Multigroup latent class model of musculoskeletal pain combinations in children/adolescents: identifying high-risk groups by gender and age

Table 3 Membership and item response probabilities in gender-specific LCA modeling

	Gender	Latent class
	Gender	minor pain class	moderate pain class	major pain class
Class Membership Probabilities (%)	Girl	30.7%	57.9%	11.4%
Class Membership Probabilities (%)	Boy	34.5%	61.6%	4.0%
MSP
Neck pain	Girl	< 0.01 #	0.35	0.84
Neck pain	Boy	< 0.01	0.35	0.94
Shoulder pain	Girl	0.02	0.27	0.61
Shoulder pain	Boy	0.04	0.21	0.79
Upper back pain	Girl	< 0.01	0.25	0.50
Upper back pain	Boy	< 0.01	0.23	0.95
Low back pain	Girl	0.18	0.38	1.00
Low back pain	Boy	0.08	0.36	1.00

#: Rho estimates (item response probabilities) were presented. Considerable differences between boys and girls are shown in bold (≥ 0.1). Test the invariance across gender groups (Chi²_dif (12) = 16.76, P-value = 0.159)
