Asthma-Related School Absenteeism and School Concentration of Low-Income Students in California

Abstract

IntroductionAsthma is one of the leading causes of school absenteeism. Previous studies have shown that school absenteeism is related to family income of individual students. However, there is little research examining whether school absenteeism is related to school-level concentration of low-income students, independent of family income. The objective of this study was to examine whether the proportion of low-income students at a school was related to school absenteeism due to asthma.MethodsUsing data from the 2007 California Health Interview Survey, a population-based survey of California households, we examined the association between attending schools with high concentrations of low-income students and missing school because of asthma, adjusting for demographic characteristics, asthma severity, and health insurance status. Schools with high concentrations of low-income students were identified on the basis of the percentage of students participating in the free and reduced-price meal program, data publicly available from the California Department of Education.ResultsStudents attending schools with the highest concentrations of low-income students were more likely to miss school because of asthma. Students from low-income families, younger students, those with more frequent asthma symptoms, or those taking prescription asthma medications also were more likely to miss school because of asthma.ConclusionThe use of school-level interventions to decrease school absenteeism due to asthma should be explored, especially in schools with high concentrations of low-income students. Potential interventions could include school-based asthma education and disease management or indoor and outdoor air pollution control.

Structure-Function Analysis of CCL28 in the Development of Post-viral Asthma

“…It is a complex disease characterized by airway hyper-responsiveness, inflammation, and tissue remodeling resulting in episodic airflow obstruction and clinical symptoms of wheezing, coughing, and shortness of breath (2). Asthma is a major public health issue in the United States as it is the number one illness leading to school absences in children (3), and in 2010 alone asthma accounted for 3404 deaths and 1.8 million emergency department visits (4). Currently, there is no cure for asthma.…”

School–Supervised Use of a Once-Daily Inhaled Corticosteroid Regimen: A Cluster Randomized Trial

“…37 Risk factors for absenteeism include poor health, obesity, poorly controlled asthma, low household income, and attending schools where many students are NSLP eligible. 38,39 Our null finding should be viewed cautiously in light of the robust literature on school-based asthma programs in general and supervised therapy in particular. 40 By minimizing the research team's involvement with program implementation, we likely identified several areas critical to bridging the gap between efficacy and effectiveness.…”

Analyzing Who, When, and Where: Data for Better Targeting of Resources for School‐Based Asthma Interventions

“…This is an increase from the previous academic year of 2330 out of 6253 asthmatic students not under treatment. A study in California supports the idea of school‐level interventions to decrease school absenteeism due to asthma attacks …”
