To identify characteristics of women reporting multiple sexual partners and early age at first intercourse in Italy.
Information on 1139 control women (median age 54 years) interviewed as part of a case-control study of cervical neoplasia conducted in the greater Milan area, Northern Italy were analysed using stratified analysis and multiple logistic regression.
Overall, 81% of the study sample reported no more than one sexual partner, 10% two and 9% three or more. The proportion reporting multiple sexual partners tended to be higher among younger and more educated women (4% vs 19% of women with respectively less than 7 and 12 or more years of education reported three or more partners). Ever smokers reported a higher number of sexual partners than never smokers. The proportion of nulliparae reporting three or more sexual partners was higher than that of parous women. These findings were confirmed after taking into account in a multivariate analysis the role of potential confounding factors. Furthermore similar findings emerged from an analysis restricted to women aged 40 years or less. Always considering number of sexual partners, no relationship emerged with marital status, spontaneous or induced abortions, lifetime number of reported Pap smears and contraceptive habits. With reference to age at first intercourse, 25% of the study population reported their first intercourse at age 18 or before, 34% between 19 and 22 years, and 41% at age 23 or later. Younger women (that is, more recent cohorts) more frequently reported earlier age at first intercourse and the proportion of never married women reporting early intercourse was higher (51% vs 22% of never married vs married women). No relationship emerged between education, smoking habits, parity, history of spontaneous or induced abortions, number of Pap smears, contraceptive habits, and age at first intercourse.
This study documents conservative sexual habits in Northern Italian females (at least on the basis of self reporting) but indicates that any educational compaigns towards safe sex should be focused towards younger women, particularly smokers, unmarried and nulliparae.
确定意大利报告有多个性伴侣及初次性交年龄较小的女性的特征。
对作为意大利北部米兰大区一项宫颈癌病例对照研究一部分而接受访谈的1139名对照女性(中位年龄54岁)的信息进行分层分析和多因素逻辑回归分析。
总体而言,81%的研究样本报告性伴侣不超过一名,10%报告有两名,9%报告有三名或更多。报告有多个性伴侣的比例在年轻和受教育程度较高的女性中往往更高(受教育年限分别少于7年和12年或以上的女性中,报告有三名或更多性伴侣的比例分别为4%和19%)。曾经吸烟者报告的性伴侣数量多于从不吸烟者。未生育女性中报告有三名或更多性伴侣的比例高于已生育女性。在多因素分析中考虑潜在混杂因素的作用后,这些发现得到了证实。此外,在对40岁及以下女性进行的分析中也出现了类似的发现。始终考虑性伴侣数量,未发现与婚姻状况、自然流产或人工流产、报告的巴氏涂片检查次数和避孕习惯之间存在关联。关于初次性交年龄,25%的研究人群报告初次性交年龄在18岁或之前,34%在19至22岁之间,41%在23岁或之后。年轻女性(即较新的队列)更频繁地报告初次性交年龄较早,未婚女性中报告初次性交年龄较早的比例更高(未婚女性为51%,已婚女性为22%)。在教育程度、吸烟习惯、生育情况、自然流产或人工流产史、巴氏涂片检查次数、避孕习惯和初次性交年龄之间未发现关联。
本研究记录了意大利北部女性保守的性行为习惯(至少基于自我报告),但表明任何关于安全性行为的教育活动都应针对年轻女性,特别是吸烟者、未婚女性和未生育女性。
