Knowledge and perceptions on childhood asthma among care-takers of children with asthma at a National Referral Hospital in Western Kenya: a descriptive study

Parental knowledge and attitudes toward asthma in Jordanian children with asthma, a multi-center cross-sectional study

OBJECTIVE

We explored Jordanian caregivers' knowledge, attitudes, and practices (KAP) toward asthma in their children.

METHODS

This cross-sectional investigation was conducted on caregivers visiting the pediatrics clinic at the Jordan University Hospital and King Abdullah University Hospital between December 2021 and January 2023. KAP were measured using a literature-validated questionnaire. Differences in KAP scores across participants' characteristics were examined using the student-t test and ANOVA.

RESULTS

A total of 108 caregivers were included in the final analysis. Caregivers were aged 30 to 40 years (54.6%) and had at least secondary education (90.7%). The majority of participants displayed appropriate knowledge with respect to asthma's clinical course. Furthermore, the greater portion of caregivers were knowledgeable about preventing asthma attacks and treating their children during said attacks. Factors affecting knowledge of asthma included age of mothers (p < .05). On the other hand, attitude scores were affected by occupation, type of medication, and family history of asthma (all p < .05). Moreover, employee mothers, children well controlled on both Asthma Control Test and Global Initiative for Asthma scores, and having no pediatric intensive care unit admissions were associated with higher practice treatment scores (all p < .05). Overall practice score was weakly, yet positively correlated with knowledge scores (r = 0.195, p = .043). Similarly, negative attitudes were weakly correlated with higher knowledge scores (r = 0.199, p = .039).

CONCLUSION

While the knowledge and practice scores were satisfactory, the clinical status of children with asthma was unsatisfactory. Future studies should examine factors associated with caregiver insecurity and measure their extent of applying asthma prevention guidelines.

Asthma symptoms, spirometry and air pollution exposure in schoolchildren in an informal settlement and an affluent area of Nairobi, Kenya

BACKGROUND

Although 1 billion people live in informal (slum) settlements, the consequences for respiratory health of living in these settlements remain largely unknown. This study investigated whether children living in an informal settlement in Nairobi, Kenya are at increased risk of asthma symptoms.

METHODS

Children attending schools in Mukuru (an informal settlement in Nairobi) and a more affluent area (Buruburu) were compared. Questionnaires quantified respiratory symptoms and environmental exposures; spirometry was performed; personal exposure to particulate matter (PM2.5) was estimated.

RESULTS

2373 children participated, 1277 in Mukuru (median age, IQR 11, 9-13 years, 53% girls), and 1096 in Buruburu (10, 8-12 years, 52% girls). Mukuru schoolchildren were from less affluent homes, had greater exposure to pollution sources and PM2.5. When compared with Buruburu schoolchildren, Mukuru schoolchildren had a greater prevalence of symptoms, 'current wheeze' (9.5% vs 6.4%, p=0.007) and 'trouble breathing' (16.3% vs 12.6%, p=0.01), and these symptoms were more severe and problematic. Diagnosed asthma was more common in Buruburu (2.8% vs 1.2%, p=0.004). Spirometry did not differ between Mukuru and Buruburu. Regardless of community, significant adverse associations were observed with self-reported exposure to 'vapours, dusts, gases, fumes', mosquito coil burning, adult smoker(s) in the home, refuse burning near homes and residential proximity to roads.

CONCLUSION

Children living in informal settlements are more likely to develop wheezing symptoms consistent with asthma that are more severe but less likely to be diagnosed as asthma. Self-reported but not objectively measured air pollution exposure was associated with increased risk of asthma symptoms.

Preterm birth, birth weight, infant weight gain and their associations with childhood asthma and spirometry: a cross-sectional observational study in Nairobi, Kenya

BACKGROUND

In sub-Saharan Africa, the origins of asthma and high prevalence of abnormal lung function remain unclear. In high-income countries (HICs), associations between birth measurements and childhood asthma and lung function highlight the importance of antenatal and early life factors in the aetiology of asthma and abnormal lung function in children. We present here the first study in sub-Saharan Africa to relate birth characteristics to both childhood respiratory symptoms and lung function.

METHODS

Children attending schools in two socioeconomically contrasting but geographically close areas of Nairobi, Kenya, were recruited to a cross-sectional study of childhood asthma and lung function. Questionnaires quantified respiratory symptoms and preterm birth; lung function was measured by spirometry; and parents were invited to bring the child's immunisation booklet containing records of birth weight and serial weights in the first year.

