HIV infection and tobacco smoking behaviour: prospects for prevention? ANRS CO3 Aquitaine Cohort, 2002.

OBJECTIVE: To provide up-to-date and covariate-specific estimates on tobacco smoking prevalence in a representative cohort of French human immunodeficiency virus (HIV) 1 infected patients in 2002.
DESIGN: We conducted a cross-sectional analysis of the Aquitaine Cohort of HIV-infected patients. A logistic regression model was used to estimate associations between regular tobacco smoking and sex, age, HIV transmission categories, duration and immuno-virological status of HIV infection and duration of antiretroviral therapy. Smoking prevalence estimates were compared with the general French population values after stratification on age and sex.
RESULTS: Among 2036 patients included in the analysis, 51% were regular smokers (95%CI 49-53). Smoking prevalence was significantly higher with younger age (OR 1.7 among those < or = 45 years of age), among injecting drug users (OR 4.3), among those whose infection was not controlled (OR 1.2) and those whose HIV infection had been diagnosed for > or = 5 years (OR 1.5). The main difference with the general population was the peak smoking prevalence among HIV-positive patients infected through injecting drug use.
CONCLUSIONS: HIV-infected patients are highly exposed to tobacco smoking, which is implicated in multiple conditions occurring in the course of HIV infection. Adapted smoking cessation programmes should become one of the priorities of the medical care of HIV-infected individuals.
