Identification of preschool children with asthma from low-income families in Los Angeles, CA

Abstract

Few studies have addressed asthma screening in the preschool age group. Early asthma recognition and intervention in preschool children may reduce costs related to unscheduled medical care and missed school and work. To facilitate an early recognition and referral process for asthma in a preschool education program in Los Angeles, CA. We administered a 7-question survey to parents and guardians of children aged 12 months to 6 years in the prekindergarten program of a large school district in Southern California. English and Spanish survey questions addressed health care use, school absenteeism, and asthma symptoms. Postsurvey reports to parents recommended clinical evaluation of children who had probable asthma. Of the 609 surveys returned from 8 centers (> or = 80% survey return rate), 12% were positive for probable asthma and only 5.4% of these cases had been previously diagnosed. Of the 12% found to have a high probability of asthma, 3 independent factors were associated with a lower likelihood of prior asthma diagnosis: Hispanic descent; Spanish speaking; and medicine use 2 or more times per week for symptoms such as cough, chest tightness, trouble breathing, or wheezing. Symptoms at play, during the day, and at night were noted in 35% to 44% of the preschoolers. Cough was the most frequently reported symptom (71.9%, n = 424). A school-based screening process in an early education program can help identify preschool children with a high probability of asthma and offer a basis for early recognition and intervention.
