Multiple Regression
To examine whether healthcare utilization is a predictor of HRQOL in
youth with SCD, multiple regression analysis was deployed. There was a
statistically significant relationship observed between HRQOL and the
frequency of ER visits (B = -1.05, P = .04) and
hospitalizations (B = -2.73, P = .003) over the past 12
months (Table IV). There was also a relationship observed between age
and HRQOL in both regression models (P = .03).
