Social Environment and Biomarkers of Aging Study (SEBAS)
SEBAS is a nationally representative longitudinal survey of Taiwanese middle-aged and older adults. It adds the collection of biomarkers and performance assessments to the Taiwan Longitudinal Study of Aging (TLSA), a nationally representative study of adults aged 60 and over, including the institutionalised population. The TLSA began in 1989, with follow-ups approximately every 3 years. The first wave of SEBAS, based on a sub-sample of respondents from the 1999 TLSA, was conducted in 2000. A total of almost 1,500 respondents completed a face-to-face home interview. A follow-up study was fielded between August 2006 and the end of January 2007, using a protocol similar to the 2000 SEBAS.
