Because of the high prevalence of marijuana smoking in Jamaica, it is important to know if this practice is associated with increased risk for STD infections. A national sample of 2 580 randomly selected Jamaicans, aged 15 to 49 years were administered a questionnaire to measure a number of health and behavioural variables. The results indicated that more persons who smoked marijuana before sex had a history of STD infections than non-marijuana smokers, the difference was significant among men (46% vs 26%, p < 0.001) but not among women (19% vs 8%, p = 0.09). There was no difference in age, however, more of the smokers were unmarried, poorly educated and unemployed than persons who did not smoke marijuana before sex. They were also more likely to engage in high risk sex behaviours and other risk taking behaviors than non-smokers. The results of multiple logistic regression analyses indicated that marijuana smoking before sex was an independent risk factor for STDs among men (Odds Ratio = 2.0, p = 0.04). Although it was not possible to determine if the association was causal, the increased risk for STDs among men who smoke marijuana before sex should be incorporated into the Jamaican STD/AIDS control programme by making special efforts to encourage condom use among marijuana smokers.
由于牙买加吸食大麻的现象非常普遍，了解这种行为是否会增加性传播感染的风险就显得尤为重要。对2580名年龄在15至49岁之间、随机抽取的牙买加人进行了全国性抽样调查，并向他们发放问卷以测量一系列健康和行为变量。结果显示，在性行为前吸食大麻的人中，有性传播感染病史的人比不吸食大麻的人更多，这种差异在男性中显著（46%对26%，p<0.001），但在女性中不显著（19%对8%，p = 0.09）。在年龄方面没有差异，然而，与在性行为前不吸食大麻的人相比，更多的吸食者未婚、受教育程度低且失业。他们也比不吸烟者更有可能从事高风险性行为和其他冒险行为。多元逻辑回归分析结果表明，在性行为前吸食大麻是男性感染性传播疾病的一个独立危险因素（比值比 = 2.0，p = 0.04）。尽管无法确定这种关联是否具有因果关系，但对于在性行为前吸食大麻的男性，其感染性传播疾病风险的增加应纳入牙买加性传播感染/艾滋病控制计划，为此应做出特别努力，鼓励吸食大麻者使用避孕套。
