Asthma control in the quality of life levels of asthmatic patients' caregivers: a systematic review with meta-analysis and meta-regression.

To perform a systematic review with meta-analysis and meta-regression to correlate the total scores of asthma control with the increase in the total scores of health-related quality of life levels of parents of asthmatic children. The search was carried out in the following databases: PubMed (MEDLINE); Embase and ScienceDirect (Elsevier); SciELO and LILACs (Bireme) in June 2017. The included studies assessed asthma control through the Asthma Control Questionnaire (ACQ), Asthma Control Test (C-ACT/ACT), and Global Initiative for Asthma (GINA) questionnaires, whereas the Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ) was applied to assess the HRQoL of parents and family members. 294 articles were evaluated in the selected databases, of which (n=38) were excluded for duplicity; (n=239) after the reading of the titles and abstracts and (n=5) after reading the studies in full, totaling 12 studies eligible for the meta-analysis. Of the 12 eligible articles, 11 (92%) were published in the last five years, and evaluated children and adolescents aged 1-20 years, totaling 2804 samples. In the evaluation of the correlation between the disease control scores by ACQ and C-ACT/ACT, the results were satisfactory for both ACQ analyses [R The results show that asthma control levels can influence the total HRQoL scores of parents or relatives of children and adolescents with asthma.
