To examine the associations among early age of onset of sexual intercourse and drug use, lifetime and current problem drug behaviors, and sexual risk behaviors.
The 1993 Massachusetts Youth Risk Behavior Survey was administered to a sample of 3,054 students from randomly selected high schools and classrooms; 36% (1,078) consistently reported having had sexual intercourse. Three indicators of sexual risk behaviors were assessed: (1) number of lifetime sexual partners, (2) number of recent partners, and (3) condom nonuse at last intercourse. Three sets of independent variables were analyzed: (1) age of onset of sexual intercourse and drug use, (2) lifetime drug use, and (3) recent drug use.
Years of sexual intercourse, early age of onset of marijuana and cocaine use, lifetime frequency of marijuana, crack/freebase cocaine and alcohol use, and black race accounted for moderate amounts of the variation in the number of lifetime sexual partners. Years of sexual intercourse, early age of onset of marijuana use and cocaine use, lifetime frequency of crack/freebase and marijuana use, and recent use of cocaine, alcohol, and cigarettes accounted for smaller but significant amounts of the variation in the number of recent partners. Students more likely to report recent condom nonuse were older, females, had more years of sexual intercourse, had tried cocaine at a younger age, had used marijuana and cocaine more times (lifetime), and had more frequent recent use of marijuana.
Increased frequency and severity of drug use behaviors and more years of sexual intercourse are associated with an increased number of sexual partners and recent condom nonuse. These findings may guide history-taking and referral practices of health care providers. Programs designed to prevent sexually transmitted diseases and pregnancy should address drug use as well as sexual behavior.
研究初次性交年龄与药物使用、终生及当前的问题药物行为以及性风险行为之间的关联。
对从随机选取的高中及教室中抽取的3054名学生进行了1993年马萨诸塞州青少年风险行为调查；36%（1078名）的学生一直报告称有过性交经历。评估了三项性风险行为指标：（1）终生性伴侣数量，（2）近期性伴侣数量，以及（3）上次性交时未使用避孕套。分析了三组自变量：（1）初次性交年龄和药物使用年龄，（2）终生药物使用情况，以及（3）近期药物使用情况。
性交年限、大麻和可卡因使用的早发年龄、终生大麻、强效纯可卡因和酒精使用频率以及黑人种族，在一定程度上解释了终生性伴侣数量的差异。性交年限、大麻使用和可卡因使用的早发年龄、强效纯可卡因和大麻的终生使用频率，以及近期可卡因、酒精和香烟的使用，对近期性伴侣数量的差异解释较少但具有显著意义。更有可能报告近期未使用避孕套的学生年龄较大、为女性、性交年限更长、在更年轻时尝试过可卡因、（终生）使用大麻和可卡因的次数更多，以及近期大麻使用频率更高。
药物使用行为的频率和严重程度增加以及性交年限增加，与性伴侣数量增加和近期未使用避孕套有关。这些发现可能会指导医疗保健提供者的病史采集和转诊实践。旨在预防性传播疾病和怀孕的项目应同时关注药物使用和性行为。
