Insights
Childhood pneumonia risk factors in low-income countries include unclean cooking fuel, incomplete immunization, and lack of exclusive breastfeeding. Addressing these modifiable determinants can significantly reduce pneumonia burden in young children.
Area of Science:
- Pediatric infectious diseases
- Global child health
- Environmental health
Background:
- Childhood pneumonia is a major cause of illness and death in low- and middle-income countries.
- Risk factors involve a complex mix of socioeconomic, environmental, and modifiable elements.
Purpose of the Study:
- Investigate key determinants of pneumonia in children aged 2-59 months in resource-limited settings.
- Focus on healthcare access, nutritional status, and environmental exposures.
Main Methods:
- Retrospective hospital-based case-control study.
- Utilized medical records of children aged 2-59 months.
- Extracted data on demographics, exposures, immunization, nutrition, and feeding practices.
Main Results:
- Significant risk factors identified: unclean cooking fuel, incomplete immunization, and lack of exclusive breastfeeding for 6 months.
- Maternal age ≥25 years also linked to increased risk.
- Malnutrition showed a protective effect; zinc supplementation showed a moderate effect.
Conclusions:
- Childhood pneumonia is strongly linked to modifiable factors like breastfeeding, immunization, nutrition, and household energy sources.
- Targeted interventions for these factors can substantially decrease pneumonia prevalence in resource-limited areas.
Background:
Childhood pneumonia remains a leading cause of morbidity and mortality in low- and middle-income countries, driven by a complex interplay of socioeconomic, environmental, and modifiable risk factors.
Objective:
To investigate determinants of pneumonia among children aged 2-59 months in resource-limited settings, with a focus on healthcare, nutritional, and environmental factors.
Methods:
A retrospective hospital-based case-control study was conducted using medical records of children aged 2-59 months. Cases were physician-diagnosed pneumonia based on WHO IMCI criteria, while controls were children without respiratory illness presenting for unrelated conditions. Data on demographics, household exposures, immunization, nutrition, and feeding practices were extracted using a standardized form.
Results:
Multivariable analysis identified significant risk factors: use of unclean cooking fuel (AOR = 2.01; 95% CI: 1.25-3.23), incomplete immunization (AOR = 2.78; 95% CI: 1.24-6.20), and lack of exclusive breastfeeding for 6 months (AOR = 2.10; 95% CI: 1.32-3.34). Maternal age ≥25 years was also associated with increased risk (AOR = 2.04; 95% CI: 1.26-3.31). Malnutrition showed an unexpected protective effect (AOR = 0.13; 95% CI: 0.08-0.23), while zinc supplementation showed a moderate effect (AOR = 1.63; 95% CI: 1.01-2.64). No significant associations were observed for HIV status, vitamin A supplementation, smoking exposure, child age, sex, or household crowding.
Conclusion:
Childhood pneumonia in under-five children is strongly influenced by modifiable factors, particularly breastfeeding practices, immunization coverage, nutritional status, and household energy sources. Targeted interventions addressing these determinants may substantially reduce the burden of pneumonia in resource-limited settings.
