Background: Pediatric Asthma Quality of Life Questionnaire (PAQLQ) provides detailed information on QoL in asthmatic children, whereas Childhood Asthma Control Test (C-ACT) Questionnaire is the most validated instrument for asthma control. No study assessed the relationship between C-ACT and QoL in children by means of those instruments. The aim of this study was to determine whether a QoL estimation is possible using the C-ACT questionnaire in asthmatic children. Methods: Medical history, spirometry, C-ACT, and PAQLQ were assessed in 144 (60% male) outpatient asthmatic children from September 2011 to November 2014. A generalized linear model (GLM) for the prediction of PAQLQ was obtained through a stepwise procedure starting from a full model with all C-ACT items, and predictive nomograms were created. Results: Fifty-five (38%) well-controlled (WC) asthma, 37 (26%) partially controlled (PC) asthma, and 52 (36%) uncontrolled asthma (UA) patients were enrolled. Persistent asthmatics (PA) were significantly more uncontrolled (p < 0.0001). A significant reduction in FEV 1, FEV 1/FVC, and FEF 25–75 (p = 0.005, p < 0.0001, and p < 0.001, respectively) was found in WC vs. UA. Through a stepwise process, a reduced model showed a positive relationship between the PAQLQ and the four items of C-ACT. The regression equations for predicted PAQLQ were ln(PAQLQ) = 1.17 + 0.05*C-ACT2 + 0.03*C-ACT3 + 0.04*C-ACT6 + 0.03*C-ACT7. Thus, a nomogram was constructed. Conclusion: The designed nomogram provides a highly predictive assessment of QoL in individual patients, facilitating a more comprehensive assessment of asthmatic children in usual clinical care.
