4. Discussion
The purpose of this study was to explore the level of knowledge, attitude, and practice behaviors of caregivers (i.e., parents and guardians) in the management of childhood asthma in Oyo State, Nigeria.
Most participants in the current study were mothers [n =156 (87.6%)]. This is expected since asthma is more prevalent in young children of young mothers. This study has presented data on the level of knowledge of caregivers about childhood asthma management practices in Oyo state, Nigeria highlighting the individual, behavioral, psychosocial, and environmental risk factors associated with asthma management practices. Mothers are expected to be more prevalent concerning asthma management since they are the primary caregivers of children below the age of 5 years old and mostly attend the child welfare clinic in rural Nigeria. Another local study found mothers to be the main caregivers attending the clinic with their children.5
Most of the children were boys aged ≥5 years. This finding is similar to that of a local study that found most children with asthma (60.9%) to be male within the preschool (2-5 years) and school-age (6-12 years).2 Further, the study found that the ages of asthmatic children ranged from 2 to 11 years with a mean age of 6.4 years.2 The prevalence of caregiver-reported asthma (98.3% ) in our study is comparable to that reported from other parts of Africa like Tanzania, Asia (Saudi Arabia, Pakistan, and China), and tropical countries.11,12,13,14
Study participants were interviewed during their visit to the child welfare clinic at the PHCs and pediatric department of the State Hospital where patients with unstable, difficult-to-control/severe asthma are being received; therefore, participants' level of knowledge and practice may vary for several reasons. Parents whose child has difficulty or hard-to-control asthma will more likely visit the PHCs and State hospitals, visit the doctors/nurses often, and as a result be more knowledgeable about asthma. Another reason may be that the state clinic has specialized pediatric doctors that provide specialized care and education to patients each time they visit the hospital. However, in this analysis, study participants were not subcategorized according to the healthcare settings, and hence, the caregiver’s level of knowledge and practice is not determined by the level of care received (whether caregivers attended the CWC at the PHC/ State hospital or not).
One potential factor that may explain the utilization of PHCs and the pediatric department of the State hospital may be the caregiver’s perception of disease severity and control. Besides, it is important to take into consideration the fact that the assessment of childhood asthma severity is based mainly on personal caregiver’s reports and not necessarily a medically diagnosed report. Asthma severity levels in children may be affected by caregivers’ poor perception of asthma symptoms in their children and difficulties in caregivers’ recognition of signs and symptoms of the disease in their children. While the caregiver’s perception of the disease has been linked to poor asthma management, in this study, there were other factors such as the degree of a child’s exposure to pollutants and level of asthma severity that contributed to the caregiver’s asthma care-seeking behavior and treatment for their children.
Family history of asthma was obtained, and the findings differ from prior studies that reported positive asthma history among most of their respondents.2, 11 Most of the respondents [n=106 (59.6%)] in this study reported no family history of asthma, and 72 respondents (40.4%) reported a history of asthma in the parents or close relatives. It is, however, low compared to the history of asthma 56 (52.8%) among children that attended the pediatric chest clinic of the Wesley Guild Hospital (WGH), Ilesha, Nigeria reported by Kuti et al., 2017. This finding correlates with the study on parents and guardians of children with asthma that attended the general pediatric and pediatric pulmonology outpatient clinics at King Abdullah Specialist Children’s Hospital, King Abdulaziz Medical City for National Guard, Riyadh, Saudi Arabia (during the period from August 2016 to March 2017).11 The relatively low response of family history reported in this study may be because family history is often overlooked as an important risk factor and caregivers may not consider family history as an indicator of risk for childhood asthma due to poor knowledge, myths, misconception, or cultural factors.
Further, since the source of asthma information is known to have an impact on knowledge and asthma management practices, it may be worthwhile to discuss caregivers’ sources of health information. The Internet is a growing source of health information in developing countries such as Nigeria, but in this study, 68% of participants reported primary care providers such as doctors and community health nurses as their source of information about asthma. Considering the poor standard of asthma care and the lack of asthma educators in many health facilities in Nigeria, the role of the radio, TV, and Internet as alternative sources of asthma education need to be enhanced. Professional and certified health education communication channels on asthma guidelines-based care and asthma self-management education need to be available for patients and their families.
Most of the participants in this study had a moderate knowledge score in the total knowledge and all knowledge subcategories (myths and beliefs, general knowledge, and knowledge of associated aspects) using the validated AKQ. A local study investigating a similar topic reported that the level of knowledge about childhood asthma was significantly poor among caregivers (38.5%) in the pediatric chest clinic of the Wesley Guild Hospital (WGH), Ilesha, Nigeria using a different AKQ with a mean knowledge score of 11.2 (SD =3.7) which ranged from1 to 18.5 The difference in their finding and this study may be related to the lower educational qualifications of caregivers in Ilesha (a smaller city) compared to Ibadan (a metropolitan city).
In the current study, participants were most knowledgeable about asthma pathophysiology (such as the role of airway inflammation), triggers of asthma exacerbation in their children, and questions related to diagnosis and treatment. The findings agree with the reports from Rastogi et al., 2013 and AlOtaibi, & AlAteeq, 2018. These studies found better knowledge among caregivers in questions related to symptoms of asthma, asthma triggers in their children, diagnosis and treatment, pathogenesis, and nature of the disease. The findings of this study agree with Rastogi et al., 2013 who found that caregivers had better knowledge of asthma triggers and were aware of the importance of using controller medications. The result of the current study also showed that caregivers were knowledgeable about the associated aspects of asthma, with 94.9% having a moderate level of knowledge. However, a severe deficit of knowledge was observed particularly in questions related to the myths and beliefs about asthma; where 31.5% of participants had fair knowledge and 1.7% had poor knowledge. In this subcategory of knowledge (myths and beliefs regarding asthma), caregivers were presented with statements such as “asthma is a curse from the gods,” “childhood asthma can be cured by homemade or herbal remedies,” and “pray before going to the clinic when your child has an asthma attack.” Caregivers’ misconceptions about asthma medication are reflected in their actual practice in managing asthma in their children, as almost half of the respondents in this study reported providing alternative therapy for asthma such as massage, homemade, and herbal remedies. Such therapies were more widely used by caregivers whose knowledge score was relatively low. This is consistent with the findings from international studies.2,15,17.
