Few studies have examined the impact of physical activity (PA) programs during the preschool day, with only two rooted in an academic curriculum. PA has been shown to improve components of classroom behavior in preschoolers. Poor classroom behavior can be indicative of early attention-deficit/hyperactivity disorder (ADHD) symptomology, which is seen in children as young as three years old. However, no studies have examined curriculum-based PA to improve classroom behavior. PURPOSE: To examine the impact of a curriculum-based PA intervention on classroom behavior variables in preschoolers. METHODS: Children (n=52, mean±sd: age=3.6±0.8 years, BMI percentile=50.1±27.1) attending two preschools were randomized to the Preschool Activity, Diet, and Sleep (PADS) intervention or the health tracking (CON) group. PADS consisted of integrating PA lessons into Massachusetts Early Learning Standards. The Strengths and Difficulties Questionnaire (SDQ) behavioral screening tool was used to assess classroom behavior which includes a total difficulties score and subscales encompassing hyperactivity/inattention, emotional problems, conduct problems, peer problems, and prosocial behavior. The SDQ was completed by classroom teachers for each child at baseline, 6 weeks, and 12 weeks. A repeated measures ANOVA was utilized to examine intervention effects on children’s classroom behavior variables. RESULTS: Children at the CON school exhibited greater hyperactivity/inattention (PADS=2.3±2.5, CON=4.1±3.5), emotional problems (PADS=0.3±0.6, CON=2.6±2.4), conduct problems (PADS=0.8±1.3, CON=2.9±3.2), peer problems (PADS=0.3±1.0, CON=1.2±1.4), and total difficulties (PADS=4.0±3.8, CON=10.9±8.0) at baseline compared to the PADS school. There were no statistically significant effects of time or intervention by time for classroom behavior variables. CONCLUSION: These data suggest a curriculum-based PA intervention did not lead to change in teacher-reported classroom behavior variables. Lack of intervention effect in this population could be due to lack of specificity of intervention components targeting classroom behavior. Future studies should incorporate cognitive skills linked to early ADHD symptomology in PA lessons, include objective behavior measures, and utilize a larger sample size.
