National Survey of Sexual Attitudes and Lifestyles, 2000-2001

<p>The British <i>National Surveys of Sexual Attitudes and Lifestyles (</i>Natsal) have been undertaken decennially since 1990 and provide a key data source underpinning sexual and reproductive health (SRH) policy.</p><p> Further information is available from the <a class="external" href="https://www.natsal.ac.uk/" title="Natsal" style="">Natsal</a> website.<br>

</p> The <i>National Survey of Sexual Attitudes and Lifestyles, 2000-2001</i> (Natsal-2) was very closely modelled on the Natsal-1, carried out by the same team of investigators. The results from the first survey were widely used by academics and policymakers. Towards the end of the 1990s, it became increasingly clear that the Natsal-1 results were growing outdated and that repeat measures were needed not only to provide up-to-date information for estimating the likely extent of the HIV epidemic in Britain, but also to look at behaviour change over time and to include new questions to take account of current information needs in the field of sexual health.<br>
<br>
The main objectives of Natsal-2 were to:<ul><li>provide a detailed understanding of patterns of sexual behaviour in Britain (including for example, numbers of sexual partners, frequency of different sexual practices, and homosexual experience)</li><li>provide data for HIV/AIDS projections in Britain</li><li>assess whether there have been changes in behaviour since Natsal-1</li><li>measure the prevalence of <i>chlamydia trachomatis</i> infection, via urine samples</li></ul>Given the importance of making comparisons with Natsal-1 data, Natsal-2 was largely a repeat of the 1990 survey. However, it was also recognised that a number of methodological developments in survey research in the intervening period could lead to improvements in the data collection process for Natsal-2. In particular, the use of Computer Assisted Personal Interview (CAPI) and Computer Assisted Self-Interview (CASI) techniques had the potential to improve on response rates and data quality, as well as maximise the disclosure of sensitive behaviours.<br>
<br>
Along with the changes in methodology, there were a number of other differences between Natsal-1 and 2:<ul><li>Natsal-2 covered a younger age group (ages 16-44) than Natsal-1 (16-59) in order to focus survey resources on a group greater at risk</li><li>people living in the Greater London area were purposely over-sampled</li><li>a boost sample of people from four ethnic minority groups - Black Caribbean, Black African, Indian and Pakistani - was included</li><li>new question modules were introduced on, for example, partnership formation, sexual mixing abroad, preferred sources of contraception and advice, history of sexually transmitted infections, and sexual dysfunction</li><li>a urine specimen was collected from consenting respondents, to test for <i>chlamydia trachomatis</i></li></ul><br>

<p>英国<i>《性态度与生活方式全国调查》（Natsal）</i>自1990年起每十年开展一次，是支撑性与生殖健康（SRH）政策的关键数据来源。</p><p>更多信息可从<a class="external" href="https://www.natsal.ac.uk/" title="Natsal">Natsal</a>网站获取。<br><br></p>《2000-2001年性态度与生活方式全国调查》（Natsal-2）在很大程度上以Natsal-1为蓝本，由同一研究团队开展。Natsal-1的结果被学术界和政策制定者广泛采用。到20世纪90年代末，Natsal-1的结果逐渐过时，因此需要重复开展调查：不仅为估算英国HIV流行的可能规模提供最新信息，还需考察行为随时间的变化，并纳入新问题以满足性健康领域当前的信息需求。<br><br>Natsal-2的主要目标包括：<ul><li>深入了解英国人群的性行为模式（例如性伴侣数量、不同性行为的频率及同性恋经历）</li><li>为英国HIV/AIDS流行趋势预测提供数据</li><li>评估自Natsal-1以来性行为是否发生变化</li><li>通过尿液样本测量<i>沙眼衣原体（chlamydia trachomatis）</i>感染的患病率</li></ul>鉴于与Natsal-1数据进行比较的重要性，Natsal-2在很大程度上是1990年调查的重复。然而，研究人员也认识到，在此期间调查研究方法的多项进展可改进Natsal-2的数据收集过程。特别是计算机辅助个人访谈（Computer Assisted Personal Interview，简称CAPI）和计算机辅助自填访谈（Computer Assisted Self-Interview，简称CASI）技术，有望提高应答率和数据质量，并最大限度地披露敏感行为。<br><br>除方法学变化外，Natsal-1与Natsal-2之间还有其他若干差异：<ul><li>Natsal-2的调查年龄组（16-44岁）比Natsal-1（16-59岁）更年轻，以将调查资源集中在风险更高的人群上</li><li>对大伦敦地区居民进行了有意过度抽样</li><li>纳入了来自四个少数族裔群体的补充样本：加勒比黑人、非洲黑人、印度裔和巴基斯坦裔</li><li>新增了若干问题模块，例如伴侣关系建立、境外性接触、首选避孕方式及咨询来源、性传播感染史和性功能障碍等</li><li>从同意参与的受访者中收集尿液样本，用于检测<i>沙眼衣原体（chlamydia trachomatis）</i></li></ul><br>
