Although it is often assumed that drinking alcohol interferes with condom use, most studies on this topic do not meet the conditions required for causal interpretation. We examined the association of drinking to condom use using data from diaries of alcohol use and sexual encounters, collected over 8 weeks from college students and clients of a sexually transmitted disease clinic. This method establishes the temporal relationships between drinking and condom use and controls for individual differences by using a within-subjects analysis. Multilevel models that predicted condom use from alcohol use before the sexual encounter, partner type, and the use of other contraception showed that drinking before sex was unrelated to condom use. These results do not support the persistent notion that alcohol causes people to engage in sexual risk that they would avoid when sober; instead, people tend to follow their usual pattern of condom use, regardless of alcohol use.
尽管人们常常认为饮酒会妨碍避孕套的使用，但关于这一主题的大多数研究并不满足进行因果解释所需的条件。我们利用从大学生和一家性传播疾病诊所的客户那里收集的为期8周的饮酒和性接触日记数据，研究了饮酒与避孕套使用之间的关联。这种方法通过采用受试者内部分析来确定饮酒与避孕套使用之间的时间关系，并控制个体差异。从性接触前的饮酒情况、性伴侣类型以及其他避孕措施的使用情况来预测避孕套使用情况的多层次模型表明，性行为前饮酒与避孕套使用无关。这些结果并不支持饮酒会导致人们从事清醒时会避免的性风险这一长期存在的观念；相反，无论是否饮酒，人们往往会遵循他们通常的避孕套使用模式。
