and weight of preschool children of Ulaanbaatar city are increasing year by year. There is not observed significantly the relationship between dental caries status and body growth indices
ABSTRACT
To estimate whether serum leptin has any effects on body composition during the lactational and postnatal periods, we investigated the relationship of serum leptin levels and anthropometric parameters at right after delivery and 16 weeks after delivery in mothers and their infants. Subjects who signed the concent form, participated in this study were recruited from K university hospital. Characteristics of the subjects ( age; 31.0 +/- 4.2 yr, gestation period; 39.5 +/- 1.0 wk) were investigated and anthropometric parameters ( weight, height, body mass index and percent body fat for mothers, and weight, height, head circumference, chest circumference, and Kaup index for infants) were measured. Serum leptin levels of mothers and their infants also measured. Mean maternal serum leptin levels were 9.9 +/- 8.2 ng/ml and 9.1 +/- 7.2 ng/ml at right after delivery and 16 weeks after delivery, respectively showing no significant differences. Mean infant's serum leptin levels at birth ( 1.8 +/- 0.4 ng/ml) were significantly lower than that of at 16 weeks after birth ( 4.2 +/- 0.8 ng/ml)(p < 0.001) . Leptin levels of male infants were not different from those of female infants. There were no correlations between the maternal serum leptin levels with their body weight, percent body fat after delivery. However, significant correlations were found between maternal serum leptin levels with their body weight, BMI, percent body fat at 16 weeks after delivery ( r = 0.80, p < 0.01; r = 0.90, p < 0.001; r = 0.83, p < 0.01, respectively) . There were no cor-relations between the infant's serum leptin levels and their weight, height, head circumference, and chest circumference. No significant relations were also found between maternal serum leptin levels with those of their infants. As a conclusion, maternal serum levels of leptin should be used with a caution to estimate their infant's leptin levels as well as their anthro-pometric parameters. Further researches are needed to examine the relationship among the leptin levels of mother's serum, breast milk, placenta, and infant's serum.
