Welsh Health Survey, 2014: Special Licence Access

<P>Abstract copyright UK Data Service and data collection copyright owner.</P><i>Background to the series</i><br>
The <i>Welsh Health Survey</i> (WHS), which ran from 1995-1998 and then from 2003/04-2015, collected information about the health of people living in Wales, the way they use health services, and the factors that can affect their health. The WHS ceased in 2015. From April 2016 health and health related lifestyles are reported on using the <a href="https://discover.ukdataservice.ac.uk/series/?sn=2000035" title="National Survey for Wales">National Survey for Wales</a>. <br>
<br>
The first two survey years (1995, not held at the UK Data Archive, and 1998 (SN 4176))were carried out by a consortium comprising the National Centre for Social Research (now NatCen Social Research), Beaufort Research Limited, and the Department of Epidemiology and Public Health at University College London. From 2005/06 onwards, NatCen Social Research had sole responsibility for conducting the survey. For further details, see documentation. <br>
<br>
<i>Aims of the WHS:</i><br>
The WHS was designed to:<ul><li>provide estimates of health status, health determinants and health service use</li><li>contribute to setting and monitoring targets and indicators in the health strategies and National Service Frameworks</li><li>examine differences between population subgroups (such as sex, age, social class) and local areas</li><li>provide a direct measurement of need for health care for National Health Service resource allocation in Wales</li><li>provide local health board- and local authority-level information for the development of joint local health, social care and well-being strategies</li></ul>The WHS is based on a representative sample of adults aged 16 and over living in private households in Wales. In addition, up to two children aged 0 to 15 were randomly selected from each household. For further details, see documentation.<br>
<br>
<i>Differences between the standard access End User Licence version and the Special Licence access version:</i><br>
The standard access End User Licence WHS does not include unitary authority, strata and PSU as these variables pose a potential risk of disclosure. These variables are included in the Special Licence access versions from 2003/04 onwards. For further information on how to make an application for the Special Licence data, see the ACCESS section.<br>

<br><br>The current WHS replaced two previous surveys; the former <i>Welsh Health Survey</i> (undertaken in 1995 and 1998) and the former <i>Health in Wales Survey</i> (undertaken every two to three years between 1985 and 1996). Results from this survey are not comparable with those from the previous surveys because of differences in the questionnaires and survey methodology.<br>
<br>
The Special Licence data provides users access to Unitary Authorities and was designed to be used with the standard data for that year. The EUL version of the WHS 2014 is held at the UK Data Archive under SN 7841.<br>

## 系列研究背景
威尔士健康调查（Welsh Health Survey, WHS）分别于1995-1998年及2003/04-2015年开展，旨在收集威尔士居民的健康状况、医疗服务使用情况及健康影响因素相关信息。该调查于2015年终止，2016年4月起，威尔士全国调查（National Survey for Wales）开始发布健康及健康相关生活方式相关报告。

1995年（未存入英国数据档案库）与1998年（存档编号SN 4176）的前两个调查年度，由国家社会研究中心（National Centre for Social Research，现简称为NatCen Social Research）、博福特研究有限公司（Beaufort Research Limited）及伦敦大学学院流行病学与公共卫生系组成的联盟负责实施。2005/06年度起，NatCen Social Research独家承担调查执行工作。更多细节请参阅相关文档。

## 威尔士健康调查的研究目标
本调查旨在达成以下目标：
- 提供健康状况、健康决定因素及医疗服务使用情况的量化估算值
- 助力健康战略与国家服务框架中目标与指标的制定与监测
- 探究人口亚组（如性别、年龄、社会阶层）及不同地区间的健康差异
- 直接评估威尔士境内英国国民保健服务（National Health Service, NHS）的医疗资源配置需求
- 为各地方卫生委员会及地方当局制定联合地方卫生、社会护理与福祉战略提供区级层面的信息支持

威尔士健康调查的样本为威尔士境内居住于私人家庭的16岁及以上成年人群代表性样本，此外从每个家庭中随机选取至多2名0至15岁的儿童。更多细节请参阅相关文档。

## 标准访问终端用户许可版与特殊许可访问版的差异
标准访问终端用户许可（End User Licence, EUL）版威尔士健康调查数据未包含单一行政区（Unitary Authority）、分层变量及初级抽样单元（Primary Sampling Unit, PSU），因上述变量存在潜在的身份披露风险。2003/04年度起的特殊许可访问版数据包含上述变量。如需申请特殊许可数据，请参阅“访问”章节获取详细信息。

本系列调查替代了两项既往调研：1995年与1998年开展的原威尔士健康调查，以及1985年至1996年间每2至3年开展一次的原《威尔士健康状况调查（Health in Wales Survey）》。由于问卷设计及调查方法存在差异，本次调查结果与既往调研结果不具有可比性。

特殊许可数据提供了单一行政区访问权限，其设计目的是与对应年度的标准数据配合使用。2014年威尔士健康调查的终端用户许可版数据存档于英国数据档案库，存档编号为SN 7841。

## 核心主题
2014年特殊许可版威尔士健康调查数据涵盖的核心主题包括：
- 单一行政区及对应调查年度与受访者的唯一序列编号。

可与存档编号SN 7841下的标准（终端用户许可版）威尔士健康数据进行关联的特殊许可数据集。
