Enterobhsis in an Orphanage

The objectives of this study were to measure dietary fluoride intake in children aged 3-7 years, to correlate dietary fluoride and fluoride content in water for used in schools and to estimate fluoride gained from the daily diet. Fifty food samples were collected in 45 schools under the jurisdietion of the Border Patrol Police Department. The schools were sampled by multiple stratified cluster random sampling. The food samples were weighed, then measured for fluoride content by a micro-diffusion method. Statistical analysis was conducted using the Kruskal-Wallis test. Dietary fluoride in each age group was compared by Student’s t test. Analysis for the relationship between dietary fluoride and fluoride content in water was done using Kendall’s tau-b. Our results showed that mean of dietary fluoride in lunce was 0.08 ± 0.1 ppm. There were no differences when comparing dietary fluoride between different regions of Thailand (p = 0.07). No correlation was found between dietary fluoride and fluoride content in water used in different schools (r = 0.017, p = 0.85). The daily dietary fluoride intake in children aged 3-6 years was 0.002-0.004 mgF/kg BW/day, in children aged 7 years was 0.003-0.004 mgF/kg BW/day in boys and 0.002-0.004 mgF/
