Sickle cell disease (SCD) significantly affects physical functioning. We examined physical activity (PA) patterns in children with SCD versus a national sample and factors associated with PA and participation in physical education and organized sports.


One hundred children with SCD completed a 58-item survey with questions from the 2009–2010 National Health and Nutrition Examination Survey (NHANES) Physical Activity Questionnaire and others on physical education and sports, disease impact, and physical functioning.


Compared with NHANES participants, more children with SCD (67 vs 42%, p < .01) reported doing at least 10 min of moderate-to-vigorous intensity PA (MVPA)/week. Children with SCD also reported spending more days in MVPA (2.3 vs. 1.4 days/week, p < .01). However, fewer reported spending ³ 60 min/day in either vigorous PA (VPA) (24 vs. 43%, p = .01) or MVPA (17 vs 23%, p < .01). In addition, 90% and 48% of children with SCD participated in physical education and sports, respectively. Greater disease impact on PA and physical functioning were associated with lower participation.


Children with SCD are active at moderate to vigorous intensity for shorter durations. Negative personal beliefs about disease impact and poor physical functioning represent barriers to PA in SCD.

Sickle cell trait can pose a grave risk for some athletes. In the past few years, exertional sickling has killed nine athletes, including five college football players in training. Exercise-physiology research shows how and why sickle red cells can accumulate in the bloodstream during intense exercise bouts. Sickle cells can “logjam” blood vessels and lead to collapse from ischemic rhabdomyolysis. Diverse clinical and metabolic problems from explosive rhabdomyolysis can threaten life. Sickling can begin in 2-3 minutes of any all-out exertion, or during sustained intense exertion – and can reach grave levels very soon thereafter if the athlete struggles on or is urged on by coaches despite warning signs. Heat, dehydration, altitude, and asthma can increase the risk for and worsen sickling. This exertional sickling syndrome, however, is unique and in the field can be distinguished from heat illnesses. Sickling collapse is a medical emergency. Fortunately, screening and precautions can prevent sickling collapse and enable sickle-trait athletes to thrive in their sports.
