“…Asthma severity, particularly nighttime awakenings, is also associated with parent absenteeism from work (Diette et al, 2000). Recent prevalence studies among 7- to 18-year-olds have found that 28% to 50% of those who report asthma-like symptoms have never been diagnosed with asthma (Carter, Debley, & Redding, 2005; Clark et al, 2002; Hetlevik, Ploen, Nystad, & Magnus, 2000; Lewis et al, 2004; Lowe & Burr, 2001; Siersted, Boldsen, Hansen, Mostgaard, & Hyldebrandt, 1998; Yeatts, Shy, Sotir, Music, & Herget, 2003). The rates of undiagnosed asthma are concerning because untreated asthma is associated with significant activity limitation (Carter et al, 2005; Joseph et al, 2005; Lewis et al, 2004; Yeatts, Davis, Sotir, Herget, & Shy, 2003; Yeatts, Shy et al, 2003).…”
