简要总结
This is study aims to evaluate the retention of information on oral health and eating habits in children under two years of age. A total of 180 pregnant women aged between twelve and fifty years of age will be selected for this study. Before the randomization process, the literacy in oral health score will be assessed through previously validated instrument BREALD- 30. Participants will be randomly selected according to the value of BREALD-30, categorized as adequate (≥18) and low (<18) in a specific intervention. Interventions occur in written form through an educational brochure or standardized oral, both with information about the feeding practices and oral health in children under two years. The control group will be the implementation of an educational booklet on oral cancer. To evaluate the association between variables pregnant women will respond to a semi-structured form with questions regarding oral health and nutrition, in three different times: before the intervention, 15 minutes after the intervention and 4 weeks after the intervention. Social and economic and demographic data will be evaluated at baseline. The data will be statistically analyzed by Student's t-tests and ANOVA paired, adopting a 5% significance level. In the event of non-normality of the data, the corresponding non-parametric statistical tests will be applied. This study has the hypothesis that the written intervention presents best results in participants with high literacy and the standardized oral with those with low literacy.
详细描述
This study has the objective to verify the relationship between oral health literacy and information retention in health in pregnant women.
A total of 180 pregnant women with age between 12 and 50 years will be recruited to participate in this study. The inclusion criteria are: gestational age up to 32 weeks and who do not have any health problems that would prohibit participation in the study.
In a first moment, the instrument BREALD-30 (Brazilian Rapid Estimate of Adult Literacy in Dentistry), validated for Brazilian portuguese, will be applied to pregnant women who accept to participate voluntarily in the study . This instrument is composed of 30 words related to oral health. These words should be read aloud to the interviewer, each word read correctly, will receive a score equivalent to 1 (one). Thus, the scores can range from 0 (lowest literacy) to 30 (highest literacy). Pregnant women will be classified according to the score achieved in appropriate literacy (equal and more than 18 points) and low literacy (lower than 18 points) according to the value obtained in the lowest quintile. The reading of the instrument's words lasts about two minutes.
After applying the BREALD-30 instrument, the pregnant women will receive a previously tested form with social and economic and demographic information. This information includes maternal age, marital status (categorized into single, married, separated and widow), number of children, occupation and family income. It will be included a list of household items for assessment of social and economic results according to the criteria of the Brazilian Association of Research Companies.
It will be also assessed the degree of knowledge of mothers about feeding habits and oral health of children under two years of age. This step will include the establishment of a list of statements that express opinions with variations in responses: agree, neither agree nor disagree, disagree and do not know, in a Likert scale. The answers are scored 0-1. Scores can vary from 0 to 9. The application form will last about 10 minutes.

Changes in the Knowledge Score
时间窗: The nine statements were applied before the intervention (pre-test), after a 15-minute break, the statements were applied again (post-test). After a 4-week interval, the statement were applied once again.
The knowledge score was assessed by nine statements developed and tested in a pilot study including items related to breastfeeding, supplemental feeding, sugar intake, bottle use, oral hygiene, and use of fluoride toothpaste. These statements were rated on a three-level Likert scale, under the following options: "agree," "neither agree nor disagree," and "disagree," in addition to "I don't know." Each correct answer received score 1 whereas incorrect answers such as "neither agree nor disagree" and "I don't know" were assigned score 0. The final scores ranged from 0 to 9. Higher values indicate better outcomes.
