背景数据来自1990-1991年（Natsal-1）和1999-2001年（Natsal-2）进行的前两次全国性态度和生活方式调查，在过去的二十年里，这些数据被广泛用于为英国的性健康政策提供信息。Natsal-3于2010年9月至2012年8月进行，以提供最新的性生活方式措施，并通过纳入老年组来扩大先前研究的范围（长达74年），一个扩展范围的主题和生物措施。方法我们描述的方法在Natsal-3，结果共完成15162次访谈，应答率为57.7%，合作率为65.8%。年龄在16- 34岁之间的加强样本的应答率为64.8%，仅略低于调查类似年龄范围（16-44岁）的Natsal-2的65.4%。数据按年龄、性别和地区加权，以减少可能的偏差。与人口普查数据的比较表明，加权样本在一系列受访者特征方面具有良好的代表性。面试包括面对面和自我完成两个部分，都是在电脑上进行的。来自4550名年龄在16- 44岁之间的有性经验的参与者的尿液样本进行了一系列性传播感染的检测。唾液样本从4128名参与者年龄在18- 74 years进行了testosterone.Conclusions Natsal-3提供了一个高质量的数据集，可用于检查在过去的20 years的性态度和行为的趋势。
Background Data from the first two National Surveys of Sexual Attitudes and Lifestyles, carried out in 1990-1991 (Natsal-1) and 1999-2001 (Natsal-2), have been extensively used to inform sexual health policy in Britain over the past two decades. Natsal-3 was carried out from September 2010 to August 2012 in order to provide up-to-date measures of sexual lifestyles and to extend the scope of the previous studies by including an older age group (up to 74years), an extended range of topics and biological measures.Methods We describe the methods used in Natsal-3, which surveyed the general population in Britain aged 16-74years (with oversampling of younger adults aged 16-34years).Results Overall, 15162 interviews were completed, with a response rate of 57.7% and a cooperation rate of 65.8%. The response rate for the boost sample of ages 16-34years was 64.8%, only marginally lower than the 65.4% achieved for Natsal-2, which surveyed a similar age range (16-44). The data were weighted by age, gender and region to reduce possible bias. Comparisons with census data show the weighted sample to provide good representation on a range of respondent characteristics. The interview involved a combination of face-to-face and self-completion components, both carried out on computer. Urine samples from 4550 sexually-experienced participants aged 16-44years were tested for a range of STIs. Saliva samples from 4128 participants aged 18-74years were tested for testosterone.Conclusions Natsal-3 provides a high quality dataset that can be used to examine trends in sexual attitudes and behaviours over the past 20years.
