Insights
Childhood asthma in Maputo is linked to family history of asthma and allergies, urban living, parental smoking, and early weaning. These factors are crucial for managing pediatric asthma effectively.
Area of Science:
- Pediatric Pulmonology
- Epidemiology
- Environmental Health
Background:
- Limited research exists on childhood asthma risk factors in African populations.
- This study investigated key risk factors for pediatric asthma in Maputo, Mozambique.
Purpose of the Study:
- To identify and analyze risk factors associated with childhood asthma in Maputo.
- To provide data for improved asthma management strategies in the region.
Main Methods:
- A case-control study involving 199 children (100 asthmatic, 99 non-asthmatic) aged 18 months to 8 years.
- Data collected included family history of atopy, birth weight, environment, breastfeeding practices, and parental smoking.
- Statistical analysis using odds ratios (OR) and confidence intervals (CI) to determine risk factor significance.
Main Results:
- Asthmatic children were hospitalized more frequently (P < 0.0001).
- Significant risk factors included urban residence (OR = 6.73), parental history of asthma (OR = 26.8) or rhinitis (OR = 4), parental smoking, and early weaning (OR = 2.4).
Conclusions:
- Childhood asthma in Maputo is strongly associated with genetic predisposition (family history of asthma/rhinitis) and environmental factors.
- Urban living, parental smoking, and early cessation of breastfeeding are significant contributors to pediatric asthma development.
- Findings underscore the necessity of re-evaluating current management approaches for childhood asthma in Maputo.
Background:
Few studies have looked at risk factors for asthma in African children. We aimed to identify the risk factors associated with childhood asthma in Maputo (Mozambique).
Methods:
This case-control study included 199 age-matched children (100 asthmatic and 99 nonasthmatic) who attended Maputo Central Hospital between January 1999 and July 2000. We collected information concerning their familial history of atopy, birth weight, environment and breast-feeding. Detailed information about morbidity and treatment was obtained for each asthmatic child.
Results:
The children were aged between 18 months and 8 years; 60% were male. The asthmatic children were hospitalized more frequently than the nonasthmatic children (P < 0.0001). Most of the asthmatic children lived in the urban area of Maputo [odd ratio (OR) = 6.73, CI = 3.1-14.0, P < 0.0001], had a parental history of asthma (OR = 26.8, CI = 10.8-68.2, P < 0.0001) or rhinitis (OR = 4, CI = 1.2-13.3, P = 0.005), had at least parent who smoked and were weaned earlier than the nonasthmatic children (OR = 2.4, CI = 1.3-4.4, P < 0.001).
Conclusion:
Childhood asthma was strongly associated with a family history of asthma and rhinitis, the place of residence, having smokers as parents and early weaning from maternal breast milk. These results highlight the need to reassess the management of asthmatic children in Maputo.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
