National Survey of Sexual Attitudes and Lifestyles, 2010-2012: Secure Access

<P>Abstract copyright UK Data Service and data collection copyright owner.</P>The <i>British National Surveys of Sexual Attitudes and Lifestyles</i>, or Natsal, are among the largest and most detailed studies of sexual behaviour in the world. Three Natsal surveys have taken place to date: Natsal-1 in 1990-1991 (available from the UK Data Archive under SN 3434), Natsal-2 in 1999-2001 (available under SN 5223) and Natsal-3 in 2010-2012 (available under SN 7799, and for Secure Access versions SN 8178 and SN 8179). Further information is available from the <a class="external" href="http://www.natsal.ac.uk/home.aspx" title="Natsal">Natsal</a> website.<br><br>The <i>National Survey of Sexual Attitudes and Lifestyles, 2010-2012</i> is the third survey in the series. Natsal-3 aimed to provide up-to-date information on key sexual behaviours and risk factors, as well as to look at trends over time by including comparable measures to those used in the previous two surveys, and to include new questions and an extended age range to take account of current information needs in the field of sexual health. <br>
<br>
The main objectives of Natsal-3 were to: <ul><li>provide a detailed understanding of patterns and variability of sexual behaviour in Britain (including, for example, numbers of sexual partners, frequency of different sexual practices, and homosexual experience) </li><li>provide self-reported estimates of a range of sexual and reproductive health outcomes (including, for example, pregnancy, STI diagnosis, contraception use) and health service use</li><li>explore sexual behaviour and function over the life-course by including an older age group (up to age 74) </li><li>describe changes in sexual activity over time and trends in relationships, reproductive history and patterns of fertility (using Natsal-1, Natsal-2 and Natsal-3) </li><li>from urine samples, measure the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, type-specific Human Papillomavirus, HIV antibody and Mycoplasma genitalium</li><li>measure the gender-specific distribution of salivary testosterone and its relationship to sexual behaviour, function and ageing</li></ul><b>Secure Access Datasets</b><br>
The Natsal-3 Secure Access datasets include additional variables considered too sensitive or disclosive for release under standard End User Licence (EUL) conditions. Additional variables available in the Secure Access studies (SNs 8178 and 8179) include:<ul><li>detailed geographic variables, including Local Authority Districts and Area Classification for Output Areas Subgroups</li><li>respondent month of birth</li><li>age when had hysterectomy</li><li>month and year of first and most recent sex with partners</li><li>outcomes of pregnancies</li><li>age at first stillbirth</li><li>variables relating to abortions</li><li>age at miscarriage, abortion or still birth</li><li>month of last pregnancy</li><li>genders and month of birth of children</li><li>number of children gave birth to in multiple births</li><li>ungrouped ethnic group</li><li>age when first and last injected non-prescribed drugs</li><li>dates (months) relating to live-in partners</li><li>qualifications</li><li>Indices of Multiple Deprivation</li></ul>The other Secure Access dataset Natsal-3 dataset, SN 8179 (National Survey of Sexual Attitudes and Lifestyles, 2010-2012: Biological Data: Secure Access) includes all the variables listed above, plus variables relating to urine and saliva sample tests.<br>
<br><br><B>Main Topics</B>:<BR><br>The face-to-face interview included sections on: general health; alcohol consumption; smoking; body mass index; family history; learning about sex; first sexual experiences; contraception; periods and menopause; household classification; previous live-in partnerships; household composition; employment; qualifications; parents occupation; ethnicity; sexual identity; religion and internet access.<br>
<br>
The self-completion questionnaire included sections on: heterosexual behaviour; same-sex behaviour; heterosexual partnerships; same-sex partnerships; overlapping partnerships; online partnerships; total partnerships; detailed partnerships; travel and sex abroad; non-consensual sex; paying for sex; pregnancy history; unplanned pregnancy; family formation; fertility intentions and infertility; sexually transmitted infections; HIV testing; sexual function; drug use; mood and wellbeing and circumcision.<br>

英国全国性态度与生活方式调查（British National Surveys of Sexual Attitudes and Lifestyles，简称Natsal）是全球规模最大、内容最详尽的性行为研究项目之一。截至目前，该系列已开展三轮调研：1990-1991年的Natsal-1（可通过英国数据档案馆以编号SN 3434获取）、1999-2001年的Natsal-2（编号SN 5223），以及2010-2012年的Natsal-3（编号SN 7799，其安全访问版本编号为SN 8178与SN 8179）。更多信息可访问Natsal官方网站：http://www.natsal.ac.uk/home.aspx。

2010-2012年的全国性态度与生活方式调查是该系列的第三轮调研（Natsal-3）。该项目旨在提供关键性行为与风险因素的最新信息，通过沿用前两轮调研的可比测量指标追踪长期趋势，同时新增调研问题并拓展年龄范围，以适应当前性健康领域的信息需求。

Natsal-3的核心目标包括：
- 深入解析英国民众性行为的模式与个体差异（例如性伴侣数量、不同性行为的发生频次、同性性经历等）
- 提供一系列性行为与生殖健康结局的自我报告估算值（例如妊娠、性传播感染诊断、避孕措施使用情况）及医疗服务使用数据
- 通过纳入74岁及以上的高龄群体，探究整个人生周期中的性行为与性功能变化
- 结合Natsal-1、Natsal-2与Natsal-3的调研数据，描述性行为随时间的变化趋势，以及伴侣关系、生殖史与生育模式的演变
- 通过尿液样本检测沙眼衣原体（Chlamydia trachomatis）、淋病奈瑟菌（Neisseria gonorrhoeae）、分型人乳头瘤病毒（Human Papillomavirus）、HIV抗体以及生殖支原体（Mycoplasma genitalium）的感染率
- 测量唾液睾酮的性别特异性分布特征，及其与性行为、性功能和衰老的关联
