L’épidémie du sida parmi les usagers de drogues en Chine: 1995-2011

Alors que la prévalence du sida et le partage des seringues parmi les usagers de drogues injectables en Chine ont décliné et sont liés au développement national des programmes de réduction des risques, l’augmentation récente et rapide de la consommation de drogues en milieu festif présente un nouveau défi.

This study aimed to describe trends in the HIV epidemic among drug users (DUs) in China from 1995 to 2011.

The HIV epidemic among China's DUs is still highly concentrated in five provinces. Here, HIV prevalence peaked at 30.3% [95% confidence interval (CI) = 28.6, 32.1] among IDUs in 1999, and then gradually decreased to 10.9% (95% CI = 10.6, 11.2) by 2011. We observed a rapid increase in the use of ‘nightclub drugs’ among DUs from 1.3% in 2004 to 24.4% in 2011. A decline in recent needle sharing among current IDU from 19.5% (95% CI = 19.4, 19.6) in 2006 to 11.3% (95% CI = 11.2, 11.4) in 2011 was found to be correlated with the rapid scale-up of methadone maintenance treatment (MMT; r(4) = −0.94, P = 0.003) harm reduction efforts.

While HIV prevalence and needle sharing among current injecting drug users in China have declined dramatically and are correlated with the scale-up of national harm reduction efforts, the recent, rapid increased use of ‘nightclub drugs’ presents a new challenge.
