Researchers in Uganda tested 362 children and teenagers with sickle cell disease (SCD) using spirometry, a simple breathing test that measures how well the lungs work. They discovered that 41.7% showed abnormal lung function patterns, yet most had no obvious symptoms.
This matters because lung damage in SCD develops silently over time. Catching it early can significantly improve your child's quality of life as they move into adulthood.
Lung problems get worse as your teen ages
The study found a striking age pattern: young children aged 8–12 had three times the risk of lung problems, while teenagers aged 13–18 had over 13 times the risk. The longer your child lives with SCD, the more likely lung damage becomes—unless preventive steps are taken.
Most children showed a "restrictive" breathing pattern (lungs can't expand fully), followed by an "obstructive" pattern (air gets trapped, similar to asthma). Some had both problems combined.
Four factors that increase risk—and what you can control
The research identified specific risk factors. While age is unavoidable, parents have direct influence over three others:
- Undernutrition: Underweight children had four times the risk of lung problems. Adequate nutrition is vital for lung health, not just growth.
- Incomplete vaccination: Missing pneumococcal vaccine doses increased risk by 3.5 times. This is preventable through your child's regular healthcare visits.
- Previous acute chest syndrome: Children who experienced this serious SCD complication showed higher lung damage risk, highlighting the importance of preventing crises.
What this means for monitoring your teen's health
This Uganda-based study reveals a universal pattern in SCD care: lung health often isn't monitored as routinely as it should be. Many families focus on managing acute pain and crises, but this research makes a clear case for preventive screening. Regular spirometry testing—not just blood tests—should be part of your child's annual SCD care plan.
The evidence here is limited to one country and one population, so discuss these findings with your child's paediatrician to understand how they apply to your family's specific situation.
- Request annual spirometry testing as part of your child's routine SCD monitoring, starting now.
- Ensure your child completes all pneumococcal vaccine doses at your scheduled appointments.
- Work with your healthcare team to maintain healthy weight through proper nutrition support.
