**1. Introduction**

Asthma is a serious childhood issue that still imposes an enormous burden on children, their families, and health care systems [1]. Currently, 339 million people worldwide suffer from asthma, and approximately 14% of children are affected [2]. In 2019, asthma caused 2.29% of total disability adjusted life years and 3.76% of years lived with disability in children with asthma aged 5–14 years worldwide [3]. Besides, pediatric asthma affects the parents through the loss of productivity at the workplace and family disruption [1, 4].

The Global Atlas of Asthma stated that asthma is one of the main causes of hospitalization in children [5]. Additionally, a recent study noted that children and adolescents with asthma had a higher number of outpatient and emergency department (ED) visits in comparison with non-asthmatic children [6]. The lack of asthma control can place severe limits on the daily life of children and is sometimes fatal. Treatment and effective management of asthma can save lives [7]. Patient education and self-management plans have been convincingly shown to reduce exacerbations requiring hospitalization [5]. Besides, a growing emphasis has been on involving families in health care and assessing their needs. Family education consists of the active involvement of the child and his or her parent in the process of chronic disease management and treatment [8, 9].

A recent systematic review examined the effectiveness of school- and communitybased nurse-led educational interventions on asthma management for school-age children and their parents [10]. This literature review included eight studies published from 2014 to 2016, which is a limited sample. It reported that schooland community-based interventions led by nurses improved knowledge and skills related to asthma self-management in school-age children with asthma and their parents. Furthermore, Walter and colleagues systematically reviewed the effect of school-based family asthma education programs on QOL and asthma exacerbations in children with asthma aged 5–18 years. This review reported a limited number of randomized control trials (n = 6) published from 2004 to 2010. It revealed that school-based family asthma educational programs for children and their caregivers can have a positive effect on QOL and asthma management of children with asthma [11].

Numerous studies assessed the impact of family education on asthma major outcomes. The findings of these interventions were controversial. This study aimed to report results from recent studies on the effectiveness of family education on clinical outcomes in children with asthma.