RESULTS

2373 children participated, 52% girls, median age (IQR), 10 years (8-13). Spirometry data were available for 1622. Child immunisation booklets were available for 500 and birth weight and infant weight gain data were available for 323 and 494 children, respectively. In multivariable analyses, preterm birth was associated with the childhood symptoms 'wheeze in the last 12 months'; OR 1.64, (95% CI 1.03 to 2.62), p=0.038; and 'trouble breathing' 3.18 (95% CI 2.27 to 4.45), p<0.001. Birth weight (kg) was associated with forced expiratory volume in 1 s z-score, regression coefficient (β) 0.30 (0.08, 0.52), p=0.008, FVC z-score 0.29 (95% CI 0.08 to 0.51); p=0.008 and restricted spirometry, OR 0.11 (95% CI 0.02 to 0.78), p=0.027.

CONCLUSION

These associations are in keeping with those in HICs and highlight antenatal factors in the aetiology of asthma and lung function abnormalities in sub-Saharan Africa.

Childhood Asthma-Management Practices in Rural Nigeria: Exploring the Knowledge, Attitude, and Practice of Caregivers in Oyo State

Background: Caregivers of asthmatic children have a poor knowledge of proper asthma-management practices in Nigeria. This study examined the knowledge, attitudes, and practice behaviors of caregivers in the management of asthma in children under 5 years of age in Oyo State, Nigeria. Methods: While a mixed method was used in the original research, this brief describes the quantitative method used in this study to evaluate caregivers' asthma-management practices. A 55-item questionnaire on childhood asthma knowledge, attitude, and practice was administered during child welfare-clinic visits to 118 caregivers. Data were analyzed using the IBM SPSS Version 25.0. Statistical significance was set at p < 0.05 and 95% CI. Result: More than 70% of caregivers knew that asthma is associated with airway inflammation and about 90% knew that flu infections triggered asthma attacks in their children. Caregivers with a higher income (OR = 3.0; 95% CI = 1.558-5.778; p = 0.001) were 3.0 times more likely to practice proper asthma-care behavior than those with a lesser income. Conclusions: Childhood asthma remains underdiagnosed and undertreated in Nigeria. An optimal public health approach is needed to identify and target underserved communities that suffer poorer asthma outcomes and to improve caregivers' knowledge and practices of asthma management.

Knowledge, Attitudes, and Practices of Influenza Vaccination among Parents of Children with Asthma: A Cross-Sectional Study

Asthma is the most common chronic disease in childhood. Exacerbation is a significant problem for asthmatic patients, and viral infections remain the most frequent triggers of asthma exacerbations. This study explored knowledge, attitudes, and practices (KAP) of parents of asthmatic children towards providing influenza vaccine to their children. This cross-sectional study enrolled parents of asthmatic children who visited the outpatient respiratory clinics of two Jordanian hospitals. The present study enrolled 667 parents of asthmatic children (62.8% female). The median age of the participants' children was 7 years. The results showed that 60.4% of the children with asthma never received a flu vaccine. Most of those who had received the flu vaccine reported that the side effects were mild (62.7%). Asthma duration was positively and significantly associated with increased vaccine hesitancy/rejection (OR = 1.093, 95% CI = (1.004-1.190), p = 0.04; and OR = 1.092, 95% CI = (1.002-1.189), p = 0.044, respectively). As the attitude towards flu vaccine score increases, odds of vaccination hesitancy/rejection decreased (OR = 0.735, 95% CI = (0.676-0.800), p < 0.001; and OR = 0.571, 95% CI = (0.514-0.634), p < 0.001, respectively). The main reasons for vaccination hesitancy/refusal included "I don't think my child needs it" (22.3%) followed by "I forget it" (19.5%). The rate of vaccination among children was low and emphasized the necessity of encouraging parents with asthmatic children to vaccinate their children by conducting health awareness campaigns and also emphasized the role of doctors and other healthcare professionals.

Prevalence, severity and risk factors for asthma in school-going adolescents in KwaZulu Natal, South Africa

BACKGROUND

Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and risk factors for asthma in adolescents in an LMIC.

METHODS

A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.

RESULTS

A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.

