Incidence and determinants of acute stress disorder after supracondylar humeral fracture surgery in school-age children

Table 9 Multivariate logistic regression analysis of factors influencing acute stress disorder

Influencing factor	B	SE	Wald	P value	aOR	95%CI
Fracture type			7.896	0.019
Type II vs type I	0.892	0.457	3.814	0.051	2.44	0.99-6.00
Type III vs type I	1.347	0.482	7.805	0.005	3.85	1.50-9.88
Pain intensity (per 1-point increase)	0.234	0.067	12.125	< 0.001	1.26	1.11-1.44
Postoperative complications (present vs absent)	0.987	0.358	7.608	0.006	2.68	1.33-5.41
Previous trauma history (present vs absent)	0.756	0.318	5.647	0.017	2.13	1.14-3.98
Family support status (per 1-point increase)	-0.048	0.014	11.689	0.001	0.95	0.93-0.98
Constant	0.125	1.246	0.010	0.920	1.13

Excluded variables and reasons: (1) Family structure and family economic status were excluded due to P > 0.10 in multivariate analysis; (2) Residence was excluded due to collinearity with family economic status; and (3) Coping strategy efficacy and effectiveness total scores had collinearity with family support status, so family support status with larger effect size was selected for the model. aOR: Adjusted odds ratio; CI: Confidence interval.
