OBJECTIVE: To identify the factors most strongly associated with sleeping less than 6 consecutive hours at night for children aged 5, 17, and 29 months. DESIGN, SETTING, AND PARTICIPANTS: A randomized survey design used a representative sample of infants born in 1997-1998 in the Canadian province of Quebec. Data were collected by questionnaires and interviews. Interviews were scheduled at home with the mothers. The number of consecutive hours slept at night by 1741 children aged 5, 17, and 29 months was assessed from parental reports. Factors associated with fragmented sleep were investigated for each age in a cross-sectional design. RESULTS: At 5 months of age, 23.5% of children did not sleep 6 consecutive hours. Of the children who did not sleep 6 consecutive hours at night at 5 months or 17 months of age, 32.9% were still not sleeping 6 consecutive hours at night at 29 months of age. The factor most strongly associated with not sleeping at least 6 consecutive hours per night at 5 months of age was feeding the child after an awakening. Parental presence until sleep onset was the factor most strongly associated with not sleeping at least 6 consecutive hours per night at 17 months and 29 months of age. CONCLUSIONS: Sleep consolidation evolves rapidly in early childhood. Parental behaviors at bedtime and in response to a nocturnal awakening are highly associated with the child's sleep consolidation. The effects are probably bidirectional and probably create a long-term problem. Early interventions could possibly break the cycle.
This study assessed the effect of an oral stimulation program on the maturation of sucking skills of preterm infants. Thirty-two preterm infants (13 males, 19 females), appropriate size for gestational age (gestational age at birth 28 wks, SD 1.2wks; birthweight 1002g, SD 251g), were randomly placed into experimental and control groups. The experimental group received a daily 15-minute oral stimulation program, consisting of stroking the peri- and intra-oral structures, for 10 days before the start of oral feedings. Sucking measures were monitored with a specially-designed nipple-bottle apparatus. Results indicate that the experimental group achieved full oral feedings 7 days sooner than the control group, and demonstrated greater overall intake (%), rate of milk transfer (mL/min), and amplitude of the expression component of sucking (mmHg). There was no difference in sucking stage maturation, sucking frequency, and amplitude of the suction component of sucking. Endurance, defined as ability to sustain the same sucking stage, sucking burst duration, and suction and expression amplitudes throughout a feeding session, was not significantly different between the two groups. The stimulation program enhanced the expression component of sucking, resulting in better oral feeding performance.
UNLABELLED: The aim of this study was to evaluate the relationship between nutritive and parafunctional habits and the presence of temporomandibular dysfunction (TMD) in children with primary dentition. METHODS: Ninety nine children, aged 3-5 years, were examined to check for the presence or absence of signs and symptoms of TMD (headache, preauricular pain, earache, masticatory muscle tenderness, deviation on opening, occlusal interference and asymmetric movement of the mandible), oral parafunctions (bruxism, nail biting, finger/thumb sucking, speech alteration, mouth breathing, pacifier and atypical swallowing) and nutritive habits (breast- or bottle-feeding) through interview and clinical examination. The results were submitted to descriptive statistical analysis and Fisher's exact test. RESULTS: The results showed that only atypical swallowing was positively related to TMD (P < 0.0001); other oral parafunctional and nutritive habits were not related to TMD. CONCLUSIONS: It was concluded that parafunctional habits, with the exception of atypical swallowing, and feeding methods were not determinants for the presence of signs and/or symptoms of TMD in the sample of children included in the study.
