Abstract

Introduction: To examine the association between objectively measured moderate to vigorous physical activity (MVPA) and total physical activity with school absenteeism due to illness or injury among children and adolescents. Design: Cross-sectional study. Setting: National Health and Nutrition Examination Survey 2003 to 2006. Participants: A total of 1249 children (aged 6-11 years) and 1747 adolescents (aged 12-17 years). Measures: School absenteeism was categorized as no/minimal school absenteeism (0-8 missed school days in the past 12 months), moderate absenteeism (9-17 missed days), or severe absenteeism (18+ missed days). Physical activity was objectively measured via accelerometry. Analysis: Multinomial logistic regression. Results: Children in the most active quartile had 89% reduced odds of severe absenteeism relative to the least active quartile (odds ratio [OR]: 0.11; 0.95% confidence interval [CI]: 0.02-0.48); results were similar for MVPA. For adolescents, those in the most active quartile for MVPA had a 41% reduced odds of having moderate (vs no/minimal) absenteeism (OR = 0.59; 95% CI: 0.35-0.99). For children, a multiplicative interaction effect of MVPA and poverty level on severe absenteeism was observed (OR = 0.98, P = .02). Conclusion: Higher levels of physical activity were associated with lower odds of severe school absenteeism. Such an observation is important, as school absenteeism strongly contributes to academic performance. Particular attention for promoting physical activity and closely monitoring school absenteeism among youth below the poverty level may be warranted.
