Risk factors for S. aureus colonization*	Prevalence ratio (95% CI)	P value†
Age (years)
16–28	Reference
29–42	1·02 (0·82–1·27)	0·85
⩾ 43	0·76 (0·58–0·98)	0·04

CI, Confidence interval; MRSA, methicillin-resistant Staphylococcus aureus; MSSA, methicillin-sensitive Staphylococcus aureus.

^*Only significant findings are presented here. The adjusted multivariable regression model also included shared personal items, skin infection within the past 6 months, and social group membership.
