Is motor competence associated with the risk of central obesity in preschoolers?

OBJECTIVES: To investigate the association between motor competence (MC) and central obesity in preschool children. METHODS: The sample comprised of 472 children aged 3 to 5 years (4.58 ± 0.70 years, 248 boys) from Recife, Brazil. MC was assessed using the Test of Gross Motor Development-2. Waist-to-height ratio (WHtR) was calculated and a cutoff of 0.5 was used to define central obesity. Logistic regression was used to examine the association between MC and WHtR ≥ 0.5. RESULTS: The prevalence of central obesity (WHtR) was 54.0% and 46.4% for boys and girls, respectively. Older children (OR = 0.61; CI = 0.44-0.84; P < .01) and those with higher MC in locomotor skills (OR = 0.96; CI = 0.93-0.99; P < .01) were less likely to present WHtR ≥ 0.5. Sex and object control skills were not associated with WHtR ≥ 0.5. CONCLUSIONS: To reduce the risks of central obesity in children, health practitioners should focus on increasing competence in locomotor skills since preschool years.

Critical teaching incidents. Recollections of deaf college students.

In interviews with 56 deaf college students, we collected accounts of 839 "critical incidents" describing effective and ineffective teaching. From those incidents, 33 specific teaching characteristics were derived and were analyzed in relation to teacher, student, and course variables. Our primary goal was to identify the teaching characteristics underlying deaf students' recollections about their classroom learning experiences. The most frequently mentioned characteristics are similar to those found in studies of hearing college students, particularly within the domain of Teacher Affect. The teacher's ability to communicate clearly in sign language, however, was not only a characteristic unique to deaf college students but also the most frequently occurring characteristic of effective teaching in this study.
