Fluoride Intake from Meals Served in Daycare Centres in Municipalities with Different Fluoride Concentrations in the Water Supply

Purpose: The aim of this study was (1) to determine the fluoride content in the meals served to children aged up to 36 months in daycare centres of two municipalities with different levels of fluoride in the water supply, (2) to calculate the mean fluoride ingested daily by the children when consuming those meals and (3) to analyse the contribution of this consumption to the development of dental fluorosisMaterials and Methods: Samples of the meals served to the children were collected during a whole week. The fluoride content of the samples of solid foods and milk was analysed using an ion-specific electrode combined with reference electrode after diffusion facilitated by hexamethyldisiloxane Samples of beverages were buffered with an equal volume of total ionic strength adjustment buffer and analysed using a combined electrode. The results were compared using the Mann Whitney testResults: Mean fluoride contents of the meals were of 0.204 +/- 0 179 and 0.322 +/- 0.242 mu g F/mL (P < 0.05), respectively, in the municipalities with low and adequate fluoride content. Daily fluoride intake in the former was 0.013 +/- 0.003 mg/kg body weight/day and in the latter was 0.012 +/- 0 001 mg/kg body weight/day (P > 0 05)Conclusions: The children were not exposed to dental fluorosis in the daycare centres However, the risk cannot be ignored, considering the meals and the use of fluoridated dentifrices at home may also contribute to fluoride intake.

Brazilian community health agents and qualitative primary healthcare information

The aim of this study was to explore female community health agents’ views about the value of recording qualitative information on contextual health issues they observe during home visits, data that are not officially required to be documented for the Brazilian System of Primary Healthcare Information. Background: The study was conducted in community primary healthcare centres located in the cities of Araçatuba and Coroados (state of São Paulo) and Rio de Janeiro (state of Rio de Janeiro), Brazil. Methods: The design was a qualitative, exploratory study. The purposeful sampling criteria were being female, with a minimum of three years of continuous service in the same location. Data collection with 62 participants was conducted via 11 focus groups (in 2007 and 2008). Audio files were transcribed and submitted to the method of thematic analysis. Four themes guided the analysis: working with qualitative information and undocumented observation; reflecting on qualitative information; integrating/analysing quantitative and qualitative information; and information-sharing with agents and family health teams. In 2010, 25 community health agents verified the final interpretation of the findings. Findings: Participants valued the recording of qualitative, contextual information to expand understanding of primary healthcare issues and as an indicator of clients’ improved health behaviour and health literacy. While participants initiated the recording of additional health information, they generally did not inform the family health team about these findings. They perceived that team members devalued this type of information by considering it a reflection of the clientele’s social conditions or problems beyond the scope of medical concerns. Documentation of qualitative evidence can account for the effectiveness of health education in two ways: by improving preventative care, and by amplifying the voices of underprivileged clients who live in poverty to ensure the most appropriate and best quality primary healthcare for them.
