We then investigated potential LFU risk factors at inclusion through a case\u2013control study. Cases were 209 patients who had attended neither our clinic nor another HIV clinic for at least 1 year.

Independent risk factors for LFU were (i) year of enrolment before 1993 [odds ratio (OR) 6.7; 95% CI 2.7\u201316.5 versus after 1997]; (ii) year of enrolment between 1993 and 1997 (OR 5.1; 95% CI 2.0\u201313.0 versus after 1997); (iii) age&lt;30 years (OR 1.8; 95% CI 1.0\u20133.5 versus &gt;40 years); (iv) injecting drug use (OR 5.3; 95% CI 2.7\u201310.5 versus men who have sex with men); (v) homelessness and\/or illegal immigrant status (OR 2.2; 95% CI 1.0\u20134.9); and (vi) lack of a primary care provider (OR 6.0; 95% CI 2.4\u201315.1). A history of an AIDS\u2010defining illness (OR 0.3; 95% CI 0.2\u20130.6) and a history of psychiatric disease (OR 0.4; 95% CI 0.3\u20130.8) were both associated with a decreased risk of LFU.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study assessed the sociodemographic, clinical and behavioural characteristics associated with LFU in HIV\u2010infected patients.
