BACKGROUND: Mood, habits, hormones, and energy expenditure are commanded by the circadian cycle, called the chronotype. The present study sought to analyze the possible association among oral habits and circadian preference (chronotype profile) among children.
METHODS: A retrospective cross-sectional study was conducted at the pediatric dental clinic of a Brazilian federal university, in which 113 parents/guardians of children between 5 and 10 years of age participated. Two data collection instruments were used: 1) a questionnaire, which collected information on infant development, infant feeding, non-nutritive sucking habits, and sociodemographic information; and 2) the Circadian Energy Scale (CIRENS), which was used to measure the children’s chronotype profiles and energy levels. Parents answered the two questionnaires in the waiting room of the university’s pediatric clinic. The Pearson chi-square, Mann Whitney, and Spearman correlation tests were used for statistical analysis.
RESULTS: An association between sucking a pacifier and bottle feeding was observed, in which the children who used a baby bottle also used a pacifier (55.3%; P<0.001). No significant association was found between the chronotype profiles and sucking a pacifier (P=0.360) or finger sucking (P=0.245). However, the total score of the CIRENS was evaluated, and the results showed a higher energy level among children who had received exclusive breastfeeding (P=0.027).
CONCLUSIONS: Our study demonstrated that exclusively breastfed children tend to be more agitated when compared to those who used bottle feeding. Educational policies should be encouraged.
