Comorbidity, Pain, Utilization, and Psychosocial Outcomes in Older versus Younger Sickle Cell Adults: The PiSCES Project

Table 2

Pain-related variables (unadjusted means and standard errors).

Variable	Transition group (ages 16–25)	Younger adults (ages 26–36)	Older adults (ages 37–64)	value for overall ANOVA
% Pain days	32.7 (4.8)	62.4 (4.3)	64.7 (3.6)	<0.001
% Crisis days	8.4 (3.0)	18.3 (2.7)	17.0 (2.3)	0.033
Mean pain intensity
Pain days	4.2 (0.2)	4.3 (0.2)	4.4 (0.2)	0.687
Crisis days	5.6 (0.3)	5.4 (0.2)	5.5 (0.2)	0.867
Noncrisis pain days	3.8 (0.2)	3.9 (0.2)	4.1 (0.2)	0.451
Mean # body parts that hurt	2.4 (0.3)	3.2 (0.2)	3.6 (0.2)	0.001

Multiple comparisons (Bonferroni, Tukey): significant differences in unadjusted analyses, transition versus younger adults ; transition versus older adults ; younger versus older adults .
Mean pain intensity, measured on days when pain was reported, varies from 1 to 9, with higher values implying more pain.