One potential factor that may explain the caregivers’ perceived susceptibility to risk and severity of asthma may be the underlying knowledge of asthma triggers. Factors associated with the asthma perception level among caregivers were family history of asthma; indoor environmental allergens e.g., house dust, cooking fuel, pets, mold, and other environmental pollutants such as tobacco smoke. Exposure to allergens may likely have contributed to asthma severity as reported by caregivers of children with asthma. The outcome of this study showed that caregiver’s knowledge of allergens and generated smoke was significantly associated with perceived susceptibility to an asthma attack, which was similarly reported by Rastogi et al.,2013, who found that knowledge of perceived triggers (e.g., infection, type of food consumed, and exercise) influenced caregiver’s perception of an asthma attack. Given the level of awareness about common triggers of asthma exacerbation, caregivers’ perception of risk can be low in terms of the frequency of symptoms and decreased risk of severe asthma attacks. Avoidance of exposure to dust and cleaning supplies in children with asthma will go a long way in ensuring good asthma control and ultimately improve their quality of life.
The current study showed that the severity of asthma was also associated with caregivers’ knowledge of early asthma symptoms. caregivers with knowledge of early asthma symptoms (i.e., recurrent wheezing and dry cough at night) reported high usage of quick-relief medicine for their children during asthma exacerbations. Similarly, the frequency of asthma attacks was found to be significantly related to the pre-identification of wheezing and dry cough at night as early symptoms of childhood asthma. In this study, caregivers with knowledge of early wheezing episodes (especially during or after exercise) were less likely to visit the clinic but more likely to visit the clinic with recurring dry cough episodes. The results suggest that caregivers would prefer to use cough medicines purchased from the patent and proprietary medicine vendors (PPMVs) in their community or use home remedies to help relieve cough symptoms in their children. These findings were similar to those reported by Rastogi et al. (2013) and Soo & Tan (2014). Despite the relatively good knowledge of asthma in this study, caregivers did not visit the primary health care center for asthma exacerbations like wheezing but went to emergency visits for night-dry cough, which led to hospital admissions. This also implies that caregivers are unable to translate their knowledge and awareness into action in situations of asthma exacerbations. Poor knowledge of early asthma symptoms may be associated with either frequent hospital admission or low clinic visits (i.e., frequency of healthcare-seeking behavior).
Socio-demographic class is an important predictor of asthma control in this study, which has also been reported in other studies.2,13,16 In these studies, the authors found that caregivers’ low income and unemployment status were significant predictors of poor asthma control in Pakistan, Nigeria, and the USA. In this current study, the result showed that the level of asthma control was not significantly related to caregivers' education, though more proportions of caregivers with children having well-controlled asthma had at least a secondary level education of education. This observation may be related to the fact that highly educated caregivers may have inadequate knowledge, incorrect caregiver-reported diagnosis, and wrong perception of asthma management practices.2 On the other hand, income level was significantly associated with asthma control in this study. Caregivers in the low-income category are at risk of the financial burden that makes them unable to afford the cost of proper asthma care for their children; hence, predisposes them to poor management of childhood asthma. This also implies that if asthma treatment services are easily accessible and affordable to all socio-economic classes in the community, asthma exacerbations will reduce leading to better asthma practices and improved quality of life for both the caregivers and their children.
In summary, our result suggests that caregivers of asthmatic children have moderate knowledge of the common asthma symptoms and aggravating factors but poor knowledge regarding fundamental asthma treatment and management. The challenge for future health promotion and public health lies in the careful identification of caregivers’ experiences, their needs in managing the care of their asthmatic child, and factors that facilitate or hinder the performance of appropriate asthma management practice behaviors. This study revealed that caregivers, particularly parents, play an important role in shaping healthcare behavior in their children. For better asthma management and control, an optimal public health approach is needed to identify and target underserved communities that suffer poorer asthma outcomes and improve caregivers’ knowledge and skills in asthma management practices. To holistically improve child asthma care and outcomes, asthma education campaigns, including community-targeted initiatives to engage caregivers, healthcare professionals, and the community at large are recommended. This study, however, contributes new findings to the existing literature done locally about childhood asthma management practices in Nigeria; and how social and environmental factors influence proper asthma management practice behaviors of caregivers.
Regarding the limitations of this work, this study was carried out in primary health care centers and state pediatric outpatient clinics with the selection of participants through a convenience sampling method. Although data saturation was achieved in the analysis, there is a possibility that other important aspects of the caregiver’s experience of asthma management were not captured. In addition, we used an interviewer-administered questionnaire in this research, interviewer bias recall bias cannot be excluded. Information on the frequency and severity of asthma symptoms reported by caregivers may not be accurate. Study participants may erroneously provide inaccurate or false reports depending on their ability to recall past asthma episodes, hence a recall bias. Despite these limitations, this study has contributed to the inadequate data on childhood asthma and factors associated with proper asthma management in a developing country. This study has also revealed insights into the level of knowledge, attitude, and practice behaviors of caregivers in the management of asthma in their children in developing countries like Nigeria, and examined factors associated with the barriers and benefits of proper asthma management practices.
