Prevalence and Characteristics of Chemsex: A Cross-Sectional Observational Study.

Introduction: Chemsex has been defined until now as the use of specific psychoactive substances during sexual activities in men who have sex with men (MSM) contexts to facilitate, enhance, and prolong the experience. Many studies have investigated this phenomenon in specific communities, such as MSM, or have explored the risk of sexually transmitted diseases (STDs). The objective of this study was to investigate the prevalence of chemsex in an Italian group and describe its main characteristics.

At-risk gambling in patients with severe psychiatric illness and in community subjects matched for age and sex.

In the recent literature the rates of gambling in psychiatric patients have been compared only indirectly with those found in community samples and no study has so far matched a clinical sample with community controls. We selected 875 outpatients attending two community mental health centers and 3.500 community subjects, matched for age and sex.
