Background: Night recreational settings have become a key location for the socialisation of young people. For customers attending these places, the consumption of alcohol and drugs is related to changes in sexual decision making and associated with increased likelihood of engagement in more risky sexual behaviours. Aim: To identify the characteristics of Portuguese young people who attend nightclubs, pubs and bars; to explore relationships between attendance at these settings and the consumption of alcohol and drugs; to study associations between substance use and sexual behaviour. Methods: Respondent-driven sampling methodology was used in nine Portuguese cities to survey 1142 young people who attend nightlife leisure locations. Results: Respondents regularly go out at night, especially at weekends. The most used substances are alcohol, cannabis, cocaine and ecstasy. Alcohol and drugs users have more regular and deeply-rooted night recreation habits than nonusers and drugs consumption increases with increased recreational activities. In the last 12 months, 83.3% of the respondents have already had sexual intercourse (X = 2.0 partner; SD = 2.3), 51.0% had sex under the influence of alcohol, 22.9% under the influence of drugs and 46.7% agreed that this influence made them have unsafe sex. Early alcohol and drug use was proportionately related to an early sexual experience. Alcohol and drugs users were more likely to adopt more sexual risk behaviours than non-users. Conclusions: The enjoyment of recreational nightlife settings exposes Portuguese clubbers to environmental factors which, in combination with substance use, may influence the nature of relationships between alcohol and drug use and sexual behaviour.Key words: nightlife recreational settings, alcohol, drug use, sexual behaviour.
RESUMEN ABSTRACTAntecedentes: Los ambientes recreativos nocturnos son lugares claves de la socialización de los jóvenes. Entre quienes frecuentan estos lugares, el consumo de alcohol y drogas provoca cambios en la toma de decisiones sobre relaciones sexuales y se asocia a una mayor probabilidad de practicar conductas sexuales de riesgo. Objetivo: Describir a los jóvenes que salen los fines de semana; analizar las relaciones entre el hecho de ir a dichos lugares y el consumo de alcohol y drogas; estudiar asociaciones entre consumo de sustancias y conductas sexuales. Métodos: Se utilizó la metodología del respondent-driven sampling (o muestreo dirigido por los entrevistados) en nueve ciudades portuguesas para interrogar a 1.142 jóvenes que asistieron a locales de ocio nocturno. Resultados: Los participantes salen habitualmente de noche, sobre todo los fines de semana. Las sustancias más consumidas fueron alcohol, cannabis, cocaína y éxtasis. Los consumidores de alcohol y drogas presentan hábitos recreativos nocturnos mucho más arraigados que los no consumidores, y el consumo de drogas aumenta en proporción a las actividades recreativas. En los últimos 12 meses el 83,3% de los entrevistados habían mantenido relaciones sexuales ( X ...
