Welsh Health Survey, 2009

The <i>Welsh Health Survey</i> (WHS) collects information about the health of people living in Wales, the way they use health services, and the factors that can affect their health. The current WHS series was commissioned by the Welsh Assembly Government (WAG), and carried out in both 2003-2004 and 2004-2005 by a consortium comprising the National Centre for Social Research (NatCen), Beaufort Research Limited, and the Department of Epidemiology and Public Health at University College London. In 2005-2006, NatCen had sole responsibility for conducting the survey and this has continued with the 2007, 2008 and 2009 surveys. <br>
<br>
The new WHS replaces two previous study series: the previous WHS, conducted in 1995 and 1998 (the 1998 WHS is held at the UK Data Archive under SN 4176), and the Health in Wales Survey which was conducted five times in 1985, 1988, 1990, 1993 and 1996 (none are currently held at the Archive). Users should note that results from the new WHS survey are not comparable with those from the previous surveys, because of differences in the questionnaires and survey methodology.<br>
<br>
The new WHS is 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.<br>
<br>
From 2007, more extensive survey elements for children were introduced than had been used for previous years of the WHS. Three age-specific questionnaires were used for children selected to participate in the survey. Two questionnaires were given to parents to complete on behalf of selected children aged 0 to 3, and selected children aged 4 to 12; a third questionnaire was given to selected children aged 13 to 15 to complete on their own behalf. In addition, interviewers were asked to take height and weight measurements of selected children aged between 2 and 15 years, if children and parents consented. Results from this survey are not comparable with those from the previous surveys because of differences in the questionnaires and survey methodology. <br>

For the third edition (April 2014), the adult data file and the user guide have been updated, due to the removal of one respondent's data.<br>

《威尔士健康调查》（Welsh Health Survey，WHS）收集威尔士居民的健康状况、医疗服务使用方式及影响健康因素的相关信息。当前WHS系列由威尔士议会政府（Welsh Assembly Government，WAG）委托，2003-2004年及2004-2005年的调查由英国国家社会研究中心（National Centre for Social Research，NatCen）、博福特研究有限公司（Beaufort Research Limited）与伦敦大学学院流行病学与公共卫生系组成的联盟实施。2005-2006年，NatCen独自承担调查职责，并延续至2007、2008及2009年的调查。

新版WHS替代了两个先前的研究系列：1995年及1998年开展的旧版WHS（1998年WHS数据由英国数据档案馆以SN 4176编号保存），以及1985、1988、1990、1993及1996年五次开展的《威尔士健康状况调查》（Health in Wales Survey）（目前该调查数据未在档案馆保存）。用户需注意，由于问卷与调查方法存在差异，新版WHS的结果与先前调查结果不具可比性。

新版WHS旨在：
• 提供健康状况、健康决定因素及医疗服务使用情况的评估数据
• 助力健康战略与国家服务框架中目标及指标的设定与监测
• 分析不同人群亚组（如性别、年龄、社会阶层）及地区间的差异
• 为威尔士国民健康服务（National Health Service）的资源分配提供医疗需求的直接测量依据
• 为地方卫生委员会及地方政府层面制定联合健康、社会关怀与福祉战略提供信息支持

WHS基于威尔士私人住户中16岁及以上成年人的代表性样本。此外，每户随机选取至多两名0-15岁儿童参与调查。

自2007年起，WHS引入了比往年更全面的儿童调查内容。针对入选儿童采用了三种按年龄划分的问卷：0-3岁及4-12岁儿童的问卷由家长代为填写；13-15岁儿童的问卷由其自行填写。此外，若儿童及家长同意，调查员将对2-15岁入选儿童进行身高与体重测量。由于问卷与调查方法存在差异，本次调查结果与先前调查结果不具可比性。

针对第三版（2014年4月），因移除了一名受访者的数据，成人数据文件及用户指南已完成更新。
