The number of sexual partners has in studies been shown to be a factor correlated with STI but there is little published knowledge on what factors are associated with number of sexual partners.
To examine which variables are correlated with the number of lifetime sexual partners (NLSP) among youths.
All 18-year old girls and boys in four cities in northern Sweden.
A population-based study where participants answered a questionnaire regarding their social lifestyle, psychological and sexual health. The associations between these independent variables and the dependent variable (NLSP) were investigated by multivariate linear regression analysis.
The boy and girl median NLSP was 2.0 (P25 =1.0, P75=3.0). The final model explained 29% of the total boy NLSP variation and 46% of the total girl NLSP variation. Eight boy variables and thirteen girl variables significantly correlated with NLSP were found. The two strongest variables associated with increased NLSP among boys and girls, was feelings of guilt or shame after sex and smoking regularly. Variables prior associated with an increased risk of acquiring STI's were associated with increased NLSP. The study found new gender differed behaviour variables correlated to NLSP not previously considered to be risk factors for STI.
To prevent the spread of STI it is important that persons with many partners are identified, treated if necessary and possible, or encouraged to change their behaviour. The study found several boy and girl variables associated with increased NLSP, which could facilitate both primary- and secondary preventions.
研究表明性伴侣数量是与性传播感染相关的一个因素，但关于哪些因素与性伴侣数量相关的公开知识却很少。
研究哪些变量与青少年一生中性伴侣的数量（NLSP）相关。
瑞典北部四个城市所有18岁的女孩和男孩。
一项基于人群的研究，参与者回答了一份关于他们社会生活方式、心理和性健康的问卷。通过多元线性回归分析研究这些自变量与因变量（NLSP）之间的关联。
男孩和女孩的NLSP中位数为2.0（P25 = 1.0，P75 = 3.0）。最终模型解释了男孩NLSP总变异的29%和女孩NLSP总变异的46%。发现了八个与男孩NLSP显著相关的变量和十三个与女孩NLSP显著相关的变量。在男孩和女孩中，与NLSP增加相关的两个最强变量是性行为后的内疚或羞耻感以及经常吸烟。先前与感染性传播感染风险增加相关的变量与NLSP增加相关。该研究发现了与NLSP相关的新的性别差异行为变量，这些变量以前未被认为是性传播感染的危险因素。
为了预防性传播感染的传播，识别有多个性伴侣的人、在必要和可能的情况下进行治疗或鼓励他们改变行为非常重要。该研究发现了几个与NLSP增加相关的男孩和女孩变量，这有助于一级和二级预防。
