Abstract

AIM: To investigate gastric emptying of a mixed solid and liquid meal in normal weight and obese children. METHODS: 114 volunteer children of school age (range 6-11 y) entered the study. Children were considered as being underweight, normal weight, obese, severely obese according to their body mass index (BMI), and were examined using a non-invasive ultrasound method in the morning after an overnight fast period. The examination was always performed in an upright position by the same operator. The half-emptying time and fasting antral area were assessed, and antral area measurements were performed every 30 min for 240 min after meal administration. RESULTS: Five children (4.4%) were underweight, 53 (46.5%) were normal weight, 19 (16.6%) were obese, and 37 (32.5%) were severely obese. The underweight group was not considered for the analysis. No significant difference in t(1/2) was found among the three groups. A positive statistically significant correlation was found between fasting antral area and BMI (r = 0.44; P <0.0001) in all children. The fasting antral area value was 3.5 cm2 (range 1.6-8.1) in normal weight children, 3.6 cm2 (range 1.9-7.7) in obese children, and 3.9 cm2 (range 1.5-10.8) in severely obese children. There was a significant difference between severely obese and normal weight children (P <0.05). No significant difference was found in the gastric emptying between severely obese and obese children, and between severely obese and normal weight ones. CONCLUSION: The difference in fasting antral area in these groups may be considered as an early disturbance. In fact the increased gastric volume could cause a change in the sense of satiety with a consequent increase in the intake of these subjects.
