Abstract

The aim of the present study was to analyze the intentions and knowledge of mothers in the postpartum period regarding the feeding habits and oral health of their children. A cross-sectional study was conducted involving 286 mothers at a teaching hospital in Southern Brazil. The variables of interest were collected using a semi-structured questionnaire. Knowledge scores were analyzed numerically and dichotomized as adequate (score: >5) or poor (score: ≤5). Bivariate and multivariate Poisson regression analyses were performed and score ratios (SR) with respective confidence intervals (CI) were calculated. Most respondents were less than 25 years of age (55.6%), first-time mothers (56.4%) and demonstrated positive intentions regarding the majority of the aspects addressed. However, 65.4% of the sample demonstrated poor knowledge. Younger mothers, those with a lower income, those with less schooling, first-timers and those who reported intending to use sugar demonstrated less knowledge. Gathering information from the internet was associated with higher knowledge. The multivariate model revealed significant associations with having a university education (SR=1.23; CI: 1.12 to 1.35), having a high school education (SR=1.10; CI: 1.03 to 1.19), gathering information from the internet (SR=1.18; CI: 1.07 to 1.30), having given birth more than once (SR=1.13; CI: 1.06 to 1.21) and intending not to use sugar (SR=1.14; CI: 1.03 to 1.26). Schooling, number of child births, means of information and the use of sugar were independently associated with the knowledge score. There is a need to provide oral health education for women during the postpartum period in order to benefit oral health for both the mother and the baby.
