Prediction of Functional Academic Outcomes by Fine Motor Skills in Individuals With Sickle Cell Disease.

Individuals with sickle cell disease (SCD) are at heightened risk of poor neurocognitive and academic outcomes. The relationship between fine motor skills and academic outcomes is not well understood. To compare the fine motor skills of individuals with SCD with normative expectations, test whether demographic and medical factors are associated with fine motor performance, and determine the impact of fine motor performance on academic performance. Cross-sectional. St. Jude Children's Research Hospital. Individuals with SCD (N = 376; ages 8-24 yr). Fine motor outcomes included visual-motor integration, manual dexterity, and graphomotor speed. Academic outcomes included math fluency and word reading. Demographic and medical variables were obtained via medical records and interviews. Compared with normative expectations, the performance of individuals with SCD on all fine motor measures was lower than expected. Male sex, lower socioeconomic status, and lower oxygen saturation was associated with slower graphomotor speed. Lower socioeconomic status and older age were associated with lower visual-motor integration scores. Performance on all fine motor measures was positively associated with math fluency and word reading. Individuals with SCD exhibited poorer than expected fine motor skills across multiple motor domains, and these deficits were associated with poorer academic outcomes. Early referral to intervention services for fine motor skills may facilitate improved academic outcomes for individuals with SCD. Plain-Language Summary: This study had three objectives: (1) Compare the fine motor skills of people with sickle cell disease (SCD) with normative expectations, (2) test whether demographic and medical factors are associated with fine motor performance, and (3) determine the impact of fine motor performance on academic performance. We found that SCD is a risk factor for lower than expected fine motor performance across multiple fine motor domains and that these deficits also affect functional academic skills.

Social determinants of neurocognitive and academic performance in sickle cell disease.

Sickle cell disease (SCD) is associated with poor neurocognitive outcomes due to biomedical and psychosocial factors. The aims of this study were to investigate associations between household and neighborhood socioeconomic status (SES) with cognitive and academic outcomes in SCD and to determine if these relationships were modified by sickle genotype, fetal hemoglobin, or age. We prospectively recruited patients to complete a battery of neurocognitive and academic measures. Household SES was measured using the Barratt Simplified Measure of Social Status, a composite index of parent education and occupation. The Social Vulnerability Index was used to classify individuals based on social vulnerabilities at the neighborhood level. Overall, 299 patients between the ages of 4 and 18 (mean = 11.4, standard deviation = 4.3) years diagnosed with SCD (57% SS/SB0 -thalassemia) completed testing. Stepwise multivariate models demonstrated that patients with low social vulnerability (i.e., high SES) at the neighborhood level displayed intelligence and math scores that were 4.70 and 7.64 points higher than those living in areas with moderate social vulnerability, respectively (p < .05). Reading performance did not differ based on neighborhood SES; however, the effect of neighborhood SES was dependent on age, such that older participants living in neighborhoods with moderate or high levels of social vulnerability displayed poorer reading scores than those with low social vulnerability (p < .05). This study identified patients with SCD at higher risk of poor academic performance based on SES. Interventions addressing academic difficulties should be offered to all children with SCD, but should be emergently offered to this subpopulation.
