Swelogs (Swedish Longitudinal Gambling Study) epidemiological (EP-) track is a prospective study with four waves of data-collection among Swedish citizens aged 16-84 years at baseline. The major objectives of this track are to provide general population estimates of the prevalence and incidence of problem and at-risk gambling and enable comparisons with the first Swedish national study on gambling and problem gambling (Swegs) conducted in 1997/1998. The overall study (Swelogs) comprises three tracks of data collection; one epidemiological, one in-depth and one follow-up. It is expected to provide information that will inform the development of evidence-based methods and strategies to prevent the development of gambling problems. This paper gives an overview of the design of the epidemiological track, especially of its two first waves. The baseline wave, performed between October 2008 and August 2009, included 8165 subjects, of whom 6021 were re-assessed one year later. A stratified random sampling procedure was applied. Computer-supported telephone interviews were used as the primary method. Postal questionnaires were used to follow-up those not reached by telephone. The response rate was 55% in the first wave and 74% in the second. The interview and questionnaire data are supplemented by register data.
瑞典纵向赌博研究（Swelogs）的流行病学（EP-）追踪是一项前瞻性研究，对基线时年龄在16 - 84岁的瑞典公民进行四轮数据收集。该追踪的主要目标是提供一般人群中问题赌博和风险赌博的患病率和发病率估计，并能够与1997/1998年进行的瑞典第一项关于赌博和问题赌博的全国性研究（Swegs）进行比较。整个研究（Swelogs）包括三条数据收集路径；一条流行病学路径、一条深入研究路径和一条随访路径。预计该研究将提供信息，为制定预防赌博问题发展的循证方法和策略提供依据。本文概述了流行病学追踪的设计，特别是其前两轮。2008年10月至2009年8月进行的基线调查涵盖了8165名受试者，其中6021人在一年后接受了重新评估。采用了分层随机抽样程序。计算机辅助电话访谈被用作主要方法。邮寄问卷用于对未通过电话联系到的人进行随访。第一轮的回复率为55%，第二轮为74%。访谈和问卷数据由登记数据补充。