CONCLUSION

Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Asthma-Related Knowledge and Practices among Mothers of Asthmatic Children: A Latent Class Analysis

Mothers’ knowledge about childhood asthma influences management practices and disease control, but validating knowledge/practice questionnaires is difficult due to the lack of a gold standard. We hypothesized that Latent Class Analysis (LCA) could help identify underlying mother profiles with similar knowledge/practices. A total of 438 mothers of asthmatic children answered a knowledge/practice questionnaire. Using answers to the knowledge/practice questionnaire as manifest variables, LCA identified two classes: Class 1, “poor knowledge” (33%); Class 2, “good knowledge” (67%). Classification accuracy was 0.96. Mothers in Class 2 were more likely to be aware of asthma-worsening factors and indicators of attacks. Mothers in Class 1 were more likely to prevent exposure to tobacco smoke (91.1% vs. 78.8%, p = 0.005). For attacks, mothers in Class 2 were more likely to go to the emergency department and follow the asthma action plan. Mothers in Class 2 more frequently had a high education level (79.5% vs. 65.2%, p = 0.004). Children in Class 2 more frequently had fully controlled asthma (36.7% vs. 25.9%, p = 0.015) and hospitalizations for attacks in the previous 12 months (24.2% vs. 10.7%, p = 0.003). LCA can help discover underlying mother profiles and plan targeted educational interventions.

Systematic review on epidemiology, interventions and management of noncommunicable diseases in acute and emergency care settings in Kenya

Introduction

Mortality and morbidity from Non-Communicable Diseases (NCDs) in Africa are expected to worsen if the status quo is maintained. Emergency care settings act as a primary point of entry into the health system for a spectrum of NCD-related illnesses, however, there is a dearth of literature on this population. We conducted a systematic review assessing available evidence on epidemiology, interventions and management of NCDs in acute and emergency care settings in Kenya, the largest economy in East Africa and a medical hub for the continent.

Methods

All searches were run on July 15, 2015 and updated on December 11, 2020, capturing concepts of NCDs, and acute and emergency care. The study is registered at PROSPERO (CRD42018088621).

Results

We retrieved a total of 461 references, and an additional 23 articles in grey literature. 391 studies were excluded by title or abstract, and 93 articles read in full. We included 10 articles in final thematic analysis. The majority of studies were conducted in tertiary referral or private/mission hospitals. Cancer, diabetes, cardiovascular disease and renal disease were addressed. Majority of the studies were retrospective, cross-sectional in design; no interventions or clinical trials were identified. There was a lack of access to basic diagnostic tools, and management of NCDs and their complications was limited.

Conclusion

There is a paucity of literature on NCDs in Kenyan emergency care settings, with particular gaps on interventions and management. Opportunities include nationally representative, longitudinal research such as surveillance and registries, as well as clinical trials and implementation science to advance evidence-based, context-specific care.

Empowering children and young people who have asthma

Asthma is the most common chronic condition of childhood. In this review, we discuss an overview of strategies to empower children and young people with asthma. The key aspects of empowerment are to enable shared decision making and self-management, and help children minimise the impact of asthma on their life. The evidence behind these strategies is either sparse or heterogenous, and it is difficult to identify which interventions are most likely to improve clinical outcomes. Wider determinants of health, in high-resource and low-resource settings, can be disempowering for children with asthma. New approaches to technology could help empower young people with asthma and other chronic health conditions.

Asthma management and control in Nigeria: the asthma insight and reality Nigeria (AIRNIG) study

Background: The state of asthma management and asthma control at the population level in Nigeria is unknown. We aimed to determine the level of asthma control and asthma management practices in Nigeria. Methods: A cross-sectional population-based study of 405 participants with current asthma (physician-diagnosed with use of asthma medication or asthma symptoms in the preceding 12 months). We determined the level of asthma control, self-perception of asthma control, health-care use, missed work/school, and medication use. Results: Asthma was controlled in 6.2% of the participants. Night-time awakening and limitation in activity in the preceding 4 weeks were reported by 77.5% and 78.3%, respectively, 56.3% and 14.1% missed work/school and had emergency room visits, respectively, and 11.6% and 38.8% used inhaled corticosteroid and short-acting beta-2 agonist, respectively, in the preceding year. About a third (34.3%) had spirometry ever performed and 46.7% had training on inhaler technique. Nearly 90% with uncontrolled asthma had self-perception of asthma control between somewhat and completely controlled. Conclusion: The level of asthma control in Nigeria is poor with a high burden of asthma symptoms and limitation in activities. This calls for a broad-based approach for the improvement in asthma care that encompasses education and access to medications.
