Gender influences on the health of adolescents with sickle cell disease

The current study examines gender effects on disease knowledge and quality of life in adolescents with sickle cell disease (SCD) in Jamaica. We report the baseline results on 76 girls and 74 boys with mean age (16.9 ± 1.8 vs. 16.2 ±2.0 years), recruited in a larger intervention study. Girls had higher knowledge scores (15.3 ± 4.2 vs. 13.3 ± 4.2 p=.004), poorer overall QOL scores (70.1 ± 19.6 vs. 77.2 ± 17.8 p=0.02) but similar severity scores to boys. Girls also had significantly lower scores on many QOL domain scores: Pain occurrences over the course the past month (Pain and Hurt:77.49 ± 23.3 vs. 85.37 ± 17.13); concerns about seeking health services for pain (Worry1:63.73 ± 26.21 vs. 75.33 ± 24.62); confidence in self-management & treatment effects (Treatment: 72.25 ± 23.6 vs. 80.73 ± 18.90) and SCD disclosure & empathy from others (Communication II: 47.44 ± 1.02 vs. 61.71 ± 29.41). Knowledge was positively predicted by age, higher education, greater household possessions and was higher in girls; whereas QOL was lower in girls and those with greater disease severity and higher with higher education. In conclusion, there is a significant gender differential in disease knowledge and QOL among adolescents with SCD. Interventions will need to address the lower QOL in girls and lower disease knowledge among boys.
