The first wave of SEBAS, based on a sub-sample of respondents from the 1999 Taiwan Longitudinal Study of Aging (TLSA), was conducted in 2000 and represented a national sample of Taiwanese adults aged 54 and older. A total of 1023 respondents completed both a face-to-face home interview and, several weeks later, a hospital-based physical exam. In addition to a 12-hour (7pm-7am) urine specimen collected the night before the exam and a fasting blood specimen during the exam, trained staff measured blood pressure, height, weight, waist, and hip circumference. A second wave of SEBAS was conducted in 2006 using a similar protocol to SEBAS 2000, but with the addition of performance assessments conducted by the interviewers at the end of the home interview.
