Scientists at University of Sao Paulo release new data on life sciences in children
2009 AUG 4 - (NewsRx.com) -- Data detailed in 'Fluoride ingestion from food items and dentifrice in 2-6-year-old Brazilian children living in a fluoridated area using a semiquantitative food frequency questionnaire' have been presented. According to recent research from Sao Paulo, Brazil, "The aim of this study was to evaluate the fluoride intake of 2-6-year-old Brazilian children using a semiquantitative food frequency questionnaire (FFQ) which also estimated fluoride intake from dentifrice. The FFQ was previously validated through application to 78 2-6-year-old Brazilian children and then administered to 379 children residing in an optimally fluoridated community in Brazil (Bauru, State of Sao Paulo)." "The FFQ was applied to the parents and used to estimate the food intake of the children. The constituents of the diet were divided into solids, water and other beverages. The fluoride content of the diet items was analyzed with the fluoride electrode. The questionnaire also estimated fluoride intake from dentifrice. The average (±SD) fluoride intake from solids, water, other beverages and dentifrice was 0.008 ±0.005; 0.011 ±0.004; 0.009 ±0.014 and 0.036 ±0.028 mg F/kg body weight/day, respectively, totalizing 0.064 ±0.035 mg F/kg body weight/day. The dentifrice and the diet contributed with 56.3% and 43.7% of the daily fluoride intake, respectively. Among the children evaluated, 31.2% are estimated to have risk to develop dental fluorosis (intake >0.07 mg F/kg body weight/day). The dentifrice was the main source of fluoride intake by the children evaluated. However, the fluoride concentration in food items also significantly contributed to the daily ingestion by 2-6-year-old children," wrote A.P. Miziara and colleagues, University of Sao Paulo. The researchers concluded: "The questionnaire used seems to be a promising alternative to duplicate diet to estimate the fluoride intake at this age range and may have potential to be used in broad epidemiological surveys." Miziara and colleagues published their study in Community Dentistry and Oral Epidemiology (Fluoride ingestion from food items and dentifrice in 2-6-year-old Brazilian children living in a fluoridated area using a semiquantitative food frequency questionnaire. Community Dentistry and Oral Epidemiology, 2009;37(4):305-15). For additional information, contact A.P. Miziara, University of Sao Paulo, Sao Paulo, Brazil.
